Safety regulations
1. Use caution and patience
when servicing the harvester
head.
2. Immediately report any
malfunctions in the head to
your foreman or the person
responsible for servicing.
3. The engine should be shut off
during servicing.
4. Avoid working alone.
Keep a mobile phone near

harvester outside the cab.
Store an emergency alarm
number in one of the quick
select phone numbers.
5. Service the harvesting head
according to the
manufacturers service
schedule.
6. If you are not familiar with the
construction of the machine,
ask the manufacturer for
instructions before beginning
to service or repair it.
7. Danger to life!
Never attempt to service the
head near the range of
movement of the saw, the
delimbing knives or the feed
rollers when the engine is
running.
Safety while servicing and repairing:
8. Danger to life!
When servicing the head,
make definitely sure that
nobody starts the harvester!
If the harvester is started, the
knives and rollers will close,
the saw will return to its home

equipped with a precontrol
solenoid which allows the
directional valve to be
controlled manually by
pressing the end spindle.
9.1 Danger to life!
Avoid using the manual
control when troubleshooting
or repairing the harvester
head. If maual control is
absolutely necessary be
extremely caution.
9.2 Do not use the manual control
to tilt the harvester head or

9.3 Be sure of the correct valve.
Beware of the spinningmotion
of the feed rollers and the
movement of the delimbing
knives and the saw bar.
