2 10621 Owner’s Manual
STABILITY
Know the crane components and their
capabilities and limitations. Overloading the
crane may r
esult in serious injury to self and
others, and damage to the equipment and
immediate surroundings.
Never exceed manufacturer’s load ratings.
These ratings are based on the machine’s
hydraulic, mechanical, and structural design
rather than stability.
The supporting surface under the service truck
must be able to support the weight of the
machine and its load. Use outrigger pads if
necessary.
Park the vehicle on level ground and extend
the outriggers fully out and then down.
Keep feet and legs clear when lowering
outrigger jacks.
Never operate the crane without making sure
the outriggers are positioned on stable, flat
ground.
Set the parking brake and disengage the
drive axle before attempting a lift.
LOAD SAFETY
Operate the crane in compliance with the
load capacity chart at all times. Know the
weight of the load being lifted. Do not rely on
the overload device to deter
mine 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.
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.
Do not apply side loads to the booms.
Do not leave a crane load suspended or
unattended.
Do not walk under suspended loads.
Do not position any load over a person nor
should any person be permitted to place him
or herself under a load.
Do not use the boom or the winch to drag a
load.
Do not use the crane boom to push
downward onto anything.
ELECTROCUTION
Allow extra space for swaying power lines in
windy conditions.
Keep a minimum of ten feet between any
portion of the crane and an electrical line.
Add an additional 12" for every additional
30,000 V
olts or less.
Remember - Death or serious injury can occur
when working near power lines or during
electrical storms.
Use a signal person when operating near
electrical sources.
ENVIRONMENT
Do not operate the crane during electrical
stor
ms.
In extreme cold, allow adequate time to
warm the truck before engaging the PTO. Do
not rev the truck engine and over speed the
hydraulic pumps as permanent damage to
the pumps may occur. Follow the vehicle
owner’s manual regarding operating the
vehicle in such adverse conditions.
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.
