LIFT TRUCK REQUIREMENTS

PUSH PULL HYDRAULICS

Hydraulic fluid: petroleum based hydraulicfluid onlyHydraulic supply group: includes hoses andtake-up - one set for each function

Recommended truck pressure: 2000 to 2500PSI (135 to 170 bar)Oil volume: 7-10 GPM (26.5 to 38 l/min)

GENERAL INSTALLATION PROCEDURES

1. Platens require support of the truck forks. Forks need to be 1.5" to 2.0" (38mm to 50mm)thick X 4.0" to 6.0" (100mm to 152mm) wide and within 6.0" (152mm) of usable length. Donot exceed usable length. Align forks with attachment fork pockets; drive forward until forksare completely inserted into fork pockets. Lower mast, shut off truck and engage parkingbrake.

2. Engage attachment lower retainers.

3. Attach truck supply group (take-up) to hoses supplied on the attachment base.

4. Standing clear of the Push Pull attachment cycle the attachment in and out several times todistribute the hydraulic oil. Use caution because partially filled hydraulic lines may causeerratic movement.

CAPACITY

Capacity shown on the Push Pull name plateis for the Push Pull only. Load carryingcapacity of the attachment depends uponthe lift truck forks. Load weight plus attach-ment weight must never exceed the ratedcapacity of the forks. The combined truckand Push Pull capacity is provided by the lifttruck manufacturer.

GENERAL WEEKLY INSPECTION AND MAINTENANCE

1. Check all hydraulic fittings, hoses, cylinders and valves for leakage - repair or replace asrequired.

2. Check hoses for pinch points and signs of wear. Replace worn or damaged hoses.

3. All bolts should be checked and tightened as required.

4. Check all weld joints for signs of cracking - paying close attention to the linkage group weldsand all platen welds.

Auxiliary valves: 1 Function = a single auxiliaryvalve
