PREVENTATIVE MAINTENANCE
This is the safety alert symbol used for the PREVENTATIVE MAINTENANCE section of this manual to alert you to
potential personal injury hazards. Obey all instructions to avoid possible injury or death.
1. Always store the kit in a well protected area where it will not be exposed to inclement weather, corrosive vapors, abrasive dust,
or any other harmful elements. The kit must be cleaned of water, snow, sand or grit before using.
2. Based on continuous engagement and disengagement of the hose from the cylinder, eventually it will become necessary to add hydrau-
lic fluid to the pump’s reservoir. Completely retract the ram before adding hydraulic fluid. Do not overfill in order to avoid personal injury
and hydraulic malfunction. Use only hydraulic jack oil,
Chevron Hydraulic Oil AW ISO 32 or its equivalent Unocal Unax AW 150
. Other
fluids will cause damage to the hydraulic seals.
IMPORTANT:
In order to prevent seal damage and kit failure, never use alcohol, hydraulic brake fluid or transmission oil in the pump.
3. Every kit owner is responsible for keeping the kit labels clean and readable. Use a mild soap solution to wash external surfaces
of the kit components but not any moving hydraulic components.
4. Do not attempt to make any hydraulic repairs unless you are a qualified hydraulic repair person that is familiar with this equipment.
Repairs must be performed by an authorized service center.
