Maintenance and Servicing
Procedures not specifically explained in this manual must be performed only by a qualified technician.
TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION: Do not use damaged equipment.
If abnormal noise or vibration occurs, have the problem corrected before further use.
Cleaning, Maintenance, and Lubrication
1.
BEFORE EACH USE,
inspect the general
condition of the Jack. Check for:
• broken, cracked, or bent parts
• loose or missing parts
• any other condition that may
affect its safe operation.
If a problem occurs, have the problem
corrected before further use.
Do not use damaged equipment.
2.
Before each use, thoroughly test the Jack
for proper operation prior to its actual use.
If the Jack appears
not
to be working properly,
follow
Bleeding
instructions on facing page.
3.
Change the hydraulic fluid at least
once every three years:
a. With the Jack fully lowered, remove the Fluid
Fill Plug on the side of the Ram housing.
b. With assistance, tip the Jack to allow the old
hydraulic fluid to drain out of the Ram housing
completely, and dispose of the old hydraulic
fluid in accordance with local regulations.
c. With the Jack upright, completely fill the
Ram housing with a high quality hydraulic
fluid (not included) until the fluid just
begins to run out of the Fluid Fill Hole.
d. Then reinstall the Fluid Fill Plug.
4. Clean with a clean cloth with a detergent
or mild solvent. Store the Jack in a safe,
dry location out of reach of children
.
Troubleshooting
TO PREVENT SERIOUS INJURY: Use caution when troubleshooting a malfunctioning jack.
Stay well clear of the supported load. Completely resolve all problems before use.
If the solutions presented in the Troubleshooting guide do not solve the problem, have a qualified technician
inspect and repair the jack before use.
After the jack is repaired: Test it carefully without a load by raising
it and lowering it fully, checking for proper operation, BEFORE RETURNING THE JACK TO OPERATION.
DO NOT USE A DAMAGED OR MALFUNCTIONING JACK!
