INSPECTION

HYDRAULIC OIL

Check hydraulic oil sight gauge (Figure 10) to ensure that hydraulic oil is at the midway level.

Figure 10. Hydraulic Oil Sight Gauge

HYDRAULIC HOSES

Check hydraulic hoses to make sure they are not worn, frayed or defective.

GREASE FITTINGS (BEARINGS)

Check the zerk grease fittings (Figure 11) on the bearing housings and dump support brackets at each end of the mixing drum. These grease fittings lubricate the dumping mechanism. If the dumping handle is stiff or hard to move lubricate these fittings.

Figure 12. Grease Fittings (Dump Cylinder)

BLADE CHECK

Check for worn or paddle blades. Make sure that all blades are adjusted properly. See blade adjustment procedure in this manual. Replace all defective or damaged blades immediately.

1.Remove and retain nuts (2) and bolts (2) that secure dump handle to the drum in towing position.

2.Place dump handle in operating position and re-install nuts and bolts to secure dump handle to drum.
