Switch handle mounting positions

(For Models GA7030R, GA7040R, GA9030R and

GA9040R) (Fig. 2)

The switch handle can be rotated to either 90° left or right

to fit your work needs. First, unplug the tool. Press the

lock button and rotate the switch handle to left or right

fully. The switch handle will be locked in that position.

CAUTION:

• Always make sure that the switch handle is locked in

the desired position before operation.

Switch action (Fig. 3)

CAUTION:

• Before plugging in the tool, always check to see that

the switch trigger actuates properly and returns to the

“OFF” position when released.

For tool with the lock-on switch

To start the tool, simply pull the switch trigger (in the B

direction). Release the switch trigger to stop. For

continuous operation, pull the switch trigger (in the B

direction) and then push in the lock lever (in the A

direction). To stop the tool from the locked position, pull

the switch trigger fully (in the B direction), then release it.

For tool with the lock on and lock-off switch (Fig. 4)

To prevent the switch trigger from accidentally pulled, a

lock lever is provided.

To start the tool, push in the lock lever (in the A direction)

and then pull the switch trigger (in the B direction).

Release the switch trigger to stop.

For continuous operation, push in the lock lever (in the A

direction), pull the switch trigger (in the B direction) and

then pull the lock lever (in the C direction).

To stop the tool from the locked position, pull the switch

trigger fully (in the B direction), then release it.

Indication lamp (Fig. 5)

The indication lamp lights up green when the tool is

plugged. If the indication lamp does not light up, the mains

cord or the controller may be defective. The indication

lamp is lit but the tool does not start even if the tool is

switched on, the carbon brushes may be worn out, or the

controller, the motor or the ON/OFF switch may be

defective.

Unintentional restart proof

Even locking lever keeping the switch trigger depressed

(Lock-on position) does not allow the tool to restart even

when the tool is plugged.

At this time, the indication lamp flickers red and shows the

unintentional restart proof device is on function.

To cancel the unintentional restart proof, pull the switch

trigger fully, then release it.

Soft start feature

These models begin to run slowly when they are turned

on. This soft start feature assures smoother operation.

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. 6)

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. 7)

CAUTION:

• 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

counterclockwise. Be sure to tighten the screw securely.

To remove wheel guard, follow the installation procedure

in reverse.

Installing or removing wheel guard

(accessory) (Fig. 8 & 9)

CAUTION:

• The wheel guard must be fitted on the tool so that the

closed side of the guard always points toward the

operator.

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 figure. 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 to adjust the tightening 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)

(Fig. 10)

Mount the inner flange onto the spindle. Fit the wheel/disc

on the inner flange and screw the lock nut onto the

spindle.

Super flange

Models with the letter F are standard-equipped with a

super flange. Only 1/3 of efforts needed to undo lock nut,

compared with conventional type.

For Australia and New Zealand (Fig. 11)

Mount the inner flange onto the spindle. Fit the wheel/disc

on the inner flange and screw the lock nut with its

protrusion facing downward (facing toward the wheel).

(Fig. 12)

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.
