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:
oa hard hat.
oprotective shoes with slip resistant
soles.
oprotective glasses or goggles.
oheavy gloves.
owet weather gear.
orespirator or filter mask.
ohearing protection. Be aware that
prolonged exposure to loud noise
can cause impairment or loss of
hearing. Wearing a suitable
hearing protective device such as
ear muffs (A) or ear plugs (B)
protects against objectionable or
loud noises.
•Provide a first-aid kit for use in case of
emergencies.
•Keep a fire extinguisher on the machine.
Be sure the extinguisher is properly
maintained and be familiar with its proper
use.
•Keep young children away from 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.
•Wear close-fitting clothing
and cover long hair. Never
wear dangling items such
as scarves or bracelets.
•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.
•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.
•Do not modify the machine. Unauthorized
modifications may impair the function
and/or safety and affect machine life.
(continued next page)

B

Form 147398 4Revision J
•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.
•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.
•Use adequate light for the job at hand.
•Keep machinery clean. 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.

Form 147398 5Revision J
RECOMMENDED TORQUES
A. GENERAL
The tables shown below give correct torque
values for various bolts and capscrews.
•Tighten all bolts to the torques specified in
chart, unless otherwise noted throughout this
manual.
•Check tightness of bolts periodically, using
bolt torque chart as a guide.
•Replace hardware with the same strength
bolt.
•Torque figures are valid for non-greased or
non-oiled threads and heads unless otherwise
specified. Do not grease or oil bolts or
capscrews unless specified in this manual.
•When using locking elements, increase torque
values by 5%.

STEP 1. PREPARE HEADER
a. Use a lifting vehicle to raise header, or attach
header to windrower or combine and raise header
fully.
DANGER
To avoid bodily injury or death from
unexpected start-up or fall of raised header,
stop engine, remove key and engage header
lift cylinder stops before going under header
for any reason. If using a lifting vehicle, be
sure header is secure before proceeding.
b. Engage header lift cylinder stops or support
header on blocks on level ground. Blocks should
support the header approximately three feet off
the ground.

side with two 5/8 NC X 1.0 LG carriage bolts (B)
and nuts.
b. Apply grease to plastic bushings (C) and install in
each side of leg from inside.
c. Position front axle assembly (D) inside header leg
and install L-pin (E) to hold axle in place.
d. Pivot axle assembly (D) and install pivot pin (F)
into leg from inboard side. Ensure plastic
bushings (C) are not damaged when locating axle
assembly and installing pivot pin.
e. Install grease fittings in leg tube at (G).
f. Rotate pivot pin (F) to align holes in pin and axle
assembly.

harness configurations and each requires a
slightly different installation procedure. The
harness is located at the left leg.

header with a 4-pin flat connector on the wiring
harness.
INSTALLATION B – use this procedure for a 2008
header with a modified harness equipped with a 4-
pin flat connector and a 6-pin square connector.
INSTALLATION C – use this procedure for a 2008
or newer header with a 6-pin square connector.
INSTALLATION A
