SECTION 1: SAFETY For Your Own Safety, Read Instruction Manual Before Operating This Machine The purpose of safety symbols is to attract your attention to possible hazardous conditions. This manual uses a series of symbols and signal words intended to convey the level of importance of the safety messages. The progression of symbols is described below. Remember that safety messages by themselves do not eliminate danger and are not a substitute for proper accident prevention measures.
WEARING PROPER APPAREL. Do not wear clothing, apparel or jewelry that can become entangled in moving parts. Always tie back or cover long hair. Wear non-slip footwear to reduce risk of slipping and losing control or accidentally contacting cutting tool or moving parts. HAZARDOUS DUST. Dust created by machinery operations may cause cancer, birth defects, or long-term respiratory damage. Be aware of dust hazards associated with each workpiece material.
Additional Safety for Metal Bandsaws Serious injury or death can occur from getting fingers, hair, or clothing entangled in rotating or moving parts or making direct contact with the moving blade. To minimize risk of injury, anyone operating this machine MUST completely heed hazards and warnings below. BLADE CONDITION. Do not operate with dull, cracked, or badly worn blade. Inspect blades for cracks and missing teeth before each use. HAND PLACEMENT.
SECTION 2: POWER SUPPLY Availability Before installing the machine, consider the availability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed. To minimize the risk of electrocution, fire, or equipment damage, installation work and electrical wiring must be done by an electrician or qualified service personnel in accordance with all applicable codes and standards.
Grounding & Plug Requirements This machine MUST be grounded. In the event of certain malfunctions or breakdowns, grounding reduces the risk of electric shock by providing a path of least resistance for electric current. This machine is equipped with a power cord that has an equipment-grounding wire and a grounding plug. Only insert plug into a matching receptacle (outlet) that is properly installed and grounded in accordance with all local codes and ordinances.
SECTION 3: SETUP Unpacking Inventory This machine was carefully packaged for safe transport. When unpacking, separate all enclosed items from packaging materials and inspect them for shipping damage. If items are damaged, please call us immediately at (570) 546-9663. The following is a list of items shipped with your machine. Before beginning setup, lay these items out and inventory them.
Cleanup The unpainted surfaces of your machine are coated with a heavy-duty rust preventative that prevents corrosion during shipment and storage. This rust preventative works extremely well, but it will take a little time to clean. Be patient and do a thorough job cleaning your machine. The time you spend doing this now will give you a better appreciation for the proper care of your machine's unpainted surfaces.
Bench Mounting Assembly Number of Mounting Holes............................. 3 Diameter of Mounting Hardware Needed... 1 ⁄4" The machine must be fully assembled before it can be operated. Before beginning the assembly process, refer to Needed for Setup and gather all listed items. To ensure the assembly process goes smoothly, first clean any parts that are covered or coated in heavy-duty rust preventative (if applicable).
4. Install (1) base foot onto each base corner (see Figure 10). Serious injury or death can result from using this machine BEFORE understanding its controls and related safety information. DO NOT operate, or allow others to operate, machine until the information is understood. DO NOT start machine until all preceding setup instructions have been performed.
SECTION 4: OPERATIONS Operation Overview The purpose of this overview is to provide the novice machine operator with a basic understanding of how the machine is used during operation, so the machine controls/components discussed later in this manual are easier to understand. Due to the generic nature of this overview, it is not intended to be an instructional guide.
Blade Selection Selecting the right blade for the cut requires a knowledge of various blade characteristics. Blade Terminology Model Blade Width G0885............................................................... 1⁄ 2" C Tooth Type The most common tooth types are described as follows, and illustrated in Figure 12. H F G Model Blade Length G0885...........................................................561⁄ 2" Measured from the back of the blade to the tip of the blade tooth (the widest point).
Blade Pitch (TPI) The chart below is a basic starting point for choosing teeth per inch (TPI) for variable pitch blades and standard raker set bi-metal blades/ HSS blades. However, for exact specifications of bandsaw blades that are correct for your operation, contact the blade manufacturer. 3. Refer to "Material Shapes" row and find shape of material to be cut. 4. In applicable row, read across to right and find box where row and column intersect.
Changing Blade All saw blades are dangerous and may cause personal injury. To reduce the risk of being injured, wear leather gloves when handling and uncoiling saw blades. Blade Tension Knob Blade Guide Bearings Figure 15. Headstock opened for blade removal. 8. Items Needed Qty Leather Gloves............................................1 Pair Note: It is sometimes possible to flip the blade inside out, in which case the blade will be installed in the wrong direction.
Blade Breakage 10. Complete blade change using the Tensioning Blade procedure below. 11. Re-install wheel cover. 12. Reposition blade guard and left blade guide bearing assembly. Tensioning Blade Proper blade tension is essential to avoid blade vibration, twist, or slippage on the wheels. A correctly tensioned blade provides long blade life, straight cuts, and efficient cutting times. Many conditions may cause a bandsaw blade to break.
Blade Care & Break-In Blade Care To prolong blade life, always use a blade with the proper width, set, type, and pitch for each application. Maintain the appropriate feed rate, feed pressure, and blade speed, and pay attention to the chip characteristics (Refer to Blade Speed Chart on Page 21 and Chip Inspection Chart on Page 22). Keep your blades clean, since dirty or gummed up blades pass through the cutting material with much more resistance than clean blades, causing unnecessary heat.
Blade Speed Chart The chart in Figure 20 offers blade speed guidelines for various metals, given in feet per minute (FPM) and meters per minute (M/Min). Choose the closest available speed on the machine, then adjust the feed rate as necessary, using the appearance of the chips produced as a guide. Refer to the Chip Inspection Chart that follows for recommendations on adjusting feed rate or blade speed based on the appearance of the chips produced.
Chip Inspection Chart The best method for choosing the cutting speed and feed rate for a cutting operation is to inspect the chips created by the cut. These chips are indicators of what is commonly referred to as the "chip load." Refer to thin &below curled to evaluate chip characteristics and determine whether to adjust feed rate/ the chip inspection chart thinor & curled pressure, blade speed, both.
Feed Rate The speed at which the saw blade will cut through a workpiece is controlled by the blade type and feed rate. The feed rate is controlled by how hard the user pulls the saw down into the material. The feed rate should be proportional to the speed of the saw. Allow the blade to remove chips as it cuts through the material. Here are some signs that the feed rate is too fast. • Saw binding in cut and motor slows down. • Saw blade flexing as it moves through cut.
NOT RECOMMENDED Operation Tips RECOMMENDED The following tips will help you safely and effectively operate your bandsaw and get the maximum life out of your saw blades. Tips for cutting: Figure 24. Example of work holding options by material shape. Headstock Angle Before adjusting headstock, verify workpiece is held firmly in place by the vise. The headstock can be adjusted to cut any angle, from a straight 90-degree cut-off to a 60-degree angle, by loosening the angle lock handle.
