Warning: Before using the jigsaw read and understand these important safety instructions:
Danger Zone-The jigsaw danger zone is 3" out from the blade in all directions. When you're using the jigsaw as a sabre saw, the zone extends to 12" above the blade.
Wear proper eye protection.
Remember that part of the blade extends beneath the table. Never reach beneath the table to adjust the table tilt, to tighten the Mark V accessory mount lock, or for any other reason while the machine is running. Turn off the jigsaw first and let the blade come to a complete stop.
When removing jigsaw blades, remember that these blades are tensioned by a strong spring. If you loosen the locking screws in either chuck without first releasing the tension, the upper blade chuck will snap back in the tension tube, possibly damaging the jigsaw or injuring you.
Always turn the jigsaw on first, then feed the workpiece into the blade. Never turn on the machine with stock pressed up against the blade.
Don't use worn, dull or damaged blades. They have a tendency to heat up and snap while you're working.
Recondition or replace worn blade guides immediately.
If you're using a Shopsmith Power Stand, be sure you're using the proper pulley and belt combination and that the pulley and belt are properly guarded.
