Technical Support line at: [phone].
Failure to follow these instructions could
result in serious personal injury or death:
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 appro-
priately rated support stands before
working under it.
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.

Pump
Handle
Operation
Pump Handle (Figure 1): To raise the jack, rotate
the pump handle clockwise completely, then move
the pump handle up and down. To lower the jack,
slowly rotate the pump handle counterclockwise.

Maintenance
Keep the hydraulic rams clean and free of any
dust, dirt, or foreign debris. Abrasive material
stuck to the ram can damage the hydraulic seal
when the ram is retracted back into the jack.
Regularly wipe the hydraulic rams clean with a
lightly oiled rag.
The Model H8094 will require hydraulic fluid after
long-term use. This will be noticeable if the jack
will not reach its maximum height when pumped.
Only use a high quality hydraulic fluid.
To add hydraulic fluid:
1. Completely lower the jack.
2. Remove the fill plug shown in Figure 2.
Figure 2. Fill plug.
Bleeding the Air
If the jack becomes spongy or will not rise when
pumped, then air bubbles may be in the hydraulic
system.
To remove the air bubbles:
1. Remove the fill plug.
2. Rotate the pump handle counterclockwise
one full turn.
3. Pump the handle quickly ten times to purge
the air from the system.
4. Replace the fill plug and test the operation of
the jack.
—If the jack did not perform properly, then air
may need to be bled from the pump system
again.
3. Add fluid until it reaches the top of the fill plug
hole.
4. Replace the fill plug.
5. Test the operation of the jack by pumping
it up to the maximum height and applying a
load. The jack should hold the weight of the
load without a sinking or spongy feeling.
—If the jack did not perform properly, then
air may need to be bled from the pump
system.
