SETUP
PLEASE REFER TO THE EXPLODED VIEW DRAWING IN THIS
MANUAL IN ORDER TO IDENTIFY PARTS.
1 . In order to install the handle assembly item #54 in the handle socket
item #32, first align the main handle tube with the largest hole in
the handle socket and the lock pin rod with the smaller hole in the
handle socket .
2 . Make sure the lock pin rod is in the down/lock position before
insertion in the handle socket . Once the main handle tube and lock
pin rod are aligned with their respective holes in the handle socket,
push the handle assembly in the handle socket so the end of the
handle tube engages the release valve mechanism in the bottom of
the handle socket and the lock pin rod engages one of the three (3)
locking holes in the item #1 frame .
3 . Now rotate the "T" handle portion of the handle assembly so it is
perfectly aligned with the jack before tightening the item #36 bolt,
#35 washer and item #34 nut . Tighten the bolt, washer and nut so
the handle can not rotate . Disengage the lock pin rod by pulling
up on the lever and engaging the lever with the slot in top of the
handle assembly . The handle assembly should be free to pump up
and down .
4 . In order to check for proper handle assembly alignment with the
handle socket, see if the lock pin rod will engage with the three
locking holes in the frame . Also, turn the release valve knob at the
top of the handle assembly left and then right to see if the release
valve u-joint in front and below the handle socket is rotating
simultaneously with the turning of the knob .
5 . Before Use: Air may become trapped in the hydraulic system .
TO PURGE AIR FROM THE HYDRAULIC SYSTEM
a . Rotate the knob at the top of the handle assembly in a
clockwise direction until tight . Now turn it in a
counterclockwise direction two full turns .
b . Activate the foot pump pedal item #33 about 15 times .
c . Rotate the knob at the top of the handle assembly in a
clockwise direction until tight .
d . Activate the foot pump until the lift arm is raised to maximum
height . You should experience a full pump stroke with each
incremental pump of the pedal .
e . If it does not feel your are getting full incremental pump
stroke at anytime during the pumping operation, 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 . To raise load: Turn the knob at the top of the handle assembly in a
clockwise direction until tight . Position the jack under the load .
Proceed to pump the handle or the foot pedal 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 . Remember that foot pedal pump
operation is only used to quickly raise the saddle to the load . The
handle pump operation of the jack is used to lift the load . Raise the
load to the desired work height . Place jack stands of appropriate
Operating Instructions • Preventative Maintenance
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 REMOVING THE
JACK STANDS!
Once jack stands are positioned, turn the knob at
the top of the handle assembly 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 .
NOTE:
Once the hand pump operation has ceased, the
handle assembly can be locked in any of the three (3) handle locking
positions . Typically, the handle locking positions are used for moving
the jack around the shop, keeping the handle out of the way, or
preventing the handle from being pumped .
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 the knob at the top of the jack's handle assembly 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 wheels,
elevator arm, handle base pivot bolts, release mechanism and all
other bearing surfaces . Jacks found to be defective due to 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 AW150 .
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 .
