This emergency lowering valve (see Figure 14) allows the
operator or service technician to lower the lift truck's mast
assembly if the electrical signal to the main control valve is
disrupted. See the section Load Handling, Emergency
Load Lowering in the Operating Procedures section.
Operator Protection Equipment
The LOAD BACKREST EXTENSION is installed to keep
loose parts of the load from falling back toward the operator.
It must be high enough, with vertical openings small enough,
to prevent the parts of the load from falling backwards. If a
load backrest extension that is different from the one installed
on your lift truck is required, contact your Yale lift truck dealer.
The OVERHEAD GUARD is intended to offer reasonable
protection to the operator from falling objects, but cannot
protect against every possible impact. Therefore, it must not
be considered a substitute for good judgment and care when
handling loads. Do not remove the overhead guard.
NOTE: The seat belt can be either black or red.
The SEAT BELT AND HIP RESTRAINT provide additional
means to help the operator keep the head and torso sub-
stantially within the confines of the lift truck frame and over-
head guard if a tipover occurs. This restraint system is
intended to reduce the risk of the head and torso being trap-
ped between the lift truck and the ground, but it cannot protect
the operator against all possible injury in a tipover. The hip
restraint will help the operator resist side movement. It is not
a substitute for the seat belt. Always fasten the seat belt.
This lift truck is equipped with one of the three seat belt con-
figurations.
• Seat belt with no operation interlock.
• Seat belt with operation interlock. Seat belt must be fas-
tened for lift truck to start or to travel.
• Seat belt with sequencing interlock. Operator must be in
the seat, then the seat belt fastened before lift truck will
operate. This seat belt is used with the Optional Operator
Presence System.
