locations. Keep work area well lit. Don't expose power tools to rain. Don't use tool
in presence of flammable liquids or gases.
KEEP CHILDREN AWAY. All visitors should be kept away from work area. Don't
l e t visitors contact tool or extension cord.
STORE IDLE TOOLS. When not in use, tools should be stored in dry, and high or
locked-up place out of reach of children.
DON'T FORCE TOOL. It will do the job better and safer a t the rate for which it
was intended.
USE RIGHT TOOL. Don't force small tool or attachment to do the job of a heavyduty tool. Don't use tool for purpose not intended.
DRESS PROPERLY. Don't wear loose clothing or jewelry. They can be caught in
moving parts. Rubber gloves and non-skidfootwear are recommended when working
outdoors. Wear protective hair covering to contain long hair.
USE SAFETY GLASSES. Also use face or dust mask if cutting operation i s dusty.
DON'T ABUSE CORD. Never carry tool by cord or yank it to disconnect from receptacle. Keep cord from heat, oil, and sharp edges.
SECURE WORK. Use clamps or a vise to hold work. It's safer than using your hand
and it frees both hands to operate tool.
DON'T OVERREACH. Keep proper footing and balance at all times.
MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and safer
performance. Follow instructions for lubricating and charging accessories. Inspect
tool cords periodically and if damaged, have repaired by authorized service facility.
Keep handles dry, clean, and free from oil and grease.
DISCONNECT TOOLS. When not in use, before servicing, and when changing accessories, such as blades, bits, cutters.
REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see
that keys and adjusting wrenches are removed from tool before turning it on.
AVOID UNINTENTIONAL STARTING. Don't carry plugged-in tool with finger on
switch. Be sure switch is OFF when plugging in.
OUTDOOR USE EXTENTION CORDS. When tool is used outdoors, use only extension cords intended for use outdoors and so marked.
STAY ALERT. Watch what you are doing, use common sense. Don't operate tool
when you are tired.

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 i t s intended function. Check for alignment of moving parts, binding
of moving parts, breakage of parts, mounting, and other conditions that may affect
i t s operation. A guard or other part that is damaged should be properly repaired or
replaced by an authorized service center unless otherwise indicated elsewhere in this
instruction manual. Have defective switches replaced by authorized service center.
Don't use tool if switch does not turn it on and off.
19. GUARD AGAINST ELECTRIC SHOCK. Prevent body c o n t a c t with grounded sur-

faces. For example; pipes, radiators, ranges, refrigerator enclosures.

20. REPLACEMENT PARTS. When servicing, use only identical replacement parts.
SAVE THESE INSTRUCTIONS.
VOLTAGE WARNING: Before connecting the tool to a power source (receptacle. outlet, etc.1 be sure
the voltage supplied is the same as that specified on the nameplate of the tool. A power source with
voltage greater than that specified for the tool can result in SERIOUS INJURY to the user - as well as
damage to the tool. If in doubt, DO NOT PLUG IN THE TOOL. Using a power source with voltage
less than the nameplate rating is harmful to the motor.

How to use
Attaching sandpaper
To replace the sandpaper, pull back on
the lever clip to release the paper clamp
below. (Dustproof frame cover must first
be removed. Insert the paper between the
base and the paper clamp, bending a portion of about 20 mm (3/4")on both ends
to make entry easier. Then make sure
that the paper i s snugly fit to the pad
with the right tension. Failure to have it
on tight will cause the paper to rip or
mark the sanding surface.
Switch
There i s a slide switch on the upper side of the tool handle. Press it forward to put the
tool on; slip it backward to put the tool off.
Sanding
Lightly press the tool in such a manner that the entire pad surface contact uniformly
the surface to be sanded. Excessive pressure on the tool or one-sided pressure may produce uneven surface, cause damage to the abrasive paper and shorten tool life.
Do not allow the pad (without abrasive paper) to contact works surface or it will be
damaged, lessening i t s life.

Dust bag attachment
To install the dust bag, fit the bag's
entry port onto the dust chute on the
right side of the sander, then see that the
small hole on the port fits over the pin
protruding from the chute by turning left
or right.
When removing the dust bag, turn the bag
to the left t o slip the hole off the pin,
then simply pull off the dust bag.

Removing the frame cover
Remove from either the front or back as
shown, when taking off the frame cover.
0

Regular emptying of dust bag
Regular emptying of the dust bag insures
the maximum suction force. A full bag
makes for ineffective dust collection.
Operation with coolant
This tool can be used to sand with waterproof paper and a coolant, but coolant should
never be allowed to enter the motor area. To use coolant, first remove the dust bag and
clean off any dust adhering to the tool. Do a dry run for 2 or 3 minutes with the tool
held off the surface in order to remove dust adhering to the dust chute area. Then use
only enough coolant to give good operation as excessive coolant can easily be splashed
into the motor and markedly shorten motor life. Coolant may also bridge parts which
could result in a shock hazard.

commercial abrasive paper of the size
228 mm (9") x 280 mm (11-1/16"1 may
be used by cutting it in half.
