Tips

Always use the correct fuel mixture (50:1 petrol to 2-stroke oil) to prevent engine damage. For wet cutting, connect a standard garden hose to the water feed to minimize dust and keep the blade cool. Inspect the blade for cracks or wear before each use, and ensure the blade guard is properly positioned. Allow the engine to cool before refueling, and store the saw in a dry place when not in use.
