Circular Saw

Safety

 * Lockout:
 * Place in locked box when not in use
 * Never leave tool plugged in
 * Never leave tool on the floor
 * PPE:
 * Eye protection required
 * Ear protection required
 * Dust mask recommended
 * Before use:
 * Ensure your material is securely clamped/fastened down
 * Ensure your planned cut does not hit anything (clamp, table, person, etc.)
 * Ensure blade intact
 * Ensure guard moves properly
 * During use:
 * Keep hands clear. Never reach down/around the work-piece while cutting
 * Use two hands on the tool at all times
 * Let blade reach full speed before moving into material
 * Position body to the side, not directly behind the saw

Usage

 * Blades:
 * Uses 7.25" blades (like this)
 * To change the blade, first unplug the saw
 * Then locate the blade lock button, press it down and turn the blade manually until it locks
 * Then use a hex key to loosen the nut on the outward face of the saw, and remove the flange
 * Replace the blade, re-seat the flange and re-tighten the nut
 * The blade should have a marked direction of rotation (it cuts on the up-cut)


 * Sawing:
 * First set the depth of cut so that the blade just barely sticks out past the bottom of the thickness of the material
 * The saw has a notch on the front to indicate the path of the blade
 * The saw is only for straight cuts. If you need curved or freehand cuts with a hand tool, use a Jigsaw
 * Careful not to overextend your arms. The last portion of the cut is the most dangerous.
 * Support the tool. When the cut is done it will want to fall down.  There will be a small window where the guard is fully open and the saw is not cutting any wood.  This is a very dangerous opportunity to slip and make a large cut in your leg.  Always be cautious, always take your time.
