Operation and Safety
Safety Practices:
Sanding dust is flammable!
Empty and clean dust bag
when not in use.
Always wear safety
goggles, protective
clothing, and a dust mask
while sanding.
Keep the dust bag
emptied. Dust generated
from sanding wood floors
can spontaneously ignite
or explode. Promptly
dispose of any sanding
dust in a metal container
clear of any combustibles.
Do not dispose in a fire.
Keep the work area well
ventilated.
Sanding/finishing wood
floors can create an
explosive or combustible
environment. Do not
operate this machine
around solvents, thinners,
fuels, floor finishes, or any
other flammable materials.
Keep hands, feet, and
loose clothing away from
all moving parts on the
machine.
Disconnect the power cord
before replacing the pad or
the abrasive.
Never leave the machine
unattended while it is
connected to a power
source.

Application: Wood flooring maintenance and light restoration work,
especially small projects that do not require a more aggressive tool.
This tool is well suited for use on parquet floors.
Set-up and operation
Follow the steps listed below to complete a floor sanding project safely.
Step Action
1
Prepare the room:
Step Action
1 Countersink any nails in the flooring.
2 Tape over electrical outlets.
3 Cover doorways and windows with plastic.
4 Cover all air vents in the room (intake and
output vents).
2
Attach sandpaper (36 grit)
to the buffing pad. The
adhesive backing on the
sandpaper sticks to the pad.
Be sure the power cord is
unplugged any time you are
changing sandpaper.
3
Connect the power cord to a 3-prong outlet. Always
make sure the ON/OFF switch (interlock) is in the OFF
position when connecting power.
4
Position the power cord safely out of the way of the
machine by looping a section of cord through a side belt
loop.
5
Release the handle by
pressing up on the locking
lever. Bring the handle to a
comfortable position. Do not
lock the handle. Locking
the handle will prevent the
machine from resting easily
on the pad.

Step Action
6
Start the sander:
Step Action
1 Stand directly behind the sander.
2 Grip one or both of the control levers securely.
3 Press the Interlock button.
4 When the motor starts, release the interlock, but
keep at least one of the control levers pressed
upward.
7
Slowly move the sander across the surface of the floor.
The pad will rotate quickly, so it is not necessary to move
with the grain of the wood as it is with the drum sander. The
square shape of the pad should allow you to cover the entire
floor, including the edges.
Note: Keep the sander in motion while the motor is
running to avoid damage and swirling.
8
When finished, release the control levers to stop the
machine.
Note: Empty the filter bag frequently to prevent a fire hazard.
Check the bag periodically to make sure it does not fill
up. Never leave the sander unattended without emptying
the bag first.
