9. TAKING A NEW MACHINE INTO USE
9.1
PREPARATIONS PRIOR TO OPERATING
A new machine must be brought into a proper operating condition by the operator prior to the
machine's first use. If the chipper is delivered with its discharge spout independently packed, the
attach the spout to the machine as follows: Place the spout on its mountings in such a manner
that the guide lug on the spout lines up with recess in the mounting adaptor. Secure the spout in
its place by means of the enclosed split clamp and its knurled nut. Turn the nut until it is tight.
When taking the chipper into use make sure that all the safety panels are in place, that no
foreign matter is left inside the feed orifice and that the disc rotates freely. Before connecting the
machine and its drive to the tractor check the instruction manual notes on the PTO shaft and
proceed accordingly. Only after observing these points may the chipper be coupled to the tractor.
9.2
DISCARDING PACKAGING MATERIALS
The wooden and cardboard packaging materials may be disposed of by burning or taking them
to a dump site. The polyethylene bags and plastic cords should be disposed of either by recycling
them according to national regulations or by taking them to a dump site.
TRACTOR PTO
The starting of the chipper should be made smoothly on low rpm due to the large rotating
masses inside the chipper. During operation, the chipper cutting flange speed must be kept
within the range of 540-1000 r.p.m. The universal drive shaft has been discussed separatively in
the chapter titled "PTO SHAFT".
HYDRAULIC SYSTEM
The M chipper model HJ 10 M and HJ 10 SLT do not require SL use of the tractor hydraulic
system as the model has no actual feeder mechanism and the model features its own
independent hydraulic circuit for its feeder mechanism drive, which in turn is driven by a set of
Vee-belts from the chipper knife flange shaft.
The HJ 10 SLT model requires, hydraulic oil from the tractors hydraulic system 1.3 - 5 gal./min
(5 - 20 L/min) and a single control valve, fitted with single pressure and return connectors
for its operation.
9.3
ATTACHMENT TO A TRACTOR
The chipper is designed for attachment to tractors equipped
with category 1 or 2 lower links (i.e. either with 22 or 28 mm
attachment pins).
In the delivery condition the chipper's mounting links have
been raised into vertical positions. They must be lowered
down and secured in the position as shown in the
accompanying figure on the right. The length of the
mounting links can be adjusted by the set of alternative
attachment holes in the links.
The tractor lower links and the top link are attached to the
chipper mounting points in the normal manner and the
lower links secured in their centre position by means of their
stabiliser.
