The miter cutting head is the unit that performs the cut, and is pivoted downward manually by means of the operating lever. The head is mounted to a cast iron base, and consists of a blade support unit with guard, transmission unit, and motor. The depth of cut is set by adjusting the depth stop.

7.1 Contents of shipping container 7.0 Unpacking 1 1 1 4 1 1 2 1 1 Open shipping container, and any secondary boxes. Check for shipping damage; report any damage immediately to your distributor and shipping agent. Do not discard any shipping material until the Cold Saw is assembled and running properly. Compare the contents of your container with the following parts list to make sure all parts are intact. Missing parts, if any, should be reported to your distributor.
8.1 Operating lever Refer to Figure 3. 1. Remove the hex nut and screw from the hole at the front of the saw head (Figure 4). These fasteners will not be used again unless the machine needs to be transported in the future. 2. Insert the operating lever into the threaded fill hole. Rotate it a good distance into the hole, and make sure the final orientation of the handle grip is in a comfortable position for the operator, as shown in Figure 3. 3.
the fuse holder or circuit breaker to prevent it being turned on while the machine is being wired. See table 2 for recommended circuit sizes for your particular model. NOTE: Local codes take precedence over recommendations. CS-275 Recommended circuit size (3PH 230V) 10A CS-275-1 (1PH,115/230V) 20A CS-315 (3PH 230V) CS-315-1 (1PH, 230V) 15A 20A Table 2 9.1 Three-phase models Figure 6 The CS-275 (3-phase) and CS-315 (3-phase) are rated for 230-volt only power. They are not supplied with a plug.
4. Switch the leads in the coolant pump junction box, according to the diagram in Figure 9. (A diagram is also included on the coolant pump.) 10.2 Vise Refer to Figure 10. The vise is self-centering and has a cam action lever for fast clamping. Use the handwheel to move the vise jaw about 1/16-inch away from the work piece, then rotate the cam lever to tighten. The adjustable anti-burr arm keeps the off-cut end from flexing, which can cause burring. Use a 10mm hex key to loosen the arm for adjusting.
10.4 Blade replacement Disconnect machine from the power source before changing saw blades. Failure to comply may result in serious injury! To change the saw blade (Figure 12): 1. Disconnect machine from power. 2. Clamp a piece of wood in the vise, and lower the blade upon it to prevent rotation. 3. Release the linkage from the blade guard at (A) with a 5mm hex key, and rotate the guard out of the way. 4. Remove the screw (B) with a 10mm hex key. NOTE: Left-hand threads; turn clock-wise to loosen.
7. Pull the operating lever to bring down the blade into the work piece. You will manually control the speed of the downstroke. 8. When the cut is complete, release the trigger and raise the head. The spring will help return the head to upward position. 9. Release the vise using the handwheel, and remove the work piece. 13.4 Lubrication For long life and trouble free operation, it is essential that this machine is kept well lubricated. The vise and leadscrew should be oiled daily.
speed depends on the cross-section of the material. Solid or thick-walled materials (thickness>5mm) can therefore be cut at high speed providing there is sufficient swarf removal by the blade, while thin-walled materials such as tubes or thin profiles must be cut with a low feeding speed. 14.2 Determining proper tooth pitch Proper tooth pitch depends on: a) the size of the section; b) the hardness of the material; c) wall thickness.
14.7 Teeth shape “C” TYPE SHARPENING (HZ) Coarse toothing with roughing tooth raked on both sides and non-raked finishing tooth. The roughing tooth is about 0.3 mm higher. Coarse toothing with roughing tooth and finishing tooth. Used in saws with pitch greater than or equal to 5 mm for cutting ferrous and non-ferrous materials with solid or solid-profiled sections.
15.0 Troubleshooting 15.1 Blade and cutting problems Problem Probable Cause Solution Ensure proper coolant flow; hoses unclogged; nozzles pointed correctly, etc. Make sure coolant type is suitable for the machine. Coolant flow problem Check the blade speed and the type of blade you are using. Also be aware of feed pressure. With a new blade it is necessary to start cutting at half feeding speed.
15.2 Machine fault and operating problems Problem Green pilot lamp not lit when ON button pressed Probable Cause Solution No incoming power Lamp fuse or bulb is out Check connections at machine and power source. Replace fuse/bulb. Emergency Stop engaged Rotate Emergency Stop button to disengage. Check: the phases; the cables; the plug; the socket. Also check that the motor connections are in place.
