Manual Before Operating Power Feeder
Safety Instructions For Power Tools
These safety rules cannot cover every situation in a workshop. Consider your conditions when setting up
or operating your power feeder.
SECTION 1: SAFETY
a) Always wear eye protection.
b) Always keep guards in place and in proper
operating condition.
c) The power feeder must be fixed rigid to the
your power tool.
d) Support the workpiece adequately at all
times during operation; maintain control of
the work at all times.
e) Do not attempt to perform an abnormal or
little-used operation without study and the
use of adequate hold-downs, jigs, fixtures,
stops, and the like.
9. USE PROPER EXTENSION CORD. Make
sure your extension cord is in good condition.
When using an extension cord, be sure it is
rated Hard Service (grade S) or better.
Conductor size must be 14 A.W.G. for cords
up to 50 feet in length. 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.
10. WEAR PROPER APPAREL Do not wear
loose clothing, gloves, neckties, rings,
bracelets, or other jewelry which may get
caught in moving parts. Nonslip 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.
1. KEEP GUARDS IN PLACE and in working
order.
2. REMOVE ADJUSTING KEYS AND
WRENCHES. Form habit of checking to see
that keys and adjusting wrenches are
removed from tool before turning on.
3. KEEP WORK AREA CLEAN. Cluttered
areas and benches invite accidents.
4. DON’T USE IN DANGEROUS ENVIRONMENT. Don’t use power tools in damp or
wet locations, or expose them to rain. Keep
work area well lighted.
5. KEEP CHILDREN AWAY. All visitors
should be kept a safe distance from work
area.
6. MAKE WORKSHOP KID PROOF with pad-
locks, master switches, or by removing
starter keys.
7. DON’T FORCE TOOL. It will do the job bet-
ter and safer at the rate for which it was
designed.
8. USE RIGHT TOOL. Don’t force tool or
attachment to do a job for which it was not
designed.

Additional Safety Instructions For Power Feeders
18. 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 alignment of moving parts, binding of moving
parts, breakage of parts and any other conditions that may affect its operation. A guard or
other part that is damaged should be properly repaired or replaced.
19. DIRECTION OF FEED. Feed work into a
blade or cutter against the direction of rotation of the blade or cutter only.
20. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don’t leave
tool until it comes to a complete stop.
5. Replace wheels when they become worn or
disfigured.
6. Do not stand directly in front of or in back of
the workpiece as it is feeding through your
power tool. Stand to one side.
7. Extension cords , if used, must be rated Hard
Service (grade S) or better. Conductor size
must be 14 A.W.G. for cords up to 50 feet in
length. Your extension cord must also contain a ground wire and plug pin. Always
repair or replace extension cords if they
become damaged.
8. Habits – good and bad – are hard to break.
Develop good habits in your shop and safety will become second-nature to you.
1. Inspect your stock carefully before you feed
it through the machine. If you have any
doubts about the stability or structural
integrity of your stock, DO NOT USE IT!
2. Never mill stock that has loose knots. All
defects should be cut out of the board before
it is processed.
3. DO NOT jam workpiece into the wheels.
Firmly grasp the workpiece in both hands
and ease it into the rotating wheels. Guide
the workpiece to ensure that it properly contacts the cutterhead or blade.
4. DO NOT place hands near, or in contact with
moving wheels. DO NOT place hands near
any spinning blades or cutterheads.
13. DON’T OVERREACH. 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.
15. DISCONNECT TOOLS before servicing and
changing accessories, such as blades, bits,
cutters, and the like.
16. REDUCE THE RISK OF UNINTENTIONAL
STARTING. Make sure switch is in off posi-
tion before plugging in.
17. USE RECOMMENDED ACCESSORIES.
Consult the owner’s manual for recommended accessories. The use of improper accessories may cause risk of injury to persons.

Figure 1. Recommended receptacle.
220V Operation
The G1128 and G1129 is supplied with a 220V
only motor. The
1
⁄2 HP motor on the G1128 will
draw roughly 4 amps. The 1 HP motor on the
G1129 will draw about 3.5 amps. These loads are
not excessive, but if you operate your machine on
any circuit that is already close to capacity, it
might blow a fuse or trip a circuit breaker. If an
unusual load does not exist and power failure still
occurs, consult a qualified electrician. Otherwise,
consider a dedicated circuit for your machine. A
15 amp circuit breaker or fuse should be used for
a 220V undedicated circuit. The general rule is to
use the lightest breaker or fuse that will hold
under regular loads. Circuit breakers or fuses that
are rated higher may not adequately protect the
motor.
You must provide your own plug with both power
feeders. Figure 1. Ensure that the plug type
matches the outlet you intend to use. Connect the
plug to the power cord per the plug instructions.
Ensure that the ground wire is connected to the
plug.
Grounding
CAUTION: THIS TOOL MUST BE GROUNDED
WHILE IN USE TO PROTECT THE OPERATOR
FROM ELECTRIC SHOCK.
In the event of an electrical short, grounding provides a path of least resistance for electric current
to reduce the risk of electric shock. This tool is
equipped with an electric cord having an equipment-grounding conductor. The plug must be
plugged into a matching outlet that is properly
installed and grounded in accordance with all
local codes and ordinances.
Improper connections of the electrical-grounding
conductor can result in risk of electric shock. The
conductor with green or green and yellow striped
insulation is the electrical-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.
Under no circumstances should the grounding
pin from any plug be removed. If it will not fit the
outlet, have the proper outlet installed by a qualified electrician.
Check with a qualified electrician or one of our
service personnel if the grounding instructions
are not completely understood, or if in doubt as to
whether the tool is properly grounded.
Be sure that your particular electrical configuration complies with local and state codes. The best
way to ensure compliance is to check with your
local municipality or licensed electrician.
Repair or replace damaged or worn cord immediately.

To operate this or any power tool safely and efficiently, it is essential to become as familiar with it
as possible. The time you invest before you begin
to use your Model G1128/G1129 will be time well
spent. DO NOT operate this machine until you
are completely familiar with the contents of this
manual.

Unpacking
The G1128 Power Feeder is shipped from the
factory in a carefully packed carton. The G1129 is
shipped in two cartons. If you find the machine to
be damaged after you’ve signed for delivery and
the truck and driver are already gone, you will
need to file a freight claim with the carrier. Save
the containers and all packing materials for
inspection by the carrier or their agent. Without
the packing materials, filing a freight claim can be
difficult. If you need advice regarding this situation, please call us.
Caution: The G1128 and G1129 are relatively
heavy machines (105 lbs. and 152 lbs. respective
shipping weights). DO NOT over-exert yourself
while unpacking or moving your machine – get
assistance.
When you are completely satisfied with the condition of your shipment, you should inventory its
parts.
Piece Inventory
After all the parts have been removed from the
carton, you should have:
G1128:
• Power Feeder Motor/Wheels
• Pivot Joint Assembly
• Horizontal/Vertical Column Assembly
w/Base
• Gears (2)
•Wheel Handles (2)
G1129:
• Power Feeder Motor/Wheels
• Pivot Joint Assembly
• Vertical Column Assembly w/Base
• Horizontal Column
•Wheel Handles (2)
• Grease Gun
In the event that any non-proprietary parts are
missing (e.g. a nut or a washer...), we would be
glad to replace them, or, for the sake of expediency, replacements can be obtained at your local
hardware store.
G1128/G1129 Power Feeders -7-
Clean up
The columns and other unpainted parts of the
Model G1128/G1129 are coated with a waxy oil
that protects them from corrosion during shipment. Remove the protective coating with mineral spirits and paper towels. Do not use gasoline or
other petroleum based solvents because of their
extremely low flash points. Do not use chlorinebased solvents – if you happen to splash some
onto a painted surface, you’ll ruin the finish.
WARNING!
Follow the safety rules listed below when
working with solvents:
1. Read and follow all directions and warnings
on the solvent label.
2. Work only in a well ventilated area.
3. Do not work near any type of open flame
(e.g., pilot lights, kerosene heaters, and so
on).
4. DO NOT smoke while working with flamma-
ble material.
5. Paper towels from the cleaning process are
extremely combustible. Dispose of waste
towels so they do not create a fire hazard.
Site Considerations
1. Working Clearances: Consider existing and
anticipated needs, size of material to be
processed through each machine, and
space for auxiliary stands, work tables or
other machinery when establishing a location for your power feeder.
2. Lighting and Outlets: Lighting should be
bright enough to eliminate shadow and prevent eye strain. Electrical circuits should be
dedicated or large enough to handle amperage requirements. Outlets should be located
near each machine so power or extension
cords are clear of high-traffic areas. Observe
local electrical codes for proper installation
of new lighting, outlets, or circuits.

WARNING: DO NOT ATTEMPT TO OPERATE
THE POWER FEEDER UNTIL IT IS PERMANENTLY MOUNTED TO THE TABLE TOP!
MOUNTING THE POWER FEEDER TO YOUR
MACHINE WILL MAKE IT TOP HEAVY.
SECURELY ATTACH YOUR MACHINE TO THE
FLOOR OF YOUR SHOP.
6. Use the base as your template and mark the
outside perimeter of the base and the loca-
tions of the four bolt holes on your table.
7. Measure the distances of the four mounting
holes from the edges of the table with an
accurate ruler. Compare those measurements with the bottom of the table. Ensure
that the mounting holes will not be over the
cast braces on the underside of the table.
8. Drill
3
⁄8" diameter holes through your table.
Use
5
⁄16" through bolts of sufficient length with
flat and lock washers to attach the base.
They will provide added support.
9. Re-insert the shaft assembly into the base.
Orient the horizontal shaft properly. Tighten
the lock handle.
G1129 ONLY: Tighten the cap screw on the
base to inhibit spinning of the vertical shaft.
10. Mount the motor/wheel assembly to the
pivot joint assembly.
G1128: Screw the lower lock handle into the
hole on the wheel housing.
G1129: Remove the handle and screw from
the motor clamp assembly (MCA). Place
the outer half of the MCA off to one side.
Position the motor/wheel assembly so the
MCA clamps around the bottom of the motor.
Replace the outer half of the MCA. Tighten
securely with the handle and screw.
SECTION 4: ASSEMBLY
Most of your G1128/G1129 Power Feeder has
been assembled at the factory, but some parts
must be assembled or installed after delivery. We
have organized the assembly process into steps.
Please follow along in the order presented here.
Note: Read Section 4 in its entirety before begin-
ning assembly.
1. (Step 1 for G1129 only) Insert the horizontal
shaft through the shaft coupler. The gear
rack on the horizontal shaft should engage.
2. Turn the distance adjustment wheel so that
the shaft coupler is approximately centered
on the horizontal shaft. Turn the height
adjustment wheel so that the shaft coupler
is approximately centered on the vertical
shaft.
3. Attach the pivot joint assembly to the end
of the horizontal shaft. Secure with the
locking handle.
4. Remove the base by loosening the lock
handle. Set the shaft assembly to the side.
5. Find the best mounting location on your
woodworking machine. Guidelines:
a. The power feeder should not affect any
moving machine parts.
b. It should be as close to the work area as
possible, i.e., keep the distance between the
base and rollers to a minimum.
c. Test the location by temporarily mounting
the base on a stable piece of hardwood
which is clamped to the machine. Swing the
power feeder in a variety of positions to
ensure that the base is best suited to your
anticipated needs.

Roller Placement
SECTION 5: ADJUSTMENTS
Your power feeder will operate best if the rollers
are properly placed and their speed is correct for
the job.
G1129: If you look at the rollers on the G1129,
you will notice that the gap between the first
and second rollers is larger than that
between the second and third rollers. This
arrangement allows you to place the rollers
so the first wheel is slightly ahead of your
cutting tool, while the middle and third
wheels are behind. Thus, the rollers feed
your workpiece into, through and past the
cutting surface smoothly. This feature provides consistent application of force without
binding the cutting tool.
G1128: The G1128 does not have different sized
gaps between the wheels. However, the
first wheel must be placed slightly ahead of
the cutter for the power feeder to work
effectively.
To position the rollers correctly on the G1128
/ G1129:
1. Raise the horizontal column so the rollers
are just above the table.
2. Swing the motor and roller assembly so the
rollers are just slightly away from the cutter,
with the first roller slightly forward of the cutting region.
3. Skew the feed rollers so they are angled just
slightly toward the fence. The first wheel
should be just about
1
⁄8" - 3⁄16" closer to the
fence than the third wheel. Figure 3.
