SECTION 1: SAFETY
For Your Own Safety, Read Instruction
Manual Before Operating this Machine
The purpose of safety symbols is to attract your attention to possible hazardous conditions. This
manual uses a series of symbols and signal words which are intended to convey the level of
importance of the safety messages. The progression of symbols is described below. Remember
that safety messages by themselves do not eliminate danger and are not a substitute for proper
accident prevention measures.
Indicates an imminently hazardous situation which, if not avoided,
WILL result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided,
COULD result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided,
MAY result in minor or moderate injury. It may also be used to alert
against unsafe practices.
This symbol is used to alert the user to useful information about
proper operation of the machine.

Additional Safety for Jointers
1. JOINTER KICKBACK. "Kickback" is when
6. KICKBACK ZONE. The "kickback zone"
is the path directly through the end of the
infeed table. Never stand or allow others to
stand in this area during operation.
the workpiece is thrown off the jointer table
by the force of the cutterhead. Always use
push blocks and safety glasses to reduce
the likelihood of injury from kickback. If you
do not understand what kickback is, or how
it occurs, DO NOT operate this machine.
7. MAXIMUM CUTTING DEPTH. The maxi-
1
mum cutting depth for one pass is ⁄8".
Never attempt any single cut deeper!
2. OUTFEED TABLE ALIGNMENT. Keep the
knives alingned at top dead center (the
highest point during rotation) with the sur-
face of the outfeed table to avoid kickback
and personal injuries.
8. JOINTING WITH THE GRAIN. Jointing
against the grain or jointing end grain is
dangerous and could produce chatter or
excessive chip out. Always joint with the
grain.
3. PUSH BLOCKS. Always use push blocks
whenever surface planing. Never pass your
hands directly over the cutterhead without a
push block.
9. GUARDS IN PLACE. All operations must
be performed with the guard in place.
10. PROPER CUTTING. When cutting, always
keep the workpiece moving toward the
outfeed table until the workpiece has passed
completely over the cutterhead. Never back
the work toward the infeed table.
4. WORKPIECE SUPPORT. Supporting the
workpiece adequately at all times while
cutting is crucial for making safe cuts and
avoiding injury. Never attempt to make a cut
with an unstable workpiece.
11. SAFE KNIFE PROJECTION. Knives should
never be set in the cutterhead so they proj-
ect more than 0.125" (1⁄8"). Incorrectly set
knives may come loose during operation,
may become damaged, or may damage the
cutterhead.
5. USING GOOD STOCK. Jointing safety
begins with your lumber. Inspect your
stock carefully before you feed it over the
cutterhead. Never joint a board that has
loose knots, nails, or staples. If you have
any doubts about the stability or structural
integrity of your stock, DO NOT joint it!
12. MOUNTING. Keep the jointer firmly mount-
ed to your workbench or jointer stand.
No list of safety guidelines can be complete.
Every shop environment is different. Always
consider safety first, as it applies to your
individual working conditions. Use this and
other machinery with caution and respect.
Failure to do so could result in serious per-
sonal injury, damage to equipment, or poor
work results.
Like all machines there is danger associ-
ated with the Model G0612. Accidents are
frequently caused by lack of familiarity or
failure to pay attention. Use this machine
with respect and caution to lessen the pos-
sibility of operator injury. If normal safety
precautions are overlooked or ignored, seri-
ous personal injury may occur.

Circuit Requirements
We recommend connecting this machine to a
dedicated circuit with a verified ground, using the
circuit size given below. Never replace a circuit
breaker with one of higher amperage without con-
sulting a qualified electrician to ensure compli-
ance with wiring codes. If you are unsure about
the wiring codes in your area or you plan to
connect your machine to a shared circuit, you
may create a fire hazard—consult a qualified
electrician to reduce this risk.
Extension Cords
We do not recommend the use of extension
cords. Instead, arrange the placement of your
equipment and the installed wiring to eliminate
the need for extension cords.
If you must use an extension cord at 110V with
your machine:
Recommended Circuit Size...................15 Amps
•
•
•
Use at least a 14 gauge cord that does not
exceed 50 feet in length!
Plug/Receptacle Type
Included Plug/Receptacle ................ NEMA 5-15
The extension cord must also contain a
ground wire and plug pin.
Avoid cords over 50 feet long unless they
have been sized by a qualified electrician.

Mounting the Jointer
Cleanup
The unpainted cast iron surfaces are coated with
a waxy oil to protect them from corrosion during
shipment. Remove this protective coating with a
solvent cleaner or citrus-based degreaser such
as Grizzly’s G7895 Degreaser. To clean thor-
oughly, some parts may need to be removed. For
optimum performance from your machine,
make sure you clean all moving parts or slid-
ing contact surfaces that are coated. Avoid
chlorine-based solvents, such as acetone or
brake parts cleaner, as they may damage painted
surfaces should they come in contact.
Your Model G0612 jointer must be securely
mounted to a sturdy workbench. There are two
ways to do this—either with a direct mount or
with a through mount. We strongly recommend a
through mount. Whichever method you choose,
mount the jointer through the four holes in its cast
iron base. See Figures 7 and 8 for examples of
direct and through mounts.
���������
Site Considerations
�����������
Consider the jointer dimensions and size of mate-
rial to be processed through each machine, and
space for auxiliary stands, work tables or other
machinery when establishing a location for your
jointer. See Figure 6 for the Model G0612 over-
head view dimensions.

F. ON/OFF Switch: This paddle switch starts
and stops the cutterhead rotation. The yellow
part of the switch is a safety device. When
you remove this yellow key (by pulling it for-
ward and out), the switch locks in the OFF
position. Always remove this yellow key when
you leave the jointer work area. Removing
the key prevents unsupervised persons in
your shop (especially children) from easily or
accidentally starting the jointer.

G/H. Dust Collection Chute and Bag: This
assembly receives the debris removed from
the workpiece as it is cut. The internal fan
- powered by the jointer motor - pulls the
debris away from the cutterhead and blows it
through the chute into the bag.
Figure 22. G0612 parts and controls (back
view).
I. Fence Bracket Assembly
J. Fence Tilting Handle
K. Fence Sliding Handle
I. Fence Bracket Assembly: The various parts
of this assembly let you change the position
of the fence relative to the tables and secure
it in position during operation.
A. Outfeed Table: Supports the workpiece after
it passes over the cutterhead.
J. Fence Tilting Handle: Lets you change the
angle of the fence and lock it at the angle
desired. The fence can be quickly set to 90°
(perpendicular to the tables), 45° inward and
45° outward by setting and using the fence
stops on the bracket assembly.
B. Cutterhead Guard: Shields the cutterhead
to increase operator safety during operation.
The cutterhead guard is under spring tension;
it will always (unless blocked) snap forward to
hit the fence. DO NOT operate the jointer if
the guard is not functioning properly.
K. Fence Sliding Handle: This handle lets
you adjust and lock the position of the fence
across the tables. ALWAYS firmly tighten
the sliding handle before you begin opera-
tions. The position of the fence determines
the maximum width of the cut as you pass
your workpiece over the spinning cutterhead.
NEVER operate the jointer if ANY part of
cutterhead is exposed on the work area.
C. Fence: The fence guides the workpiece
uniformly over the cutterhead at the desired
angle.
D. Infeed Table: Supports the workpiece as it
is pushed over the cutterhead. The height
of the infeed table relative to the cutterhead
determines the depth of the cut.
E. Depth of Cut Adjustment Knob: This knob
lets you change the height of the infeed table
and thus control the depth of cut. Best results
are achieved when you limit the maximum
1
depth to /8" or less when edge jointing and
1/32" when surface planing. You can set the
depth of cut precisely with this adjustment
knob. To determine the depth of stock the
cutterhead will remove from your workpiece,
place a straightedge across the outfeed table
and use a ruler to measure the gap between
the straightedge and the infeed table.

To surface plane on the jointer:
Surface Planing
1. Read and understand SECTION 1:
SAFETY.
The purpose of surface planing on the jointer
is to make one flat face on the workpiece (see
Figures 32 & 33) to prepare it for surface planing
on a thickness planer.
2. Make sure you inspect your workpiece for
dangerous conditions as described in the
Stock Inspection & Requirements.
3. Set the cutting depth for your operation. (We
suggest 1⁄32" for surface planing.)
NOTICE
If you are not experienced with a jointer,
set the depth of cut to zero and practice
feeding the workpiece across the tables as
described. This procedure will better pre-
pare you for the actual operation.
4. Make sure your fence is set to 90˚.
5. If your workpiece is cupped (warped), place
the concave side (Figure 33) face down on
the surface of the infeed table.
6. Start the jointer.
Failure to use push blocks when surface
planing may result in cutterhead contact
with your hands, which will cause serious
personal injury. Always use push blocks to
protect your hands when surface planing on
the jointer.
7. With a push block in each hand, press the
workpiece down on the infeed table and
against the fence with firm pressure, then
feed the workpiece over the cutterhead, as
shown in Figure 32.
Figure 32. Typical surface planing operation.
Note: If your leading hand (with push block)
gets within 4" of the cutterhead, lift it up and
over the cutterhead, and place the push
block on the portion of the workpiece resting
on the outfeed table. Now, focus your pres-
sure on the outfeed end of the workpiece
while feeding, and repeat the same action
with your trailing hand when it gets within 4"
of the cutterhead. DO NOT place either hand
closer than 4" from the cutterhead! Failure
to heed this warning could result in serious
personal injury.

To edge joint on the jointer:
Edge Jointing
1. Read and understand SECTION 1:
SAFETY.
The purpose of edge jointing is to produce a fin-
ished, flat-edged surface (see Figure 34) suitable
for joinery or finishing. It is also a necessary step
when squaring rough or warped stock.
2. Make sure your stock has been inspected
for dangerous conditions as described in the
Stock Inspection instructions.
3. Set the cutting depth for your operation. (We
1
1
suggest between ⁄16" and ⁄8" for edge joint-
ing, using a more shallow depth for hard
wood species or for wide stock.)
NOTICE
If you are not experienced with a jointer,
set the depth of cut to zero, and practice
feeding the workpiece across the tables as
described below. This procedure will better
prepare you for the actual operation.
4. Make sure the fence is set to 90˚.
5. If your workpiece is cupped (warped), square
the stock before edge jointing by surface
planing the workpiece until it is flat on both
sides.
6. Start the jointer.
7. Press the workpiece against the infeed table
and fence with firm pressure. Use your trail-
ing hand to guide the workpiece through
the cut, and feed the workpiece over the
cutterhead, as shown in Figure 34.
Note: If your leading hand gets within 4"
of the cutterhead, lift it up and over the
cutterhead, and place it on the portion of
the workpiece that is over the outfeed table.
Now, focus your pressure on the outfeed end
of the workpiece while feeding, and repeat
the same action with your trailing hand when
it gets within 4" of the cutterhead. To keep
your hands safe, DO NOT let them get closer
than 4" from the cutterhead when it is mov-
ing! Failure to heed this warning could result
in serious personal injury.

To bevel cut on the jointer:
Bevel Cutting
1. Read and understand SECTION 1:
SAFETY.
The purpose of bevel cutting is to cut the edge of
a workpiece at a specific angle (see Figure 37).
2. Make sure your stock has been inspected
for dangerous conditions as described in the
Stock Inspection instructions.
The Model G0612 has fence stops you can set at
90˚, 45˚ inward, and 45˚ outward (135˚). If your
situation requires a different angle, the fence can
be locked anywhere between these angles.
3. Set the cutting depth for your operation. We

Schedule
Cleaning
For optimum performance from your machine,
follow this maintenance schedule and refer to any
specific instructions given in this section.
Cleaning the Model G0612 is easy and should
be done often. Vacuum excess wood chips and
sawdust, and wipe off the remaining dust away
with a dry cloth. If any resin has built up, use a
resin dissolving cleaner to remove it.
Daily Check
•
Vacuum all dust on and around the
machine.
Protect the unpainted cast iron surfaces on the
table by wiping the table clean after every use—
this will help prevent moisture from wood dust
accumulating on bare metal surfaces.
•
Empty debris from the dust collection bag.
DO NOT use the jointer if debis obstructs the
flow of material into the bag. Using the jointer
when the chute is obstructed can lead to
jointer malfuction and, possibly, fire. Failure
to heed this warning can result in serious
personal injury.
Keep tables rust-free with regular applications of
products like G96® Gun Treatment, SLIPIT®, or
Boeshield® T-9.
•
Wipe down tables and all other unpainted
cast iron with a metal protectant.
Lubrication
Monthly Check
All bearings are sealed and permanently lubri-
cated. Do not lubricate them; leave them alone
until they need to be replaced.
•

Note: When you remove the brush caps a
spring will pop out of the socket; the carbon
brush is firmly attached to this spring. When
you buy a new brush kit you will get a pair of
brush/spring assemblies.
Replacing Motor
Brushes
Your jointer has a single phase universal motor
that uses carbon brushes. Under normal opera-
tion these brushes wear out. Refer to the trouble-
shooting guide to determine if the motor brushes
must be replaced.
6. Check the brushes for wear. If a brush is
worn to less than 3/32" in length, replace both
brushes.
7. Insert the brush assemblies, positioning them
so they slide into the slots build into the sock-
ets.
You can order a new brush kit (two brush assem-
blies) from Grizzly. The part number for the brush
kit is P0612024-1.
8. Press the brush cap against the spring, push
it into the socket and turn the brush cap to
lock it in the motor housing.
Refer to the parts diagram in this manual when
replacing worn brushes. If you need assistance
call Grizzly Tech Support at (570) 546-9663.
9. Replace the motor cover and tighten the
Phillips screws.
To replace motor brushes:
10. Test run the jointer.
1. DISCONNECT THE JOINTER FROM THE
POWER SOURCE.
— If the jointer runs properly, you are done.
2. While facing the rear of the jointer, tip it away
from you until it rests on the fence assem-
bly.
— If the motor does not start, either the brush-
es are not correctly aligned in the sockets
or there is another problem with the motor
or wiring. Refer to the Troubleshooting
section for assistance.
3. Remove the four Phillips screws fastening
the motor cover to the jointer base. Lift the
cover and set it aside.
4. Take this opportunity to clear dust and debris
from inside the jointer.
