1 Introduction
1.1 Getting Started
Thank you for choosing this TREJON MULTIFOREST product. We have concentrated on
making a powerful and good machine that will serve you for many years. As the service life of
the machine does not wholly depend on us, but also you, the user, we have compiled an
instruction manual in which we describe its correct care and use. So read through these
directions thoroughly. Always get in touch with the dealership where you bought your machine
when ordering spares or other service. The dealer is your natural service partner. When
ordering spares, always specify the correct model, type and serial number found on the name
plate on the chassis.
1.2 Description
This MULTIFOREST product is an all-round crane for small-scale forestry, agriculture and light
work in the construction sector, where flexible and simple lifting machinery is required.
MULTIFOREST cranes are available both as parallel (P-series) and knuckle boom (V-series)
types, each of which has its own specific advantages.
The crane is supplied with suitable flow and pressure from an external hydraulic system (see
Technical Specifications).
It is available as a separate machine or mounted on a MULTIFOREST trailer. When mounting a
separate crane, it is the buyer’s responsibility to make sure the carrying vehicle is of a suitable
size and stability. This is to avoid tipping the machine or in any other way putting people or
nearby equipment in harm’s way. It is also the buyer’s responsibility to ensure that the
coupling to the carrier vehicle is dimensioned with good safety margins so it can handle the
stresses involved.

Lifting and lowering of the machine.
Be careful when lifting and lowering the machine/machine part.
Stability. The machine must not be operated with a tractor that does not weigh enough over the
front/rear axle so that tractor stability is affected. At least 20% of the tractor weight shall rest on
the front axle to ensure tractor steering and braking ability.
Mount ballast weights if necessary, see tractor instruction manual.
Apply the support legs when working with the grapple loader (consider retrofitting if not
mounted) and first load the smallest and closest logs so that the trailer attains good stability
before starting to load the heaviest logs.
Operating the Machine. Take great care when working on uneven ground conditions, close to
ditches and fences, look out for hidden dangers and adapt your working rate.
Great care should be observed when working on steep slopes:
Try to drive in the same direction as the incline and not across it.
Avoid fast starts and heavy braking when driving the machine up and down inclines.
If it is absolutely necessary to drive across steep inclines then reduce your speed and watch out
for unevenness, avoid sudden turns and be aware of the shift in centre of gravity that occurs
when lifting mounted tools.
Hold onto the steering wheel tightly if the tractor should overturn.

Safety during maintenance and service. The machine must be standing on firm, even ground
for maintenance and adjustment.
The tractor engine must be shut off, all moving parts stationary, the machine lowered to the
ground and the handbrake applied during all cleaning, inspection, adjustment, maintenance and
repair work.
Clean the machine thoroughly before repair and storage.
Bearing and hydraulic components should not the cleaned with high-pressure jets.
If excessively high pressure is used for general cleaning, this may damage the paint.
After cleaning, the machine must be lubricated according to the lubrication schedule and a short
test run carried out.
Vibration. If any vibration should occur in the machine, it must be shut down immediately and
the cause located. Change any damaged parts.
Hydraulic Hoses. Hydraulic hoses on the machine contain oil at very high pressure. Do not
touch hoses and hydraulic components if the system is pressurised. In case of leaks, oil at high
pressure may penetrate the skin and cause serious injury. In the event of an accident, contact a
doctor immediately.
Check the condition of hydraulic hoses with respect to damage. Chafed and leaking hoses
should be replaced immediately with new that meet the manufacturer’s technical requirements.
When changing tractor, always check the length of the hoses. When hoses are too long or too
short, they may be damaged.
The use of incorrect hydraulic hoses that do not meet with specifications is strictly forbidden.
Hydraulic motors and hoses can get extremely hot while in operation, with a risk of burn injuries.
Do not loosen hoses while the oil is hot, wait for it to cool down.
Welding. Protect bearings, hydraulics and electronic components if welding is being carried out.
Before welding commences, electronic components must be disconnected and the welder’s
ground clamp placed as close to the welding site as possible.
Fire Risk. If overheating of machine parts should occur, the cause must be located and the
machine shut down. Forest residue is very flammable, so remove forest remains and dirty oil.
Keeping a fire extinguisher nearby is recommended.
Smoking in the vicinity of the machine is forbidden.
Electrical Lines. Take great care when working close to electrical lines, maintain a safe
distance with good margin.
If an accident should occur and the crane comes into contact with live lines.
-Keep calm, act rationally so as not to worsen the situation and do not touch any metal parts.
-Warn people in the vicinity and make sure they stay outside the risk zone.
Radio control.If you are using the crane with remote control, you must follow the regulations
and instruction given in the radio control user instructions. You can use the crane only from the
tractor cab in this case, or from outside at a minimum distance of 10 m from the machine.
Spare Parts. Use only original spare parts on the machine.
If you should have any questions concerning the machine or its function, please get in touch
with your dealer or Trejon AB

3 Using the Machine
3.1 Assembly
Warning!
Crush risk. Do not stand between machine and tractor when coupling. Always apply the
brake on the tractor when leaving the cab during all coupling and uncoupling.
The machine may only be coupled to a tractor/trailer with sufficient weight over the front
and rear axle respectively so that steering and brakes are in working order when the
machine is coupled. Use ballast weights as necessary, see the tractor’s instruction
manual. When working with a grapple loader, use the support legs (consider retrofitting if
not mounted).
The temperature of the hydraulic oil must be checked during operation. If the temperature
rises too high, the reason should be located immediately to avoid serious damage.
If the crane’s valve package is to be mounted inside the tractor cab, protection must be
installed to prevent oil at high pressure reaching the operator, e.g. after a hose rupture.
NOTE!
Ensure no-one is inside the risk area when lifting.
Take care with straps and wires when they are removed as they are tensioned very hard.
They can also be very sharp.
The hydraulic system to which the crane is coupled must be unconditionally fitted with
an efficient filter on the return side.
Trouble-free operation presumes the hydraulic system to be in good condition and that
maintenance has been carried out as recommended.
The crane is normally function tested before delivery. The cylinders may therefore
contain some test oil.
Delivery and return hoses must not be coupled to double-acting outlet.
Instead, the return hose shall be coupled to a separate pressure-free return outlet.
