*These declared values were obtained by
laboratory type testing with the stated standards
and are not adequate for use in risk assessments.
Values measured in individual work places may be
higher. Values and risk of harm experienced by an
individual user are unique and depend upon the
environment and manner in which the user works,
the work piece and the workstation design, as well
as upon the exposure time and the physical
condition of the user.
Snap-on disclaims liability for the consequences of
using the declared values, instead of values
reflecting the actual exposure determined in an
individual risk assessment in a work place situation
over which we have no control.
Application
Snap-on
PT1800 Impact Wrenches are ideal for a
wide variety of fastener turning jobs in both
automotive and industrial fields. When used with
Snap-on
impact sockets, they provide power and
speed for greater job efficiency and less operator
fatigue. Applications include assembly line
operations, removal of rusted-on nuts and bolts and
many other specialized uses.
Air Supply
Air tools operate best on clean, moisture-free,
well-lubricated air at a constant pressure of 90 psig
(6.2 bar, 620 kPa,) maximum.
Figure 1: Recommended Air Supply System
A – Receiver Tank, Minimum 40 Gallon
B – Compressor, Sufficient Capacity
C – Drain, Daily
D – Pipe and Fittings, Minimum 1/2"
E – Top Air Intake
F – Shut Off Valve, Easily Reached
G – Filter
H – Air Regulator, Set at Working Pressure
I – Lubricator
J – Air Tool Connection
K – Low Spot, Water Trap
L – Drain, Daily
Piping System
The piping system should be large enough to avoid
an excessive pressure drop under maximum flow
conditions. All pipe fittings and hose outlets should
be 1/2" and should be arranged so there are no low

spots that collect water which cannot be drained
daily. Do not use an air hose less than 1/2" ID or one

that is too long because pressure drop under
2
maximum flow conditions could reduce performance.

Air Compressor
The air compressor should have sufficient capacity to
deliver 8.6 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 impact driver. Water,
dirt and scale act as abrasives which could damage the
impact wrench. 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 impact wrench. The
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
speed beyond the rated capacity—creating potential
hazards and possible damage to the impact wrench.
Check the air pressure at the air inlet while using the
impact driver 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 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 impact wrench
each day before using it. IM6 Oil is specially formulated
for air tools and no flushing solvent is needed.
Oil Reservoir
The impact mechanism chamber is sealed at the
factory and should not require any additional oil.
Air Strainer
An air strainer is built into the removable air inlet
bushing located at the rear of the impact wrench. 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 35 lbs. ft. (47 N•m).
Forward/Reverse Controls
The directional control is located below the handle.
There is one (1) reverse setting and three (3) forward
settings. "1" is the lowest setting and "3" is the highest.
