OWNER'S MANUAL
MODEL 6603B
CAPACITY: 3 TON
FLOOR SERVICE JACK
SETUP
PLEASE REFER TO THE EXPLODED VIEW DRAWING IN THIS MANUAL IN ORDER TO IDENTIFY PARTS.
1. Insert the upper handle #31 in the lower handle #30. Align the cross holes in both handles and secure them with the screw #29.
2. Remove the handle bolt #24 from the handle socket #22. Install the assembled handle into the handle socket #22 making sure the
bottom of the handle engages the gear shaft #28.
3. Install the handle bolt #24 in the handle socket #22 and tighten the bolt to secure the handle in the handle socket.
4. Air may become trapped in the hydraulic system during shipping and handling. Trapped air will affect the pumping performance of the
jack. If this occurs, follow the air purging procedure below:
a) With the lift arm #42 in its down position, turn the handle two full rotations in a counterclockwise direction.
b) Pump the jack approximately 15 full incremental pump strokes. Turn the handle in a clockwise direction until it stops.
c) Pump the lift arm to maximum height. If the pumping condition has improved, repeat steps "a" through "c" until all of the air has
been 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.
To raise load:
Turn the handle in a clockwise direction until tight. Position the jack under the load. Proceed to pump the handle in order
to raise the lift arm to the load. As the saddle at the end of the lift arm gets closer to the load, reposition the jack so the saddle will
contact the load firmly and the load is centered on the saddle. Make sure the saddle is correctly positioned. Raise the load to the desired
work height. Place jack stands of appropriate capacity at the vehicle manufacturers's recommended support areas that provide stable
support for the raised vehicle.
DO NOT CRAWL UNDER VEHICLE WHILE LIFTING VEHICLE OR PLACING OR REMOVING THE
JACK STANDS!
Once jack stands are positioned, turn the handle counterclockwise VERY SLOWLY. Lower the load to rest on the jack
stands. Inspect the relationship between the jack stands and load to make sure the setup is stable and safe. If the setup is not stable or
safe, follow the preceding steps until corrected.
2.
To lower load:
Follow the procedures mentioned in "To raise load" section of the OPERATING INSTRUCTIONS in order to raise the load
off the jack stands. Once the load has cleared the jack stands, remove the stands from under the load and away from the work area. Turn
handle very slowly in a counterclockwise direction until the load is completely lowered to the ground. Once the jack's lifting saddle has
cleared the load, remove the jack from under the load. CAUTION: Keep hands and feet away from the hinge mechanism of the jack.
PREVENTATIVE MAINTENANCE
This is the safety alert symbol used for the PREVENTATIVE MAINTENANCE section of this manual to alert you to potential personal
injury hazards. Obey all instructions to avoid possible injury or death.
1. Always store the jack in a well protected area where it will not be exposed to inclement weather, corrosive vapors, abrasive dust, or any
other harmful elements. The jack must be cleaned of water, snow, sand or grit before using.
2. The jack must be lubricated periodically in order to prevent premature wearing of parts. A general purpose grease must be applied to all
zerk grease fittings, caster wheels, front axle, lift arm, handle base pivot bolts, release mechanism and all other bearing surfaces.
Worn parts resulting from inadequate or no lubrication are not eligible for warranty consideration.
3. It should not be necessary to refill or top off the reservoir with hydraulic fluid unless there is an external leak. An external leak requires
immediate repair which must be performed in a dirt-free environment by an authorized service center.
IMPORTANT:
In order to prevent seal damage and jack failure, never use alcohol, hydraulic brake fluid or transmission oil in the jack.
Use Chevron Hydraulic Oil AW ISO 32 or its equivalent Unocal Unax AW 150.
4. Every jack owner is responsible for keeping the jack labels clean and readable. Use a mild soap solution to wash external surfaces of the
jack but not any moving hydraulic components.
5. Inspect the jack before each use. Do not use the jack if any component is cracked, broken, bent, shows sign of damage or leaks
hydraulic fluid. Do not use the jack if it has loose or missing hardware or components, or is modified in any way. Take corrective
action before using the jack again.
6. Any hydraulic repairs within the warranty period must be performed by an authorized service center.
