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!

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. Nobody is to assist the main
operator in the work area - risk of injury!
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. 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.
5. 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.
6. 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.

7. Risk of falling objects
Be particularly aware of the fact that logs may fall down from the rack during use, particularly
during loading and feeding on the wood board. We recommend strongly that you use protective
footwear during this work.
8. Safe loading
Avoid all presence in the risk zone during loading of the rack. Logs may fall off during loading
and cause injuries if you are not attentive during this phase of the work.
You should also avoid loading too much on the board as this increases the risk of fallout during
the practical work of feeding to the cutting board.
