Be sure to check the nameplate on product as it is subject to change by areas.
* This varies depending on the area.
Electronic Control
The grinder has an electronic speed control which
provides:
○ full speed at all times in the range up to rated load.
○ soft-start.
○ variable speed
NOTE
The grinder is equipped with a rotational speed control
circuit. The rotational speed may fl uctuate slightly due to
the conditions of use and working voltage.
NOTE
Due to HITACHI's continuing program of research and
development, the specifi cations herein are subject to

Installing a wheel (Fig. 3)
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 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.
