Fill the oil reservoir with a recommended hydraulic fluid, as listed in the Maintenance portion of this manual. Connect the hydraulic hoses and fittings as illustrated in the parts manual supplied with the hoist and the pump. Use Loctite Hydraulic Sealant on all threaded NPT pipe joints.
12. Grease all hoist, tail hinge, and drive line grease fittings. This will prevent damage and insure smooth operation. When greasing the hoist, pump the grease until a generous amount comes out the ends. This ensures complete lubrication.
13. Following the procedures discussed in sections 14 and 15, depending on the hoist model. Raise the bed slowly in steps checking for clearance of all hoist and drive line components. Raising the hoist and stopping it in several positions to check for clearance will help prevent damage to the truck and hoist. Areas to check include: the pump, the PTO drive shaft, cylinder swing, top mounts, bed cross sills, tail hinge, etc. See the Operation portion of this manual for operation instructions that apply to your hoist.

14. Single Acting Cylinders: For single acting (power up only) cylinder hoists, complete the steps in this section. If the hoist is operated with no clearance problems then raise the hoist until fully extended. Support the bed with a suitable overhead hoist to prevent lowering of the truck bed. With the pumprunning, and the control knob in the raise position, loosen the bleeder screw (at the top of the cylinder) one half turn to allow the air to escape (see Figure 15).Do not remove the bleeder screw or the ball may be lost (see Figure 16).When the air and foam stops escaping from the bleeder screw, and the fluid isclear, retighten the bleeder screw. Unhook the overhead hoist and lower the truck bed.

15. Double Acting Cylinders: Forhoists designed as double acting (power up and power down) complete the stepsin this section. If the hoist is operating with no clearance problems, then raise the hoist to half of the possible dump angle. Support the bed with a suitable overhead hoist to prevent lowering of the truck bed. Fill the hydraulic tank 3/4full with hydraulic fluid. Continue to raise the hoist fully. Unhook the overhead hoist and lower the truck bed.
16. Raise and lower the hoist several times. Check the hydraulic fluid in thereservoir according to the pump installation instructions.
17. All installations must include a safety prop. To install a safety prop onthe truck, raise the unloaded body to the approximate desired height.
