BEFORE ASSEMBLING, MAKE SURE THAT THE SWITCH IS IN THE “OFF” POSITION AND THAT THE POWER CORD IS UNPLUGGED. DO NOT PLUG IN OR TURN ON THE MACHINE UNTIL YOU HAVE COMPLETED THE ASSEMBLY AND INSTALLATION STEPS DESCRIBED IN THIS SECTION OF THE MANUAL. INSTALLING THE PULLEY COVER A 1. B Slide the pulley cover behind the pulleys A and line up its mounting holes with the corresponding holes on the machine B. D C 2. Attach the cover to the machine using a flat washer and bolt C with a 10 mm wrench.
INSTALL THE COOLANT SYSTEM/RECOVERY TRAY FILTER The coolant system with built-in pump is designed to supply a continuous flow of liquid coolant to the cutting area to prevent overheating of both the blade and the workpiece, providing cleaner cuts and prolonging blade life. 1. B Fit the steel mesh filter A over the coolant recovery tank drain B.
MAKE SURE THE MACHINE HAS BEEN TURNED OFF AND UNPLUGGED FROM THE POWER SOURCE BEFORE PERFORMING ANY MAINTENANCE OR ADJUSTMENTS. OVERLOAD PROTECTION The magnetic safety switch on this machine is equipped with an overload protection feature. To prevent an electrical overload from damaging the motor, in the event of a spike in line voltage or amperage draw, the internal overload protector will automatically be tripped, thereby cutting off power to the motor. Common causes of such overloads: 1.
MAKE SURE THE MACHINE HAS BEEN TURNED OFF AND UNPLUGGED FROM THE POWER SOURCE BEFORE PERFORMING ANY MAINTENANCE OR ADJUSTMENTS. INSTALLING A BLADE (CONTINUED) A B 1. Lift the arm into the vertical position. Loosen the lock knob A and then push the guard down as shown. Remove the two lock knobs B and open the blade cover. 2. Loosen the blade by turning the tensioning handle counterclockwise.
MAKE SURE THE MACHINE HAS BEEN TURNED OFF AND UNPLUGGED FROM THE POWER SOURCE BEFORE PERFORMING ANY MAINTENANCE OR ADJUSTMENTS. ADJUSTING BLADE TENSION A properly tensioned blade is critical to obtaining maximum performance from any bandsaw. A properly tensioned blade will last longer and be much less likely to break prematurely.
MAKE SURE THE MACHINE HAS BEEN TURNED OFF AND UNPLUGGED FROM THE POWER SOURCE BEFORE PERFORMING ANY MAINTENANCE OR ADJUSTMENTS. ADJUSTING BLADE TRACKING (CONTINUED) SHOULDER BLADE A BLADE B 3. Loosen the blade by turning the handwheel counterclockwise. 4. Adjust the wheel tilt by turning the screw A with a 4 mm Allen key, so that the blade stays against the shoulder of the pulley. Tighten two bolts B, close the blade cover and tension the blade.
MAKE SURE THE MACHINE HAS BEEN TURNED OFF AND UNPLUGGED FROM THE POWER SOURCE BEFORE PERFORMING ANY MAINTENANCE OR ADJUSTMENTS. SQUARING THE VISE TO THE BLADE/USING THE VISE (CONTINUED) 2. To adjust the left jaw, loosen bolts A and B using a 20 mm wrench. 3. Position the jaw to the desired angle, or squared to the blade, and then tighten bolts A and B. 4. Repeat the previous steps with the right jaw using the bolts C and D. D Note: Use the vise handwheel to open or close the vise.
MAKE SURE THE MACHINE HAS BEEN TURNED OFF AND UNPLUGGED FROM THE POWER SOURCE BEFORE PERFORMING ANY MAINTENANCE OR ADJUSTMENTS. ADJUSTING THE THRUST BEARINGS The thrust bearing keeps the blade from moving back and out of position when the saw arm pushes against the workpiece. The thrust bearing must be very close to the back of the blade A to prevent damage to the blade during cutting. To adjust it, proceed as follows: A D 1/32” E B C 1.
