using grinder
always test the grinder on a scrap piece
of material similar to the workpiece. trial
and error is the best way to determine the
ideal setup.
air pressure
hazard!
never exceed max
psi rating for tool.
to use the grinder:
1. Make sure the workpiece is securely
held in a vise or a similar device that
will ensure the workpiece does not
unexpectedly move during operation.
daily maintenance
the angle grinder Must have 4-5 drops
of pneumic tooodcly drpped into
the nepot beore anafer each
use. in addition, add oil after 3–4 hours
of continuous use or install an in-line
filter, lubricator, and regulator, as shown
in figure 3.
2. attach the grinder to an air supply set
at 90 psi.
3. hold the grinder securely, turn the
grinder ON by depressing the trigger,
then ease the grinding wheel against
the workpiece with a light, but steady,
pressure.
these procedures should be done after
each use:
•
Wipe the grinding housing with a dry
cloth, or blow off the dust and debris
with compressed air.
note: Vary the grinding wheel speed
by the pressure used on the trigger.
4. to turn the grinder OFF, release the
trigger.
•
Check for damage to grinding wheels,
hoses, housing, or other accessories.
note: To avoid accidental start up, dis-
connect the grinder from the air supply
when it is not in use, and replace the
protective cap into the air inlet port.
