10
Palax C750 Translation 1-2018

Never remove any safety-related devices from the machine.
 The width of the machine equipped with the 4,3-m conveyor is about 2.83 m. This
means that, depending on the size of the tractor, the transport width of the conveyor
may extend outside the rear wheel on the right-hand side.
The operator
 Every person operating the machine, must thoroughly study the entire user manual.
 Always use eye guards and hearing protectors.
 Always wear protective shoes.
 Always wear work gloves.
 Do not wear loosely-fitting clothing.
Before use
 Always carry out the required preparations on both the machine and the conveyor
before starting the operation.

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 infeed 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-bar 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 power take-off
shaft before servicing.
 Only cut one log at a time.
 Danger! Stay away from moving parts.
1.8 Noise emission and vibration

2.5 m/s2.

11
Palax C750 Translation 1-2018
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 PALAX C750 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.
 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,
unnecessary lifting may be avoided and the work can proceed much faster. We
recommend 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
degrees 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

 The log-stop A can be set to any position between 25 and 55 cm.
 Set the desired cutting length using the scale, and tighten the log-stop screws with a
wrench.
 As the crosscut blade lowers, the log-stop automatically turns away from the log,
allowing it to fall down freely.
 The log-stop is equipped with two shear-pins B.
 The shear-pins are 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 M 8 x 100, partial thread, strength class 8.8, M8 Nyloc nut.
NOTE ! Always put the nut on the log-stop plate side.
3 OPERATION OF THE FIREWOOD PROCESSOR POWERED BY
DIFFERENT POWER SOURCES
3.1 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 in the hook on the
machine.
 If the power take-off of the tractor has a high-speed range, it is recommended to use it,
because the horsepower requirement of the Firewood Processor is small. The suitable
range of speeds for the PTO shaft is from min. 450 to max. 540 rpm.
3.2 Emergency stop switch of the tractor powered machine, Fig. 9
 The tractor-powered machine is equipped with a special Rapid Stop Device which
disengages the transmission from the angular gear to the machine in a matter of
seconds and stops the operation of the machine completely.
 In an emergency situation, push lever A upwards to the point where it locks. In this
8
B
A

17
Palax C750 Translation 1-2018
position, the drive belts are loose.
9
A
NOTE ! Only use the lever in an emergency, because the V-belts, which slightly
chafe the angle-drive pulley, may wear too quickly.
3.3 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
circular saw-blade as a result of a mistake during the sawing, immediately also switch off
the power take-off transmission of the tractor, because the pulley of the angle drive can
wear down the V-belts unnecessarily.
NOTE ! Switch the Rapid Stop Device back to the operation position before
engaging the transmission of the tractor.
3.4 Starting under cold conditions
 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.
3.5 Electric drive, start and emergency stop, Fig. 10
 The power output of the motor is 12,6 kW and the speed is 1,480 rpm.
 The machine is equipped with an automatic Y-D starter with an emergency stop
feature.
 All the electric installations have been made ready.
 The cross-section of the extension cord required for a tension of 380 V must be at least
6 mm
2
.Fuse size: minimum 25A
 When starting up the machine, check that the direction of rotation corresponds to the
arrow at the end of the motor.
 To check the direction of rotation, run the motor for a short while and then stop it
suddenly.
 The motor A and the starter B are located under the protective cover.

18
Palax C750 Translation 1-2018
NOTE ! Only a skilled craftsman is allowed to change the direction of rotation.
NOTE ! Only use an extension cord equipped with a changeover switch for
rotation direction of the motor that can be turned by screwdriver.
3.6 Starting the electric motor
 Press the start button. 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 switched on and the motor quickly
reaches full speed. As the motor reaches full revolutions, the signal light on the starter
illuminates.
NOTE ! The machine must not be operated until the motor is running at full
speed.
3.7 Emergency stop of a machine powered by electric motor, Figure 10
 Push down the emergency stop button B.
 Turn the pushbutton clockwise to release it.

WARNING! Never remove from the machine the plate that prevents the
simultaneous operation in two modes. Always remove the power take-off shaft
before operating the machine by electricity.
3.9 Operation under cold conditions
When an electric motor-powered machine is operated in temperatures below -15 degrees
Centigrade, the use of a less viscous hydraulic oil is recommended, because a machine
with electric drive takes full revolutions right from the start of operation. Suitable oils are,
for example, ISO VG22S multigrade oil or synthetic hydraulic fluid.
