“Lubrication” section.
Figure 1
1.
Install side handle (Figure 1) into threaded
hole on side of grinder.
2.
Place open end wrench on flats of spindle
(Figure 2) and keep stationary. Place pin
wrench into holes of outer flange. Rotate
counterclockwise to loosen flange, and
remove it.
3.
Install grinding wheel. Reinstall and tighten
outer flange clockwise, using wrenches.

air inlet.
Figure 2
5.
Blow out air line to remove any dirt or
moisture, then connect air supply hose to
tool. Set air pressure to 90 psi.
IMPORTANT:
Connecting a quick-change
coupling directly to the tool is not
recommended, as vibration may cause the
connection to fail. Instead, add a leader hose
and install any quick-change couplings
farther down the line.
6.
Hold grinder with a light but secure grip. Slide
throttle lock out of the way while pressing
throttle lever. Pressure against throttle lever
determines speed of rotation.
7.
Position grinding wheel against workpiece
with a steady pressure. Wheel rotation is
clockwise when viewed from above the tool.
8.
Release throttle lever to stop grinder.
9.
The disc guard may be rotated by removing
three socket head screws, shown in Figure

Use at least 3 screws to secure the guard.
The guard must be
properly installed before operating this
tool.
