Safety rules It’s essential to power on your bandsaw machine for at least one hour every two years, if you seldomly use the machine. (This period of power-on must be without proceeding with other operation) Otherwise the machine program may disappear due to not strictly follow this safety rule.
Page 6
Safety rules Never cut carbon or any other material that may produce and disperse explosive dust. It is possible that sparks from motors and other machine parts will ignite and explode the air-borne dust. Never adjust the wire brush or remove chips while the saw blade is still running.
Safety is a combination of a well-designed machine, operator’s knowledge about the machine and alertness at all times. COSEN’s band machine has incorporated many safety measures during the design process and used protective devices to prevent personal injuries and potential risks. Warning labels also serve as a reminder to the operator.

BEFORE OPERATING Choosing an appropriate saw blade and using the right cutting method is essential to your cutting efficiency and safety. Select a suitable saw blade and cutting method based on your work material and job requirements e.g. cutting accuracy, cutting speed, economic concern, and safety control. Wet cutting If you choose dry cutting or low-speed cutting, the chips may accumulate in machine parts and may cause operation failure or insulation malfunction.
CONTROL PANEL The control panel is located on the top of the electrical box. It includes the following function: power system, hydraulic system, cooling system, the human-machine–interface (HMI) and the projecting light system.

BREAKING-IN THE BLADE When a new saw blade is used, be sure to first break in the blade before using it for actual, extended operation. Failure to break in the blade will result in less than optimum efficiency. To perform this break-in operation, the following instructions should be followed: Step 1 - Reduce the blade speed to one-half of its normal setting.

INTRODUCTION TPI: The number of teeth per inch as measured from gullet to gullet. 2. Tooth Rake Angle: The angle of the tooth face measured with respect to a line perpendicular to the cutting direction of the saw. 3.Tooth Pitch: Tooth pitch refers to the number of teeth per inch (tpi). 1 inch equates to 25.4 mm. A distinction is made between constant tooth pitches with a uniform tooth distance, 2 tpi for example, and variable tooth pitches with different tooth distances within one toothing interval.
Page 71
4. Tooth pitch The main factor here is the contact length of the blade in the workpiece. If it is 4P, 25.4 ÷ 4 P = 6.35 mm, that is, one tooth is 6.35 mm. If it is 3P, 25.4 ÷ 3 P = 8.46 mm If the number is small, it means that the tooth is large. What is written as 3/4 is that it is a variable pitch of large (3) / small (4).

The following diagrams suggest some costeffective ways of loading and fixturing. Be sure, regardless of the arrangement selected, that the work can be firmly secured to avoid damage to the machine or injury to the operator.
