Figure 1. Model H8091 Identification.
1. DO NOT overload this jack beyond its
rated capacity. Overloading can cause
the jack to collapse and drop the load.
2. ALWAYS support the vehicle with
appropriately rated support stands
before working under it.
Operation
To raise the saddle gradually:
Turn the jack handle clockwise as far as it will
turn and pump the handle up and down. Turning
the handle clockwise will close the release valve
(see Figure 2).
3. DO NOT attempt to move the vehicle
while the jack is in use.
4. Use only on hard level surfaces like
concrete or asphalt. Other surfaces are
potentially unstable.
5. Center the load on the jack to maintain
proper balance and stability.
6. DO NOT use jack if it begins leaking
fluid or if it sinks when placed under
load. These are indications that the jack
needs to be immediately serviced.
To raise the saddle quickly:
With the jack handle turned fully clockwise, push
the foot pedal down and release it slowly. Each
pump of the pedal will raise the saddle approxi-
mately one-third of its full range.
To lower the saddle:
Slowly turn the jack handle counterclockwise.
