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.
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 HakkiFeed 422 log rack is intended for moving pruned wood or logs onto a Hakki Pilke firewood
processor. The firewood processor must not be used to process any treated wood, such as is found in
construction waste.
The maximum diameter of the logs to be processed is 40 cm. This limit must not be exceeded. The maximum
length of the logs to be placed on the rack is 4 metres, and the minimum length is 2 metres.

2. Receipt and assembly
2.1. Delivery inspection
Dispose of the packaging material in an environmentally friendly manner.
Check that the machine has not sustained any damage during transit, and ensure that all necessary parts are
included in the package. In the event of any defects or damage, contact the retailer immediately.
2.2. Assembly instructions
The rack can be delivered either assembled or packaged. If the rack is delivered in packaged form, a
sufficiently proficient person must assemble it before use in accordance with the assembly instructions.
2.3. Lifting and moving the machine
When moving the machine, make
sure that the moving and lifting
capacity of your tractor or forklift is
sufficient for the weight of the
machine. Ensure the sufficient length
of the lifting prongs so that the tips
rest safely under both frame plates
(Figure 1). Only lift the rack when it is
empty and use the lifting points
shown in Figure 1.
Figure 1. Lifting points of the machine
Note! Incorrect lifting may cause a hazardous situation or damage the machine.

2.4. Main components of the machine
The HakkiFeed 422 log rack is an accessory for the Hakki Pilke firewood processor. It is controlled hydraulically
with the operating levers of the Hakki Pilke firewood processor’s control unit.
A. In-feed conveyor
B. Log table
C. Feeder

3. Control functions and setting up the machine
3.1. Arranging the machine for operation and transport
Before arranging the machine for operation and using it, ensure that the operating conditions, detailed in
Section 1.4, are met and review the safety instructions in Section 1.5.
When preparing the rack for operation, ensure that it is positioned on an even and firm foundation so that the
logs on the rack are straight. Ensure that the rack cannot move or slide on its foundation during use. Make
sure that the machine’s hydraulic hoses cannot be caught between moving parts or cause a hazard.
When arranging the rack for transport, clear any wood off of it and fix the hydraulic hoses to it with cable ties,
for example.
Note! Inspect and clean the machine before arranging it for transport.
3.1.1. Adjustments
Adjust the height of the rack according to the firewood processor model in such a way that the rack’s in-feed
conveyor A is at least 20 mm higher than the machine’s in-feed belt. Adjust the distance between the machine
and rack to ensure the safe transfer of logs to the machine. The maximum allowed distance between the rack
and the machine’s in-feed arrangement is 500 mm.

HakkiFeed 422 rev. A Translated Version 1-2019
3.1.2. Connecting the hydraulics
Use the operator’s manual of the
relevant Hakki Pilke firewood processor
for the connections!
Use of the rack requires two separate
control valves: Example Figure 3.
In-feed conveyor A (Figure 1)
-Connected in series to the Hakki
Pilke firewood processor’s in-feed
system (quick couplings C(red) and
D(black))
Note! If the machine features the
valve shown in Figure 3, it must be
opened to ensure oil flow through
the quick couplings.
Feeder C (Figure 1)
-Connected to the accessory valve
of the Hakki Pilke firewood
processor (quick couplings A(red)
and B(black))
Ensure that all connections are safe and
secure!
Figure 3.
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. Make sure that you are familiar with the functions of the machine's controls. If necessary, see Section 3.
2. Operate in-feed conveyor A (Figure 2) empty, and ensure that the rollers run freely and in the right
direction.
3. Use feeder C unloaded and ensure that it can move freely in both directions.
4. Load logs onto table B, and use one log to test the operation before beginning actual work.

7 / 19
HakkiFeed 422 rev. A Translated Version 1-2019
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. Loading logs onto the log rack
Use a forklift or tractor with a sufficiently long fork to ensure safe loading.
-Load the first log against the feeder –do not drop the log.
-Lower the following logs carefully on the rack –do not drop them.
-Load the logs on the machine with the stem end first, and ensure that the centre of gravity is in the
middle so that the logs cannot tip to the side off the rack.
-Do not exceed the load-bearing capacity of the rack (Section 1.3), and leave enough room for the free
operation of feeder C.
-Smaller logs can be stacked on top of each other, but a total height of 40 cm must not be exceeded.
Note! Ensure that there are no other people in the vicinity of the machine when loading logs!
Note! Ensure that the log’s centre of gravity stays on the conveyor!
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 of the
machine’s guards or components need 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. Tightening
Check the tightness of the log rack bolts at regular intervals. Inspect the rack visually before each instance of
use.
5.2. Lubrication
There are a total of six lubrication points in the machine, presented in the figures below.
1. In-feed conveyor bearings (B) 2 pcs, Figure 6:B (every 200 hours)
2. Feeder bearings (A) 2 pcs, Figure 6:A (every 200 hours)
3. Feeder cylinder nipples 2 pcs, Figure 6:C (every 50 hours)
Note! Take care when applying grease to dustproof bearings!

5.3. Washing and cleaning
Loose debris and sawdust can be cleaned from the machine with pressurised air, for example. The machine
can also be washed with a high-pressure washer as long as the water jet is not aimed directly at the bearings.
Always ensure that the machine and the working area are sufficiently clean during operation. The machine
must always be cleaned after use. Clean the machine at suitable intervals and always before storing the
machine for a prolonged time. After washing, the machine must be lubricated according to the instructions in
Section 5.2.
6. Storage
Although the machine is intended for outdoor use, it should be covered and stored in a sheltered location or
indoors. Before prolonged storage, the machine must first be cleaned, then washed according to Section 5.8
and lubricated according to Section 5.5.
