13.1 Notes on fire protection
The device generates heat from burning fuel. Due to the ignition source (burner) and the high temperatures, increased precautions must be taken to minimize the risk of fire.

• WARNING! Never cover the device, as it might otherwise overheat.

• Keep the air inlet to the burner unobstructed and free of dirt. Reduced airflow can lead to overheating of the device. Do not operate the device near curtains or other
  objects that might come into contact with it or might block its air inlet.

• Do not operate the device near open fires or other heat sources.

• Do not operate the device near flammable objects.

• Do not operate or store the device in aggressive atmospheres, or areas where there might be combustible gases, gas-air, or dust-air mixtures.

• Do not operate or store the device in areas where combustible fumes of gasoline, solvents, or thinners are present.

• Portable fuel tanks must be installed and operated in accordance with the technical rules for the storage of liquid and solid hazardous substances in stationary containers
  and filling and emptying installations for non-stationary containers (TRGS 509).

• Do not install or operate the device in atmospheres containing oil, sulfur or alt vapors.

13.2 Fuel
NOTICE
Admissible fuel
The device must only be run with diesel or petroleum.
The use of a suitable fuel (see Technical data and factory settings [ 40]) minimizes the risk of fire and explosion. Never use benzene, paint stripper, alcohol, or other highly
flammable fuels.
At temperatures below 5°C, use only fuels that are stable up down to a temperature of approx.-20 °C, such as winter diesel or polar diesel conforming to DIN EN 590.
13.3 Instructions for battery operation

• Before using the battery, read the instructions and warnings attached to the battery and the charger.
• Never operate the device with a damaged or defective battery.
• Protect the battery from impacts, and do not drop it.
• Do not open or disassemble the battery.
• If you notice that the battery life is much shorter than expected, shut down the device without delay. Otherwise, there is a risk of overheating or even an explosion.
• Never short circuit the battery:
• Ensure that the battery contacts do not come into touch with an electrically conductive material.
• Do not store the battery together with metal objects such as nails, coins, etc.
• Keep the battery dry at all times.
• A short circuit in the battery leads to very high currents, which in turn can cause overheating, damage to the battery, and injury from burns.
• Do not expose the battery to temperatures of 50 °C or higher.
• Do not incinerate the battery, even if it is damaged or can no longer be charged. When set alight, the battery might explode.
• In case of electrolyte in the eye, rinse the eye with clean water and immediately seek medical attention. Otherwise, there is a risk of permanent sight loss.
• Lithium-ion batteries are subject to the statutory regulations that govern hazardous substances. For commercial transport, e.g. by courier service, etc., the packaging and labeling must meet specific requirements. Observe the applicable statutory regulations. Do not tape over or otherwise cover exposed contacts, and pack the battery so that it cannot move inside the packaging.
• Strictly follow the statutory regulations for the disposal of batteries.
• Only use the battery for products for which it has been approved by HEYLO. Do not use the battery in products for which it has not been approved, as this can lead to fire, overheating, explosion, or electrolyte release.

Maintaining maximum battery life

• Recharge the battery before it has been fully discharged. Regularly check the charging level indicated by the battery charge indicator on the battery. If the battery is low, switch off the device and recharge the battery in the charger.
• Charge the battery at room temperature between 10 and40°C. If the battery is hot, allow it to cool down to this temperature. If the battery is colder than 10°C, bring it to room temperature before charging it.
• If the battery is not to be used for more than six months, charge it fully before putting it into storage.

13.4 Protection of the environment
Safety-conscious and forward-looking action on the part of the personnel helps prevent damage to the environment.
To protect the environment, observe the following general rules:

• Never release environmentally hazardous substances released into the ground or the sewerage system.
• Observe the statutory regulations for waste prevention, disposal, and recycling.
• Always store environmentally hazardous substances in appropriate containers, and label the containers accordingly.

Design and scope of delivery Illustration 17: Device design (front side)

Illustration 18: Device design (operating side)

The scope of delivery includes:

• Infrared oil heater
• Handle
• Battery
• Charger
• Power cord
• Operating manual

Mode of operation
The device is a radiation heater with an oil burner. The device can be electrically powered by a battery or from the power mains.
The fuel is taken by the oil pump from the tank,  compressed to operating pressure, and fed to the nozzle.  The nozzle injects the fuel as a mist into the combustion chamber where it ignites. The result is a flame that, together with its combustion gases, heats the combustion chamber and the heating plate.
The exhaust gases are fed out of the device. The heating plate provides uniform radiation heat. The heating plate is protected by a cover and a protective grille to prevent direct contact with flammable materials.
The device is switched off and on with the device switch.
Operation with room thermostat
The device can be run in conjunction with a room thermostat so that it is operated on the basis of the actual room temperature.
