If you continue to use the tool and exhaust the electric
current, the battery may be damaged and its life will
become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
use, its internal chemical substance will deteriorate,
and the battery life will be shortened. Leave the
battery and recharge it after it has cooled for a while.
CAUTION
● When the battery charger has been continuosly
used, the battery charger will be heated, thus
constituting the cause of the failures. Once the
charging has been completed, give 15 minutes
rest until the next charging.
● If the battery is rechraged when it is warm due
to battery use or exposure to sunlight, the pilot
lamp may light in green.
The battery will not be recharged. In such a case,
let the battery cool before charging.
● When the pilot lamp fl ikers rapidly in red (at
0.2–second intervals), check for and take out
any foreign objects in the charger's battery
installation hole. If there are no foreign objects,
it is probable that the battery or charger is
malfunctioning. Take it to your authorized
Service Center.
PRIOR TO OPERATION
1. Power switch
Ensure that the switch is in the OFF position.
2. Check your work environment
Ensure the following before operation:
○ No fl ammable gas, liquid, or object at worksite.
○ When grinding thin steel sheet it may cause a high
booming noise.
To avoid such noise, place a rubber mat under the
workpiece.
○ Clear the area of children or unauthorized
personnel.
3. Mounting the wheel guard
Be sure to mount the wheel guard at an angle that will
protect the operator's body from injury by a broken
wheel piece.
[Installing Wheel Guard]
○ Slightly loosen the screw on the wheel guard.
○ Install the wheel guard to the packing gland, turn
it to the angle suitable for operation, and make
adjustment.
○ After the adjustment, ensure that the screw is
securely tightened on the wheel guard in order to
fi x it completely.

WARNING
If the wheel guard is not attached properly, a
broken wheel may result in and cause death or
serious injury.
4. Thoroughly check that the depressed center wheel
is free of cracks, splits and other abnomalities before
mounting. Make sure it is fi rmly clamped and has
been properly mounted. Refer to page 16 of this
manual for Depressed Center Wheel Assembly and
Disassembly
5. Test the grinder before using.
Before actually beginning the grinding work, test the
grinder by fi rst clearing the area of all other personnel.
Make sure the wheel guard is in place and that you
are wearing eye protection. Turn the grinder "on", and
make sure the grinder runs smoothly and shows no
abnormalities.
Duration of the trial run is as follows:
When depressed center wheel
is replaced .............................. 3 minutes or more
When starting daily work .......... 1 minute or more
6. Use only properly rated depressed center wheels.
Use only depressed center wheels rated at 13,300
RPM or more.
Using a depressed center wheel rated less can lead
to wheel disintegration during operation and cause
serious bodily injury.
7. Check the push button.
Make sure that the push button is disengaged by
pushing push button two or three times before turning
on the grinder. (Fig. 8)
