SAFETY OPERATING
CABIN PROTECTIVE STRUCTURES
Cabin is tested according to international ROPS,
FOPS and OPS standards.
Do not operate the machine with the door open,
secondary exit open or any of the safety covers
or protective devices removed.
It is important to keep the operator protective
structure in place (doors, screens, windows,
windshield, etc.) to minimize hazards from
whipping or intruding objects.
The protection offered by ROPS, FOPS and OPS
will be impaired if cabin
is subjected to structural damage
is involved in an overturn incident
is in any way altered by welding, bending,
drilling, or cutting
To maintain ROPS, FOPS and OPS protection,
replace damaged cabin parts immediately. A
damaged structure should be replaced, not
reused. It is forbidden to modify the window
fastening.
Following issues must be considered when the
machine is used or equipped for other purpose
than it is designed for by the manufacturer:
Overall weight of the machine without load
(towed equipment and any load excluded) must
not exceed the maximum weight defined for the
cabin and mentioned below the machine type
plate (ROPS-weight, Roll Over Protection
Structure). Contact manufacturer’s
representative to clarify the demands of the
ROPS standard when necessary.
If the machine’s center of gravity is changed
due to machine buildup the maneuverability of
the machine will also change and does not
necessarily correspond to the original demands
determined by the manufacturer.
The manufacturer can not guarantee machine
safety if the machine has been used contrary to
the operator’s instructions given or has been
equipped with accessories not approved by the
manufacturer.
NOTE: An optional heavy duty window guard is
recommended for operations in late thinning and
regeneration felling sites.
ROPS LEVELS
Cabin type plate defines approval levels and standards for ROPS (Roll-Over Protective Structures).

SAFETY OPERATING
the operating environment.
When the temperature drops below 5°C (41°F) we
strongly recommend that you use the pre-heating
(if equipped) of the engine coolant 1/2 — 1 hour
before starting the engine.
NOTE: Follow cold weather starting sequence in
this manual.
ENSURE SAFETY BEFORE DRIVING
ON FROZEN WATERS
Secure, that ice cover is strong enough before
driving machine over frozen waters.
Be ready for quick evacuation from the cabin
before driving on a frozen lake.
Release your safety belt.
Disarm the security exit.
Ensure that there is nothing to obstruct quick
evacuation.
Restore the above precautions on reaching firm
ground.
Never park the machine on a frozen lake.
AVOID FIRES AND EXPLOSIONS
When working in a forest environment, it is
impossible to prevent combustible debris from
collecting in tight corners of the machine. This
debris, in itself, may cause a fire; however, when
mixed with fuel, oil, or grease in a hot or confined
place, the danger of fire is very much increased.
To reduce the chance of a fire starting, observe
the following instructions:
23

SAFETY MAINTENANCE
SERVICE TIRES SAFELY
Explosive separation of a tire and rim parts can
cause serious injury or death.
Do not attempt to mount a tire unless you have
the proper equipment and experience to perform
the job.
Always maintain the correct tire pressure. Do not
inflate the tires above the recommended
pressure. Never weld or heat a wheel and tire
assembly. The heat can cause an increase in air
pressure resulting in a tire explosion.
When inflating tires, use a clip-on chuck and
extension hose long enough to allow you to stand
to one side and NOT in front of or over the tire
assembly. Use a safety cage if available.
Check wheels for low pressure, cuts, bubbles,
damaged rims or missing lug bolts and nuts.
SERVICE AIR CONDITIONER
SAFELY
The air conditioner must be serviced and repaired
by authorized personnel only.
Air conditioner fluid (R134a) contains fluorinated
greenhouse gases. 2.3 kg air conditioner fluid
contains 3.0 equivalent tonnes of carbon dioxide.
Heating of the refrigerant cylinder implies
increase of pressure and the danger of explosion.
The refrigerant dryer must not be heated above
50°C (122°F), as this may otherwise cause it to
explode due to excessive pressure of the
refrigerant. In the event of fire spray the dryer
liberally with water to keep it cool.
The gas is asphyxiating without forewarning. The
gas is colourless, it is heavier than air and
spreads close to the ground.
Splashes of the fluid cause frost injuries to the
skin and serious eye damage. Spilled refrigerant
fluid has extremely low temperature and it
vaporizes quickly. Dissipates in contact with fire,
giving off toxic fumes.

OPERATING THE MACHINE BOOM AND HARVESTER HEAD
SYSTEM BACKUP
The IBC system was designed in a failure proof
way and thus cannot cause machine down faults.
In the event of a sensor failure in the IBC system,
the operator can change software to traditional
controls by switching off the IBC system with a
specific button combination – R60 (F1) + L18
(boom icon). When switching off the IBC system,
the control system bypasses IBC activities with
traditional controlling directly via the boom valve.
IMPORTANT: In the event of a CAN bus failure in
the IBC sensor bus. Sensor bus can be by-
passed to restore CAN data connection for RLC
and VSS.

GENERAL MAINTENANCE FLUIDS AND LUBRICANTS
Cold weather flow degradation
Stability and storage issues (moisture absorption, oxidation, microbial growth)
Possible filter restriction and plugging (usually a problem when first switching to biodiesel on used
engines.)
Possible fuel leakage through seals and hoses
Possible reduction of service life of engine components
The following must also be considered when using biodiesel blends above B20.
Possible coking and/or blocked injector nozzles, resulting in power loss and engine misfire if John
Deere approved fuel conditioners containing detergent/dispersant additives are not used
Possible crankcase oil dilution, requiring more frequent oil changes
Possible corrosion of fuel injection equipment
Possible lacquering and/or seizure of internal components
Possible formation of sludge and sediments
Possible thermal oxidation of fuel at elevated temperatures
Possible compatibility issues with other materials (including copper, lead, zinc, tin, brass, and bronze)
used in fuel systems and fuel handling equipment
Possible reduction in water separator efficiency
Potential high acid levels within fuel system
Possible damage to paint if exposed to biodiesel
IMPORTANT: Raw pressed vegetable oils are NOT acceptable for use as fuel in any concentration in
John Deere engines. Their use could cause engine failure.
MINIMIZING THE EFFECT OF COLD WEATHER ON DIESEL ENGINES
John Deere diesel engines are designed to operate effectively in cold weather.
However, for effective starting and cold weather operation, a little extra care is necessary. The
information below outlines steps that can minimize the effect that cold weather may have on starting and
operation of your engine.
USE WINTER BLEND DIESEL FUEL
When temperatures fall below -10ºC (14ºF), winter blend diesel fuel is best suited for cold weather
operation. Winter blend diesel fuel has a lower cloud point and a lower pour point.
Cloud point is the temperature at which wax will begin to form in the fuel and this wax causes fuel filters to
plug. Pour point is the lowest temperature at which movement of the fuel is observed.
NOTE: On an average, winter blend diesel fuel has a lower BTU (heat content) rating. Using winter
blend diesel fuel may reduce power and fuel efficiency, but should not cause any other engine
performance effects. Check the grade of fuel being used before troubleshooting for low power
complaints in cold weather operation.
SEASONAL VISCOSITY OIL AND PROPER COOLANT CONCENTRATION
Use seasonal grade viscosity engine oil based on the expected air temperature range between oil
changes and a proper concentration of low silicate antifreeze as recommended. (See DIESEL ENGINE
OIL and ENGINE COOLANT requirements this section.)
DIESEL FUEL FLOW ADDITIVE
Use John Deere Premium Diesel Fuel Conditioner (winter formula) which contains anti-gel chemistry, or
equivalent to treat Grade No.2-D fuel during the cold weather season. This generally extends operability
about 10ºC (18ºF) below its Cloud Point. For operability at temperatures further below, winter grade fuel
(a blend of No.2-D and No.1-D, or straight No.1-D fuel) is best suited for cold weather operation.
IMPORTANT: Treat fuel when outside temperature drops below 0ºC (32ºF). For best results, use with
untreated fuel. Follow all recommended instructions on label.
BIODIESEL
When running with BIODIESEL blends wax formation can generate at warmer temperatures. Begin to use
