DANGER: Sanding/finishing wood floors can create an environment that can be explosive. The
following safety procedures must be adhered to:
• Cigarette lighters, pilot lights and any other source of ignition can create an explosion
when active during a sanding session. All sources of ignition should be extinguished or
removed entirely if possible from the work area.
• Work areas that are poorly ventilated can create an explosive environment when certain
combustible materials are in the atmosphere, i.e., solvents, thinners, alcohol, fuels,
certain finishes, wood dust and other combustible materials. Floor sanding machines
can cause flammable material and vapors to burn. Read the manufacturer's label on all
chemicals used to determine combustibility. Keep the work area well ventilated.
• Spontaneous combustion or an explosion can occur when working with sanding dust.
The sanding dust can ignite and cause injury or damage. Sanding dust should be
disposed of properly. Always empty the sanding dust into a metal container that is
located outside of any building(s).
• Remove the contents of the dust bag when the bag is 1/3 full. Remove the contents of
the dust bag each time you finish using the machine. Never leave a dust bag unattended
with sanding dust in it.
• Do not empty the contents of the dust bag into a fire.
• Hitting a nail while sanding can cause sparks and create an explosion or fire. Always
use a hammer and punch to countersink all nails before sanding floors.

SANDING CUTS AND SANDPAPER
Initial Cut
The purpose of the initial cut is to remove old finish and gross imperfections on the floor surface. A coarse
abrasive should be used.
If glazing, loading, or burning takes place immediately into an initial cut, select a coarser abrasive. If this
should occur during an initial cut, the abrasive has dulled and must be replaced.
Final Cuts
The purpose of a finishing cut is to remove the scratches produced during the initial cut. Use a fine (60 - 80
grit) grain abrasive.
If the surface remains rough after a finishing cut, it may be necessary to use an even finer grain of abrasive (80
- 100 grit). Care should be taken in selecting the grit size of the abrasive. A very fine grain will close the
pores on a wood floor making admission of a stain difficult.

MACHINE SET-UP
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. Install dust bag support to the exhaust bracket (figure 1).
Place opening of dust bag over dust bag support and
exhaust bracket; cinch and tie securely to exhaust bracket.
3. Remove screw and abrasive retainer. Center abrasive on
pad and secure with abrasive retainer and screw. (Figure
2)
4. 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 ma-
chine 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 3)
OPERATING INSTRUCTIONS
1. Move machine to the location of your work. Set any
exposed nails with hammer 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 4)
3. With the machine in the reclined position firmly grasp both
handles and flip the control switch to the "ON" position.
(Figure 3.)
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.

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.
Lubrication
The machine comes fully lubricated. The gears in
the gear box have enough lubrication for approxi-
mately six months of normal operation. Have the
lubricant changed at least every 6 months or more
frequently under heavy use.
OPERATING INSTRUCTIONS cont.
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 combus
tibles. Do not empty content into a fire.
Do not overfill dust bag.
ADJUSTMENT PROCEDURES
Leveling
To level machine: Grasp caster adjusting screw "A" with an
appropriate tool (pliers ect.). Using a similar tool, loosen
locknut "B" with a counter clockwise motion. (Figure 5).
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 ply-
wood. 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 theadjusting screw opposite counter-
clockwise, 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.
ROUTINE MAINTENANCE
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.
