Maintenance

Cleaning the air filter

• Remove the air filter cap pressing the sides and lifting it.

• 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.

General cleaning

• Clean and unblock all the starter unit ventilation slots

with a brush when necessary.

• Like ways, 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.

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 you eliminate the fuel

residues and will avoid gum forming and damaging the fuel

system.

• Clean thoroughly.

• Store the tool in a ventilated space, away from corrosive

agents like garden chemical substances or deicing salts. Also

store away from children.

• Comply with all the government rules regarding safety in

handling and storing fuel.

Carburetor adjustment

• We recommend making carburetor adjustments in a

Authorized Service Center.

• A wrong adjustment can damage the motor and make

the warranty void.

Fuel filter

• Check the gasoline filter frequently.

• If the filter is dirty, replace it.

• If the gas tank interior is dirty rinse it with gasoline.

Spark plug replacement

ENGLISH

CAUTION

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.

• 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.
