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 fluid penetrates the
skin. A cut may be deeper and more serious than it appears.
3. GENERAL 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.
3.1.8 Position the cleaner AS NEAR AS POSSIBLE to the water
supply.
3.1.9 The packaging is easily recyclable, and must be disposed of
in compliance with the regulations in force in the country of
installation.

3.1.10 Use the cleaner only with accessories and replacement
parts authorized by the manufacturer. The use of original
accessories and replacement parts will ensure safe, trouble-
free operation.
3.1.11 The cleaner must be used standing on a secure, stable
surface, positioned as shown.
3.2 Intended Use
3.2.1 The cleaner is intended only for the cleaning of vehicles,
machines, boats, buildings, etc., by the removal of stubborn
dirt using clean water and chemical detergents.
For domestic use only (single-phase motors only). Not for
professional use (for three-phase or industrial motors only),
and only for opration at temperatures above 32° F.
Compliant with EN 60335-2-79/A1 standard.
3.2.2 When using chemical detergents, only use biodegradable
types. We recommend HOBBY – FOAM detergent (#3206).
3.2.3 Only clean vehicle engines in areas in which suitable oil
traps are installed.
3.3 Safety Valve
3.3.1 The safety valve also functions as a pressure-limiting valve.
When the gun trigger is released, the safety valve opens and
the water recirculates through the pump inlet. Never try to
adjust this valve.
4. INSTALLATION/ASSEMBLY
4.1 Fit the lance into the gun by rotating and pushing until the
two parts are completely locked.
4.2 Connect the gun to the high-pressure hose.

4.3 Connect the high-pressure hose to the water (OUTLET) on
the cleaner.
4.4 Connect the water supply hose.
(not supplied) to the water (INLET)
of the cleaner. The supply hose
must have an internal diameter of
at least 13 mm (1/2 in.) and must
be reinforced. The water supply
must be at least equal to the cleaner
delivery capacity.
The intake water temperature must NOT exceed 60° C
(122°F). The water supply pressure must NOT exceed 10
BAR (145 PSI).
4.4.1 CAUTION! The cleaner must only be used with clean water;
use of unfiltered water or corrosive chemicals will damage
the cleaner.
4.5 Turn the motor switch to the “0” position.
4.6 Check that the electrical supply voltage and frequency
(Volts/Hz) correspond those specified on the cleaner data
plate. If the power supply is corect, you may now plug in
the cleaner.
The cleaner must only be connected to power sockets with
regulation earth connection. A differential safety breaker
(30mA) will increase the safety of operators.
CAUTION! The machine may cause electrical disturbances
when starting.
4.6.1 If the motor stops and fails to restart, wait 2 to 3 minutes
before restarting. THERMAL CUTOUT TRIPPED AND MUST
COOL BEFORE RESTARTING.
5. USE
5.1 Turn on the water supply tap FULLY.
5.2 Release the safety catch, then press

pressure. See 5.5 “Proper use of stnadard accessories”.
5.4.2 Fill the detergent tank to the level
indicated through the inlet.
5.4.3 Select LOW PRESSURE (see instructions);
the detergent will be sucked up and mixed
with the water, with the suction rate
regulated by the knob provided.
5.4.4 Now distribute the detergent drawn in and
mixed with water.
5.5 Correct Use of standard accessories.
5.5.1 The cleaner is equipped with the adjustable nozzle, which
provides some important functions:
5.5.2 LOW PRESSURE operation (for suction and spraying of
detergent).
5.5.3. HIGH PRESSURE operation (for high pressure washing and
rinsing).
5.5.4 Jet adjustment from pencis to fan. (For models with this
feature).

5.6.3 Unscrew the adjustable head and fit the rotary nozzle onto
the lance.
5.6.4 Turn the high pressure cleaner back on.
5.7 Recommended Cleaning Procedure
5.7.1 Dissolve dirt by applying detergent with the fan jet to the
dry surface.
On vertical surfaces, work from the bottom upwards. Leave
the detergent to act for 1 to 2 minutes, but do not allow to
dry out. Apply the high preesure jet, keeping the nozzle
at least 10 in. from the surface, working from the bottom
upwards. Avoid allowing the rinsing water to run on the
unwashed surfaces.
5.8 Storage
5.8.1 Switch off the cleaner.
5.8.2 Turn off the water supply tap.
5.8.3 After use, the detergent residues should be removed from
the tank.
5.8.4 Discharge residual pressure by pressing the trigger until no
more water comes out of the adjustable nozzle.
5.8.5 Engage the gun safety catch.
5.8.6 Remove the plug from the socket.
5.8.7 Operate the cleaner with non-corrosive/non-toxic antifreeze
before storing for the winter.
6 MAINTENANCE
6.1 CAUTION! Before working on the cleaner, disconnect
the plug from the power supply
socket.
6.2 To ensure good performance,
check and clean the suction and
detergent filters after every 50
hours of operation.
6.3 Lont periods of disuse may lead to
the formation of lime scale deposits. Working through the
hole on the rear, or a 6 Allen key (6) for models with this
feature.
6.4 Clean the nozzle with the tool provided. Remove the lance
from the gun, remove any dirt from the nozzle hole and
rinse.
