13. Regularly clean the power tool's air vents. The
motor's fan will draw the dust inside the housing and
excessive accumulation of powdered metal may
cause electrical hazards.
14. Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
15. Do not use accessories that require liquid cool-
ants. Using water or other liquid coolants may result
in electrocution or shock.
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, backing pad, brush or any other acces-
sory. Pinching or snagging causes rapid stalling of the
rotating accessory which in turn causes the uncontrolled
power tool to be forced in the direction opposite of the
accessory's rotation at the point of the binding.
Kickback is the result of power tool misuse and/or incor-
rect operating procedures or conditions and can be
avoided by taking proper precautions as given below.
a) Maintain a firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. Always use auxiliary
handle, if provided, for maximum control
over kickback or torque reaction during start-
up. The operator can control torque reactions or
kickback forces, if proper precautions are taken.
b) Never place your hand near the rotating
accessory. Accessory may kickback over your
hand.
c) Do not position your body in the area where
power tool will move if kickback occurs. Kick-
back will propel the tool in direction opposite to
the wheel's movement at the point of snagging.
d) Use special care when working corners,
sharp edges etc. Avoid bouncing and snag-
ging the accessory. Corners, sharp edges or
bouncing have a tendency to snag the rotating
accessory and cause loss of control or kickback.
e) Do not attach a saw chain woodcarving blade
or toothed saw blade. Such blades create fre-
quent kickback and loss of control.
Safety Warnings Specific for Sanding Operations:
a) Do not use excessively oversized sanding
disc paper. Follow manufacturers recommen-
dations, when selecting sanding paper.
Larger sanding paper extending beyond the
sanding pad presents a laceration hazard and
may cause snagging, tearing of the disc or kick-
back.
Additional safety warnings:
16. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety
data.
17. Ventilate your work area adequately when you
perform sanding operations.
18. Use of this tool to sand some products, paints
and wood could expose user to dust containing
hazardous substances. Use appropriate respira-
tory protection.
19. Make sure the abrasive disc is not contacting the
workpiece before the switch is turned on.
20. Do not leave the tool running. Operate the tool
only when hand-held.
21. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
22. Check that the workpiece is properly supported.
23. If working place is extremely hot and humid, or
badly polluted by conductive dust, use a short-
circuit breaker (30 mA) to assure operator safety.
24. Do not use the tool on any materials containing
asbestos.
SAVE THESE INSTRUCTIONS.
WARNING:
DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to safety rules for the subject product. MISUSE or
failure to follow the safety rules stated in this instruc-
tion manual may cause serious personal injury.

FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.

• Never actuate the shaft lock when the spindle is mov-
ing. The tool may be damaged.
Press the shaft lock to prevent spindle rotation when
installing or removing accessories.
Switch action (Fig. 2)
CAUTION:
• Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to the
"OFF" position when released.
To start the tool, simply pull the switch trigger. Tool speed
is increased by increasing pressure on the switch trigger.
Release the switch trigger to stop.
For continuous operation, pull the switch trigger and then
push in the lock button.
To stop the tool from the locked position, pull the switch
trigger fully, then release it.
Speed adjusting dial (Fig. 3)
The rotating speed can be changed by turning the speed
adjusting dial to a given number setting from 1 to 6 (6 at
the time when the switch trigger is fully pulled).
Higher speed is obtained when the dial is turned in the
direction of number 6. And lower speed is obtained when
it is turned in the direction of number 1.
Refer to the table for the relationship between the number
settings on the dial and the approximate rotating speed.
