Test the Key Switches - ALC1000
Models
Genie specifications require that this procedure be
performed annually.
Proper key switch action and response is essential
to safe machine operation. Failure of either key
switch to function properly could cause a
hazardous operating situation.
This maintenance procedure applies to the
following models:
S-100,
S-100HD, S-105, S-120,
S-120HD, S-125, SX-105XC, SX-125XC, SX-
135XC, SX-150, SX-180, Z-80/60, Z-135/70 and
ZX-135/70.
There are two key switches on the machine - the
Main key switch and the Bypass/Recovery key
switch.
The Main key switch controls machine operation
from the ground or platform controls.
When the Bypass/Recovery key switch is turned to
the bypass position, the primary boom can be
elevated with the axles retracted (if equipped with
retractable axles). This feature of the machine is
especially helpful for storage purposes or when
loading the machine for transport.
When the Bypass/Recovery key switch is turned
and held to the recovery position, the emergency
power unit turns on and starts a sequence to lower
the platform. This feature of the machine is
especially helpful if the operator in the platform
cannot lower the boom, if the platform controls
become inoperative or for returning the machine to
a safe position when the safety switches have
been tripped.
