require different cutting edges only the correct one is the safe one the grinder will help you to maintain your tools protect your eyes well have the safety shield in place and the tool rest at the correct angle hold small work in a visce grip Place one hand on the tool rest so you can turn the work without losing support the tool rest should always be set as close to the wheel as possible just clearing it a dirty or clogged wheel means danger a loaded wheel tends to heat up because of the extra pressure required to dress it reset the tool rest so the heel of the dresser will hook over it providing a safe guide when grinding or buffing the work should meet the wheel in the direction of rotation when you install a new wheel ring test it first a clear sound indicates IND Ates no cracks and solid Bond never hit a wheel this can weaken the bond or crack it the jointer the head turns at a speed of about 4,000 revolutions per minute each blade should be as sharp as possible never adjust the rear table and you should be sure that the material to be planed is of suff ient size to be handled safely adjust the depth of Feed in small steps too much at once will result in binding and [Music] Kickback with the machine off check the blades for defects be sure to be familiar with the working of this machine the stock should be fed to be cut with the grain and has to be free of flaws and forign material when feeding the stock stand to the left clear of [Music] [Applause] [Music] Kickback have a clean non-slip footing when your feeding hand might come close to the blade use a push stick don't take chances that might cause an accident play it safe the rotor is a hand power tool but a power tool the work should be clamped down securely you'll need both hands to handle the machine wear a face shield since chips will be flying for the jigsaw plan your work to avoid backing out of long cuts set the hold down to keep the stock firmly in place when feeding the stock keep your hands away from the blade use stock that is large enough and never remove cut offs until the saw has come to a [Music] stop before you start the band saw set the guide as close as possible above the work let the saw reach full speed before you cut feed the material slowly and don't twist the blade support round stock firmly make your own jigs if none are available never try to cut stock free hand if it doesn't lie flat on the table and don't bring your hands too close to the blade be sure to select the correct speed and blade for different materials such as aluminum and don't force a cut never remove waste before the saw has stopped completely if you hear a clicking noise it's probably a cracked blade turn off the power immediately and step back the blade might break be careful when you open the wheel guards the blade might spring out the circular saw is potentially the most dangerous tool in the shop stand well to the left to avoid being hit by a board kicking back use a push stick to feed the stock past the blade be sure the material is flat on the table and that you have a firm grip set the blades so that a few full teeth extend above the stock to be cut and make sure the guard is replaced make adjustments with the power off be sure the blade is stopped completely before removing any material and even then do not reach across the [Music] blade all adjustments should be locked and checked before you turn on the saw let the blade come to full speed first hold the stock firmly against the fence avoid cutting free [Music] hand get a firm grip on stock and miter gauge for multiple Cuts put a spacer over the fence to prevent the cut off pieces from jamming as they go past the blade ask for advice before attempting any new technique be thoroughly familiar with the things that can be done do them safely with both the metal or the wood lathe as with all tools safety has to be the first consideration dress safely loose sleeves rolled up wear safety glasses in some

dog or Chuck won't strike the carriage when it is in use the work on your wood lathe should have the spur Center solidly embedded material should be free of knots and cracks the tail stock firmly locked check for proper clearance all around allow about 1/8 of an inch then lock the tool rest select turning speeds carefully use a low speed for rough cutting and for large diameters protection of your face not only your eyes is the safe way keep the cup Center lubricated when applying the oil stop the machine release the tail stock use an oil can and reset and check everything before restarting the lathe on the metal lathe if the center begins to squeal back the tool off and stop the lathe immediately a dry Center can cause a serious accident use Sharp Tools have a good grip and solid support the lathe should be stopped when you adjust or remove the tool rest sanding is done with the tool rest removed tighten the face plate by turning it slowly with the metal lathe don't let cuting grow too long but never touch them with your bare fingers they are hot and sharp get used to filing by standing to the right of the headstock and do your filing left-handed keeping the right elbow High never wrap abrasive cloth around the work use a wooden block when removing the chuck never at any time leave the key in the Chuck these are all Simple Rules follow them and work safely
