Trimmer Presentation Outline

1. Welcome & Introduction
    A. Itinerary and set expectations – Ask the group what they do with the equipment and discuss some of the challenges they have with    equipment and operators. Technical and safety.

2. Safety/ PPE
    A. Throttle Interlock – must be depressed before throttle can be activated.
    B. Check for Low Vibration – Isolates engine from shaft which minimizes vibration to the operator’s hands allowing a safer, more comfortable, and productive experience.
    C. Cut away trimmer head guard – Protects operator from thrown objects and allows for easier trimming around flowers.
    D. Eye and ear protection
    E. Visor (Plexiglas or Mesh) for extreme conditions or brush cutting.
    F. Spark arrester is in position and clean.

3. RDT - Equipment Pre-Inspection and Maintenance
    A. Trim head is full of line, eyelets are not worn or missing.
    B. Trimmer guard is in place and not cracked.
    C. Cutter on trim guard is in place and functional.
    D. Bump knob not worn out.
    E. Gear head is greased.
    F. Check all other guards to insure they are not broken.
    G. Rubber padded handles are not torn.
    H. Gas tank is full. See through fuel tank.
    I. Enclosed throttle cable and protected carb. – no damage can occur.
    J. Air cleaner is free of debris, clean and oiled.
    K. Spark plug properly gaped and free of carbon.
    L. Adjustable carburetor – allows full adjustment to fine tune the engine performance.
    M. Trim head not moving in and idle position.

4. Ergonomics
    A. 7 degree offset handle – allows the wrist to remain straight during operation for comfort and less fatigue.
    B. Adjustable handle – machine adapts to multiple operators for comfort.
    C. Inverted Flywheel – centralizes the flywheel rotation to improve balance and comfort for less fatigue. Flywheel blows back over engine to cool it and displaces smoke and smell from the operator.
    D. 35 degree gear box angle – allows the trimmer head to remain flat to the ground versus traditional 30 degree competitive angles. Difference between brush and clearing saw angles and shaft length.
    E. Rubber padded handles, adjustable thumb screw loop handle, bottom engine guard, front engine fore arm guard – durability comfort to increase productivity.
    F. Have the proper shoulder straps or Harness Systems.

5. Starting and Operation Procedure
    A. Proper fuel mixture.
    B. Visual safety and RDT inspection.
    C. Air purge with choke – bulb displaces air from the fuel line for easy, quick, and consistent starting without flooding the engine.
    D. Engine should accelerate to full RPM quickly without hesitating.
    E. Should be operated at full throttle when ever possible.

6. Application
    A. Power To Weight – high power with low weight to increase productivity.
    B. Plan & assess the job for safety & productivity.
        1) Hazards & obstacles
            i. Pick up all debris and search job site for any hidden obstructions such as glass, cans or other items that may become a projectile or could cause damage other people.
            ii. Insure that trim area is clear of other people. (Show how it will take a small pebble and turn it into a projectile)
        2) Trim line size / .080, .095, .105 – Line welding…
        3) Trimmer line length verses - heat and RPM.
        4) Engine size
        5) Trim head / Barrier Bar Kit with Blade
    C. Trim in the direction so the debris does not fall back on the operator.
    D. Proper techniques. Keeping the bump knob off ground.
    E. Smooth and easy movements while trimming.

7. Adaptability
    A. Different style trim heads
    B. Different style trim line
    C. Barrier bar kit
    D. Pole saw gear head
    E. Clean sweep gear head
    F. Split boom style trimmers

8. Troubleshooting Notes
    A. Engine will not start
        1. No fuel, improper starting procedure – i.e. above
        2. Flooded
        3. Air cleaner clogged
        4. Spark arrester clogged
        5. Spark plug fowled
    B. Machine vibration
        1. Missing parts, one line out – instead of two, engine loose from mounts
