Before starting the cleaner
B1. Before using the cleaner for the first time, check it care-
fully to detect any faults or damage.
In the event of any
damage contact your Nilfisk dealer immediately. Unfold
and lock the handle in working position.
CAUTION!
Never lift the cleaner alone. Always ask a second person
to help.
C
Setting up the unit
C1. Check the oil level. On level ground, the oil should be
above MIN level (A), when the oil is cold.
C2. Fill up detergent tank
1)
:
1. Fill up detergent tank with prediluted Nilfisk detergent.
2. Pull detergent hose and filter out of the storage and put
it through the opening of the detergent tank filler cap.
C3. Connecting the high pressure hose
a
. Machines without high pressure hose reel: Put the
quick connector of the high pressure hose onto the nipple
on the cleaner.
NOTE! The maximum length of high pressure hose is 50
m.
b. Machines with high pressure hose reel:
1. Put the quick connector of the high pressure hose (A)
onto the nipple on the axle.
2. Put the high pressure hose into the hose guide (B) and
fix it with the clip
1)
.
3. Release the brake (C) on the hose reel guide
1)
and wind
up the high pressure hose.
C4. Connecting the water supply:
1. Rinse the water supply hose briefly in order to prevent
sand and other dirt particles entering into the machine.
2. Connect water supply hose to the machine.
3. Open water tap.
NOTE! In the case of poor water quality (sand, etc.), we
recommend that a fine water filter is fitted to the machine.
Max 50 Micron filter.
NOTE! We recommend the use of a textile-reinforced
water hose with a nominal diameter of min. 3/4” (19 mm).
C5. BA valve: This high pressure washer/cleaner is only
allowed to be connected with the drinking water mains,
when an appropriate backflow preventer has been in-
stalled, Type BA according to EN 60335-2-79.
The BA valve can be ordered under number (C: BA valve):
• BA valve including GARDENA couplings: 106411177
• BA valve including NITO couplings: 106411178
• BA valve including GEKA couplings: 106411179
• BA valve without couplings: 106411184
The couplings can be ordered under number (A: Female
coupling, B: Male coupling):
• 3/4” GARDENA (): 1608629
• 3/4” GARDENA (): 32541
• 3/4” NITO (): 1602945
• 3/4” NITO (): 1600659
• 1/2” NITO (): 1604669
• 3/4” GEKA (): 1718
• 3/4” GEKA (): 1311
Installation guide:
1. Mount a male coupling on the water tap.
2. Connect (A) on the BA valve to the water tap.
3. Mount a female coupling on the water inlet hose.
4. Connect (B) on the BA valve to the water inlet hose.
5. Connect the water inlet hose to the high pressure
washer.
6. Turn on the water and start the machine.
CAUTION!
• The backflow preventer can be mounted either verti
cally or horizontally, and the drain opening () must
be mounted pointing downwards.
• Water flowing from the drain opening () must be
able to flow freely.
• If there is a risk of running sands in the inlet water
(i.e. from your own well), an additional filter should
be mounted between the water tap and backflow
preventer.
• The length of the hose between the backflow pre-
venter and the high pressure washer must be at
least 12 metres (min diameter 3/4 inch) to absorb
possible pressure peaks.
• As soon as water has flown through the BA valve,
this water is not considered to be drinking water any
more.
• Protect the backflow preventer against any exposure to
frost.
• Keep the backflow preventer clean, and free of
dirt.
