1.
Fill the hydraulic tank with hydraulic oil (see oil specification in Maintenance Section.)
2.
Prime the pump by loosening the clamp on the suction hose at the pump. Pull the hose
back off the fitting till the air is bled from the line. Push the hose back on the fitting and
retighten the clamp.
3.
Engage the P.T.O. and run the pump at idle (700 to 900 RPM). Operate the cylinders at
full stroke five to ten times to bleed the air from the lines and cylinders. The cylinders
were filled with oil during testing at the factory, but some seepage may have occurred
during shipping and installation. Refill the hydraulic tank, if needed, during this
sequence and do not let the pump run without oil.
4.
Check for leaks and tighten fittings as necessary.
5.
Verify the movement of the control levers corresponds to the movement of the cylinders
per the figure below.
6.
Install all safety decals and product decals per Drawing No. 42H07 after final installation
and painting have been completed. The factory prior to shipment of a hoist, will install
some decals that have a premask layer. The premask will need to be removed after
painting the hoist. It is very important when removing the premask not to pull the
premask out and away from the decal at a 90° angle, but instead pull the premask straight
down at a 180° angle to the decal surface. Should problems occur with the premask
pulling the decal loose, wet the tack side of the premask with water via a spray bottle to
weaken the adhesive bond, while pulling straight down on the premask.
