  • Page 11 has vertical adjustment. The upper guides are adjustable so that the guides are held just above the job being cut. This gives the blade the maximum amount of stability and also keeps the amount of blade that is exposed to a minimum. If you are using blades narrower than 1/4", there is available an optional cool block guide system.

  • Page 12: Where To Locate Your Machine

    Identification There is a plate at the back of the machine listing all the manufacturing data, including the serial number, model, blade length, etc. Tension scale Tension scales are designed to indicate the compression of a spring. As a rule, the greater the spring compression, the greater the tension on the blade.

  • Page 13: Unpacking Your Machine

    Unpacking your machine. To unpack your machine, you will need tin snips, knife and a wrench. 1. Using the tin snips, cut the banding that is securing the machine to the pallet. WARNING: EXTREME CAUTION MUST BE USED BECAUSE THE BANDING WILL SPRING AND COULD CAUSE INJURY.

  • Page 14: Assembly And Setup

    If no lifting device is available, the machine can be removed from the pallet as follows: Note: The machine is heavy, and if you have any doubt about the described procedure, seek professional assistance. Do not attempt any procedure that you feel is unsafe or that you do not have the physical capability of achieving.
  • Page 15 2. Assemble the motor to the back of the bandsaw after the drive belt has been attached to the motor pulley and is located in the drive groove in the fly wheel. Belt tensioning bolt Motor with mounting flange fitted 3.
  • Page 16 Mobility Kit (optional) If you have purchased a mobility kit or it is supplied standard with your machine, now is the ideal time to fit it, as the table has not been fitted to the machine, and the bandsaw is lighter; however, the mobility kit can be fitted later if you require it.
  • Page 17 leveling bolts at all four corners of the machine. 1. Raise the machine off the ground onto wooden blocks. 2. Fit a bolt as shown to either two or four corners of the machine, depending on if you fit the mobility kit. 3.
  • Page 18 1. Remove the trunion clamp handle from the relevant bolts. 2. Position the table on the clamp bolts, taking care not to damage any of the table or trunion surfaces. 3. While one person supports the table, the other person feeds the bolts through the trunion slots.
  • Page 19 Fence Steel block Fixing screw Fence in low position The bandsaw is supplied with an aluminum fence. Assemble the fence to the cast-iron bracket with the bolts and steel block provided. Adjustment and squaring of the fence will be covered later in the manual. Slide the Fence in high position bracket onto the round steel bar (attached to the table).
  • Page 20 Bottom blade guards Bottom blade guard It is very important to have the blade covered for safety. Guards are provided at the top of the lower door and just above the table dust port. The door guard must be moved vertically and clamped in position before operating the bandsaw.
  • Page 21 The switch is mounted on the main pillar of the bandsaw in the incorrect position for operation. This is for transport reasons, and the switch will have to be moved to the operation position prior to starting the machine. Remove the two screws, reposition the switch box and reassemble the screws.

  • Page 22: Adjusting The Bandsaw

    16. Use a push stick at the end of a cut. This is the most dangerous time because the cut is complete and the blade is exposed. Push sticks are commercially available. 17. Hold the wood firmly and feed it into the blade at a moderate speed. 18.
  • Page 23 2. Inspect the teeth and the general condition of the blade. If the Blade tracking teeth are pointing in the wrong direction when you hold the adjustment handle blade up to the machine, you will have to turn it inside out. To do this, hold the blade with both hands and rotate( see blade section of this manual).
  • Page 24 between the wheels. The bandsaw achieves this by tensioning the blade and thus stretching it. The next complication is that the blade heats up while cutting the wood and expands its length. This allows the blade to become slacker and lose its tension. To overcome this, the bandsaw has a compression spring that allows for the expansion and keeps a constant pressure on the blade.
  • Page 25 6. Teeth set insufficient. The set of the teeth is there to create a slot for the back of the blade to pass through. Ideally the body of the blade should not touch the side of the job, but this is not practical, and the best that we can hope for is that little pressure is caused on the blade.
  • Page 26 4. Slightly loosen the clamp screws and adjust the fence to compensate. 5. Repeat steps 2, 3 & 4 until the blade is centered. Note. You may have to do several fine adjustments, and it is better to do several small adjustments until you become skilled at the procedure.
  • Page 27 Refit all the guards and close the doors. Replace the table insert and check that the blade moves freely through the table insert. Check that all wrenches and loose parts are removed from the machine. Plug the machine into the power. Turn the machine on for a second and switch off. Watch how the blade runs.
  • Page 28 Laguna Guide system. 1. As with the roller guide systems, the Laguna Guide system will damage your blade if it is not adjusted correctly. The guide blocks must not come in contact with the teeth of the blade.
  • Page 29 5. The Laguna guide system can be used with 1/4" to 1 1/4" blades. 6. The Laguna guide system uses ceramic to support and guide the blade. This has many advantages, (very poor conductor of heat, very resistant to wear, etc.). The disadvantage is that it is very brittle, so the guides must never be dropped, exposed to hard knocks, hit with hard objects or used with badly welded blades.
  • Page 30 Top guide 1. Loosen the side guides. 2. Rotate the blade by hand and ensure that it is tracking consistently in the correct position. 5. Loosen the rear guide clamp screw and push the guide forward so that it just touches the back of the blade.

  • Page 31: Using The Bandsaw

    This can be overcome to a great degree by using the Resaw King blade from Laguna Tools. The blade has a lot of advantages such as superior surface finish to the cut, thin kerf (low wood wastage), ability to be re-sharpened, will cut hard woods and a long life.
  • Page 32 Changing the fence height 1. Loosen the two clamp screws that are located on the cast-iron bracket. 2. Slide the aluminum fence off the cast iron bracket. 3. Slide the aluminum fence back onto the bracket using the second slot and retighten the clamp screws. Resawing Clamp screws Resawing is the process of cutting a board in half along its height.
  • Page 33 smaller the set, the smaller the saw cut, and the larger the radius that can be cut, but the wood is wasted less. On tipped blades (Resaw King), there is no set, as the tip is wider than the backing material. Thickness The thicker the blade, the stiffer the blade, and the straighter the cut.
  • Page 34 Pitch that is Too Coarse The blade has a short cutting life. The teeth wear excessively. The bandsaw vibrates. Width The dimension from the back of the blade, to the front of the teeth. The wider the blade, the stiffer the blade and the straighter the cut. This is usually called beam strength. But wide blades cannot cut small radiuses.
  • Page 35 Every effort has been made to ensure that your blade arrives in perfect condition. When you receive your blade open the packaging and inspect the blade for damage. If the blade is damaged do not use it but contact Laguna Tools within 24 hours. Using a damaged blade is dangerous.
  • Page 36 2. Untwist the blade insuring that the teeth do not catch on clothing or cause injury. 1. Lightly place your foot on the bottom of the blade [one coil only]. It is recommended that the blade is placed on material that will not damage the blade teeth [wood or cardboard].
  • Page 37 Teeth direction. Blade uncoiled If the teeth are not facing the correct direction [facing up when fitted to the bandsaw], Rotate the blade as below. 1. Lightly place your foot on the bottom of the blade. It is recommended that the blade is placed on material that will not damage the blade teeth [wood or cardboard].
  • Page 38 Coiling the blade. Hand position Blade coiling Blade coiling Blade coiling Blade coiled If you need to coil the blade, coil as follows. 1. Lightly place your foot on the bottom of the blade. It is recommended that the blade is placed on material that will not damage the blade teeth [wood or cardboard].
  • Page 39 With most guide systems, it is recommended that the back of the blade be rounded with a stone. As the machine is supplied with Laguna ceramic guides, this is not imperative, as the ceramic will round the back of the blade as it is used. However, if you decide that you want to round the back of the blade, below is a procedure.
  • Page 40 6. On certain exotic woods, the ends have been painted. This is done to control the drying. The paint is very abrasive and will dull the blade if you cut through it. It is recommended that you cut the painted ends off your wood. Using a radius chart Until you become well acquainted with your saw, it is best to use the contour (radius) chart to determine which size blade to use for a specific application.

  • Page 41: Maintenance And Troubleshooting

    Maintenance and troubleshooting All tools and machines require regular maintenance, and the bandsaw is no exception. This section details the general maintenance and care of your bandsaw. In general, we recommend that you only use a Teflon-based lubricant on the bandsaw. Regular oil attracts dust and dirt, and the Teflon tends to dry and has fewer tendencies to accumulate dirt and sawdust on your machine.
  • Page 42 2. Using a gear puller, remove the lower wheel. Take care not to damage the clamp screw thread. 3. Replace the drive belts. 4. Refit the lower wheel and re-clamp with the Allen screw. It is better to replace the drive belt(s) early than to have a breakdown during an important job.
  • Page 43 3. Attach a piece of paper to the table with scotch tape/masking tape in the area covered by the blade guide. 4. Lower the guide and mark its position on the paper. This will give you a reference point to work from.
  • Page 44 2. Internal breaker faulty. Replace the breaker. Motor tries to start but will not turn 1. With the power disconnected from the machine, open the doors and try to turn the wheel by hand. If the wheel is not turning, check the reason for the jamming. Typical reasons are: guides too tight, wood jammed in the wheel.
  • Page 45 3. Feeding the wood too fast. Slow down the feed rate. 4. Insufficient set on the teeth (wood nipping the blade). Change blade for a blade with the correct set. 5. Oil or dirt on the drive belt. Clean or replace the drive belts. 6.
