Introduction
This manual contains safety information, set-up instructions, operating and maintenance procedures, and parts
informationforthe Model HC10 HayConditioner. Thishayconditioner,whenteamedwith an M-SeriesSelf-Propelled
Windrowerpower unitand a D-Series Draper Header,will cut and lay crop into uniform, fluffy windrows. Conditioning
or crimping the cut hay allows moisture release for quicker drying and earlier processing.
CAREFULLY READ ALL THE MATERIALPROVIDEDBEFORE ATTEMPTINGTOUNLOAD, ASSEMBLE, OR USE
THE MACHINE.
Use this manual as your first source of information about the machine. If you follow the instructions given in this
manual, your hay conditioner will work well for many years. Use this manual in conjunction with your M-Series
Self-Propelled Windrower and D-Series Draper Header manuals.
Use the Table of Contents to guide you to specific topics. Review the Table of Contents to familiarize yourself with
how the material is organized.
Keep this manual handy for frequent reference and to pass on to new Operators or Owners. Call your Dealer if you
need assistance, information, or additional copies of this manual.

1.3 General Sa
fety
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:
– A hard hat
– Protective footwear with slip resistant soles
– Protective glasses or goggles
– Heavy gloves
Figure 1.2
– Wet weather gear
– A respirator or filter mask
– Hearing protection
Be aware that exposure to loud noise can cause
impairment or loss of hearing. Wearing suitable
hearing protection devices such as ear muffs or ear
plugs. These will help protect against objectionable
or loud noises.
•Provideafirst aid kit for use in case of emergencies.
•Keepafire extinguisher on the machine. Be sure the fire
extinguisher is properly maintained. Be familiar with its
proper use.
• Keep young c hildren away from the machinery at
all times.
• Beaware that accidents often happen when theOperator
istiredorinahurrytogetfinished. Takethetimeto
consider the safest way. Never ignore warning signs
of fatigue.

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.
• 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
modificationsmayimpair machine functionand/orsafety.
It may also shorten the machine’s life.
Figure 1.5
• Stop e ngine 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 w ith 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.

WARNING
• Wear safety glasses when working near
batteries.
• Do not tip batteries more than 45° to avoid
electrolyte loss.
• Battery electrolyte causes severe burns. Avoid
contact with skin, eyes, or clothing.
• Electrolyte splashed into the eyes is extremely
dangerous. Should this occur, force the eye
open, and floodwithcool,cleanwaterforfive
minutes. Call a doctor immediately.
• If electrolyte is spilled or splashed on clothing
or the body, neutralize it immediately with a
solution of baking soda and water, then rinse
with clear water.
Figure 1.18
WARNING
• To avoid injury from spark or short circuit,
disconnect battery ground cable before
servicing and part of electrical system.
• Do not operate the engine with alternator or
battery disconnected. With battery cables
disconnected and engine running, a high
voltage can be built up if terminals t ouch the
frame. Anyone touching the frame under these
conditions would be severely shocked.
• When working around storage batteries,
remember that all of the exposed metal parts
are live. Never lay a metal object across the
terminals because a spark or short circuit will
result.
• Keep batteries out of reach of children.

1.8 Welding Precautio n
High currents and voltage spikes associated with welding can cause damage to electronic components. Before
welding on any part of the windrower or an attached header, disconnect all electronic module harness connections
as well as the battery cables. Refer to your technical manual or MacDon Dealer for proper procedures.

ety
WARNING
Do not use aerosol types of starting aids such as ether. Such use could result in an explosion and
personal injury.
CAUTION
• In the initial start-up of a new, serviced, or repaired engine always make provision to shut the
engine off, in order to stop an over-speed. This may be accomplished by shutting off the air and/or
fuel supply to the engine. Over-speed shut down should occur automatically for engines that are
controlled electronically.
• Do not bypass or disable the automatic shutoff circuits. The circuits are provided in order to help
prevent personal injury. The circuits are also provided in order to help prevent engine damage. See
the technical manual for repairs and adjustments.
• Inspect the engine for potential hazards.
• Before starting the engine, ensure that no one is on, underneath, or close to the engine. Ensure that
theareaisfreeofpersonnel.
• Allprotective guards and all protective covers m ust be installed if the engine must be started in order
to perform service procedures.
• To help prevent an accident that is caused by parts in rotation, work around the parts carefully.
• If a warning tag is attached to the engine start switch or to the controls, do NOT start the engine
or move the controls. Consult with the person who attached the warning tag before the engine is
started.
• Start the engine from the operator’s compartment. Always start the engine according to the
procedure that is described in the Engine Starting section of the operator’s manual. Knowing
the correct procedure will help to prevent major damage to the engine components and prevent
personal injury.
• To ensure that the jacket water heater (if equipped) and/or the lube oil heater (if equipped) is working
correctly, check the water temperature gauge and/or the oil temperature gauge during the heater
operation. Engine exhaust contains products of combustion which can be harmful to your health.
Always start the engine and operate the engine in a well ventilated area. If the engine is started in an
enclosed area, vent the engine exhaust to the outside.
NOTE: The engi
cold con
equipp
ne may be equipped with a device for cold starting. If the engine will be operated in very
ditions, then an additional cold starting aid may be required. Normally, the engine will be
ed with the correct type of starting aid for your region of operation.
1.9.1 High Pressure Rails
CAUTION
Contact with high pressure fuel may cause fluid penetration and burn hazards. High pressure fuel spray
may cause a fire hazard. Failure to follow these inspection, maintenance and service instructions may
cause personal injury or death.

2.1.4 Flare-Type Hydraulic Fittings
1. Check flare and flare seat for defects that might
cause leakage.
2. Align tube with fitting before tightening.

3. Lubricate connection and hand-tighten swivel nut
until snug.
4. To prevent twisting the tube(s), use two wrenches.
Place one wrench on the connector body and with the
second, tighten the swivel nut to the torque shown.
