Removing the Blade
CAUTION
•DO NOT remove a blade with the engine/motor running.
1.Remove the blade guard or pivot the front of the guard 180° (fully upward) to gain access to the blade flanges. Note: Failure to fully pivot the guard may cause serious injuries.
2.Slowly lower the blade until it touches the ground.
3.Remove the blade shaft nut using the wrench.
4.Carefully remove the outer flange from the inner flange alignment pinhole and blade, and then remove the flange from the blade shaft.
5.Remove the blade from the blade shaft. Place the blade in an appropriate storage location.
6.Inspect the nut, outer flange, and inner flange for damages and clean, repair, or replace as necessary.
7.Fit the outer flange back onto the blade shaft.
8.Place the blade shaft nut onto the blade shaft and tighten by hand to secure the inner and outer flange together.
9.Replace the blade guard or pivot the front of the guard down and over the blade to secure.
Blade Guard
WARNING
•DO NOT operate the saw with the blade guard raised or removed.
•DO NOT install or remove the blade guard with the engine/motor running.
•Blade exposure should not exceed 180° while cutting.
•Always pivot the front of the blade guard 180° (fully upward) so the guard does not swing down unexpectedly, causing serious injuries.
The blade guard shields the blade and must always be in place when operating the saw. Inspect the blade guard and its water tubes prior to starting the saw. Clean, repair, or replace damaged components immediately. Note: Always use a blade guard that corresponds with the blade size.
Installing the Blade Guard
1.Face the front of the blade guard forward and fit the tapered mount on the side of the guard over the tapered blade guard mount on the frame.

2.Connect the water supply hose to the blade guard. Note: Keep the water hose, when cutting on the left side of the saw, away from the muffler assembly to prevent hose damage.
