2.2 EQUIPMENT SAFETY GUIDELINES
1. Safety of the operator and bystanders is one of
the main concerns in designing and developing
a machine. However, every year many accidents
occur which could have been avoided by a few
seconds of thought and a more careful approach
to handling equipment. You, the operator, can
avoid many accidents by observing the following
precautions in this section. To avoid personal in-
jury or death, study the following precautions and
insist those working with you, or for you, follow
them.
2. In order to provide a better view, certain photo-
graphs or illustrations in this manual may show an
assembly with a safety shield removed. However,
equipment should never be operated in this con-
dition. Keep all shields in place. If shield removal
becomes necessary for repairs, replace the shield
prior to use.
3. Replace any safety sign or instruction sign that is
not readable or is missing. Location of such safe-
ty signs is indicated in this manual.

eorts to provide safe equipment can be wiped
out by a single careless act of an operator or
bystander.
2. In addition to the design and conguration of
equipment, hazard control and accident preven-
tion are dependent upon the awareness, con-
cern, prudence and proper training of personnel
involved in the operation, transport, maintenance
and storage of this equipment.
3. It has been said, "The best
safety feature is an informed,
careful operator." We ask you
to be that kind of an operator.
It is the operator's responsibility to read and un-
derstand ALL Safety and Operating instructions
in the manual and to follow these. Accidents can
be avoided.
4. Working with unfamiliar equipment can lead
to careless injuries. Read this manual, and the
manual for your auxiliary equipment, before
assembly or operating, to acquaint yourself
with the machines. If this machine is used by
any person other than yourself. It is the ma-
chine owner's responsibility to make certain
that the operator, prior to operating:
a. Reads and understands the operator's
manuals.
b. Is instructed in safe and proper use.
5. Know your controls and how to stop pilers, sting-
ers, Screen Sizers, conveyors and any other aux-
iliary equipment quickly in an emergency. Read
this manual and the one provided with your other
equipment.
6. Train all new personnel and review instructions
frequently with existing workers. Be certain only
a properly trained and physically able person will
operate the machinery. A person who has not
read and understood all operating and safety in-
structions is not qualied to operate the machine.
An untrained operator exposes himself and by-
standers to possible serious injury or death.
If the elderly are assisting with farm work, their
physical limitations need to be recognized and
accommodated.
2.5 SAFETY SIGNS
1. Keep safety signs clean and legible at all times.
2. Replace safety signs that are missing or have be-
come illegible.
3. Replaced parts that displayed a safety sign
should also display the current sign.
4. Safety signs displayed in Section 3 each have a
part number in the lower right-hand corner. Use
this part number when ordering replacement
parts.
5. Safety signs are available from your authorized
Distributor or Dealer Parts Department or the
factory.
How to Install Safety Signs:
• Be sure that the installation area is clean and dry.
• Be sure temperature is above 50°F (10°C).

2.6 PREPARATION
1. Never operate the Belted Screen Sizer and aux-
iliary equipment until you have read and com-
pletely understand this manual, the auxiliary
equipment Operator's Manual, and each of the
Safety Messages found on the safety signs on the
Screen Sizer and auxiliary equipment.
2. Personal protec-
tion equipment
including hard
hat, safety glass-
es, safety shoes,
and gloves are
recommended
during assembly,
installation, op-
eration, adjust-
ment, maintaining, repairing, removal, or moving
the implement. Do not allow long hair, loose tting
clothing or jewelry to be around equipment.
3. PROLONGED EXPOSURE
TO LOUD NOISE MAY CAUSE
PERMANENT HEARING LOSS!
Motors or equipment attached
can often be noisy enough to
cause permanent, partial hearing
loss. We recommend that you
wear hearing protection on a full-time basis if the
noise in the Operator's position exceeds 80db.
Noise over 85db on a long-term basis can cause
severe hearing loss. Noise over 90db adjacent to
the Operator over a long-term basis may cause
permanent, total hearing loss. NOTE: Hearing
loss from loud noise (from tractors, chain saws,
radios, and other such sources close to the ear) is
cumulative over a lifetime without hope of natural
recovery.
4. Clear working area of debris, trash or hidden ob-
stacles that might be hooked or snagged, caus-
ing injury, damage or tripping.
