CAUTIONS
Contained in this section are cautions to be observed during 454647E Installation and Operation.
Wiring
All machine wiring has common ground connected to machine chassis and continuous through the power
supply, cord and cord plug. Make sure the receptacle for this plug has a good ground connection.
Safety and Comfort
Some ergonomic studies suggest that long periods of repetitive motion may be traced to certain types of
physical discomfort leading to possible injury. We have compiled specific instructions herewith to
minimize your chances of experiencing carpal tunnel syndrome (CTS), tendonitis, and tenosynovitis.
It is recommended that your work environment be comfortable for your work situation. A carefully
planned work environment can actually increase productivity. W
ESTBOND recommends that you adopt
the following steps for a healthy physical and mental approach to your work.
Exercises
Many motor oil-manufacturing companies often claim that your car engine is most subject to wear and
tear when you first start it up in the morning. This is due to the lack of oil on the metal bearing surfaces
offering protection when the car is first started. To a great extent, the same can be said for the tendons,
bones, and joints that form your body. In the early morning hours, your body tends to retain fluid from its
over night rest, and the first time these tendons and joints are put to use, there is often a feeling of
stiffness and tightness, and when utilized in an abrupt fashion, can often lead to inflammation and at
times injury.
Therefore, it is considered appropriate if not mandatory for most people engaged in physical activities
such as sports or heavy labor, such as construction, to perform a variety of warm-up exercises before
beginning their job. We have found the same philosophies and many of these same exercises just as
beneficial for those individuals who are placed in a seated position for long periods of time where they
utilize primarily their upper extremities, and most importantly, their hands and wrists.
We are therefore, suggesting the following gentle warm-up program to be done by you before leaving for
work. Begin by gently tilting your head both to the right and left side, to the point of comfortable tension.
Next, tilt your head forward and backward, and lastly, turn your head both to the left and to the right.
Each of these positions is taken to the end of their natural range of motion and held for a brief period of
time. Do not take any of these movements beyond the point of comfort.
Next, for the shoulders, perform a series of simple, slow, shoulder circles in both a forward and backward
direction. Five to ten repetitions in each direction should be enough to warm up the shoulder
musculature.
Next, while standing, lift your arms laterally out to the side, away from your body and over your head.
Repeat this motion five times. For added benefit, make large, wrist circles with your hands while your
arms are overhead.
Lastly, and possibly most importantly, it is important that you carefully flex and extend your wrist prior to
beginning your workday. Using the opposite hand to bend the wrist downward does this. This is best
done with the arm in a forward position with the elbow straight. To assist in wrist extension, lift your wrist
up, using the palm of the opposite hand, pressing against the fingers to assist in lifting the wrist. These
stretches are done only to the point of comfortable tension and are repeated with both hands.
These basic exercises will get you off to a good start in the morning and allow your drive to work to be
more comfortable and less likely to increase the tension and tightness in your upper back, shoulders and
hands.

CAUTIONS
Work Station Exercises
Sometimes it is only when we take breaks at work that we realize how stiff or uncomfortable we have
become from working in a seated position. When we concentrate intensely on our work, these types of
discomfort often go unnoticed and therefore, we recommend the following exercise program.
After Work Cool-Down Exercises
When you return home from work, it is helpful to relax the hard working muscle groups by repeating your
morning exercise program. Many people also find that taking a gentle walk or similar forms of activity
provide a nice change of pace from the immobile routine encountered at work. Please check with your
physician, however, before beginning any type of exercise program.
Take periodic breaks several times during the work schedule. Gently press your hands against a table,
stretch, and hold for several seconds. Stretch and massage your fingers, hands, wrists and forearms
throughout the day. Shake your hands and fingers to relieve any tension and to promote blood flow.
Rotate your shoulders forward and backward in a full circle several times daily. Try to use different
muscle groups throughout the day, i.e. if sitting for prolonged periods, get up and walk around several
times a day.
If you experience pain any time during the operation of your W
ESTBOND machine, consult a qualified
health professional.
Chair And Table Top
When evaluating your workstation, pay particular attention to those surfaces that come in contact with
your wrist and forearms. Sharp edges or hard surfaces should be modified to form a work surface that is
comfortable at the point of contact. Reshaping corners and applying a more comfortable softer surface in
the work area can be extremely helpful.
The chair should be comfortable and provide firm support to the lumbar region (lower back). The chair
should be adjustable in height so that your forearms form approximate right angles with the upper arms
while hands rest upon the tabletop. Next, ensure feet rest flat on the floor and, if not, use a footrest that is
high enough so that your thighs are reasonably parallel to the floor while seated. During the course of
operating your W
ESTBOND machine, maintain this recommended posture—any slouching puts
unnecessary strain on your back and may weaken muscles over time.
Microscope / Monitor
It is important to look away from the microscope eyepieces and/or monitor frequently. Try to focus on an
object about 20 feet away from several seconds. Eyepieces of the microscope should be clean and
microscope should be frequently calibrated for parfocal viewing.

CAUTIONS
Micromanipulator
The hand controls on your WESTBOND machine have been designed for minimal exertion of the hand
and fingers. The position of the control knob is purposely set to coincide with a natural rest position of the
hand (fetal position). During operation, the operator should rest his/her hand, wrist, and forearm on the
tabletop so that the thumb, index and middle fingers gently grip the manipulator knob. With the work
piece centered in the microscope, and the tool centered to the optics, usual movement or excursion of the
manipulator is usually within plus or minus one-half inch, which is well within natural flexure of the thumb
and fingers gripping the control knob. The force required to move the mechanism is somewhat equivalent
to pushing a pencil while writing. Following the recommendations set forth in “Exercises” above vastly
relieves any perception of muscle fatigue.
The last key point; all these guidelines should be applied to your home work station and home activities,
particularly home computers. They should also be applied to video games and your recreational
television viewing.
After a long day at work, your body does not need more of the same type of activity when you return
home. Remember, diversity of physical activity may well be the simplest and most meaningful
recommendation to avoid repetitive stress syndrome such as carpal tunnel syndrome.
