*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.

Applications
The Snap-on PTR2500 & PTR2505 Ratchet 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
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: Air Supply
A – Receiver Tank, Minimum 40 Gallon
(151.5 liters)
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 3/8" ID or one that is too long
because pressure drop under maximum flow conditions
could reduce performance.
√ Accessories are available for air tight connections.
The quick coupler, Snap-on part number AHC21,
and adaptor, Snap-on part number AHC21M, are
recommended for use with this air ratchet.
