2. Secure the air duct to the blower with the M8 x 25 nuts, bolts and washers
provided.
3. Locate the pesticide feed hose and attach the free end to the inlet fitting at the
bottom of the flow control valve (1 in Fig. 2).
4. Route the hose and secure in position with the cable ties provided. Leave a
small loop of hose adjacent to the air duct support hinge to prevent fretting
against the hinge pin.
3.2. Installation on Tractor
The AU8500 is designed for installation on an ISO standard category 2 3-point
implement linkage on an agricultural tractor. If necessary, the linkage should be
fitted with adaptor balls with the following internal diameters:
Upper ball
25 mm diameter
Lower balls:
28 mm diameter
The user must provide a suitable telescopic PTO drive shaft to connect the shaft of
the gearbox to the PTO shaft of the tractor. The length and specification of the shaft
will depend upon the tractor being used. The shaft should be specified as follows:
Length:
Select or cut as required to provide a minimum of 25 mm
and maximum of 200 mm additional compression
(closure) when the shaft is at its shortest length (gearbox
shaft and tractor PTO shaft at the same vertical level)
Internal splines:
To suit tractor PTO shaft at tractor end, 33 mm outside
diameter, 6 splines at sprayer end
The procedure to mount the sprayer is as follows:
1. Remove the binding wire or bolts securing the sprayer to its shipping pallet.
2. Attach the sprayer to the 3-point implement linkage of the tractor, using the pins
and locking clips provided. If necessary, move the pins for the lower attachments
to alternative holes in the sprayer frame to suit the geometry of the linkage.
IMPORTANT: If installing the sprayer on a light-weight tractor, it may be
necessary to fit balance weights to the front of the tractor. See tractor
owner’s handbook for further details.
3. Fit the PTO drive shaft between the tractor PTO shaft and gearbox of the
sprayer. Ensure that the locating pins are correctly engaged on the splined
shafts at each end.
4. Secure the outer safety sleeve of the drive shaft to the structure of the tractor at
the tractor end, using a suitable chain. The chain must be adjusted to prevent
rotation whilst allowing the necessary vertical movement of the drive shaft.
