TRANSPORTATION AND TRANSFER
Always observe the Road Traffic Act when driving on public roads.
Inspect and install all equipment required for transportation on public roads, such as
lights, reflectors and the slow vehicle triangle.
Observe maximum shaft weights, total weights and transportation dimensions allowed.
All devices moving the machine, such as chains, racks etc., must be placed so that
involuntary movement cannot affect them in the machine working or transportation
position.
The machinery or additional weight in tow or on the lifting device may affect the behaviour of
the tractor during transportation, i.e. its control and the operation of the brakes. This is why it
is important for sufficient control and braking action to always be available.
Passengers may not be transported on top of the machine.
The machine may only be lifted at the points indicated with instruction stickers.
Only use approved lifting straps or chains and check to ensure they are in good condition.
If the machine is moved e.g. onto a platform, it should be secured with chains or straps.

danger of it falling.
Safety Instructions
4.4 UNIVERSAL DRIVE SHAFT
-
Always switch the power take-off drive when leaving the tractor cabin.
Ensure that the PTO shaft's safety tubes do not rotate with the shaft inside. Carefully attach the
Check chain.
When the machine is transported on public roads, the driver should ensure that the PTO has been
switched off.
Before the power take-off is switched on, ensure that no one is standing near the rotating
PTO shaft.
The universal drive shaft may only be installed once the PTO shaft of the machine has been switched
off, the engine has been stopped and the key has been removed from the ignition switch.
When starting the engine, the power take-off must be switched off.
The tractor power take-off rotational speed must correspond to the operating speed rang
of the machine's drive mechanism.
The limits set for the PTO rotational speed must be fully observed. Speeds exceeding the
limits will damage the machine.
The PTO shaft should be switched off when not needed or when the tractor and the machinery are at
a very steep articulation angle.
Before the universal drive shaft is switched on for rotation and during its rotation, ensure that no one
is in the danger area of the rotating drive shaft.
Only use CE-labelled universal drive shafts approved by the manufacturer. All PTO safeguards, shields
and the tractor PTO guard must be in place and in good condition.
Never use a damaged drive shaft, since this involves a serious risk of accident.The damaged
shaft should be repaired before it is used again.
Please note that the shaft tubes of the drive shaft overlap in both the transportation and
the working position.
After the drive shaft is shortened, the splined ends should be cleaned and carefully greased.
The universal drive shaft should only be installed and removed when the tractor power take-off shaft
is switched off. Never use the switch alone to disengage the transmission drive to the PTO.
Once the universal drive shaft has been installed, its securing peg must engage in the locking position
in the POT shaft groove. Ensure that the shaft is securely in place.
Attach the drive shaft shield securing chain so that the shield cannot rotate.
Place the removed drive shaft on a suitable support.

HYDRAULICS
After the connection, the hydraulics system is under high pressure. Hydraulic oil released with
high pressure will penetrate the skin and may cause serious injuries. There is also a risk of injury
when searching for leakages.
Be careful with all hydraulic components. They involve the risk of getting cut or trapped between
components.
When a hydraulic hose is connected to the tractor, the hydraulic systems of both units must be
Non-pressurised.
PROTECTION FROM OIL AND GREASE
-
When handling oil or grease, always wear appropriate protective clothing and oil-resistant gloves.
Avoid skin contact with oil and grease. This may cause skin injuries.
Never use oil or lubricating grease to clean your skin. These substances may contain small
metallic particles that cause wounds which are worsened by the oil.
Follow the handling and safety instructions issued by the lubricant manufacturers.
Synthetic oils are often corrosive and can cause severe irritation of the skin.
WASTE OIL
Collect the waste oil and dispose of it in accordance with national regulations.
ACCIDENTS
If oil is dispersed in the soil, prevent it from spreading and collect it, for example, by
absorbing it with peat.
If you have skin injuries caused by oil or a lubricant, consult a doctor immediately.

OPERATING ENVIRONMENT
6.1
INTENDED USE
The purpose of a chipper is to produce chips from trees which are suitable to be fed into the chipper's
feed orifice based on their diameter and other measurements. The wood material must be clean. Dust,
sand or soil quickly wear down the blades. Metal objects, such as nails, will cause denting of the blades.
Larger metal objects may damage the chipper.
For other types of use such as chipping down cardboard rolls, plastic piping or hard boarding panels,
please contact your dealer.
6.2
LIMITATIONS OF USE AND PROHIBITED USES
Limitations regarding the machine operator
-
The machine operator may not be under the influence of intoxicating substances, alcohol o
strong medication.
In cases of illness or permanent disability, the doctor in charge should be consulted for a
permission to operate the machine.
The use of the chipper is prohibited for persons without the sufficient level of knowledge and
skill required to operate the machine and for persons under
the age of 15.
Prohibited uses
The chipper may not be used in nature reserve areas.
The machine may not be used to spread liquids, inflammable materials, sand or fibrous material.
Avoid using the machine in areas where its use could cause inconveniences in surrounding areas
Due to excessive noise or the spreading of dust.
Chipping highly inflammable materials is strictly prohibited.
Never feed a chipper with loader feeding equipment by hand because of the risks presented in
chapter 5.
The safety distance of a chipper with loader feeding equipment is the same as the safety
distance of the crane or at least 20 m.
7
PRINCIPLE OF OPERATION
When chipping wood with a chipper not fitted with a feeding device, the blades mounted on the blade
disc draw in the wood automatically. The feeding speed depends on the knife setting: a short knife
setting results in a small chip size and a slow intake speed, whereas a large knife setting results in a
large chip size and consequently, a high intake speed. The chips produced are ejected through the blade
orifices to the blower fan and into the storage through the discharge spout. In chippers equipped with a
feeding device, the intake is boosted by feed rollers driven by hydraulic motors. The hydraulic motors
are pressurised by the tractor hydraulic system or by an independent hydraulic system via a control
valve. The feed of the hand-fed chipper is controlled wiht a feed control lever which has 4 positions:
Stop, Feed, Stop and Reverse (outward-inward).
8
Operating Environment
The feed of a chipper with loader feeding equipment is controlled with an electric remote control,. The
manual for the remote control is delivered with the loader feeding equipment. Never feed the chipper
with loder feeding equipment by hand as it poses a serious risk of injury because the feed hopper does
not include any safety equipment.The safety distance of a chipper with loader feeding equipment is the
same as the safety distance of the crane or at least 20 m.
The chippers with loader feeding equipment, HJ 250 and HJ 261, can be attached to Junkkari cranes
P3151, P3162 or P4169 by using fittings. The picture below shows chipper HJ 250 in a trasnportation
position.

IMPLEMENTATION
9.1
PREPARATIONS PRIOR TO OPERATING
The customer shall prepare the chipper prior to operating. If the chipper is delivered with its discharge
spout removed, the spout shall be mounted onto the machine.
When taking the chipper into use the customer should ensure that all the safety panels are in place,
that no foreign materials are left in the feed orifice and that the disc rotates freely. Before connecting
the machine to the tractor, the user should check the instruction manual sections on the universal drive
shaft. The chipper shall be coupled to the tractor with the equipment described above.
9.2 PACKAGE DISPOSAL
The wooden and cardboard packaging materials may be disposed of by burning or by taking them to a
landfill. The plastic bags and cords included in the packaging materials should be disposed of either by
recycling them according to national regulations or by taking them to a landfill.
9.3 ATTACHMENT TO A TRACTOR
The chipper is suitable for tractors equipped with category 2
lower links (the diameter of the machine attachment pin is
28 mm)
The length of the mounting links can be adjusted by the
holes in the links. The tractor mounting links and the top
link are attached in the normal way, and the mounting links
are secured in their central position by means of their
stabiliser.
TRACTOR PTO
The chipper should be started carefully due to the large masses inside the chipper. During operation, the
chipper rotational speed should be kept between 540 and 1,000 rpm. The universal drive shaft is
discussed in the UNIVERSAL DRIVE SHAFT section.
HYDRAULICS
Since the M model contains no actual feeding device, the HJ 170 M/HJ 250M does not require hydraulics
from the tractor hydraulic system. The GT model feeding device has its own closed hydraulic system. It
is powered by the chipper blade disc shaft via v-belts.
For its operation, the HJ 170 G/HJ 250G/HJ261G requires hydraulics from the tractor with a single
control valve, fitted with single pressure and return connectors.
The required hydraulic system output is approx. five to twenty l/min depending on the blade
setting selected, and the minimum pressure is 140 bar
INSTALLATION OF THE ELECTRICAL SYSTEM HJ250/HJ261 (accessory/loader infeed)
Install the remote control box in a suitable place inside the tractor cabin and the 15-pin socket in a suitable
place on the rear wall outside the cabin. Connect the remote control box to the tractor's electrical system
with a 12V plug.
Connect the 15-pin plug from the chipper to the socket. The chipper's electrical system is now in working order.
This can be tested e.g. by adjusting the spout discharge direction flap.

UNIVERSAL DRIVE SHAFT
UNIVERSAL DRIVE SHAFT TYPE HJ 170
Implementation
The universal drive shaft should have the capacity to transmit power at a rate of 50 kW at a nominal
speed of 540 rpm and to sustain a torque of 900 Nm. The shaft should be fitted with an overrunning
clutch and an overload clutch.
Suitable drive shaft types include e.g. EG 50 051 CE112 Rf2.
UNIVERSAL DRIVE SHAFT TYPE HJ 250/HJ261
Implementation
The universal drive shaft should have the capacity to transmit power at a rate of 67 kW at a nominal
speed of 540 rpm and to sustain a torque of 1 900 Nm. The shaft should be fitted with an overrunning
clutch and an overload clutch.
Suitable drive shaft types include e.g. the Walterscheid W2400 SD25-610-FK96/4 195kpm/II.
UNIVERSAL DRIVE SHAFT LENGTH
The drive shaft must be of correct length for operator safety, for the resistance of the shaft itself and its
operation. The drive shaft tubes must overlap by at least 100 mm (10 cm). If the shaft is too long, it will
bottom out, leading to drive shaft breakage. With a short shaft, the tubes may be separated from each
other when the machine is lifted. This involves a significant risk of damage. Too small an overlap also
prevents the shaft from transmitting the required power without being damaged.
SHORTENING A UNIVERSAL DRIVE SHAFT
1.

4.
5.
Determine the shortest length of the shaft by lifting the machine (Figure 1).
Leave a 25 mm margin on the shaft and mark the cutting points (Figure 2).
Cut off equal pieces of all four shaft tubes (Figure 3).
Remove cutting burrs with a file and clean all tubes.
Finish by greasing the shaft tubes thoroughly.

Adjustments
10 ADJUSTMENTS
PLEASE READ THESE INSTRUCTIONS CAREFULLY AS THE CONDITION OF THE BLADES
AND THEIR CORRECT ADJUSTMENT ARE CRITICAL TO THE OPERATION OF THE
CHIPPER.
10.1 BLADE SETTING ADJUSTMENT
The blade setting (A) may be adjusted within the range of 3 to 15 mm. The smaller the blade setting,
the smaller the chips the chipper produces. On the other hand, the blade setting affects the wood
intake speed: a larger knife setting results in a faster and better wood intake.
Adjustment:
1.
Loosen the blade retaining screws (3 pcs/blade) and the blade locking screws (2 pcs/blade).
2.
Open the counter blade retaining screws and pull the counter blade out towards the feed chute.
3.
Move one cutting blade to a desired distance from the blade disc. Tighten both the retaining and
locking screws of the blade in question.
4.
Move the counter blades to a distance of 1 mm from the cutting blade. Then secure the counter
blades.
5.
Proceed to adjust the remaining three cutting blades with the aid of the counter blade, leaving a
1 mm clearance in each cutting blade.
6.
Finally, tighten all blade and counter blade retaining screws (200 Nm). Rotate the disc by hand to
ensure that the cutting blades do not touch the counter blades and that the blade clearance (B)
Is correct (1 mm) and identical for each cutting blade.
7.
Tighten the cutting blade locking screws to 30 Nm against the rear edge of the blades.

Adjustments
10.2 FEEDING DEVICE SPEED ADJUSTMENT
The rotational speed of the feed rollers in G/GT models chippers must be synchronised with the cutting
speed of the blades. If the feed roller rotational speed is too high in relation to the blade cutting speed,
the feed rollers will dig into the stems that are fed in the machine. If the feed roller speed is too low in
relation to the blade cutting speed, the feed becomes jerky.
The adjustment is started with a low feed roller rotational speed. At this stage, the cutting blades tend
to pull wood out between the feeding machine rollers. The feeding device rotational speed is then slowly
increased, until it is synchronised with the cutting blade setting of the disc.
ADJUSTMENT
To adjust the feeding device speed, turn the adjusting wheel against the bottom. When wood is fed into
the chipper, any variation between the speed of the feeding device and the blade disc can be observed.
Then adjust by turning the adjusting wheel towards the fast end of the range. Repeat the adjustment
where necessary.
G/GT
ADJUSTING WHEELS
11 OPERATION
The material to be chipped should be pre-treated where necessary. Large tree branches, roots and
boughs should be removed to fit the wood into the feeding orifice. It is recommended that the wood be
placed near the chipper to avoid carrying it long distances. In this case, the work can be done as
efficiently as possible, and the continuous flow of material will produce chips of the best quality.

READ THE SAFETY INSTRUCTIONS
MAINTENANCE AND REPAIRS
1.
2.
Always ensure that the PTO is disengaged and that the engine is stopped
before carrying out cleaning, lubrication, assembly or adjustment work.
Remove the ignition key to prevent the tractor or the machinery from
starting up accidentally.
Secure the machine appropriately before carrying out maintenance work.
12.1 SHARPENING THE CUTTING BLADES
The cutting angle (C) of cutting blades delivered from the factory is 30.5 degrees. Blades should always
be sharpened to this angle. A smaller sharpening angle will result in chipped blades, whereas a larger
angle will reduce the blade clearance angle, reducing in turn the blades' ability to draw in the wood.
Please note that the cutting blades must not heat up during the sharpening process as the heat will
cause the blades to lose their hardness. This is why the blades should be sharpened by grinding. Care
should also be taken to sharpen all blades equally to ensure the balance of the blade disc.
Counter blades generally require no sharpening. Counter blades may, however, be rounded off if
substances harder than wood (nails, sand etc.) enter the chipper. In this case, counter blades may be
straightened by grinding e.g. with a bobbing machine. However, counter blades generally require no
maintenance.

THE SAFETY INSTRUCTIONS
Withdrawing the product from service is the responsibility of the product's end user or the person or
company who owns the product at the time the decision has to be made. The disposal of the machine
and the management of the various resulting waste materials are governed in all countries by national
laws, instructions and regulations which are to be complied with. Most chipper components are made of
non-biodegradable materials. This is why the chipper should be disassembled and the materials should
be disposed of according to national regulations.
Steel and other metallic parts will be recycled via scrap yards or stripping yards.
Waste oil, plastic and rubber components (other than tyres) will be disposed of as hazardous
waste by recycling, taking them to a landfill or by other means compliant with national regulations.
Where necessary, environmental authorities will provide further information on the disassembly process
and on waste management.
