8. General Information
8.1 Safety equipment
Overflow valve with 2 pressure switches
When the water flow rate is reduced with the
servo compression valve on the hand-held spray
gun or with the flow regulator on the pump head,
the overflow valve opens and some of the water
flows back to the pump suction side.
If the gun is completely closed, enabling all of the
water to flow back to the pump suction side, the
pressure switch located on the overflow valve
switches off the pump.
If the hand-held spray gun is opened again, the
pressure switch located on the cylinder head
switches on the pump again. The overflow valve
is set and lead-sealed at the factory.
Adjustments must only be carried out by customer
service.
Safety valve
The safety valve opens when the pressure switch
is defective. The safety valve is set and lead-
sealed at the factory. Adjustments may only be
carried out by customer service.
Low-water safety device
The low-water safety device prevents the burner
from switching on when the water is low. A
strainer prevents the safety device from
becoming fouled and must be cleaned regularly.
8.2 Accessories
Incorrect, badly fitting or defective accessories
impair the function of the appliance and are
dangerous. It is advisable to use Kärcher
accessories which are made-to-order. Your
dealer will be glad to advise you.
8.3 Spare parts
Please note that the use of other than Kärcher
spare parts can result in damage and even
serious accidents if these parts have not been
correctly manufactured, if they do not replace
the Kärcher spare part exactly or if they result in
unsafe operation of the appliance.
Kärcher spare parts guarantee that the appliance
can be operated safely and trouble-free.
A selection of the most common spare-part
numbers are listed at the end of these operating
instructions.
