SETUP
1. Refer to the exploded view parts drawing for identification,
location and position of parts.
2. Install the swivel caster wheels on the jack legs with the
washers and nuts provided.
3. Find a hard floor thaI is flat. Install the legs on the Jack's base
with the allen socket cap screws and washers provided. Do not
tighten the allen socket cap screws until all four caster wheels are
touching the floor and the jack appears vertical.
4. Back the hex head screw oul at the saddle assembly ram
receiver so the saddle assembly will slip onto the ram. Once
mounted, tighten the hex head screw.
5. The chains and corresponding chain hardware are provided in
order to secure the transmission to the saddle assembly and
containing angles. One end of each chain should be anchored to
a containing angle. The restraint system (chain, chain hardware,
and containing angles) may be adjusted according to the specific
transmission configuration.
6, The jack is equipped with two reservoir fill plugs. Replace the
shipping fill plug with the vented fill plug belore operating the
jack.
7. Sometimes air gets trapped in the jack during shipment. An air
bound hydraulic system feels spongy when pumped and
sometimes the jack will not pump full incremental strokes.
PURGING AIR FROM THE HYDRAULIC SYSTEM
a. Open the release valve by depressing the "down" foot
pedal. With the "down' foot pedal depressed.
simultaneously activate the larger pump pedal about 15
times. It may be necessary to have one person depress
the "down" pedal while another person activates the
larger pump pedal.
b. Alter pumping, remove your 1001 from the "down" foot
pedal and pump the larger pump pedal.
c.
If
there appears to be air trapped in the second stage
ram, pump the jack to maximum extension. Insert an
allen wrench in the small allen socket set screw in the
side of the secondary cylinder nut. See the exploded
view parts drawing for the location of the parts
mentioned. Slightly turn the set screw in a
counterclockwise direction while lightly depressing the
larger pump pedal. This procedure is similar to bleeding
air out of an automotive brake line. Repeat the procedure
until there are no bubbles in the oil that escapes from
behind the allen socket set screw.
d. Close the allen socket set screw by turning il in a
clockwise direction until tight. Repeat steps 'a' and "b'.
e. If the condition seems beller, repeat steps "a' through "d"
until air is purged from the system.
