HOW IT WORKS
With Release Valve Closed
• An upward stroke of the jack handle draws oil from the reservoir tank into the plunger cavity.
Hydraulic pressure holds the valve closed, which keeps the oil in the plunger cavity.
• A downward stroke of the jack handle releases oil into the cylinder, which forces the ram out.
This raises the saddle.
• When the ram reaches maximum extension, oil is bypassed back into the reservoir to prevent an over
extended ram stroke and possible damage to the jack.
• Opening the release valve allows oil to flow back into the reservoir. This releases hydraulic pressure on the
ram, which results in lowering the saddle.
MAINTENANCE
TO ADD OIL
• Position the jack on level ground and lower the saddle.
• Use a flat blade screwdriver to pop off the inspection plate.
• Remove the oil plug.
• Fill the oil case until oil level is just beneath the lower rim of oil fill hole. Replace oil plug.
• Perform the Air Purge Procedure described below.
TO REPLACE OIL
• Fully open release valve by turning handle counterclockwise as far as it will go.
• Turn the jack over so that old oil will drain from the oil fill hole.
• Refill through oil fill hole. Keep dirt and other material clear when pouring. Fill to just beneath lower rim
of hole. Replace oil plug.
• Perform Air Purge Procedure described on page 6.
LUBRICATION
• Add lubricating oil to all moving parts when needed.
• For light duty use lubricate every six months.
• For heavy and constant use lubrication recommended every month.
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 an oily cloth.
• When storing the jack, always have the saddle and pump plunger in the down position.
WARNING! 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.
