MAINTENANCE
6.Lay out the saw chain in a loop and straighten any kinks. The cutters should face in the direction of chain rotation. If they face backwards, turn the loop over.
7.Place the chain drive links into the bar groove as shown in figure 46.
8.Position the chain so there is a loop at the back of the bar.
9.Hold the chain in position on the bar and place the loop around the sprocket.
10.Fit the bar flush against the mounting surface so that the bar studs are in the long slot of the bar.
Note for UT10570: When placing the bar on the bar studs ensure that the adjusting pin is in the chain tension pin hole.
11.Replace the outer guide bar plate ensuring that the bar pin groove is at the bottom with the upper and lower edges angled away from the guide bar.
12.Replace the clutch cover and bar mounting nuts.
13.Tighten the bar mounting nuts finger tight only. The bar must be free to move for tension adjustment.
