Before performing any maintenance to the
crane, consider the following:
•
Only qualified service
personnel are to perform
maintenance on the crane. Never modify or
alter any of the equipment, whether me-
chanical, electrical, or hydraulic, without ex-
plicit approval from Stellar
®
Industries.
• Position the crane where it will be out of the
way of other operations or vehicles in the area.
• Lower the boom fully or stow in the cradle to
prevent uncontrolled movement.
• Place all controls in the off position and se-
cure operating features from inadvertent mo-
tion. Follow all company directed lockout/
tagout procedures.
• Before any service or repair is performed, dis-
engage the hydraulic power source and shut
off the engine.
• Allow systems to cool before performing any
maintenance.
• Before performing any maintenance on elec-
trical components, disconnect the power
source.
• Before performing any maintenance on hy-
draulic components, relieve hydraulic oil pres-
sure from all hydraulic circuits. Move pedals
and control levers repeatedly through their
operating positions to relieve all pressures.
•
Do not disconnect hy-
draulic 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 pre-
vent slippery conditions.
• Label or tag parts when disassembling.
• Immediately repair or have repaired any
components found to be inadequate.
