Applications
Snap-on AT380 Impact Wrench is 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
The pneumatic impact wrench operates best on clean,
moisture-free, well-lubricated air at a constant
pressure of 90 psig (6.2 bar, 620 kPa) maximum.

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 5/16" inside diameter or one
that is too long because pressure drop under
maximum flow conditions could reduce performance.
The Snap-on AHC22 Quick Coupler and the AHC22M
and AHC22F adaptors are recommended for use with
this air tool. Also recommended for use are the
AHCC98 Universal Coupler and the AHCCP97 High
Flow Fitting.
Air Compressor
m/s²
The air compressor should have sufficient capacity
to deliver 3.5 cfm (24 SCFM) 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 air impact wrench.
Water, dirt and scale act as abrasives which could
damage the air 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 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.
