consider the safest way. Never ignore warning signs
of fatigue.
Figure 1.4
169455 3Rev. E

SAFETY
•Wearclosefitting 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
• 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.
•Do NOT modify the machine. Non-authorized
modifications may impair machine function and/or safety.
It may also shorten the machine’s life.
• Stop engine and remove 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
• Keep the area used for servicing machinery 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.

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.
•Placeallcon
trols 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 area clean and dry.
–Besureele
ctrical outlets and tools are properly
grounded.
– Use adequate light for the job at hand. Figure 1.8: Slip on Puddle
• Relieve pressure from hydraulic circuits before servicing
and/or disconnecting the machine.
• Before applying pressure to a hydraulic system, make
sure all components are tight and that steel lines, hoses,
and couplings are in good condition.
• Keep hands, feet, clothing, and hair away from all moving
and/or rotating parts.
•Clearth
e area of bystanders especially children when
carrying out any maintenance and repairs or when
making any adjustments.
•Instal
l transport lock or place safety stands under the
frame before working under the header.
•Ifmore
than one person is servicing the machine at the
same time,beawarethatrotatingadrivelineorother
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: Keep Away
• Wear protective gear when working on the machine.
• Wear heavy gloves when working on knife components.

SAFETY
1.5 Hydraulic Safety
• Always place all hydraulic controls in Neutral before
dismounting.
• Makesurethatall components in the hydraulic system
are kept in good condition and clean.
•Replaceanyw
orn, cut, abraded, flattened, or crimped
hoses and steel lines.
• Do not 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. Such makeshift repairs will fail
suddenly and create a hazardous and unsafe condition.
Figure 1.11: Checking Hydraulic Leaks
• Wear proper 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
aleak.
• If injured 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
• Before applying pressure to a hydraulic system, make
sure all components are tight and that steel lines, hoses,
and couplings are in good condition.
