/4" Angle Die Grinder -5-
Using the Grinder
Always test the tooling bit on a scrap piece
of material similar to the workpiece. Trial
and error is the best way to determine the
ideal setup.
To use the grinder:
1. Attach the
1
/4" NPT male quick connect
fitting to the air inlet plug.
2. Attach the grinder to an air supply set
at 90 PSI.
3. Hold the grinder securely.
4. Using the trigger to control RPM, ease
the working end of the bit against the
workpiece with a light, but steady, pres-
sure.
Daily Maintenance
Drop 2-6 drops of air tool oil directly into
the air fitting before using the die grinder.
In addition, drip 2-6 drops of oil directly
into the ball oiler located in the angle
housing, as shown in Figure 3.

For improved lubrication to extend the life
span of your die grinder, we recommend
using an in-line filter, lubricator, and
regulator, as shown in Figure 4.
These procedures should be done after
each use:
• Wipe the motor housing and tool bits
with a dry cloth, or blow off the dust and
debris with compressed air.
• Check for damage to tooling, hoses,
housing or other accessories.
• Relubricate with 2-6 drops of oil before
storage.

To avoid accidental starting,
