– Check the thrust plate and the pump piston on the drive unit assembly
every two months (or more often, depending on usage) for signs of rust
spots or corrosion. extend the floor jack as far as possible and also
check the points under and behind the lifting arm. If signs of rust are
visible, clean the corresponding areas and rub them with an oily cloth or
lubricating oil.
– Always store the floor jack with plate and pump piston in the lowered
position.
ALWAYS USE A HIGH QUALITY HYDRAULIC OIL FOR FLOOR JACKS.
DO NOT USE ANY HYDRAULIC BRAKE FLUID, ALCOHOL, GYLCERINE,
CLEANING AGENTS, ENGINE OIL OR USED OIL. USING OILS NOT
RECOMMENDED CAN LEAD TO DAMAGE TO YOUR FLOOR JACK.
During delivery or after topping up with oil, air can get into the hydraulic
system and lead to poor lifting performance on the appliance. In such a
case it is necessary to bleed the air as follows:
1. Fully turn the release valve anti-clockwise to completely open the
release valve.
2. Pump with the handle several times with quick movements.
3. turn the release valve clockwise to close the release valve.
4. Pump with the handle until the lifting arm reaches its maximum extension
length and continue with the pumping movements to allow air trapped in
the thrust plate to escape.
5. Fully turn the release valve anti-clockwise to lower the lifting arm to its
lowest position. If necessary exert force on the plate.
6. turn the release valve clockwise to close the release valve and check
the pump action is working properly. It may be necessary to repeat the
above steps several times to ensure that all the air can escape from the
system.
