4.
Disconnect battery charger from the receptacle.
CAUTION
Do not pull the plug out of the receptacle by pulling
on the cord.
Make sure to grasp the plug when removing from
receptacle to avoid damaging cord.
5.
Remove the battery from the battery charger.
Supporting the battery charger with hand, pull out the
battery from the battery charger.
How to make the batteries perform longer
(1) Recharge the batteries before they become
completely exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery. 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 flikers 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.

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.
[How to attach and adjust the wheel guard] (Fig. 5)
Set the wheel ass'y to the packing gland.
Tighten M5 screw to secure the wheel guard

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 firmly 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 first 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.
