Frequently Asked Questions - Pro 160.2 Gerni

How do I connect the pressure washer to the water supply?

Ensure the water supply is turned on and the hose is connected to the inlet. Use a standard garden hose with an adapter if needed. The water flow must be at least 500 l/h.

Can I use detergent with the Gerni Pro 160.2?

Yes, attach the foam nozzle and fill the detergent tank with a suitable pressure washer detergent. Do not use bleach or acidic cleaners.

What is the maximum water temperature for operation?

The maximum water temperature is 40 °C (104 °F). Hotter water may damage the pump seals.

How do I store the pressure washer after use?

Disconnect water and power, press the trigger to release pressure, and store in a dry, frost-free location. Drain any remaining water from the hoses.

Why is the pressure washer not starting?

Check the power supply, ensure the thermal overload protection hasn't tripped, and verify the water supply is on and the trigger is pressed to release air.

How often should I replace the pump oil?

For the Pro 160.2, the pump is sealed and does not require oil changes. No maintenance is needed for the pump unit.

Can I use an extension cord?

Yes, use a heavy-duty extension cord (min 1.5 mm² cross-section) suitable for outdoor use, and keep it as short as possible to avoid voltage drop.

What safety precautions should I take?

Always wear protective eyewear, never point the nozzle at people or pets, and ensure the surface is not damaged by high pressure. Use the trigger lock when not spraying.

How do I clean the nozzle if it becomes blocked?

Turn off the washer, disconnect the trigger gun, and use a thin wire or the cleaning needle provided to clear the nozzle orifice. Reattach and test.

Where can I find spare parts or repairs?

Contact an authorized Gerni service center. Common parts like nozzles, hoses, and seals can also be ordered online through spare parts distributors.

USER MANUAL Pro 160.2 Gerni

Warning symbol: black exclamation mark inside a triangle (no text or numbers)

User Guide

Green Gerni 1602 water heater with black and white body, no visible text or symbols on the device itself.

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

Part 1:3 - 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.

WARNING

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, fittings and couplings are important for the safety of the machine. Use only hoses, fittings 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 PRO-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 re-activating the trigger. The spray handle features a locking device. When activated, the spray handle cannot be operated.

The machine has an automatic self-resetting thermal protector. If the machine is overheated, the thermal 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.
• 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.
