Jack Handle
Failure to follow these instructions could
result in serious personal injury or death:
To raise the saddle with the jack handle:
Turn the 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).
To raise the saddle with the foot pedal:
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 two inches.
To lower the saddle:
Slowly turn the jack handle counterclockwise.

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.
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.

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 H8092 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 3.
Figure 3. Fill plug.
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 to the saddle. 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.
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. These air bubbles must be 'bled' from
the hydraulic fluid before the jack can be safely
operated.
To remove the air bubbles:
1. Remove the fill plug.
2. Rotate the handle counterclockwise until it
stops.
3. Pump the jack handle rapidly to force the air
bubbles out through the fill hole. When the air
bubbles and fluid stop coming out, put the fill
plug back.
4. Repeat Step 3 as many times as needed until
the air bubbles stop coming out in the hydrau-
lic fluid.
