1. INTRODUCTION:
Before using the AP silage cutter, please read this manual carefully. Get acquainted
with the regulations. Controlling an AP silage cutter which you are not acquainted
with can cause accidents.

Provide this manual to anyone who controls the AP silage cutter.
AP Machinebouw B.V. reserves the right to carry out adjustments in design and
executions to any of the by AP produced silage cutters, without any obligation
regarding formerly delivered AP silage cutters.
1.1 Options within the manual:
The AP silage cutters can, either by the manufacturer or by the dealer, be
equipped of several options such as:
hydraulic push-off system (HA), hydraulic push-off system with folding base (HAN),
removable inlay (IB) and several types of hydraulic valves to adjust the oil and the

3. PRODUCT INFORMATION:
3.1 General:
The AP silage cutter is developed to take out all sorts of ensiled forage products
and is ideal for the loading of mixing wagons, dose wagons etc. It can also be used
to tank out dung from stables.
The AP silage cutters with the type codes NP 1600 and NP 1800 are constructed in
such a way that they can be mounted on practically every wheel loader, telescopic
loader or tractor with front loader, provided that the tractor has a power of at least
50 kW (also see ‘technical specifications’).
AP Machinebouw B.V. strongly advises to only use the silage cutter in combination
with a four-wheel drive tractor.
Furthermore these types of silage cutter can be used in combination with a rough
terrain forklift, provided this is equipped with the proper hydraulic connectivity
options.
The AP silage are delivered with attachment plates and, possible quick change
hooks. Your dealer or AP can mount the appropriate attachment system suitable for
your tractor front loader, wheel loader of telescopic loader. The manor of
attachment of the AP silage cutter can therefor differ per type front loader and
wheel loader. We refer to the manual of your tractor front loader, wheel loader or
telescopic loader.
3.2 Precautionary measures:
General regulations:
*It is strictly forbidden to transport persons or animals with the AP silage
cutter.
*Never climb into the AP silage cutter.
*The user of the AP silage cutter must keep all bystanders out of the working
area of the combination.
*This manual should be available to every person who uses the AP silage
cutter;
*The owner of the AP silage cutter is responsible for the tractor, wheel
loader or telescopic loader and the AP silage cutter to meet the standing
regulations if the combination is on the public road.
* Follow all the rules and regulations which are mentioned in the manual of
your tractor front loader, wheel loader or telescopic loader.
* Before you step down the tractor, wheel loader or telescopic loader always
check the hand brake and make sure that the gear of the tractor, wheel
loader or telescopic loader is in neutral.

* Be careful when you work on sloping surfaces and / or on uneven terrain and
make sure you keep enough stability.
* When you drive on the public road with the AP silage cutter the general
traffic rules are valid. In principle, the AP silage cutter provides no danger
on the public road. Make sure that the cutting frame of the silage cutter is
completely closed and that the lifting arms of the front loader, wheel loader
or telescopic loader are adjusted so low that they do not obstruct the view
(see image 1).
* It is not allowed to use the AP silage cutter on the public road for
transportation purposes.
*If oil leakage appears in the hydraulic system, the oil can penetrate the skin
and cause heavy injuries. Never try to close a leakage by hand. Immediately
contact a physician when someone gets hurt.
* It is strictly forbidden to alter the adjustment of the pressure relief / safety
valve, this can i.a. lead to damaging of the system and / or personal injury.
* Make sure that all coupling pins, if present, are provided with original and
undamaged safety bolts.
* Only couple the AP silage cutter with the regulated means. Be careful during
coupling and uncoupling of the AP silage cutter.
*In the absence of a quick release system, during the coupling or uncoupling
of the silage cutter to the three-point-linkage, front loader, the lifting arms
of the wheel loader or telescopic loader, switch off the engine and engage
the parking brake.

4. INSTALLATION:
4.1 Transport regulations:
If the AP silage cutter is being transported separately from a tractor / mini loader,
the cutting frame always must be closed. This is to avoid injuries to limbs by the
tines and / or knives of the AP silage cutter and to avoid damaging to the hydraulic
cylinders. Make sure that the parts of the hydraulic system (among which the hoses)
cannot be damaged.
If you want to transport the AP silage cutter on a lorry (or anything similar) you
have two possibilities:
1: You put the AP silage cutter on a pallet, tie it down and places it with the
help of a forklift truck on the lorry.
2: You hoist the AP silage cutter with the help of a pulley on the lorry.
WARNING: Use solid hoisting material and fix the hoisting cables / chain(s)
always in such a way, that the AP silage cutter remains a good
stability during the hoisting.
During transport on the road the customer must pay particular attention to the
lighting of the AP silage cutter (see safety regulations).
4.2 Assembly regulations:
The AP silage cutter is fully operational delivered by AP Machinebouw B.V.,
excluding possible attachments for your tractor front loader, wheel loader or
telescopic loader. This attachment system will be attached to the silage cutter by
AP or your dealer, based on the specifications you gave of the tractor front loader,
wheel loader or telescopic loader. There are no further specific assembly
regulations.
AP Machinebouw B.V. does not take any responsibility for replacing of spare parts
by the user, in that case the warranty expires. Replacing of spare parts must be
done by the AP dealer.
4.3 Hydraulic connections:
4.3.1 Silage cutter in combination with tractor front loader, wheel loader or telescopic
loader:
To control the AP silage cutter without hydraulic push-off system your tractor front
loader, wheel loader or telescopic loader only requires one double functioning
control valve. If your silage cutter is equipped with a hydraulic push-off system your
tractor, wheel loader or telescopic loader requires a twofold double functioning
control valve.
The specific operation of the control valve(s) of your tractor front loader, wheel
loader or telescopic loader with regard to the control of the silage cutter is non-
universal and therefore cannot be specified in this manual.
