Agricultural Power Tools • General Rules • Care should be taken to use guards and to keep hands and clothing away from cutting parts of tools and equipment • All safety procedures should be followed
Band Saw • Short or sharp curves in wood require a narrow blade-1/4” or less • To help prevent the wood from binding, the miter gauge and the rip fence should not both be used at the same time
Band Saw • A band saw used to cut metal must have a speed control that will slow the blade speed, and a metal cutting blade must be used
Drills • A center punch should be used to dent the metal before starting to drill a hole in metal • The bit should be tight in the chuck, and the chuck key should be removed before using a drill
Jointer • The depth of cut should be about 1/16” each pass • The depth of cut is determined by adjusting the front in-feed table • The last pass on each edge of the board should be with the grain for a smooth cut
Planer • About 1/16” of wood should be removed on each pass • Nails, dirt, and loose knots should be removed before the board is planed • The thin end of a rough-cut board should be put in the planer first
Planer • The final pass on each side of the board should be with the grain to get a smooth finish
Portable Grinder • Operator should use both hands on the tool • It is unsafe to use a grinding wheel after one half its original diameter is worn away
Portable Saws • Operator should use both hands with a circular saw • Circular saw is used to make straight crosscuts or rip cuts in wood • Saw teeth should point toward front of saw used to cut wood
Portable Saw • Other types of portable saws include sabre, jig, scroll, and reciprocating
Radial Arm Saw • The wood remains stationary on the saw table, and the saw is pulled to the wood • The saw should be secured after each use
Sanders • Belt sander requires operator to use both hands • Belt should be turning before it is gently touched to the wood, and it should continue to run and be moved with the grain until it is lifted from the wood when finished
Sanders • After use a belt sander should be laid on it’s side • A finishing sander should be used to sand with the grain to get a smooth finish
Table Saw • If a board is ripped less than 3” wide, a push stick should be used • To get the correct board width, measure from side of fence nearest saw blade to the saw blade tooth nearest the fence • Install the correct blade for the job with the teeth pointing toward the direction of rotation of the saw motor
Abrasive cutoff saw • Uses a circular blade to cut metal
Nail gun • Used to drive nails with pneumatics
Band Saw use • Uses a thin, continuous, flexible blade to cut either curved or straight lines
Compound miter saw • A cutoff type saw used to cut angles, compound angles, and square cuts
Drills • Makes round holes through metal or wood using a bit
Drill press • Is a stationary tool used to make round holes in metal or wood using a bit
Grinder • Shapes and smoothes metal, sharpens tools or removes rust
Power Hacksaw • Uses a back and forth motion on the blade to cut metal
Hammer drill • Is used to drill holes in masonry
Jig saw • Uses a back and forth (up and down) motion blade to cut curves
Jointer • Used to straighten and smooth edges of boards or to cut bevels
Planer • Smoothes and cut lumber to exact thickness
Radial Arm Saw • The blade is moved to cut a stationary piece of wood
Reciprocating saw • Used in tight or close situations in remodeling work
Router • Used to make molding or designs in wood surfaces, dado cuts, and rabbet cuts
Sabre saw • Cuts curves in wood or other materials
Table Saw • Used to crosscut, rip, dado, or miter cut wood
