11.Open the fuel shutoff valve and check for leaks.
Storing
Complete the tasks listed below prior to storing the saw for longer time frames:
•Lower the saw completely to remove any strain on the lifting mechanism.
•Turn off all switches and controls (including the master disconnect).
•Remove the battery from the saw and store it in a proper location, out of reach from children.
•Disconnect the water supply hose from the blade guard, open the water valve, and blow compressed air through the water supply fitting to drain water from the water lines/hoses.
•Clean the blade guard water tubes using a wire brush and rinse with a hose.
