Operation
Lowering Vehicles
.
1. First, clear any tools or equipment from under the vehicle. Make sure there are no
obstructions and that people are at a safe distance from the vehicle.
2. Position the Jack so that the Saddle (7.1) is at one of the recommended lifting points.
Pull back on the Screw Rod (1.4) and turn it to the right (see label on handle) to lock
the release valve. Pump the Handle (1.5) until the Saddle (7.1) fully engages the lifting
point, then continue to pump the Jack to the needed height above and clear of the jack
stands.
3. Remove the jack stands.
Note:
Position yourself safely so that you are not under any
part of the vehicle before lowering the Jack or removing the jack stands.
4. Slowly turn the Screw Rod (1.4) to the left and move the Handle (1.5) back and forth
until the Screw Rod drops as far as it will go. Now, turn the Screw Rod (1.4) right to
open the release valve and lower the vehicle.
5. Pull the Jack clear of the vehicle and store in a safe place.
Raising the Vehicle.
1. Position the Jack so that the Saddle (7.1) is at one of the recommended lifting points.
Pull back on the Screw Rod (1.4) and turn it to the right (see label on handle) to lock
the release valve. Pump the Handle (1.5) or the Foot Pedal (2.1) until the Saddle (7.1)
fully engages the lifting point, then continue to pump the Jack to the needed height.
2. Use jack stands (not included) that are capable of supporting the weight of the vehicle
being lifted. Use your vehicle’s owner’s manual to determine the specified points on
the vehicle to safely position jack stands.
3. Once the vehicle is safely positioned over the jack stands, slowly turn the Screw Rod
(1.4) to the left and move the Handle (1.5) back and forth until the Screw Rod drops
as far as it will go. Turn the Screw Rod (1.4) right to open the release valve and lower
the vehicle onto the jack stands. Caution: Press lightly on the Screw Rod until you are
able to judge the rate at which the vehicle is being lowered.
4. To determine if the vehicle is safely up on jack stands, stand away and attempt to gen-
tly rock the vehicle. Caution: Be prepared for the vehicle to suddenly drop if the jack
stands are not properly placed. If it sways and seems unstable, repeat the procedure
and reposition the jack stands. Test again.
General Maintenance
1. Keep the Jack clean and dry.
2. Periodically lubricate the bearing and axles on the caster wheels with high quality
grease. Use a grease gun (not included) to service the Jack’s zerk fittings.
3. Have a qualified service technician periodically dismantle and lubricate the handle
assembly and all lift arm linkages.
4. Watch for hydraulic oil leaks. Fill oil if necessary. If leaks persist, contact an authorized
service technician. Never use the Jack if it is leaking hydraulic oil.
5. If the Jack does not lift to satisfaction, it may have air in the hydraulic system and need
to be bled.
Note:
Bleeding and oil fill instructions follow on page 6.
