HYDRAULIC RAM MAINTENANCE
Monthly maintenance is recommended for the hydraulic ram. Any restrictions
due to dirt, rust, etc. can cause the either slow movement or extremely rapid
jerks, damaging the internal components. The following steps are designed to
keep the pump maintained and operational.
1.
Lubricate the cylinder and the pumping mechanism with light oil.
2.
Visually inspect for cracked welds, bent, loose, missing parts or hydraulic
oil leaks.
3.
Inspect the hydraulic ram immediately if it was subjected to an abnormal
load or shock load.
4.
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 the hydraulic ram in the fully retracted position. This will
help protect critical areas from corrosion.
7.
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.
Lower the lift as low as possible with the pressure release pedal (L).
2.
Remove the oil filler screw 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.
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.
LUBRICATION
Inspect and lubricate the tool when required. Only use light oil to lubricate
the tool. Other lubricants may not be suitable and could damage the tool or
cause a malfunction during use.
