A warning alarm and warning lamp will be
activated in the event of machine faults.
Never continue running a machine when the alarm
has been given, unless you have checked the
cause and taken necessary action.
KEEP DANGER ZONE CLEAR
Danger zone applies when the machine is in
operation. The operator is personally responsible
for maintaining this safety rule in the absence of
the foreman.
Danger zone for harvesters is 90 meters (300 ft)
and for forwarders and bundlers 20 meters (70 ft).
When the engine is running, allow no one in the
danger zone of the machine.
Maintain a safe operating distance between the
equipment and other personnel. Never swing the
boom, attachment, or trees over the heads of
bystanders.
Check that no-one is in the line of the blade during
sawing. Should the saw chain break, fragments
may fly off, causing a risk of accidents.
When you stop working, even temporarily, lower
the boom and set the harvester head or grapple
safely down so that it cannot move.

MACHINE SYSTEMS AND COMPONENTS OPTIONAL EQUIPMENT
OPTIONAL EQUIPMENT
The machine can be equipped with various different optional equipment.
CENTRAL GREASING SYSTEM
The machine can be equipped with an automatic lubrication system. The system consists of a grease
pump with an integrated grease reservoir (1), grease dispenser blocks (2) for distributing the grease to
the right locations and grease lines (3) between the pump, dispensers and greasing points.
Direct supply lines from the pump go to the main dispenser and the boom dispenser. Grease supply to
secondary dispensers for frame bearing, middle joint, cabin leveling and rotating unit and rear frame go
via the main dispenser.
Operation
The greasing pump works only when the machine’s diesel engine is running. Once the needed greasing
interval is set from the pump unit the system operates fully automatically. When the grease level in the
reservoir gets low the TimberMatic™ gives an alarm.
The grease pump can be forced to run for four minutes by pressing the F2 function (L14) and vacuum
pump (R56) buttons (4, 5) simultaneously.
SAFETY INSTRUCTIONS
Appropriate use
Use the lubrication pump and progressive divider valves only for dispensing lubricants in centralized
lubrication systems. The system is designed for intermittent operation.

MACHINE SYSTEMS AND COMPONENTS OPTIONAL EQUIPMENT
FORWARDER IBC
IBC system can be mounted to CF5, CF7, CF7S
and CF8 booms as an optional feature. This
option allows operators to focus on grabbing the
stems, since the operator controls the boom tip
directly instead of controlling independent boom
joint movements.
A few proven advantages of IBC:
The boom is easy and smooth to control. The
system is easy to understand.
Productivity is improved with faster cycle times.
Boom durability is better due to soft movements
and electrical end damping.
IBC SENSOR BUS
IBC system components:
1. Main boom cylinder
2. Jib boom cylinder
3. Extension boom cylinder
4. Rear MECA controller (RFC)
When operating the IBC system in G-model
machines, cylinders with embedded sensoring
(1,2,3) provide displacement data via CAN bus to
the rear MECA controller (4). The IBC sensors
are defined under CAN 3 "sensor bus" in the
machine’s control system. Rear MECA controller
(RFC) processes sensor inputs from cylinders
and compares this data through actuator
algorithms along with inputs provided by the
operator via joystick commands. As a result IBC
system provides independent valve control
commands to the boom valve. Control commands
for the rotator and grapple are not affected by the
IBC system.

MACHINE SYSTEMS AND COMPONENTS OPTIONAL EQUIPMENT
PRE-HEATER
The purpose of the pre-heater system is to warm
up the engine, hydraulic oil and the cabin prior to
starting the engine and machine operation. The
pre-heater is recommended for use when the
ambient temperature is below 5° Celsius (41
°Fahrenheit). Pre-heating eliminates excessive
fuel consumption, pollution and engine wear
during a cold start.
The pre-heater is started with the timer, either
directly or at a preset time. Or by using remote
control if equipped via an optional pre-heater
modem.
Operation with biodiesel (FAME for diesel
engines according to DIN EN 14 214)
The pre-heater model (M8) must be biodiesel
compatible. When the pre-heater model is
approved for operation with biodiesel up to a
temperature of minus 8° Celsius (17.5 F°) the
flowability reduces at temperatures below 0 °C
(32 °F).
Other pre-heater models (M10) can use biodiesel
blends up to 10 %.
Heating mode at high altitudes – up to 3500 m
The combustion behaviour of the pre-heater
changes with increasing altitude, due to the lower
air density. The pre-heater has an automatic
altitude detection device. The combustion ratio
between fuel and air is adapted to the ambient
conditions by reducing the fuel quantity.

CONTROLS AIR CONDITIONER
TEMPERATURE
Temperature setting affects to the water valve
position, if the fan speed is set to AUTO or
manual position When the fan position is set to
OFF, the water valve is closed.
AUTO
The water valve position is automatically
controlled in according to the temperature setting,
internal and external temperatures.
LO
The water valve is fully closed independently of
the internal and external temperatures and the AC
compressor is enabled.
HI
The water valve is fully open independently of the
internal and external temperatures and the AC
compressor is disabled.
RECIRC MODE
When the RECIRC mode is enabled, outside air is prevented from entering into the vehicle. When the
RECIRC mode is disabled, then the fresh/recirc door will be set to allow fresh air enter to the cabin. A
panel indicator light indicates when the RECIRC mode is active.
In recirculation mode, only recirculated air is pulled in through the unit. Use this mode for short periods of
time to prevent fumes from entering the cab or to obtain maximum cooling or heating.
The unit draws in a mix of outside and recirculated air when in fresh air mode. This allows the cab to
maintain a positive cab air pressure to prevent excessive dust from entering the cab. In addition, the
fresh air mode prevents the air from becoming stale and humid.
NOTE: Constant use of full recirculation also increases the carbon dioxide level of the cabin thus
resulting in poor air quality.
NOTE: Inspect and replace both the fresh air and recirculated air filters regularly to obtain proper cab
pressurization, optimized unit performance, and correct temperature regulation.
DEFROST
In certain cold or humid conditions, more heat and airflow is required to clear the windows. The set point
temperature and the blower speed should be adjusted as necessary to maintain a clear windshield at all
times. For maximum defrost, set the temperature control to “HI” on the control panel, and turn the blower
fan speed to maximum fan.
Enable the air conditioner to faster defrost. The A/C is used to dehumidify the air entering the cab to
remove the fog from the windshield.

OFF-ROAD DRIVING
During off-road operation, low gear is engaged (all-wheel-drive mode is on). The machine is steered by
means of the joystick on the left control keypad.
IMPORTANT: Deactivated on-road driving switch is a precondition when trying to operate following
features: boom movements, cabin rotation, cabin leveling and cabin work lights.
1. Turn off the parking brake. The work brake will engage automatically. Raise the stairs, if not raised
automatically by parking brake switch.
2. Turn on the boom and the working rpm when the TimberMatic is turned on (now you can use the boom
and harvester head functions).
3. Engage low gear (the driving direction switch has to be in neutral).
4. Select the driving direction.
5. Press the accelerator pedal. This will automatically disengage the work brake and the machine will start
moving.
6. The speed of the machine is controlled with the drive pedal. As soon as the pedal is pressed past the
constant speed position, the speed of the diesel engine also starts picking up in relation to the position
of the pedal.
Off-road driving with the working rpm engaged is suggested especially when boom and harvester head
are operated at the same time. If you do not want to use the working rpm in off-road driving, the operation
is similar to what has been described above, but regulating the machine speed with the drive pedal has a

OPERATING THE MACHINE BOOM AND GRAPPLE
IBC MODE
NOTE: IBC is an optional feature requiring
special boom components and separate
activation.
In order to use the boom in IBC mode, press the
following button combination – R60 (F1) + L18
(boom icon). If the button combination is pressed
again operator is able to return to the normal
boom mode.
IBC mode can also be actived in "Activate
Functions" pop-up menu while enabling other
boom functions. Separate IBC activation
checkbox is available when activating the boom
(button L18).
When entering IBC mode, the boom symbol with
IBC text appears on the bottom right field of
TimberMatic™ display.
When using the boom in IBC mode, boom controls
are IBC specific and the operator controls the
boom tip movements directly (three main
cylinders) instead of individual cylinders. Also
since IBC activities are heavily controlled by the
onboard automation system, all IBC related
control, adjustment and calibration procedures are
performed with TimberMatic™. Notice that
TimberMatic™ has a separate menu for the IBC
functions in relation to the traditional boom control
menu.
SPECIAL FUNCTIONS
Unloading mode
This function is controlled by the operator with on/off switching. The unloading mode is activated by
pressing boom autotilt button R57 (IBC mode needs to be on). When the mode is active, this is indicated
with a separate symbol in the work mode. Unloading mode minimises the use of the extension boom when
handling exceptionally heavy loads.
NOTE: Unloading mode can also be utilized when operating in slope conditions if extension boom feels
too active.
Load space functionality
This function is automatically controlled by the IBC system. Functionality minimises the usage of the
extension boom while operating in the load space.
Switching to travel position
The IBC system switches to normal boom operating mode when bringing the grapple near the
transportation position. The grapple needs to be near the headboard and low enough in the load space in
order to accurately control the folding of the boom into travel position. Operator is unable to activate
unloading mode until boom is moved from transportation position.

GENERAL MAINTENANCE FLUIDS AND LUBRICANTS
Your equipment can operate at top efficiency only when clean lubricants are used.
Use clean containers to handle all lubricants.
Whenever possible, store lubricants and containers in an area protected from dust, moisture, and other
contamination. Store containers on their side to avoid water and dirt accumulation.
Make certain that all containers are properly marked to identify their contents.
Properly dispose of all old containers and any residual lubricant they may contain.
MIXING OF LUBRICANTS
In general, avoid mixing different brands or types of oil.
Oil manufacturers blend additives in their oils to meet certain specifications and performance
requirements.
Mixing different oils can interfere with the proper functioning of these additives and degrade lubricant
performance.
Consult your John Deere dealer to obtain specific information and recommendations.
ENGINE COOLANT
Failure to follow applicable coolant standards and drain intervals can result in severe engine damage that
may not be covered under warranty.
The engine cooling system is filled to provide year round protection against corrosion and cylinder liner
pitting, and winter freeze protection to -37°C (-34°F). If protection at lower temperatures is required,
consult your John Deere dealer for recommendations.
The following engine coolants are preferred:
John Deere COOL-GARD™ II Premix
John Deere COOL-GARD™ II PG Premix
Use John Deere COOL-GARD™ II PG Premix when a non-toxic coolant formulation is required.
The following engine coolant is also recommended:
John Deere COOL-GARD™ II Concentrate in a 40–60% mixture of concentrate with good quality
water.
John Deere COOL-GARD™ II Premix, COOL-GARD™ II PG Premix, and COOL-GARD™ II Concentrate
coolants do not require the use of supplementary coolant additives.
IMPORTANT: When mixing coolant concentrate with water, do not use less than 40% or greater than
60% concentration of coolant. Less than 40% gives inadequate additives for corrosion protection.
Greater than 60% can result in coolant gelation and cooling system problems.
Other coolants
John Deere COOL-GARD™ II and COOL-GARD™ II PG coolants may not be available in the
geographical area where servicing is performed. Other ethylene glycol or propylene glycol base coolants
may be used if they meet the following specification:
Pre-mix coolant meeting ASTM D6210 requirements
Are nitrite-free
Coolant concentrate meeting ASTM D6210 requirements in a 40—60% mixture of concentrate with
quality water
If these coolants are unavailable, use a coolant concentrate or pre-diluted coolant intended for use with
heavy-duty diesel engines and with a minimum of the following chemical and physical properties:
Formulated with a quality nitrite-free additive package.
Provides cylinder liner cavitation protection according to either the John Deere Cavitation Test Method
or a fleet study run at or above 60% load capacity
Protects the cooling system metals (cast iron, aluminium alloys, and copper alloys such as brass) from
corrosion
Freeze Protection
The relative concentrations of glycol and water in the engine coolant determine its freeze protection limit.

RESERVOIR FILLING
Always fill through the filling nipple. The best practice is to use standard refinery drums or pails. Impurities
in grease can create operational problem.
Requirements for grease classification to be used with central lubrication system in different
temperatures:
Above 0°C (32°F): NLGI 2
Below 0°C (32°F): NLGI 1
Below -20°C (-4°F): NLGI 0
It is not necessary to change the grease from NLGI 2 to NLGI 1 unless the period when temperature is
below 0°C is expected to last several days. If the temperature drops significantly below zero it is
recommended to change the grease immediately.
Do not mix two greases - consult your grease supplier first.
IMPORTANT: Use only HD lithium complex grease. Do not use calcium grease!
Emergency lubrication
The pump can be by-passed by feeding grease manually through the manual grease fitting attached on
the pressure relive valve. In case of system failure this fitting can be used for trouble shooting and
manual greasing (all points are lubricated from this one fitting).
