ENSURE THAT ALL PERSONNEL AND TOOLING ARE CLEAR BEFORE LOWERING
THE LOAD. DANGEROUS DYNAMIC SHOCK LOADS ARE CREATED BY QUICKLY
OPENING AND CLOSING THE RELEASE VALVE AS THE LOAD IS BEING LOWERED.
THE RESULTING OVERLOAD MAY CAUSE HYDRAULIC SYSTEM FAILURE, WHICH
COULD CAUSE SEVERE PERSONAL INJURY AND OR EQUIPMENT DAMAGE.
MAINTENANCE
IMPORTANT: Use only the recommended grade of hydraulic oil such as
Mobil DTE 13
.
Avoid mixing different types of fluid. NEVER use brake fluid, turbine oil, automatic
transmission fluid, motor oil or glycerine.
Improper fluid can cause premature failure of the jack and the potential for sudden and
immediate loss of load.
ADDING OIL
1. With the cylinder fully lowered and the pump piston fully closed, set the jack in its
upright position on a level surface. Remove the oil filler plug/screw.
2. Fill until the oil is level with the filler plug/screw hole; reinstall oil filler plug/screw
ensuring that all excess oil is thoroughly wiped clean from the jack body.
CHANGING OIL
For the best performance and prolonged service life,
replace the hydraulic oil at least
once a year
using the correct grade as noted under the heading
MAINTENANCE
.
1. With the cylinder fully closed and the pump piston fully closed, remove the filler
plug/screw.
2. Lay the jack onto its side and drain the fluid into a suitable container.
3.
NOTE:
All oils should be disposed of correctly and not poured into any drainage
systems. Check with your local authorities to ensure the correct procedure for
disposal
4. Fill with the correct grade of hydraulic oil (Mobil DTE 13 recommended) or a
suitable equivalent.
LUBRICATION
1. A coating of light lubricant oil should be applied to all pump pivot points ensuring
that all linkages operate freely.
2. Periodically check the pump piston and cylinder ram for signs of corrosion, pitting
and damage. Clean as needed and wipe with a lint free oily cloth.
3. NEVER USE ABRASIVE PAPERS OR OTHER ABRASIVE MATERIALS ON
THESE SURFACES.
4. Periodically remove the toe fabrication and apply a thin film of grease to the inner
face of the toe and the mating face on the cylinder support plate.
5. When not in use, store the jack with piston pump and cylinder fully closed.
