Maintenance and Inspection
8.3
Maintenance instructions
m WARNING - All inspection and maintenance procedures
must be performed after the jack has been removed from
service. Failure to do this may result in personal injury and/or
property damage.
All warning and capacity labels should be readable and
complete. Wash external surfaces of jack, labels, and
decals with a mild soap solution.
Lubricate all rotating and sliding portions of the jack
monthly.
8.4
Adding hydraulic fluid
m WARNING - The oil reservoir in this equipment is
sealed and pressurized when in use. When checking
the fluid level, do not have the jack connected to the air
supply. Failure to heed this warning may result in
personal injury and/or property damage.
1. Remove the jack from service.
2. Disconnect the air line.
3. The ram must be in the fully-lowered position and the
jack must be on a level surface.
4. Carefully remove the plastic cover from the oil reservoir
plug located on the top surface of the jack body.
5. Clean around the surface of the oil fill plug to prevent
contamination of the hydraulic oil system.
6. Remove the oil fill plug using a 3/16 Hex wrench.
7. Visually check the hydraulic oil level. RAM MUST BE
FULLY RETRACTED. The oil should be within 1/4 inch
of the bottom of the oil fill hole. If the fluid level is low,
add a high-grade hydraulic fluid equivalent to Phillips 66
Megaflow™ AW HVI Hydraulic Oil 22.
m CAUTION - Do not use brake or transmission fluid. Use
of the wrong fluid can deteriorate the seals and
corrosion problems will occur.
8. Reinstall and secure the oil reservoir plug, replace the
plastic cover, and connect to air supply and test for
normal operation.
9. Troubleshooting
This section is a list of potential problems and solutions. If
the solution listed fails to correct the problem, call the
manufacturer at the numbers and address printed on the

and serial number of your jack available. The serial
number is permanently stamped on a metal tag attached
to the top of the frame.
