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 indi-
cation 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 indica-
tion 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.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before carrying out any work
on the tool.
Installing side grip (handle) (Fig. 5)
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. 6)
CAUTION:
• When using a depressed center grinding wheel/Multi-
disc, flex wheel, wire wheel brush, cut-off wheel or dia-
mond wheel, 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. 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
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 per-
sonal injury.
Mount the inner flange onto the spindle. Fit the wheel/disc
on the inner flange and screw the lock nut onto the spin-
dle. (Fig. 7)
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. (Fig. 8)
To remove the wheel, follow the installation procedure in
reverse.
Installing or removing diamond wheel
(optional accessory) (Fig. 9)
CAUTION:
• Make sure that the arrow on the tool should point in the
same direction as the arrow on the diamond wheel.
Mount the inner flange onto the spindle. Fit the diamond
wheel on over the inner flange and screw the lock nut onto
the spindle. Notice that flat side of the lock nut should face
the diamond wheel in case the diamond wheel is used.
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 grind-
ing.
• NEVER bang or hit grinding disc or wheel onto work.
• Avoid bouncing and snagging the wheel, especially
when working corners, sharp edges etc. This can
cause loss of control and kickback.
• NEVER use tool with wood cutting blades and other
sawblades. Such blades when used on a grinder fre-
quently kick and cause loss of control leading to per-
sonal injury.
CAUTION:
• Make the depth of a single cut up to 5 mm. Adjust pres-
sure on the tool so that the tool does not slow down
during the operation.
• After operation, always switch off the tool and wait until
the wheel has come to a complete stop before putting
the tool down.
