Operation Manual

24
MULTICLEANER 7-53
Original Instructions
9.2.2 Oil change
Lubrication must be made each 200 operation hours.
Shafts for the driving and supporting wheels of the MULTICLEANER
must be lubricated with ordinary lubricant grease. Positioning bolts,
quick connectors, movable segments in the arm, hinges and the en-
try of the tow handle must be lubricated with a lubricant containing
teflon. The easiest way out will be to use a spray with the lubricant.
The pump oil must be replaced after max. 500 hours of operation,
however at least each 6 months. If water in the oil is observed, re-
place the oil and refill with oil of the type Castrol Alphasyn T 150.
9.2.3 Inspection of long
distance nozzle
Normally the long distance nozzle can only be checked visually as it
requires a special equipment to measure it up. If the spray is very
diffuse and not concentrated as usually, the reason may be that it is
either clogged up or worn.
9.2.4 Cleaning of filter in dirt
collector
Before the water valve there is a water filter with a stainless strainer
with a mesh size of 0.25 mm filtering out impurities before they
reach the water valve.
Clean/check the water filter each week or for each 100 operating
hours. This is easily done by using a ratchet wrench with a 24 mm
head and a long adapter and loosening the nut for the dirt collector
from below. If not possible an alternative solution will be to loosen
the union nut of the 3/4" union, remove the hose clamp and the
water hose between the flow switch and the motor/pump unit and
then dismount the tube support. Now the complete unit with compo-
nents for the water supply can be turned around and the nut for the
strainer dismounted.
Rinse/clean the strainer and remount in reverse order. If the strainer
cannot be cleaned, it is possible to buy one separately. It is not
necessary to replace the complete dirt collector.
9.2.5 Inspection of pressure
in tyres
The air pressure in the pneumatic tyred wheels must be approxi-
mately 2.5-2.8 bars. There must be a clearance between the con-
crete floor and the underside of one set of the supporting wheels of
2.5-3 cm, when the MULTICLEANER rests on the two other set of
wheels.
9.2.6 Banjo bolt at the
nozzle head
O-rings and back-up-rings on the banjo bolt at the nozzle head must
be lubricated each 100 operating hours and replaced at regular in-
tervals.
9.2.7 Lubrication
9.2.8 Inspection of initial
tension of the springs
in the cable reel
Inspection of the initial tension of the cable:
If 5 metres of cable have been laid out, the springs in the reel must
provide a tractive effort of 4 kg at a minimum corresponding to a
tractive effort of approximately 8.5 kg at a layout of 30 metres.
Let a Nilfisk-ALTO service technician set the initial tension of the
cable reel.
The life of the springs in the cable reel is approximately 5,000 hours
and the life of the collector ring is approximately 12,000 hours.
