4. OPERATIONS DANGER - WARNING
THE MACHINE IS EQUIPED WITH A MAIN POWER SWITCH (located on control box 8) TO BE ACTIVATED BEFORE THE WORK OPERATION. ONCE WORK HAS BEEN COMPLETED, TURN OFF THE MAIN POWER SWITCH.
DANGER - CAUTION
• Never wear gloves while operating saw.
• Before making a new cut, always remove the cut part left from the previous
cut.
• Keep hands well away from the cutting area. DANGER - WARNING
PERFORM THE CORRECT BREAK-IN PROCEDURE AS INDICATED IN THE HEADING "BLADE REPLACEMENT”
NOTES The cutting head must be raised to the maximum up position then brought down to un-lock the head lock feature. Do not force the head down as this may damage the saw.
4.1 USE AS A MANUAL CUTTING SAW
a) Secure the workpiece to be cut in the vise using the vise adjusting screw (12) or quick release lever (14). b) Press button (located in the handle grip1) to start the blade. c) Lower the cutting head slowly until it comes into contact with the workpiece
DANGER - CAUTION To avoid breaking the blade, reduce pressure as soon as the blade comes into contact with the workpiece.
d) Complete cutting until you break through the cut. e) Release the button to stop work. f) Lift the head as far as it will go.
DANGER - CAUTION
• Never bring hands anywhere near the cutting area until the blade has stopped and head has been raised to its full height.
• Let the cut piece fall onto the base of the machine. Do not grab the cut part. DANGER - WARNING IN THE EVENT OF EXCESSIVE CUTTING PRESSURES, THE CURRENT LIMITER WILL TRIP. BACK OFF THE CUTTING PRESSURE TO SAFEGUARD THE MACHINE AND OPERATOR.
12
NOTES The cutting head must be raised to the maximum up position then brought down to un-lock the head lock feature. Do not force the head down as this may damage the saw.
4.2 USE AS AN AUTONOMOUS CUTTING SAW
a) Secure the workpiece to be cut in the vise using the vise adjusting screw (12) or quick release lever (14). Set your cutting pressure as described above. b) With the cutting head at its maximum height carefully lower the cutting head until the blade is approx. ¼” above the workpiece. c) Activate the trigger switch and trigger lock located in the hand grip to start the cutting process. d) Lower the blade onto the workpiece and let go of the handle and it will cut the part automatically. When cut is finished, the blade will automatically stop. e) When the cut is finished and the saw shuts off, raise head all the way up to lock it then remove the cut part.
DANGER – CAUTION This saw is equipped with an emergency stop button (15). In case of a problem while autonomous hands free cutting, this button can be pushed to stop all the saws functions.
5. MAINTENANCE - STORAGE - ASSISTANCE - DISPOSAL
NOTES Routine maintenance operations which can be performed by the user are described below. Have the machine repaired by qualified personnel only. This machine complies with all the relevant safety prescriptions. Repairs to the machine must be carried out by skilled personnel only using original spare parts. Failure to observe this recommendation could jeopardize user safety.
DANGER - WARNING
• BEFORE PERFORMING ANY MAINTENANCE WORK THE MACHINE MUST BE DISCONENCTED FROM THE POWER SOURCE AND LOCKED OUT.
5.1 INSTRUCTIONS FOR REPLACING THE SAW BLADE DANGER - WARNING
WEAR PROTECTIVE GLOVES.
Tools required:
- Appropriate Allen keys and/or Phillips screwdrivers are needed to replace the blade. Check the rotation of the used blade. Notice arrow direction on the head frame.
NOTES Use of used blades is not recommended.
Check the compatibility of the NEW blade for the saw.
13
NOTES The characteristics of the blade must be compatible with the technical specifications. The SE-5X6 RCT has reverse cutting technology and the teeth of the blade points forward and rotates toward the front of the saw. If the blade is not welded for reverse cutting technology, a standard blade that is reversed and inside out will also work. CAUTION must be taken when reversing the blade and is not recommended for safety.
a) Loosen the blade guide handle and slide the blade guides towards the center of the of the cutting head. Lightly tighten the handles b) Remove the rear blade cover by unscrewing the 6 thumb screws. Remove cover and put it safely out of your way.
DANGER - WARNING WHEN THE BLADE COVER IS OPENED, THE BLADE MAY JUMP OUT.
c) Turn the handwheel (2) counter clockwise to loosen and facilitate removal of the blade; d) First remove the blade from the blade wheels and then from the blade guide bearings. e) Remove and clean any chips or debris using a small brush. f) Install the new blade. g) Make sure, by means of a visual inspection, that the blade is installed with the teeth pointing in the direction indicted by the arrow on the machine; (Forward) Tighten the blade tensioning handle lightly. h) Mount the blade cover by tightening the 6 thumb screws. i) Turn the handwheel (2) clockwise to tighten blade until the clutch clicks. j) Run the blade in as described below.
DANGER - WARNING TO GET OPTIMUM PERFORMANCE FROM YOUR BLADE, CARRY OUT THE BREAK-IN PROCEDURE. ALWAYS BREAK-IN THE BLADE USING THE BLADE MANUFACTURES BREAK-IN RECOMMENDATIONS. IF UNAVAILABLE THESE STEPS WILL PROVIDE GENERIC BREAK-IN PROCEDURES.
a) Start out making three cuts, putting only a Light pressure on the workpiece.
NOTES Light pressure: as an example, consider an operation to cut a solid steel bar (e.g. C40, D .2” dia). This should be cut in about 4 minutes. Once the blade has been broken-in the same workpiece can easily be cut in about 2 minutes.
5.2 LUBRICATION / COOLANT
NOTES The machine does not need lubricating / coolant.
