Your CONTRACTOR DIESEL washer has
been developed and manufactured in
accordance with the latest working safety
regulations.
Caution! However, to prevent possible perso-
nal accidents or damage to any other product,
we advise you to read carefully through this
section on safety precautions before you
operate your washer for the first time.
General safety precautions
1. Always use both hands for operating spray
equipment to maintain complete control of
the lance.
2. Water jets should never be directed towards
people, pets, electrical wiring or the ALTO
CONTRACTOR DIESEL machine itself.
3. Always switch off engine during work breaks.
4. Connect or disconnect the high pressure
hose ONLY when the engine is stopped.
5. Use only those hoses and nozzles
specified by ALTO.
6. The machine should only run for a
maximum of five minutes once the spray
handle has been released (the pump then
circulates the water internally and the
machine will overheat unless stopped after
5 minutes).
7. The pump is equipped with a high pressure
relief safety valve. This adjustment, like any
others that require the use of tools, should
only be made by a trained service technician.
8. Operating the machine when it, or any
attachments are frozen, is dangerous. Be
sure everything is thawed before operating
the machine.
9. Manufacturer’s instructions for the use of
any detergents should be carefully
observed at all times.
10. During work breaks, or any time lances or
accessories are changed, the spray handle
must be secured by rotating the safety
knob into position O.
