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 table for operation, ensure that it is positioned on an even and firm foundation so that
the logs on the table are straight. Make sure that the machine’s hydraulic hoses cannot be caught between
moving parts or cause a hazard.
When arranging the machine for transport, clear the table of wood 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. Connecting the hydraulics
Use the operator’s manual of the
relevant Hakki Pilke firewood processor
for the connections!
Use of the table requires two separate
control valves: Example Figure 3.
In-feed conveyor A (Figure 2)
-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.
Chain conveyor B (Figure 2)
-Connected to the accessory valve
of the Hakki Pilke firewood
processor (quick couplings A(red)
and B(black))
-Chain conveyor motor’s spill hose
(from the motor end): connect the
hose directly to the machine’s
hydraulic oil tank
Note! Dispenser D runs when chain
conveyor B is being operated.
Figure 3.
Ensure that all connections are safe and secure!

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 C (Figure 2) empty, and ensure that the rollers run freely and in the right
direction.
3. Operate chain conveyor A empty, and ensure that the chains run freely and in the right direction.
4. Load logs on chain conveyor A, and use one log to test the operation before beginning actual work.
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 chain conveyor
Use a forklift with a sufficiently long fork to ensure safe loading.
-Always load logs from the chain conveyor side.
-Lower the logs on the chains carefully. Never drop logs on the chains.
-Load logs in 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 conveyor.
-Do not exceed the load-bearing capacity of the table (Section 1.3), and leave enough room for the free
operation of dispenser B.
-Smaller logs can be stacked on top of each other, but a total height of 50 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 the
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. Chains
Tighten the chains of chain conveyor A in accordance with Figure 4. Adjust them by opening the tensioning
nut as shown in Figure 4 on the left. The figure on the right shows the tightened tensioning nut after
adjustment. The tightness is correct when the chain hangs in the housing about 10 mm from the bottom and
rises about 100 mm when lifted from the centre. Excessively tight chains move sluggishly and excessively
loose chains increase wear or cause jams.
Figure 4 (Adjusting the tightness of the chain conveyor’s chains)
Tighten the motor chain by opening the motor guard of chain conveyor A. The correct tightness is presented
in Figure 5 to the left. Tension the chain as follows:
Open the three motor fastening screws in Figure 5 (pictured in the centre).
Open locking nut B, tighten bolt A and finally lock the locking nut and tighten the motor’s
fastening screws (in the middle).
