1 General information
1.1 INTRODUCTION
The purpose of this manual is to ensure that the machine is used in the manner intended by the manufac-
turer, taking safety into consideration. Everyone operating the machine or working in close proximity to it
must study this manual carefully.
Operators of the machine are expected to have basic skills in tractor handling, such as utilising the cardan
shaft drive and the tractor's lifting equipment. Before commencing work, operators must also familiarise
themselves with the machine's control and safety equipment, and ensure their proper operation.
Additional information on Maaselän Kone Oy's products is available on our website at
www.maaselankone.fi.
Keep this manual in the immediate vicinity of the machine.
1.2 PURPOSE OF USE
The Hakki Pilke Raven firewood processor is designed for the preparation of firewood from pruned wood or
logs. The firewood processor must not be used to process any treated wood, such as is found in construc-
tion waste, for example. Sand, nails or other impurities in the wood may damage the machine.
The maximum diameter of the logs to be processed is 30 cm. This limit must not be exceeded. When esti-
mating the diameter of the log you are about to cut, note that the shape of the log and other factors, such
as branches and burrs, make the actual diameter larger, and may prevent the log from being fed to the
machine. Do not split logs that exceed 50 cm in length.

2.4 CONNECTING THE MACHINE TO A POWER SOURCE
Tractor-powered model
A tractor-powered firewood processor
is connected to the tractor’s three-
point lifting device and cardan shaft.
Connecting the cardan shaft is a task
for only one person. When connecting
the machine to the tractor, there must
be no one in the tractor cabin, so as to
prevent any accidental contact with the
controls. Check all the connecting de-
vices of the tractor and the firewood
processor before connecting them.
Never use faulty equipment.
Figure 9.
When using the cardan shaft, observe any instructions provided by the manufacturer of the shaft. The ma-
chine requires 5.5 kW of power, which must be taken into account with regard to the capacity of the car-
dan shaft. A suitable cardan shaft is of power class four. Make sure that the connected shaft is locked to the
splined shaft of the multiplier gear. Connect the chain that prevents the turning motion of the guard to
hole B (Figure 9). Hang the cardan shaft from hook A (Figure 9) when the machine is not being operated
and it is disconnected from the tractor. Finally, ensure that all connections are safe and secure. Never use a
damaged or unprotected cardan shaft.
Note! Tractor-powered machines must be attached to the lifting equipment of the tractor.

HAKKI PILKE RAVEN TRANSLATION VERSION 1-2015
Electrically powered model
An electrically powered machine func-
tions with a power of 5.5 kW. The IP
rating of the electric motor is 55. The
fuse must be of at least 16 A. The elec-
trical cable must be at least 5 x 4 mm²,
and it is connected to the socket in
Figure 10.
The firewood processor can be activat-
ed with the green starter button on the
front section of the machine. Use the
red button to turn off the machine.
If the electric motor rotates in the
wrong direction (i.e. the machine
makes an abnormal noise and the hy-
draulic functions are inoperable), the
current phase is incorrect.
We recommend using an extension
cord that allows you to switch the cur-
rent phase, or an adapter.
Note! If the extension cord does not
have a phase switch, the electrical
work related to changing the phase
must only be performed by an electri-
cian.
Note! Only connect the machine to a
fault current protected socket.

HAKKI PILKE RAVEN TRANSLATION VERSION 1-2015
2.5 LIFTING AND MOVING THE MACHINE
When moving the machine, make sure that the moving and lifting capacity of your tractor or fork-
lift is sufficient for the weight of the machine (approx. 600 kg). Only lift the machine by the indi-
cated lifting points or with the lifting equipment of the tractor.
Figure 12. Lifting points of the machine
When connecting the machine to the tractor's lifting equipment, there must be no one in the tractor cabin,
so as to prevent any accidental contact with the controls. Check all the connecting devices of the tractor
and the firewood processor before connecting them. Never use faulty equipment. The pins that are used
to connect the pushbars and drawbars to the machine must be of the correct size, and the appropriate
locking pins must be used to secure them.
The machine must be placed in the transport position whenever it is moved. Exercise extreme caution
when moving the machine in the operating position. Always lower the machine to the ground when you
stop.
Note! Incorrect lifting may cause a hazardous situation or damage the machine.

HAKKI PILKE RAVEN TRANSLATION VERSION 1-2015
2.6 ADDITIONAL HYDRAULICS CONNECTIONS (ACCESSORIES)
2.7 IN-FEED CONVEYOR BELT SPEED CONTROL (ACCESSORY)
The control valve in Figure 13 adjusts the in-feed conveyor belt speed to correspond with the speed of the
splitting cycle. Rotating the valve adjustment screw clockwise slows down the speed of the in-feed convey-
or belt in relation to the splitting cycle and vice versa.
The control valve is only needed when the machine is equipped with a larger splitting cylinder (6 t), which
makes the speed of the in-feed conveyor belt faster than that of the splitting cycle. The control valve makes
sure that the end of the log meets the measuring device at the desired point of the splitting cycle.

HAKKI PILKE RAVEN TRANSLATION VERSION 1-2015
Before the actual operation of the machine, a test run and functional test must be carried out. Both the
test run and testing can only be performed by a person who has studied the machine’s manual.
Before the test run, all of the components of the firewood processor must be checked. If any faults or wear
and tear that may affect the safe use of the machine are discovered, the processor must not be used until
the faulty or worn component is replaced and safe use can be ensured.
Before using the machine, the operator must ensure that
the machine has not sustained any damage
the machine’s operating environment is in accordance with Section 1.4
the machine is positioned on a solid foundation
no unauthorised persons are within the machine’s danger zone
all guards and safety devices are in place and functional
opening the splitting and cutting guard stops the machine’s hazardous functions (see items 11, 12
and 15 in Section 3.3)
the hydraulic hoses and pipes are undamaged. The pipes must be replaced if there is a tear in the
hoses or pipes, if they leak, or if the surface layer of the hydraulic hose has worn all the way down
to the supporting weave.
the machine does not leak oil
the machine functions properly (Section 3.3).
Note! Do not use the machine if the requirements listed above are not met!
3.2 PERFORMING A TEST RUN ON THE MACHINE
1. Check that the guard for the firewood processor's cutting and splitting section is down.
2. Check that the input and output conveyors are in the operating position.
3. Ensure that the splitting groove is empty.
4. Make sure that you are familiar with the functions of the machine's controls. If necessary, refer to
Section 3.1.
5. Activation:
-Tractor drive: Start the tractor and connect the output, starting with a slow speed and increas-
ing the speed to a maximum of 410 rpm.
-Electrical drive: Connect the cable to the socket of the firewood processor, start the machine
by pressing the start button and wait a moment. This will activate the electric motor at full
speed.
6. Start the splitting motion by pushing up lever C. The splitting beam must move forward by pushing
the lever up, and must stop immediately when the lever is returned to the initial position. The split-
ting beam must move backwards by pulling the lever down, and must stop immediately when the
lever is returned to the initial position.
7. Do the following to ensure that the saw chain lubrication functions automatically: (If necessary, see
Section 4.10).
a. Use lever C (Figure 15) to perform a few sawing motions without any actual logs.
b. Turn off the machine and disconnect it from the power source.
c. Open the guard and see if the saw chain has been supplied with oil.
8. Ensure that the saw chain starts running when you lower the saw bar by about 2 cm using lever C
(Figure 15).

HAKKI PILKE RAVEN TRANSLATION VERSION 1-2015
Note! In cold weather, the saw valve shaft may be sluggish at first, which means that the saw bar must
be driven to the bottom position a couple of times for the saw chain to run.
9. Move the splitting beam forward and stop it by opening the cradle guard of the cutting and split-
ting section.
10. Ensure that the splitting beam moves backwards by pulling down lever C (Figure 15).
11. Test run the feed motion of the input conveyor by pushing lever A (Figure 15) to the right.
12. Visually check that the output conveyor runs at normal speed.
13. Ensure that the splitting motion or saw chain cannot be activated with the guard open.
If a fault occurs during the test run, determine the cause of the fault and take remedial action as deemed
necessary. The machine must be shut down and disconnected from the power source for the duration of
both the diagnostics and repairs.
Note! Do not leave a running machine unsupervised!
3.3 WOOD FEEDING, CUTTING AND SPLITTING
The input conveyor belt or feed roller feeds the wood to be processed into the machine. Feed wood into
the machine using control lever C (Figure 15 in Section 3.1).
When feeding wood into the machine, make sure that it does not present a risk of your clothes, hands or
other parts getting caught in the machine, such as due to the shape of the log. Do not use your hand to
guide the log into the cutting section. Adjust the measuring device to the desired measurement.
1. Choose the log to process. Note that the maximum log diameter is 30 cm. The knottiness and shape
of the log can increase the diameter.
2. Use the input conveyor to feed wood into the cutting section by pushing up lever C (Figure 15 in
Section 3.1). The input conveyor belt can also be driven forward by pushing lever A (Figure 15) to
the right, especially when the log is further away from the cutting section and a longer and con-
tinuous feed motion is required.
3. Once the log stops for cutting in the mechanical measuring device, lock the log in place with the
wood gripper by pressing down handle B (Figure 15).
4. Cut the log by pulling down lever C (Figure 15), which activates the saw chain and lowers the saw
bar. Simultaneously, the splitting beam returns to its initial position.
5. Return the saw bar to the upper position by pushing up lever C (Figure 15). This moves the splitting
beam forwards and splits the log. Simultaneously, the input conveyor pushes the log forwards for
the next cut.
Note! Only move the splitting beam forward for the required length. For example, if you have ad-
justed the machine for logs of 35 cm in length, the splitting beam needs to move only approx. 37
cm. This notably increases the efficiency of the machine.

HAKKI PILKE RAVEN TRANSLATION VERSION 1-2015
Re-splitting or splitting without cutting
Raise the guard of the cutting and splitting section.
Place the log you want to split in the splitting groove.
Close the guard of the cutting and splitting section.
Move the splitting beam forwards for the desired length by pushing up lever C and return
the splitting beam backwards by pulling down lever C.
The above procedure can be used to split wood without cutting it.
Placing logs on the input table
We recommend the use of auxiliary devices, such as the HakkiFeed 371 timber deck. If a timber deck is not
attached to the machine, the maximum allowed length is 4.5 m. Always lift and place wood on the input
table in a safe manner that does not endanger the operator.
Note! Placing logs directly on the input table with a loader is strictly prohibited.
Note! Ensure that the log's centre of gravity stays on the conveyor.
Sawing the last log
When sawing wood, the second to last piece should be sawn in such a way that the remaining piece is of a
sufficient length. This ensures that the log will stay firmly under the wood gripper and that the sawing will
be steady and safe.
3.4 USING THE OUTPUT CONVEYOR
The Hakki Pilke Raven firewood processor’s output conveyor belt is driven by a hydraulic motor.
The output conveyor can be adjusted laterally and vertically. The following describes how the conveyor can
be turned laterally (accessory) by using turning lever A and handle B (Figure 16):
Release the lock of the conveyor by pushing lever A (Figure 16) towards the conveyor, and turn the convey-
or to the desired position with handle B.
The maximum operating angle for the output conveyor is 40°. The maximum angle is indicated on the label
(Figure 17) and the instructions attached to the output conveyor.
