REMEDIES
Always use two hands when operating a pressure washer. This will assure
complete control of the equipment.
Always test the GFCI plug prior to using the cleaner.
Never test the pressure of the cleaner against any part of the body.
Use the trigger lock whenever the spray gun is not being used for cleaning.
Always seek emergency medical care immediately if any fl uid penetrates the
skin. A cut may be deeper and more serious than it appears.

ENERAL RULES
3.1.1 The USE and MAINTENANCE manual constitutes an essential
part of the cleaner equipment and should be kept in a
safe place for future reference. If you sell the cleaner, the
manual should be handed on to the new owner.
3.1.2 Before starting the cleaner, make sure that it is receiving
water correctly. Operating the cleaner without water could
damage the seals.
3.1.3 Do not disconnect the plug by pulling on the electrical cable.
3.1.4 If you are too far from the object you wish to clean, do not
move the cleaner nearer by pulling on the high pressure
hose; use the handle provided.
3.1.5 Protect the cleaner from freezing during the winter. Store in
a warm area.
3.1.6 Do not obstruct the ventilation grilles during operation.
3.1.7 The cross-section of any extension cord used must be
proportional to their length, i.e., the longer the extension
cord, the greater the cross-section; cables with a protection
level of “IPX5” must be used. See table A.
