Air Inlet
AIR SUPPLY
Tools operate on a wide range of air pressures. It is
recommended that air pressure measures 90 psig at
the tool with the trigger fully depressed and no load
applied to the tool. Higher pressure (over 90 psig; 6.2
bar) raises performance beyond the rated capacity of
the tool, which will shorten tool life and could cause
injury.
Always use clean, dry air. Dust, corrosive fumes and/
or water in the air line will cause damage to the tool.
Drain the water from air lines and compressor prior to
running tool. Clean the air inlet filter screen weekly.
The recommended hookup procedure can be viewed
in FIG. 1.
The air inlet used for connecting air supply has
standard 1/4" NPT. Line pressure should be increased
to compensate for unusually long air hoses (over 25
feet). Minimum hose diameter should be 3/8" I.D. and
fittings should have the same inside dimensions and
be tightly secured.
Ensure an accessible emergency shut off
valve has been installed in the air supply
line and make others aware of its location.
TROUBLESHOOTING
Other factors outside the tool may cause loss of
power or erratic action. Reduced compressor output,
excessive drain on the air line, moisture or restrictions
in air pipes or the use of hose connections of improper
size or poor conditions may reduce air supply. Grit
or gum deposits in the tool may cut power and
may be corrected by cleaning the air strainer and
flushing out the tool with gum solvent oil or an
equal mixture of SAE #10 and kerosene. If outside
conditions are in order, disconnect tool from hose and
take tool to your nearest authorized service center.
LUBRICATION AND MAINTENANCE
Lubricate the air motor daily with high quality air
tool oil. If no air line oiler is used, run 1/2 oz. of
oil through the tool. The oil can be squirted into
the tool air inlet or into the hose at the nearest
connection to the air supply, then run the tool.
A rust inhibitive oil is acceptable for air tools.
WARNING: After an air tool has been lubricated,
oil will discharge through the exhaust port
during the first few seconds of operation. The
exhaust port must be covered with a towel before
applying air pressure to prevent serious injury.
OPERATION
Always turn off the air supply, drain hose of air
pressure and detach tool from air supply before
installing, removing or adjusting any part or accessory
on this tool, or before performing any maintenance on
this tool.
Bonded abrasive mounted point grinding wheels,
rotary files and carbide burrs can be mounted
providing their speed rating exceeds the speed
of the Die Grinder. The shank size of the mounted
accessory must match the collet size fitted in the Die
Grinder. Insert the shank of the mounted point as far
as possible into the collet and tighten the nut using the
supplied wrenches. Minimum shank gripping length
must be 10mm.
Correct bonded abrasive mounted point grinding
wheels, rotary files and carbide burrs are necessary
to prevent injury from broken accessories. Do not use
chipped or cracked bonded abrasive mounted point
grinding wheels, rotary files and carbide burrs. Tighten
the bonded abrasive mounted point grinding wheels,
rotary files and carbide burrs on the collet to prevent
spin off when the Die Grinder is turned off.
After mounting a new point, start the Die Grinder
under bench and run for a few seconds. If the Die
Grinder starts to vibrate when first fitting a mounted
point or during operation, immediately remove from
service. If Die Grinder is dropped, replace bonded
abrasive mounted point grinding wheel, rotary file or
carbide burr.
When using the Die Grinder, be careful not to exert
excessive force which could be hazardous and cause
mounted spindle to bend or break.
NOTE: During operation, safety goggles should
always be worn to guard against flying debris
(users and bystanders).
WARNING: Never mount a grinding wheel, cut-off
wheel, router cutter or drill bit on a Die Grinder.
Never use an arbor, mandrel or any other adapter
to convert the Die Grinder for any other application.
