a. Once a year.
b. After receiving a shock load. Take the jack out of service until the
technician certifies that it is safe to use.
WARNING! Only qualified service personnel should repair the tool. An
improperly repaired tool may present a hazard to the user and/or others.
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 jack 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.
REFILL THE HYDRAULIC JACK
The pump may become less efficient when the hydraulic oil level is too low or
contaminated by metal particulate through normal wear-and-tear.
1. Retract the ram and remove the oil filler plug.
2. Check and maintain the ram oil level.
• Check the oil level with the oil dip stick. Use a long plastic cable tie
as a substitute if the unit does not have a dipstick.
3. Fill the cylinder with a high quality hydraulic jack oil, up to the oil plug
opening.
a. Place a funnel into the oil fill neck. The funnel opening should be
wide enough to prevent the oil from collecting in the funnel' s cone.
