Indication lamp with multi function
Fig.4
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)" position, the
indication lamp flickers quickly for approximately 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.

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.6
WARNING:
When using
•
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
procedure in reverse.
Installing or removing depressed center
grinding wheel/Multi-disc
Fig.7
WARNING:
Always use supplied guard when depressed
•
center grinding wheel/Multi-disc is on tool. Wheel

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.
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.

WARNING:
Only actuate the shaft lock when the spindle is not
moving.

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
•
grinding.
