Translation
Before use
 Always carry out the required preparations on both the machine and the conveyor be-
fore starting the operation.
 Make sure that all other people stay outside the operating range.
 Only use a fault-free PTO shaft and attach the chain for the shaft-guard. The permissible
revolutions range of the PTO shaft is 450–480 r.p.m.
 Only operate the machine on a sufficiently firm and level surface.
 Only operate the machine in an adequately lit space.
 Keep the tractor-powered machine connected to the three-point linkage. Also ensure that
sufficient space is provided for the PTO shaft and its guard.
 Always check that all the covers are intact and properly fastened.
 Always check that the crosscut saw-blade is intact.
 Always ensure that the electric conductors are intact.
 Always check that all the controls are operational.
 Always check the oil level and make sure that the hydraulic hoses and components are
free of damage.
 Before starting the work, make sure that the machine is firmly in position.
During operation
 Carelessness during the cut-off operation constitutes a major hazard!
 During the cut-off operation, make sure that the tree at the cutting point always leans
against the support roller of the crosscut deck and the in-feed roller: danger of rolling
over!
 Exercise particular caution when cutting knotty or crooked logs, because, as a result of
faulty cutting, the log might roll over or twist the saw-blade with enough force to break it.
 Keep the working space clean and clear of foreign objects.
 Always stop the machine and disconnect the power supply cable or the PTO shaft be-
fore servicing.
 Only cut one log at a time.
 Danger! Stay away from moving parts.
1.8 Noise emission and vibration
Equivalent continuous A-weighted sound-pressure level at the workstation is 87.5 dB (A)
and the sound power level is 102,0 dB (A). The vibration emission values do not exceed
2.5 m/s2.
1.9 Responsibilities of the operator
 The machine may only be used to produce firewood.
 All the safety-related devices are necessary to ensure a sufficient level of safety.
 The C900 is a very safe machine provided that the instructions supplied are properly
followed, the regular maintenance routines are duly executed and the work is carried
out without haste.
 It is the responsibility of the operator to ensure before the work is started that all the
safety-related devices are in perfect order and the machine has been serviced in a due
manner.
 The operator is responsible for ensuring that no one else is subjected to any danger.
 Modifying the construction of the machine is prohibited.
 The machine must never be operated under the influence of alcohol or drugs.

12 1-2017
Translation
 Remember that as the operator you are responsible for any injuries caused if safety-
related devices have been removed from the machine.
1.10 Operating conditions
 Always place the machine on as level a surface as possible.
 Prevent risks, such as slipping in winter, by organising the work site in a due manner.
 Otherwise the weather conditions do not set any restrictions on the operation. When
starting the machine in severe frost, allow it to idle at about 1/4 of the maximum speed
for about 5 to 10 minutes.
 Only operate the machine in an adequately lit space.
 It is recommended that a suitable stand be purchased or made that enables the trees
to be processed where the logs are ready at the level of the in-feed deck. Hence, un-
necessary lifting may be avoided and the work can proceed much faster. We recom-
mend using either the Palax Mega log-deck or the Palax Log log-stand.
 The most suitable temperature range for operation is approximately - 20 to +30 de-
grees Centigrade. Otherwise, the weather conditions do not set any restrictions on the
operation.
 Make sure that no other people, especially children, are present inside the operating
range.
 Never use the machine indoors, owing to the risk of dust generation or the danger of
exhaust gases.
1.11 Terms of warranty
The warranty period runs for 12 months from the date of purchase.
The warranty covers:
 Parts which have been damaged during normal operation of the machine due to any
defects in material or workmanship.
 The reasonable repair cost as set forth in the agreement between the buyer and the
manufacturer.
 A new part is delivered as a replacement for the defective one.
The warranty does not cover:
 Defects due to normal wear, faulty operation or negligent maintenance.
 The crosscut saw-blade, the in-feed belt, the V-belts and oils.
 Defects in the machine due to any modifications which the buyer has made or ordered
from a third party and which have affected the machine in such a way that it can no
longer be considered to correspond to its original configuration.
 Other possible expenses or financial claims due to the above-mentioned
measures.
 Indirect expenses and/or travel costs incurred while making repairs under warranty.
 For parts changed during the warranty period, the warranty expires at the same time as
the warranty period of the machine.

2.8 Adjusting the cutting length, Fig. 6
 The machine is equipped with a special Palax Optimi cutting length adjuster, which ad-
justs the stroke length of the splitting cylinder in accordance with the desired cutting
length.
 Adjust the cutting length using the control lever (OPTIMI, Fig.11) and the scale on the
machine’s frame (Fig. 6).
 As the crosscut blade lowers, the log-stop automatically turns away from the log, allow-
ing it to fall down freely.
 The log-stop is equipped with one shear-pin.
 The shear-pin is intended for protecting the log-stop structure against damage that may
occur if a tree of excess length ends up in the splitting chute and the pusher pushes it
to a vertical position against the log-stop.
 Bolt size M6 x 50, partial thread, strength class 8.8, M6 Nyloc nut.
3 OPERATION OF THE FIREWOOD PROCESSOR POWERED BY
DIFFERENT POWER SOURCES
3.1 Testing the machine
 When starting the machine in severe frost, allow it first to idle at low speed for about 5
minutes; this warms up the oil.
 While the motor is running, check that the hydraulic system and the controls for shut-
ting off are operational.
 Test that the safety limit switches are operating when the cover is opened. Once the
cover is open, the hydraulic valves cannot be operated with the exception of the fire-
wood conveyor.
 If you observe even a minor malfunction in the operation of the machine, find out the
cause and repair it!
 The machine must always be tested before starting its use.
NOTE ! Stop the machine and disengage the power take-off of the tractor or
disconnect the power cord from the socket to locate and repair a possible fault in
the machine!
3.2 Powered by a tractor
 The PTO shaft must be able to transmit an output of about 26 kW: for example,
BONDIOLI 143, WALTERSCHEID W 2300 or EGT40.
 No safety clutch is required for the PTO shaft.
 Only use fault-free PTO shafts and always attach the chains for the shaft-guard to the
machine.
 When you disconnect the PTO shaft from the tractor, hang it on the hook on the ma-
chine.
 The suitable range of speeds for the PTO shaft is from min. 450 to max. 480 r.p.m.
3.3 Suitable revolutions range for the PTO shaft
 The recommended rotation speed for the PTO shaft is about 470 r.p.m.

17 1-2017
Translation
 If the angular gear revolutions and the cutting speed of the crosscut blade are suffi-
cient, less load will be subjected to the transmission.
3.4 Disengagement lever for transmission, Fig. 7
 The machine is equipped with a special device for disengaging the transmission be-
tween the angular gear and the machine to make the hydraulic pumps and the crosscut
saw-blade stop.
 In the event of emergency, pull the lever A downward. Thus will the lock-up bolt B lock
the lever and the V-belts will remain slack.
Fig. 7
NOTE ! Only use the lever in an emergency, because the V-belts, which slightly
chafe the angle-drive pulley, may wear too quickly.
3.5 Required measures in an emergency situation
If the switch has been used in an emergency situation, e.g. when a log has stuck in the cir-
cular saw-blade as a result of a mistake during the sawing, immediately also switch off the
power take-off transmission of the tractor (tractor-powered machine), because the pulley of
the angle drive can wear down the V-belts unnecessarily.
NOTE! Release the disengagement lever for the transmission before restart-
ing the machine.
3.6 Starting under cold conditions (machine powered by a tractor)
 When starting the machine in severe frost, allow it first to idle at low speed for about 5
minutes; this warms up the oil.
 Warming up the oil reduces wear on the hydraulic system significantly and prevents
damage.
3.7 Electric drive, start and emergency stop.
 The output of the motor is 15 kW and its speed is 1,480 rpm.
 The machine is equipped with an automatic Y-D starter with an emergency stop fea-
ture.
 All the electric installations have been made ready.
 The cross-section of the extension cord required for a tension of 400 V must be 6 mm2.

18 1-2017
Translation
 When starting up the machine, check that the direction of rotation corresponds to the
arrow on the blade cover.
 To check the direction of rotation, run the motor for a short while and then stop it sud-
denly.
 The direction of rotation is reversed using the phase-switch in the appliance inlet.
 The machine may only be connected to a power supply equipped with a fault current
switch of 30 mA.
 The machine must be equipped with a 5-pole extension cord (L1, L2, L3, N ja PE) to
operate.
NOTE ! Electric work may only be carried out by a professional person.
3.8 Starting the electric motor using the Y/D starter, Fig. 8
 Press the start button A. In the Y-position the motor starts rotating at slow speed with
low output. The start phase takes several tens of seconds.
 As the engine speed increases, the D-position is automatically switched on and the
motor quickly reaches full speed.
 At the same time, the signal light B between the pushbottons illuminates.
 Stop the engine using the pushbutton C.
Fig. 8
NOTE ! The machine must not be operated until the motor is running at full
speed.

19 1-2017
Translation
3.9 Emergency stopping of an electrically powered machine, Fig. 8
 Push down the emergency stop button D.
 Turn the pushbutton clockwise to release it.
3.10 The machine is equipped with a system to prevent simultaneous op-
eration in two modes, Fig. 9
 When the cover plate Bis turned down, it is possible to connect the extension cord.
When the cover is raised up, it is possible to connect the PTO shaft.
 Suspension hook Afor the PTO shaft.
Fig. 9
WARNING! Never remove from the machine the plate that prevents the simultane-
ous operation in two modes.
Always remove the PTO shaft before operating the machine by electricity.
3.11 Operation under cold conditions
When an electrically powered machine is operated in a temperature below -10 degrees
Centigrade, we recommend using less viscous hydraulic oil, such as ISO VG22S multi-
grade oil or synthetic hydraulic fluid, because a machine with electric drive takes full revo-
lutions right from the start of operation.
In cold weather, it pays to reduce the speed of the discharge conveyor to a minimum. Do-
ing it this way requires the least power at the start-up stage.
It also pays to pull down the disengagement lever for the transmission for a cold start.
Then only the angular gear will start running and the gearbox oil will warm up. After this,
stop the machine, release the disengagement lever for the transmission and restart the
machine.

NOTE !The protective net for the splitting chute shall be closed during start-up of
the electric motor.
3.12 Electric heater for oil tank
A 300 W electric heater carpet with adhesive tape attachment and a thermostat is availa-
ble as an option for the hydraulic oil tank. The starter comes as standard equipped with an
operating switch for the heater, Fig 8 E. Heating the oil for 1-2 hours is sufficient to enable
smooth starting.
 The size of the heater carpet is 200 x 300 mm
 Output 300 W
 Equipped with a thermostat
 Strongly adherent glue for attachment of the carpet
NOTE! Only a skilled craftsman is allowed to carry out electrical work for the
heater.
4 FULL-HYDRAULIC CONTROL
Crosscutting, automatic starting of the splitting and operation of the in-feed conveyor are
effortlessly controlled using the fully hydraulic joystick-valve.
4.1 Mastering the safety devices
While the protective net for the splitting chute is closed, access is prevented to the operat-
ing area of the crosscut saw-blade and the pusher. As the protective net for the splitting
chute is opened, the crosscut saw-blade cover is activated and the operation of the cross-
cut saw-blade, the pusher, the wood length adjuster (Palax Optimi) and the adjustment of
