SAFETY PRECAUTIONS
Roll Over Protective Structures
(ROPS)
TYM Tractors are equipped with a frame for
the protection of operators.
In the case of cab tractors the frame is incor-
porated in the cab structure.
The objective of the frame or cab structure is
to protect the operator in the event of a roll
over and they are designed to support
the entire weight of the tractor in that event.
Each TYM ROPS frame or cab structure is
designed and has been tested to meet industry
and or Government standards.
Included in these tests were all mounting bas-
es and bolts or other fasteners.
On some models the ROPS frame has a
fold down feature, which can be used to
enter low buildings etc Take care when
lowering
the upper section of the ROPS frame and
take extreme care while driving the trac-
tor with the ROPS frame lowered.
Do not wear the seat belt with the ROPS
lowered and please remember that the
fold down facility is for special circum-
stances
only and must not be lowered for general
use.
Use of the tractor with the ROPS low-
ered can cause fatal injuries.
As the ROPS frame or cab together with the
seat belt was designed to meet certain stan-
dards, they must be maintained in good
order and condition. To achieve this objective,
both the structure and the seat belt should be
inspected on a regular basis (every
time the tractor is serviced)
In the event that the seat belt is damaged or
frayed, it should be replaced and in the event
that the ROPS frame or any part of the
mounting structure is damaged or cracked,
the faulty component must be replaced with a
new unit. Such a unit must meet all of
the test criteria of the original unit .Fitment of
an inferior item or items affects the certica-
tion of the entire ROPS structure and
the effectiveness of the structure in the event
of an accident. Drilling or welding of the
ROPS structure is forbidden.
(ROPS) Roll Over Protective Structures
• For ROPS frames to be effective
and protect the operator, the seat
belt provided must be worn in order
to keep operators within the ROPS
protected area in the event of a roll
over. Failure to use the seat belt can
still cause serious injury or death.
