1 General information
INTRODUCTION1.1
The purpose of this manual is to ensure that the machine is used in the manner intended by the manufacturer,
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.hakkipilke.fi.
Keep this manual in the immediate vicinity of the machine.
PURPOSE OF USE1.2
The Hakki Pilke Raven 33 firewood processor is designed for preparing firewood from pruned wood or logs. The
firewood processor must not be used to process any treated wood, such as is found in construction waste. Sand,
nails or other impurities in the wood may damage the machine.
The maximum diameter of the logs to be processed is 33 cm. This limit must not be exceeded. When estimating
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. The machine
is intended to be used mainly for logs less than 30 cm in diameter. However, logs with a diameter of up to 33 cm
can be split temporarily by lowering the splitting blade to the lower position. Do not split logs that exceed 50 cm
in length.

CONNECTING THE MACHINE TO A POWER SOURCE2.4
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 that are provided by the manufacturer of the shaft. The
machine requires 7.5 kW of power, which must be taken into account with regard to the capacity of the cardan
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. Ensure the correct length of the cardan shaft –consider the lifting and lowering of the
machine. 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. Fi-
nally, 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 33 TRANSLATION VERSION 1
Electrically powered model
An electrically powered machine func-
tions with a power of 7.5 kW. The IP
value of the electric motor is 55. The
fuse must be a min. 20 A type C fuse.
The electrical cable must be at least 5 x
4 mm², and it is connected to the sock-
et in Figure 10. The recommended max-
imum length for the supply cable is 30
metres.
The firewood processor can be activat-
ed with the green remote starter but-
ton on the front section of the machine
(Figure 11). Use the red remote starter
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! The actual starter is located be-
hind the machine (Figure 10). If the
machine’s thermal relay is triggered,
remove the fault and reset the relay by
pressing the Stop button on the starter
behind the machine.
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.

LIFTING AND MOVING THE MACHINE2.5
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. 750 kg without accessories). Only lift the
machine by the indicated 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 fire-
wood 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 mov-
ing 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.

Using hydraulic in-feed rollers and HakkiFeed log deck quick couplings
Hydraulic in-feed rollers and HakkiFeed log decks can be connected in series with the machine’s in-feed conveyor.
In this case, the in-feed rollers function automatically in synchronisation with the in-feed conveyor.
Connect the in-feed roller hoses to quick couplings C (red) and D (black).
Turn the cock in Figure 13 down to open it and enable the oil to flow into quick couplings C and D in Figure 13.
Make sure that the rotation direction of the rollers is the same as the conveyor’s direction. If necessary, switch
the order of the hoses in quick couplings C and D.
Note! Cock A must always be turned off (to the right) whenever quick couplings C and D are not in use.
Note! Only connect official Hakki Pilke accessories to the machine’s quick couplings!

Figure 15
Names and functions of the controls in Figure 15:
A. In-feed conveyor control lever
Turning the lever to the right runs the in-feed conveyor belt forward, and vice versa.
B. Log press control lever
C. Saw, splitting and in-feed conveyor control lever
The splitting beam moves forward by pushing the lever up. This also moves the in-feed conveyor for-
ward.
The splitting beam moves backwards by pulling the lever down. This also rotates the saw chain.
D. Height adjustment of the splitting blade.
E. Out-feed conveyor locking lever
The swivel out-feed conveyor can be locked to the desired position using the lever
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 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

19
HAKKI PILKE RAVEN 33 TRANSLATION VERSION 1
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 sup-
porting 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!
PERFORMING A TEST RUN ON THE MACHINE3.2
1. Check that the guard for the firewood processor's cutting and splitting section is down.
2. Check that the in-feed and out-feed 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 increasing 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 splitting beam
must move backwards when pulling the lever down, and it must stop immediately when the lever is re-
turned to the initial position.
7. Do the following to ensure that the saw chain lubrication functions automatically: (If necessary, see Sec-
tion 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).
Note! In cold weather, the saw valve shaft may be sluggish at first, which means that the saw bar must be driv-
en 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 splitting sec-
tion.
10. Ensure that the splitting beam moves backwards by pulling down lever C (Figure 15).
11. Test run the feed motion of the in-feed conveyor by pushing lever A (Figure 15) or lever F (Figure 16) to
the right.
12. Visually check that the out-feed conveyor runs at normal speed.
13. Ensure that the splitting motion or saw chain cannot be activated with the guard open.

20
HAKKI PILKE RAVEN 33 TRANSLATION VERSION 1
If a fault occurs during the test run, determine the cause of the fault and take remedial action as deemed neces-
sary. The machine must be shut down and disconnected from the power source for the duration of both the diag-
nostics and repairs.
Note! Do not leave a running machine unsupervised!
WOOD FEEDING, CUTTING AND SPLITTING3.3
The in-feed 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). Lever A can be used to perform a long feed motion.
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, due to the shape of the log, for example. 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 33 cm. The knottiness and shape of
the log can increase the diameter.
2. Use the in-feed conveyor to feed wood into the cutting section by pushing up lever C (Figure 15 in Section
3.1). The in-feed 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 continuous feed mo-
tion is required.
3. Once the log stops for cutting in the mechanical measuring device, lock the log in place with the log press
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 in-feed conveyor pushes the log forwards for the next
cut.
Note! You should only move the splitting beam forward for the required length. For example, if you
have adjusted the machine for logs of 35 cm in length, the splitting beam needs to move only approx.
37 cm. This greatly increases the machine’s output.
Note! The saw should not be forcefully pressed into the wood. Instead, let the saw chain bite into the
wood on its own. This will also significantly extend the service life of the saw bar and chain.
