SAFETY REQUIREMENTS

The indicator is located at the left side of the outrigger valve unit under the cover. The

indicator is a spirit level showing the position of the Access Platform. The accuracy of the

spirit level is + 0.5° - 1.0°.

The Access Platform must be equipped with a device (limit switches 1 & 2) to prevent the

use of the platform before the outriggers are extended to the support position. The support

position is the position where the outriggers are fully extended and the sole plates of the

outriggers are pressed firmly against the ground. The operation of outriggers is prevented,

when the boom is away from the transport support (limit switch 6) and the working platform

has been raised more than 3,0m (9,81ft) from the ground (limit switch 5).

The electric limit switches must be similar to the original ones and so connected

that become safely deactivated (forced opening type).

The Access Platform must be equipped with a device (limit switches 6 & 2) to prevent

outrigger movement when the boom is off the transport position.

The boom lift and the transport support have electrical safety limit switches to

prevent the outrigger movements when the boom is off the transport position. When

moving the boom, the operator must press the pedal in the working platform. In practice,

the transport position does not mean only that the boom has been lowered on the

transport support. The boom is in the transport position also when both the control levers

of drive/outrigger valve and bypass buttons are within the reach of the operator. XS 190

has limit switches for the positions of the outriggers and ground sensor limit switches. The

position sensor is activated, when the outriggers have been turned at least 30° from the

transport position. The ground sensor is activated, when an outrigger us pressed against

the ground with more than six (6) kgs.

The working platform must be securely attached to the Access Platform unit. Any

unintentional swinging, inclining, slewing or moving of the platform must be avoided. The

screws, nuts, joint pints and fixing equipment must be reliably secured or locked.

Use also a cotter pin in double nut securing (fixing the end of the boom chain).

In moving parts, mechanical locks are to be used.

This does not apply to the normal movements caused by the clearances of fixing,

stabilizing, and slewing equipment.

- Nyloc nuts must always be replaced with new ones after loosening.

The working platform must remain in a sufficiently horizontal position (recommendation:

maximum slope ±5º) regardless of the position of the Access Platform.
