Inspect for Damage, Loose or
Missing Parts
Daily machine condition inspections are essential
to safe machine operation and good machine
performance. Failure to locate and repair damage,
and discover loose or missing parts may result in
an unsafe operating condition.
1 Inspect the entire machine for damage and
improperly installed or missing parts including:
· Electrical components, wiring and electrical
cables
· Hydraulic power unit, hoses, fittings,
cylinders and manifolds
· Turntable motor and worm gear
· Boom components and wear pads
· Dents or damage to machine
· Tires and wheels
· Limit switches
· Service horn
· Alarm and beacon package (if equipped)
· Nuts, bolts and other fasteners
· Platform entry mid-rail
· Cracks in welds or structural components
· Compartment covers and fasteners
· Battery packs and connections

Check the Hydraulic Oil Level
Maintaining the hydraulic oil at the proper level is
essential to machine operation. Improper hydraulic
oil levels can damage hydraulic components. Daily
checks allow the inspector to identify changes in
oil level that might indicate the presence of
hydraulic system problems.
1 Be sure that the boom is in the stowed position.
2 Visually inspect the sight gauge on the
hydraulic power unit reservoir.
Result: The hydraulic oil level should be visible
inside the sight gauge.

Check for Hydraulic Leaks
Detecting hydraulic fluid leaks is essential to
operational safety and good machine
performance. Undiscovered leaks can develop into
hazardous situations, impair machine functions
and damage machine components.
1 Inspect for hydraulic oil puddles, dripping or
residue on or around the following areas:
· Hydraulic power unit—fittings, hoses
and turntable surface
· Drive motor compartment—brakes, fittings,
hoses, and compartment surface
· All hydraulic cylinders
· All hydraulic manifolds
· Primary and secondary booms
· The underside of the turntable
· The underside of the drive chassis
