English

APPLICATIONS

○ Finishing of dies for press working, die casting and
moulding.
○ Finishing of thread cutting dies, tools and other small
parts.
○ Internal grinding of tools and machine parts.
WARNING
To avoid the risk of serious injury, NEVER use this
grinder with abrasive wheels, cut-off wheels and/
or saw blades.
Use only with mandrel mounted abrasive stones.

PRIOR TO OPERATION

1. Power source
Ensure that the power source to be utilized conforms
to the power source requirements specifi ed on the
product nameplate.
2. Power switch
Ensure that the switch is in the OFF position. If the
plug is connected to a receptacle while the switch is
in the ON position, the power tool will start operating
immediately and can cause serious injury.
3. Extension cord
When the work area is far away 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.
WARNING
Damaged cord must be replaced or
repaired.

4. Check the receptacle
If the receptacle only loosely accepts the plug, the
receptacle must be repaired. Contact a licensed
electrician to make appropriate repairs.
If such a faulty receptacle is used, it may cause
overheating, resulting in a serious hazard.
5. Check the work site and surrounding area
Be sure that the work area has been thoroughly
checked and prepared to avoid any unsafe conditions.
Review the SAFETY section of this manual.
6. Installing a wheel
WARNING
USING A WRONG SIZED WHEEL OR A WRONG
RATED ROTATION SPEED WHEEL CAN CAUSE
WHEEL BREAKAGE AND RESULTING SERIOUS
INJURY.
In order to avoid this hazard, refer to the following
rated rotation speed wheel and the following
illustration to determine the proper dimensions(s)
of your wheel. Some guidelines:
(a) Use only wheels rated at 30,800/min for GP3V and
8,820/min for GP5V or more. Using wheel rated less
can lead to wheel disintegration during operation and
cause serious bodily injury.
(b) Dimension ℓ should always be less than 1/2" (13 mm).
Longer lengths can result in excess vibration, wheel
breakage, and the chance for serious injury.
(c) When dimension d is 1/4" (6.35 mm), the diameter of
the wheel (dimension D) should be less than 1" (25 mm)
for GP3V and less than 2" (50 mm for GP5V). NEVER
use a longer diameter wheel.
(d) When dimension d is 1/8" (3.175 mm), the diameter of
the wheel (dimension D) should be less than 3/8" (10
mm) for GP3V and less than 3/4" (20 mm for GP5V).
(e) Dimension L varies according to the dimension D.
Dimension L can be longer as dimension D increase.
