PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specified on the product
nameplate.
NOTE:
When connected to the power supply, the built-in
electronic control circuit shifts to standby status and
the grinder becomes slightly warm, but this is not
a malfunction.
CAUTION
Do not operate from a direct current power source,
engine generator, booster or any other type of
transformer. Doing so may not only cause damage
to the grinder, but may lead to accidents.
2. Power switch
Ensure that the power switch is in the OFF position.
If the plug is connected to a receptacle while the
power switch is in the ON position, the power tool
will start operating immediately, which could cause
a serious accident.
3. Extension cord
When the work area is removed from the power
source, use an extension cord of sufficient thickness
and rated capacity. The extension cord should be
kept as short as practicable.
4. RCD
The use of a residual current device with a rated
residual current of 30mA or less at all times is
recommended.
5. Installing a wheel
Install the wheel so that lengthris less than 15 mm.
If r is longer, abnormal vibration will occur, and
the machine is not only negatively affected, but
there is a possibility of a serious accident.
Make theras small as possible.
When d = 6 mm, 6.35 mm (1/4"), 8 mm, D of the
wheel should be less than the Max. wheel diam.
of each models (GP3V: 25 mm, GP5V: 50 mm). If
a wheel with D more than the Max. wheel diam.
of each models (GP3V: 25 mm, GP5V: 50 mm) is
used, the circumference speed exceeds the safety
limit and the wheel will break. Never use such a
wheel.
Distance L varies for D. Determine L referring to
the table below.
When d = 3 mm, 3.175 mm (1/8"), D should be less
than 10 mm. Determine L referring to the table
below.
Wheels can be simply attached and detached by
using the two wrenches. (Fig. 2).
NOTE:
Do not tighten the collet chuck by inserting a shaft
thinner than the regular shaft diameter (6 mm) in
the chuck or in an empty condition. This practice
will damage the collet chuck.
When installing a wheel with shaft, tighten the
collet chuck after applying a small quantity of spindle
oil (or sewing machine oil) to the tapered portion
indicated in Fig. 1.
