SAFETY INSTRUCTIONS
FOR HYDRAULIC CIRCUITS
Work on hydraulic equipment may only be
carried out by professional hydraulic engineers.
Be cautious when using the equipment in cold
conditions.
Check the machine for leaks. Do not use the
machine if there is a leak from any system.
Check all hydraulic hoses – particularly those
which are bent during use – and replace any
that are in poor condition or have leaks. Ensure
that all joins are tight and that the lines are not
damaged. Check that all protective caps and
ller caps are closed properly.
Check that all hose connectors, lengths and
qualities comply with applicable requirements.
When replacing or repairing hoses, use original
parts or hoses and connectors recommended
by the manufacturer. Check particularly that the
pressure classes of the hoses and connectors
are suitable to the operating pressure levels.
Check that all safety devices such as pressure
relief valves, etc., are in place and work properly.
Familiarize yourself with their use.
Safety systems may never be bypassed.
Check the main hydraulic parts daily, and
always after a fault. Replace any damaged
parts immediately.
If a component is damaged, clean it before
repairing it. Do not use solvents when cleaning
parts.
Do not attempt to carry out repairs that you are
not fully familiar with.
Never carry out repairs of the hydraulic circuit
when the system is pressurized. When
pressurized, the oil spray can penetrate the skin
and cause mortal danger.
Never work below a device or component that is
only being held up by hydraulics.
Use separate supports when carrying our
maintenance or repairs. Do not disconnect
cylinders or their valves until the machine is well
supported.
Most hydraulic oils do not evaporate easily. Risk
factors include hot oil, spills and oil mist
(pressurized).
If oil gets into your eyes, rinse with plenty of
water and contact a doctor.
Avoid prolonged or repeated contact with your
skin.

If sprays or contact with the skin cannot be
avoided, use protective gloves, goggles and
clothing as necessary. Do not use oily clothing.
Avoid discharging hydraulic oil into the
environment, as it can pollute waterways and
the groundwater. When working in ecologically
vulnerable areas, use biofuel.
Store the oil in sealed containers provided by
the manufacturer. Try to transfer the oil directly
from its container into the tank.
If the oil must be passed through other containers,
ensure that they are completely clean. Caps,
funnels, sieves and lling holes must also be
clean.
Never store oil outdoors, as water could condense
in it.
Always dispose of oil in a suitable container,
never into the environment!

INTRODUCTION
The Farmi CH380 is a 4-knived chipper desig-
ned for grapple loader feeding of up to 380 mm
diameter stems. The chip size can be adjusted
to suit its various end uses, such as biofuel,
industrial raw material, soil improvement or dry
litter.
The HF380 hydraulic feed chute facilitates pro-
cessing of difcult to feed materials. The feed
chute comes standard equipped with No Stress
revolution control, which shuts down the feed
when the output Rpm drops too low. The bene-
ts of the No Stress mechanism are:
• tractors of lower power rating can be used
• more homogenous chip quality
• higher chip yield
The CH380HF chipper has its own hydraulic
unit.

SHORTENING THE PTO SHAFT
1. Connect the device to the tractor’s 3-point
hitch.
2. Lift the machine with the hitch so that the
distance between the splined shafts is at its
shortest.
3. First cut the thicker shaft shield to the
correct length. Remember to leave a 40 mm
clearance. Next, cut a similar length from the
prole tube. Shorten the other half of the
PTO shaft in a similar manner. File off
the burr.
4. Interconnect the tubes and check
that the shaft is sufciently shortened
by carefully lifting up and down with the hoist.
Ensure that the shaft has a 40 mm
movement clearance. Also move
the machine sideways to check that the shaft
moves freely.
