1.9 LIMIT SWITCHES
The machines are equipped with the following limit
switches:
Tilt Alarm (optional 1-1/2° or 2°)
Illuminates a light on the platform and sounds an alarm
when the machine is 11/2° or 2°, depending on which tilt
the machine is equipped with, out of level in any direction.
High Drive Cut-Out
High drive speed is cut out when the platform is raised
above the stowed position.
Drive Cut-Out (Models 2033E3, 2046E3,
2646E3, and 2658E3 with Powered Deck
Extension)
On these machines, the Drive function is cut out when the
powered deck extension is extended with the platform
raised above the stowed position.
Electronic Armguard Switch
Lift down is cut out when the gap between the arms is in
the range of 5 in. to 8 in. (13 cm. to 20 cm.). This will cut
out lift down and sound the platform alarm for 1/2 second
on, 1/2 second off, and repeat this for three seconds. After
three seconds the operator must re-select the lift function
and continue lifting down.
Temperature Switch
This switch prevents the high drive function from engag-
ing when the oil temperature is very cold. The machine will
remain in low drive until the oil has warmed and will then
automatically move up to high drive.
Overload Protection (Japanese Specification
Only)
When the platform is loaded to 120% of its rated capacity,
the lift up and drive functions are cut out and the platform
alarm (if equipped) is sounded for two seconds on, two
seconds off while the operator tries to activate either lift up
or drive. Remove weight from the platform to restore lift up
and drive functions operation and to silence the alarm (if
equipped).
