Note: Do not touch Handle when adding the hydraulic oil.
3. Replace the Fill Screw (Fig. 2).
Lifting
1. Park vehicle on a at, level, solid, surface safely
away from oncoming trafc. Turn off the vehicle’s
engine. Place the vehicle’s transmission in “PARK”
(if automatic) or in its lowest gear (if manual).
Set the vehicle’s emergency brake. Then,
chock the wheels that are not being lifted.
2. Turn the Release Screw (located under the
Handle Socket) counterclockwise to lower the
Jack. Once the Jack is fully lowered, turn the
Release Screw rmly clockwise to close it.
3. Carefully position Saddle of Jack (Fig. 1) under the
vehicle manufacturer’s recommended lifting point. If
equipped, the Elevating Screw can be used to alter the
height of the jack’s saddle; it is adjusted by turning the
saddle clockwise or counterclockwise. (See vehicle
manufacturer’s owner’s manual for location of frame
lifting point when lifting only one wheel, and frame lifting
points when lifting entire front or rear end of vehicle.)
4. Pump the Handle until the top of the Jack’s Saddle
has nearly reached the vehicle lifting point.
Note: The Jack should be positioned at 90° to the
vehicle’s lifting point to ensure the Jack’s Saddle
and vehicle lifting point are in alignment. If not,
reposition the Jack before lifting the vehicle.
5. To lift the vehicle, pump the Handle of the Jack.
Use smooth, full strokes for best results.
6. Once the vehicle is raised, slide a jack stand of
appropriate capacity (not included) under the
proper lifting point referred to in the vehicle owner’s
manual. Always use two jack stands, position them
at the same point on each side of the vehicle.
WARNING! The rated capacity of jack stands is per pair,
not the individual capacities combined unless specically
noted on the product by the jack stand manufacturer. Do
not exceed rated jack stand capacity. Ensure that the
vehicle support points are fully captured between the outer
lugs of both jack stands. Use a matched pair of jack stands
per vehicle to support one end only. Use 1 pair per vehicle
only. Failure to do so may result in sudden loss of load,
which may cause personal injury and/or property damage.
