TC Series 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.
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.

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.
