The guard blade will cut the remaining thread. At this moment stop pushing the string trimmer against the ground to stop spending more thread.
• To cut brush or tall grasses make it gradually. Do not try to cut in one pass from its base because residue could clog the cutting head or make you loose control over the string trimmer.

Maintenance

• Before inspecting, cleaning or servicing the tool, turn off the motor. Wait for all the moving parts to stop. Disconnect the spark plug cable and separate it from the spark plug. Otherwise, you could be severely injured and the equipment could get damaged.

General cleaning

• Clean and unblock all the starter unit ventilation slots with a brush when necessary.
• In the same way, periodically clean the motor cylinder wings and the fan wings to remove dirt. Not doing it will cause the motor to overheat and get damaged.

Cleaning the air filter

• Remove the air filter cap loosening the cap knob.
• Remove the air filter.
• Depending of the time it has been used you can give a superficial cleaning to the filter by only tapping it against a flat surface to remove most of the particles.
• You can also blow the filter with compressed air. Do it in both sides.
• For a more complete cleaning wash the filter in lukewarm soapy water. Rinse it and let it dry before installing it back in the tool.
• Install back the air filter verifying it clicks in place.
• Clean the air filter as frequently as necessary to keep it always clean. Otherwise the motor performance will diminish.

Fuel filter

• Check frequently the gasoline filter.
• If the filter is dirty, replace it.
• In the gas tank interior is dirty rinse it with gasoline.

Carburetor adjustment

• We recommend making carburetor adjustments in a Authorized Service Center.
• A wrong adjustment can damage the motor and make the warranty void.

Spark plug replacement

• The motor uses a TORCH L8RTC spark plug with an electrode gap of 0.025” Replace the spark plug once a year with a similar one.
• With a totally cold motor, loosen the worn spark plug turning left with a spark plug wrench and remove it.
• Insert the new spark plug and tighten to the right by hand. Tighten it half a turn more with the key included.
• CAUTION Use care not to damage the spark plug thread. Otherwise the motor will be seriously damaged.

Exhaust and muffler cleansing

• The exhaust and muffler can be clogged with carbon deposits, depending on the type of fuel, the amount of oil used and/or the conditions the tool is used. If noticing loss of power you should remove the deposits to restore performance. Go to a Authorized Service Center to have this service made.
• The muffler is equipped with an anti-spark screen inside the muffler. After being used long periods of time the screen gets dirty and needs to be replaced. Go to a Authorized Service Center to have it replaced.
• CAUTION Check constantly that the muffler has the fasteners secured and that there is no damage or corrosion. If finding leaks, stop the tool and immediately go to a Authorized Service Center to have it repaired.

Tool storage
If storing the tool a month or more, be aware of the following:

• Drain all the contents in the fuel tank into an approved gasoline container. All the remaining fuel should be used again in other equipment with a two-cycle motor with a ratio of 50:1.
• Run the motor until the rest of the fuel is consumed and the motor shuts off by itself. This way all residual fuel will be eliminated and will prevent oil grums deposit build up that could damages the fuel system.
• Clean thoroughly.
• Store the tool in a ventilated space, away from corrosive agents like garden chemical substances or deicing salts. Also away from children.
• Comply with all the government rules regarding safety in handling and storing fuel.

Troubleshooting

• There is no fuel.
• The motor is choked.
• The starter jack is pulling with more difficulty than when new.| • Check the spark.  Remove the motor cover.  Remove the spark plug from the cylinder. Connect the spark plug cable and set it on top of the motor cylinder with its metal part touching the cylinder. Pull the starter 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 primer bulb. If no fuel is showing it means that the fuel supply primary system is blocked. Contact a Authorized Service Center. If the primer bulb fills with fuel, it means the motor is choked.
• With the switch off, remove the spark plug. Move the choke lever upwards and pull the starter handle 15 to 20 times to eliminate the fuel excess in the motor. Clean the spark plug and reinstall. Follow the normal
starting procedure (consult page 8).  If the motor does not start, move the choke lever downwards and repeat the starting procedure. If the motor is still not running, repeat the procedure but this time using a new spark plug.
• Take the tool to a Authorized Service Center.
The motor starts but it is not accelerating.| • The motor needs a few minutes to warm up.| • Allow the motor to warm up completely.  If the motor is not accelerating after three minutes contact your Authorized Service Center.
The motor starts, but it only runs at high speed with the choke at half position.| • Carburetor needs adjustment.| • Take the tool to a Authorized Service Center.
The motor is not gaining full speed and has too much smoke emissions.| • Check the oil/fuel mix.
• The air filter is dirty.
• The anti spark guard screen is dirty.| • Use new fuel and the right oil mix for two-cycle.
• Clean the air filter. See page 10.
• Clean the anti spark guard screen. See page 10.
