CAUTION:
Hydraulic fluid is an extreme slip hazard on any flooring surface.
Hydraulic fluid can be a skin irritant in rare instances and should be washed off
with soap and water.
If hydraulic fluid is exposed to the eye, flush immediately and continuously for 15
minutes.
1.
Place the CooLift on a level flooring surface with the holding brake engaged.
2. Elevate lift platform to maximum height with electric pump.
3. Remove deck screws from top of cylinders; set aside for reuse.
4. Block the lift platform with two 2” x 4” wooden spacer blocks on edge.
5. Lower the cylinders completely using the electric pump.
6.
Turn off the power switch.
7. Remove the bottom front and rear pans.
8.
Loosen the hydraulic fittings from each hydraulic cylinder using the 11/16” wrench. Use
absorbing material to capture escaping hydraulic fluid.
9. Remove the screws from the bottom of the CooLift which hold the cylinders in place (set aside
for reuse). Set old cylinder aside sitting upright with the fitting at the top as to not spill
hydraulic fluid (fluid will be reused).
10.
Position new cylinder in CooLift and finger tighten the flare fitting to the hydraulic fitting in the
new cylinder.
11. Replace the screws which secure the cylinders in the CooLift and tighten.
12.

14.
Pour hydraulic fluid from old cylinders into the pump reservoir.
15. Turn on the power switch.
