Test the Drive Speed - Raised
Position
Genie specifications require that this procedure be
performed quarterly.
Proper drive function is essential to safe machine
operation. The drive function should respond
quickly and smoothly to operator control. Drive
performance should also be free of hesitation,
jerking and unusual noise over the entire
proportionally controlled speed range.
1
Create start and finish lines by marking two
lines on the ground 40 feet / 12.2 m apart.
GS-30, GS-32, GS-46, GS-47: Raise the
