• CAUTION: Make use only of liquid deter-
gent, do not absolutely use acid or too
much alkaline products. We suggest you to
make use of our products, which have been
studied for the use with washer machines.
• CAUTION: For proper use of the tank, do
not introduce flammable or chemically
harsh substances.
The adjusting head allow you to select water
jet at low and high pressure. Pressure can be
adjusted by acting on nozzle knob (pict.17):
pict."B" means low pressure, "A" means high
pressure. The selection of low or high pressure
shall be carried out with gun in closed posi-
tion. The detergent suction is automatic when
the adjusting head of the lance is positioned
for low pressure operation. When you start the
machine, the mixing of the detergent with the
water is automatic at the water passage.

APPLIANCES PROVIDED WITH THER-
MAL VALVE (OPTIONAL)
This device enables the machine's by-pass op-
eration through automatic water discharge
whenever it reaches a temperature of nearly
60°C and cooling working components.
• CAUTION: appliances that are not provided
with this disposal must not operate for more
than 2 minutes with released gun. Recycled
water raises its temperature remarkably caus-
ing great damages to the pump.

GUN SAFETY DEVICE
Whenever the machine has to be stopped, it is im-
portant to engage the safety catch (pict.14, pos.
S) on the gun so that it cannot be operated ac-
cidentally.
> STORAGE
(pict.17,18,19,20)
- Move the machine only by grasping the carrying
handle
- Store the appliance and the accessories in a frost-
safe room.
Appliances and accessories that are not completely
drained can be destroyed by frost. Completely
drain appliance and accessories and protect them
against frost.
To avoid damage:
- Detach the appliance from the water supply.
- Detach spray lance from the trigger gun.
- Switch the appliance on ("I/ON"), press the trig-
ger gun lever until no further water is discharged
(approx. 1 min). - Turn off the appliance (pict.21).-
Store the appliance and the entire accessories in a
frost free room (pict.22).
CARE AND MAINTENANCE
SCHEDULED MAINTENANCE PLAN
Visit www.lavorservice.com website and
download the scheduled maintenance
IMPORTANT: Before doing any work on
the cleaner, discharge the pressure and dis-
connect the electricity and water supplies.
CHECKING THE PUMP OIL LEVEL
Check the oil level periodically. The oil must be
changed for the first time after 50 working hours,
with subsequent changes every 500 hours. SAE
20/30 oil is recommended - Oil capacity 0,5 Kg
CHECKING THE WATER INTAKE FILTER
Inspect and clean the water intake filter (pict.23)
on the intake union periodically. This is impor-
tant to prevent fouling which may impair ope-
ration of the pump.
REPLACING THE SPRAY ROD NOZZLE
Replace the nozzle when the pressure drops below
the normal values.
ELECTRICAL CORD
• WARNING: Take care not damage the electric
cable. Have a damaged power cord replaced
immediately by an authorized service point or
an electrical specialist.
