Turn the saw chain tension adjusting screw (Figure 5, Item 2) until the proper tension is achieved, as follows:
Pull the saw chain (Figure 5, Item 3) away from the bar (Figure 5, Item 4) using approximately 1 lb (4.4 N) of force. The
clearance between the chain and bar should be approximately 1/8 in.(3.2 mm).
3.
Hold the bar (Figure 5, Item 4) hose up and tighten the two bar flange nuts (Figure 5, Item 1) 150 lb-in (16.9 Nm).
4.
Check the chain tension again.

Rotate the chain around the bar manually. If you hear a clicking noise, the chain drive links are hitting the bar. Repeat the
Adjusting Chain Tension procedure (Figure 5).
