IMPORTANT product or property damage. Note: The chain-based cut off saw 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.

The diamond chain should be tight but be able to be pulled around the guide bar by hand. Note 3: To prevent chain tensioner breakage, be sure the side cover nuts are tightened to approximately 20 ft-lbs (27Nm). 613GC OPERATOR’S MANUAL SET-UP STEP 8 Hold the guide bar nose up and tension the chain.
Do not mix more than one month’s supply of fuel. This helps prevent the separation of the two stroke oil from the gasoline (varnishing). • If the cut-off saw is not used for an extended period of time (3 months) the fuel tank should be emptied and cleaned. FUELING •...

= 12”x12”x12” = 150 lbs. (30cm x 30cm x 30cm = 68kg). • Check for live electrical wiring near the cutting area or in the concrete to avoid electrocution. 613GC OPERATOR’S MANUAL OPERATION ® require a minimum water pressure of 20 psi (1.4 bar).
As the cut-off saw begins to rotate up, feed force is developed down the line of the intended cut. Once the cut-off saw is fully rotated upwards, pull the cut-off saw out of the cut a few inches and re- engage the pick into the cut and repeat.
SYSTEM CLEAN-UP • After cutting, run the cut-off saw for at least 15 seconds with the water on to flush slurry and debris from diamond chain, guide bar and drive sprocket. • Wash concrete slurry from cut-off saw assembly. •...

Periodically clean the water ports inside the groove of the guide bar using a small diameter piece of wire. • The guide bar is solely a guide track for the diamond chain. Never use the guide bar to lift, twist or pry concrete material. 613GC OPERATOR’S MANUAL MAINTENANCE...
• CUT-OFF SAW WON’T REACH FULL RPM - Air filter or pre filter may be dirty. • SLOW DIAMOND CHAIN SPEED – Diamond chain tension too tight. Diamond chain should always be able to be pulled around the guide bar by hand. It is normal for the diamond chain drive links to hang below the guide bar.
For this example, 8 inches. 2. Determine the length of the cut in feet. 3+7+3+7=20 feet 3. Multiply the two numbers 8 in x 20 ft = 160 in-ft 613GC OPERATOR’S MANUAL REFERENCE Cutting Rate 15-25 sq-in/min (90-160 sq-cm/min) 20-30 sq-in/min (160-190 sq-cm/min)
