Operating Principle; Checking And Adjustment - Kesla XS 190 Operation & Maintenance Manual

Operating principle

The purpose of platform load control is to prevent the platform from being loaded in excess
of the maximum permitted load (230 kg). When the platform load reaches the highest
admitted load (230 kg), the max. platform load warning light lights.
When the platform load exceeds the highest admissible value, the reach limit warning light
lights up simultaneously with the max. platform load warning light, and a sound alarms.
When the max. platform load is being exceeded, all movements are prevented. The
functions return to normal when the platform load is below the maximum value.
If the platform load control is defected, please contact the manufacturer.

Checking and adjustment

Check the platform load control as follows:
1. Support the Access Platform on outriggers. Lift the boom from the transport
support. Switch off the engine.
2. Leave the ignition on.
3. Perform the check-up using to persons, whose body weights are known, for
instance 90 kg + 80 kg = 170 kg
4. Add weight to the platform so that the total weight is 230 kg.
5. At 230 kg load the platform load warning light should light. For best result the
persons should move around in the platform as if they were working. The precision of the
platform load control is approx. ± 15 kg.
6. Gradually increase the platform load. The overload alarm should be activated
before the platform road reaches 276 kg. When the overload alarm is activated, start the
engine to check whether all the normal boom movements are prevented. Switch off the
engine and try the movements using the emergency lowering pump. It should be possible
to operate the movements.
7. Remove the load from the platform. The overload alarm and the max. platform load
signal lamp should be switched off as the load is reduced. Pay attention to the accuracy of
the measuring procedure.
8. Should the platform load control not work properly, lubricate the bearings (3) of the
cranks (2) and repeat the check-up procedure. Adjust as required.
