SECTION 1
Lower front screw jack and/or any front and rear H. 
stabilizer legs. Make sure the surface they contact 
has sufcient load bearing capability to support the 
weight of the compressor.  
If a caster wheel is provided on the screw jack, it is I. 
part of the screw jack and cannot be removed. 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 upright 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.
Disconnect coupling device, keeping hands and J. 
ngers clear of all pinch points. If the compressor is 
provided with a drawbar, DO NOT attempt 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 screwjack or chain fall if you cannot lift 
or raise the drawbar without avoiding injury to 
yourself or others.
When possible, stow hinged drawbar in the vertical K. 
upright position. Make certain it is securely 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.
Move the towing vehicle well clear of the parked L. 
compressor and erect hazard indicators, barricades 
and/or ares (if at night) if compressor is parked on or 
adjacent to public roads. Park so as not to interfere 
with trafc.
PRESSURE RELEASE1.3 
Open the pressure relief valve at least weekly to A. 
make sure it is not blocked, closed, obstructed or 
otherwise disabled.
Install an appropriate ow-limiting valve between the B. 
compressor service air outlet and the shutoff (throttle) 
valve, when an air hose exceeding 1/2" (13 mm) 
inside diameter is to be connected to the shutoff 
(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.
When the hose is to be used to supply a manifold, C. 
install an additional appropriate ow-limiting valve 
between the manifold and each air hose exceeding 
1/2" (13 mm) inside diameter that is to be connected 
to the manifold to reduce pressure in case of hose 
failure.
Provide an appropriate ow-limiting valve for each D. 
additional 75 feet (23 m) of hose in runs of air hose 
exceeding 1/2" (13 mm) inside diameter to reduce 
pressure in case of hose failure.
Flow-limiting valves are listed by pipe size and rated E. 
CFM. Select appropriate valve accordingly.
DO NOTF.   use tools that are rated below the maximum 
rating of this compressor. Select tools, air hoses, 
pipes, valves, lters and other ttings accordingly. DO 
NOT exceed manufacturer’s rated safe operating 
pressures for these items.
Secure all hose connections by wire, chain or other G. 
suitable retaining device to prevent tools or hose 
ends from being accidentally disconnected and 
expelled.
Open uid ller cap only when compressor is not H. 
running and is not pressurized. Shut down the 
compressor and bleed the sump (receiver) to zero 
internal pressure before removing the cap.
 
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.  
NOTE
While not towed in the usual sense of 
the word, many of these instructions 
are directly applicable to skid- 
mounted portable air compressors as 
well. 
 
CAUTION
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.
On two-wheeled models, fully 
retract front screw jack and any rear 
stabilizer legs. 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 drawbar and raise the screw 
jack to its full up position. 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.
