Function Speed Tuning

All machine function speeds are determined by the
percentage of total ECM voltage output. The
speeds of the following machine functions may be
adjusted to compensate for wear in the hydraulic
pump and drive motors.
• Stowed drive speed
• High torque drive speed
• Raised drive speed
• Platform lift speed
For further information or assistance, consult the
Genie Industries Service Department.
Tip-over hazard. Do not adjust the
lift and/or drive speed higher than
specified in this procedure. Setting
drive speed greater than
specifications could cause the
machine to tip over resulting in
death or serious injury.
Tip-over hazard. This procedure
must only be performed by a
trained service professional.
Attempting this procedure without
the necessary skills will result in
death or serious injury.
