853PRO OPERATOR’S MANUAL SAFETY THE FOLLOWING SYMBOL APPLIES TO ALL THE ITEMS LISTED ON THIS PAGE WARNING A potentially hazardous situation exists which, if not avoided, 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.
SAFETY 853PRO 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. • Diamond chains require a minimum water pressure of 20 psi (1.

Set-UP 853PRO OPERATOR’S MANUAL GUIDE BAR AND DIAMOND CHAIN INSTALLATION STEP 1 Loosen the side cover nuts and remove the side cover. STEP 4 Mount the chain on the bar starting at the drive sprocket & continue over the bar nose. Install the chain correctly. The bumper must always lead the segment into the cut as shown here. STEP 2 Place the bar onto the studs and the chain adjustment pin. STEP 3 Turn the chain-tensioning screw CCW until the bar comes into contact with the drive sprocket.
53PRO OPERATOR’S MANUAL Set-UP GUIDE BAR AND DIAMOND CHAIN INSTALLATION STEP 6 Install the bar clamp plate over the bar studs. STEP 8 Tension the chain. Do not over tension the diamond chain. Loss of power will result. It is normal for the drivelinks to hang underneath the guide bar. The diamond chain should be snug but be able to be pulled around the guide bar by hand. STEP 7 Install the side cover over the bar studs and install side cover nuts. Finger tighten only.
OPERATION 853PRO OPERATOR’S MANUAL PRE-CUT CHECKLIST • Proper Diamond Chain Tension: The diamond chain should be tight but easily pulled around the guide bar by hand. • Ensure all safety devices are properly mounted and functional and that all controls are in proper working order. • Be sure there are no obstructions (plumbing, electrical conduit, air ducts).
853PRO OPERATOR’S MANUAL OPERATION CUTTING TIPS • To start a cut, hold trigger on full throttle and slowly plunge the nose of the guide bar straight into the wall. Use the fixed WallWalker ® as a pivot point and pull up on the rear handle to rotate the guide bar into the cut. • Always operate the saw at full throttle. Apply enough feed force so that the free running RPM drops 20 to 30%. If too much force is applied, the saw will lug or stall.
MAINTENANCE 853PRO OPERATOR’S MANUAL 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.
853PRO OPERATOR’S MANUAL MAINTENANCE TITLE 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.
TROUBLESHOOTING 853PRO OPERATOR’S MANUAL 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).
853PRO OPERATOR’S MANUAL REFERENCE APPROXIMATE CUTTING RATES Material Cutting Rate Concrete – 6 in (15 cm) 5 lineal in/min (12 cm/min) Red Brick – 6 in (15 cm) 10 lineal in/min (25 cm/min) Rebar – #4 (12 mm) 10–20 seconds through each piece INCH-FOOT DEFINITION An in-ft is a measure of how much material is to be cut. 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.
