Installation

1. Insert the wheel axle into the corresponding hole of the lower tube frame. Place bushings G at both ends of the axle, then slide the wheel F over the wheel axle H. Secure the wheel by placing the wheel cap E on the end of the axle.
2. Position the product body onto the lower tube frame B, ensuring that the 4 holes in the handle frame align with the corresponding 4 holes on the lower tube frame.
3. Insert screws J into the holes, place flat washers D under the lower tube frame B, and tighten the hexagonal screw C securely.
4. Insert the remaining screws into the holes and tighten them using a screwdriver, following the same procedure.

Preparation before operation

NOTE

• Never use highly volatile fuels such as gasoline.
• Only refill the fuel tank when the product has stopped running and the flame has extinguished.
• Use only No. JIS1 kerosene or frost-resistant light diesel. Do not use degraded or impure kerosene or diesel.
• Ensure the fuel tank filter is installed when filling the tank.
• If kerosene or diesel comes into contact with the skin, wash immediately with soap to prevent potential skin irritation.

- The burner surface remains very hot after the flame goes out. Do not touch it or allow the oil pump to contact the burner to prevent burns or injury.

How to fill the fuel tank when empty:

1. Ensure the power plug is disconnected from the power source and that the power switch is in the OFF position "0".
2. Place the product on stable, level ground. Remove the fuel cap and fill the fuel tank, ensuring the fuel filter is properly installed. Do not overfill—refer to the full level position as indicated in the figure.
3. Check for any water or debris in the fuel tank and clean it if necessary to ensure proper operation.
4. Fill the tank with kerosene or diesel using an oil pump, ensuring the fuel filter is in place. After filling, turn the cap clockwise and tighten securely.

Fill the fuel tank (see the figure below):

When there is some fuel (Kerosene or Diesel) in the tank:

ATTENTIONS

• Only inspect the appliance after the flame has extinguished and the power plug has been disconnected from the power source.
• Before ignition, ensure there is no oil leakage. If oil leakage is detected, do not use the appliance and contact your dealer for assistance.
• Check the interior of the fuel tank, and if there is water or debris inside, clean the tank before further use.

Operation

WARNINGS

• Ensure the fuel tank has enough fuel before ignition.
• Keep a safe distance from the heating part after ignition. Maintain a minimum distance of 3 meters in front of the hot air outlet, 2 meters above, and more than 2 meters on the left and right sides (refer to the figure below for safety distance).
• Stop using the appliance immediately if smoke or strange odors are detected.

• Ensure the product is properly ignited before leaving it unattended.

• Safety distance
  

Insert the plug into the socket and set the power switch to position "1". The indicator light will turn on, and the product will ignite automatically if the set temperature is higher than the ambient temperature, as displayed on the LED digital temperature display.

If the product does not start, turn the power switch to "0" and then back to "1". If the product still fails to start after three attempts, please contact your dealer for assistance.

ATTENTION While the product is operating, ensure the floor or ground beneath it does not overheat to prevent the risk of fire.

Flame Out Procedure

1. When shutting off the product, ensure the flame is fully extinguished before leaving the appliance.

2. Set the power switch to position "0", wait for the fan to stop running, and the indicator light to go off. Then, remove the plug from the socket.

Safety Devices

- Flame-Out Protection: The product uses a photocell to monitor the flame in the burn chamber during normal operation. If the flame goes out, the photosensitive resistor's resistance will increase significantly, causing the system to cut off the Electrovalve Assembly and automatically stop the fuel supply.

- Electrical Power Breakdown Protection: In case of a power outage, the product will stop functioning without the need to unplug it. Once the power is restored, the indicator will light up, but the product will not resume operation automatically. You must press the power switch to restart the product.

Description of working principles:

To begin, open the fuel cap and add kerosene or diesel to the tank, then securely replace the fuel cap. Plug the power cord into the socket and turn the power switch to the "1" position. The motor will start, and the digital temperature display will light up. The left display shows the set temperature, and the right one shows the room temperature. When the set temperature exceeds the room temperature, the product will ignite automatically, and the spark plug will start the ignition process.

This product is equipped with an electric air pump, which forces air through the air line connected to the fuel intake, then through a nozzle in the burner head. As air passes the fuel intake, it draws fuel from the tank into the burner nozzle, where the fuel-air mixture is sprayed as a fine mist into the combustion chamber.

A fast-turning fan blows air into the system:

1. Air enters the flame steady plate and burner, providing additional oxygen to ensure efficient combustion, while also carrying heat from inside the burner to the outside.

2. Air passes through the heat insulation layer to prevent the burner surface from overheating by removing excess heat.

The spark plug stops working after 12 seconds once ignition is successful.

Troubleshooting

Trouble Analysis

Before sending the product for repair, please check the following common occurrences that are not actual faults:

Problem	Reason
Odor, smoke, or spark emitted during first use	This is normal. Air and dust mixed in the combustion process will cause this. Wait for some time, and it will disappear.
Ignition issues, strange sounds, odor, or white smoke when first used or after fuel runs out	Air is mixed in the fuel line. This issue will resolve itself once the air is pushed out of the pipe.
Strange sounds during ignition or flame out	These noises are caused by the expansion and contraction of the product's metal parts. This is normal.
Fire or sparks appear at the outlet during ignition	Fuel and air from the previous use remain in the oil pipe, causing improper fuel-air mixing and non-continuous burning. Sparks may also be caused by residual carbon powder, which is normal.

These are common conditions when using this product and do not necessarily indicate a malfunction.

This guide provides solutions for common issues with your product, allowing you to troubleshoot before seeking professional assistance.

Maintenance

NOTE

• Always turn off the product and unplug it from the power source before performing any maintenance.
• Never perform maintenance while there is fuel in the tank.

Check the fuel tank

If there is waste or water in the fuel tank, it is essential to clean and drain the tank. Follow these steps to drain the fuel tank (see the figure below for guidance):

1. Place the product on a stable working surface and position an oil container beneath the fuel tank.
2. Using a spanner, loosen the drain screw to release the water and waste from inside the tank.
3. Once the tank is fully drained, tighten the drain screw securely and wipe away any remaining water or oil to ensure the area is clean.
