NOTE:
The overheat protection works only with a battery
cartridge with a star mark.
Fig.2
Indication lamp with multi function
Fig.3
Indication lamps are located in two positions.
When the battery cartridge is inserted on the tool with
the slide switch positioned in the "O (OFF)", the
indication lamp flickers quickly for approximately one
second. If it does not flicker so, the battery cartridge or
indication lamp may be broken.
−
Overload protection
−
When the tool becomes 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 situation, move the slide switch to the
"O (OFF)" position once. And then move it to
the "I (ON)" position again to restart.
−
Battery cartridge replacing signal
−
When the remaining battery capacity is low,
the indicator lamp lights up during operation
earlier than that of high battery capacity.
−
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. In this
situation, the lamp flickers slowly. It indicates
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.
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.
Switch action
Fig.5
CAUTION:
•
Before inserting the battery cartridge into the tool,
always check to see that the slide switch actuates
properly and returns to the "OFF" position when
the rear of the slide switch is depressed.
To start the tool, slide the slide switch toward the "I
(ON)" position. For continuous operation, press the front
of the slide switch to lock it.
To stop the tool, press the rear of the slide switch, then
slide it toward the "O (OFF)" position.
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)
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
(For depressed center wheel, multi disc /
abrasive cut-off wheel, diamond wheel)
For tool with locking screw type wheel guard
Fig.7
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 European
countries, when using a diamond wheel, the
ordinary guard can be used.)
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. 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
Fig.8
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.
