LUBRICATION AND MAINTERNANCE
CAUTION:
Important:
CAUTION:
Refer to "Lubrication and Maintenance Chart" for quick reference to Maintenance Operations.
CAUTION:
CAUTION:
Operate the backhoe from the operator seat only.
CAUTION:
Check the tractor hydraulic system as outlined in the Tractor Operator's Manual.
Note:
Inspect hydraulic hoses, connections, control valve and cylinders for evidence of leakage.
When checking hydraulic system oil level, the backhoe should be on the ground and bucket fully
retracted(all cylinders in retracted position).
Grease all backhoe pivot points daily(10 hours). Refer to Tractor Operator's Manual for lubricant
recommendations.
Tractor tires should be maintained at maximum recommended inflation to maintain normal tire
profile with added weight of backhoe/material. Unequal rear tire inflation can result in bucket not
being level to the ground.
Do not perform service or maintenance Operations with backhoe raised off the ground. For
additional access to tractor components remove backhoe.
Lower the backhoe to the ground and relieve pressure in backhoe hydraulic lines prior to
performing any service or maintenance operations on the tractor or backhoe.
Escaping fluid under pressure can have sufficient force to penetrate the skin, causing serious
injury. Before disconnecting lines, be sure to relieve all pressure. Before applying pressure to the
system, be sure all connections are tight and that lines, pipes and hoses are not damaged. Fluid
escaping from a very small hole can be almost invisible. Use a piece of cardboard or wood
rather than your hands to search for suspected leaks. If injured by escaping fluid, seek medical
attention immediately. Serious infection or reaction can develop if correct medical treatment is
not administered immediately.
Do not operate the backhoe if the fittings are leaking or if the hoses are damaged. A sudden line
burst could cause the boom, dipperstick(arm) or bucket to drop suddenly, causing damage to
the tractor or backhoe or injury to personnel.
Do not stand or walk under a raised backhoe. Accidental movement of control lever or leak in
hydraulic system could cause boom or dipperstick(arm) to drop, causing severe injury.
