BOTTLE JACK SETUP INSTRUCTIONS
This is the safety alert symbol used for the SETUP INSTRUCTIONS section of this manual to alert you to potential personal injury
hazards . Obey all instructions to avoid possible injury or death .
SETUP
1 . Refer to the exploded view parts drawing in this manual to identify parts mentioned in this setup procedure .
2 . The three piece handle can be slip fit together to form a complete handle length . Loosely slipping the pieces together will enable you to
disconnect them at a later time for storage .
3 . Sometimes air gets trapped in the hydraulic system during shipping and/or handling .
PURGING AIR FROM THE HYDRAULIC SYSTEM
a . Attach the end of the handle to the jack's release valve and turn the handle in a counterclockwise direction two full revolutions .
b . Install the handle in the pump handle receiver and pump the jack about 15 incremental pump strokes .
c . Attach the end of the handle on the release valve again and turn the handle in a clockwise direction until tight .
d . Proceed to pump the handle until the ram raises to maximum height .
e . Repeat steps "a" through "d" until all air is purged from the system .
OPERATING INSTRUCTIONS
This is the safety alert symbol used for the OPERATING INSTRUCTIONS section of this manual to alert you to potential
personal injury hazards . Obey all instructions to avoid possible injury or death .
IMPORTANT:
Before attempting to raise any vehicle, check vehicle service manual for recommended lifting surfaces .
OPERATION
1 . Become familiar with the identification and function of the operating jack components .
a . The ram is the shaft that comes out of the jack when you activate the pump piston .
b . The ram is equipped with an extension screw which can be unscrewed to extend from the ram if there is not enough hydraulic stroke
to raise the load to the desired height .
2 . Chock the vehicle's tires that will not be lifted off the ground prior to lifting the vehicle and if available, apply the emergency brake or any
other method of braking .
3 . Position the jack at the designated lift point . Estimate the required ram travel to raise the vehicle to the desired height . If the total ram
travel will not lift the vehicle to the desired height, unscrew the extension screw first so the low height of the jack will be higher, thereby
providing more effective ram stroke .
4 . Turn the release valve in a clockwise direction until tight .
5 . With the jack in the lowered position, place the jack under the vehicle, but do not put your body under the vehicle .
IMPORTANT:
Use the
vehicle manufacturer's recommended lifting procedures and lifting points before lifting loads .
6 . Once the jack is in place, activate the pump until the top of the ram comes close to the designated lift point . Make sure the designated
lift point is flat, parallel to the ground and free from grease, any kind of lubricant, and debris . Proceed with pumping the jack in order to
lift the vehicle to the desired height . During lifting, inspect the position of the jack in relation to the ground and the ram in relationship to
the load to prevent any unstable conditions from developing . If conditions look like they are becoming unstable, slowly lower the load and
make appropriate setup corrections after the load is fully lowered .
7 . When the vehicle or load is lifted to its desired height, immediately place safety support stands (jack stands) in their designated
locations and adjust the stands' support columns up as close to the designated vehicle support points as possible . Although jack
stands are individually rated, they are to be used in a matched pair to support one end of the vehicle only . Stands are not to be used to
simultaneously support both ends or one side of a vehicle . Slowly and carefully turn the release knob in a counterclockwise direction to
gently lower the vehicle onto the safety support stands (jack stands) . Make sure the vehicle is safely supported by the safety support
stands' (jack stands) saddles and not the locating lugs of the saddles . Inspect the relationship of the safety support stands (jack stands)
with the ground and the safety support stand (jack stand) columns and saddles with the vehicle to prevent any unstable conditions . If
conditions look unstable, close the jack's release valve and pump the jack to raise the vehicle off the safety support stands (jack stands) .
Make the appropriate setup changes, and slowly and carefully lower the vehicle onto the safety support stand saddles .
8 . After the work is done, close the release valve and pump the jack until it is high enough to remove the vehicle or load from the safety
support stand saddles . Be sure load is stable . If it is not, lower load back onto safety support stands . Make appropriate setup corrections
and repeat the step again . Remove the safety support stands from under the vehicle, being very careful not to move the vehicle .
9 . Turn the release valve in a counterclockwise direction very slowly and carefully to lower the vehicle or load down to the ground .
