and other material clear when pouring. Fill to
just beneath lower rim of hole. Replace oil ll

page 2.
Lubrication
• Add lubricating oil (WD-40) to all moving parts
when needed.
• For light duty use, lubricate every six months.
• For heavy and constant use, lubrication is
recommended every month.
MAINTENANCE
Rust Prevention:
• Check ram and pump plunger on the Power
Unit Assembly every two months (or sooner,
based on usage) for any signs of rust or
corrosion. Lift the jack as high as it goes
and look under and behind the lifting arm. If
signs of rust are visible clean as needed and
wipe down with with an oily cloth or cloth
sprayed with WD-40.
• When storing the jack, always have the
saddle and pump plunger in the down
postion.
ALWAYS USE A GOOD GRADE
HYDRAULIC JACK OIL. DO NOT USE
HYDRAULIC BRAKE FLUID, ALCOHOL,
GLYCERINE, DETERGENT, MOTOR
OIL OR DIRTY OIL. USE OF AN UN-
RECOMMENDED FLUID CAN CAUSE
DAMAGE TO YOUR JACK.
Air Purge Procedure
During shipment, air may get into the
hydraulic system causing reduced lifting
performance. Perform Air Purge Procedure
described on page 2.
• Continue to pump jack handle to lift vehicle to
desired height.
• After lifting, support the load with
appropriately rated vehicle support stands
before working on vehicle.
WARNING: Never work on, under, or around a
load supported only by a hydraulic jack.
Lowering the Jack
• Raise load high enough to clear jack stands;
then carefully remove the stands.
• Carefully open the release valve by slowly
turning the handle counterclockwise.
• After removing jack from under vehicle, if
saddle has not fully descended, push it all the
way down. This will reduce ram exposure to
rust and contamination.
