REMOVING AND INSTALLING THE GUIDE BAR AND SAW
CHAIN
WARNING:
The saw chain is very sharp. Always wear
heavy-duty protective gloves when handling or performing
maintenance on the saw chain.
The guide bar and saw chain need to be removed when certain
maintenance procedures are performed, such as when rotating the
guide bar. When replacing old guide bars and saw chains with new
parts, always use the manufacturer's specified replacement parts.
Refer to Replacing the Guide Bar and Saw Chain.
Removing the Guide Bar and Saw Chain
1. Remove the screw and two (2) bar-retaining nuts (1/2 inch) (Fig. 11).
2. Remove the bar cover (Fig. 11).
3. Loosen the saw chain. Refer to Adjusting the Chain Tension.
4. Carefully remove the saw chain and guide bar.
5. Remove the saw chain from the guide bar.
Installing the Guide Bar and Saw Chain
1. To allow room for installation, loosen the chain tension. Refer to
Adjusting the Chain Tension.
2. Set the saw chain on a clean, flat surface and straighten out any
kinks.
3. Fit the saw chain into the guide bar groove (Fig. 12). Make sure
the cutters point in the correct direction of rotation (Fig. 12). Keep
a loop of saw chain at the back end of the guide bar (Fig. 12).
4. Hold the saw chain and guide bar together in position over the
unit. Loop the saw chain around the drive sprocket and install
the guide bar onto the bar-retaining studs (Fig. 13). Make sure
