PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specifi ed 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 suffi cient 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 length ℓ is less than 15 mm.
If ℓ is longer, abnormal vibration will occur, and the
machine is not only negatively aff ected, but there is a
possibility of a serious accident.
Make the ℓ as 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
ø 6
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.
