Safety
. Instruction manual
All operators, mechanics and the owner must be well acquainted with the instruction in this
instruction manual before the machine is taken into use.
You should always work with care when you employ agricultural machinery. Read and observe
the safety instructions in this binder. Your safety is your responsibility!
Be particularly aware of warning signs
with this symbol it marks measures
that must be carried out in order to avoid accidents.
The symbol appears in the instruction manual and on
warning signs on the machine.
2. Personal protection equipment
You should always wear hearing protection and protective goggles when using the wood
machine. Further, you should use protective footwear and sturdy work gloves during handling of
the machine and the materials.
3. The safety of the surroundings
Make sure that no-one not concerned are present in the area of work. We emphasize as strongly
as possible that only one person is to handle the machine, i.e. operate the saw chain sword and
the splitter. Nobody is to assist the main operator in the work area - risk of injury!
Never start the machine when there are people or animals close to the machine or the tractor.
Never stand between the tractor wheels and the machine!
The machine’s rotating parts may cause severe injuries.
If other persons than the operator of the machine are present in the risk zone, the operator is to
explain the danger the machine involves.
4. Clothing and the drive shaft
o not work in clothing that may be caught in the moving parts of the machine (for example
scarf, wide coats).
The tractor must be disconnected and the hand brake activated before the shaft is connected to
the tractor’s power take-off. The drive shafts are always to be equipped with original protection
covers.
Damaged and worn covers are to be replaced immediately!
Make sure that all covers for the shaft are in good condition and correctly fitted. Never start the
machine when this is not in order. The locking chains for the plastic covers are always to be
fixed to the appropriate brackets in order to prevent the covers to rotate.
5 Safe connection and use.
Allow nobody to stay between the machine and tractor when the machine is connected to the
tractor. The same applies during use of the machine. Make sure that the connection is carried
out in a safe manner.
6. Safety in case of interruptions and maintenance.
Remember always to stop the tractor’s engine and remove the ignition key before you lubricate,
adjust, clean or carry out repairs. This is to secure that the tractor does not start before you have
completed the operation.

7. Hydraulic high fluid pressure.
Be careful when you work with hydraulics. Wear eye protection and gloves. Hydraulic oil under
great pressure may penetrate the skin and cause serious infections. See a doctor is you have
had had an injury. Ensure that no-one is standing close by when hydraulic functions are
performed.
8. Good lighting – a necessity.
The machine must only be used in daylight that secures a good overview of the operations – or
with artificial lighting which provides good overview of the work area.
Good lighting is very important with reference to safety.
9. Rotating parts – risk of crushing
The machine’s rotating parts may cause severe injuries. The same applies to risk of crushing
during operation.
All covers and protective equipment is to be fitted on the machine during use. The user is
responsible if an accident occurs as a consequence of defective protection.
Avoid all unnecessary stay in the working area when the machine is in operation.
Never put your hand in behind the protective screen even if the saw chain is in back
position.
0. Horizontal positioning and tidiness on the workplace
Always place the machine as horizontally and steady as possible to secure stable working
conditions.
Keep the workplace as tidy as possible. This contributes to generally better safety against
unwanted events.
. Area of application
The machines are only intended for production of fire wood from “pure” wood material without
any contaminants. It is not allowed to employ the machine for other material such as
construction waste and similar with metal parts such as nails, screws and similar. The same
applies for materials that are polluted with plaster and similar coatings. The saw chain is only
designed for wood materials without contaminants.
2. Zero alcohol tolerance
Persons who are under the influence of drink or drugs must not operate the machine. The same
applies to tired people who do not have full control over their movements.

3. Safe transport
Before the machine is moved, the feeder conveyor and transporter (both in an up-right position
as outlined in the illustration) are to be strapped to secure that they do not fall down. The loading
strap has a fixing point at the lower part of the feeding conveyor and secures the conveyor belt
from falling off during transport.
4. Contact with electric wires and similar during transport.
Be aware that the wood machine may be taller than the tractor during transport and there is a
risk of contact with eletric wires, railroad underpasses etc!
If the machine has been set up for splitting of 60cm wood lengths, it should be set back to 40cm
before moving. This is because the machine will protrude on the right side if it transported in
"60cm set-up". If you choose to move the machine in “60cm set-up”, you should be very
attentive of the fact that there is a protrusion beyond the width of the tractor on the right hand
side.
5. Crushing risk – Rotating parts in the transporter
Never put your hands or limbs into the output transporter. This part has rotating parts may cause
severe injuries.
6. Transport conveyor - transporter
Avoid staying under the transporter when this is under tension in order to avoid injuries in case
of any uncontrolled downfall during use. Also avoid contact with the transporter’s moving parts
during use.
7. Safe cutting
Avoid placing your hands close to the saw chain. This is obtained by consequently using the log
holder A and the handle B to operate it.
For cutting the last log of wood, it is important to retain a “suitable” length and cut a shorter piece
as the next to last. uring this operation, it is especially important to use the hand operated log
holder A so that the user does not receive an unexpected backlash from the final piece.
You are advised to use the “count-down ruler” for the last three lengths so that these may be cut
to a somewhat shorter even length than the desired length.
When you want to cut twiggy or crooked logs, it is important to make sure that these are
securely placed. Use the hand operated log holder A as much as possible during cutting of such
wood materials to prevent that fingers/hands are squeezed.
Before start-up after maintenance you should check that all tools have been removed and
brought back into place.
Before the machine is elevated or lowered, you should check that no-one is close to or touch the
machine.
If any warning signs are removed during repair or service, new signs must be fitted
immediately!

Transport and handling before use
The VM420 body is equipped with a fork pocket (A) for handling with fork truck or pallet forks. Be
aware that one individual wood machine weighs about 875 kg. Use lifting equipment designed
for such total weight!
Preparation for moving with tractor.
The transporter is folded together in the joint E. Afterwards, the transporter is moved to an up-
right position by means of the winch wire. uring this process, the protection cover is shifted in
point B Feeding table and the conveyor belt is adjusted to a vertical and horizontal position by
releasing the locking pin in
point G
Securing before moving
Finally, the connection between the feeding table and the transporter should be secured by
means of a strap for this purpose with fixing points as shown in the illustration. This is important
to ensure that the feeding conveyor is kept in place during transport and the connection between
the feeing table and the transporter is safely secured.

Preparations before use
Hydraulic oil - quality.
The machine’s performance will, to a high degree, depend on keeping the hydraulic oil intact.
The greatest elements of risk for the quality of the oil are
•Excessively high temperature which entails poor lubrication performance and risk of faults and
break-down of expensive components such as valves, pumps and motors.
•Condensation which is formed during conditions including humid air combined with temperature
fluctuations. (the oil tank breathes through the filter and sucks in humid air)
•Condensation water in the oil has the same effect as excessively high oil temperature.
Condensation appears mainly during use in conditions involving humid air and temperature
around 0°C. The oil tank is equipped with a draining plug for changing oil and checks for
condensation.
Oil level check.
The machines are filled with 78 litres hydraulic oil from the factory. Recommended oil quality is ISO VG46
(viscosity group 46). Examples of such oils are Ambra Hydrosystem 46 HV, Mobil TE15m, Statoil
Hydraway HVXA46.
The oil level must be checked by observing the sight glass A which is fitted in the suction grille for the
hydraulic oil tank.
Oil temperature check
It is very important to keep track of the oil temperature B and avoid situations where it exceeds 70
degrees. This situation may occur during unfavourable operating conditions for example in case of too
high rotational speed during use.
If the temperature exceeds 70 degrees, the machine must be stopped until a lower temperature has been
“established”.
If the machine has had excessively high hydraulic oil temperature, the oil must be changed.
This is an unconditional requirement in the guarantee provisions.
Condense check
The oil tank is equipped with a drainage plug C in the bottom. Grey oil is an indication of water in the oil.
In case the oil is polluted with water, all the hydraulic oil must be changed.
Beyond such conditions, the hydraulic oil must be changed every year or after 500 operating hours
(whatever occurs first).
Drive shaft
The requirement for the length of the drive shaft will vary in pace with the size of the tractor and the
length of the steady-braces.
If there are operating angles from 25 degrees and upwards, you should employ a category 6 shaft to
ensure long service life.
If there are great angles, it might be advantageous either to lower the tractor or elevating the machine. It
may be elevated by means of the supporting legs which is standard equipment fitted in the corners and
elevate the machine up to 80mm.
Ensure that the pto shaft had sufficient length. The profile tubes in the shaft are to, after any cutting,
overlap by half the tube length. Any cutting of the shaft must be executed in accordance with the
instructions for such operations – the cut must be trimmed for burrs both on the inside as well on the
outside and the profile tubes should be well greased. Too short telescope length of the shaft entails a risk
of overload of the tractor’s power take-off and the gearbox of the VM420.
Please lubricate the PTO drive shaft before use.
The locking chains for the plastic covers are always to be fixed to the appropriate brackets in order to
prevent the covers to rotate.
The drive shaft must be maintained and used in accordance with its instruction manual.
In order to obtain better operating angle, you may let the machine stand by itself and place the tractor at
a distance and employ a longer drive shaft during operation.

Preparation of the transporter.
The transporter is prepared for operation by
1. Releasing the strap fixing point and loosening the strap at the points outlined in the
illustration.
2. The transporter is put in place by releasing the winch and the wire which holds it in place
– the transporter will fold out until it is level with the ground.
3. Afterwards, the transporter is folded out in its full length in the joint E.
4. The transporter is elevated to the required height by means of the winch.
Preparation of the feeding conveyor
The feeding conveyor is folded in place by releasing the locking pin at letter G which locks it.
The belt is tensioned by adjusting the screws at letter H. The belt is sufficiently tensioned if it
feeds in the wood without friction. Too hard tensioning increases the wear of the belt and
reduces the service life considerably.
An indication of what is suitable tensioning is when the belt in the middle of the feeding table,
allows for 30-40mm – Re. Illustration 4, letter I.
