Troubleshooting - Truper DES-330 Instructivo

Grass trimmer storage
When the tool is stored one month or longer consider the following:
• Drain the fuel tank contents into a gasoline designated container. All the remaining fuel shall be re-used in other
equipment using 2-stroke motors with 40:1 ratio.
• Run the motor until burning the rest of the fuel and it off. This way all residual fuel will be eliminated and will prevent
gum deposit build up that damages the fuel system.
• Clean the tool thoroughly.
•Store the unit in a ventilated area, away from corrosive agents such as garden chemical products or de-icing salt. Keep it
away from the reach of children.
• Obey all the government regulations concerning fuel handling and management.

Troubleshooting

Solution
• 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 metallic side touching the cylinder. Pull the starter handle
and watch the spark in the spark plug electrode. If there is no spark, repeat
the test with a new spark plug.
• Press the primer bulb until the fuel is visible in the choke. If the fuel is not
visible, it means that the fuel primary supply system is blocked. Contact a
Authorized Service Center. If the primer bulb is filled
with fuel, it means the motor is flooded.
• With the switches in the OFF position, remove the spark plug. Set the
choke lever downwards and pull the choke lever 15 to 20 times to
eliminate the excessive fuel from the motor. Clean the spark plug and set
it back. Follow the normal start up procedure (see page 9). If the motor is
not starting, move the choke lever downwards and repeat the starting
procedure. If the motor is still not starting, repeat the procedure with a
new spark plug.
