Failure to follow these instructions could  
result in serious personal injury or death:  
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.
