Foam Lance Karcher TR Advanced for HD/HDS pressure washers, model 4.112-063.0, adjustable spray

Foam Lance Karcher TR Advanced for HD/HDS pressure washers model 4.112-063.0 is a high-pressure foam applicator designed for use with compatible Karcher HD and HDS machines. The unit produces stable detergent foam that adheres to vertical and horizontal surfaces, helping to loosen dirt and reduce the need for manual scrubbing. An adjustable spray nozzle allows control over foam thickness and coverage, and the lance connects to standard high-pressure gun/lance fittings on commercial Karcher systems.

Advantages

The foam lance creates consistent, clingable foam that improves dwell time of cleaning agents and enhances chemical efficiency. Its adjustable spray control provides a range from narrow to wide foam patterns to match different cleaning tasks. The construction is intended for professional use with compatible high-pressure washers and supports even application across vehicle bodies, façades and other treated surfaces. Using the foam lance reduces water and labour by delivering detergent precisely where it is needed.

Suitable for

• Pre-washing passenger cars, commercial vehicles and motorcycles
• Applying cleaning agents to building façades, gutters and exterior walls
• Cleaning workshop floors, equipment and other hard surfaces before rinsing
• Use in professional car wash and maintenance operations

Key specifications

• Compatibility: designed for Karcher HD and HDS pressure washer lance/gun connections
• Adjustable spray: variable foam pattern and detergent output control
• Detergent delivery: built to produce clingable foam for improved chemical contact time
• Materials: components suitable for use with commercial high-pressure systems

How to use

Attach the foam lance to the high-pressure lance or gun of a compatible Karcher HD or HDS pressure washer following the machine manufacturer’s connection instructions. Fill the built-in detergent tank or bottle with an appropriate foam-capable cleaning agent diluted according to the detergent manufacturer’s guidance. Start the pressure washer, set a low-pressure or dedicated foam mode if available, and adjust the spray nozzle to obtain the desired foam thickness and coverage. Apply foam from a suitable distance to ensure even coverage, allow the foam to dwell for the recommended time, then rinse with high-pressure water until all residue is removed.

Usage recommendations

Use only detergents formulated for foam application and compatible with high-pressure systems. Observe safety data sheets and wear appropriate protective equipment when handling concentrated chemicals. Avoid prolonged application on sensitive painted surfaces; test on a small area first. Regularly inspect seals and fittings for wear and replace parts as needed to maintain safe operation and consistent foam quality.
