Usage Features
The MARI-CLEAN MS 501/30 is designed for ease of operation and maintenance.
Before Start-up:
- Ensure high pressure pump water inlet is connected to a water supply hose with sufficient flow (1.5 times the rated water capacity) and pressure (0.5 to 4 bar).
- Check the oil level of the pump using the dipstick or sight glass; it should be between the markings or above the red dot. Use SAE 15/40 gear oil. Never use hydraulic oil.
- Verify electrical connections and ensure extension cables meet specified requirements (e.g., 25 mm² for 0-50 m, 35 mm² for 50-150 m, 50 mm² for 150-200 m).
- Flush the filter by letting water run through for 10 seconds until clean. Check and clean/flush the inlet filter daily or when needed.
- In case of initial start-up or after a long period of inactivity, minor water leaks may occur at plunger seals due to hardened seals. Allow the machine to run for one to two hours for seals to reline.
Starting and Operation:
- Start the unit by turning on the feed water supply.
- Pull the spray gun trigger to allow water to flow through the high-pressure hose and spray gun before attaching the lance and nozzle.
- Turn the high-pressure cleaner stop/start switch to "1".
- Release the emergency switch by turning it clockwise if activated.
- Always point the spray gun nozzle downwards before pulling the trigger.
- Maintain a tight grip on the spray gun, pull the trigger, and begin working.
- When the trigger is released, water flow stops, and the pump stops operating after reaching the maximum cut-off set pressure.
- For idle periods, turn the stop/start switch to "0".
- In case of emergency, press the red button.
Nozzle Selection and Cleaning Tasks:
The unit offers various nozzles for different cleaning tasks:
- 15° nozzle: For stripping and tough cleaning (removing paint, grease, dirt from wood/stone/metal, marine growth, rust from steel, oxidation from aluminum, heavy mildew stains).
- 25° nozzle: For general cleaning (cleaning roofs, gutters, surfaces from dirt/mud/soot/grime, removing algae/bacteria from pools/basins, light mildew stains, rinsing surfaces before painting).
- 40° nozzle: For light cleaning (general light cleaning and rinsing of cars, boats, patios, pools, and similar).
- Roto nozzle: Provides a rotating jet for effective cleaning. Always point downwards before pulling the trigger.
Safety Precautions:
- DANGER: Indicates a situation that, if not avoided, could result in fatal injury or damage to health.
- WARNING: Indicates a situation that, if not avoided, could result in serious injuries to person and/or damage to equipment/environment.
- CAUTION: Indicates a situation that, if not avoided, could result in injuries to person and/or damage to equipment/environment.
- Always follow rules and instructions in the manual and by law.
- Always follow shut-down procedures before any work.
- Always follow start-up procedures when equipment is to be restarted.
- Never point a high-pressure spray gun towards people or living creatures.
- Use only proper hoses and accessories sized for the unit's maximum operating pressure.
- Before maintenance or repair, stop the motor, cool down the unit, and release pressure.
- Wear appropriate personal protective equipment (e.g., STROMME HP500 Standard Protection Kit, including overall, helmet with visor and ear protection, safety goggles, boots, and gloves).
Maintenance Features
The MARI-CLEAN MS 501/30 includes a scheduled maintenance program to ensure optimal performance.
Scheduled Maintenance Table:
- Daily: Check for water leaks, oil level/quality, oil leaks, and flush the filter.
- Weekly: Check the unloader valve.
- ~50 h: Check the filter.
- ~500 h: Check nozzles (replace if worn or incorrect size), change oil.
- 1500 h: Change seals.
- 3000 h: Change valves.
General Advice:
- Observe for wear in intervals of 1500 hours and check again after 2000 hours and each 500 hours.
- Valves typically require changing completely at every other seal change.
- Remember to service the regulator/unloader/relief valve at each seal servicing and check all system accessories and connections before resuming operation.
- Check the filter regularly and change when necessary.
- Inlet filter: Flush the inlet filter before every start-up. Check and clean the filter regularly and change when necessary. When the high-pressure cleaner is in use, check the filter for leakage.
- Freezing precautions: If the pump is used in areas with freezing temperatures, fill the pump and fixed piping with anti-corrosion and anti-freezing solution.
Troubleshooting:
The manual provides a comprehensive troubleshooting guide covering various problems, causes, and actions, such as:
- Cleaner does not start: Electrical power supply failure, motor thermal relay switches off, missing phase.
- Insufficient feeding: Too high/low pressure, too big/worn nozzle, low oil level, obstructions in feeding line, dirty/small inlet filter, incorrect unloader valve operation, valve seizing, excessive leakage from gaskets, insufficient water flow.
- Excessive low flow: RPM too low, too much water bypassed, worn valves, leakage from pressure gaskets, wrongly sized suction pipe, insufficient water flow.
- Pipes are knocking or vibrating: Water temperature too high, air suction, incorrect operation of valves.
- Pump runs but does not produce pressure: By-pass line not working properly or undersized, pump not primed and running dry.
- Pump is very noisy: Worn bearings, high inlet water temperature, problems with pump-motor connection.
- Short plunger seal life: Cavitation or air in the system.
- Water in the oil: Damaged ceramic plunger, excessive pressure/temperature of pumped water, worn plunger shaft oil seal, oil emulsified.
- Water leakage between crankcase and manifold housing: Worn seal pack or plunger seal.
- Pump is overheated: Worn plunger shaft oil seal, problems with pump-motor connection, oil not changed regularly, excessive pressure, pump overloaded, unloader valve issues, too low oil level, wrong oil type.
Spare Parts:
A list of recommended onboard spare parts is provided, including repair kits for the pump and Roto nozzle, HP gun, various nozzles, unloader valve, flow switch, safety valves, V-belts, pressure gauge, and filter elements. When ordering, always state the equipment type and serial number.
