water under high pressure through the high
pressure hose and hand gun to the 3-way nozzle.

2. Operation with suction feed

When the motor ist switched on, the pump
draws water from the water tank or container
through the filter and non-return valve and
delivers it at high pressure through the high-
pressure hose and hand gun to the 3-way
nozzle.

3. Operation with detergent

When the 3-way nozzle is switched to fan jet,
detergent is drawn by the injector through the
detergent suction hose and is mixed with the
water delivered by the pump. On the HD 1050
cleaner, the amount of detergent fed can be
steplessly adjusted by means of metering valve.
