1.3 General Safety
CAUTION
The following are general farm safety precautions
that should be part of your operating procedure for
all types of machinery.
Protect yourself.
• When assembling, operating, and servicing machinery,
wear all the protective clothing and personal safety
devices that COULD be necessary for the job at hand.
Don’t take chances. You may need the following:
• A hard hat
• Protective footwear with slip resistant soles
• Protective glasses or goggles
• Heavy gloves
• Wet weather gear
• A respirator or filter mask
Figure 1.2: Safety Equipment
• Be aware that exposure to loud noise can cause
impairment or loss of hearing. Wear suitable hearing
protection devices such as ear muffs or ear plugs to
help protect against objectionable or loud noises.
Figure 1.3: Safety Equipment
•Provideafirst aid kit for use in case of emergencies.
• Keep a fire extinguisher on the machine. Be sure the
fire extinguisher is properly maintained. Be familiar with
its proper use.
• Keep young children away from the machinery at
all times.
• Be aware that accidents often happen when the
Operator is tired or in a hurry to get finished. Take the
time to consider the safest way. Never ignore warning
signs of fatigue.
Figure 1.4: Safety Equipment
169455 3Revision F

SAFETY
•Wearclose-fitting clothing and cover long hair. Never
wear dangling items such as scarves or bracelets.
• Keep all shields in place. Never alter or remove safety
equipment. Make sure driveline guards can rotate
independently of the shaft and can telescope freely.
• Use only service and repair parts made or approved by
the equipment manufacturer. Substituted parts may not
meet strength, design, or safety requirements.
Figure 1.5: Safety Around Equipment
• Keep hands, feet, clothing, and hair away from moving
parts. Never attempt to clear obstructions or objects
from a machine while the engine is running.
•DoNOT modify the machine. Non-authorized
modifications may impair machine function and/or
safety. It may also shorten the machine’s life.
• Stop the engine and remove the key from ignition before
leaving operator’s seat for any reason. A child or even
a pet could engage an idling machine.
Figure 1.6: Safety Around Equipment
• Keep the service area clean and dry. Wet or oily floors
are slippery. Wet spots can be dangerous when working
with electrical equipment. Be sure all electrical outlets
and tools are properly grounded.
• Keep work area well lit.
• Keep machinery clean. Straw and chaff, on a hot
engine, are a fire hazard. Do NOT allow oil or grease to
accumulate on service platforms, ladders, or controls.
Clean machines before storage.
• Never use gasoline, naphtha, or any volatile material
for cleaning purposes. These materials may be toxic
and/or flammable.
• When storing machinery, cover sharp or extending
components to prevent injury from accidental contact.
Figure 1.7: Safety Around Equipment
169455 4Revision F

SAFETY
1.4 Maintenance Safety
To ensure your safety while maintaining the machine:
• Review the operator’s manual and all safety items
before operation and/or maintenance of the machine.
• Place all controls in Neutral, stop the engine, set
the park brake, remove the ignition key, and wait for
all moving parts to stop before servicing, adjusting,
and/or repairing.
• Follow good shop practices:
– Keep service areas clean and dry
– Be sure electrical outlets and tools are
properly grounded
– Use adequate lighting for the job at hand Figure 1.8: Safety Around Equipment
• Relieve pressure from hydraulic circuits before servicing
and/or disconnecting the machine.
• Make sure all components are tight and that steel lines,
hoses, and couplings are in good condition before
applying pressure to a hydraulic system.
• Keep hands, feet, clothing, and hair away from all
moving and/or rotating parts.
• Clear the area of bystanders, especially children, when
carrying out any maintenance and repairs or when
making any adjustments.
• Install transport lock or place safety stands under the
frame before working under the header.
• If more than one person is servicing the machine at the
same time, be aware that rotating a driveline or other
mechanically driven component by hand (for example,
accessing a lube fitting) will cause drive components in
other areas (belts, pulleys, and knife) to move. Stay
clear of driven components at all times.
Figure 1.9: Equipment NOT Safe for Children
• Wear protective gear when working on the machine.
• Wear heavy gloves when working on knife components.
Figure 1.10: Safety Equipment
169455 5Revision F

SAFETY
1.5 Hydraulic Safety
• Always place all hydraulic controls in Neutral
before dismounting.
• Make sure that all components in the hydraulic system
are kept clean and in good condition.
• Replace any worn, cut, abraded, flattened, or crimped
hoses and steel lines.
•DoNOT attempt any makeshift repairs to the hydraulic
lines, fittings, or hoses by using tapes, clamps, cements,
or welding. The hydraulic system operates under
extremely high pressure. Makeshift repairs will fail
suddenly and create a hazardous and unsafe condition.
Figure 1.11: Testing for Hydraulic Leaks
•Wearprope
r hand and eye protection when searching
for a high-pressure hydraulic leak. Use a piece of
cardboard as a backstop instead of hands to isolate
and identify a leak.
•Ifinjure
d by a concentrated high-pressure stream of
hydraulicfluid, seek medical attention immediately.
Serious infection or toxic reaction can develop from
hydraulic fluid piercing the skin.
Figure 1.12: Hydraulic Pressure Hazard
• Make sure all components are tight and that steel lines,
hoses, and couplings are in good condition before
applying pressure to a hydraulic system.
