PREFACE
BEFORE OPERATION
The primary responsibility for safety with equipment
falls to the operator. Make sure the equipment is op-
erated only by trained individuals that have read and
understand this manual. If there is any portion of this
manual or function you do not understand, contact
your local authorized dealer or manufacturer to ob-
tain further assistance. Keep this manual available for
reference. Provide this manual to any new owners and/
or operators.
SERVICE
Use only manufacturer replacement parts. Substitute
parts may not meet the required standards. Record the
model and serial number of your unit on the cover of
this manual. The parts department needs this informa-
tion to ensure that you receive the correct parts.
SOUND AND VIBRATION
Sound pressure levels and vibration data for this at-
tachment are inuenced by many different parameters;
some items are listed below (not inclusive):
• prime mover type, age, condition, with or with-
out cab enclosure and conguration
• operator training, behavior, stress level
• job site organization, working material condition,
environment
Based on the uncertainty of the prime mover, operator,
and job site, it is impossible to get precise machine and
operator sound pressure levels, or vibration levels for
this attachment.
GENERAL INFORMATION
This product was carefully designed and manufactured.
Only minor maintenance (such as cleaning and lubricat-
ing) is required to keep it in top working condition. Be
sure to observe all maintenance procedures and safety
precautions in this manual and on any safety decals
located on the product and on any equipment on which
the attachment is mounted.
WARNING!
Never let anyone operate this unit without
reading the “Safety Precautions” and “Oper-
ating Instructions” sections of this manual. Always
choose hard, level ground to park the vehicle on and set
the brake so the unit cannot roll.
NOTE: The illustrations and data used in this man-
ual were current (according to the information
available to us) at the time of printing, however, we re-
serve the right to redesign and change the attachment
as may be necessary without notication.
SAFETY ALERT &
WARNING SYMBOLS
These are the “Safety Alert & Warning
Symbols” used by this industry. These
symbols are used to warn of possible
injury. Be sure to read all warnings
carefully. They are included for your safety

Unless noted
otherwise, right
and left sides are
determined from
the operator’s control position
when facing the attachment.

your attention to instructions involving your personal
safety or the safety of others. Failure to follow these
instructions can result in injury or death.
SAFETY DEFINITIONS
The purpose of safety symbols is to attract your
attention to possible dangers. The safety symbols,
and their explanations, deserve your careful attention
and understanding. The safety warnings do not by
themselves eliminate any danger. The instructions
or warnings they give are not substitutes for proper
accident prevention measures.
DANGER
Danger indicates a hazardous situation which, if
not avoided, will result in death or serious injury.
WARNING
Warning indicates a hazardous situation which,
if not avoided, could result in death or serious
injury.

hydraulic hoses, read your prime movers operator’s manual for
detailed instructions on connecting and disconnecting hydraulic
hoses or ttings.
• Keep unprotected body parts, such as face, eyes, and arms
as far away as possible from a suspected leak. Flesh injected
with hydraulic uid may develop gangrene or other perma-
nent disabilities.
• If injured by injected uid, see a doctor at once. If your doc-
tor is not familiar with this type of injury, ask him to research
immediately to determine proper treatment.
• Wear safety glasses, protective clothing, and use a sound
piece of cardboard or wood when searching for hydraulic
leaks.
DO NOT USE YOUR HANDS!

EQUIPMENT SAFETY PRECAUTIONS
REMOVE PAINT BEFORE
WELDING OR HEATING
Hazardous fumes/dust can be generated when
paint is heated by welding, soldering or using a
torch. Do all work outside or in a well-ventilated area
and dispose of paint and solvent properly. Remove
paint before welding or heating.
When sanding or grinding paint, avoid breathing the
dust. Wear an approved respirator. If you use solvent
or paint stripper, remove stripper with soap and water
before welding. Remove solvent or paint stripper
containers and other ammable material from area.
Allow fumes to disperse at least 15 minutes before
welding or heating.
END OF LIFE DISPOSAL
At the completion of the useful life of the unit,
drain all uids and dismantle by separating the
different materials (rubber, steel, plastic, etc.). Follow
all federal, state and local regulations for recycling and
disposal of the uid and components.
KNOW WHERE UTILITIES ARE
Observe overhead electrical and other utility
lines. Be sure equipment will clear them. When
digging, call your local utilities for location of buried
utility lines, gas, water, and sewer, as well as any other
hazard you may encounter.
ROTATING OBJECTS
Never allow anyone to reach into, kick into,
or otherwise come in contact with a rotating
auger or with a non-rotating clogged auger. The auger
can crush and/or dismember. Keep everyone clear of
the auger until the prime mover engine is off and the
hydraulic pressure has been relieved.
Never allow anyone to reach into the chute, force
objects (i.e. bars, poles, etc.) down the chute, kick into
the fan, or otherwise come in contact with a rotating
fan or with a non-rotating clogged fan. The fan can
throw objects at a lethal speed and can dismember.
Keep everyone clear of the fan until the prime mover
engine is off and the hydraulic pressure has been
relieved.
AVOID PINCH POINTS
Avoid pinch points and be aware of rotating
parts when manually turning the fan or auger.

LIFT POINTS
Lift Points are identied in the image below. Lifting
at other points is unsafe and can damage attach-
ment. Do not attach lifting accessories around
cylinders or in any way that may damage hoses or
hydraulic components.
USE LIFTING ACCESSORIES
(CHAINS, SLINGS, ROPES, SHACK-
LES AND ETC.) THAT ARE CAPABLE OF
SUPPORTING THE SIZE AND WEIGHT
OF YOUR ATTACHMENT. Secure all lifting
accessories in such a way to prevent un-
intended disengagement. Failure to do so
could result in the attachment falling and
causing serious personal injury or death.
• Attach lifting accessories to unit at recom-
mended lifting points.
• Bring lifting accessories together to a central
lifting point.
• Lift gradually, maintaining the equilibrium of
the unit.
