Adjusting the Belt Tension Through the Trimmer
Control Cable
WARNING! Before performing any maintenance procedure, stop the engine and disconnect the spark plug wire.
Important! Before making any adjustments to the trimmer control cable, check that the belt is mounted on the correct side of the idler pulleys (see Figure 24), and is not frayed, worn or stretched.
Tools needed: You will need two ½″
If the trimmer head stops spinning when the bail bar is engaged and the machine is operating under a heavy load, the belt may be too loose. In this case, you may need to adjust the trimmer control cable to put more tension on it. The adjuster is located on the right handlebar, just above the throttle control lever.
To increase tension on the belt:
1. Loosen the upper control cable
1
adjustment nut, leaving about ⁄8″ of space between the nut and bracket(Figure 26).
2.Gently grip the metal end of the black cable with pliers, making sure you DO NOT crimp it. At the same time, tighten the lower nut until it is flush and snug against the bracket (Figure 27).
Note: If the trimmer head keeps spinning after releasing the bail bar, the belt may be too tight.
