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
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.
1.2.Purpose of use
The Hakki Pilke 50 Pro 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 47 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 into
the machine. The splitting groove is designed for logs up to 60 cm in length. Never cut or split logs that
exceed the maximum length.

3.2.1. Tractor drive
A tractor-powered firewood processor is
connected to the tractor’s three-point lifting
devices and cardan shaft. To connect the
machine to the cardan shaft, you have to move
protective cover A of the socket and multiplier
gear into a position where it covers the socket
(in combi models).
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
devices of the tractor and the firewood
processor before connecting them. Never use
faulty equipment.
The 3-pin power cable for the electric controls is
connected to the tractor’s 12 V socket for a
work machine (Figure 14).
Figure 12.
When using the cardan shaft, observe any instructions provided by the manufacturer of the shaft. The
machine requires 15 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. Connect the chain that prevents the turning motion of the
protective cover to slot B (2 options). Hang the cardan shaft from hook C when the machine is not being
operated and when 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.
Note! The starter (Figure 15) only functions when the machine is powered by electricity.

16 / 47
Hakki Pilke 50 Pro Translation Version 1-2018
3.2.2. Electrical drive
An electrically powered machine is
driven by a 15 kW electric motor. The IP
rating of the electric motor is 55. The
fuse must be at least a 32 A type C fuse.
The electrical cable must be at least 5 x 6
mm², and the recommended maximum
length is 25 metres. In order to connect
the cable, move protective cover B of
socket A and the multiplier gear and
secure it into a position where it covers
the multiplier gear.
In an electrically powered machine, the
power cable for the electric controls is
connected to the 3-pin socket on the
side of the machine.
The electrically powered machine is
turned on with the green button of the
remote starter, located in the control
panel in the front of the machine (Figure
15). The actual starter is located behind
the machine’s rear cover. The starter
features an automatic fuse and a thermal
relay for the electric motor. The thermal
relay can be reset by pressing the red
stop button on the starter at the rear of
the machine.
If the electric motor rotates in the wrong
direction (i.e. the machine makes an
abnormal noise and the hydraulic
functions are inoperable), the current
phase is incorrect.
You can turn the gear with switch C in
Figure 13 by rotating it 180 degrees.

3.2.3. Adjusting the log length
The Hakki Pilke 50 Pro features a hydraulic measuring device for cutting firewood, with an adjustment
value of approx. 20 to 60 cm.
When sawing, the log limiter plate (B in Figure 16) always moves approx. 5 cm backwards with the help of
a hydraulic cylinder to ensure that the log does not get stuck and falls freely into the splitting groove.
Before splitting, the operator must always ensure that the log is not oversized and does not connect with
limiter plate B.
1. Turn the machine off and open the machine’s guard.
2. Adjust the log length limiter to the desired length by releasing the lock in Figure 16 to the
open position (as shown in the smaller figure) and sliding limiter plate B to the desired
position.
3. Turn lock A in Figure 16 back to the closed position.
4. If necessary, you can fine-tune the measuring device by loosening nut C in Figure 16 and
rotating adjustment screw D to the desired direction. Tightening the screw increases log
length and vice versa. When you are finished, lock nut C back into place. (If the log length is
standard, you can fine tune the log length to minimise the amount of waste wood).
Figure 16. Log length adjustment

Hakki Pilke 50 Pro Translation Version 1-2018
3.2.4. Using the out-feed conveyor
The Hakki Pilke 50 Pro firewood processor’s out-feed conveyor belt is driven by a hydraulic motor. To
change the speed of the belt, use adjuster C in Figure 17. The conveyor angle can be changed
hydraulically in the horizontal and vertical directions by using lever D shown in Figure 17:
-Lever forwards: the conveyor turns to the left
-Lever backwards: the conveyor turns to the right
-Lever to the left: the conveyor’s angle to the ground increases
-Lever to the right: the conveyor’s angle decreases
Figure 17.
By using lever B (Figure 17), you can stop the conveyor (middle position) and, if necessary, reverse the
conveyor belt for a short distance (approx. 1 m) by pulling the lever back if a piece of wood is stuck
between the conveyor cleaning plate and the upper roller, for example.
NOTE! The maximum operating angle for the out-feed conveyor is 40°. The maximum angle is indicated
in the label below and the instructions attached to the out-feed conveyor.

19 / 47
Hakki Pilke 50 Pro Translation Version 1-2018
3.2.5. Splitting blade adjustment
The machine’s splitting blade is controlled hydraulically with control lever E (Figure 10). Pushing the lever
in the front position causes the blade to be lowered, while pulling the lever to the back position causes it
to rise. Logs should always be as centred as possible when passing the blade in order to keep the size of
the firewood consistent.
The blade can be lowered to the lowest position in one go by raising the blade to the upper position and
clearing the space under the blade. The machine must be shut down and disconnected from its power
source for the duration of the cleaning.
3.2.6. Using a sawdust blower
A hydraulic sawdust blower is available as an accessory for tractor-powered machines, while an electrical
blower is available for electrically powered and tractor-powered machines. The sawdust blower allows
you to keep the base of the machine clean and collect sawdust for other purposes.

20 / 47
Hakki Pilke 50 Pro Translation Version 1-2018
Using a hydraulic sawdust blower:
The hydraulic sawdust blower (accessory) is powered by the tractor’s hydraulics. Install the blower as
follows:
1. Attach hose A (red string) in Figure 17a
to the pressure-side quick coupling of
the tractor’s hydraulics.
2. Connect hose B (black string) to the
return-side quick coupling in the
tractor’s hydraulics.
3. Ensure that flow adjustment screw C is
in the correct position as follows.
-Loosen locking nut D.
-Fully bottom out adjustment screw C.
-Then, OPEN adjustment screw C for
exactly 1 rotation.
-Retighten locking nut D.
At these adjustments, the sawdust
blower’s rotor speed will be roughly
2,600 rpm.
Note! Excessive rotation speed
(adjustment screw C is opened by
more than one rotation) may damage
the sawdust blower!
