Pressure Release - Sullair 185 Operators Manual And Parts Lists

4. On four---wheel models, park compressor
with front wheels in straight ahead position.
5. Set parking brakes
breakaway switch cable and all other intercon-
necting electrical and/or brake connections, if
provided.
6. Block or chock both sides of all wheels.
7. If provided, unhook chains and remove them
from the points of chain attachment on the tow-
ing vehicle, then hook chains to bail on drawbar
or wrap chains around the drawbar and hook
them to themselves to keep chains off the
ground which might accelerate rusting.
8. Lower front screw jack and/or any front and
rear stabilizer legs. Make sure the surface they
contact has sufficient load bearing capability to
support the weight of the compressor.
WARNING
!
Retract the front screw jack only after attaching
the compressor to the tow vehicle. Raise the
screw jack to its full up position and pull the pin
connecting the jack to the drawbar. Rotate the
screw jack to its stowed position, parallel to the
drawbar, and reinsert the pin. Make sure the jack
is secured in place prior to towing.
If a caster wheel is provided on the screw jack it is
part of the screw jack and can not be removed.
Follow the same procedure for stowing away the
wheeled jack as you would for the standard screw
jack. Pull the pin connecting the jack to the draw-
bar and raise the screw jack to its full up position.
Rotate the screw jack to its stowed position, par-
allel to the drawbar, and reinsert the pin. Make
sure the jack is secured in place prior to towing.
WARNING
!
This equipment may be tongue heavy. DO NOT
attempt to raise or lower the drawbar by hand if
the weight is more than you can safely handle.
9. If a caster wheel is provided on the screw jack
it is part of the screw jack and can not be re-
moved. Follow the same procedure for stowing
away the wheeled jack as you would for the
standard screw jack. Raise the screw jack to its
full up position and pull the pin connecting the
jack to the drawbar. Rotate the screw jack to its
stowed position, parallel to the drawbar, and re-
insert the pin. Make sure the jack is secured in
place prior to towing.
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 drawbar or if hinged, to raise it to
the upright position, by hand, if the weight is
more than you can safely handle. Use a screw-
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-
and disconnect

curely latched in the vertical upright position.
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 parked 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.
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 29 CFR
1926.302 (b) (7) or any applicable Federal, State
and Local codes, standards and regulations.
C. When the hose is to be used to supply a mani-
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. DO NOT 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 antifreeze compound.
