Automatic speed change function (Fig. 4)

015098

This tool has “high speed mode” and “high torque mode”. 
It automatically changes operation mode depending on 
the work load. When mode indicator lights up during 
operation, the tool is in high torque mode.

Tool/battery protection system

The tool is equipped with a tool/battery protection system. 
This system automatically cuts off power to the motor to 
extend tool and battery life.
The tool will automatically stop during operation if the tool 
or battery is placed under one of the following conditions. 
In some conditions, the indicator lights up.

Overload protection

When the tool is operated in a manner that causes it to 
draw an abnormally high current, the tool automatically 
stops without any indications. In this situation, turn the tool 
off and stop the application that caused the tool to 
become overloaded. Then turn the tool on to restart.

Overheat protection for tool

When the tool is overheated, the tool stops automatically 
and the battery indicator shows following state. In this 
situation, let the tool cool before turning the tool on again.

Releasing protection lock

When the protection system works repeatedly, the tool is 
locked and the battery indicator shows the following state.

015200

In this situation, the tool does not start even if turning the 
tool off and on. To release the protection lock, remove the 
battery, set it to the battery charger and wait until the 
charging finishes.

Shaft lock

 CAUTION:

• Never actuate the shaft lock when the spindle is 

moving. The tool may be damaged.

Press the shaft lock to prevent spindle rotation when 
installing or removing accessories.

ASSEMBLY

 CAUTION:

• Always be sure that the tool is switched off and the 

battery cartridge is removed before carrying out any 
work on the tool.

Installing side grip (handle)

Installing or removing wheel guard (For 
depressed center wheel, multi disc/
abrasive cut-off wheel, diamond wheel) 

 WARNING:

• 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.

• 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 clamp lever type wheel guard

Loosen the lever on the wheel guard after loosening the 
screw. 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 to such an angle that it 
can protect the operator according to work.

 (Fig. 7)

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 screw to adjust the tightening of the wheel 
guard band.

 (Fig. 8)

To remove wheel guard, follow the installation procedure 
in reverse.
