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.
Check and maintain the ram oil level.
4.
Always store the hydraulic ram in the fully retracted position. This will help
protect critical areas from corrosion.
5.
Do not use brake or transmission fluids or regular motor oil as they can
damage the seals. Always purchase and use products labeled hydraulic
jack oil.
6.
Remove any hydraulic pump from service that is damaged, worn down or
operates abnormally, until repaired by an authorized service technician.
CHECK AND ADD HYDRAULIC OIL
1.
Fully retract the ram by turning the handle counterclockwise to open the
release valve.
2.
Loosen, but do not remove, the retaining screws (#25 and 26) holding the
panel (#35) on the body frame (#8). Lift the panel vertically to reveal the
pump's reservoir (#P14) and set the panel aside (Fig. 1 to 3).
3.
Remove the oil filler plug (#P16). The oil level must be within 1/2 in.
(13 mm) from the top of the reservoir.
4.
Add hydraulic oil to the reservoir.
