Operating instructions
7. Scale prevention - No Scale
Indicator is light: insufficient “No Scale”
Indicator is dark: sufficient “No Scale”
Only use “No Scale” of KEW Technolo-
gy.
To avoid scaling of the burner coil, and thus ensure optimum operation, an scale preventer - “No Scale”
should be added. This product is available from your ALTO distributor. Fill through the socket (13) and it
will automatically be added to the water at the proper rate. If you’re out of “No Scale”, you’ll be able to tell
from the level indicator (14).
3.2 Start-up procedure
Turn control knob to position - I -.
Turn on the water and turn control knob (16) to position - I -. In this position the machine is ready for cold
water operation.
3.3 Operation
Always hold the spray lance with both
hands!
Always lock the spray handle when the
machine is not in operation.
Activate the high pressure washer by squeezing the trigger of the spray handle (7). When first starting, the
pressure may fluctuate because of air in the system. Once the air has escaped, the pressure will become
steady. If necessary, let the machine operate without the spray lance until all air is purged from the inlet
water hose, the pump, and the burner coil.
When the cleaner is not in use, secure the spray handle by turning the locking device (8) into pos. 0.
NOTE: This machine features an automatic start/stop function. When the spray handle trigger is released,
the machine will automatically stop. The machine can be restarted with a simple squeeze of the spray
handle trigger.
