MAINTENANCE AND LUBRICATION

Jerr-Dan rollback truck decks are designed for years of service with little

maintenance. This small amount of maintenance, however, is very impor-

tant for durability and for safe operation of the deck.

Maintenance is an owner/user responsibility as neither the manufacturer

nor the distributor can normally control this function.

Use only safe practices when maintaining this equipment. Never get under

a tilted deck unless it is adequately supported (don’t rely on the hydraulic

system). Always shut off the engine before reaching into pinch areas as

when checking the hydraulic oil level or greasing under the deck. Maintain

a clean shop for safety. Clean up spilled oil immediately.

Inspect the vehicle and deck system periodically for damage or evidence

of pending failure. Damaged or broken parts should be replaced immedi-

ately. Never operate a machine which is known to be defective or operat-

ing improperly. The cause of any binding or leakage should be determined

immediately and the problem promptly fixed.

Sliding surfaces of deck beams are to be cleaned and coated with engine

oil periodically. Cleaning every six (6) months is recommended for normal

highway operations, but this frequency will vary appreciably with the type

of service. Sliding on dirty wear surfaces will cause rapid wear. Fittings on

linkage pivots should be greased every two (2) months, again depending

upon usage. See Lube Chart.

Check the hydraulic oil level bimonthly or after any leakage. Use 5W20

Dual Range hydraulic oil. (Automatic transmission fluid may be used in the

hydraulic system if necessary.)

The proper oil level is best checked by rolling the deck back enough to gain

access to the fill plug (unless the chassis configuration caused the oil tank

to be mounted abnormally far to the rear). The oil tank should be about

2/3 full with the deck so positioned (shut off the engine after moving the

deck). This will result in a 3/4 full tank with the cylinders fully retracted

(deck fully forward). (Proper oil level is achieved when the hydraulic oil is

within 1/2 inch of top of sight tube.)
