Gas Brushcutter Storage

In the event of storing the Gas Brushcutter for one month or longer, bear in mind the following considerations:

• Drain all the fuel tank contents into an approved gasoline container. All the remaining fuel can be re-used in another tool that uses 2-stroke motor with a 50:1 ratio.
• Start the motor until the rest of fuel is consumed and the motor shuts down. This will eliminate the fuel residues and will prevent gum formations that damage the fuel system.
• Clean the Gas Brushcutter thoroughly.
• Store the unit in a well-ventilated space, away from corrosive agents such as garden chemical products or de-icing salts. And away from children’s reach.
• Observe all the government rulings concerning safety in management and storing fuel.

Troubleshooting

• There is no spark.
• There is no fuel.

|

• Check the spark. Remove the motor cover. Remove the spark plug from the cylinder. Connect the spark plug cable and set it onto the motor cylinder, with the metal part touching the cylinder. Pull the jack-line and observe the spark in the spark plug electrode. If there is no spark, repeat the test using a new spark plug.
• Press the starter choke until fuel is visible in the bulb. If fuel is not visible, it means the primary system in the fuel supply is blocked. Contact a . Authorized Service Center. If the starter choke is filled with fuel, the motor is flooded.
• With the switch off, remove the spark plug. Move the choke lever downwards and pull the jack-line 15 to 20 times to eliminate excessive fuel from the motor. Clean the spark plug and set it back in place. Follow the normal starting procedure (see page 9). If the motor is not starting, repeat the procedure using a new spark plug.
