Safety Devices
This unit has two kinds of safety devices. Guard fences
protect each side of the unit. These are designed to
keep everyone away from the moving parts of the unit
while it is operating. These guards should always be
in place when the unit is operating normally.
There may be some cases where you will want to do
maintenance work with the safety guards removed. You
should be especially careful during these procedures.
As the load enclosure moves up and down, “pinch
points” are created where the moving parts meet. If you
are standing too close to the load enclosure when it is
moving, your arm or leg may be caught in the moving
parts, and you may be hurt. Stay away from the pinch
points when the safety guards are removed and the load
enclosure is moving. Always replace the safety guards
as soon as you are done with the maintenance work.
The unit also includes three photo-eye systems.
Each photo-eye system includes a light source on one
side of the unit, and a reflector on the other side. If
any of the light beams is broken, the unit will not start,
and the load enclosure will not move. This helps to
ensure that everyone is out of the way before the load
enclosure moves.
Before using the unit, please be sure that the guards
are in place, and that the photo-eye system is work-
ing. If the guards are missing, or the photo-eyes are
not working, turn off the machine right away and call
a supervisor. Never operate the unit without these
important safety features.
Figure 3 shows the positions of the warning labels
on the unit. These labels have been included for your
safety. If you find that the labels are worn or missing,
or have been painted over, ask Maintenance to replace
the labels before you use the unit.
You should never operate the unit with the safety guards removed. This machine is equipped
with an external power unit, which is mounted a short distance away from the machine.
