PROBLEM

Show/hide table

The secondary escape hatches and skylights needs to be reworked on certain 2390, 2491, 511, 521, 521B, 522, 522B, 532, 541, 541 Series 2, 552, and 552 Series 2 Track Feller Bunchers. The existing secondary escape hatch and skylight seals could become semi-bonded to the painted hatch surface, increasing the amount of force required to open the hatch or skylight. This may, in conjunction with other factors or circumstances, result in a risk of personal injury or death.
