• Only original replacement parts should be used.
Extremely Important: never use brake fluid.
• When the jack is not in use, make sure the lifting arm is fully retracted to avoid
corrosion.
• Keep the jack in a clean, dry place and out of children’s reach.
• Replace the hydraulic fluid in the reservoir at least once a year. To check the
hydraulic fluid level, lower the lifting arm completely.
• The hydraulic fluid level should be just below the filler plug. Replenish if necessary,
and reinstall the rubber filler plug. Excessive hydraulic oil may render the jack
inoperative.

service if any of the following problems are found:
a. Cracked or damaged frame d. Loose hardware

• Keep warning labels and instructional decals clean and readable. You may use a
mild soap solution to wash external surfaces of the jack.
