DO NOT install or run the chain backwards. The bumper must lead the segment into the cut. • DO NOT insert a diamond chainsaw into a slot narrower than the chain segments. Rapid pushback might occur. Reference: Most diamond segments are .225 inches (5.72 mm) wide.
Never use equipment that is not functioning properly. Have the saw repaired by qualified service personnel. • Turn engine OFF before refueling. Keep away from open flame. Always provide adequate ventilation when handling fuel. Move diamond chainsaw at least 10 feet (3 m) away from refueling area before starting. • SealPro diamond chains require a minimum water pressure of 20 psi (1.4 bar).
IMPORTANT product or property damage. Note: The diamond chainsaw is equipped with a two-stroke engine and must always be run using a mixture of gasoline and ICS measure the amount of oil to be mixed to ensure that correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture.

Place the diamond saw on clear ground. Ensure that secure IMPORTANT footing is established and chain is not contacting any objects.
