6.0 Maintenance

Your ALTO high pressure washer is maintenance-free and therefore no special qualifications are required
for the daily use.
However, it applies to the most exposed components that a minimum of maintenance ensures a prolonged
and problem-free operation. Therefore it will be a good idea to make a habit of the following:
Before mounting the water hose and the high pressure hose the quick couplings should be cleaned of
dust and sand.
Before mounting spray lance or any other accessory on the spray handle, the machine should be
started and the quick coupling cleaned of dust and sand.
The machine should be stored in a frost-free room. If by mistake the machine freezes up, it must not
be started. Let machine, hoses and accessories thaw up before starting up.
NEVER START A FROZEN UP MACHINE.

6.1 Oil

The oil should be changed after each 1000 hours' use.
Remove the cover of the oil glass (Pos. 4). Unscrew the drain plug (Pos. 13). Allow the oil to run out and
clean the drain plug of impurities. Screw in the plug and refill the pump with fresh oil through the oil glass.
Holds approx. 1 l.
From ALTO the pump is filled with zincless hydraulic oil - ALTO Pump Oil 100. When refilling and changing
the oil this or an oil with the following specifications should be used:
ISO no. 100
Viscosity index (VI) min. 130
Pour point below -30°C

6.2 Sludge container

The used oil is caught in a sludge container (Pos. 11). The container should be emptied before it is full; this
oil must not be reused in the pump.

PROTECT THE ENVIRONMENT

Waste oil and oil sludge must be removed as laid down in the instructions.

6.3 Water filter

To avoid debris entering the high pressure pump, a water filter is fitted at the water inlet. Dependent on the
purity of the water this filter will have to be cleaned at regular intervals. The filter can be removed when the
quick coupling (Pos. 2) has been unscrewed.

6.4 Cleaning of high pressure nozzle

A clogging up in the nozzle causes a pump pressure which is too high, and cleaning is immediately re-
quired.
1. Stop the cleaner and dismount the spray lance.
2. Clean the nozzle with ALTO nozzle cleaning tool no. 6401654.
IMPORTANT: ONLY use the cleaning tool when the spray lance is dismounted
3. Flush the spray lance backwards with water.
4. If the pressure is still too high, repeat items 1-3.
