Air Regulator
Regulated air pressure is necessary for proper
performance of the die grinder. The Snap-on AHR416
Regulator, or equivalent will adjust and maintain the
recommended air pressure of 90 psig (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 regulator while using the 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 AHR418 Lubricator. It should be filled with
Snap-on IM6 Air Motor Oil or a good grade of
SAE-10W oil.
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 PTGR410 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. Before reinstalling the air inlet bushing,
check the O-ring for damage. If it is damaged, replace
it with a new O-ring to prevent air leakage. Torque the
air inlet bushing to 20-25 ft. lb. (27-34 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. Turning the
screw clockwise increases the power and speed;
counterclockwise decreases them.
1/4" Collet
The die grinder's collet is intended for retaining
accessories with 1/4" shanks. To use the adaptor,
simply insert it into the collet.
Installing Grinding Accessories
The collet nut and spindle hold various 1/4" grinding
accessories in the die grinder. Accessories are
attached as follows:
ZPTGR410CE Rev B
EN EN
— Insert the shaft of the grinding accessory at
least 7/16" into the spindle.
— Using a 9/16" wrench to hold the spindle
stationary, tighten the collet snugly onto the
spindle, using a 3/4" wrench. Check that
accessory is tight in the spindle before use.
