4930A & 4950B PARTS LIST AND BREAKDOWN
OWNER'S MANUAL
SETUP INSTRUCTIONS
This is the safety alert symbol used for the ASSEMBLY section of this manual to alert you to
potential personal injury hazards. Obey all instructions to avoid possible injury or death.
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.
1.
Become familiar with the identification and function of the operating jack components. The ram is the shaft that comes out of the
jack when you activate the pump piston.
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.
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.
