If you need help with the Model H8093, call our

Technical Support line at: (570) 546-9663.

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.

Operation

To raise the jack, rotate the pump valve knob

clockwise completely, then move the pump han-

dle or foot pump up and down. To lower the jack,

slowly rotate the pump valve knob counterclock-

wise.

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 H8093 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 top cover plate from the jack and

remove the fill plug shown in Figure 2.

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 valve knob counterclock-

wise one full turn.

3. Pump the jack 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.
