FUNCTIONAL DESCRIPTION
CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Shaft lock (Fig. 1)
CAUTION:
• 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 lever actuates properly and returns to the
"OFF" position when released.
• Do not pull the switch lever forcibly without pushing in
the lock-off lever.
For tool with lock button
To prevent the switch lever from accidentally pulled, a
lock-off lever is provided. To start the tool, pull the lock-off
lever toward the operator and then pull the switch lever.
Release the switch lever to stop. For continuous opera-
tion, pull the switch lever and then push in the lock but-
ton. To stop the tool from the locked position, pull the
switch lever fully, then release it.
For tool without lock button
To prevent the switch lever from accidentally pulled, a
lock-off lever is provided. To start the tool, pull the lock-off
lever toward the operator and then pull the switch lever.
Release the switch lever to stop.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing side grip (handle) (Fig. 3)
CAUTION:
• Always be sure that the side grip is installed securely
before operation.
Screw the side grip securely on the position of the tool as
shown in the figure.
Installing or removing wheel guard (Fig. 4 & 5)
CAUTION:
• The wheel guard must be fitted on the tool so that the
closed side of the guard always points toward the oper-
ator.
Mount the wheel guard with the protrusion on the wheel
guard band aligned with the notch on the bearing box.
Then rotate the wheel guard around 180 degrees. Be
sure to tighten the screw securely.
To remove wheel guard, follow the installation procedure
in reverse.

Installing or removing depressed center grinding
wheel/Multi-disc
WARNING:
• Always use supplied guard when depressed center
grinding wheel/Multi-disc is on tool. Wheel can shatter
during use and guard helps to reduce chances of per-
sonal injury.
Mount the inner flange onto the spindle. Fit the wheel/
disc on the inner flange and screw the lock nut onto the
spindle. (Fig. 6)
To tighten the lock nut, press the shaft lock firmly so that
the spindle cannot revolve, then use the lock nut wrench
and securely tighten clockwise.
To remove the wheel, follow the installation procedure in
reverse. (Fig. 7)
WARNING:
• Only actuate the shaft lock when the spindle is not
moving.
Installing or removing diamond wheel (optional
accessory) (Fig. 8 & 9)
CAUTION:
• Make sure that the arrow on the tool should point in the
same direction as the arrow on the diamond wheel.
Mount the inner flange onto the spindle. Fit the diamond
wheel on over the inner flange and screw the lock nut
onto the spindle. Notice that flat side of the lock nut
should face the diamond wheel in case the diamond
wheel is used.
OPERATION
WARNING:
• It should never be necessary to force the tool. The
weight of the tool applies adequate pressure. Forcing
and excessive pressure could cause dangerous wheel
breakage.
• ALWAYS replace wheel if tool is dropped while grind-
ing.
• NEVER bang or hit grinding disc or wheel onto work.
• Avoid bouncing and snagging the wheel, especially
when working corners, sharp edges etc. This can
cause loss of control and kickback.
• NEVER use tool with wood cutting blades and other
sawblades. Such blades when used on a grinder fre-
quently kick and cause loss of control leading to per-
sonal injury.
CAUTION:
• After operation, always switch off the tool and wait until
the wheel has come to a complete stop before putting
the tool down.
Grinding and sanding operation (Fig. 10)
ALWAYS hold the tool firmly with one hand on housing
and the other on the side handle. Turn the tool on and
then apply the wheel or disc to the workpiece.
In general, keep the edge of the wheel or disc at an angle
of about 15 degrees to the workpiece surface.
During the break-in period with a new wheel, do not work
the grinder in the B direction or it will cut into the work-
piece. Once the edge of the wheel has been rounded off
by use, the wheel may be worked in both A and B direc-
tion.
