REPLACING OIL
For best performance and longest service life, replace the entire oil supply at least once per year.
ALWAYS use a good grade hydraulic jack oil. Do not use hydraulic brake fluid, alcohol, glycerin,
detergent, motor oil or dirty oil. Use of an unrecommended fluid can cause damage to your jack.
(USE ISO VG 15 )
1. Prepare a suitable canister to contain the old oil.
2. Fully open the release valve by turning the handle (4) counterclockwise as far as possible.
3. Use a flat screwdriver to unscrew and remove the oil fill plug.
4. Turn the jack over so that the oil can drain from the oil fill hole into the canister.
5. Refill oil until the oil level is just beneath the lower rim of the oil fill hole.
6. Screw the oil fill plug (9) back to its original position.
7. Perform the air purge procedure as described below (Releasing trapped air).
LUBRICATION
1. Add lubricating oil to all moving parts when needed.
2. For light-duty use, we recommend lubricating every 6 months.
3. For heavy and constant use, we recommend lubricating every month.
RELEASING TRAPPED AIR
During shipment or after refilling the oil, air may become trapped in the hydraulic system, causing
poor lifting performance. The air has to be removed before starting operations of the service jack.
1. Remove the tool tray. Loosen the oil fill plug for about 3 full turns.
2. Using the handle (4), turn the release valve counterclockwise one full turn to open.
3. Pump the handle (4) rapidly for six to seven full strokes.
4. Tighten the oil fill plug. Turn the handle (4) clockwise to close the release valve.
5. Pump the handle (4) until the jack saddle (6) reaches its maximum height.
6. Turn the handle (4) counterclockwise one full turn and lower the saddle (6) to the lowest position. Use
force if necessary.
7. Turn the handle (4) clockwise to the closed position and check for proper pump action. It may be
necessary to perform the above procedure more than once to ensure that the air is completely evacuated.
