Introduction
This manual includes parts, specifications, and installation information for your particular crane.
It is your responsibility to maintain and operate this unit in a manner that will result in the safest
working conditions possible.
Warranty of this unit will be void on any part of the unit subjected to misuse due to overloading,
abuse, lack of maintenance and unauthorized modifications. No warranty - verbal, written or
implied - other than the official, published IMT new machinery and equipment warranty will be
valid with this unit. In addition, it is also the user’s responsibility to be aware of existing Federal,
State and Local codes and regulations governing the safe use and maintenance of this unit. This
crane was designed and built to meet the standards of ANSI/ASSE A10.31-1995, Safety
Requirements, Definitions, and Specifications for Digger Derricks. Contact the American
National Standards Institute (www.ansi.org) for more information.
Throughout this manual, three means are used to draw the attention of personnel. They are
NOTEs, CAUTIONs and WARNINGs and are defined as follows:
NOTE
A NOTE is used to either convey additional information or to provide further emphasis for a
previous point.
CAUTION
A CAUTION is used when there is the very strong possibility of damage to the equipment or
premature equipment failure.
WARNING
A WARNING is used when there is the potential for personal injury or death.
For optimum safety, treat this equipment with respect and service it regularly.

Safety
WARNING
KEEP CHILDREN, BY-STANDERS, AND PERSONS NOT REQUIRED IN THE OPERATION
OF EQUIPMENT AT LEAST 10’-0” (3.05 m) FROM THE OUTERMOST RANGE OF THE
CRANE.
CRANE OPERATION
Make sure the chassis is rated to withstand the crane weight and load moment.
Know the position of the booms at all times while operating the crane.
Eliminate swing by positioning the boom tip directly over the center of the load before lifting.
Never drag a load.
Check the safety of the load by first lifting the load barely off the ground.
Stop all crane operation at a signal from anyone.
When you rotate the crane, the load may change from being supported by the outriggers to
the vehicle suspension. Be cautious as you rotate the crane, because the springs on the
carrier vehicle will respond differently to the load than the tires will.
Position the crane in its stowed position when not in use.
FIRE PRECAUTIONS
To avoid fires,
Use safety-type portable gasoline containers equipped with an automatic closing cap and
flame arrester.
DO NOT refuel while the vehicle engine is running.
DO NOT smoke in a refueling area.
Install in the vehicle cab a portable fire extinguisher with a basic minimum extinguisher rating
of 10 BC and know how to use the fire extinguisher.
READ THE ENTIRE MANUAL BEFORE OPERATING THE CRANE.
Use this manual for reference and for training operators. This manual covers the basics of safe
and correct operation of your crane. However, success and safety depends greatly upon the
skill and caution of the person actually doing the work. Persons engaging in these procedures
do so entirely at their own risk.
Chapter 1 Introduction 7
Daily Safety Inspection
Using the Crane Log, IMT Manual No. 99900686, or the inspection checklist in the reference
section of this manual, inspect the crane on a daily, weekly, and monthly basis. Use the
following list as a guide when you are inspecting your unit at start-up and during operation:
1 Vehicle - Check oil level, battery, lights, brakes, and tires for inflation, pressure, cuts, and
loose or missing wheel lugs.
2 Safety Accessories - Check for proper function, oil levels, leaks and malfunctions.
3 Weldments - Check visually for damage, especially cracks or breaks in welds.
4 Fasteners - Check pins, sheaves, nuts and bolts for breakage, excessive wear and
tightness.
5 Crane Hooks - Check for the presence of a safety catch, twists, cracks, or damage.
6 Covers and Guards - Check for missing or improperly maintained covers and guards.
7 Operation Placards and Safety Decals - Check for illegible or missing decals and placards.
Refer to the decal section of this manual for more information on the required decals.
Replace or repair any items as needed prior to equipment operation.

SPECIAL FEATURES High pressure shaft seal
COLOR Gloss black
CYLINDER HOLDING VALVES
The base ends (extend sides) of the lower boom and extension cylinders are equipped with
integral-mounted counter-balance valves to prevent sudden cylinder collapse in case of hose or
other hydraulic failure.
The counter balance valves serve several functions. These include:
1 Holding valves
2 Speed control for the lowering function via which causes that function to be metered under
load
3 Prevention of excessive oil loss during a hose failure.
WINCH
The winch is powered by a hydraulic motor through a planetary gear with a mechanical brake.
Only single line is permitted. The maximum single line capacity is 3800 lb. The winch is
equipped with 1/2" diameter synthetic fiber rope.
HYDRAULIC SYSTEM
The six-section crane valvebank is operated by a radio remote control with a manual handle as a
back-up system. The handle is stored behind the cover on the mast.
