LUBRICATION AND MAINTENANCE
Caution :
Do not perform service or maintenance operations with backhoe raised off the ground.
For additional access to tractor components remove backhoe.
Important:
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.
Caution :
Escaping fluid under pressure can have enough 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.
Refer to "Lubrication and maintenance chart" for quick reference to maintenance operations.
Caution :
Do not operate the backhoe if the fittings are leaking or if the hoses are damaged. A sudden
line burst could cause the boom, dipper stick or bucket to drop suddenly, causing damage
to the tractor or backhoe or injury to personnel.
Caution :
Operate the backhoe from the operator seat only.
Caution :
Do not stand or walk under a raised backhoe. Accidental movement of control lever or leak in
hydraulic system could cause boom or dipper stick to drop, causing severe injury.
Check the tractor hydraulic system as outlined in the Tractor operator's manual.
Note:
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.
Inspect hydraulic hoses, connections, control valve and cylinders for evidence of leakage.
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.
