Maintenance Check List
• PIVOT: At start of irrigation season, grease pivot bearings. Repeat every 400 hours of
operation.
• GEARBOXES: At start of irrigation season, drain all gearboxes and refi ll with
recommended oil. See Power Drivetrain Maintenance section for detailed information. Refer
ence Section 1-10. and 1-11.
• MOTOR GEARBOXES: At start of irrigation season drain any water that may have
accumulated during the irrigation season and fi ll to the proper level with the proper lubricant.
Reference Section 1-12. and 1-13.
• TIRES: Check tire infl ation (use low pressure tire gauge). Pierce Corporation infl ates all
new tires to a higher pressure for truck loading requirements. Set tire pressure so side wall
has slight fl ex. If tire creases increase pressure. If tire pressure too low tires will lose bead and
damage the tube.
CAUTION: Operating tires below the manufacturers recommended pressure can
result in damage to the tire sidewall in addition to voiding your warranty.
• WHEEL BOLTS: Check to ensure they are tight.
Note: Wheel bolts can loosen after initial installation. They should be checked after 100
hours of operation.
• STRUCTURE: Routinely check pivot, span and tower structures for loose or missing bolts.
• CONNECTORS: Check for leaking gaskets, boots, drains, and malfunctioning sprinklers or
pressure regulators.
