Grounding Instructions
Electrical connections must
be made by
a
qualified electrician in
compliance with all relevant codes. This
machine must be properly grounded to help
prevent electrical shock and possible fatal
injury.
This machine must be grounded. In the event of
a malfunction or breakdown, grounding provides
a path of least resistance for electric current to
reduce the risk of electric shock.

This band saw is pre-wired for 115 volt and is
equipped with an electric cord having an
equipment-grounding
conductor
and
a
grounding plug similar to that shown in Figure 6.
The plug must be inserted into a matching outlet
that is properly installed and grounded in
accordance with all local codes and ordinances.
Do not modify the plug provided. If it will not fit
the outlet, have the proper outlet installed by a
qualified electrician.
Improper connection of the equipment-
grounding conductor can result in a risk of
electric shock. The conductor, with insulation
having an outer surface that is green with or
without yellow stripes, is the equipment-
grounding conductor. If repair or replacement of
the electric cord or plug is necessary, do not
connect the equipment-grounding conductor to a
live terminal.
Figure 6
Check with a qualified electrician or service
personnel if the grounding instructions are not
completely understood, or if in doubt as to
whether the machine is properly grounded. Use
only three wire extension cords that have three-
prong grounding plugs and three-pole
receptacles that accept the machine’s plug.
115 Volt Operation
As received from the factory, your band saw is
ready to operate at 115 volt power, using an
outlet and a plug that look similar to those
illustrated in Figure 6.
A temporary adapter, which looks like the
adapter illustrated in Figure 7, may be used to
connect this plug to a two-pole receptacle as
shown, if a properly grounded outlet is not
immediately available. The temporary adapter
should only be used until
a
properly
grounded outlet can be installed by a
qualified electrician.
The green colored rigid ear, lug or tab,
extending from the adapter must be connected
to a permanent ground such as a properly
grounded outlet box, as shown in Figure 7.
Figure 7
Check with a qualified electrician or service
personnel if the grounding instructions are not
completely understood, or if in doubt as to
whether the tool is properly grounded.
Make sure the voltage of your power supply
matches the specifications on the motor plate of
the Band Saw.
Conversion to 230 Volt
If 230 volt operation is desired, the following
instructions must be followed:
11

Adjustments
Squaring Vise to Blade (90° Stop)
For accurate cutting, the vise jaws should be
square to the blade. Inspect as follows:
1. Loosen the handle (A, Figure 10) and make
sure the bow is swiveled enough that the
stop screw (B, Figure 10) is contacting the
fixed screw (C, Figure 10).
2. Place a machinist’s square on the bed
against the blade and the fixed jaw of the
vise, as shown in Figure 10. The square
should lie along the entire length of the jaw
and blade without a gap.
Figure 10
3. If the vise and blade are not square, loosen
the hex nut on the stop screw (B, Figure 10)
with a 10mm wrench and rotate the stop
screw as needed until the vise and blade
are square whenever the stop screw is
contacting the socket head cap screw (C,
Figure 10).
12
Download from Www.Somanuals.com. All Manuals Search And Download.
4. If the vise and blade are square but the
pointer (D, Figure 10) is off slightly, loosen
the screw and adjust the pointer until it lines
up with zero on the scale. Tighten the
screw.
NOTE: The handle (A, Figure 10) is adjustable.
Simply lift up on the handle and rotate it on the
pin. Release the handle, making sure it seats
itself properly on the pin.
Setting 45° Stop
Swivel the bow to the 45° angle. Use a
machinist’s protractor or similiar 45° device to
check the blade’s angle to the vise.
If adjustment is needed, loosen the hex nut on
the 45° stop (E, Figure 10) and rotate the screw
as needed with a 10mm wrench. When satisfied,
tighten the hex nut.
Setting Downfeed Rate
The downfeed rate of the blade is important to
band saw performance. Excessive pressure of
blade against the workpiece may break the
blade or stall the saw. In contrast, insufficient
pressure rapidly dulls the blade.
Turn the valve lever (F, Figure 11) parallel to the
hydraulic cylinder (K, Figure 11) to lower the
bow. The rate of downfeed is adjusted by the
dial (G, Figure 11).
The stop screw (H, Figure 11) prevents the
blade from contacting the base after the cut. It
has been adjusted at the factory. If future
adjustment is ever needed, loosen the hex nut
(J, Figure 11) with a 14mm wrench and rotate
the screw (H, Figure 11) as needed, then re-
tighten the hex nut (J, Figure 11).
Figure 11
Positioning the Vise
Keep hands away from blade
while adjusting the vise.
1. The workpiece is placed against the fixed
jaw on the right, which has already been
squared (see “Squaring Vise to Blade”).
2. The vise has a quick-release feature which
allows fast positioning of the movable jaw
against the workpiece. Disengage the lead
screw by rotating the vise handwheel
counter-clockwise about 1/2 turn. See
Figure 12.
Figure 12
13
Download from Www.Somanuals.com. All Manuals Search And Download.
3. Slide the movable jaw by hand until the jaw
contacts the workpiece.
4. Rotate the vise handwheel clockwise to re-
engage the lead screw, and continue the
tightening process of the jaw until the
workpiece is securely clamped.
5. The quick release function can be used to
back off the movable jaw when the cut is
finished.
Miter Cuts
There are two sets of holes in the base for
mounting the vise assembly. For miter cuts from
0° up to 45°, mount the vise assembly to the
rear set of holes. For miter cuts over 45° up to
60°, use the vise in the front set of holes. See
Figure 13.
To change the vise to the 60° position:
1. Disconnect band saw from power source.
2. Raise the bow out of the way. Make sure
the hydraulic cylinder is closed (valve
lever perpendicular to cylinder) so the
bow remains stationary.
3. Remove the two socket head cap screws
and lock washers which secure the vise,
and lift off the vise. See Figure 13.
Figure 13
4. Move the bushings from the first set of holes
to the other set of holes as shown.
5. Mount the vise to the new set of holes,
tightening the two socket head cap screws
and lock washers.
6. Remove the socket head cap screw (C,
Figure 10) to allow the bow to swivel.
7. The cutting operation will now take place at
the opposite side of the vise. Swivel the bow
until the pointer lines up with 60° on the
angle scale, and tighten the handle.
NOTE: If the handle becomes too
constrained to be easily tightened while at
the 60° position, lift up on the handle and
use a hex wrench to tighten the pin, then
fully tighten using the handle itself. See
Figure 14.
8. Move the chip pan and the work stop to the
other side of the vise.

Blade Tension
Use the knob (Figure 15) to tension the blade.
Clockwise tightens the blade, counterclockwise
loosens it.
Blade Tracking
Tracking the blade requires
that the band saw be operating while the
back blade cover is removed. Use extreme
caution and keep hands away from blade.
The blade provided with your band saw has
already been tracked at the factory and requires
no adjustment.
When the blade is replaced, tracking may be
required for the new blade. It is recommended
that tracking be done by a person experienced
in these procedures and aware of the dangers
involved.
1. Turn the socket set screw (Figure 15) as
needed to shift the angle of the idler wheel.
NOTE: This adjustment is sensitive; do it
gradually and in small increments allowing
the wheel to respond to the changes.
Figure 15
2. Tracking is set properly when the back of
the blade lightly touches the wheel shoulder.
NOTE: Over-tracking (allowing blade back
to rub hard against wheel shoulder) will
damage the blade wheels and blade.
Setting Blade Speed
1. Disconnect band saw from power source.
2. Open the pulley cover.
3. Loosen the knob (see A, Figure 3) and lift
up on the motor. Move the belt to the
desired pulley grooves. A chart is affixed to
the inside of the belt guard showing the
positions for the three speeds, 80, 120 and
200 surface feet per minute (SFPM). This
chart is also shown in Figure 16.
4. Push the motor back down to tension the
belt, and tighten the knob (A, Figure 3).
Material chips or shavings are the best indicator
of proper blade speed and downfeed rate. The
ideal chip is thin, tightly curled and warm to the
touch. Chips that range from golden brown to
black indicate excessive force. Blue chips
indicate extreme heat from too high a blade
speed, which will shorten blade life. Thin or
powdered chips indicate insufficient downfeed
rate.
Figure 16

Belt Tension
1. Disconnect band saw from power source.
2. Open the pulley cover.
3. Loosen the knob (see A, Figure 3), and
push down on the motor to tighten the belt.
4. Tighten the knob (A, Figure 3).
5. Check the tension by using moderate finger
pressure about midway between the
pulleys. The belt should deflect about 1/2”.
See Figure 17.
6. Close the pulley cover.
Blade Guide Assembly
The blade guide assembly should be moved as
close to the workpiece as possible without
interfering with the cutting operation. This allows
minimum exposure of the blade. To adjust,
loosen handle (A, Figure 18) and slide the
assembly into position. Always tighten handle
(A, Figure 18) after adjustment.
Figure 17
Guide Bearings
The blade guide bearings come pre-adjusted
from the factory, but should be inspected
frequently and future adjustments made as
needed, especially after changing blades.
The blade should have already been tensioned
and tracked properly before adjusting the blade
guides.
1. Disconnect band saw from power source.
2. Loosen slightly the hex cap screw (B, Figure
18) with a 12mm wrench.
3. Slide the guide block (C, Figure 18) down
until the thrust bearing (D, Figure 18) just
contacts the back edge of the blade.
4. Tighten the hex cap screw (B, Figure 18).
Figure 18
5. The front bearing (E, Figure 18) is eccentric,
and should be adjusted so that it just
contacts the blade without pinching the
blade or interfering with its movement.
Proceed as follows:
8. Hold the bearing at that position with the
wrench on the hex nut, to prevent the
bearing from moving. At the same time,
tighten the upper hex nut (F, Figure 18) with
the other wrench.
6. Loosen the hex nut (F, Figure 18) with a
14mm wrench.
7. Use a 12mm wrench to rotate the small hex
nut just above the bearing (G, Figure 18)
until the bearing is just contacting the blade.
9. Repeat these steps for the other blade guide
assembly.

Blade Replacement
Use caution and proceed
slowly when working with or around a band
saw blade. Use gloves when handling it.
1. Disconnect band saw from power source.
2. Remove the knob and the back blade cover
from the band saw. See Figure 19.
3. Loosen the handle on the blade guide (A,
Figure 18) and lower the blade guide as far
as it will go. See Figure 19.
4. Release tension on the blade.
5. Remove old blade and install new one by
placing it between the guides and around
the band wheels. Make sure the blade is
oriented properly so that the teeth will point
downward and into the workpiece (Figure
20). An arrow on the the body of the bow
indicates blade direction (shown in Figure
15).
Figure 19
6. The blade should be tensioned and tracked
properly before operating. See “Blade
Tension” and “Blade Tracking” above.
Automatic Shut-Off
At the end of a cut, the screw (A, Figure 21)
contacts the paddle switch, shutting off the
machine. The screw has been set at the factory.
If future adjustment is needed, loosen the hex
nut (B, Figure 21) with a 12mm wrench and
rotate the screw as needed, then re-tighten the
hex nut.
Figure 20
NOTE: The bow must be raised in order to re-
start the band saw.
Switch Lock-Out
The switch has a removable piece (C, Figure
21). When this is removed, the band saw cannot
be activated. To start the band saw, first snap
this piece back into place.

Vertical Bow Position
1. The band saw can be placed in vertical
position to facilitate blade changes,
maintenance, etc. Unscrew the knob (Figure
22) and slide it out to disengage the
hydraulic cylinder.
2. Raise the bow all the way.
3. The stop screw (Figure 23) has been pre-
set at the factory. If further adjustments are
needed, loosen the hex nut and rotate the
screw as needed. Re-tighten the hex nut.
Figure 22
Operation
Important: This band saw is designed for dry
cutting operations only.
General Operating Procedure:
1. Verify that all guards, covers, etc. are in
place and in working order, the blade is
tensioned properly, and the blade guides
are set correctly.
2. Position belt on the pulleys to achieve
desired speed. Close pulley guard when
finished.
3. Place workpiece in vise and tighten vise.
The workpiece should be fitted directly
between the jaws without adding other
objects.
Figure 23
When the workpiece to be cut is a profiled
section, flat piece or special shape, refer to
the examples shown in Figure 24 for proper
clamping positions. The top row shows
acceptable clamping positions, the bottom
row shows unacceptable positions.
If the thickness of the profiled section is very
thin, a piece which duplicates the profile
should be fitted inside the workpiece itself,
to prevent the workpiece being crushed
between the jaws.
Never hold a workpiece by
hand when cutting it – the workpiece should
be firmly secured in the vise. Do not reach
into the cutting area during cutting
operations.
4. Pull up the paddle switch to start blade
movement.

5. Open the valve on the hydraulic cylinder to
allow the bow to descend in a gradual and
controlled manner.
Clean the machine of chips, shavings, etc. with
a rag or brush. Do not use your hands.
If the power cord is worn, cut, or damaged in
any way, have it replaced immediately.
6. The machine will shut off at the completion
of the cut. Remove the workpiece.
The ball bearings on the blade guide assemblies
are self-contained and sealed. They require no
further lubrication.
7. Close the hydraulic cylinder valve, and raise
the bow in preparation for the next cut.
Occasionally grease the lead screw on the vise.
Maintenance
Before doing maintenance on
the machine, disconnect it from the electrical
supply by pulling out the plug or switching
off the main switch. Failure to comply may
cause serious injury.
