*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.
We, Snap-on Tools Company, cannot be held liable 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 FAR2500/FAR2505 Air Ratchet is a
rugged, variable speed, reversible air ratchet that is
ideal for many confined automotive and industrial
applications.
It is designed and built to make fast work of light duty
fastener turning jobs that do not require more than 35
ft. lb. (47 N•m) torque.
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.
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
2
K – Low Spot, Water Trap
2
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.
Air Compressor
The air compressor should have sufficient capacity to
deliver 3.8 cfm (27 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 ratchet. Water, dirt and
scale act as abrasives which could damage the air
ratchet. A filter unit should be installed between the
compressor and the air regulator and air lubricator.
