Before the tool is connected to the air
supply, clear the air hose of accumulated
dust and moisture by running air freely
through the air hose for 5-10 seconds.
Air Hoses for your Air Toois
Figure 1 Illustrates a recommended air
hose hook up.
A 3/8 inch ID air hose is required up to a
length of 25 feet. A 3/8 inch ID hose
longer than 25 feet will cause a pressure
drop and may impede performance. If
more length is required, a /2 inch ID air
hose is recommended. Be sure ail hoses
and fittings are the correct size and
correctly secured before using the tool.
ENG-6
Keep hoses away from heat, oil and sharp
edges. Replace any hose that is damaged,
weak or worn.
Smaii (home) shop hard piping:
A piping diagram for a typical home shop
is shown. Some helpful tips are:
• Always use hoses and pipes rated for
higher pressure than your system will
encounter.
• Never use PVC pipes for
compressed air piping systems as
explosion and serious injury may
result.
• The connection from the compressor
to the initial take-off hard pipe must
be a flexible hose in order to isolate
movement of the compressor.
Route the initial take-off line (pipe) as
straight up the shop wail and as high
as possible. This will help minimize
water leaving the compressor and
traveling through system.
Slope the main lines down at least
3/4 inch per 10 feet of pipe away
from air compressor; this will draw
the condensate with the flow of air
and away from the compressor.
Place the first drop as far from the
compressor as the size of your shop
will allow (50 feet is optimal, although
unrealistic for a small shop). The
further the drop, the more that
condensation can occur, and the
drier the air will be when it reaches
the water separator.
In order to reduce the amount of
water and contaminants that get into
the water separator, install the take­
off line on the top of the main air
supply line for each air drop.
A Drain line should be placed at the
end of the main line for condensate
drainage.
Drain valves should be placed at the
end of branch lines and the drain
line, and drained daily.
Operation
The Craftsman 3/8" Drive Ratchet Wrench
is designed to operate on 90 PSIG. Lower
pressure (below 90 PSI) will reduce
performance of the tool while higher air
pressure (over 90 PSI) raises the
performance of the tool beyond its rated
capacity and could cause serious
damage to tool and user.
Speed Adjustment
The ratchet should never be used to
set the torque. Use a torque wrench to
set the torque.
ik¥¥ARNIiyG
When tightening,do not torque down
the nuts or boits with the ratchet as
typicaiiy done with a hand wrench. This
can damage the tooi by breaking parts
in the ratchet mechanism.____________
