Indication lamp with multi function
007224
Indication lamps are located in two positions.
When the battery cartridge is inserted on the tool with the slide switch posi-
tioned in the "O (OFF)" position, the indication lamp flickers quickly for approx-
imately one second. If it does not flicker so, the battery cartridge or indication
lamp has broken.
- Overload protection
- When the tool is overloaded, the indication lamp lights up. When the
load on the tool is reduced, the lamp goes out.
- If the tool continues to be overloaded and the indication lamp
continues to light up for approximately two seconds, the tool stops.
This prevents the motor and its related parts from being damaged.
- In this case, to start the tool again, move the slide switch to the "O
(OFF)" position once and then to the "I (ON)" position.
- Battery cartridge replacing signal
- When the remaining battery capacity gets small, the indicator lamp
lights up during operation earlier than enough capacity battery use.
- Accidental re-start preventive function
- Even if the battery cartridge is inserted on the tool with the slide
switch in the "I (ON)" position, the tool does not start. At this time, the
lamp flickers slowly and this shows that the accidental re-start
preventive function is at work.
- To start the tool, first slide the slide switch toward the "O (OFF)"
position and then slide it toward the "I (ON)" position.
CAUTION:
• Always be sure that the tool is switched off and the battery cartridge is
removed before carrying out any work on the tool.

CAUTION:
• Always be sure that the side grip is installed securely before operation.

Installing or removing wheel guard
007218
1
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
2
be fitted on the tool so that the closed side of the guard always points
3
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.
