Seat Belt
Before fitting the seat belt, check that there is no problem in the belt mount bracket or mounting belt. If it is worn or damaged,
replace the seat belt.
Even if there are no signs of damage, replace belts in accordance with the following schedule:
5 years after the date of seat belt manufacture, or every 3 years after the start of actual usage, whichever date comes first.
Always wear the seat belt during operations.
Fit the seat belt so that it is not twisted.
REMARK
The date of seat belt manufacture attached to the seat belt is the start of the 5-year period. It is not the start of the
3-year period of actual usage.
