4.1.

GENERAL INSTRUCTIONS.

Your scissors-lift type platform is mobile.
All movements are controlled from a control panel located on the platform extension.
This is the main control panel. The control panel on the frame is for use in case of accident or malfunction.
4.2.

SAVETY DEVICES.

To prevent any risk of accident, safety devices to protect the personnel and machine are fitted in case the
machine is used beyond its performance scope.
These devices immobilise the machine and disable movements. In this case, poor knowledge of the machine
characteristics and operation may cause the operator to diagnose a fault, whereas the safety devices are in
fact working properly.
It is therefore essential to understand all instructions in the following sections.

4.2.1. Driving.

Reminder:
The platform is designed for use on hard ground with a slideslope or grade not over maximum allowable tilt
angle. If this value is exceeded, the buzzer sounds, but machine travel is possible to reach the work area, or
for loading/unloading. (see § 2.4).
To drive the machine, it must not be overloaded. Otherwise, it is immobilised.
Models H12SD - H15SD, with or without the bi-energy option, can be driven forward or in reverse at low or
high speed, over short distances, with the platform stowed.
Ditto for models H12DSX - H15DSX and H18SDX at their three travel speeds.
When the platform is up (below 8 metres), the machine can only be driven on hard, flat, level ground with no
obstructions or holes. Only low speed is possible.
The travel and platform-lift functions cannot be performed simultaneously.

4.2.2. Overload.

If the platform receives its maximum load when stowed, the lift function is disabled.
If the platform receives its maximum load when up (pressure limiter), the lower function is disabled.
To re-enable all movements, the load must be reduced.

4.2.3. Stabilisation option.

Machine is fitted with 3 safety devices:
• Travel functions are disabled when all 4 cylinders are not fully retracted.
• Platform up/down functions are disabled when all 4 cylinders are not in the same state (fully retracted or
extended).
• Stabilisation adjustment can only be performed with the platform stowed. Cylinders extension function is
disabled when platform is up.
4.
THE PLATFORM MUST NOT BE USED IF WINDSPEED EXCEEDS 45 KM/H.
Do not perform manoeuvres before understanding
