If there is a adequate amount of welded material, the limit switch will not allow the welding button to activate the operation again. g8144z/g8145z/g8146z (Manufactured since 6/11) 9. rotate the lock levers down to release the welding clamps, then rotate the clamping pressure dial to "0". 10. inspect the weld. the welded joint should be even across the width of the blade with no gaps (see figure 38). CorrectNot CorrectNot Correct figure 38. Blade welded joint examples. —if the weld is satisfactory, continue to Step 11. —if the weld is Not satisfactory, begin again at Step 2. 11. set the clamping pressure dial to 4 or greater to bring the welding clamps close together. 12. place the blade in the welding clamps with the weld centered between the clamps and re-tighten the lock levers. Note: The welding operation has left the blade joint brittle. Annealing will allow the material to cool in gradual manner, giving the weld strength and flexibility. 13. rapidly press and release—do Not hold— the annealing button two or three times until the weld zone turns dull red. 14. repeat Step 13 three to four more times, allowing the weld to cool for about 30 seconds between each repetition. 15. Allow the blade to cool, then re-inspect the weld. 16. grind away the weld flash flat on the top and bottom of the joint so that the blade will run smoothly on the wheels. Note: Make sure not to grind the teeth or blade body, or overheat the blade during grinding—this will weaken the blade. 17. re-clamp the blade in the welding clamps with the joint centered, then repeat Step 13 twice more. 18. test the strength and flexibility of the weld by bending the blade in an arc similar to that of the bandsaw wheels. the blade should bend smoothly without any angles (see figure 39). CorrectNot Correct figure 39. Correct blade weld bend for strength and flexibility. NOTICE for good metal-to-metal contact between the welding clamps and the blade, make sure the blade material and the clamps are free from any debris or flash before each use. g8144z/g8145z/g8146z -35 (Manufactured since 6/11) SECTION 5: ACCESSORIES T20501—face Shield Crown Protector 4" T20502—face Shield Crown Protector 7" T20503—face Shield Window T20452—"Kirova" Anti-Reflective S.

Schedule For optimum performance from your machine, follow this maintenance schedule and refer to any specific instructions given in this section. Daily: • Check/correct loose mounting bolts. • Check/correct damaged or dull saw blade. • Check/correct worn or damaged wires. • Clean/protect table. • Clean metal chips from upper and lower wheel areas, and empty bottom chip pan. • Correct any other unsafe condition. Monthly: • Check for V-belt tension, damage, or wear. • lubricate tension leadscrews and guide post rack. • remove the blade and clean the wheels. Cleaning Use a brush and a shop vacuum to remove chips and other debris from the machine. Keep the table rust-free with regular applications of products like g96® gun treatment, slipit®, or Boeshield® t9 (see Section 5: Accessories on Page 36 for more details). once a month, remove the blade and thoroughly clean all metal chips or built-up grease from the wheel surfaces. redress the rubber tires if necessary. When cleaning the wheel areas, empty and clean the chip pan (see figure 43). figure 43. lower wheel chip pan. Redressing Rubber Tires As the bandsaw ages, the rubber tires on the wheel may need to be redressed if they become hardened or glazed over. redressing the rubber...
