SAFETY RULES Woodworking can be dangerous if safe and proper operating procedures are not followed. As with all machinery, there are certain hazards involved with the operation of the product. Using the machine with respect and caution will considerably lessen the possibility of personal injury. However, if normal safety precautions are overlooked or ignored, personal injury to the operator may result.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles. SAVE THESE INSTRUCTIONS ADDITIONAL SAFETY RULES FOR BAND SAWS 1. DO NOT OPERATE YOUR BAND SAW UNTIL it is completely assembled and installed according to the instructions. 17.

If an adjustment is necessary, proceed as follows: A D E 1. DISCONNECT MACHINE FROM THE POWER SOURCE. 2.
CUTTING CURVES When cutting curves, turn the stock carefully so that the blade follows without twisting. If a curve is so abrupt that it is necessary to repeatedly back up and cut a new kerf, a narrower blade, a blade with more set, or additional relief cuts Fig. 44, may be necessary to allow the blade to cut more efficiently. The more set a blade has, the easier it will allow the stock to be turned, but the cut is usually rougher than where a medium amount of set is used. Fig.
Fig. 46 Fig. 46 illustrates a typical bevel cutting operation using a miter gage. Fig. 47 Fig. 47 illustrates a typical resawing application using the accessory rip fence.

BAND SAW BLADES A band saw blade is a delicate piece of steel that is subjected to tremendous strain. You can obtain long use from a band saw blade if you give it fair treatment. Be sure you use blades of the proper thickness, width and temper for the various types of material to be cut. Always use the widest blade possible. Use the narrow blades only for sawing small, abrupt curves and for fine, delicate work. This will save blades and will produce better work.
