7.The torque specs are

•22-40 foot-pounds [30-55 Nm] for the shield fasteners,

•27-33 foot-pounds [36.6-44.7 Nm] for the drive pulley mounting bolt, and

8.Check the routing of the drive belt. Make sure the drive belt is inside of all belt guides and that the belt is not twisted. (See Figure 20)

IMPORTANT: Test the drive system. Start the engine and move the throttle control to the FAST position. Engage and disengage the trimmer head several times. When disen- gaged, make sure the trimmer head completely stops when resting on the ground. If the trimmer head continues to rotate, take the trimmer to an authorized Service Center.
