This document is a comprehensive operating manual for the Kärcher ICC 2 Euro 3 street sweeper, providing detailed instructions for its function, operation, maintenance, and troubleshooting.
Function Description:
The Kärcher ICC 2 Euro 3 is a street sweeper designed for cleaning soiled outdoor surfaces. Its primary function involves sweeping dirt and debris into a waste container. The machine utilizes a spray-water system (1) to bind dust, side brushes (2) to move debris towards the suction opening (3), and a powerful suction turbine (4) to draw the swept material into the waste container (5). The sweeper is equipped with a diesel engine (VM-Detroit Diesel HR 494 HT3, 4-cylinder Euro 3, 55/75 kW/PS at 2300 rpm) for propulsion and powering the sweeping mechanisms. It features a hydrostatic drive for the rear wheels and hydraulic drive for the front wheels, allowing for variable speed control and maneuverability.

Usage Features:
The ICC 2 Euro 3 is operated from a driver's seat (9) with a steering wheel (1) and an operator console (2). Key controls include an ignition lock (5), drive pedal (22), brake pedal (21), and a driving direction lever (13) for forward (1) and reverse (2) movement. The multi-functional display (1) provides information on motor rpm, coolant temperature, hydraulic oil temperature, fuel tank level, water tank level, operating hours, driving route, speed, time, battery voltage, and service intervals. Indicator lamps (9-17) alert the operator to various system statuses.
The machine supports both 2-brush and 4-brush sweeping systems, with specific pedals (23) and joysticks (2) for raising/lowering and moving the side brushes (4, 5, 6, 7) and the bulk waste flap (8). The side brush speed (2) and inclination (4, 8) can be adjusted to optimize cleaning results. A spray-water system (6) can be activated to bind dust, with adjustable water flow (regulation valve) and a water circulation system for extended operation. The machine can also be configured for leaf suction (accessory) by connecting a suction hose and covering the suction pipe. For safety, the ignition key should be removed when not in use, and the parking brake (11) engaged. The machine is not suitable for sweeping explosive liquids, flammable gases, or undiluted acids/solvents.
Maintenance Features:
Regular maintenance is crucial for the longevity and safe operation of the ICC 2 Euro 3.
- Daily Maintenance: Clean lighting, check engine oil, hydraulic oil, cooler, suction channel grid, cooler water level, air filter, side brushes, suction opening for wear, and all operator control elements.
- Weekly Maintenance: Check suction pipe sealing washer, waste container washers, grease bearings, and tyre pressure.
- Additional Maintenance (every 50 operating hours): Check parking brake function, hydraulic system for leaks, V-belt wear, coolant anti-freeze, hoses and clamps, wheels, connections, and conduits.
- Additional Maintenance (every 150 operating hours): Change engine oil, replace motor oil filter inlay, change air filter, empty fuel filter water separator, check battery acid level, and clean alternator ventilation slits.
- Specific Procedures:
- Refuelling: Diesel fuel only, up to 1 cm below the filler neck to allow for expansion.
- Oil Level Check & Refill: Engine oil (SAE 15W30, SAE 15W40) and hydraulic oil (SHELL Tellus HV 46) levels should be checked and refilled if below the MIN mark.
- Oil & Filter Change: Engine oil and filter should be changed at specified intervals.
- Water Cooler Maintenance: Clean the cooler with low-pressure water or compressed air, not high-pressure. Check coolant level and anti-freeze concentration.
- Fuel Filter Maintenance: Clean or replace the fuel filter, check fuel lines for leaks, and de-aerate the fuel system.
- Air Filter Maintenance: Clean or replace the air filter.
- Lubrication: Grease various points on the front and rear axles, swivel joint, steering cylinder, and brush system (8x points). A central lubrication unit (accessory) automatically greases points at set intervals.
- Tyre Maintenance: Check tyre pressure (front: 3.75 bar, rear: 4.75 bar) and replace wheels if necessary.
- Wiper Maintenance: Clean spray nozzles, adjust spray direction, and replace wiper blades.
- Sealing Strip Maintenance: Adjust or replace sealing strips on the suction opening and bulk waste flap to ensure optimal cleaning and prevent debris leakage.
- Electrical System: Replace bulbs and fuses with identical ratings.
- Shutdown: For long periods of non-use, park on an even surface, raise side brushes, remove ignition key, secure against rolling, fill fuel tank, change engine oil and filter, drain spray water (if frost is expected), empty water tank, disconnect and charge battery, and clean the machine.
All maintenance and repair work should be performed by qualified specialists or authorized Kärcher service centers to maintain warranty validity and ensure safe operation.
