Operation
The angle grinder must be
properly lubricated before operation. See
“Lubrication” section.
Figure 1
1.
Install side handle (Figure 1) into threaded
hole on grinder.
2.
Press spindle lock and rotate spindle until
lock engages. Continue pressing spindle
lock while loosening screw counterclockwise
from spindle with provided hex wrench.
Remove screw and outer flange.
3.
Install grinding wheel. Reinstall outer flange
and screw, and tighten screw while pressing
spindle lock.
Make sure spindle screw
is tight before operating grinder.
4.
Remove protective cap from air inlet (Figure
2). If an in-line oiler is not being used, add 4
or 5 drops of air tool oil (not included) into the
air inlet.
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
safety lever out of the way while pressing
throttle lever. Pressure against throttle lever
determines speed of rotation.
7.
The regulator screw beneath the housing
can be turned to adjust air intake, if
necessary.
8.
Position grinding wheel against workpiece
with a steady pressure. Wheel rotation is
clockwise when viewed from above the tool.
(A directional arrow is inscribed at front of
grinder.)
9.
Release throttle lever to stop grinder.
10. To reposition disc guard, loosen guard screw
(Figure 1) and rotate guard to desired
position, then retighten screw.
Do not remove guard
from grinder. Make sure guard screw is
tight before operating.
Maintenance
Lubrication
The grinder should be lubricated
daily
(or before
each use) with air tool oil through the air inlet.
During continual operation, it should be re-oiled
every 1 to 2 hours. This can be done with an in-
line oiler, or manually. If done manually, proceed
as follows:
1.
Disconnect air hose from tool.
2.
Place 4 or 5 drops of air tool oil into air inlet.
