Parts

WARNING
Do not try to modify the tool or manufacture accessories that are not recommended. Otherwise there is hazard of severe personal injury and making the warranty void.

WARNING
When assembling parts disconnect the spark plug cable from the motor, to prevent an accidental start and cause severe injury.

Assembly

Guard

• Install the guard before setting the string spool. Otherwise the guard cannot be mounted.
• Pass the guard on the curved arm end. Double-check to align the guard orifices with the mounting orifices (A).
• Secure the guard with the bolt and nut.

Shaft

• Align the safety pin (a) of the lower shaft with the middle hole in the clamp (b).
• Press the safety pin down and insert the lower shaft into the clamp.
• Release the safety pin; ensure that it engages in the hole on the upper shaft .
• Tighten the locking knob anticlockwise to secure the connection (c).

Cutting string replacement and mounting

• With the string trimmer turned off, remove the spool-retaining cap (A) turning counter-clockwise.
• Remove the empty spool. Verify it is clean and has no damaged or worn parts.
• Cut 20´ length of cutting line. Make a loop in the middle of the line and insert the loop in the spool inner hook (B). Hold the line and wind it clockwise. Double-check each end of the line is wound in its respective section (upper and lower). Do not wind too much line. After winding there shall remain a 0.2” minimum distance between the spool edge and the wound line.
• Leave approximate 6” unwound on both ends of the line and insert each one of them in the spool notches (C). This is to prevent the line to unwind while installing the spool in the brush cutter. Later on you will release the lines from their notches.
• Set back the spool in its cover passing the ends of each line through the cover orifices (D). If the line is loose or tangled in this step, wind it again in the spool and secure it in its notches.
• Set the spool cover in the axis (E) and secure the spool tightening the retention cap (A).
• Apply force and pull both ends of the cutting line outwards to release it from the notches in the upper side of the spool (G).

Auxiliary handle

• Install the auxiliary handle as shown in the figure.
• To operate comfortably move the auxiliary handle trough the string trimmer arm up to the right height.
• Tighten the screws to fix into position.

Harness

Set the harness in the handle ring to support the string trimmer on the shoulder.

Fuel supply

• Follow the safety standards for handling fuel (Page 5).
• Allow the motor to completely cool down before filling up.
• Set the string trimmer lying it down onto a flat surface as shown in the figure.
• Wipe around the fuel tank cap to prevent contamination.
• Slowly loosen the fuel cap.
• Use care to avoid spillage. Pour the fuel mix into the fuel tank.
• CAUTION Follow fuel specifications.
• Before setting back the fuel cap check and clean the joints.
• Immediately set the fuel tank cap back and tighten by hand.
• Wipe clean any fuel spills.
  CAUTION
  In a new motor and after running it for the first time it is normal that smoke emissions are present.

Start up

Starting

• Set the tool onto level ground using care the cutter head is not making contact with any obstacles.
• Set the switch in the ON position (A).
• When the motor cools down move the choke lever (B) upwards. Press and release the primer bulb (C) 6 times.
• If the motor is hot move the choke lever downwards. Do not use the primer bulb.
• Pull the starter/handle (D) quickly to start the motor. Once the motor is running do not release the starter/handle, carefully set it back to its initial position to prevent damaging it.
• Once the motor is running move the choke lever downwards.
• Let the motor run idle a couple of seconds.
• Set the harness onto your shoulder. Hold the string trimmer by both handles using both hands.
• Lift it to start cutting.
• Press the lock (E) and the throttle trigger (F) to start the cutting device.

Operation

CAUTION

• Remember that you, being the string trimmer operator, are responsible of your safety and the safety of those who are near your work area. Follow all security standards before operating the tool.
• Keep good balance with both feet firmly set on ground.
• Use the harness to support the string trimmer weight. Hold firmly the string trimmer in front of you. Set one hand in the handle and the other in the auxiliary handle to have the tool aligned to your body and pointing the cutter head 30° downwards, away from your feet.

DANGER

• Do not turn on or operate the string trimmer in any other position.
• Turn on the string trimmer and make cuts from left to right rotating your waist and keeping the tool position.
• As you cut grass the cutting thread will wear and will fall. To release more thread from the spool press the string trimmer lightly downwards to have the ground pressing the retention cap against the spool and to release more thread. 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 TRUPER 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 cleaning

• 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 TRUPER 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 TRUPER 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 TRUPER 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 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 away from children.
• Comply with all the government rules regarding safety in handling and storing fuel.
