Parts Breakdown & Operating Manual

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.
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
