Every six (6) months, remove the hydraulic pump from the PTO and lubricate the splines
using Chelsea Lubricant #379831 or Stellar PN 42042 (packet) or PN 20885 (lube). Failure to
lubricate shaft splines will cause damage to the PTO and Hydraulic pump.
PTO and Pump Maintenance
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.
Hydraulic Oil/Filter Maintenance
Before performing any maintenance to the autotarper, consider the following:
• Only qualied service personnel are to perform maintenance on the
autotarper. Never modify or alter any of the equipment, whether mechanical, electrical,
or hydraulic, without explicit approval from Stellar Industries.
• Position the autotarper where it will be out of the way of other operations or vehicles in
the area.
• Make certain that the autotarper is in the fully stowed position to prevent uncontrolled
movement.
• Place all controls in the off position and secure operating features from inadvertent
motion.
• When checking hydraulic oil level, make certain that all system cylinders are fully
retracted.
• Grease zerk locations can be found in the Installation, Assembly Drawings, Parts Manual.
• Before any service or repair is performed, disengage the PTO and shut off the engine.
• Before performing any maintenance on electrical components, disconnect the power
source.
• Before performing any maintenance on hydraulic components, relieve hydraulic
oil pressure from all hydraulic circuits. Move control levers repeatedly through their
operating positions to relieve all pressures.
• Do not disconnect hydraulic hoses while there is still pressure in those
components.
• Replace parts with Stellar
®
approved parts only.
• Keep the autotarper 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.
