WARNING
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains
chemicals known to the State of California to cause
cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement, and
other masonry products.
• Arsenic and chromium from chemically treated
lumber.
Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated
area, and work with approved safety equipment, such
as those dust masks that are specially designed to filter out microscopic particles.

9. USE PROPER EXTENSION CORD. Make
sure your extension cord is in good condition. Conductor size should be in accordance with the chart below. The amperage
rating should be listed on the motor or tool
nameplate. An undersized cord will cause
a drop in line voltage resulting in loss of
power and overheating. Your extension
cord must also contain a ground wire and
plug pin. Always repair or replace extension cords if they become damaged.
Minimum Gauge for Extension Cords
10. WEAR PROPER APPAREL. DO NOT
wear loose clothing, gloves, neckties,
rings, bracelets, or other jewelry which may
get caught in moving parts. Non-slip
footwear is recommended. Wear protective
hair covering to contain long hair.
11. ALWAYS USE SAFETY GLASSES. Also
use face or dust mask if cutting operation is
dusty. Everyday eyeglasses only have impact
resistant lenses, they are NOT safety glasses.
12. SECURE WORK. Use clamps or a vise to hold
work when practical. It’s safer than using your
hand and frees both hands to operate tool.
13. DO NOT OVER-REACH. Keep proper
footing and balance at all times.
14. MAINTAIN TOOLS WITH CARE. Keep
tools sharp and clean for best and safest
performance. Follow instructions for lubricating and changing accessories.

Safety Instructions For Power Tools
15. USE RECOMMENDED ACCESSORIES.
Consult the owner’s manual for recommended accessories. The use of improper
accessories may cause risk of injury.
16. REDUCE THE RISK OF UNINTENTIONAL STARTING. On machines with magnet-
ic contact starting switches there is a risk of
starting if the machine is bumped or jarred.
Always disconnect from power source
before adjusting or servicing. Make sure
switch is in OFF position before reconnecting.
17. CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part
that is damaged should be carefully
checked to determine that it will operate
properly and perform its intended function.
Check for alignment of moving parts, binding of moving parts, breakage of parts,
mounting, and any other conditions that
may affect its operation. A guard or other
part that is damaged should be properly
repaired or replaced.
18. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. DO NOT
leave tool until it comes to a complete stop.
19. NEVER OPERATE A MACHINE WHEN
TIRED, OR UNDER THE INFLUENCE OF
DRUGS OR ALCOHOL. Full mental alert-
ness is required at all times when running a
machine.
20. NEVER ALLOW UNSUPERVISED OR
UNTRAINED PERSONNEL TO OPERATE THE MACHINE. Make sure any
instructions you give in regards to machine
operation are approved, correct, safe, and
clearly understood.
21. IF AT ANY TIME YOU ARE EXPERIENCING DIFFICULTIES performing the intend-
ed operation, stop using the machine! Then
contact our service department or ask a
qualified expert how the operation should
be performed.
G0526 6" Jointer -5-
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 personal injury, damage to equipment, or poor
work results.
Like all machines there is danger associated
with the Model G0526. Accidents are frequently caused by lack of familiarity or failure to pay attention. Use this machine with
respect and caution to lessen the possibility
of operator injury. If normal safety precautions are overlooked or ignored, serious
personal injury may occur.
Additional Safety Instructions For Jointers
1. JOINTING SAFETY BEGINS with your
lumber. Inspect your stock carefully before
you feed it over the cutterhead. If you have
any doubts about the stability or structural
integrity of your stock, DO NOT JOINT IT!
2. MAINTAIN PROPER RELATIONSHIPS of
infeed and outfeed table surfaces and cutterhead knife path.
3. ALWAYS USE A PUSH PADDLE when
jointing. Never place your hands directly
over the cutterhead.
4. SUPPORT THE WORKPIECE adequately
at all times during operation, and maintain
control over the work at all times.
5. WHEN JOINTING, DO NOT stand directly
at the end of either table. Position yourself
just to the side of the infeed table to protect
yourself from possible kickbacks.
6. NEVER MAKE JOINTING CUTS deeper
than
1
⁄8".
7. NEVER JOINT A BOARD that has loose
knots. All defects should be cut out of the
board before it is planed or jointed.
8. NEVER JOINT end grain.
9. JOINT WITH THE GRAIN. Jointing against
the grain is dangerous and could produce
chatter or excessive chip out , which could
lead to loss of control over the workpiece.
10. WITH THE EXCEPTION OF RABBETING,
all operations must be performed with the
guard in place. After rabbeting, be sure to
replace the guard.
11. NEVER BACK THE WORK toward the
infeed table. If a cut must be interrupted, lift
the workpiece clear of the cutterhead.
12. HABITS — GOOD AND BAD — are hard
to break. Develop good habits in your shop
and safety will become second-nature to
you.
13. “KICKBACK” is when the workpiece is
thrown off the jointer table by the force of
the cutterhead. Always use push paddles
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.
14. PROLONGED EXPOSURE TO WOOD
DUST IS KNOWN TO CAUSE CANCER IN
HUMANS. Always wear an OSHA-
approved respirator when working in an
environment that could contain wood dust.

Commentary
SECTION 2: INTRODUCTION
G0526 6" Jointer -7-
The Model G0526 features a 110V/220V motor
that is prewired at 110V.
Amperage Draw
110V (prewired) .................................... 18 Amps
220V ...................................................... 9 Amps
Use the following guidelines when choosing a circuit breaker (circuit breakers rated any higher are
not adequate to protect the circuit):
Circuit Breaker
110V (prewired) ..........................20 Amp, 1 Pole
220V ..........................................10 Amp, 2 Pole
Figure 1b. NEMA 6-15 plug and receptacle.
Figure 1a. NEMA 5-15 plug and receptacle.
The cord set enclosed is equipped with a NEMA
5-15 plug (Figure 1a).
If the jointer is rewired to operate on a 220V
power source, the plug must be replaced with a
NEMA 6-15 plug (Figure 1b).

SECTION 3: CIRCUIT REQUIREMENTS
-8-
G0526 6" Jointer
Electrocution or a fire
can result if the machine
is not grounded correctly. Make sure all electrical circuits are grounded. DO NOT use the
machine if it is not
grounded.
Because of the high amperage draw from this
machine, we do not recommend the use of extension cords. Instead, position your equipment near
installed wiring to eliminate the need for extension cords.
NOTICE
The wire on the power cord with green or
green and yellow striped insulation is the
grounding conductor.
In the event of an electrical short, grounding
reduces the risk of electric shock by providing a
path of least resistance to disperse electric current. This tool is equipped with a power cord that
has an equipment-grounding prong. The outlet
must be properly installed and grounded in accordance with all local codes and ordinances.
The Model G0526 can be rewired to operate on a
220V power source; however, the MA-15
Magnetic Overload Switch (18-26A) must be
replaced with an MA-9 Magnetic Overload Switch
(8-12A). To order the MA-9, call our customer
service number at (800) 523-4777 and purchase
part #
P0526349.
The motor must also be rewired to handle the
220V power source. The correct wiring configuration can be found on the inside of the motor wire
cover, as well as on page 48.
This procedure takes moderate electrical skill and
the rewiring job should be inspected by a licensed
electrician before turning the machine ON.
Extension CordsCircuit Capacity
Grounding
Rewiring To 220V
Always check to see if the wires in your circuit are
capable of handling the amperage draw from
your machine, as well as any other machines that
could be operating on the same circuit. If you are
unsure, consult a qualified electrician.
If the circuit breaker trips or the fuse blows regularly, your machine may be operating on a circuit
that is close to its amperage draw capacity.
However, if an unusual amperage draw does not
exist and a power failure still occurs, contact a
qualified electrician.

Infeed Table: The infeed table is where the cut-
ting operation begins. When facing the front of
the jointer, it is on the right-hand side. The
wood travels right to left; from the infeed table,
across the cutterhead, and onto the outfeed
table.
Outfeed Table: The outfeed table is where the
cutting operation ends. When facing the front
of the jointer, it is on the left-hand side.
Cutterhead: The cutterhead is the cylindrical
assembly that holds each of the carbide cutters. It spins on a horizontal axis between the
infeed and outfeed table, and is covered by the
cutterhead guard.
Fence: The jointer fence is the adjustable cast
iron surface that the wood stock runs along
when jointing and surface planing. The fence is
adjustable from 45°-90° to the infeed and outfeed tables.
Adjustment Handwheels: Controls the height of
the infeed and outfeed tables.
Table Lock Handles: The threaded handles that
must be loosened before the height of the
tables can be adjusted. They are then tightened after the height is properly set.
Rabbet Cut: A rabbet cut is a groove cut along
the long edge of the wood stock, usually used
for making simple joints. The cutterhead guard
must be removed for this operation, so great
care is needed for safe operation.
Surface Planing: Surface planing is running the
face of the wood stock over the jointer. This
provides one flat side that is ready to be run
through a dedicated planing machine.
Edge Jointing: Edge jointing is running the long
edge of the wood stock over the jointer. This
provides one flat edge that is ready to be run
against the table saw rip fence or edge glued.
Cutterhead Guard: The metal guard that covers
the cutterhead and automatically moves out of
the way during operation, then automatically
moves back into place after the operation.
