Air Tool Hook Up
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 Tools
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 ½ inch ID air
hose is recommended, Be sure all hoses
and fittings are the correct size and
correctly secured before using the tool,
Never carry a tool by the hose or pull the
hose to move the tool or a compressor.
Keep hoses away from heat, oil and sharp
edges, Replace any hose that is damaged,
weak or worn.
Small (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 wall 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,
This tool features a power regulator valve
(fig. 2), Rotate regulator until desired
output is achieved, The settings on the
regulator are only for reference and do not
denote a specific power output, Turn
regulator to a position with the sinlge
circle being the least amount of power and
the three circles being the most amount of
power,
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,

Forward/Reverse Lever
Once a bolt or fastener is seated,
impacting for longer than five (5)
seconds will cause excessive wear and
possible damage to the impacting
mechanism, ff it takes longer than five
seconds to tighten or loosen your bolt
or fastener, we recommend the use of a
larger size impact wrench,
