HYDRAULIC FLOOR JACK 2T 85mm
INSTRUCTIONS
Before use:
1. Check Oil Level:
With the jack in an upright position and the ram completely retracted, open
release valve by turning release assembly counterclockwise. Please see illustration «C». Fill if
necessary with good grade hydraulic jack oil (SAE 10). Do not use brake fluid or motor oil.
2. Lubricate Internal Component:
With release valve open, pump the handle several strokes to
assure proper internal lubrication.
3. Bleed Hydraulic System:
During transportation, hydraulic jacks may become «airbound» causing
spongy ram action.
To bleed the hydraulic system:
• Close the release valve by turning the jack handle clockwise.
• Insert handle in sleeve and pump jack up to full height.
To release air from the hydraulic system:
• Open the release valve by turning the jack handle counterclockwise.
• Remove the oil filler plug from the cylinder.
• Rapidly pump jack handle through several full strokes
• Replace the oil filler plug into the cylinder again and jack is ready to use.
USE
1. Lifting
If raising a vehicle, be sure to set parking brakes and block the wheels first (please see illustration
«D»). Turn release knob clockwise to close release valve (please see illustration «E»). Position jack
under desired vehicle lifting point suggested by manufacturer (solid ground where free from oil
or slippery material). Be sure that load is centered and follow the listed steps to raise the saddle
rapidly to the chassis level.
• Insert attached handle in socket and pump handle until load is at desired height (for ease of
operation, lifting effort can be shared by additional persons).
