 The design of your machine is for trimming and mowing grass, weeds, and other growth as specified in this manual. Do not

use it for any other purpose as it could cause serious injury.

 Contact with internal rotating parts will cause serious personal injury. Never put hands, face, feet, or clothing under the

mower deck or discharge opening at any time.

 Before performing any adjustments to the trimmer cords or any other procedure or inspection, stop the engine, wait five

minutes to allow parts to cool. Disconnect the spark plug wire, keeping it away from the spark plug.

Chapter 3: Operating the TRIMMER/MOWER

Before Starting the Engine

Note: The Fuel and Oil Fills on the 6.75 and 7.25 Electric Start models are on

opposite sides from what is shown in figure 10.

1. Check the oil level every time you use the TRIMMER/MOWER (Figure 10).

2. Check the fuel level.

3. Remove any debris buildup from the top of the Engine and the underside of

the machine.

Note: See the Engine Manual for more detailed and specific information on

operating the Engine.

Manual Starting

Note: You may use these starting methods with both Manual and Electric-Starting

models.

1. Push the Throttle Control Lever all the way forward to the Run

position

(Figure 10).

Note: The 6.75 EXi, 7.25 EXi, and 8.75 models do not have a Choke or Primer Bulb.

Step 2 can be ignored.

2. For 6.75 Electric Start models only, push the Primer Bulb in and completely

release it, lifting your finger and letting it pop back to its original position.

Repeat three to four times. For 7.25 Electric Start models only, move the

Choke Lever left to the CHOKE position (Figure 11).

Note: “Priming” or “Choking” the Engine is usually not necessary when restarting a

warm Engine. In cool weather, you may need to repeat the priming operation.

3. Grasp the Recoil Starter Handle and slowly pull until you feel resistance. Let the cord retract a little bit and then pull the cord

rapidly to start the Engine. One or two pulls usually starts the TRIMMER/MOWER.

Note: Do not engage the Bail Bar (Trimmer Head Control) until after the Engine has started.

4. For the 7.25 Electric Start models only, once the engine has started, move the Choke Lever right to the RUN position.

It is important for proper operation to keep the top of the engine clear of

grass and debris at all times so the engine can pull air through to stay cool. If

the top of the engine is clogged then the engine could overheat causing

engine damage.
