Maintenance
WEEKLY CHECKS
The following weekly checks should be performed in addition to the daily checks:
1. Check mechanical linkages for signs of wear or binding. Lubricate as necessary with 10 weight
motor oil.
2. With all boom sections retracted, move boom side to side and check for missing wear pads between
boom sections and excess clearance or looseness in rotation gearbox (more than 2”-4” of play side
to side at boom tip).
3. If machine is salt covered, wash weekly to prevent rust and corrosion.
4. Do weekly lubrication.
MONTHLY OPERATIONAL CHECKS
The following checks should be performed monthly in addition to the daily and weekly checks:
1. Check oil level in the rotation gearbox. It should be filled with HD-80W90 to the fill plug. At this time
a shot of grease should be added to the grease zerk on the upper bearing. (Caution: Do not
overgrease this bearing!)
2. Check for excessive movement in the rotation gear mechanism. If over 4” of movement (side to
side) is detected by moving the boom tip back and forth when fully retracted, it would be considered
excessive.
3. Inspect all crane mounting bolts for signs of looseness or breakage. Replace or retorque where
necessary. (see Torque Specs - SAE & Metric on page 361 ).
4. Extend all boom sections and check for physical defects, cracks and signs of overstress. Check
the boom while extending to make sure it is properly sequencing. With the boom fully extended,
check for excessive droop. Check to make certain all boom wear pads are in place and tight, and
no excessive slop between boom sections is detected.
5. Check that all boom and outrigger pins are properly secured and make certain that keepers and
snap rings are present and properly installed.
6. Inspect load line for signs of kinking, crushing, cutting, or other damage.
7. Inspect weldments for signs of cracks at weld joints on all structural members.
8. Change hydraulic oil filter.
