Operating Instructions • Preventative Maintenance
SETUP
PlEASE REFER TO THE EXPlODED VIEW DRAWING IN THIS
MANUAl IN ORDER TO IDENTIFY PARTS.
1 . Place the hydraulic power unit in an upright position . Secure the legs
(index #2-4) to the cylinder (index #1-1) with the bolts (index #2-5),
washers (index #2-6) and nuts (index #1-29) . Do not tighten .
2 . Secure swivel casters (index #2-1 and #2-7) to leg caster brackets as
shown in the exploded view drawing on page 5 .
3 . Tighten the hardware that secures the legs (index #2-4) to the
cylinder (index #1-1) .
4 . Place the saddle assembly (index #3-31) on the stud protruding from
the top of the hydraulic unit assembly, (RS7796HUBK) . Align the
hole in the saddle with the hole in the stud and secure with the bolt
(index #3-26) and nut (#3-27) .
5 . Sometimes air gets trapped in the second stage hydraulic system
during shipping and/or handling . Evidence of an air bound system is
when a jack will not pump full incremental pump strokes .
TO PURGE AIR FROM THE HYDRAUlIC SYSTEM:
a . With the release valve knob (index #1-67) closed, turn the knob in
a counterclockwise direction two full rotations .
b . Pump the jack handle (index #1-79) fifteen times .
c . Close the release valve knob (index #1-67) by turning it
clockwise until it stops .
d . Pump the jack to maximum extension . If the condition seems
better, repeat steps "a" through "d" until air is purged
from the system .
6 . The primary stage of the power unit is air activated . The air
activated portion will also give the user many years of trouble free
operation if the shop air system is properly maintained . The shop air
system must have an air regulator adjusted to the proper pressure .
The system must be free from dirt and moisture . Do not drop
disconnected air lines on dirty shop floor or dirty environment and
then reconnect to the jack . Contaminants in the air system can cause
the air valve to malfunction and the air cylinder to score .
Contaminants and/or water found in the air cylinder voids the
warranty .
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 .
OPERATION:
1 . Lift the vehicle to the desired work height and support the vehicle in
accordance with the lift manufacturer's recommended support
procedure and all the instructions and warnings in this manual .
2 . Use an under hoist stand rated greater than the weight of the engine
to support the engine before unbolting the transmission
from the engine or bolting the transmission to the engine .
3 . Position the transmission jack directly under the transmission .
Depress the foot pedal marked "UP" to raise the jack to maximum
first stage height . Pump the handle on the hydraulic second stage in
order to raise the saddle to a height very close to the center of
balance point of the transmission oil pan but do not touch the
transmission .
4 . Adjust the ratchet arms on the saddle so that the bent up section of
the arms will fit in the mounting flange around the perimeter of the
transmission oil pan . Slowly and gently pump the jack so the
connection is made and then secure the transmission to the jack's
saddle with the tie down strap provided . Sometimes it is necessary
MTN2158 05/03/11
to turn the fore and aft and side to side tilt knobs so the saddle is in
the proper alignment with the transmission pan before securing the
load to the saddle .
5 . Make sure the tie down strap is very tight when securing the
transmission to the saddle and before raising or lowering the
transmission .
6 . Remove the transmission from the engine according to instructions
in the vehicle service manual .
7 . Once the transmission has been disconnected from the engine, very
slowly turn the release valve on the second stage hydraulic block in
a counterclockwise direction . Make sure the jack's saddle and
transmission do not hang up on any under car components, wiring,
fuel lines, etc . Continue to lower the load until the second stage
bottoms out and then depress the first stage "DOWN" pedal to
lower the transmission all the way down .
8. When installing a transmission, follow the above instructions but in
the applicable order and according to the vehicle manufacturer's
installation procedure .
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 . IMPORTANT: Any jack found
to be defective as a result of worn parts due to lack of
lubrication or air/hydraulic system contaminated with water,
rust and /or foreign materials from the air supply or other
outside source is not eligible for warranty consideration .
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 . Lubricate moving parts, excluding the telescopic rams, monthly with
a general purpose grease .
IMPORTANT: any jack found to be defective as a result of worn parts
due to insufficient or lack of lubrication is 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 qualified hydraulic repair personnel who are
familiar with this equipment .
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 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 . Do not attempt to make any hydraulic repairs unless you are a
qualified hydraulic repair person that is familiar with this equipment .
Repairs must be performed by an authorized service center .
