Heavy-Duty Telescopic Crane Owner’s Manual
Stellar Industries recommends the rst lter change to occur after the rst 250 hours of service.
The second, and every subsequent change, should occur after every 1,000 hours of service. By
following these guidelines, the hydraulic oil should last up to 6,500 hours.
Note: These recommendations are based on normal working parameters. If operating in less than
favorable conditions excessive dust, moisture, etc.), be sure to check the lter gauge often for lter
change notice.
Important: Prior to washing the Stellar crane, all electrical components must be covered to prevent
any water from being injected into the plastic housing. Avoid any direct water pressure to any of
the electrical components.
Touch up any chips or scratches to prevent further paint damage.
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.
Fully extend a load (65-70% of crane’s rated capacity) at a boom angle of approximately 60º.
With the load at 3-5 inches off the ground, use a tape measure to mark the load from a specic
at/level spot on the ground (Note: Use a board/pad if necessary). Also at this time, use a grease
pen to make a temporary mark on the main cylinder rod and another mark on the winch drum in
reference to the housing. Finally, measure the stabilizer legs from the ground.
After waiting ve minutes, measure the load from the same specic spot on the ground. If the load
movement is within 1/4”, the test has passed. If the load has moved more than 1/4”, wait another
ve minutes and re-measure. If the load continues to move, check the other marks (main cylinder
rod, winch drum) and re-measure the stabilizers to narrow down the potential drifting issue. Please
refer to the troubleshooting section at the end of this manual for further detailed instructions.
Every six (6) months, remove the hydraulic pump from the PTO and lubricate the splines using Stellar
PN 20885. Failure to lubricate shaft splines will cause damage to the PTO and Hydraulic pump.
Proper maintenance is key in ensuring a long lasting rope. Refer to ANSI B30.5 for details on
maintaining your wire rope.
Refer to winch manual supplied with crane.
