-Examine blade flanges for damage, excessive wear and cleanliness before mounting blade. Blade should fit snugly on the sha and against the inside/outside blade flanges. -Ensure that the blade is marked with an operating speed greater than the blade sha speed of the saw.
-ALWAYS allow the machine a proper amount of time to cool before servicing. -Keep the machinery in running condition. -Fix damage to the machine immediately and always replace broken parts. -Dispose of hazardous waste properly. Examples of potentially hazardous waste are used motor oil, fuel and fuel filters.

2.2 Operating Principle The following instructions were compiled to provide you information on how to obtain long and trouble free use of the machine. Periodic maintenance of the machine is essen- tial. Read the manual carefully and thoroughly familiarize yourself with the machine and all it’s functions.
-Water tank level. -Oil level in the engine. -Air filter maintenance indicator. -Check arbors and flanges are clean and undamaged. -If operating in wet-cutting, check water jets for adequate flow. -Align pointer with saw blade. NOTICE: The warranties are VOID if the machine is run without oil. 2.6 To Start Before starting the machine, operator must know the location and function of all con- trols.
2.6.2 To Start - Petrol Engine 1. Open the fuel tap by moving the fuel ON/OFF lever fully to the right. 2. If starting the engine from cold, set the choke ON by moving the choke lever fully to the le . If restarting a warm engine, the choke is usually not required.
4. Lower blade into cut slowly. 5. Cut as fast as blade will allow. If blade misaligns from cut, reduce forward speed or depth of cut. 6. Use only enough side pressure on saw handles to follow cutting line. 2.9 Cutting Lower the blade into concrete to the required depth by turning the tilt crank counter- clockwise.
6. To check alignment, use a steel straight edge. See Figure 1. 7. Line up the straight edge along the outside face of both pulleys shown in the drawing. All pulleys have (2) set screws in the bottom of their grooves. Set screws require thread locking lock title.
2.13 Li ing 1. NEVER tow the machine. 2. ONLY use steel ropes or chains for li ing. 3. Make sure that the ropes or chains have enough li ing capacity to hold the machine (see the information on the machine plate for weight). 4.
3.2 Lubrication The long life and successful operation of any machinery is dependent on frequent and thorough lubrication. Before using the machine, always check the oil and use proper oil with the correct type and grade as recommended. NOTICE: DO NOT mix types of engine oil and DO NOT overfill the oil. Damage to the ma- chine may occur if oils are mixed or overfilled.
3.6 Troubleshooting POSSIBLE CAUSES SOLUTION SYMPTOM Flush water system. Check flow to both (Wet cutting) Insu icient water (Usually Uneven segment sides of blade. Replace bad bearings, on one side of blade) Equipment defects wear worn arbor sha or misalignment to also can cause the segments to wear spindle.

POSSIBLE CAUSES SOLUTION SYMPTOM Tighten the blade sha nut. Make sure Blade flutters in cut as a result of losing Cracks in core blade is running at proper speed and blade tension. that drive pin is functioning properly. Blade specification is too hard for the material being cut.
Page 18
POSSIBLE CAUSES SOLUTION SYMPTOM Undercutting the core Abrasive wearing of the core faster Use water to flush out fines generated during cutting. than the segments. Use wear-retardant cores. Make certain the blade is mounted on the Collars/flanges are not properly tightened, Arbor hole out of round proper sha diameter.
