Remove any hydraulic pump from service that is damaged, worn down
or operates abnormally, until repaired by an authorized service
technician.
5.
Check and maintain the ram oil level.
6.
Always store your crane with the hydraulic ram in the fully retracted
position. This will help protect critical areas from corrosion.

Do not use brake or transmission fluids or regular motor oil as they
can damage the seals. Always purchase and use products labeled
Hydraulic Oil.
BLEEDING THE HYDRAULIC SYSTEM
Bleed excess air from the hydraulic system as follows:
1.
Open the release valve (#36) by turning it counterclockwise.
2.
Remove the oil filler screw (#35) and fill the pump with hydraulic fluid.
3.
Wait 5 minutes for trapped air to rise to the surface.
4.
Pump the handle or pedal for several full strokes to eliminate any air in
the system.
5.
Check the oil filler hole and if necessary, top off with more
hydraulic oil.
6.
Restore the oil filler screw. Close the release valve by turning
clockwise.
7.
Test the ram several times for proper operation before putting it into
use. Do not use the ram if it still does not appear to be working
properly. Have a qualified service technician service or repair the
hydraulic system.
FOLDING THE LEGS
