Tensioning the Blade Drive Belts
Figure 34: Blade Drive Belts
1.Inspect the belts for fraying, stress cracks, and/or breakage and replace immediately when damaged.
2.Test the belt tension. Proceed to step 3 if the belts need tensioning (refer to Appendix C for the proper tension setting). Operate the saw as needed if no tension adjustments are required.
3.There are four engine/motor base screws; two on the side of both bases. Loosen the nut on each screw.
Figure 35: Engine/Motor Base Screws
4.Turn the tension bolt at the front of the engine/motor clockwise to tighten the belts. Readjust the tension bolt as necessary to reach the required tension setting. DO NOT exceed the manufacturer’s tension setting.

5. Retighten all four engine/motor base nuts.
Replacing the Blade Drive Belts
1.There are four engine/motor base screws; two on the side of both bases. Loosen the nut on each screw.
2.Turn the tension bolt at the front of the engine/motor counterclockwise to loosen the belts. DO NOT remove the bolt.
3.Remove the belts from the crankshaft sheave and from the blade shaft sheave.
4.Loop and align the new belts around the blade shaft sheave, and then pull them up and loop and align them around the crankshaft sheave.
5.Turn the tension bolt at the front of the engine/motor clockwise to tighten the belts (refer to Appendix C for the proper tension setting). Readjust the tension bolt as necessary to reach the required tension setting. DO NOT exceed the manufacturer’s tension setting.
6.Retighten all four engine/motor base nuts.
