4. Gradually lower pad to surface intended for sanding. Make sure
the machine is in motion while the pad is engaged with the surface
to be sanded. You may use broad circular motion as you sand
along the length of the surface or your may use a combination of
forward and sideward motions. In time you will develop your own
technique to optimize coverage and dust recovery. It is advisable
to not add effort to the pad as this may lead to “nosing in” or
“tipping” which produces grooves or lines on the surface.
5. When replacing abrasive, emptying the contents of the dust bag,
or sanding operation is completed, return machine to reclined
position, flip control switch to “OFF” then disconnect the motor
pigtail from the supply cable.
6. Empty dust bag whenever it becomes 1/3 full.
DANGER:
Failure to disconnect the supply cable from machine
whenever servicing, replacing abrasive, or emptying the dust bag could
result in electrocution or severe injury. Never leave machine unattended
while the supply cable is connected.
DANGER:
Never leave dust bag unattended with sanding dust
in it. Sanding dust can spontaneously ignite and cause a fire or explosion.
Empty dust bag into a metal container, clear of any combustibles. Do not
empty content into a fire. Do not overfill dust bag.

MACHINE SET-UP
Preparing the Machine for Operation
1. Familiarize yourself with the machine. Read all danger, warning, and caution
statements and the Owner’s Manual before operating this machine. If you or
your operator cannot read English, have this manual explained fully before
attempting to operate this machine.
2. Remove screw and abrasive retainer. Center abrasive on pad and secure with
abrasive retainer and screw. (Figure 3)
3. Return machine to upright position and tilt machine back on casters until it
comes to rest on the exhaust bracket. Machine will be in a reclined position.
Do not allow machine to rest on pad especially after use, or compression set
may take place within elastomer on pad. This will create a flat spot and bounce
during use. (Figure 4)
OPERATING INSTRUCTIONS
1. Move machine to the location of your work. Set any exposed nails with ham-
mer and punch to avoid encounter with abrasive.
WARNING:
Bodily injury could occur if power is applied to
the machine with the power switch already in the “ON” position. Always
check to assure that the power switch is in the “OFF” position before
applying power to the power cable.
2. Make sure the control switch is in the “Off” position then connect the supply
cable to an appropriately grounded fused circuit. Connect the supply cable to
the motor pigtail. (Figure 5)
3. With the machine in the reclined position firmly grasp both handles and flip the
control switch to the “ON” position. (Figure 4.)
4. Gradually lower pad to surface intended for sanding. Make sure the ma-
chine is in motion while the pad is engaged with the surface to be sanded.
You may use broad circular motion as you sand along the length of the
surface or your may use a combination of forward and sideward motions.
In time you will develop your own technique to optimize coverage and dust
recovery. It is advisable to not add effort to the pad as this may lead to “nos-
ing in” or “tipping” which produces grooves or lines on the surface.
5. When replacing abrasive, emptying the contents of the dust bag, or sanding
operation is completed, return machine to reclined position, flip control
switch to “Off” then disconnect the motor pigtail from the supply cable.
6. Empty dust bag whenever it becomes 1/3 full.

Head Conversion
Removing the Sanding Head
1. Make sure the control switch is in the “OFF” position and
disconnect the motor pigtail from the supply cable. (Figure 6)
2. With a Phillips screwdriver, remove the two screws “A”
securing the belt guard. Remove the belt guard. (Figure 4)
3. With a 7/16” socket, remove the four nuts “B” securing the
head attachment. (Figure 4)
4. Lift the head off of the machine, making sure the belt slips
over the motor pulley.
Installing the Sanding Head
1. Place the head on the machine, making sure the belt is
placed around the motor pulley. Position the belt in the lower-
most grooves, (closest to the motor), for the 8” extension.
Position the belt in the upper-most grooves, (furthest away
from the motor), for the 13” extension. (Figure 4)
2. Start all four nuts “B” by hand, but do not tighten.
3. Rotate pad driver “C” to make sure belt is in the appropriate
grooves.
CAUTION: Rapid belt wear will occur if belt is not properly
aligned.
4. Tension belt and tighten nuts “B” with a 7/16” socket.
NOTE: The tension should be great enough so that the belt
does not slip during use. Excessive tension will lessen bearing
and belt life.
5. Secure belt guard with screws “A”.
WARNING:
Bodily injury could occur if power is applied
to the machine with the power switch already in the “ON” position.
Always check to assure that the power switch is in the “OFF” position
before applying power to the power cable.
1. Move machine to the location of your work. Set any exposed
nails with hammer and punch to avoid encounter with
abrasive.
2. Make sure the control switch is in the “OFF” position then
connect the supply cable to an appropriately grounded fused
circuit. Connect the supply cable to the motor pigtail.
(Figure 6)
3. With the machine in the reclined position firmly grasp both
handles and flip the control switch to the “ON” position.

Adjustment Procedures
Routine Maintenance
Leveling
This machine can be leveled without tools. Grasp the adjusting screw, “A”,
and loosen the lock nut, “B”. (Figure 7).
Condition
- Pad creates ridges on both edges or a “hop” is experienced:
Rotate both adjusting screws equal amounts clockwise. Tighten locknuts
and test on a piece of plywood. Repeat procedure until condition is
corrected. We recommend you not exceed 1/8” rotation for each attempt.
Condition
- Pad creates a ridge on the tip of the pad: Rotate both adjusting
screws counter clockwise, tighten locknuts and test. Repeat procedure until
condition is corrected. Use only 1/8 rotation for each attempt.
Condition
- Pad creates a ridge on only one side of the pad: Either
rotate the adjusting screw of the side effected clockwise or rotate the
adjusting screw opposite counterclockwise, depending on whether the ridge
terminates beyond the tip of the pad or prior to it. If it is prior to the tip, adjust
the side effected, otherwise adjust the opposite side.
NOTE: If switching heads on the machine, it will need to be re-leveled.
CAUTION:
Failure to perform maintenance at recommended intervals may void warranty.
Carbon Brushes
Have the carbon brushes replaced at least every 500 hours and more frequently under heavy use.
Dust Bag
Periodically the dust bag should be turned inside out, shaken vigorously and machine washed in cold water to prevent pore blockage and loss of
dust control.
Bearings
To insure reliable performance, have armature and pad driver bearings inspected for wear or damage after every 1500 hours. If used heavily, have
the bearings replaced seasonally.
Belt
The belt should be inspected every 500 hours. Replace if there are cracks or signs of wear.
CAUTION:
Maintenance and repairs performed by unauthorized personnel could result in damage or injury. Maintenance and repairs
performed by unauthorized personnel will void your warranty. Failure to perform maintenance at recommended intervals may void warranty.
