Installing the guide bar and chain
WARNING. The chain has sharp edges. Use work gloves for safety.
1.Pull the front guard (9) towards the rear of the saw until there is a “click” to make sure that the chain brake is released.
2.Remove the two chain drive cover nuts (5) with the double ended wrench (28) and remove the chain drive cover (4).
6.Place the chain (2) around the drive sprocket wheel (25) with the chain links in the direction shown on the bar and fit the chain around the guide bar.
7.Fit the chain drive cover and fasten the two nuts (5), finger tight.
8.With the guide bar pointing upwards, tighten the chain tensioner screw (3) until the links of the chain just touch the bottom edge of the guide bar.
3.Remove the spacer (26) and discard.
4.Fully loosen the chain tensioning screw (3).
5.Place the guide bar (1) in position over the two threaded studs with the chain tensioning pin (27), in the hole in the guide bar.
9.With the guide bar pointing upwards, tighten drive nuts.
10.Check that the chain can be smoothly pulled around the guide bar by hand and that it maintains contact with the guide bar, top and bottom.
To check tension, rotate the chain to its tightest condition then suspend a 0.9kg weight from the chain at the mid point of the underside of the bar. The maximum distance between the driving links and the bar should be 6.5mm.
