2. Safety Instructions

WARNING: Always observe basic safety precautions to reduce the risk of fire, electric shock, and personal injury.

• Always ensure the machine is shut down and the battery pack is removed before performing any maintenance, cleaning, or when the tool is not in use.
• Operate the heat gun only in well-lit areas.
• Do not extend your body too far; always maintain a firm and balanced stance.
• Do not aim the nozzle at anyone in the work area. The hot air can cause severe burns.
• Avoid using the heat gun on wet surfaces or in rainy conditions. This tool is for indoor storage and should not be exposed to rain or adverse weather, especially thunderstorms.
• Do not block the air inlet or the hot air outlet during operation. Blocking airflow can lead to overheating and potential fire hazards.
• Do not use conical nozzles smaller than the original or attempt to connect additional small-diameter hoses, as this can cause motor damage and serious injury.
• Do not use the heat gun for inflating balloons, rubber boats, or similar items, as this can cause the fan to break.
• Avoid operating the heat gun near open windows or in areas where hot air could cause unintended damage.
• To prevent accidental start-up, ensure the switch is in the OFF position before connecting or removing the battery pack, or when handling the tool.
• Do not insert fingers or other objects into the air inlet or hot air outlet.
• Always wear appropriate personal protective equipment, including safety goggles, gloves, and a dust respirator if working with materials that produce fumes or particles.

5. Setup

5.1 Battery Installation and Removal

1. To install the battery: Align the battery pack with the slot in the base of the heat gun and slide it in until it clicks securely into place.
2. To remove the battery: Press the battery release button (usually located on the battery itself) and slide the battery pack out.

5.2 Battery Charging

Use only the specified charger for your Yofidra 18V battery. Ensure the battery is fully charged before first use.

1. Plug the charger into an AC outlet.
2. Insert the battery pack firmly into the charger.
3. During charging, the charging lamp will light up.
4. When charging is complete, the charging lamp will start flashing quickly (or indicate full charge as per charger design). An internal electronic switch prevents overcharging.
5. If the battery pack is warm (e.g., immediately after heavy use), charging may not start immediately. The charger will wait until the battery cools down before beginning.
6. For new batteries or those unused for a prolonged period, a protective charging cycle may occur, which takes longer to fully charge the battery.
