Installing side grip (handle) (Fig. 5)
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. 6)
CAUTION:
• When using a depressed center grinding wheel/Multi-
disc, flex wheel, wire wheel brush, cut-off wheel or
diamond wheel, the wheel guard must be fitted on the
tool so that the closed side of the guard always points
toward the operator.
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
personal 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. 7)
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. (Fig. 8)
To remove the wheel, follow the installation procedure in
reverse.
Installing or removing diamond wheel
(optional accessory) (Fig. 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.
WARNING:
• Only actuate the shaft lock when the spindle is not
moving.
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
grinding.
• 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
frequently kick and cause loss of control leading to
personal injury.
CAUTION:
• Make the depth of a single cut up to 5 mm. Adjust
pressure on the tool so that the tool does not slow
down during the operation.
• After operation, always switch off the tool and wait until
the wheel has come to a complete stop before putting
the tool down.
• If the tool is operated continuously until the battery
cartridge has discharged, allow the tool to rest for 15
minutes before proceeding with a fresh battery.
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
workpiece. Once the edge of the wheel has been rounded
off by use, the wheel may be worked in both A and B
direction.
Operation with diamond wheel
(accessory)
WARNING:
• Forcing and exerting excessive pressure or allowing
the wheel to bend, pinch or twist in the cut can cause
overheating of the motor and dangerous kickback of
the tool.
CAUTION:
• After cutting operation, make sure that the diamond
wheel stops revolving completely. Then, place the tool.
It is dangerous to place the tool before turning off the
tool. If there are dust or dirt around the tool, the tool
may suck in them.
Be sure that the wheel does not contact the workpiece.
Turn the tool on and hold the tool firmly. Wait until the
wheel attains full speed. Now simply move the tool
forward over the workpiece surface, keeping it flat and
advancing smoothly until the cutting is completed.
