Air Tool Hook Up
Before _e tool is connected to _e air
supply, clear 1be air hose of accumulated
dustand moisture by running air freely
• rough _e air hose for _lOseconds.
Air Hoses for your Air Tools
Figure 1 Illuslzates a recommended air
hose hook up.
A 3/Sinch ID air hose is required up to a
leng_ of 25feet A 3/Sinch ID hose
Ionger_an 25feetwill cause a pressure
drop and may impede performance. If
more leng_ is required, a 1/zinch ID air
hose is recommended. Be sure all hoses
and fitlJngs are _e correctsize and
correctly secured before using _e tool.
Never carry a tool by _e hose or pull _e
hose to move _e tool or a compressor.
Keep hoses away from heal oil and sharp
edges. Replace any hose _atis 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 _an your system will
encounter.
Never use PVC pipes for
compressed air piping systems as
explosion and serious injury may
result
The connection from _e compressor
to _e inilJal take_ffhard pipe must
be a flexible hose in order to isolate
movement of _e compressor.
Route _e inilJal take4Dffline (pipe)
as slzaight up _e shop wall and as
high as possible. This will help
minimize water leaving _e
compressor and lzaveling _rough
system
Slope _e main lines down at least
3/4 inch per lOfeet of pipe away
from air compressor; _is will draw
• e condensate wi_ _e flowofair
and away from _e compressor.
Place _e firstdrop as far from _e
compressor as _e size of your shop
will allow (£Ofeetis optimal, al_ough
unrealislJc fora small shop). The
furtlqer _e drop, _e more _at
condensation can occur, and _e
drier _e airwill be when itreaches
• e water separator.
This tools power regulator valve may be
adjusted by rotalng _e switch, unlJl
desired oulputis achieved. The center is
neural, to _e leftis reverse and to _e
rightis forward. The fur_eryou go in
each direction _e more torque _atwill
be achieved.
The power can be regulated only in _e
forward direction. The tool will only
operate in full power in _e reverse
direclJon. Once a boltor fastener is
seated, impaclJng for longer 1ban 10
seconds could damage 1be impacting
mechanism. Ifittakes Ionger_an 10
seconds to remove _e desired fastener,
itis recommended _atyou use of a
larger impactwrench.
In order to reduce _e amountof
water and contaminants _atget into
• e water separator, install _e take-
offline on _e top of_e main air
supply line for each air drop.
Figure 2
A drain line should be placed at_e
end of_e main line for condensate
drainage.
Drain valves should be placed at_e
end of branch lines and _e drain
line, and drained daily.
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. If it takes longer than five
seconds to tighten or loosen your bolt
or fastener, we recommend the use of a
larger size impact wrench.
