2.4 GENERAL SAFETY
CAUTION
xThe following are general farm safety
precautions that should be part of your
operating procedure for all types of
machinery.
xProtect yourself.
xWhen 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.
xYou may need:
xa hard hat.
xprotective shoes with slip resistant
soles.
xprotective glasses or goggles.
xheavy gloves.
xwet weather gear.
xrespirator or filter mask.
xhearing 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.
xProvide a first-aid kit for use in case of
emergencies.
xKeep a fire extinguisher on the machine.
Be sure the extinguisher is properly
maintained and be familiar with its proper
use.
xKeep young children away from
machinery at all times.
xBe 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.
xWear close-fitting
clothing and cover long
hair. Never wear
dangling items such as
scarves or bracelets.
xKeep hands, feet, clothing and hair away
from moving parts. Never attempt to
clear obstructions or objects from a
machine while the engine is running.
xKeep all shields in place. Never alter or
remove safety equipment. Make sure
driveline guards can rotate
independently of the shaft and can
telescope freely.
xUse only service and repair parts made
or approved by the equipment
manufacturer. Substituted parts may not
meet strength, design, or safety
requirements.
xDo not modify the machine. Unauthorized
modifications may impair the function
and/or safety and affect machine life.
xStop 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.

with electrical
equipment. Be
sure all
electrical
outlets and tools are properly grounded.
xUse adequate light for the job at hand.
xKeep machinery clean. Do not allow oil or
grease to accumulate on service
platforms, ladders or controls. Clean
machines before storage.
xNever use gasoline, naphtha or any
volatile material for cleaning purposes.
These materials may be toxic and/or

6 OPERATION
6.1 OWNER/OPERATOR
RESPONSIBILITIES
CAUTION
xIt is your responsibility to read and
understand this manual completely
before operating the windrower. Contact
your dealer if an instruction is not clear
to you.
xFollow all safety messages in the
manual and on safety signs on the
machine.
xRemember that YOU are the key to
safety. Good safety practices protect
you and the people around you.
xBefore allowing anyone to operate the
windrower, for however short a time or
distance, make sure they have been
instructed in its safe and proper use.
xReview the manual and all safety related
items with all operators annually.
xBe alert for other operators not using
recommended procedures or not
following safety precautions. Correct
these mistakes immediately, before an
accident occurs.
xDo not modify the machine.
Unauthorized modifications may impair
the function and/or safety and affect
machine life.
xThe safety information given in this
manual does not replace safety codes,
insurance needs, or laws governing
your area. Be sure your machine meets
the standards set by these regulations.
xEnsure that the windrower is properly
equipped to safely operate the header.
This may include adding ballast
according to Windrower Operator’s
Manual requirements for attachments of
this size and mass.
6.2 OPERATIONAL SAFETY
Follow these safety precautions:
CAUTION
xFollow all safety and operational
instructions given in your windrower
Operator's Manual. If you do not have a
windrower manual, get one from your
dealer and read it thoroughly.
xNever attempt to start the windrower
engine or operate the windrower except
from the operator’s seat.
xCheck the operation of all controls in a
safe clear area before starting work.
xDo not allow riders on windrower.
xNever start or move the machine until
you are sure all bystanders have cleared
the area.
xAvoid travelling over loose fill, rocks,
ditches or holes.
xDrive slowly through gates and
doorways.
xIf cutting ditch banks, use extreme
caution. If the header hits an
obstruction, the front of the windrower
will usually swerve towards the ditch.
xWhen working on inclines, travel uphill
or downhill when possible.
xNever attempt to get on or off a moving
windrower.
xDo not get off the windrower while the
header is in operation.
xStop windrower engine and remove key
before adjusting or removing plugged
material from the machine. A child or
even a pet could engage the drive.
xCheck for excessive vibration and
unusual noises. If there is any indication
of trouble, shut down and inspect the
machine. Follow proper shutdown
procedure:
- engage windrower brake
- turn off engine and remove key
- wait for all movement to stop
- dismount and engage lift cylinder stops
before inspecting raised machine.
xOperate only in daylight or good
artificial light.
(continued next page)

OPERATION
Form # 169089 13 Model Year - 2010
xKeep everyone several hundred feet
away from your operation. Ensure
bystanders are never in line with the
front or rear of the machine. Stones or
other foreign objects can be ejected
from either end with force.
xExtreme care must be exercised to
avoid injury from thrown objects. Do
not, under any circumstances, operate
the mower-conditioner when other
people are in the vicinity. Stones and
other objects can be thrown great
distances by the rotating cutting blades.
xThe cutterbar curtains are very
important to reduce the potential for
thrown objects. Always keep these
curtains down when operating the
mower-conditioner. Replace the
curtains if they should become worn or
damaged.
