H. On two-wheeled models, fully retract front screw jack 
and any rear stabilizer legs. If a caster wheel is pro-
vided 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 
upright 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 tow-
ing.
I. Make sure tires are in good condition and are the 
size (load range) specified and are inflated to the 
specified pressures. DO NOT change the tire size or 
type. Also, make sure wheel bolts, lugs or nuts are 
tightened to the specified torques.
J. If provided, make sure all dual stop, tail directional 
and clearance lights are operating properly and that 
their lenses are clean and functional. Also, make 
sure all reflectors and reflecting surfaces, including 
the slow moving vehicle emblem on compressors 
provided with same, are clean and functional.
K. Make sure all service air hoses (not air brake hoses) 
are disconnected or are fully stowed and secured on 
hose reels, if provided.
L. Make sure all access doors and tool box covers are 
closed and latched. If the compressor is large 
enough to hold a man, make sure all personnel are 
out before closing and latching access doors.
M. Make sure parking brakes in towing vehicle are set, 
or that its wheels are chocked or blocked, or that it is 
otherwise restrained from moving. Then, release the 
compressor parking brakes, if provided.
N. Make sure the compressor wheels are not chocked 
or blocked, and that all tie-downs, if any, are free.
O. Test running brake operation, including breakaway 
switch operation if provided, before attempting to tow 
the compressor at its rated speed or less when con-
ditions prevail.
P. DO NOT carry loose or inappropriate tools, equip-
ment or supplies on or in the compressor.
Q. DO NOT load this equipment with accessories or 
tools such that it is unbalanced from side to side or 
front to back. Such unbalance will reduce the towabil-
ity of this equipment and may increase the possibility 
of tipping, rolling over, jackknifing, etc. Loss of control 
of the towing vehicle may result.
1.13.2 Towing 
A. Observe all Federal, State, and Local laws while tow-
ing this equipment (including those specifying mini-
mum speed).
B. DO NOT exceed the towing speeds listed below 
under ideal conditions. Reduce your speed according 
to posted speed limits, weather, traffic, road or terrain 
conditions:
C. Two axle four-wheel or three axle six-wheel steerable 
models: 15 mph (24 km/h).
D. All other models: 55 mph (88 km/h).
E. Remember that the portable air compressor may 
approach or exceed the weight of the towing vehicle. 
Maintain increased stopping distances accordingly. 
DO NOT make sudden lane changes, U-turns or 
other maneuvers. Such maneuvers can cause the 
compressor to tip, roll over, jackknife or slide and 
cause loss of control of the towing vehicle. Tipping, 
rolling over, etc. can occur suddenly without warning. 
U-turns especially should be made slowly and care-
fully.
F. Avoid grades in excess of 15° (27%).
G. Avoid potholes, rocks and other obstructions, and 
soft shoulders or unstable terrain.
H. Maneuver in a manner that will not exceed the free-
dom of motion of the compressor’s drawbar and/ or 
coupling device, in or on the towing vehicle’s cou-
pling device and/or adjacent structure whether tow-
ing forward or backing up, regardless of the terrain 
being traversed.
I. DO NOT permit personnel to ride in or on the com-
pressor.
J. Make sure the area behind, in front of, and under the 
compressor is clear of all personnel and obstructions 
prior to towing in any direction.
K. DO NOT permit personnel to stand or ride on the 
drawbar, or to stand or walk between the compressor 
and the towing vehicle.
1.13.3 Parking or locating compressor
A. Park or locate compressor on a level surface, if pos-
sible. If not, park or locate compressor across grade 
so the compressor does not tend to roll downhill. DO 
NOT park or locate compressor on grades exceeding 
15° (27%).
B. Make sure compressor is parked or located on a firm 
surface that can support its weight.
