Grinder Operation - Hitachi G 14DL Instructions De Sécurité Et Mode D'emploi

English

GRINDER OPERATION

CAUTION:
To extend the lifetime, the lithium-ion battery
equips with the protection function to stop the
output. Therefore, if the tool is overloaded, the
motor may stop. However, this is not the trouble
but the result of protection function. In this case,
release the switch of tool and eliminate the causes
of overloading.
NOTE:
To prevent injuries, this product has a function that
prevents unexpected motor rotation when the
battery is inserted. The motor will not run if the
battery is inserter while the switch is still ON. After
installing the battery, turn the switch off and then
back on again.
The G14DL and G18DL models are equipped with
a protection function that will shut down the tool
in the event of an overload.
Should the tool shut down due to an overload, turn
the power off and then turn it back on again.
An overload that stops tool operation and lasts
more than 10 seconds may not be released by
turning the power off and on. Should this happen,
remove the battery from the tool and reinstall it
before turning on the power switch.
1. Hold the grinder firmly by its housing and side
handle (Fig. 1).
The grinder produces a counterforce which must
be controlled by firmly holding onto the grinder.
2. Turn the grinder "on". (Fig. 6)
While holding the grinder firmly, use one finger to
slide the switch to the "on" position.
3. Use light grinding pressure.
There is no need to press hard when grinding.
Usually the grinder's own weight is sufficient to
allow the required light contact with the surface to
be ground.

WARNING:
Do not press the grinder forcibly against the
surface to be ground. Heavy pressure can result
in wheel breakage and serious injury. It can also
damage the surface being ground or damage the
grinder's motor.
4. Use proper grinding angle.
Grind only with the wheel's edge by lifting the
grinder 15° to 30°, as shown in Fig. 7.
CAUTION:
Do not use the entire surface of the depressed
center wheel. Use only the edge of the depressed
center wheel.
5. Move the grinder in the proper direction.
When using a new depressed center wheel in
direction A (Fig. 7), the wheel edge may cut into the
workpiece. In this case, grind in direction B (Fig. 7).
Once the wheel edge is worn, the workpiece can
be ground in both directions.

NOTE:
The wheel provided (resinoid wheel) is rated as
Class A grain and # 36 grain size. It is most suitable
for heavy grinding of steel and other types of
materials.
6. Adjust operation to desired finish.
For a fine finish, decrease pressure by lifting
slightly. Grind slowly and at the appropriate speed.
CAUTION:
The revolving depressed center wheel will create
air turbulence.
Do no lay the grinder down in areas of dust or dirt
until it has come to a complete stop.
