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
section. To avoid personal injury 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
photographs or illustrations in this manual
may show an assembly with a safety shield
removed. However, equipment should never
be used in this condition. 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 safety signs is indicated in this manual.
4. Never use alcoholic beverages or drugs which
can hinder alertness or coordination while us-
ing this equipment. Consult your doctor about
using this machine while taking prescription
medications.
5. Under no circumstances should young
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.
8. Do not modify the equipment in any way. Un-
authorized modication may result in serious
injury or death and may impair the function
and life of the equipment.
9. In addition to the design and conguration of
this implement, including Safety Signs and
Safety Equipment, hazard control and ac-
cident prevention are dependent upon the
awareness, concern, prudence, and proper
training of personnel involved in the operation,
transport, maintenance, and storage of the

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 conguration 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 responsibil-
ity 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,
engine and machine quickly in an emergency.
Read this manual and the one provided with
your engine.
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 qualied 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

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 articial 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.

4.4 PRE-OPERATION CHECKLIST
Efcient and safe operation of the Wallenstein Log
Grapple Trailer requires that each operator reads
and understands the using procedures and all re-
lated safety precautions outlined in this section. A
pre-operation checklist is provided for the opera-
tor. It is important for both the personal safety and
maintaining good mechanical condition that this
checklist is followed.
Before operating Trailer and each time thereafter,
the following areas should be checked off:
1. Lubricate the machine per the schedule out-
line in the Maintenance Section.
2. Check that all boom pivot points move freely.
3. Check that the grapple and pivot move freely.
4. Check for leaks in the hydraulic system.
Tighten leaking ttings. Repair or replace any
damaged components.
5. Torque all fasteners and hardware.
6. Check uid levels in the engine and hydraulic
reservoir. Top up as required.
7. Check for entangled material. Remove all
entangled material before resuming work.
8. Check tire pressure. Inate as required.
9. Make sure that all guards and shields are in
place, secured and functioning as designed.

4.5 CONTROLS
Before starting to work, all operators should
familiarize themselves with the location and
function of controls.
A. Gas Engine:
Always read the engine Operator's manual
supplied with the machine for detailed pro-
cedures.
a. Ignition Switch (Manual Start):
This rotary switch controls the electrical
power to the engine electrical system.
Turn the switch clockwise to turn the
electrical system ON and the engine will
run. Turn counter-clockwise to stop the
engine.
b. Fuel Shut-Off Valve:
Each engine is equipped with a valve
between the fuel tank and the carburator.
Slide the fuel valve toward the block to
turn ON and away to turn OFF. Turn the
fuel OFF before transporting.
c. Throttle:
This lever controls the engine RPM.
Move the lever laterally to increase or
decrease the RPM. Always run at maxi-
mum throttle while operating.
d. Choke:
The choke controls the fuel/air mixture to
the engine. Close the choke when start-
ing if the engine is cold. Open the choke
as the engine warms. Always open the
choke fully during operation.
e. Starting Rope:
This retracting rope and T-bar is used
to turn the engine over before starting.
