GENERAL MAINTENANCE

GENERAL INFORMATION

Regular maintenance is the key to long equipment life and safe operation.

Maintenance requirements have been reduced to an absolute minimum. However,
it is very important that these maintenance functions be performed as described
below.
EVERY 8 HOURS OF OPERATION

Grease all swivel points (ram and base end of all cylinders) thoroughly.

Excessive wear and even mechanical damage to pins and cylinders can result from
inadequate lubrication. Use a multi-purpose grease.

Lubricate all grease fittings with a multi-purpose grease. For grease loca-

tions, refer to the lubrication chart in Section H.
EVERY 40 HOURS OF OPERATION

Check hydraulic reservoir fluid level. If oil is low, check all lines, fittings, and

control valve for signs of leakage.
IMPORTANT: Hydraulic fluid level should be checked with backhoe in transport
position.

WARNING! Escaping hydraulic/diesel fluid under pressure can penetrate

the skin causing serious injury.

DO NOT use your hand to check for leaks. Use a piece of
cardboard or paper to search for leaks.
Stop engine and relieve pressure before connecting or discon-
necting lines.
Tighten all connections before starting engine or pressurizing
lines.
If any hydraulic/diesel fluid is injected into the skin, obtain
medical attention immediately or gangrene or other serious
injury may result.

Physically check all pins, bushings, cotter pins, nuts, etc., for signs of wear or

loose fit. Tighten as required, replacing where necessary. (Bolts and pins may
vibrate loose during operation.) Clean equipment of all dirt, oil, and excess grease.
This will assist you in making visual inspection and help avoid overlooking worn or
damaged components.
