Precautions When Using ROPS SAFETY Never modify, weld, cut, or drill on any part of a ROPS structure. Doing so may weaken the structure which could lead to possible failure in a rollover situation. The operator’s compartment is equipped with a Roll Over Protective Structure (ROPS) to protect the operator. ROPS is designed to support the load if the machine rolls over and also to absorb the impact of the energy. The ROPS fulfills all the regulations and standards for all countries. If the machine weight (mass) exceeds the certified value (shown on the Roll Over Protective Structure (ROPS) certification plate), ROPS will not be able to fulfill its function.
Do not increase machine weight beyond the certified value by modifying the machine or by installing attachments to the machine. If the function of the protective equipment is impeded, the protective equipment will not be able to protect the operator and the operator may suffer injury or death. Always observe the following rules: Do not remove the protective structure and carry out operations without it. If the protective structure is welded, or holes are drilled in it, or if it is modified in any other way, its strength may decrease. Never drill, cut, weld on, or modify the ROPS structure.
If the protective structure is damaged or deformed by falling objects or by rolling over, its strength will be reduced and it will not be able to fulfill its function properly. If the ROPS structure is damaged in any way, replace it immediately. Do not make repairs to the ROPS structure itself. Even if the protective structure is installed, always fasten your seat belt properly when operating the machine. If you do not fasten your seat belt properly, it cannot provide full protection. See “Seat Belt Inspection” on page 1-11.
