Frequently Asked Questions - Classic 100.5 Gerni

Why won't my pressure washer start?

Check if it's plugged in, try a different socket, replace any blown fuse, and ensure the extension cord is not defective. If the problem persists, consult the troubleshooting section.

What should I do if the pressure fluctuates?

Fluctuating pressure may be due to air in the pump or hose, an inadequate water supply, a partially blocked nozzle, a blocked water inlet filter, or a kinked hose. Allow the machine to run with the trigger open to expel air, ensure proper water flow, clean the nozzle and filter, and straighten hoses.

How do I clean the nozzle?

Use the cleaning needle or a thin wire to clear debris from the nozzle opening. Refer to the user guide (Part 2:3, G) for detailed instructions. Regular nozzle cleaning prevents pressure loss and pulsation.

Can I use any detergent with my Gerni pressure washer?

Use only cleaning agents supplied or recommended by Gerni. Other chemicals may affect safety and machine performance. Always follow detergent instructions for use, emergency, and disposal.

What precautions should I take during operation?

Wear safety boots, respiratory mask (FFP2 or equivalent), ear protection, goggles, and protective clothing. Hold the spray lance firmly with both hands due to kickback. Do not direct the jet at persons, live electrical equipment, or the machine itself.

How should I store the pressure washer after use?

Turn off the machine, disconnect from power and water, drain all water from machine and accessories to prevent frost damage. Wind up the cable and hose carefully. Store in a frost-free location.

What does the thermal protector do?

The automatic self-resetting thermal protector cuts power if the machine overheats. If triggered, wait for the machine to cool down before resuming use. This prevents damage from prolonged operation.

Why does my machine pulsate?

Pulsation is often caused by air in the inlet hose/pump, insufficient water supply, a partially blocked nozzle, a blocked water filter, or a kinked hose. Run the machine with the trigger open to purge air, ensure adequate water supply (min. 1/2" hose), and clean nozzle and filter.

Is it safe to use an extension cord?

Yes, but only if it is suitable for outdoor use and the connection is kept dry and off the ground. Use a cord reel that keeps the socket at least 60 mm above ground. Inadequate extension cords can be dangerous.

What is the warranty period and what does it cover?

Gerni offers a 2-year warranty for domestic use from the date of purchase. It covers defects in materials or workmanship, provided the product is used according to the manual, no unauthorized repairs, and only original accessories are used. Wear and tear, misuse, or commercial use are not covered.

Part 1:3 Safety Instructions, High Pressure Washers, Classic, Classic PG, Super and Super PG

Safety Instructions Original Safety Instructions

Before first use of the machine, read the instructions carefully. Save instructions for later use.

Safety instructions marked with this symbol must be observed to prevent personal injury or serious damage to property.

- The instruction consists of 4 parts. Part 1:3 Safety Instructions. Part 2:3 Serial specifi c User Guide. Part 3:3 Troubleshooting, Serial specifi c Technical Data and Disposal. Part 1:4 Warranty Conditions.

Warnings ⚠️ This machine has been designed for use with cleaning agents supplied or recommended by Gerni. The use of other cleaning agents or chemicals may adversely affect the safety of the machine. High pressure jets can be dangerous if subject to misuse. The jet must not be directed at persons, live electrical equipment or the machine itself. Do not use the machine within range of persons unless they wear protective clothes.

Do not direct the jet against yourself or others in order to clean footwear. Risk of explosion – Do not spray flammable liquids. High pressure washers shall not be used by children or untrained personnel. High pressure hoses, fi ttings and couplings are important for the safety of the machine. Use only hoses, fi ttings and couplings recommended by Gerni. To ensure machine safety, use only original spare parts recommended by Gerni. Water that has flown through back-flow preventers is considered to be non-potable.

Don't use the machine if a supply cord or important parts of the machine are damaged, e.g. safety devices, high pressure hoses, trigger gun. Inadequate extension cords can be dange rous. If an extension cord is used, it shall be suitable for outdoor use, and the connection has to be kept dry and off the ground. It is recommended that this is accomplished by a cord reel which keeps the socket at least 60 mm above the ground. Switch off and unplug the machine when leaving it unattended, when finished using it or when converting it to another function, when doing repair and maintenance.

During use of high pressure washers, aerosols may be formed. Inhalation of aerosols can be hazardous to health, for the protection against aerosols a respiratory mask of class FFP 2 or equivalent may be needed, depending on the cleaning environment.

Intended Use and Terms of Liability The Classic, Classic PG, Super and Super PG series have been developed for domestic cleaning pur poses only and for use in an upright position. Any other use is considered as improper use. ● A high pressure washer operates with different levels of pressure and cleaning detergents for various cleaning tasks and results. Always follow instructions on detergents for use, emergency and disposal. ● Do not operate the machine at temperatures below 0°C. Never start a frozen machine, never use it indoor and never cover it during use. This is considered improper and wrongful use. Use of wrongful pressure, detergent and/or applications may cause damage to machine, surfaces, material and devices. All of the above is considered improper and wrongful use. Gerni accepts no liability for any damage resulting from any improper or wrongful use.

Safety devices and their functioning The machine automatically stops when releasing the trigger. The machine will start again when reactivating the trigger. The spray handle features a locking device. When activated, the spray handle cannot be operated. The machine has an automatic self-resetting thermo protector. If the machine is overheated, the thermo protector will cut the power supply. In this case, wait for the machine to cool down. An integrated hydraulic safety valve protects the system from excessive pressure.

Precautions The electric supply connection shall be made by a qualified electrician and comply with IEC 60364-1. It is recommended that the electric supply to this machine should include either a residual current device that will interrupt the supply if the leakage current to earth exceeds 30 mA for 30 ms or a device that will prove earth circuit. ● Use motor start/delayed fuses with characteristic D according to IEC 947-2 or corresponding standards outside IEC. ● If the supply cord is damaged, it must be replaced by an authorized Gerni distributor or similar qualified person in order to avoid a hazard. ● No actions needed for adjusting machines marked with dual voltage and frequency. ● Supervise children not to play with the machine. ● The operator and any one in the immediate vicinity of the site for cleaning should take action to protect oneself from being struck by debris dislodged during operation. ● Always wear safety boots, respiratory mask, ear protection,

goggles and protective clothing during operation. ● The high pressure generated by the machine is a particular source of danger. Hold the spray lance firmly with both hands. The spray lance is affected by a kickback force and a sudden torque during operation. ● See Part 3:3 for the actual size of the kickback force. ● During transportation: Position the machine horizontally on the backside and secure with straps.

Within EU High pressure washers shall not be used nor maintained by children. The machine can be used by people with reduced physical, sensory or mental capabilities or lack of experience and knowledge if given supervision or instructions concerning use of the machine in a safe way and understands the hazards involved.

Outside EU High pressure washers shall not be used nor maintained by children or untrained people or people with reduced physical, sensory or mental capabilities or lack of experience and knowledge.
