5.
Bolt the base to the tray using the six ½" x 2" bolts, flat and spring washers and nuts.
6.
Position the boom lugs on the closed end of the boom either side of the top of the boom
post on the same side as the ram mounting lug and insert the pin.
7.
Position the lugs of the ram on either side of the lug on the boom post and insert the 1”
pin. Push the retaining clip home. Position the rod end clevis of the cylinder to the boom
in the same way. The ram ports should be on the topside of the ram.
8.
Secure the lifting hook to the boom with the pin. Push the retaining clip home.
9.
The power unit is the best installed under the tray so that load space is not reduced and
the unit is protected from damage. On most vehicles the unit is installed under the front
end of the tray on the same side as the base.
In choosing a position these points should be observed:
a) The reservoir end of the unit extends further from its mounting bracket than does its
motor. When space is limited, rotating the unit and bracket may improve installation.
b) The unit and bracket should clear any extreme movement of the vehicle drive shaft
and suspension.
c) The unit should be level and accessible for servicing (i.e. oil top-up). Some access
difficulty is to be expected.
d) The position should not require excessively long lengths of hydraulic hose or power
cable.
e) The mounting bracket can be adjusted by light bending to suit different spacings
between tray bearers.
10.
With the mounting bracket in position mark the tray bearers through each of the end
four holes.
11.
At each of the marked points drill a 7/16” hole through the bearer.
12.
Do steps 13 to 19
before
installing the bracket under the tray
13.
To prevent unauthorised use of the crane the handset control should be located inside
the vehicle cab. Locate a suitable rubber grommet in the cab wall behind the driver's
seat and pass the control cable through the grommet. Route the control cable from the
cab to where the power unit is to be installed ensuring that the control cable is protected
from damage.
14.
Remove the plastic plug from the power unit pump and screw in the hydraulic nipple
fitting. Connect the elbow end of the hydraulic hose and check connections for
tightness.
15.
Bolt the power unit to the mounting bracket with the two 10mm bolts, flat & spring
washers. Through the bottom of the bracket into the base of the pump.
16.
Fill the oil reservoir with 2.2 litres of hydraulic oil.
Important:
For steps 17 and 20 study illustration 1.
17.
For 12 Volt and 24 Volt power units:
(a)
Remove the large nut and washer from the terminal on the side of the Start Solenoid,
attach both the red wire from the Remote Hand Control and one end of the red 3.5
metre power cable, replace the washer and nut.
(b)
Attach the black wire from the Remote Hand Control to red wire coming from the
lowering solenoid using connector supplied.
(c)
Attach the green wire from the Remote Hand Control to the small terminal on the Start
Solenoid.
18.
Bolt the mounting bracket to the bearers or some suitable position.
19.
Route the power cable from the power unit, forward under the tray, along a suitable
path under the cab and up to the vehicle battery, ensuring that it is protected from any
damage (e.g. chaffing burning on engine manifolds). Use cable ties to retain as
required.
20.
Attach the earth strap to the negative post on DC motor, as in illustration 1. Attach the
other end of the earth strap to the vehicle chassis. The pump must be earthed to the
