Grinders
Features and Benefits
Stanley’s GR30 Grinder embodies
the latest product improvements in
this tool. The vertical grinder now has
the Stanley Dual Spool Selector which
allows the tool to be set for either
open-center or closed-center systems.
All the screw fasteners are
stainless steel. The trigger spool is
stainless steel. A trigger lock prevents
accidental starting of the
grinder.
The integral Stanley HyrevzTM gear
motor is manufactured to exacting
standards to deliver maximum efficiency.
The over-sized motor run-down
valve allows the motor to freely run
down in speed when the grinder is
turned off ensuring that a properly
installed wheel will not spin off the
spindle.

The built-in reverse-check valve in
the handle prevents operating the
grinder when reverse-plumbed to the
hydraulic system. Preventing reverse
operation ensures a long operating life
for the hydraulic seals.
The thick, tough layer of foamedplastisol
covering the handle transmits
very little heat. The foamed
plastisol gives a more comfortable grip
to the tool.
The cast-in lifting eye is always
available, unlike screwed-in lifting
rings which may come loose and fall
off.
The Stanley dual-spool selector is
accessable under a seal plug at the
rear of the tool. Setting the tool for
open- or closed-center operation is as
simple as opening or closing a valve.
The selector is not susceptible to
moving under the vibration of use and
is completely protected from accidental
or unintentional access. The seal
plug also protects the end of the
trigger spool and dual-spool selector
from water and dirt.
There are two positions available
for the assist handle to be conveniently
placed by the operator. Either
position is at a most comfortable
handling position from the valve
handle.
The wheel guard is adjustable. By
loosening the clamp screw which has
an integral toggle handle, the guard
may be rotated to any convenient
position.
The grinders can be used with standard
grinding wheels and brushes that
are rated for at least 6500 rpm and
have a hub with 5/8-11UNC straight
thread.
