CHOOSING & INSTALLING A SAW BLADE Blade Selection Blade selection is dependent on the type and thickness of the material being cut, but is also a matter of experience and personal preference. There are numerous types of blades available on the market specifically suited for various cutting applications such as metal-cutting and spiral blades which cut in all directions. Try test-cutting with a sample of each to determine which blade works best for you with different materials.
Installing or changing blades Fig. 1 Always turn off and unplug the machine before removing, handling or changing blades. Remove an installed, worn or broken blade by loosening the thumbscrews and on the upper and lower blade mounts until the blade can be removed. (See Fig. 1, 2) 1. To install a blade, push the blade tension lever towards the rear of the saw. (See Fig. 3) 2. With the blade teeth facing forward, slip one end of the blade through the hole in the table . (See Fig. 2) 3.
Blade speed selection is subjective and is dependant on a variety of factors: type and thickness of material being cut, type of blade being used, feed rate, required finish quality as well as experience, personal preference and comfort level of the user. There are no hard and fast rules. Be patient – practice and experience will be your best teacher.
1. With the saw turned off and unplugged, install the appropriate blade for the type of material to be cut and the type of cut to be made (Refer to the section “Choosing and Installing a Saw Blade” on page 9). 2. Adjust the workpiece hold-down and the blower nozzle to your liking. 3. Turn on the saw and set the speed controller to the desired blade speed. 4.
3. Release tension on the blade by pushing the blade tension lever towards the rear of the saw. 4. Loosen the thumbscrew on the lower blade mount, located under the table, to release the blade from the mount. 5. Raise the upper arm assembly which will lift the blade up through the hole and above the table. 6. Position the workpiece on the table so that the guide hole lines up with the hole in the table. 7.
MAINTENANCE, ADJUSTMENTS AND SERVICING Handling Never lift the saw by the upper arm assembly as this will result in damage to the drivetrain. Rather lift the saw by the front of the table and by the motor. Maintenance • Always release tension on the blade when the saw is not in use. • Clean the saw regularly with a soft bristle brush or by vacuuming to keep cutting dust from accumulating. • An occasional application of a light dab of grease on the front and rear trunnions (See Fig.
