Starting And Operating Of The Machine; After Use - Nilfisk-Advance GD 320 Instrucciones De Uso

NOTE! Before dry material pick-up - All models
Dry cleaner shall always have the sack fi lter mounted in
the machine.
Wet cleaner shall always have the sack fi lter and the
float system mounted when picking up dry material.
This is also valid when using a dust bag.
NOTE! Before wet pick-up - not for GD 320
Never use dust bag or sack fi lter when performing wet pick-up.
The machine is equipped with a fl oat system that shuts off the
airflow through the machine when the maximum liquid level is
reached. Never pick up liquid without the float body in place.

the motor top . Then remove the motor top. Check that the
float basket and float valve are mounted at the motor top.
Remounting the motor top: Put back the motor top to the con-
tainer. Make sure that the switch/switches is located in direction
towards the suction inlet. Then tighten both latches so that the
motor top is properly secured. Always use a chemical defoamer
when picking up water containing foaming detergents. Use
a defoamer recommended by the detergent manufacturer.

1 Starting and operating of the machine

Check that the electrical switch is switched off (in position 0). Then
connect the suction hose into the suction inlet at the machine by
pushing the hose forward until it snaps in place at the inlet (to
release the hose from machine just push the release button down-
wards and then pull out the hose). Then connect the two tubes with
the hose handle, twist the tubes in order to ensure that they are
properly fi tted. Attach suitable nozzle to the tube. Choose nozzle
depending on what type of material that is to be picked-up. Connect
the plug into a proper electrical outlet. Put the electrical switch into
position 1 in order to start the motor. Some variants have two mo-
tors/fan units and two electrical switches - one switch for each motor.
GWD 350 & GWD 375 Adjusting the handle
The handle can be adjusted to the suitable working heigth. Start by
loosing the two locking screws at each side of the handle. Then adjust
the handle by moving it upwards or downwards until the proper angle
is found. Tighten the both locking screws again to secure the handle
Wet pick up - Note! Not for GD 320
The machine is equipped with a fl oat body that shuts of the airfl ow
through the machine when the maximum liquid level is reached.
You will then hear a noticeable change of the sound from the motor
and notice that the suction power decreases. When this occurs,
switch the machine of. Disconnect the machine from the socket.
See item number 2 for emptying after wet pick-up.
Craftsman versions
These variants have an extra electrical outlet for connecting an drilling
machine or other electrical tools. Max 2000W power consumption
is allowed at the electrical tool to be connected. Your cleaner can
then be used to pick up wooden drillings and similair materials. The
electrical outlet is placed under a plastic cover at the front side of
the motor top. The electrical switch have two different positions.
Position I: normal operation. The machine will be shut off when the
switch is placed in position 0.
Position II: craftsman operation. The extra electrical outlet is ac-
tivated in this position. The vacuum cleaner is now started by fi rst
connecting an electrical tool to the electrical outlet and then starting
the electrical tool. When the electrical tool is shut off the vacuum
cleaner has 10 seconds delayed shut off. The meaning of the
delay is to ensure that the cleaner has time to pick-up the material.
2 Emptying after wet pick-up
Before emptying the container, unplug the vacuum cleaner. Al-
ways empty and clean the container and the fl oat system after
picking-up liquids. Never pick up liquid without the fl oat system
installed in the machine.
INSTRUCTIONS FOR USE

2a) Release the latch by pulling the lower parts outwards so that
the motor top is released. Lift up the motor top.
2b) Disconnect the hose from the inlet by pressing the button on the
hose connection downwards. Then pull out the hose.
2c) Empty by tilting the container backwards and pour the liquids into
a fl oor drain or similar. Wipe the fl oat valve and fl oat basket with a
damp cloth before the motor top is reinstalled to the container.
2d) Wipe the fl oat valve and the fl oat basket with a damp cloth.
2e) Put back the motor top to the container. Secure with the latches.
Emptying: GWD 350 GWD 375
2f) Drain hose: GWD 350 (optional) and GWD 375 have a draining
hose. Detach the drain hose from the bracket by pulling hose back-
wards from the cleaner. Place the drain hose end near a fl oor drain
and then remove the plug at hose end. The natural pressure will then
drain the liquids from the container.
2g) Emptying from the container: Pull the upper parts of the latches
outwards and release the motor top. Remove the motor top. The suction
hose can be attached during emptying from the container. Grasp with
one hand at the handle at the lower part of the container. To avoid move-
ment of the trolley - place one foot at the basepart of the trolley. Then tilt
the container backwards and pour the liquids into a fl oor drain or similar.
2h) Wipe the fl oat valve and the fl oat basket with a damp cloth.
2i) Put back the motor top to the container. Make sure that the switch/
switches is located in direction towards the suction inlet. Secure with
the latches.
3 Emptying after dry pick-up - all models
Remove the plug from the socket before emptying af-
ter dry pick-up. Check the filters and dustbag regularly.
Release the latches by pulling them outwards so that the
motor top is released. Lift up the motor top from container.
C a r t r i d g e f i l t e r : To c l e a n t h e f i l t e r y o u c a n e i t h e r
shake, brush or wash it. Wait until it is dry before you reu-
se it. Check the motor filter, replace it if it is clogged.
Sackfilter:Grasp the sackfilter and lift it up from clea-
ner. Shake filter so that all dust is removed from the filter.
Dustbag: check bag to ensure the fi ll factor. Replace dust bag
if necessary. Remove the old bag. The new bag is fi tted by pas-
sing the carboard piece with the rubber membrane through the
v a c u u m i n l e t . M a k e s u r e t h a t t h e r u b b e r m e m b r a n e
is passing past the heightening at the vacuum inlet.
After emptying: Put back the motor top to the container. Make sure
that the switch/switches is located in direction towards the suction
inlet. Secure with the latches. Never pick up dry material without
sackfi lter or dustbag fi tted in the machine. The suction effi ciency of
the vacuum cleaner depends on the size and quality of the fi lter and
dust bag. Therefore - use only Original fi lter and dust bags.
4 Maintenance of the fl oat system -
Remove the plug from the socket before performing maintenance.
Always empty and clean the container and the fl oat system after
picking-up liquids.
4a) Release the latch by pulling them outwards so that the motor top
is released. Lift up motor top from container. Turn the motor top to
upside down position.
4b)Then loosen the float basket by turning the basket to
the left. Remove the complete float system from motor top.
4c) A fi lter is located in front of the motor inlet. Check this motor
fi lter and HEPA-fi lter (if fi tted). Replace to new fi lter if fi lter is clogged.
4d) Wipe the fl oat valve and fl oat basket with a damp cloth before
the motor top is reinstalled to the container. Then reinstall the fl oat
valve to the fl oat basket. Make sure that the sealed surface of the
fl oat valve is installed upwards in direction towards the motor top.
4e) To mount the fl oat basket - fi t the arrow at the basket to the arrow
at the motor top. Then secure the fl oat basket by turning it to the right.
