Model H8218 Mini 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. Turn the grinder ON by depressing the
trigger.
5. Securely holding the grinder, ease the
working end of the bit against the
workpiece with a light, but steady, pres-
sure.
6. To turn the grinder OFF, release the
trigger.
7. To avoid accidental starting, discon-
nect the grinder from the air supply
when it is not in use.
Daily Maintenance
The die grinder MUST have 2-6 drops of oil
directly dropped into the air fitting before
each use. In addition, we recommend using
an in-line filter, lubricator, and regulator, as
shown in Figure 3.
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.
