HYDRAULIC HOSES AND FITTINGS

Hydraulic hoses are severely worked on a backhoe. Examine them daily and replace if necessary. Hose routing is very important. Make certain hoses can move freely, without kinking, and cannot be damaged or cut by backhoe action.

When tightening hoses and fittings, always use two wrenches: one to hold hose and one to tighten fitting. This will prevent hose from twisting and kinking.

Always back lock nut off and screw fitting all the way in for fitting that use O-rings￿￿￿￿￿￿￿for sealing. Then hold in position and tighten lock nut.

IMPORTANT

■ Fittings with O-rings and flange do not require additional sealant, replace damaged O-rings.

LUBRICATION

„Keep all persons away from operator control area while performing adjustments, service, or maintenance.

Do not let excess grease collect on or around parts, particularly when operating in sandy areas. Figure 13 shows lubrication points for the backhoe.

It is recommended that all fittings be lubricated daily or every eight hours of operation. In very wet or dry condi- tions, lubricate every four hours of operation. Use an SAE multi-purpose type grease for all locations shown unless otherwise specified. Be sure to clean fitting thor- oughly before using grease gun. One good pump of most guns is sufficient.

Position backhoe for easy lubrication by placing boom and dipper at 90° to each other with bucket cutting edge vertical and teeth resting on ground. Lower stabi- lizers to lubricate cylinders.
