Filter
The Snap-on AHR424 Filter, or equivalent, should be
used to assure clean air for the die grinder. Water, dirt
and scale act as abrasives which could damage the die
grinder. A filter unit should be installed between the
compressor and the air regulator and air lubricator.
Air Regulator
Regulated air pressure is necessary for proper
performance of the die grinder. The
Regulator, or equivalent, will adjust and maintain the
recommended air pressure of 90 psig (6.2 bar,
620 kPa). Pressure less than this reduces efficiency,
while pressure greater than this increases speed
beyond the rated capacity—creating potential
hazards and possible damage to the die grinder.
Check the air pressure at the air inlet while using the
die grinder in a normal manner.
Air Line Lubricator
√ Do not use a heavy grade of oil because stalling and
low performance will result.
The preferred method of lubricating the die grinder
motor is to use an air line lubricator such as the
Snap-on AHR428 Lubricator. It should be filled with
Snap-on IM6 Air Motor Oil or a good grade of
SAE 10W oil.
If an air line lubricator is not used, lubricate the air
motor by injecting approximately 1/8 oz (3.75 ml) of
IM6 Air Motor Oil into the air inlet of the die grinder
each day before using it. IM6 Oil is specially
formulated for air tools and no flushing solvent is
needed.
Flushing
If the unit seems sluggish apply 3 or 4 squirts of
IM6 Air Motor Oil into the air inlet of the die grinder
each day before using, and again at the end of each
work day.
Lubrication
Lubricate the gears of the PTGR110 through the
grease fitting on the angle head with Snap-on
YA190DIS grease after every 8 hours of operation.
Air Strainer
An air strainer is built into the removable air inlet
bushing located at the rear of the die grinder. To
clean, remove the bushing and use an air hose to
blow dirt and other particles from the screen and
bushing. Torque the air inlet bushing to 90-150 lb.
ins. (13 N•m).
Power/Speed Regulator
The die grinder operates in the clockwise
direction when viewed from the operator's
position .
The die grinder's power and speed can be adjusted by
turning the regulator screw located on the side of the
body, opposite that of the throttle lever. The
regulator's ten settings provide a free speed range of
approximately 10,000 to 25,000 rpm. Turning the
