OPERATING AND SERVICE INSTRUCTIONS
READ SAFETY RECOMMENDATIONS BEFORE CON-
NECTING TOOL.
The 15G Series Grinders are designed to operate on 90
psig (6.2 bar) maximum air pressure, using a 3/8" hose up
to 8' in length. If additional length is required, the next
larger hose size may be connected to the 8' whip hose.
LUBRICATION
An automatic in-line filter- regulator- lubricator is recom-
mended as it increases tool life and keeps the tool in
sustained operation. The in-line lubricator should be regu-
larly checked and filled with a good grade of 10W machine
oil. Proper adjustment of the in-line lubricator is performed
by placing a sheet of paper next to the exhaust ports and
holding the throttle open approximately 30 seconds. The
lubricator is properly set when a light stain of oil collects on
the paper. Excessive amounts of oil should be avoided.
STORAGE
In the event that it becomes necessary to store the tool for
an extended period of time (overnight, weekend, etc.), it
should receive a generous amount of lubrication at that
time and again when returned to service. The tool should
be stored in a clean and dry environment.
DISASSEMBLY
To disassemble the 15G model, remove the retainer ring,
driving flange, exhaust deflector retainer ring, exhaust
deflector, and unscrew the front bearing retainer, No.
865697, (left hand threads). The motor assembly may
now be slipped out the front of the backhead.
REASSEMBLY
If the tool has been completely disassembled, assemble
the various subassemblies per their instructions. After
assembly of the complete tool, the R.P.M. must be checked.
To change the R.P.M. settting on the 15G, the governor
will have to be removed (left hand threads) and the
governor adjusting screw rotated clockwise to decrease
the speed, and counter-clockwise to increase the speed.
Check speed of tool before mounting wheel. Mount wheel
guard before mounting wheel.
