2.2 EQUIPMENT SAFETY GUIDELINES
1. Safety of the operator and bystanders is one
of the main concerns in designing and de-
veloping equipment. 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

children be allowed to work with this
equipment. Do not allow persons to use or
assemble this unit until they have read this
manual and have developed a thorough
understanding of the safety precautions and
of how it works. Review the safety
instructions with all users annually.
6. This equipment is dangerous to children and
persons unfamiliar with its operation. The
operator should be a responsible, properly
trained and physically able person familiar
with machinery and trained in this equipment's
operations. If the elderly are assisting with work,
their physical limitations need to be recognized
and accommodated.
7. Never exceed the limits of a piece of machin-
ery. If its ability to do a job, or to do so safely, is
in question - DON'T TRY IT.

2.3 SAFETY TRAINING
1. Safety is a primary concern in the design and
manufacture of our products. Unfortunately,
our efforts 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 configuration of
equipment, hazard control and accident pre-
vention are dependent upon the awareness,
concern, 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 opera-
tor." We ask you to be that
kind of an operator. It is the
operator's responsibility to read and under-
stand ALL Safety and Using 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
before assembly or using, to acquaint
yourself with the machine. If this machine is
used by any person other than yourself, or is
loaned or rented, it is the machine
owner's responsibility to make certain that
the operator, prior to using:
a. Reads and understands the operator's
manuals.
b. Is instructed in safe and proper use.
5. Know your controls and how to stop tractor
and machine quickly in an emergency. Read
this manual and the one provided with tractor.
6. Train all new personnel and review instruc-
tions frequently with existing workers. Be
certain only a properly trained and physically
able person will use the machinery. A person
who has not read and understood all using
and safety instructions is not qualified to use the
machine. An untrained operator exposes
himself and bystanders to possible serious in-
jury or death. If the elderly are assisting with the
work, their physical limitations need to be
recognized and accommodated.
2.4 SAFETY SIGNS
1. Keep safety signs clean and legible at all
times.
2. Replace safety signs that are missing or have
become 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 replace-
ment parts.
5. Safety signs are available from Betst
Products, llc
How to Install Safety Signs:
• Be sure that the installation area is clean and
dry.
• Be sure temperature is above 50°F (10°C).
• Determine exact position before you remove
the backing paper.
• Remove the smallest portion of the split back-
ing paper.
• Align the sign over the specified area and
carefully press the small portion with the ex-
posed sticky backing in place.
• Slowly peel back the remaining paper and
carefully smooth the remaining portion of the
sign in place.

2.5 PREPARATION
1. Never use the machine until you have read
and completely understand this manual, the
tractor Operator's Manual and each of the
Safety Messages found on the safety signs on
the tractor and machine.
2. Personal pro-
tection equip-
ment including
hard hat, safety
glasses, safety
shoes, and
gloves are rec-
ommended dur-
ing assembly,
installation, operation, adjustment, maintain-
ing, repairing, removal, cleaning, or moving
the unit. Do not allow long hair, loose fitting
clothing or jewery to be around equipment.
3. PROLONGED EXPOSURE
TO LOUD NOISE MAY
CAUSE PERMANENT
HEARING LOSS!
Power equipment with or
without 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 ba-
sis 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 stones, branches or
hidden obstacles that might be hooked or
snagged, causing injury or damage.
5. Use only in daylight or good artificial light.
6. Be sure machine is properly mounted, adjust-
ed and in good operating condition.
7. Ensure that all safety shielding and safety
signs are properly installed and in good condi-
tion.
2.6 MAINTENANCE SAFETY
1. Good maintenance is your responsibility. Poor
maintenance is an invitation to trouble.
2. Follow good shop practices.
- Keep service
area clean and
dry.
- Be sure electrical
outlets and tools
are properly
grounded.

5.5 DRIVELINE DIMENSION
A PTO driveline is supplied with the machine. To ac-
company the variety of 3 point hitch geometry available
today, the driveline can be too long for most machines
or too short for others. It is very important that the drive-
line be free to telescope but not to bottom out when
going through its working range. If the driveline bottoms
out, the bearings on both the machine and tractor PTO
shaft will be overloaded and fail in a short time.
1. To determine the proper length of the driveline,
follow this procedure:
a. Clear the area of bystanders, especially small
children.
b. Attach the chipper to the tractor but do not
attach the driveline.
c. Raise the machine until the input shaft is level with
the tractor PTO shaft.
d. Measure the dimension between the locking
grooves on the tractor PTO shaft and the machine
input shaft.
e. Measure the same dimensions on the compressed
driveline.
f. If the compressed driveline dimension exceeds the
machine dimension, the driveline will have to be cut.
2. When cutting the driveline, follow this procedure:
a. Subtract the machine dimension (A) from the uncut
driveline dimension (B) or (B-A). This dimension
determines how much too long the driveline is.
DRIVELINE DIMENSIONS
