Limit Switch Checks

Check that the following limit switches function properly by
attempting to exceed the preset limits.

1. Lowered Position Limit Switch - Outriggers cannot be

deployed beyond the height of 9.8 ft (3m).

2. Limit Switches for Drive Mode

a. High Drive Speed Limit Switch - high drive speed is

possible up to a platform height of 12.14 ft (3.7 m).
When the platform exceeds this limit, only low drive
speed is possible.

b. Maximum Drive Height/Maximum Height without

Outriggers Limit Switch - The driving function is per-
mitted up to a platform height of 65 ft (20 m). Once
the limit is exceeded driving will be disabled. The
lifting function, without the outriggers deployed, is
only permitted up to a platform height of 65 ft (20 m)
as well.

3. Maximum Height Limit Switch - The Maximum Height

Limit Switch cuts out the lifting function once the plat-
form reaches 80.4 ft (24.5 m). This maximum height is
only achieved when the outriggers are selected and
deployed.

4. Tilt Switch - If the machine is exceeding a tilt angle of 3°,

the platform cannot be elevated beyond 12.14 ft (3.7 m),
or if driving while elevated, the drive function will be cut
out.

5. Outrigger Interlocks - These switches allow the machine

to be driven when all outriggers are completely
retracted. The switch also prevents the platform from
being lifted until the machine is level.

6. Oscillating Axle Limit Switch - When the platform is

raised above 12.8 ft (3.9 m) and the axle inclination is
>1°, the drive function is cutout. When the platform is
below 3.9 m, the inclination of the axle is ignored and
driving is possible.
