MAINTENANCE

GENERAL MAINTENANCE

GENERAL INFORMATION

Regular maintenance is the key to long equipment life and safe opera-

tion. Maintenance requirements have been reduced to an absolute mini-

mum. 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) thor-

oughly. 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

locations, 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 trans-

port 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 will 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 inspections and

help avoid overlooking worn or damaged components.
