FHM BACKHOE BH 8, Operation And Parts Manual

Page: 23 / 43

Farmer-Helper BH 8 & 9 23 Revision 08 - 2017
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.
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.
CAUTION
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.
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, dipperstick or bucket to drop suddenly, causing damage to the
tractor or backhoe or injury to personnel.
Operate the backhoe from the operator seat only.
Do not stand or walk under a raised backhoe. Accidental movement of control lever or leak in
hydraulic system could cause boom or dipperstick to drop, causing severe injury.
