WARNING

could result in death or serious injury.

Diamond chain breakage can result in high-speed ejection of parts, which can result in death or serious personal injury to operators or bystanders. The items listed below are critical to minimizing the risk of diamond chain breakage and injury.

• DO NOT operate the concrete chain saw with a damaged, modified, broken, or missing

side cover, bottom guard, or guard flap. The side cover, bottom guard, and guard flap provide protection against contact with moving parts, ejected debris, broken diamond chain, thrown water and concrete slurry.

• DO NOT operate the saw with loose, missing, damaged or improperly repaired parts.

• DO NOT insert the saw into a slot narrower than the diamond chain segments. Rapid

pushback might occur. Reference: Most diamond segments are .225 in (5.72 mm) wide.

• DO NOT use damaged, modified or improperly repaired diamond chain.

• DO NOT run the saw upside-down. Concrete debris can fly back into the operator’s face.

• DO NOT cut ductile iron pipe with the saw. Segment loss or diamond chain breakage may

occur.

660GC OPERATOR’S MANUAL

THE FOLLOWING SYMBOL APPLIES TO ALL ITEMS LISTED ON THIS PAGE

CAUTION

A potentially hazardous situation exists which, if not avoided, may result in minor or moderate injury or property damage.

• Always turn the saw OFF when performing maintenance on the saw including diamond

chain tensioning.

• 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 the saw at least 10 feet (3 m) away from refueling area before starting.

• Diamond chains require a minimum water pressure of 20 psi (1.5 bar). Insufficient water

supply may result in excessive wear to the diamond chain, which can lead to loss of strength and diamond chain breakage, and/or damage to the guidebar nose sprocket.

• Never start the saw unless the guidebar, diamond chain and side cover are properly

installed.

GENERAL SAFETY PRECAUTIONS

• Always wear protective clothing, including hard hat, eye protection, hearing protection, and gloves.

• Avoid loose fitting clothing.

• Perform safety checks before starting each day.

• Always operate tool with solid footing and with both hands on saw.

• Remove or control slurry to prevent slippery conditions while cutting.

• Be sure there are no obstructions (plumbing, electrical conduit, air ducts) and no unnecessary people present.

• Set up a well-marked safety zone with a roped boundary and clear signs.

• Provide adequate ventilation when working in an enclosed area. Breathing exhaust gases is dangerous.

• To avoid electrocution, check for live electrical wiring near cutting area.

product or property damage.

Note: The concrete chain saw is equipped with a two-stroke engine and must always be run

A potential situation exists which, if not avoided, may result in

using a mixture of premium gasoline and ICS

®

two-stroke engine oil, or other high quality 2-stroke oil that has been formulated for air cooled power equipment. It is important to accurately 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.

• This engine is designed to be operated on premium unleaded gasoline.

• Use high quality, unleaded gasoline with a minimum octane rating of 90. If lower octane

gasoline is used, engine temperature will increase which will result in a piston seizure and damage to the engine.

• Fuel mixture: 25:1 (4%) gasoline/oil mixture. Incorrect fuel mixture is the number one

cause of piston seizure.

®

• Use ICS

brand two-stroke engine oil, or other high quality 2-stroke oil that has been

formulated for air cooled power equipment.

• Never use two-stroke oil formulated for water-cooled two-cycle engines, such as

outboard motor oil.

• Never use motor oil intended for four-stroke engines.

• Use of water is required to cool bar and chain during break-in period.

ENGINE BREAK-IN

• It is very important to break-in a new engine to “seat” all moving parts, especially the

piston rings.

• To break-in the engine, run one full tank of 25:1 (4%) fuel at idle, cycling the throttle every

5 to 10 minutes to prevent loading.

• Failure to break-in an engine may result in piston seizure.

• Failure to break-in an engine at altitude will result in up to 50% loss of power output for

the first hour of operation making the initial cutting experience unsatisfactory.

• Proper chain tension, especially for first cut, is extremely important. Over-tensioning of

bar and chain, especially at altitude, could result in severe loss of power output making initial cutting experience unsatisfactory.
