SECTION 4. MACHINE OPERATION
4.1 DESCRIPTION
General Description of the Functions and
Components.
The normal location to operate the machine is on the plat-
form. However, the control box can be disconnected from
the platform location and plugged in (in emergencies) at the
distribution terminal inside the valve compartment of the
machine.
Situated on the control panel is an emergency STOP-button,
which is activated when being pressed and cuts out all func-
tions, except emergency lowering.
The machine is equipped with a horn. The horn is activated
by a push-button located on the control panel. The machine
is also equipped with an audible alarm, which is automati-
cally activated, when the machine driven.
The allowable operation of the machine is within the follow-
ing certain tolerance limits, which are monitored and con-
trolled via limit switches:
Tilt Switch
The machine cannot be elevated or driven while elevated if it
is on a slope greater than 3°. The grade of the slope is mea-
sured by a tilt switch, which cuts off the lift up, and elevated
drive function. At this point lowering is still possible. The tilt
switch is enabled when the platform is raised by approx. 1 m
(3.2 ft).
The tilt switch cuts out lifting, driving, and steering once the
machine reaches a tilt angle (slope) beyond 3° and the plat-
form is raised by 1 m (3.2 ft). At this point, lowering is the
only function possible.
