This document provides essential information for the safe and efficient operation of the Bosch UniversalAquatak 125, 130, and 135 pressure washers. Always ensure the unit is on a level surface and never direct the water jet at people, animals, or electrical components.
Device Description
The UniversalAquatak series is designed for cleaning outdoor surfaces, tools, vehicles, and boats using Bosch-approved accessories and detergents. The operating temperature range is 0°C to 40°C.
Setup and Operation
Connect the water supply hose to the machine and the water source. Ensure the main switch is in the '0' position before connecting to the power supply. Open the water tap, release the safety lock on the spray gun, and pull the trigger until water flows uniformly to clear air from the system. Turn the main switch to the 'ON' position and operate the trigger to begin cleaning.
Cleaning with Detergents
Use only detergents specifically approved for high-pressure washers. The supplied high-pressure foam nozzle includes a regulator to adjust detergent flow as needed. For vertical surfaces, apply detergent from bottom to top and rinse from top to bottom.
Maintenance and Storage
Before any maintenance, disconnect the power plug and water supply. Regularly check for loose fixings and worn or damaged parts. After use, drain the high-pressure hose by operating the trigger. Clean the exterior with a soft brush and cloth; do not use solvents or polishes. Store in a frost-free environment and ensure cables are not trapped.
Troubleshooting
If the motor fails to start, check the power connection, fuse, and extension cable. If the pressure is pulsating, ensure there is no air in the water supply and that the water filter is clean. For persistent issues, contact an authorized Bosch service center.
