FARMI 380 HFC / HF
20
CHIPPING
FARMI 380 HF is designed only-
for grapple loader feeding. The
danger area radius is 20 m. Ensu-
re that the danger area is clear of
people.
1. Make sure the feed chute is empty.
2. Turn the manual switch to the feed position FF (or
press the right-hand foot pedal).
3. Check before feeding material into the chute that
the material to be chipped contains no nails, sto-
nes etc.
4. Feed the wood into the chute using a grapple
loader. Release the grapple as soon as the feed rol-
lers begin to draw in the wood.
5. If necessary, adjust the rotational speed of the feed
rollers, see the section ”Feed speed control”.
6. Discontinue feeding while adjusting the
discharge direction.
7. If you need to remove wood from the feed chute in
the middle of chipping, turn the manual switch to
the reverse position REV (left foot pedal). Keep the
switch in the REV position until the feed roller re-
leases the wood.
Oil heats up as it circulates
through the hydraulic pump,
motor and valves. Check the oil
temperature twice each hour to
prevent overheating. If the oil
heats excessively, stop chipping
and allow the oil to cool.
STOPPING THE CHIPPER VIA THE TRACTOR DRIVE
Slow the tractor rpm to idling speed before disenga-
ging the PTO. Move the PTO control lever slowly to the
OFF position.
FEED SPEED CONTROL
The hydraulic system is equipped with a double pump.
The output of one pump can be directed either to the
drive or to the tank via valve (A).
When the chip size is big (20-30 mm, 540 rpm), both
pumps must be in use (lever in position 2). When the
chip size is below 20 mm (1000 rpm), use only one
pump (lever in position 1).
There is a danger of system over-
heating if both pumps are used
at the same time when the chip
size is below 20 mm (1000 rpm).
Fine adjustment of the feed speed is performed using
a flow regulator. When you turn the button in the an-
ticlockwise direction, the feed roller rotates faster.
When you turn the button clockwise, the feed roller
rotates slower.
The speed is optimal when the wood does not push
against the chipping disc and the feed roller does not
slow down the feed.
Do not adjust the feed speed
while feeding wood into the
chipper. The valve can become
damaged. Adjust the feed speed
when the rollers rotate unloa-
ded.
