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:

⅜ 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.

⅜ 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.
