ORIGINAL INSTRUCTIONS For your personal safety, READ and UNDERSTAND before using. SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE. Warning: On tools equipped with over load protection, when motor has been cut off due to over load, always switch on machine with no load for at least 3 minutes to reduce temperature before returning to operation to avoid burn out of the motor.

GENERAL SAFETY INSTRUCTIONS WARNING Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference. The term "power tool" in the warnings refers to your mains-operated (corded) power tool. 1) WORK AREA SAFETY Keep work area clean and well lit.

will reduce personal injuries. Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents. Remove any adjusting key or wrench before turning the power tool on.

saw for operations different than intended could result in a hazardous situation. CAUSES AND OPERATOR PREVENTION OF KICKBACK Kickback may occur when the nose or tip of the guide bar touches an object, or when the workpiece closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a sudden reverse reaction, kicking the guide bar up and back towards the operator.
SAFETY DEVICES Hand Guard: Protects the hand from debris and helps to block a broken chain. Never operate without the hand guard in place. Replace if damaged. Splash Flap: Protects from thrown debris and slurry. Never operate without the splash flap in place. Replace if damaged.
TENSIONING THE CHAIN Note: Proper chain tension with a concrete chain saw is much looser than with a wood chain saw. It must be loose enough to run freely with only water as its lubrication. • An over tensioned chain will give unnecessary load to the motor and will lead to premature chain stretch, sprocket damage, and spindle bearing damage.
WATER SUPPLY This tool must always be used with a supply of clean water at a minimum pressure of at least 1.5bar (20 psi). The water serves as a coolant to avoid the working surface of the diamond segments from overheating and since it is not possible to use oil, the water also serves as the only lubricant available for the chain and guide bar.

SHARPENING A NEW OR GLAZED CHAIN If the chain is new, or if the chain’s diamond segments become glazed, sharpen by making a few cuts into an appropriate alumina oxide or silicon carbide dressing stone. Simply make shallow plunge cuts into the stone as many times as necessary to restore its cutting performance.
Overheat Thermal Protection If the temperature of the motor gets too high, the thermal protection will shut the motor down. The switch must be first shut off and then restarted. When this happens, do not immediately start cutting after restarting the motor.
NOTE: The cutting technique for concrete is very different from a wood cutting chain saw, where cutting with the nose of the guide bar must be avoided. With a wood cutting chain saw, the hook-shaped saw teeth can easily grab the wood fibers, leading to a kickback hazard. Diamond segments which are cutting concrete do not behave in the same way.
Drive Sprocket Running a good chain on a worn out sprocket will prematurely wear out its drive links. After about 3 chains, the drive sprocket will wear away and need replacement. CHANGING THE DRIVE SPROCKET To change the drive sprocket, first remove the side cover, chain, and guide bar. Using circlip pliers, remove the circlip, then the washer which retain the drive sprocket, then lift the sprocket off the splines.
