manual abstract
5.951-949. Use of the cleaner Use this unit exclusively for – cleaning with high-pressure jet and detergent (e.g. cleaning of machines, vehicles, buildings, tools), – cleaning with high-pressure jet without detergent (e.g. cleaning facades, terraces, gardening equipment). For stubborn dirt we recommend the dirt blaster as an optional accessory. Safety features Relief valve with pressure switch On reducing the flow rate with the pressure and flow control, the relief valve opens and part of the water runs back to the suction side of the pump. If the lever of the hand-held spray gun is released, the pressure switch switches the pump off. If the lever is retracted, the pressure switch switches the pump on again. The overflow valve and pressure switch have been set and sealed at the factory. Adjustments are made only by Customer Service. Operating Instructions HD 10/25 S VEX English Preparing the unit for use Unpack the unit – When unpacking the unit, check the contents of the packaging. If there has been any damage in transit inform the dealer. – Do not dispose of the packaging with the household rubbish, hand it in at the appropriate collection point for recycling. Check the oil level • Read the oil level displayed while unit is at a standstill. The oil level must be above the two indicators. Activate the oil reservoir vent • Unscrew the fastening screw of the hood and remove the hood. • Cut off the tip on the cover to the oil reservoir. • Fasten the unit cover. Mount the accessories • Mount nozzle on the spray lance (see markings on the top of the setting ring). • Fit the spray lance to the hand-held spray gun with pressure and flow control. • Lock cable clincher into bore lateral to the handle. • Tighten the high-pressure hose accordingly. Switching on the unit Electrical connection Caution! The voltage specified on the model rating plate must correspond to the voltage supplied. Caution! The maximum tolerable mains impedance at the electrical contact point (see Technical Data) must not be exceeded. Caution! Use an extension cable with a sufficient cable cross-section (see Technical Specifications) and unwind it fully from the cable drum. For connected loads see model rating plate/ Technical Specifications. Caution! It is essential that the unit is connected to the power supply by means of a plug. An inseparable connection to the power supply is prohibited. The plug is used to disconnect from the mains. Water connection/Suction feed operation Connection to water main Caution! Pay attention to the regulations of the water supply company; according to DIN 1988, the unit may not be connected direct to the public drinking water supply. A short-term connection via a non-return valve (Order no. 6.412-578) is allowed. For connected loads see Technical Specifications. • Connect a supply hose (not supplied) to the water outlet on the unit and to the water inlet (e.g. water tap). • Open water inlet. English Operating Instructions HD 10/25 S VEX Suctioning water from an open container • Screw suction hose with filter (Order no. 4.440-238) to the water outlet. • Vent the unit before using. • To evacuate air from the unit, unscrew the nozzle and leave the unit running until water exits with no air bubbles. • Switch off the unit and screw the nozzle back on. Operating the unit ! Danger! Observe the relative safety regulations when using the unit at filling stations or other high-risk areas. Caution! Only clean engines in places which have appropriate oil separators (protection of the environment). Caution! Only wash animals with the low- pressure fan jet (see "Selecting the type of spray"). Operating with high pressure The unit is equipped with a pressure switch. The motor only starts up when the lever is retracted. • Set the unit switch to "I". The indicator light will go green. • Unlock the hand-held spray gun and retract the lever of the gun. • Adjust operating pressure and flow rate (+/–) by rotating the pressure/flow control (infinitely variable). • At the lowest flow rate the waste heat from the motor will heat the water to approx. 15 °C. Selecting the type of spray The handgun must be closed. • Rotate the housing of the nozzle until the desired symbol corresponds with the marking. • Select pencil jet or fan jet by contactless changeover: rotate the spray lance, which is pointing down at an angle of approx. 45°, to the left or right. Explanation of the symbols High-pressure pencil jet (0°), for particularly stubborn accumulation of grime. High-pressure fan jet (25°), for dirt accumulation over a large surface. Low-pressure fan jet (CHEM) for operation with detergent or for cleaning at low pressure. Operating Instructions HD 10/25 S VEX English Operating with detergent Caution! Unsuitable detergents can harm the cleaner and the object which is to be cleaned. Use only detergents which are released by Karcher. Proportions of detergent to be used and accompanying instructions should be noted carefully. Use detergents spa...
