Safety Considerations
1-1
Safety Guidelines
Our granulators are designed to provide safe and reliable operation
when installed and operated within design specifications, following
national and local safety codes.
To avoid possible personal injury or equipment damage when
installing, operating, or maintaining this granulator, use good
judgment and follow these safe practices:
X LEARN AND OBEY your company’s safety policy regarding
granulating equipment.
X MOVING OR LIFTING THE GRANULATOR: Although
our equipment is built and engineered for great ruggedness in
operation, care must be taken when moving the machine along
the floor or lifting it. Damage may occur to sheet metal covers,
electrical cabinets, or small brackets if pressure is applied to
them when moving the granulator. When lifting the granulator,
be certain of total machine weight and the capability of the
lifting equipment. (See the Granulator Specification Sheets for
machine weights and dimensions.)
X GRANULATOR LOCATION: Adequate area for routine
maintenance should be provided in order to open the machine
for knife, screen, or cleanout service. Proper service area
clearances also should allow people who are working on the
machine to be clearly visible to others, thereby reducing the
potential safety hazards.
X SAFE HOUSEKEEPING: The work area must be kept clean
and uncluttered during periods of operation or maintenance. No
hand tools or other metal objects should be left on or around
the machine. Any tools or other metal objects which
mistakenly fall into the hopper feed opening can cause severe
damage to internal cutting chamber and screen chamber
components.
X SAFETY GLASSES OR A FACE SHIELD MUST
ALWAYS BE WORN when servicing or operating the
machine. Although our machines are designed for the
maximum in flyback control, caution must be used when
operating near the hopper feed opening in order to guard
against unexpected material flyback.
Page 9 of 53
Download from Www.Somanuals.com. All Manuals Search And Download.
X EAR PROTECTION may be required when operating the
machine during granulation of very hard or noisy materials.
The Occupational Safety and Health Act of 1970 has
established guidelines for Permissible Noise Exposures (OSHA
1910.95) that should be followed.
X NEVER attempt to operate the granulator unless it is fully
assembled with all guards and interlocks in place and
functional.
X OBSERVE all danger, warning, caution and safety labels on
the equipment.
X Upon completion of any machine maintenance, be certain ALL
SAFETY GUARDS AND COVERS are securely and
properly fastened prior to resuming machine operation. All
fasteners must be in place and properly tightened. ANY
SHORTCUTS MAY RESULT IN INJURY TO
PERSONNEL OR DAMAGE TO EQUIPMENT.
X NEVER wear any loose fitting clothes, neckties, or dangling
items such as earrings, belts, or shoestrings. Jewelry, such as
wristwatches, bracelets, or rings should NEVER be worn. Long
hair must be tied back or placed in a tight fitting hairnet.
NEVER lean against or rest hands or feet on the granulator
when it is in operation or open for maintenance. NEVER stand
on the granulator when it is in operation.
X ROTATION OF MOTORS: All rotating items in the
granulator are clearly marked on the machine. Always check
for proper rotation of motors.
X ELECTRICAL GROUNDING: All electrical equipment on
the granulator must be grounded in accordance to all local
codes and Article 250 of the National Electric Code.
X ALWAYS DISCONNECT AND LOCKOUT the main
electrical power to the granulator before performing any
service.
X SAFETY INTERLOCKS MUST NOT BE BYPASSED.
The mechanical and electrical safety interlocks ensure the
safety of personnel. They should never be tampered with or
removed for ANY reason. They should be checked frequently
by a qualified mechanic for proper operation.
X NEVER modify the machine configuration or any individual
component without written consent from Sterling Corp.

Safety Procedures
1-2-1 Guidelines for Moving the Granulator
To lift and move the granulator safely and correctly, cover any
sharp corners or edges, and use the type of equipment that has the
most appropriate features and capacity.
Before lifting, check that there are no items that could fall during
lifting.
Before positioning the granulator, check that the floor is level and
is strong enough to support the load, that there is adequate space in
the installation area to allow the movement of equipment necessary
to the task and to enable any necessary maintenance work to be
carried out unhindered.
1-2-2 Clearing a Jammed Cutting Chamber
1. Disconnect and lockout power.
2. Be certain that the rotor is motionless.
3. Open the front panel and remove the bin.
4. Unscrew the screw knob, which keeps the hopper and screen
cradle in place.
5. Remove the screen.

!! CAUTION !!
NEVER ATTEMPT TO FREE A JAMMED MACHINE BY PLACING HANDS ON
ROTOR, ROTOR KNIVES, OR WITHIN THE CUTTING CHAMBER.
HANDS MUST BE KEPT CLEAR OF THE ROTATIONAL PATH OF THE ROTOR
KNIVES.
A block of wood should be used to exert force on the rotor, usually
in the direction opposite normal rotation.
Good footing on a clean floor is essential and the body should be
well braced when performing this act. Guard against loss of
balance should the jammed conditions suddenly come free.
A leather mallet and block of wood of sufficient length to keep
hands away from the path of knives can be used if required.
Use pliers in removing material from the cutting chamber, keeping
in mind that the removal of material may cause rotation of the rotor
and rotor knives.
After clearing the jam, be certain that the hopper screen, and all
guards and covers are secured in place before connecting power
and starting the machine.

Safety Features
The granulators are equipped with safety features intended to
protect personnel and the granulator. Do NOT remove or tamper
with such equipment.
1-3-1 Safety Features Fitted On the Granulator
All moving drive parts, including the two pulleys and the belt, are
contained in a guard, which may only be removed using specific
tools and moreover cannot be fixed in the correct position without
special fastenings.
Warning!
Always make sure that the guard is in position before starting the granulator.
Page 12 of 53

The upper part of the cutting chamber is protected by the feed
hopper, used to insert material to be granulated while the lower
part is protected by the screen, and screen support. These
components are fixed by a screw knob, unscrewing releases a
safety switch key (Figure 1), which cuts off the electric supply to
the motor, causing the rotor to stop.
The method of opening the granulator has been designed to restrict
operator access, allowing the rotor and all moving knives to stop
completely. To allow operator access more quickly could be
dangerous as it might be possible to make contact with the
granulator knives while they are still rotating.

Uncrating Your Granulator
Prepare in advance the site you have selected for installation of the
granulator. Be certain that the area to be occupied by the machine
is clean, level, and free of obstructions. The site you have selected
must have a floor rating to adequately support the weight of the
machine.
Your granulator is mounted on a wooden skid and blocked and
banded to secure it for shipment. All non-painted items subject to
corrosion are coated with a quality rust preventative, and the
machine is covered with heavy-duty polyethylene to protect it from
moisture and dirt. Granulators are normally shipped completely
assembled unless the size of the machine or an agreement for
special shipping arrangements prompts partial assembly.
If inspection, after shipment, has revealed no shipping damage,
unpack the unit by removing the polyethylene protective covering
and banding. Remove the envelope with the parts list, assembly

drawings, electrical schematics, and manual from the base
evacuation area.
You can now have the machine lifted from the skid. A forklift is
ideal for the purpose, but take care to properly position the forks
between the casters and the centrally mounted evacuation pipe
from the side of the machine. (See Figure 8)
Figure 8: Lifting the Granulator
! CAUTION !
Do not attempt to lift the granulator by means of any shaft or protruding member,

Lifting
Important!
Before lifting or moving the granulator, check the relative weight shown on the
shipping papers and in Figure 7.
To facilitate the lifting operation using forklift trucks, the drop box
has been removed from the granulator and is packed with any
spare parts.
When using a forklift to move the granulator, make sure it is
suitable for the weight and dimensions of the granulator. When
moving, take care not to damage delicate parts. To lift the machine
with a forklift, place the carriage forks under its base (See Figure
8). Where a forklift truck is not available, it is possible to use
cables or belts, provided that they are strong enough to support the
weight of the granulator, then carry out the lifting procedure.
Important!
During the movement, the load must remain in a horizontal position, regardless of
the type of equipment used.
4-2
Positioning the Granulator
Important!
Make sure that the base on which the granulator is supported is solid and
completely level, in order to rigidly support the granulator without its being
subjected to vibration. It is recommended that the floor be reinforced concrete
with a very smooth support surface.
Place the granulator in an area large enough to allow sufficient
space on all sides for the operator to carry out maintenance.
Although the granulator controls and electrical components
comply with CEE & NEMA codes and regulations, the machine
must be placed in an area free from humidity, dampness, and
Page 24 of 53
Download from Www.Somanuals.com. All Manuals Search And Download.
water. The granulator should be installed in an inside covered,
weather-proof environment and away from any areas where water
collects on the floor.
Once the granulator is in position, the front panel must be opened
in order to insert the bin as illustrated in Figure 9.
Figure 9: Inserting the Bin
4-3
Electrical Connection
It is extremely important that the machine is correctly wired into
the plant power source by a licensed electrician. See Section 9 for
a wiring diagram.
All electrical equipment must be properly grounded in accordance
with local and national codes to protect personnel from electrical
shock. A fusible, lockable disconnect between the plant power
source and the machine electrical cabinet is highly recommended.
!!Caution!!
Before connecting the power, check that the power cable size and capacity
corresponds to the horsepower and amp load indicated on the granulator label
and that the disconnect switch is in the OFF position. (See Figure 2.)
Unless otherwise specified, the granulator has been wired for 480
volts, 60 Hz, 3 ph.
The power cable from the plant source can be run directly to the
control panel or through the base of the machinery. To run the
power cable through the base of the granulator, perform the
following steps:
Page 25 of 53
Download from Www.Somanuals.com. All Manuals Search And Download.
1. Open the back cover, and insert the power cable from

4. Pivot back the feed hopper to gain free access to the cutting
chamber.
5. Check that there are no foreign objects in the cutting chamber.
6. Check to be sure the bed knife and rotor knife bolts are at the
proper torque and the knife gap is set according to
specifications. See Sections 4-4-4 and 6-4.
7. After completing the checks, close the hopper and screen, and
fasten them with the corresponding knobs; reinsert the bin.
Then close both the rear cover and the front panel.
8. Remove the drive belt guard by unscrewing the ten fastening
screws.
9. Manually give the rotor at least one complete turn using the
rotor pulley.
10. If there are no warning noises or signs of friction, this means
the cutting chamber is completely clear. Replace the belt guard,
remove lockout devices, and turn power on.

If the rotation direction is correct, the granulator is ready to use. If
the rotation direction is incorrect, reverse the rotor direction as
follows:
!!Warning!!
A LICENSED ELECTRICIAN must carry out this operation.
1. Disconnect and lockout the power to the machine at the
incoming power source. If the disconnect is not lockable,
remove the fuses.
2. Reverse any two of the three power line conductors to the
machine. If there is more than one motor on the machine and
only one is turning in the wrong direction, reverse any two of
the three line conductors at the overload relay for that motor.
3. Unlock the power and switch the electrical disconnect switch
to “ON”. (Replace the fuses if necessary.)
4. Re-check the rotation direction of the motors.
4-4-3 Test the Interlock Switches
With the cutting chamber and screen cradle closed and power On,
perform the following tests:
1. Push the start button to start the granulator.
2. Retract the screen cradle interlock actuator screw by turning it
counterclockwise. Make sure that the end of the actuator screw
is visible and clear of any contact. The granulator should stop.
3. If the machine continues to run, turn off and lockout the power.
4. Have the electrician check the interlock switch on the screen
cradle to correct the malfunction.
5. If necessary, engage the screen cradle interlock actuator screw.
Having completed the above procedures, close the control panel.
Unlock power or return the fuses in the supply panel, turning the
disconnect switch to “ON”. Pull the start button and release only
when the motor has started, then check again that the rotor is
turning in the correct direction.
4-4-4 Checking Knife Position
NOTE: This operation must be carried out by an operator /
mechanical maintenance engineer.
Page 28 of 53
Download from Www.Somanuals.com. All Manuals Search And Download.
Before undertaking any type of work on the machine, use a feeler
gauge to check the distance between the bed knives and the rotor
knives (the knife gap).
To access the cutting chamber, follow the same procedure and
observe the precautionary steps given in Section 4-4-1. Before
proceeding to the checks, it is advisable to block the rotor to avoid
any inadvertent rotation.
Once you have safely accessed the cutting chamber, check the
current distance between the bed knives and the rotor knives using
a feeler gauge. (See Figure 12.)
NOTE: The distance set by the manufacturer for normal
application is 0.006”-0.008” (0.15-0.20 mm). If the gap between
the bed knives and the rotor knives is found to be greater than that,
an adjustment must be made. (See Section 6-4: Inspection and
Adjustment of Knives.)
Once you have checked the knife gap, close the hopper, secure it
with the appropriate swing bolts, reinsert the bin, and close the
front panel.

Operation
The granulator can be operated in a vertical top feed position or in
a horizontal front feed position.
Before starting the granulator, always check for and remove tools
or any other objects placed on the granulator. Turn the Power
disconnect switch to “ON”, pull the Start button, and release it
when the motor has started.
It is quite normal for the motor not to start immediately, as the
electronic system must check all the micro switches before
enabling start up procedures. Wait for the electric motor to reach
normal rotating speed before feeding the granulator.
!!Warning!!
Never push material into the hopper with hands.
If the hopper becomes blocked, the granulator must be turned off,
and the power must be locked out or the fuses removed.
Before stopping the granulator for the end of a working shift or for
any other reason, stop feeding in the material to be granulated, and
leave the granulator running for several minutes to allow the
cutting chamber to completely granulate and empty the material
inside. Press the lighted Start/Stop button, which will immediately
turn off the granulator.
Important!
If the granulator stalls frequently during use, it may be necessary to adjust the
calibration of the “overload.” (Refer to the values shown in the electrical
diagram.)

Monthly Maintenance Operations
6-2-1 Drive Belt Tension
NOTE: This operation should be carried out by an operator /
mechanical maintenance engineer.
For the granulator to function correctly, it is extremely important
that the drive belt is always tight. Correct tension reduces the load
of the rotor bearings and minimizes wear and stretching of the belt.
To check and adjust belt tension, carry out the following
procedure:
1. Turn off the machine and lockout power by using the
disconnect switch, or remove the fuses from the electrical
control panel.
2. Remove the belt guard by unscrewing the ten screws that hold
it in place.
3. Open the front panel.
4. Remove the bin.
5. Open the rear panel.
6. Loosen the nuts that lock the motor base slide.
7. Loosen the tie rod
8. Adjust the belt tension, turning the tie rods forward.
9. Turn the tie rod to bring the motor square to the belt axis.
10. After the adjustment, lock the nuts again, and close the rear
panel, refitting the proper locking latch.
11. Reinsert the bin, close the front panel, refit the belt guard and
unlock the power or replace the fuses in the control panel.
6-2-2 Proper Belt Tension
Measure the belt span and divide by 64 to get the allowable belt
deflection. With a belt gauge, measure the force it takes to deflect
the belt the amount calculated.
NOTE: Check your belt gauge’s instructions for proper scale
settings. Belt tension gauges are available from customer service or
your belt manufacturer.
Compare the gauge reading with the chart value for the belt cross-
section used. (See Figure 14)

For best performance, the force measured on the gauge should be
between the minimum and maximum values shown on the chart. If
there is not enough deflection force, the belts should be tightened.
If there is too much deflection force, the belts should be loosened.
6-2-3 Belt Replacement
Important!
It is very important to replace all belts at the same time.
If the drive belts have to be replaced, follow the procedure in
Section 6-2-1 up to Step 6. Then release the belt from tension by
fully unscrewing the tie rods. Slip off the belts, and replace them
with new ones. Continue with the procedure for adjusting the belt
tension.
6-3
Removal and Replacement of the Screen
NOTE: A qualified operator/maintenance mechanic should
carry out this procedure.
1. Switch the machine off and lockout power by turning the
disconnect switch to “OFF”, or remove the fuses from the main
control pane.
2. Open the front panel.
3. Remove the bin.
∗ The Deflection Force Value shown is for each belt and must be multiplied by the number of V-belt
elements if all are deflected.
Page 34 of 53

4. Remove the screw knob that holds the hopper on top of the
cutting chamber. Carefully lower the screen cradle assembly,
resting it on the base.
5. Remove the screen, keeping it in a horizontal position. (See
Figure 15.)
6. Replace the screen with a new one, tighten the screw knob,
reposition the bin, and close the front panel. Unlock the power
and turn the machine back on.
Figure 15: Removing the Screen
6-4
Inspection and Adjustment of Knives
NOTE: This operation must be performed by a qualified
operator / mechanical maintenance technician.
Important!
Before carrying out any maintenance on the cutting chamber, the operator must
wear work gloves thick enough to avoid injury to the hands while touching sharp
parts or the cutting edges of the blades.
To inspect blades, remove the screen by following steps 1-5 in
Section 6-3. Then, proceed as follows:
1. Open the rear-closing panel by releasing the locking latch.
2. Pivot the in-feed hopper completely back to gain clear access
to the cutting chamber, and clear any process material or
foreign objects between the knives.
3. Turn the rotor slowly until the first row of rotor knives are in
close proximity to the bed knife cutting edge. Turn the rotor
backwards, keeping hands and fingers from directly contacting
sharp knife-edges.
Page 35 of 53
Download from Www.Somanuals.com. All Manuals Search And Download.
4. Using a feeler gauge, measure the gap between the rotor and
knife cutting edges. Check each rotor knife to find the “high
knife” or the knife that measures the smallest gap. If the gap is
substantially greater than the specified 0.006” - 0.008” (0.15
mm – 0.2 mm), the knives need readjustment.
5. Loosen the bed knife locking bolts. (See Figure 16.)
6. Leave the two outside bolts just tight enough to allow the bed
knife to move.
7. Loosen the adjustment screws and lock nuts. (See Figure 16.)
8. Insert a 0.006” – 0.008” (0.15 mm – 0.2 mm) thickness gauge
between the cutting edge of the bed knife and that of the high
rotor knife.
9. Adjust the bed knife into the rotor knife using the adjustment
screws, so as to leave enough space for the thickness gauge to
move.
NOTE: Check that the distance between the fixed and rotating
knife is the same at both ends of each knife. Move the bed
knife using the push adjusting screws a little at a time on each
end.
10. When adjustment is complete, tighten the lock nuts on the
adjustment screws.
11. Torque the bed knife bolts to 95 lbs./ft. (13 Kgm., 128 Nm)
using a torque wrench.
12. Repeat the steps 4-11 to adjust the rear (or down stroke) bed
knife. Turn the rotor slowly for one complete revolution,
checking the exact distance between all the rotary knives and
the bed knives.
13. Close the hopper and replace the screen and screen cradle,
securing them in place using the swing bolts provided.
14. Close the front and rear doors, and unlock the power or replace
the fuses in the control panel. Turn the disconnect switch to
“ON”.

Removing and Replacing Bed Knives
NOTE: This procedure should be performed by a qualified
operator / maintenance mechanic. Protective gloves must be
worn to avoid injury when handling the cutting knives.
To remove and replace bed knives, complete the following
procedure:
1. Open the granulator by following Steps 1-5 in Section 6-3.
2. Open the rear-closing panel by releasing the locking latch.
3. Pivot the in-feed hopper completely back to gain clear access
to the cutting chamber, and clear any process material or
foreign objects from between the knives.
4. Rotate the rotor so that the rotor knives will not interfere with
the removal of the bed knife. Using a wooden block, block the
rotor to prevent it from rotating while removing the knives.
5. Loosen the lock nuts and back off the adjustment screws. (See
Figure 16.)
6. Loosen and remove the bed knife bolts and lift the upper
shield, positioned above the knife, removing it from the cutting
chamber. The bed knife may now be removed.
7. Perform the above steps to remove the rear (upstroke) bed
knife as well.
NOTE: Before replacing the bed knife with new or sharpened
knives, wipe the knife seats on the knife block, being sure to
clean off all process material. The tapped holes in the knife
block (used for holding the knives in place) should be clear of
any dirt, oil, or process material.
Page 37 of 53
Download from Www.Somanuals.com. All Manuals Search And Download.
8. Install new or sharpened bed knives on each knife seat, making
sure that the rotor is blocked to prevent it from rotating while
installing each knife. Be sure to place the bed knives in the
correct positionsthe rear (down stroke) bed knife must be
placed with the extended cutting edge on top, and the front
(upstroke) bed knife should be placed with the cutting edge on
the bottom.
9. Replace the upper shields in position above the bed knives. The
shield on the rear (down stroke) bed knife should be positioned
so that the inside edge is set back approximately 1/32” from the
cutting edge below it.
10. Before re-installing the knife bolts, wipe them clean with a
lightly oil-damped cloth. Do not leave an oil film on the bolt
since lubrication can adversely affect the stress on the bolt
when torqued to the specified values. It is recommended that
the knife bolts be replaced with each new set of knives. This
will reduce the risk of bolt failure due to overstretching.
Always use the specified replacement bolts.
11. Tighten the bed knife bolts at each end of the knife just enough
to keep the knife in place, while still allowing the adjusting
screws to move the knife forward. The remaining bolts can be
left hand tight until the knife is adjusted.
12. Adjust the knife gaps with the rotor knives and close the
machine, following Steps 8-14 in Section 6-4.
6-6
Removal and Replacement of Rotating Blades
NOTE: A qualified operator / maintenance mechanic should
perform this operation. Protective gloves must be worn to
avoid injury when handling the cutting knives.
To remove and replace rotor knives, complete the following
procedure:
1. Open the granulator by following Steps 1-5 in Section 6-3.
2. Open the rear-closing panel by releasing the locking latch.
3. Pivot the in-feed hopper completely back to gain clear access
to the cutting chamber, and clear any process material or
foreign objects from between the knives.
4. Rotate the rotor so that the knife bolts are in a convenient
position to remove the bolts with the appropriate wrench.
Using a wooden block, block the rotor to prevent it from
rotating while removing knives or after a knife has been
removed.
Page 38 of 53
Download from Www.Somanuals.com. All Manuals Search And Download.
5. Loosen and remove the knife bolts and lift the knife off the
knife seat removing it from the cutting chamber.
6. Perform the above steps until all the rotor knives are removed.
NOTE: Before replacing the rotor knife with new or sharpened
knives, wipe the knife seats on the rotor, being sure to clean off
all process material. The tapped holes in the rotor (used for
holding the knives in place) should be clear of any dirt, oil, or
process material.
7. Loosen the bed knife bolts and adjusting screws, and pull back
the bed knife so that the rotor knives will collide as they are
installed and rotated.
8. Install new or sharpened knives on each knife seat, making
sure that the rotor is still blocked to prevent it from rotating
while installing each knife.
9. Before re-installing the knife bolts, wipe them clean with a
lightly oil-damped cloth. Do not leave an oil film on the bolt
since lubrication can adversely affect the stress on the bolt
when torqued to the specified values. It is recommended that
the knife bolts be replaced with each new set of knives. This
will reduce the risk of bolt failure due to overstretching.
Always use the specified replacement bolts.
10. Tighten each set of the knife bolts; making sure that the knife is
seated against the back heel in the rotor seat. Before torquing
the bolts, check that a 0.001” feeler gage cannot fit between the
heel and the back of the knife.
11. Torque the rotor knife bolts to 100 Lbs./ft. (14 Kgm, 135 Nm).
12. Adjust the knife gap with the bed knives and close the
machine, following Steps 8-14 in Section 6-4.

Specifications for Re-sharpening Bed Knives
Every bed knife has two cutting edges, one on each side. When a
blade becomes worn, the knives can be rotated. To regrind these
knives, refer to the data shown in Figure 17. Replacement of these
knives is necessary when their length falls below the recommended
tolerance.

Specifications for Re-sharpening Rotor Knives
All the rotor knives must be re-sharpened in sets. Each knife within
a set must have a tolerance within 0.003” (0.05 mm) for the total
height, heel to cutting edge. Greater variations within a set will
result in improper knife gap settings and other operational
problems. See Figure 18 for rotor knife specifications.
Knives below the minimum dimension specified must not be used.
Using knives below the specified minimum can cause interference
resulting in serious damage to the rotor and cutting chamber.
When using a surface grinder to re-sharpen the rotor or bed knives,
it is not harmful to allow a few small nicks to remain on the cutting
edge. Grinding the knife so that the cutting edge is free from all
nicks can be wasteful.

purchaser, and which, in the Company’s opinion, are defective. Any replacement part assumes the
unused portion of this warranty.
This parts warranty does not cover any labor charges for replacement of parts, adjustment repairs, or any
other work. This warranty does not apply to any equipment which, in the Company’s opinion, has been
subjected to misuse, negligence, or operation in excess of recommended limits or which has been
repaired or altered without the Company’s express authorization. If the serial number has been defaced
or removed from the component, the warranty on that component is void. Defective parts become the
property of the warrantor and are to be returned.
The Company is not liable for any incidental, consequential, or special damages or expenses. The
Company’s obligation for parts not furnished as components of its manufactured equipment is limited to
the warranty of the manufacturers of said parts.
Any sales, use, excise, or other tax incident to the replacement of parts under this warranty is the
responsibility of the purchaser.
The company neither assumes nor authorizes any other persons to assume for it any liability in
connection with the sale of its equipment not expressed in this warranty.
Many types of Sterling equipment carry an additional one-year service policy. Consult your Sterling sales
representative for specific details.
