Grinder Operation - Metabo HPT G 3612DA 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 G3612DA and G3612DB 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 fi rmly by its housing and side handle
(Fig. 1).
The grinder produces a counterforce which must be
controlled by fi rmly holding onto the grinder.
2. Turn the grinder "on".
<G3612DA> (Fig. 11)
While holding the grinder fi rmly, use one fi nger to slide

3. Use light grinding pressure.
There is no need to press hard when grinding. Usually
the grinder's own weight is suffi cient to allow the
required light contact with the surface to be ground.
Do not apply the grinding wheel strongly to the grinding
surface. The grinder makes use of electronic circuit,
so during application of load rotates at high speed,
so ample grinding eff ect can be obtained by applying
light pressure. If a strong grinding pressure or other
abnormal load is applied, the overload protection
circuit will operate and make the grinder stop rotating,
so please stop applying load immediately. Following
this, switching the power OFF and then ON again, will
cause the rotation to increase to the regular speed.
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. 13.
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. 13), the wheel edge may cut into the workpiece.
In this case, grind in direction B (Fig. 13).
Once the wheel edge is worn, the workpiece can be
ground in both directions.
