General Operation
WARNING
Safety should be the n umber one thought on every operator’s mind. Three factors should
exist for safe operation: a qualified operator, well-maintained equipment, and the proper
use of this equipment.
This chapter contains information regarding the safety and operation of Stellar®
manufactured EC Series Telescopic Cranes and should be read and understood
completely by everyone working with or near the crane before putting the unit into
operation.
ailure to follow operating, maintenance, or safety instructions can
result in death or serious injury.
Chapter 1 - Operation
WARNING

St llar® EC S ri s Cran Own r’s Manual
The drive axle must be disengaged and the parking brake must be set before operating
any of the equipment.
To initiate electrical power to the crane, activate the button labeled ‘Main Power’, usually
located in the cab of the truck.
Step 2: Turn on power to the crane.
Step 1: Disengage drive axle and set the parking brake.
Thoroughly plan the lift by understanding the work site area and your loads before
positioning the vehicle. or a complete and detailed description of job site setup, please
refer to the AEM Safety Manual ( orm C-70-2). Consider the following:
• The vehicle should be positioned in an area free from bystanders and overhead
obstructions. Use a signal person if necessary.
• Always maintain safe clearance from high voltage power lines in
accordance with ANSI B30.5: 5-3.4.5 Op rating N ar El ctric Pow r Lin s. Death or
serious injury will result from inadequate clearance if crane, load, or vehicle becomes
electrically charged.
• Make certain that the vehicle is parked on stable, flat ground as close to the job as
possible. The surface under the service truck must be able to support the weight of the
machine and its load.
• Use wheel chocks if parking the vehicle on a slope.
•Always park the vehicle with the grade. If cross-grade parking is required, the load
capacity must be decreased appropriately to mitigate tipping risk.
• Do not operate the crane during electrical storms.
• In dusty work areas, every effort must be taken to keep dust and sand out of the moving
parts of the machinery.
• In high humidity work areas, keep parts as dry as possible and well lubricated.

auxiliary battery recharge instructions.
Replace/repair as necessary prior to operation. or a more detailed checklist of
scheduled inspection points, refer to the Stellar®Crane Inspection Log. This document is
an essential guide for the daily, monthly, quarterly and annual inspection tasks that will
help maintain the quality of your Stellar product.

Op ration 
Step 4: Operate the crane.
Operators should have a firm understanding of ANSI B30.5 - S ction 5-3.2 Op rating
Practic s and AEM Saf ty Manual (Form C-70-2) prior to operating of the crane.
The truck should always remain running while operating the crane to
maintain battery charge. Stellar recommends the use of an auxiliary battery when
operating the crane indoors or in an environment that prevents to the truck from running.
Using the Radio Remote:
To operate the crane using the radio remote control, activate the desired toggle function.
The radio remote allows for simultaneous functions. With practice, it is possible to use more
than one toggle at the same time (Extension Out/Winch Down for example). See the
Radio Remote Control unctions and eatures pages later in this chapter for more
information.
Unstowing the Crane:
To unstow the crane and prepare it for a lift:
• Winch down slightly.
• Raise the boom high enough to clear the boom rest and any other obstructions from the
chassis.
• Rotate the crane until it clears the side of the truck body.
• Lower the crane boom down far enough so that the snatch block is within comfortable
reach.
• Winch down to create slack in the wire rope and unhook the snatch block.
NOTICE
Lower the stabilizer(s) using the hand crank located at the rear of the truck.
Keep clear of stabilizer legs during operation. Moving stabilizers can
cause serious crushing injuries. Make certain that all personnel are clear of the stabilizer
and the ground contact point before operating.
Do not raise the rear tires of the truck off the ground with the stabilizers.
Confirm that the stabilizers are positioned on stable, flat ground and that the truck is as
level as possible both front to rear and side to side. Use stabilizer pads to ensure the
proper distribution of weight.
Step 3: Position the stabilizers.
WARNING
WARNING

St llar® EC S ri s Cran Own r’s Manual
Attaching the load:
• Position the crane with the hook centered directly over the load avoid side loading.
• Attach the load to the hook by means of slings or other approved devices.
Never use a sling bar or anything larger than the hook throat that
could prevent the hook latch from closing. This would negate the safety feature.
• Maintain a minimum of 3 full wraps of wire rope on the winch drum at all times.
Do not wrap the wire rope around the load.
Lifting the load:
Lift the load slightly off the ground to check the safety of the cargo. Consider the
following:
• Make certain that the stabilizers are positioned on flat, stable ground.
• Never exceed manufacturer’s load charts and ratings. These ratings
are based on the machine’s hydraulic, mechanical, and structural design rather than
stability.
• It is the responsibility of the operator to know the weight of both the rigging and the
handled load to avoid overloading the crane. Do not rely on the overload device to
determine maximum rated loads. If the crane is picking more than the maximum rated
load, the overload protection device may be malfunctioning. Discontinue use
immediately and contact Stellar Customer Service for support.
• Do not use a crane to lift personnel.
• Do not attempt to lift fixed loads.
Moving the load:
Ensure that the load is secure and balanced within the sling before moving. Consider the
following:
• Be sure that the crane is level and stable before moving the load.
• Always look for any changes to the surroundings since the job site setup. Be aware of
any new or missed overhead obstructions (branches, power lines, etc) and bystanders.
Use a signal person if necessary.
• Never operate the crane with personnel under any part the boom or
load. Do not extend or rotate a load over anyone. Never allow personnel to place
themselves under any part of the boom or load.
• Never leave a crane load suspended or unattended.

tasks that will help maintain the quality of your Stellar product.
Maintenance is an important part of extending the life of any Stellar®Telescopic Crane.
Performing key maintenance items on a scheduled program will prevent unnecessary
downtime.
Basic Crane Maintenance Schedule*

 St llar® EC S ri s Cran Own r’s Manual
While operating the crane, extend and retract the extension booms. If the extension
weldments are noisy during operation, it is necessary to lubricate the booms. Stellar®
Model Cranes feature a metal coating which will require an aerosol lubricant. Stellar
Industries recommends aerosol style lubricant Stellar PN 44512.
Extension Boom Maintenance
Refer to winch manual supplied with crane.
Winch Maintenance
Proper maintenance is key in ensuring a long lasting rope. Refer to ANSI B30.5 for details on
maintaining your wire rope.
Wire Rope Maintenance
Washing the Crane
Important: Prior to washing the Stellar crane, the radio remote receiver located on the
crane mast must be covered to prevent any water from entering the plastic housing.
Avoid any direct water pressure to the radio remote receiver.
Add hydraulic oil as needed. Stellar Industries recommends the hydraulic oil be changed
after 6,500 hours.
• Do not disconnect hydraulic hoses while there is still pressure in those
components.
• Replace parts with Stellar® approved parts only.
• Keep the crane and service body clean and free from grease build-up, oil and dirt to
prevent slippery conditions.
• Label or tag parts when disassembling.
• Immediately repair or have repaired any components found to be inadequate.
Hydraulic Oil Maintenance
Recharging the Auxiliary Battery
To recharge the auxiliary battery, engage the battery charge switch (located in the truck
cab or the crane box) while the truck is running. When operating the crane while the
truck is not running, disengage the battery charge switch to prevent the crane from
draining the main truck battery.
WARNING

Maint nanc 
Rotation Gear Bearing Maintenance
Rotation Worm Gear and Open Gear Teeth
Use a heavy Moly Lube grease (Stellar PN
4460) to lubricate the worm gear and open
gear teeth of the rotation bearing. Slowly
rotate the crane while pumping the grease
between the worm and rotation gear. This
should be greased every month or sooner
depending on the usage of the crane.
Another way of applying the grease would
be to remove the gear guard and brush the
Molube grease between the gear teeth of
the rotation bearing.
Do not lubricate the worm
and rotation gear teeth with EP2 grease. EP2
grease will wipe the Molube grease clean
causing excessive wear.
Worm Gear Bearings and Races
Apply three (3) pumps of EP2 grease to the
two grease zerks located on the side of the
Rotation Gear bearing; every three months.
After adding the EP2 grease, rotate the
crane fully.
Inner Gear Bearing Race
To lubricate the inner race of the large rota-
tion gear bearing, open the compartment
door just below the crane. The grease zerk
for the inner race bearing is located on the
compartment drip tray. The inner race will
need to be lubricated with EP2 Grease
weekly. The first week grease the inner race
bearing at the one (1), three (3), five (5),
seven (7), nine (9), and eleven (11) o’clock
positions. The following week, grease the
inner race bearing in the two (2), four (4), six
(6), eight (8), ten (10) and twelve (12)
o’clock positions. Rotate lubrication points
every week.

Once a bolt has been torqued to 75% of its proof load and then removed, the torque
coefficient may no longer be the same as when the bolt was new thus giving
indeterminate damp loads after torquing.
