Electronic function
The tools equipped with electronic function are easy to
operate because of the following features.
Constant speed control
Possible to get fine finish, because the rotating speed is
kept constant even under loaded condition.
Additionally, when the load on the tool exceeds admissi-
ble levels, power to the motor is reduced to protect the
motor from overheating. When the load returns to admis-
sible levels, the tool will operate as normal.
Soft start feature
Soft start because of suppressed starting shock.
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 (For
depressed center wheel, multi disc, wire wheel
brush / abrasive cut-off wheel, diamond wheel)
WARNING:
• When using a depressed center grinding wheel/Multi-
disc, flex wheel or wire wheel brush, the wheel guard
must be fitted on the tool so that the closed side of the
guard always points toward the operator.
• When using an abrasive cut-off / diamond wheel, be
sure to use only the special wheel guard designed for
use with cut-off wheels. (In some European countries,
when using a diamond wheel, the ordinary guard can
be used. Follow the regulations in your country.)

For tool with locking screw type wheel guard (Fig. 4)
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 coun-
terclockwise. Be sure to tighten the screw securely.
To remove wheel guard, follow the installation procedure
in reverse.
For tool with clamp lever type wheel guard
(Fig. 5 & 6)
Loosen the lever on the wheel guard. 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 to the position shown in the fig-
ure. Tighten the lever to fasten the wheel guard. If the
lever is too tight or too loose to fasten the wheel guard,
loosen or tighten the nut by spanner to adjust the tighten-
ing of the wheel guard band.
To remove wheel guard, follow the installation procedure
in reverse.
Installing or removing depressed center grinding
wheel/Multi-disc (accessory)
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.
To remove the wheel, follow the installation procedure in
reverse. (Fig. 8)
Super flange
Models GA7010CF and GA9010CF are standard-
equipped with a super flange. Only 1/3 of efforts needed
to undo lock nut, compared with conventional type.
Installing or removing abrasive disc (optional
accessory) (Fig. 9)
NOTE:
• Use sander accessories specified in this manual.
These must be purchased separately.
Mount the rubber pad onto the spindle. Fit the disc on the
rubber pad and screw the lock nut onto the spindle. 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 disc, follow the installation procedure in
reverse.

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.
