WARNINGS
READ THIS PAGE
8/15/05
WARNING! Federal law (49 cfr part 571) requires that the Final Stage Manufacturer of a vehicle
certify that the vehicle complies with all applicable federal regulations. Any modifications performed
on the vehicle prior to the final state are also considered intermediate stage manufacturing and must
be certified as to compliance. The installer of this crane and body is considered one of the
manufacturers of the vehicle. As such a manufacturer, the installer is responsible for compliance
with all applicable federal and state regulations, and is required to certify that the vehicle is in
compliance.
WARNING! It is the further responsibility of the installer to comply with the OSHA Truck Crane
Stability Requirements as specified by 29 CFR part 1910.180 (C) (1).
WARNING! NEVER OPERATE THE CRANE NEAR ELECTRICAL POWER LINES!
Death or serious injury will result from boom, line, or load contacting electric lines. Do not use crane
within 10 feet (3.05m) of electric power lines carrying up to 50,000 volts. One-foot additional
clearance is required for every additional 30,000 volts or less. SEE DANGER DECAL (P/N 040529)
in this Owner's Manual.
WARNING! NEVER.........................................
♦EXCEED load chart capacities (centerline of rotation to hoist hook).
♦Un-reel last 5 wraps of cable from drum!
♦Wrap cable around load!
♦Attempt to lift or drag a load from the side! The boom can fail far below its rated capacity.
♦Weld, modify, or use unauthorized components on any Auto Crane unit! This will void any
warranty or liability. Also failure of the crane may result.
♦Place a chain link on the tip of the hook and try to lift a load!

INTRODUCTION
1-1.0 03/15/07
Auto Crane products are designed to
provide many years of safe, trouble-free,
dependable service when properly used and
maintained.
To assist you in obtaining the best service
from your crane and to avoid untimely crane
and/or vehicle failure, this manual provides
the following operating and service
instructions. It is specifically recommended
that all operating and service personnel
consider this manual as mandatory material
for reading and study before operating or
servicing Auto Crane products. It is highly
recommended that crane owners, equipment
managers, and supervisors also read this
manual.
Auto Crane has incorporated several safety
features in the 2003 crane for your
protection.
For your convenience the overall
dimensions of the 2003 crane are included
on the General Dimension Drawing.
Rotation and turning radius are also listed
on that drawing.
Remember, the crane adds weight to the
vehicle. Adding weight may change the
driving and riding characteristics of the
vehicle unless the appropriate overload
spring(s) are installed on the truck. The
payload of the vehicle is reduced by the
weight of the crane. The operator should
exercise care when loading the vehicle.
Distributing the payload on the vehicle
evenly will greatly improve the driving and
riding characteristics of the vehicle.
Auto Crane Company issues a limited
warranty certificate with each unit sold.
See last page for warranty.
The 2003 cranes are attached to your truck
electrical system through the Main Power
Switch provided. The 2003 is another highly
efficient Auto Crane product. The use of a
maintenance-free battery is not
recommended on any Auto Crane product.
The recommended alternator and battery
that will give the longest life with the most
useful duty cycle is a 75-amp alternator with a
500 cold cranking amp battery. These
specifications should be considered minimum.
It has always been Auto Crane Company
policy to handle all warranty claims we receive
as promptly as possible. If a warranty claim
involves discrepant material or workmanship,
Auto Crane will take immediate corrective
action. It is understandable that Auto Crane
Company cannot assume responsibility of
liability when it is obvious that our products
have been abused, misused, overloaded or
otherwise damaged by inexperienced persons
trying to operate the equipment without
reading the manual.
Auto Crane will not assume responsibility
or liability for any modifications or
changes made to unit, or installation of
component parts without authorization.
Auto Crane maintains a strong distributor
network and a knowledgeable Customer
Service Department. In most cases, an
equipment problem is solved via phone
conversation with our customer service
department. The customer service department
also has the ability to bring a local distributor,
a regional sales manager, or a factory
serviceman into the solution of an equipment
problem.
If, through no fault of Auto Crane Company, it
is necessary to send an experienced factory
serviceman on a field service call the rates
stated in the Auto Crane Distributor's Flat Rate
Manual will apply.
Auto Crane Company's extensive Research
and Development Program allow our
customers to use the best equipment on the
market. Our Engineering Staff and our
knowledgeable sales people are always
available to our customers in solving crane
and winch-type application problems. When in
doubt, call the Auto Crane factory.
Note: This manual should remain with the
crane at all times.

SAFETY TIPS AND PRECAUTIONS
2-1.0 10/16/06
1. No unqualified or unauthorized person shall be
allowed to operate the crane.
2. WARNING: Never weld, modify, or use
unauthorized components / parts on any Auto
Crane unit. This will void any warranty or
liability. Also, failure of the crane may result.
3. Make certain the vehicle meets minimum
chassis requirements. (These requirements do
not guarantee unit stability.)
4. Make certain the crane is installed per factory
specifications. Contact your local distributor or
the Auto Crane factory if any questions arise.
5. Visual inspections and tests should be
conducted at the beginning of each shift each
day to insure that the crane and all its operating
systems are in good condition and working order
before it is used.
6. Inspect hydraulic hoses frequently for signs of
deterioration, and replace them as required.
7. If a hydraulic break occurs, leave the area of the
break and do not attempt to stop the break by
hand as the hydraulic oil may be hot and under
high pressure which can cause serious injury.
Shut the system down as soon as possible.
8. Check the hook at least every thirty days for
distortions or cracks and replace it as required.
9. Oil gears as required.
10. Stop all operations when cleaning, adjusting or
lubricating the machine.
11. Keep dirt and grit out of moving parts by keeping
crane clean. Make sure machine is free of
excess oil, grease, mud and rubbish, thus
reducing accidents and fire hazards.
12. When a new cable is installed, operate first with
a light load to let the cable adjust itself.
13. Locate the vehicle at the work site for the best
stability possible.
14. Keep the vehicle in a level position while loading
or unloading.
15. Observe operating area for obstructions and/or
power lines that might be a hazard.
16. WARNING: NEVER OPERATE THE CRANE
NEAR ELECTRICAL POWER LINES. Auto
Crane Company recommends that the crane
never be any closer to a power line (including
telephone lines) than 10 feet at any point.
17. Allow the vehicle engine to warm up before
operating crane.
18. Know the weight of your rigging and load to
avoid overloading the crane.
19. Deduct the weight of the load handling
equipment from the load rating to determine how
much weight can be lifted.
20. All load ratings are based on crane capacity,
NOT the vehicle stability. Remember in lifting a
heavy load, the weight can create enough
tipping moment to overturn the vehicle
21. Always comply with load chart capacities,
(centerline of rotation to hook).
22. Secure all loads before lifting.
23. Always set the emergency brake before
beginning operation.
24. Keep objects and personnel clear of crane path
during operation.
25. Operate control levers slowly and smoothly in
order to meter oil flow for safe operation.
(Not applicable to electric-hydraulic cranes.)
26. Always extend the outriggers from vehicle to the
ground before crane operation. Insure that they
are firmly positioned on solid footings. Stand
clear of outriggers while they are being
extended.
27. If any outrigger, when extended, rests on a curb
or other object that prevents it from extending to
its maximum distance, shorten bearing or
fulcrum point and reduce the maximum load
accordingly.
28. When an outrigger will not reach the ground due
to holes or grades, it shall be blocked up to
provide level and firm support for the truck.
29. When working in soft earth, use wide pads
under outrigger feet to prevent sinking.
30. Always store outriggers before transportation.
WARNING!
Auto Crane Company cranes are not designed or intended for use in lifting or moving persons. Any
such use shall be considered to be improper and the seller shall not be responsible for any claims
arising there from. This sale is made with the express understanding that there is no warranty that
the goods shall be fit for the purpose of lifting or moving persons or other improper use and there is
no implied warranty or responsibility for such purposes.

SAFETY TIPS AND PRECAUTIONS
2-2.0 10/16/06
31. Always store the crane in its stowed position
for transportation.
32. Remember the overall height of the entire
unit for garage door clearance or when
moving under objects with low overhead
clearance
33. Disengage power takeoff (PTO) before
moving the vehicle.
(Not applicable to electric-hydraulic cranes.)
34. Always walk around the vehicle before
moving.
35. Never drive with a load suspended from
crane.
36. Do not take your eyes off a moving load.
Look in the direction you are moving.
37. Never swing a load over people.
38. Do not stop the load sharply in midair so that
it swings like a pendulum. Meter the control
levers to avoid this situation.
(Not applicable to electric-hydraulic cranes.)
39. Crane boom length should be kept as short
as possible for maximum lifting capacity and
greater safety. Longer booms require
additional care in accelerating and
decelerating the swing motion, and thus slow
down the working cycle and reduce
productivity.
40. Keep the load directly and vertically under
the boom point at all times. Crane booms
are designed to handle vertical loads, not
side lifts.
WARNING: Never attempt to lift, drag, tow or
pull a load from the side. The boom can fail
far below its rated capacity.
41. Do not push down on anything with boom
extensions; similarly do not lift anything with
boom extensions.
42. Do not lift personnel with any wire rope
attachment or hook. There is no implied
warranty or responsibility for such purposes.
43. WARNING: In using a safety hook, ALWAYS
close the hook throat before lifting a load.
Proper attention and common sense applied
to the use of the hook and various slings will
prevent possible damage to material being
hoisted and may prevent injury to personnel.
44. WARNING: Never place a chain link on the
tip of the hook and try to lift a load with the
hoist.
45. WARNING: Never use a sling bar or
anything larger than the hook throat which
could prevent the safety latch from closing,
thus negating the safety feature.
46. Do not wrap the wire rope around sharp
objects when using winch.
47. WARNING: Never unreel last 5 wraps of
cable from drum.

above.
EXCEPTIONS
A. The danger zone may be entered after
confirmation by an appointed person that the
electrical distribution and transmission lines
have been de-energized and visibly
grounded at the point of work; or
B. The danger zone may be entered if
insulating barriers (not a part of nor an
attachment to the crane) have been erected
to prevent physical contact with the lines.
2. For lines rated 50 kV or below, minimum
clearance between the lines and any part of the
crane or load (including handling appendages)
shall be 10-ft. (3m). For higher voltages, see
Table 1.
3. Caution shall be exercised when working near
overhead lines, because they can move
horizontally or vertically due to wind, moving the
danger zone to new positions.
4. In transit with no load and boom lowered the
clearance shall be specified in Table 1.
5. A qualified signalperson shall be assigned to
observe the clearance and give warning before
approaching the above limits.
A. Any overhead wire shall be considered to be an
energized line unless and until the person
owning such line or the electrical utility
authorities verify that it is not an energized line.
B. Exceptions to this procedure are allowed, if
approved by the administrative or regulatory
authority provided the alternate procedure
insures equivalent protection and is set forth in
writing.
C. Durable signs shall be installed at the operator's
station and on the outside of the crane, warning
that electrocution or serious bodily injury may
occur unless a minimum clearance of 10 ft.
(3.0m) between the crane or the load being
handled and energized power lines. Greater

OPERATION OF UNIT
2-7.0 8/19/05
1. Make sure this manual has been thoroughly
read by all crane operating personnel and
supervisors.
2. A routine inspection of the crane should be
mandatory before each operating day. Any
defects should be corrected immediately.
3. At a job site the vehicle should be positioned so
that the crane can adequately reach the load
within the rated capacity (centerline of rotation
to hoist hook).
4. Keep the vehicle as level as possible during
operation.
5. For electric cranes, engage emergency brake
and leave ignition on with transmission in
neutral (or in park for automatic transmissions).
Activate any crane power switches. For Auto
Crane units requiring battery and hydraulic
operation, engage emergency brake, place
gear selector in neutral, press clutch, activate
PTO, release clutch and after hydraulic fluid is
warm, set throttle control to proper engine
speed.
6. Always use outriggers from the truck to the
ground. Be sure these are firm and adequately
positioned. When rotating, keep load as low to
the ground as possible.
7. Remove the transmitter from cab or storage
area. Power transmitter on. Detach hook from
dead man. Crane is now ready for operation.
8. Always boom up before rotating so the boom will
clear the required boom support.
9. When extending the boom, always maintain
clearance between the boom crown and the
traveling block or hoist hook.
10.Always observe safe and practical operation to
avoid possible accidents. Refer to Safety Tips
and Precautions.
11.After completing lifting operations, return the
boom to stowed position on the boom support.
Avoid unneeded pressure on the boom support.
12.Store transmitter in proper location (in cab or
storage area).
13.Return outriggers to stowed position. Make sure
they are pinned in place or jacklegs are returned
to compartment.
14.Check work area for any tools or equipment not
stored.
15.Release throttle control, depress clutch and
disengage PTO. Deactivate any crane power
switches.
16.Report any unusual occurrence during crane
operation that may indicate required maintenance
or repair.
17.NEVER use two cranes to support a load too
large for either crane.
OPERATION OF
OUTRIGGERS
HYDRAULIC OUTRIGGERS
1. Shift crane/outrigger control valve to
