ASSEMBLY

Before performing any assembly or maintenance, make sure bandsaw is turned off and unplugged from the power supply

.

BANDSAW MUST BE GROUNDED. Use a Ground Fault Interrupter (GFI). Plug the power cord to a standard 120 volt receptacle protected by a 20 amp circuit breaker.

MBS45 4.5 Inch Metal Cutting Bandsaw Assembly & Operating Instructions 6

The bandsaw comes partly assembled. It is therefore necessary to complete the assembly as follows.

Unpack and layout all the items and identify each one.

Attach lower tray, wheels and handle in this order.

Assemble vice handle to shaft on end of main base (bed) and tighten set screw.

Ensure all guards, pulley covers etc are securely attached and properly assembled.

Legs And Tray Assembly

The legs are a three-sided section, one side of which is hinged. Lay the legs on their sides, with the open ends facing each other and approx. 18" apart.

Locate the tray and attach between the legs, using the four nuts, bolts and washers supplied.

Leave the nuts finger tight at this stage.

Important: Ensure the washer is inside the leg, next to the nut. Stand the assembly upright to form a rough "A" frame. With assistance, gently lower the main body on to the legs. Firmly secure the main body to the legs, using the three nuts and bolts at the top of each leg, ensuring there is no distortion and that the assembly is completely stable.

Note that the legs may fit either way around.

Tighten the tray nuts and bolts, checking for distortion and stability.

Work Stop Assembly

A work stop is provided, which is used to allow stock pieces of equal length to be cut without having to measure each piece individually. It comprises two parts, the work stop and the mounting rod. Push the rod into the hole in the edge of the vise, and secure with the grubscrew provided.

Mount the work stop on to the rod, with the flat face towards the saw blade, and temporarily secure with the grub screw supplied, ensuring it is not pushed on too far, as it may interfere with the saw blade when it is lowered.

Miscellaneous

A handle is provided at the left end of the machine, connected to the left leg. When the machine is lifted using this handle, it will automatically pivot on to the wheels, mounted on the bottom of the right leg, allowing the machine to be maneuvered easily and quickly around a workshop.

The handle and wheel assemblies are attached a follows. Thread the ends of the handle through the corresponding holes in the left leg, and locate on the inside of the leg using the split pins provided.

The wheel assembly comprises a bracket, axle and wheels. Attach the bracket to the base of the right leg using the nuts and bolts supplied. Thread the axle through the holes at the ends of the bracket, and insert the split pins in the holes provided in the axle, which will prevent any lateral movement. Mount the wheels at each end of the axle, and locate by inserting the split pins provided in the holes at the ends of the axle.

Before use, carry out a thorough check to ensure that all parts are completely secure and properly assembled.

OPERATION

BEFORE OPERATING YOUR BANDSAW please read manual carefully

.

BLADE GUIDE BEARING ADJUSTMENT

This is the most important adjustment on your saw. It is impossible to get satisfactory work from your saw if the blade guides are not properly adjusted. The blade guide bearings for your Metal

Cutting Bandsaw are adjusted and power tested with several test cuts before leaving the factory to ensure proper setting. The need for adjustment should rarely occur when the saw is used properly. If the guides do get out of adjustment, it is extremely important to readjust immediately. If proper adjustment is not maintained, the blade will not cut straight and if the situation is not corrected, it will cause blade damage.

Because guide adjustment is a critical factor in the performance of your saw, it is always best to try a new blade to see if this will correct poor cutting before beginning to adjust the bearings. If a blade becomes dull on one side sooner than the other, for example, it will begin cutting crooked. A simple blade change should correct this problem-the more difficult guide adjustment will not.

If a new blade does not correct the problem, check the blade guides for proper spacing. There should be 0.001" clearance between the 0.025" thickness blade and guide bearings.

To obtain this clearance adjust as follows:

1. The inner guide bearing is fixed and cannot be adjusted.

2. The outer guide bearing is mounted to an eccentric bolt and can be adjusted.

3. Loosen the nut while holding bolt with a wrench.

4. Position the eccentric by turning the bolt to the desired position of clearance.

5. Tighten the nut.

6. Adjust the second blade guide bearing in the same manner.

7. The back edge of the blade should just touch the lip of the Blade Guide Bearing.

BLADE GUIDE ASSEMBLY ADJUSTMENT

The Metal Cutting Bandsaw is equipped with two adjustable blade guide assemblies. This feature will permit you to adjust the position of the blade guides for various widths of workpieces. For the most accurate cut and prolong the life of the blade, the blade guide assemblies should be adjusted to just clear the piece to be cut.

1. Place the workpiece in the vice of bandsaw and clamp tightly.

2. Adjust catch blade guide assembly to the desired position by loosening the hand knobs and positioning the guides as required.

3. Tighten the hand knobs.

ADJUSTING BLADE TENSION

1. Make sure the motor is switched off and the machine is disconnected from electricity supply.

2. Press the blade lightly with the left hand so that the rear of the blade touches the flange of the blade wheel and adjust the blade tension adjusting knob with the right hand until no blade slipping occurs.

MBS45 4.5 Inch Metal Cutting Bandsaw Assembly & Operating Instructions 8

CHANGING

SPEED

When using your Band Saw, always change the blade speed to best suit the material being cut.

1. Disconnect power. Open the pulley guard cover. Loosen the lead screw. You can now change the position of the belt to gain the desired speed. Re-set the belt tension to allow 1/2" depression of the belt when pressed in the middle of its longest run.

2. When the tension of belt is correctly adjusted, lock the motor firmly.

3. Close the pulley guard cover.

x 64 1

/2" min. 65 1/2" max. 4 tooth per inch general use blade, included.

The choice of blade pitch is governed by the thickness of the work to be cut: the thinner the workpiece, the more teeth advised. A minimum of 3 teeth should be in the workpiece at all times for proper cutting.

If the teeth of the blade are so far apart that they straddle the work, severe damage to the workpiece and to the blade can result.

CHANGING THE BLADE

Always disconnect from electricity supply before changing blade

Raise saw head to vertical position. Loosen blade tension adjusting knob sufficiently to allow the saw blade to slip off the wheels. Install the new blade as follows:

1. Place the blade in between each of guide bearings.

2. Slip the blade around the motor pulley (bottom) with the left hand and hold in position.

3. Hold the blade taut against the motor pulley by pulling the blade upward with the right hand which is placed at the top of the blade.

4. Remove left hand from bottom pulley and place it at the top side of the blade to continue the application on the upward pull on the blade.

5. Remove right hand from blade and adjust the position of the top pulley to permit left' hand to slip the blade around the pulley using the thumb, index and little finger as guides.

6. Adjust the blade tension knob clockwise until it is just right, so no blade slippage occurs. Do not tighten excessively.

7. Place 2-3 drops of oil on the blade.

8. Replace the blade guard.

NOTE: If saw will not be used for an extended period of time, you may choose to loosen the blade after use to prolong the life of the blade.

MBS45 4.5 Inch Metal Cutting Bandsaw Assembly & Operating Instructions 9

ADJUSTING THE BLADE TRACKING

This adjustment has been completed and power-tested at the factory. The need for adjustment should rarely occur when the saw is used properly. If the tracking goes out of adjustment the blade will leave the wheel and damage will result.

Increase blade tension. Decrease blade tension.

STEP 6

Adjust the blade guide according to the material size. The arrow indicates the direction of movement of the blade.

STEP

7

Adjust guide assembly to where the blade just touches the back-up bearing.

STEP 1

Loosen blade tension.

STEP 2

Loosen hex head bolts.

STEP 3

Turn simultaneously with blade tension knob so blade tracks against shoulder of pulley.

STEP 4

Lock hex head bolts.

Automatic Switch Off

STEP 5

Tighten blade tension.

At the end of the cutting cycle (horizontal use), the machine automatically switches off. This can be adjusted by moving the bracket up or down as required.

Horizontal Cutting

1 . Raise the saw head to the vertical position.

2. Open the vice to accept the piece to be cut by rotating the wheel at the end of the base

(counter clockwise).

3. Place the workpiece on the saw bed. If the piece is long, support the end.

4. Clamp the workpiece securely in the vice by rotating the hand wheel clockwise.

5. Turn the power on, letting the head down slowly onto the work. Do not drop or force.

Let the weight of the saw head provide the cutting force. The saw automatically shuts off at the end of the cut.

MBS45 4.5 Inch Metal Cutting Bandsaw Assembly & Operating Instructions 10

Vertical Cutting

Fitting the table:

Loosen the A & B Screws from the blade guide. Take away plate D.

Locking the saw in vertical position:

Rotate the bracket to an upright position, locate in notch on saw arm and tighten. If you have difficulty positioning the bracket in the notch, adjust nearby screw at bottom of saw until bracket is positioned, then tighten bracket.

MAINTENANCE

Lubricate the parts listed below using SAE30.

1. Ball Bearing – none required

2. Blade guide bearing – none required

3. Driven wheel bearing – none required

4. Vice lead screw – as needed

5. Drive gears run in the oil bath and won’t require lubricant change more than once a year. When changing, put down the head to a horizontal position and loosen screws on the gearbox. Open the cover and place pan under the right lower corner of the gear box. Slowly raise the head until the oil flows out. Lower the head and wipe up excess oil. Add lubricant until it is full. Close cover and tighten screws.

6. If saw will not be used for an extended period of time, you may choose to loosen the blade after use to prolong the life of the blade.
