Air Compressor
The air compressor should have sufficient capacity to
deliver CFM at 90 psig (6.2 bar, 620 kPa) at each outlet
while the tool is running. The receiver tank should have
sufficient capacity to provide surge balance for each air
tool.
Filter
The Snap-on AHR424 Filter, or equivalent, should be
used to assure clean air for the tool. Water, dirt and scale
act as abrasives which could damage the air tool. 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 air impact wrench. The Snap-on
AHR426 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 blows and
speed beyond the rated capacity—creating potential
hazards and possible damage to the air impact wrench.
Check the air pressure at the regulator while using the
impact wrench 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 air impact wrench
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 wrench 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 ratchet each
day before using, and again at the end of each
work day.
Air Strainer
An air strainer is built into the removable air inlet bushing
located at the rear of the ratchet. 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 reinstalled air inlet bushing to
90-150 lbs. ft. (11-17 N•m).

Power/Speed Regulator
The ratchet'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 speed from approximately 260
rpm down, depending on the air pressure in the line.
Turning the screw clockwise increases the power and
speed; counterclockwise decreases them.
Installing Sockets
The PTR2500 uses 1/4" square drive sockets. The
PTR2505 uses 3/8" square drive sockets. Be sure that
only power or impact sockets are used.
Maintenance
Service
Service of a tool requires extreme care and knowledge.
Service should be performed only by a qualified service
technician.
• Always check tool for damaged parts before use.
• Replace or repair damaged parts before use. Check
alignment of moving parts. Binding of moving parts or
broken parts may alter operation.
Have damaged parts properly repaired or replaced by an
Authorized Service Center.
• Do not use tool if switch does not turn it on and off.
• Maintain tools. Keep tools dry, clean and free of oil and
grease for better and safer performance.
• For the location of the nearest Snap-on repair center, call
Snap-on customer service at 1-877-762-7664.
