or wrap chains around the draw bar and hook
them to themselves to keep chains off t he
ground which might accelerate rusting.
8. If provided, lower front screw jack drawbar
stabilizer and/or any front and rear stabilizer
legs. Make sure the surface t hey contact has
sufficient load bearing capability to support the
weight of the compressor.
WARNING
!
Retract the front stabilizer leg only after attaching
the compressor to the tow vehicle. R emove the
pin on top of the drawbar and place the stabilizer
leg in its full---up position. R einsert the pin and
make sure it is secured in place prior to towing.
If a retractable caster wheel is provided, pull the
lock pin and fold and raise the caster wheel, mak-
ing sure the pin is re---engaged to secure the cast-
er wheel in the full---up and locked position with
the wheel horizontal pr ior to towing.
WARNING
!
This equipment may be tougue heavy. DO NOT
attempt to raise or lower the drawbar by hand if
the weight is more than you can safely handle.
9. If the compressor is provided w ith a swivel
caster w h eel, pull pin and lower caster wheel,
then make sure pin is re---engaged to secure
caster wheel in the full---down and locked posi-
tion.
10. Disconnect coupling device, keeping hands
and fingers clear of all pinch points. If the com-
pressor is provided with a drawbar, DO NOT at-
tempt to lift the draw bar or if hinged, to raise it to
the upright position, by hand, if the weight is
more than you can safely handle. Use a lifting
device such as a jack or chain fall if you cannot
lift or raise the drawbar without avoiding injury to
yourself or others.
11. When possible, stow hinged drawbar in the
vertical upright position. Make certain it is se-
curely latched in the vertical upright posit ion.
Keep feet clear of drawbar at all times to avoid
crushing accidents in case it should slip from
your hands or otherwise fall to the ground.
12. Move the towing vehicle well clear of the
parked compressor and erect hazard indica-
tors, barricades and/or flares (if at night) if com -
pressor is park ed on or adjacent to public roads.
Park so as not to interfere with traffic.
(I) While not towed in the usual sense of the word,
many of these instructions are directly applica-
ble to skid---mounted portable air compressors
as well.
1.3 PRESSURE RELEASE
A. Open the pressure relief valve at least weekly to
make sure it is not blocked, closed, obstructed or
otherwise disabled.
B. Install an appropriate flow ---limiting valve be-
tween the compressor service air outlet and the
shutoff (throttle) valve, when an air hose exceed-
ing 1/2” (13mm) inside diameter is to be connected
to shut---off (throttle) valve, to reduce pressure in
case of hose failure, per OSHA Standard 20 CFR
1926.302 (b) (7) or any applicable Federal, State
and Local codes, standards and regulations.
C. Whenthehoseistobeusedtosupplyamani-
fold, install an additional appropriate flow---limiting
valve between the manifold and each air hose ex-
ceeding 1/2” (13mm) inside diameter that is to be
connected to the manifold to reduce pressure in
case of hose failure.
D. Provide an appropriate flow---limiting valve for
each additional 75 feet (23 meters) of hose in runs
of air hose exceeding 1/2” (13mm) inside diameter
to reduce pressure in case of hose failure.
E. Flow---limiting valves are listed by pipe size and
rated CFM. Select appropriate valve accordingly.
F. D O N O T use tools that are rated below the maxi-
mum rating of this compressor. Select tools, air
hoses, pipes, valves, filters and other fittings ac-
cordingly. DO NOT exceed manufacturer’s rated
safe operating pressures for these items.
G. Secure all hose connections by wire, chain or
other suitable retaining device to prevent tools or
hose ends from being accidentally disconnected
and expelled.
H. Open fluid filler cap only when compressor is
not running and is not pressurized. Shut down
the compressor and bleed the sump (receiver) to
zero internal pressure before removing the cap.
I. Vent all internal pressure prior to opening any
line, fitting, hose, valve, drain plug, connection or
other component, such as filters and line oilers,
and before attempting to refill optional air line anti ---
icer systems with a ntifreeze compound.
J. Keep personnel out of line with and away from
the discharge opening of hoses, tools or other
points of compressed air discharge.
K. DO NOT use air at pressures higher than 30
psig (2.1 bar) for cleaning purposes, and then only
with effective chip guarding a nd personal protec-
tive equipment per OSHA Standard 29 CFR
1910.242 (b) or any applicable Fe deral, State and
Local codes, standards and regulations.
L. DO NOT engage in horseplay with air hoses as
death or serious injury may result.
M. This equipment is supplied with an ASME de-
signed pressure vessel protected by an ASME
