Remedy of faults

Malfunction
Vapour escapes from the unit
The unit develops noise and/or heavy vibration
The unit does not suck or its performance re-
duces
Low suction capacity
The container does not empty
Poor unit switching behaviour between the con-
tainers, or no switch-over

Maintenance and cleaning

Standard cleaning (Fig. F - H)
– Switch the unit off at the power switch (16) and pull out the power plug.
– Remove all hoses.
– Unlock the container lock (18).
– Remove the motor housing (17).
– Flush the inner tank (19), but do not remove.
– Unlock the engagement plates (21) beneath the foam filters (22).
– Remove the foam filters (22) and wash out with clean water.
Note: Foam filters are wear parts. Check the foam filters at the same time. If damaged, only replace with original
OASE spare parts.
Clean inner tank, collector, intake distributor and drain valve (Fig. I - K)
– Intake distributor (Fig. J): Turn the intake distributor (4) out of the bayonet closure (14). Check the completeness
and condition of the rubber seals (25) in the intake distributor.
– Rinse the intake distributor.
– Remove the inner tank (Fig. I 19) and rinse.
• Check the condition of the rubber seal (27).
• Rinse the collector (Fig. K 24) and drain valve (23).
• Check seating and ease of movement of the flap (26) in the drain opening.
Note: Sealing rings and valve rubber elements are wear parts. If damaged or lost, only replace with original OASE
spare parts.
Reassembling the unit
Subsequently, reassemble the unit in the reverse order. Do not forget to lock the motor housing using the engagement
hooks (Fig. J, 18).

Cause
In cold weather, condensate forms in the unit,
which is released in the form of water vapour.
The tank is full
Intake distributor, drain or foam filter is soiled
No mains voltage
Excessive height difference between water
level and unit
Both containers are full of water. The float bod-
ies seal completely
Dirt plugs foam filters, the suction tube or the
suction hose
The flap at the intake distributor is jammed or
soiled
O ring at the inlet distributor not properly seated
The flap at the outlet valve is jammed or soiled
O ring at the inner tank not properly seated
Slide in the suction handle is open
Increased tube friction resistance
Suction depth too large. Due to the design, the
suction capacity reduces as from a suction
depth of 2 m
The drain hose is kinked or was not laid with an
incline
Drain hose or drain valve plugged with dirt
Dirt film on the pistons after an extended down
time
Remedy
This is normal. No remedy necessary
Drain tank
Switch off the unit, wait 20 s, then switch on
again. If the malfunction reoccurs, clean the
unit.
Check mains voltage
We recommend that the outlet height is slightly
above the water level
Drain the unit
Remove dirt
Remove the intake distributor. Check the flap
seating (Fig. I, 4)
Check the O-ring seating (Fig. I, 4)
Remove the drain hose. Check the flap seating
Check the O-ring seating (Fig. I, 27)
Close the slide in the suction handle
Keep the suction hose as short and flat as pos-
sible.
Reduce the suction depth
Route the hose correctly. See Installation.
Remove dirt from the drain hose and the drain
valve
Remove motor housing (G, 17). Start the
switching cycle manually by holding the motor
head overhead.
