Sealey SM353CE - Manual (Page 3)

 WARNING! Before operating the bandsaw ensure that you read, understand and apply the safety instructions in Section 1.
4.1. OPERATION.
NOTE: Before operating the machine certain checks and adjustments will need to be carried out. It is very important that
these instructions are followed carefully in order that the machine is set up safely and correctly.
4.1.1. check that the blade is suitable for the material to be cut.
4.1.2. check the blade for correct tension and check the blade guide bearings.
4.1.3. select the appropriate speed for the material being cut.
4.1.4. raise the blade arm and lock in position by closing hydraulic valve.
4.1.5. secure the material to be cut in the vice.
4.1.6. open hydraulic valve, lower blade arm until blade is just above workpiece, close valve and then position both blade guides as close to
the work as possible.
4.1.7. check the coolant level.
4.1.8. Plug in the saw, turn on isolating switch, switch on the coolant pump and then the saw.
DO NOT start saw with blade touching workpiece.
4.1.9. open hydraulic valve to allow blade to come down onto workpiece. Adjust feed rate as required with control knob. coolant flow may
be adjusted by control valve.
Note: If the emergency stop switch has been pressed it must be rotated to reset before the saw can be used again.
4. OPERATING INSTRUCTIONS
5. ADJUSTMENTS
 WARNING! Before following any of the steps below ensure the bandsaw is switched off, isolated from the mains power
supply and at a complete standstill. Failure to comply with this instruction can result in serious injury.
5.1. BLADE AND SPEED SELECTION.
5.1.1. refer to section 2 for the recommended setup for cutting various materials.
5.1.2. A good rule for blade selection is that three teeth should always be in contact with the workpiece, therefore, the thinner the work
piece, the more teeth the blade should have.
5.2. TO ADJUST BLADE SPEED.
5.2.1. Disconnect the machine from the power supply.
5.2.2. Loosen the wing nut on the pulley guard then lift up and swing the guard to the front of the machine.
5.2.3. release tension on the belt by turning the tension lock knob counter-clockwise and letting the motor swing forward.
5.2.4. shift the belt to the desired grooves on the pulleys. Adjust the belt tension by pulling the motor plate back until correct tension is
obtained then tighten the tension lock knob.
5.2.5. close the cover guard.
5.3. TO CHANGE BLADE AND ADJUST TENSION.
Caution: Blade teeth are sharp, handle with care.
NOTE: Proper blade tension is very important to the safe and efficient running of the bandsaw. the correct tension for the
sm353cE.V2 is between 700 to 900 kg as measured with a blade tension gauge.
NOTE: the teeth must be pointing in the correct direction (indicated on the label found on the saw arm).
5.3.1. raise saw frame to the vertical position and close the feed control valve by turning clockwise as far as it will go (Do not overtighten).
5.3.2. open both wheel covers and clean the swarf out of the machine.
5.3.3. release blade tension by turning the blade tension handwheel counter-clockwise.
5.3.4. slide the left blade guide arm to the right as far as it will go.
5.3.5. remove the blade from both wheels and out of each blade guide.
5.3.6. Install the new blade, (teeth pointing down) on the blade wheels and through the upper blade guide, working all the way up between
the blade guide bearings with the back of the blade against the back-up bearing.
5.3.7. Put light tension on the blade and work onto both wheels. (Ensure the back of the blade is against the wheel flanges of both wheels).
5.3.8. Adjust blade to the final tension. Proper tension is achieved when the pointer is on the left mark of the blade tension scale behind
the idle wheel.
5.3.9. connect the machine to the power supply and turn it on and off two to three times to ensure the blade is seated and tracking properly.
When finished close the wheel covers.
5.4. HYDRAULIC FEED ADJUSTMENT.
5.4.1. Adjust the hydraulic feed by turning the knob situated on the hydraulic cylinder.
Anti-clockwise will increase the feed rate, clockwise will decrease it.
5.4.2. to stop the flow of hydraulic fluid, turn off the hydraulic valve.
5.5. TO ADJUST THE BLADE GUIDES.
5.5.1. Loosen the adjusting knob on each blade guide and slide guide assemblies as close as possible to each side of the workpiece and re-
tighten.
5.6. TO ADJUST THE BLADE GUIDE BEARINGS.
5.6.1. raise the saw arm to a vertical position and close the hydraulic valve.
5.6.2. Loosen the hex. cap screw on the guide assembly and adjust the rear bearing to 0.025 mm from the blade.
5.6.3. Loosen lock nut and turn the front bearing eccentric so that bearing is snug with the blade. the blade should still
move up and down freely if grasped. repeat the procedure for the other guide assembly.
