• When cutting rebar, slowly rock the saw so that you’re always cutting concrete as well as steel. This will help keep the diamonds exposed. Also, expect less diamond chain life when cutting rebar. • Expect more diamond chain stretch and guide bar wear when making “nose buried” cuts for extended periods of time, as the diamond chain does not have a chance to throw the slurry away from the nose of the guide bar. • If the saw begins to cut consistently crooked, turn the guide bar over and use the other side. Dress worn rails with belt sander. Note: The normal life of a guide bar is two to three diamond chains. Rebar can shorten guide bar life. • When using a new diamond chain, you can increase the cutting speed by opening up the diamonds by making a few cuts in an abrasive material such as a cinder block. MAINTENANCE SYSTEM CLEAN-UP • After cutting, run the 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 saw assembly. • Avoid getting any water in the carburetor or exhaust system. If water enters exhaust port, point the guide bar tip down and pull the starter handle several times to expel water from muffler. • Remove guide bar and diamond chain. Flush out the chain tensioner with high water pressure and lube with grease. • After cleaning the saw, spray the entire saw body, diamond chain, guide bar, and drive sprocket with lightweight oil. Using lightweight oil on the saw will minimize rust and help reduce slurry build up. TITLE MAINTENANCE DRIVE SPROCKET REMOVAL • STEP 1 – Prevent the sprocket from rotating by inserting the scrench or screwdriver through the holes in the sprocket and the hole in the saw body. • STEP 2 – Loosen the Trantorque® using a 7/8 in box end wrench. NOTE: Slurry will accumulate inside the Trantorque® adaptor while cutting. This can fill expansion spaces and make it difficult to remove. To faciliate removal, turn the hex nut counterclockwise approximately 1/8 turn, and then turn it clockwise slightly, so the hexnut is loose. Then lightly tap the end of the ring inside the hex nut several times with your box wrench. (This will loosen the slurry and allow the components to slide for removal). Continue to turn the hex nut counterclockwise to free the sprocket and Trantorque®. DRIVE SPROCKET INSTALLATION • STEP 1 – Clean the drive shaft and Trantorque® surfaces well before installation (Isopropyl alcohol is reccommended, to remove grease or hydraulic fluid). Note: Do not lubricate Trantorque® or shaft as slippage may occur. • STEP 2 – Slide the Trantorque® shaft adaptor onto drive shaft until it bottoms on the shaft. Note: Do not lubricate Trantorque® or shaft as slippage may occur. • STEP 3 – Slide drive sprocket onto the Trantorque® until it hits the bottom of the shaft. • STEP 4 – While holding the sprocket and Trantorque® as close to the frame of the saw as possible, finger tighten Trantorque® shaft adaptor. • STEP 5 – Stop the sprocket from rotating by inserting a scrench or screwdriver through the holes in the sprocket and the hole in the saw body. • STEP 6 – Tighten the Trantorque® shaft adapter with a torque wrench and a 7/8 in socket to 200 in-lbs (22.6 Nm). When a torque wrench is not available, use a 7/8 in box end wrench and tighten one-half turn past finger tight. Note: Do not turn around or reverse the direction of the drive sprocket to extend sprocket tooth life. Damage to chain or drive links may occur. TROUBLESHOOTING TROUBLESHOOTING • SLOW DIAMOND CHAIN SPEED – Be sure the powerpack is providing the correct hydraulic pressure and flow depending on your saw model (8 gpm / 30 lpm or 12 gpm / 45 lpm at 2,500 psi / 172.5 bar). • POOR CUTTING SPEED – The diamonds may be glazed over. Make a few cuts in an abrasive material such as a cinder block to expose the diamonds. • PREMATURE CHAIN STRETCH – Not enough water pressure. The minimum water pressure is 20 psi (1.5 bar). Insufficient water supply will result in excessive wear on the chain, which can lead to loss of strength and chain breakage. • CHAIN TENSIONER BREAKAGE – Side cover nuts are not tight enough. Torque to 20 ft-lbs (27 Nm). • WATER NOT FLOWING – Water hose is kinked or supply is not turned on. • MOTOR WON'T TURN – Hydraulics are hooked up backwards or powerpack is set on reverse flow.

An in-ft is defined as: depth in inches times length in feet. Note: 129 in-ft = 1 m2 Example: How many in-ft are in this doorway? 1. Determine the depth of the cut in inches. For this example, 8 inches. 2. Determine the length of the cut in feet. 3+7+3+7=20 feet 3. Multip...
