Prior To Operation - Hitachi G 14DL Manual De Instrucciones

NOTE:
Charging times may be longer depending on the
surrounding temperature and battery conditions.
Charge time lamp indications are only a guide, and
may vary depending on the surrounding
temperature and battery conditions.
Remove the battery from the charger when not in
use.
Regarding electric discharge in case of new
batteries, etc.
As the internal chemical substance of new batteries
and batteries that have not been used for an
extended period is not activated, the electric
discharge might be low when using them the first
and second time. This is a temporary
phenomenon, and normal time required for
recharging will be restored by recharging the
batteries 2 – 3 times.
How to make the batteries perform longer.
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.
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.

PRIOR TO OPERATION

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.
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)
