Maintenance and repair

Execution of maintenance and repair tasks requires

specialised skills and an equipped workshop.

As the manufacturer we prescribe that these tasks must

be performed in a qualified workshop!

5.1 Safety guidelines for maintenance and

repair

Prior to maintenance always comply with the instructions in the

“Safety” chapter as well (see chapter 1).

WARNING!

If other persons unexpectedly start up the sweeping machine,

there are a number of injury hazards.
Therefore:

•

Unplug the spark plug connector for maintenance tasks.

WARNING!

Danger of injury due to dismounted protective devices and

safety devices.

If protective devices and safety devices are dismounted they no

longer fulfil their function.

Therefore:

•

Always remount protective devices and safety devices after

they have been dismounted (for example, for service and

maintenance purposes).

WARNING!

The sweeping machine poses significant hazards for non-
specialised persons.

Therefore:

•

Only have maintenance and repair tasks executed by the
specialist dealer. This particularly applies for maintenance and
repair tasks on the motor and V-belt drives.
