1.1 Overview
The operator seat is compatible with all ‘92 through ‘96 model LT30, LT40, LT30HD,
LT40HD, LT60HD and LT70HD standard and super mills. The seat allows the operator to
be seated while traveling with the saw head. NOTE: The seat reduces maximum cutting
length by 25". The seat can be easily removed for full-size logs.
CAUTION! Seat capacity: 300 lb (136 kg). Overloading will
damage the feed system.
WARNING! Remove seat when not using with sawmill.
Unused seat creates possible pinch point with moving saw
carriage.
