MAINTENANCE:
Important: Both the maintenance and repair of the jack may only be performed by qualiĮed persons, who have suĸcient
knowledge of the hydraulic system used in these jacks
Regularly lubricate the moving parts; wheels, arms, handle and pump roller pin.
Only original replacement parts should be used.
EXTREMELY IMPORTANT: NEVER use brake ŇƵŝd OR transmission Ňuid for lubricaƟon, or for Įůůing the
hydraulic system. Use ONLY quality hydraulic jack oil for lubricĂƟon and Įůling of the hydraulic system. We recommend Mobil
When the jack is not in use, make sure the liŌing arm is fully retracted to avoid corrosion.
Replace the hydraulic ŇƵŝd in the reservoir at least once a year. To check the hydraulic ŇƵŝd level, lower the ůŝŌŝŶŐ
arm completely.
The hydraulic ŇƵŝd level should be just below the Įller plug. If the oil is too low, the jack will not raise to its ƐƉĞĐŝĮĞĚ
maximum height. Replenish if necessary, and reinstall the rubber Įller plug. Do not overĮll the jack. Excessive
hydraulic oil may render the jack inoperaƟve.
Inspect the jack before each use. Take correcƟve ĂĐƟon or remove the jack from service if any of the following
problems are found:
A. Cracked or damaged frame
B. Leaking hydraulic ŇƵŝd
C. Scored, damaged piston rod
D. Loose hardware
E. ModiĮed equipment
Keep warning labels and instrucƟonal decals clean and readable. You may use a mild soap soluƟon to wash external surfaces
