Do not travel over loose materials such as gravel or mulch with the trimmer head spinning.

  • Page 4: Operating The Mower Safely

     While using the DR TRIMMER/MOWER, do not hurry or take things for granted. When in doubt about the equipment or your surroundings, stop the machine and take the time to look things over. Make sure that you have 100% control of the mower at all times.

    Using the PTA™ (Parallel Trimming Action) - SPRINT and PRO models only Your DR TRIMMER/MOWER’S PTA feature allows you to move the machine in a straight line while the Trimmer Head is both pivoted and tilted to the left for better access to fence lines and other obstacles. PTA allows you to trim in difficult areas without having to pull the machine back and forth.

  • Page 14: Engaging The Pta

    Cutting Cords also tilt slightly in PTA mode so you can edge and trim along gardens, paths, and driveways (Figure 16).

  • Page 18 Windrows The DR TRIMMER/MOWER Cutting Cords cut even tall grass in just one pass, so you can collect clippings and leaves for mulch without raking. The machine ejects cut material to its right side, so you can use it like a lawn broom to make windrows for easy clean-up.

  • Page 27 If the machine will not drive forward: Grasp the Lower Section of the Cable Adjuster with one hand and hold firmly. Turn the Upper Section of the Cable Adjuster clockwise so that the Adjuster is lengthening or turning apart.

  • Page 28: Charging The Battery

    Operate the Trimmer Engine for at least 45 minutes to maintain proper Battery charge. If the Battery loses its charge, you will need to use a trickle Charger (like the DR Battery Charger) to recharge it. The Charger should have an output of 12 volts at no more than 2 amps.
  • Page 29  Never store the DR Trimmer/Mower with fuel in the fuel tank inside a building where ignition sources are present, such as hot water and space heaters, clothes dryers and the like. If you are going to drain the fuel tank, do this outdoors. Allow the engine to cool before storing in any enclosure.
  • Page 30  If your DR TRIMMER/MOWER will be idle for more than 30 days, we recommend using a gas stabilizer. This will prevent sediment from gumming up the Carburetor. If there is dirt or moisture in the gas or Tank, remove it by draining the Tank.
