4. Slowly raise the truck carriage completely to engage
the top hooks with the truck carriage. Tilt carriage back
until the unit is against the carriage bottom fork bar (0
degrees).
7. Inspect for proper engagement of the locking lug in the
corresponding notch of the truck’s carriage. Inspect
any wear strips, if applicable, to insure they are prop-
erly aligned in the top hooks.
8. Weld on the optional supplemental locking lug that
is supplied with the attachment, (two pieces of 1/2" x
1/2" x 2.00" steel included with the attachment) with
either E-6011 or E-6013 welding rod, or equivalent,
on each side of the truck carriage. (Figure 4-2)

10. If quick hooks are installed, simply raise the slide plate
until the button clicks into place.
WARNING
Equipment failure hazard.
The attachment could fall off the truck if
the quick hook is not properly installed.
Slide plate must click into place. If the slide
plate does not click into place because
the truck carriage prevents the slide plate
from being raised up high enough, install
shims between the attachment and the
body of the quick hooks.
11. To ensure proper locking of the slide plate, use a
screwdriver to try to pry down the slide plate. If the slide
plate is not locked in place, inspect and correct any
cause that might restrict the slide plate from going up
enough to allow the button to become fully engaged.
12. Apply grease to bronze top hooks through fittings and
spread on entire slide area of mid plate.
13. Check all fittings, connections and bolts for any
interference.
4.3 Hydraulic Connections
1. Before connecting the truck hydraulic system to the
attachment, the system
must
be purged through the
filtration system. This will eliminate any contamina-
tion that might exist in the auxiliary hydraulic system
of the truck.
2. Purge the system by installing a jumper line
and operating each hydraulic function (clamp,
rotate and side shift, if equipped) in each direc-
tion for a minimum of 30 seconds. (Figure 4-4)
Hoses should meet or exceed SAE100 RI Type AT,
with maximum working pressure of 3,000 psi for all
attachment functions.
