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 38 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 38 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 channel is designed for logs up to 60 cm in length, which should never be exceeded.

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 combi 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.
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
13 / 40
Hakki Pilke 38 Pro Translation Version 3
faulty equipment.
Connect the power cable for the electric
controls (in Figure 14) to the 12 V, 3-pin
socket for a work machine.
Figure 12.
When using the cardan shaft, observe any instructions provided by the manufacturer of the shaft. The
machine requires 25 hp 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. Check that the shaft is properly locked to the splined shaft
of the angle transmission. Connect the chain that prevents the turning motion of the guard to hole B. 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.
3.2.2. Electrical drive
An electric-powered machine
is powered by a 10 kW
electric motor. The IP value
of the electric motor is 55.
The fuse must be at least
25 A. The electrical cable
must be at least 5 x 4 mm²,
recommended maximum
length is 30 m. In order to
connect the cable at the
combi machine, move
protective cover B of socket
A and the angle gear and
secure it into a position
where it covers the multiplier
gear, as in Figure 13.
In an electrically-powered
machine, the power cable of
the electric control is
connected to the socket on
the side of the machine.
Figure 13. The machine’s electrical drive
14 / 40
Hakki Pilke 38 Pro Translation Version 3
The machine is activated
using the green button of the
remote starter on the control
panel on the front panel 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. We
recommend using an
extension cord that allows
you to switch the current
phase using a phase switch 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 electrician.

3.2.3. Adjusting the log length
The Hakki Pilke 38 Pro is equipped with a mechanical log measurement device with an incremented
adjustment value of 22–60 cm.
1. Turn the machine off and open the
machine’s guard.
2. When the wood limiter is in the
splitting position, set it to the
desired length by removing cotter
pin B in the limiter's locking pin
and by pulling out locking pin A.
Lock limiter plate C in the desired
position. Re-insert locking pin A
and cotter pin B.
Note! Turn the limiter plate to the
correct position according to the
thickness of the log. (See Figures 17
and 18). The wrong position may
cause damage to the machine!

3.2.4. Using the out-feed conveyor
The Hakki Pilke 38 Pro firewood processor’s out-feed conveyor belt is driven by a hydraulic motor. To change
the speed of the belt, use adjuster B (Figure 10). The following describes how the conveyor can be turned
laterally by using turning lever A and handle B:
16 / 40
Hakki Pilke 38 Pro Translation Version 3
Figure 19.
Release the lock of the conveyor by pushing lever A towards the conveyor, and turn the conveyor to the
desired position with handle B.
If hydraulic turning of the conveyor (optional) is available, you can use control lever D (Figure 10) to swivel the
conveyer laterally. In other words, turning the lever forwards swivels the conveyer to the left, and turning
the lever backwards swivels the conveyer to the right.
The maximum operating angle for the out-feed conveyor is 40°. The maximum angle is indicated on the label
below and in the instructions attached to the out-feed conveyor.
17 / 40
Hakki Pilke 38 Pro Translation Version 3
3.2.5. Splitting blade adjustment
The machine’s splitting blade is controlled hydraulically with joystick E (Figure 10) (forwards => blade is
lowered, backwards => blade is raised). 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 removal device
A hydraulic dust collector is available as an accessory for the splitter. It allows you to collect sawdust for other
purposes. The sawdust removal device is on when the control valve is open, as in Figure 19b.
Figure 19b
4. Operating the machine
4.1. Performing a test run on the machine
The machine may not be used before a test run has been performed and all the functions of the machine have
been tested. 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.
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, see Section
3.2.
5. Activation.
6. Tractor drive: Insert the connector for the electric control device into the tractor's electrical socket.
Start the tractor and connect the power take-off, starting with a slow speed and increasing the speed to
a maximum of 500 rpm.
18 / 40
Hakki Pilke 38 Pro Translation Version 3
7. Electrical drive: Connect the cable to the socket of the firewood processor, start the machine by
pressing the start button and wait until the electric motor operates at full speed.
8. Start the splitting motion by pressing joystick button A (Figure 11). The splitting motion must be
normal.
9. Do the following to ensure that the saw chain lubrication functions automatically: (If necessary, see
Section 7.0.)
a. Perform a few sawing cycles without wood by pressing joystick button B (Figure 11).
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.
10. Start the splitting cycle and stop it by opening the cradle guard of the cutting and splitting section.
11. Conduct a test run for the in-feed conveyor's feed and reverse motion with joystick E (Figure 10).
12. Activate the out-feed conveyor using lever A (Figure 10) and adjust the conveyor speed to an
appropriate level using control B (Figure 10). Also ensure that lever A stops and reverses the conveyor.
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.
4.2. Placing logs on the in-feed conveyor
We recommend the use of auxiliary devices, such as the HakkiFeed 422 timber deck. If a timber deck is not
attached to the machine, the maximum allowed log length is 4.5 m. Always lift and place wood on the in-feed
conveyor in a safe manner that does not put the operator in danger.
Note! Placing logs directly on the in-feed conveyor with a loader is strictly prohibited.
Note! Ensure that the log's centre of gravity stays on the conveyor.
4.3. Feeding and sawing wood
The in-feed conveyor feeds the wood into the firewood processor. Turn joystick E (Figure 10) to the right to
feed wood into the machine. The feed can be reversed by turning the joystick to the left.
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 wood measuring device to the desired length and make sure
that the speed of the out-feed conveyor belt is suitable by adjusting it.
1. Choose the log to process. Note that the maximum log diameter is 38 cm. The knottiness and shape of
the log can increase the diameter.
2. Use joystick E to feed the log into the machine with the in-feed conveyor. Turn the lever to the right
to activate the feed.
3. When the log stops at the mechanic measuring device for cutting, hold the log in place by placing
more pressure on wood gripper lever C (Figure 10).
4. Cut the log by pressing joystick push button B (Figure 11). This activates the HakkiCut™ function: the
saw chain starts rotating, the saw chain oil pump performs a pumping cycle and the saw bar moves
down at optimal power.
5. Return the saw bar to the upper position by releasing button B (Figure 11). This also stops the saw
chain.
19 / 40
Hakki Pilke 38 Pro Translation Version 3
4.3.1. Jamming of the cutting blade
If the cutting blade gets jammed in the log, stop sawing and try again on another section of the log. If the cut
is misaligned because the bar drags to one side, the degree of sharpness of the saw chain must be checked. A
chain that is not evenly sharp will always drag towards the blunter side, which will make cutting a thick log
impossible. Also check that the bar is not worn or crooked. On the other hand, sawing with an evenly dull
chain is inefficient, and the sawing chain must be sharpened or replaced (see Sections 5.1.1 and 5.1.2).
4.3.2. 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. Drive the last log directly into the splitting section, and start the splitting process using
joystick button A (Figure 11).
4.3.3. Using the quick couplings of the additional hydraulics
Connect the additional hydraulics (e.g. when using the HakkiFeed 381 log lifter) by pushing the auxiliary
device’s hydraulic hoses into quick couplings A and B in Figure 20 (in Section 4.3.4). The hose with red marking
goes to higher quick coupling (also marked with red colour).
4.3.4. Using the quick couplings of the auxiliary feed rollers
The auxiliary feed rollers can be connected in series with the in-feed conveyor. This way, the rollers are
automatically synchronised to operate with the input conveyor when feeding logs using joystick E (Figure 10).
1. Connect the auxiliary feed roller
hoses to quick couplings C and D,
hose with red marking to higher
quick coupling
2. Remove the guard as instructed in
the instructions of point 2 of
Section 4.4.4.
3. Open cock E (Figure 21) to allow oil
to flow to the quick couplings
(Figure 20) C and D.
4. Make sure that the rotation
direction of the rollers is the same
as the conveyor’s direction. If
necessary, change the connections.
Figure 20.
C
D B A
20 / 40
Hakki Pilke 38 Pro Translation Version 3
Note! Cock E must always be
turned off (as in Figure 21)
whenever quick couplings C and D
(Figure 20) are not in use!
Figure 21.
4.4. Log splitting
The splitting slide of the machine performs a splitting cycle every time button A on the control lever E (Figure
11) is pressed. The splitting function is not available when the machine’s cover is open. The splitting cycle can
be stopped and reversed by opening and closing the machine’s cover.
4.4.1. Jamming of wood on the splitting blade
If a piece of wood gets jammed on the splitting blade in a situation where the splitting force is insufficient to
push the piece past the blade despite several attempts to do so, do the following:
1. Return the splitting beam to the initial position by opening and closing the machine’s protective
cover.
2. Lift the splitting blade to the highest possible position with lever E (in Figure 10) and activate the
splitting.
3. If necessary, cut a sufficiently thick piece of wood (approx. 20–25 cm) into the splitting channel and
activate the splitting cycle. The new piece will then push the jammed piece past the blade.
4. Lower the blade by approx. 10 cm and repeat step 3. Repeat step 4 until the jammed log has passed
the blade, piece by piece.
4.4.2. Resplitting or splitting without cutting
1. Raise the protective cover of the cutting and splitting channel.
2. Place the log you want to split in the splitting channel.
3. Close the protective cover of the cutting and splitting channel.
4. Activate the splitting cycle with button A (Figure 11).
The above procedure can be used to split wood without cutting it, as necessary.

1. Pull out locking bar A, as shown in
Figure 22. Lower the splitting blade
to its low position, which releases
shaft C from blade slot B.
2. Shut down the machine and
disconnect it from its power source.
3. Open the guard and lift the splitting
blade out of its slot.
4. Install a new splitting blade by
reversing the above steps.

4.4.4. Adjusting the stroke length of the splitting motion
In the Hakki Pilke 38 Pro log splitter, the
splitting cylinder is controlled electrically
by sensors A and C in Figures 24 and 25.
The stroke length of the splitting
cylinder can be adjusted as follows:
1. Shut down the machine and
disconnect it from its power
sources.
2. Remove the cover plate shown in
Figure 23. Note! The fastening
bolts (5 pcs) do not have to be
removed completely. Simply
loosen the bolts and slide the
cover plate so that the bolt heads
fit through the hole.
3. Sensor A is used to determine
the point at which the splitting
cylinder will stop during the
reversal motion. If necessary, the
position of the sensor can be
changed with tightening nut B.
4. Sensor C is used to determine the
point at which the splitting
cylinder changes direction during
the splitting motion, in other
words, how close to the splitting
beam will the splitting blade go.
If necessary, the position of the
sensor can be changed with
tightening nut D.
Note! The covers and guards must be
reattached after maintenance.

4.5. Using the out-feed conveyor
The out-feed conveyor can be controlled horizontally and vertically. The safety zone for the out-feed conveyor
is 10 metres. When operating the machine, the maximum permitted angle of the out-feed conveyor is 40°.
The running speed of the out-feed conveyor can be freely adjusted with adjustment screw B (Figure 10). The
standard equipment of the splitter includes an out-feed conveyor reverse valve that allows a jammed log to
be easily removed from between the conveyor belt and separation plate C, by reversing the conveyor belt a
short distance. You can also stop the belt completely by setting the conveyor control valve A (in Figure 10) to
its middle position.
The tension (and alignment) of the output conveyor’s belt is adjusted with nuts A (2 pcs) by loosening the
adjustment nut on the side to which you wish the belt to run.
The out-feed conveyor is equipped with an
automatic debris removal device. It separates
debris and sawdust from the processed
firewood.
The following factors significantly affect the
operation of the debris removal device: the
angle of the out-feed conveyor, the speed of
the belt and the distance and height of
separation plate C from the upper roller of the
conveyor. In other words, the debris
separation result is better the steeper the
angle (however, no more than 40 degrees),
the lower the speed and the longer the
distance between separation plate C and the
upper roller. The distance of separation plate
C is optimised at the factory in conjunction
with the testing of the machine. However, the
adjustment can be changed, if necessary.
The optimal speed for the belt can be
determined by trying different settings. The
split logs should only just pass over the plate.
The separation plate can be adjusted in the
longitudinal direction using adjustment screws
B (in Figure 26), and in vertical direction using
the bolts at the end of the separation plate.
If necessary, separation plate C can also be
disabled (when using the Hakki Pilke Cleaner
cleaning drum, for example) as follows:
1. Detach one end of spring A (in Figure
26a, 2 pcs) from separation plate C.
2. Turn plate C to the lower position, as
shown in Figure 26a.
3. Lock it in the lower position using latch
Figure 26.
Figure 26a

Hakki Pilke 38 Pro Translation Version 3
B (in Figure 26a).
Note! The operator must ensure that the distance between the debris discharge opening and the pile of
debris that accumulates under it is at least 20 cm.
4.6. After use
1. After you have finished making firewood, stop the out-feed conveyor, shut down the machine and
remove the firewood from the splitting channel and conveyor.
2. Check that the machine has not been damaged.
3. Place the out-feed conveyor into a position that allows the conveyor and firewood processor to be
moved safely off the processed firewood.
4. Clean the machine.
If you will not be using the firewood processor for a while, do the following:
5. As necessary, use your tractor's hydraulics or a forklift to hoist the firewood processor and carefully
move it to a location where you can place the in-feed and out-feed conveyors as well as the working
platform into their transport and storage positions.
6. Place the conveyors into the transport and storage position.
7. Clean the machine and carry out any maintenance.
8. Store the machine according to the instructions in Section 6.
5. Machine maintenance
The machine must be disconnected from its power source before any maintenance, adjustment, replacement
or cleaning measures. Only use spare parts that are supplied by the manufacturer or your retailer. If any
guards of the machine have to be removed for maintenance, they must always be reattached before the
machine is activated. After maintenance and adjustment measures, a test run must be carried out on the
machine, according to the instructions in Section 4.1.
5.1. Cutting blade and drive end
If the cutting blade of the machine does not penetrate the wood properly, cuts it too slowly or the cut is
skewed, the saw chain is most likely blunt. It is a good idea to keep a replacement chain on hand, so that you
do not need to interrupt your work to sharpen the chain.

Hakki Pilke 38 Pro Translation Version 3
5.1.1. Replacing and tensioning the saw chain
The standard equipment of the Hakki Pilke 38 Pro firewood processor includes an AC10 automatic chain
tensioner. Using a pressure spring, the AC10 maintains optimal saw chain tension at all times (the spring load
pushes the saw motor backwards at an optimal power).
Replace the saw chain as follows:
1. Turn off the machine and disconnect it from its
power source.
2. Open the guard.
3. Lower the saw bar about halfway down, as in
Figure 27. Note! Use gloves!
4. Using a 17 mm wrench, turn locking part A (in
Figure 27) about 90 degrees in the open direction
to release the saw chain locking mechanism.
5. Pull the saw chain down to move the saw motor
forwards and to loosen the chain, as shown in
Figure 27a.
6. First release the saw chain from the drive pulley,
then from the bar, then remove the chain.
7. Install the new cutting chain (first on the drive
pulley, then on the bar) and ensure that the
cutting teeth face the rotating direction.
8. Also ensure that the chain is properly placed on
the groove of the bar, and then tighten the chain
by turning locking part A (in Figure 27) about
90 degrees to the close direction using a 17 mm
wrench.
9. Finally, ensure that the chain is at the correct
tension and properly in place.

Hakki Pilke 38 Pro Translation Version 3
10. Fine-tune the tension of the saw chain by
loosening bolts A (Figure 27b) and turning
adjustment screw B in the open or close direction
to loosen or tension the chain. A new chain might
stretch considerably during first hours of use.. In
this case, you may have to tension the chain
manually.
Figure 27b.
5.1.2. Replacing the saw bar
Replace the saw bar as follows:
1. Remove the saw chain according to steps 1–6
in Section 5.1.1.
2. Remove the bar bolts (2 pcs) and remove

Figure 29.
5.3. Changing the oil
Change the hydraulic oil of the firewood
processor as follows:
Note! Select the appropriate oil type according to
the type of operation and outdoor temperature. If
the electric motor is started at sub-zero
temperatures, we recommend using an oil with ISO
VG 32 viscosity, maximum oil temperature of
60 °C. In warmer environments, we recommend a
viscosity of ISO VG 46, maximum oil temperature
of 75 °C.
1. Shut the machine down and disconnect it
from its power sources.
2. Remove the rear cover of the machine in
accordance with the instructions in steps 1–

Replace the in-feed conveyor belt as
follows:
1. Shut the machine down and
disconnect it from its power
sources.
2. Raise and lock the in-feed
conveyor into the transport
position. (See Section 3.1.1.)
3. Move the belt joint to a suitable
height.
4. Disconnect the joint by using, for
example, pliers to pull out pin A,
which holds the joint together.
5. Remove the old belt.
6. Slide the new belt under the
table from the side of the in-feed
conveyor's drive roller B until you
can pull the belt out from the
other end C.
7. Lead the rest of the belt under
the wood gripper, around the
rear roller and, finally, behind the
conveyor.
8. Connect the joint by inserting pin
A into the joint.
9. Turn the conveyor back to the
operating position and tension
the belt.
10. Finally, adjust the belt to the
correct tension and to run
straight with the help of the
adjustment nuts D.

5.4.2. Replacing and tensioning the out-feed conveyor belt
The instructions for tensioning and aligning the out-feed conveyor are presented in Section 4.5.
Replace the out-feed conveyor belt as follows:
1. Pull out the pin locking the conveyor in place and lower the conveyor to the ground.
2. Shut the machine down and disconnect it from its power sources.
3. Move the belt joint to the start of the conveyor.
4. Fold the conveyor, but do not place the belt support in the transport position. This will allow the belt
to hang loose.
5. Disconnect the joint by opening the bolts.
6. Remove the old belt.
7. First, insert the new belt under the folded conveyor (bottom opening) from the end of the conveyor
with the plates facing downwards. Feed the belt in until you can pull it out from the other end of the
conveyor. Pull out a length of approx. 60 cm.
8. Push the other end of the belt into the upper section of the folded conveyor (top opening) from the
end of the conveyor. Feed it in until you can connect the joint.
9. Pull the excess belt to the start of the conveyor.
10. Lower the conveyor back to the operating position and tension the belt.
The belt is at the correct tension when its middle section is raised approx. 15 cm when the conveyor is in

5.6. Saw chain lubrication
The saw chain is automatically lubricated
whenever it starts to rotate. The pump
pressure feeds oil from the tank to the saw
chain. Use a hexagonal key and the hole in the
frame on the left side of the saw bar to adjust
the amount of oil (see Figure 47a).
Add saw chain oil through filler cap A. Oil level
gauge B indicates the proper time to add oil.
When gauge B is light brown, the oil level is
sufficient, but when the gauge is clear, oil
must be added (see Figure 47).
Figure 47.
