To ensure good suction performance, the following points
must be met:
•
sufficient speed
• a powerful turbine
• an appropriate driving speed
• the correct height setting of the suction nozzle.
1. Your leaf and waste vacuum cleaner is equipped with a
very powerful 1.5 kW asynchronous electric motor. This
ensures that there is always enough power available.
2. The proven design of the turbine ensures excellent
suction power. However, only a well-balanced and
undamaged turbine can provide a decent performance.
3. The adjustment of the driving speed is controlled by
the finely graduated gearbox with 6 forward gears and
one reverse gear. This allows you to adjust the driving
speed in any situation to achieve the desired suction
power. The differential gearbox allows for unrestricted
manoeuvrability.
4. The infinitely variable height adjustment of the suction
nozzle by means of the rotating spindle determines the
suction power. The suction nozzle should only be set
so low until a proper suction power is achieved. Too
low a setting impedes manoeuvrability and causes
damage to the suction nozzle; the suction power does
not improve as a result. If the setting is too high, there
is a lack of suction power and the suction performance
is insufficient.
Suction dry leaves
Dry leaves are shredded by the turbine during suction.
Set the suction nozzle only as close to the ground as
absolutely necessary to keep the unit optimally manoeu-
vrable. Remember that when used in dry terrain, both
the unit and the collecting bag hardly get dirty. This is
different with wet leaves. After vacuuming large areas, it
is essential to wash the collection bag.
Suction wet leaves
We generally recommend the wet collecting bag for this
purpose. Due to the larger pores, it remains permeable
to air even after working for a long time.
With wet leaves, the suction nozzle must be guided as
close to the ground as possible. To achieve a good suc-
tion performance, the driving speed should be adjusted
accordingly (slowed down). You should work in 2nd or
3rd gear.
Suction waste
For dry paper waste etc. select a height set-
ting as required for beverage cans.
However, if paper waste is already soaked, a second
operation with a low setting (cf. wet leaves) may be
necessary. As with leaf suction, always ensure a clean,
air-permeable collecting bag.
Note:
The collecting bag should be washed out and dried each
time after work. Hand or machine wash up to 40°C. Keep
the zip smooth after each wash with a little talcum powder.
Warning:
Do not vacuum glass or ceramic waste,
such as bottles and broken glass.
Bottles, like other waste, are crushed in the turbine.
Sharp-edged shards could puncture the collecting bag.
Risk of injury from ejected pieces of glass or from
handling the waste.
