Using Jointers/Planers

The jointer or jointer-planer is used to "true-up," size or smooth wood in width (edge) or thickness (surface)-doing the job of a hand plane faster and better. The jointer can also be used to perform special operations such as tapering, beveling and grooving.

Operators must be fully alert at all times when using jointer/planers.

Always wear safety goggles or safety glasses with side
shields complying with current national standard, and a full face shield when needed. Use a dust mask in dusty working conditions. Wear hearing protection during extended periods of operation.

Do not wear gloves, loose clothing, jewelry or any dangling objects that may catch in rotating parts or accessories. Tie back long hair.

Read and understand the warnings and instructions on the jointer/planer itself and in the owner/operators manual.

Check often to assure that guards return to their normal position quickly. If a guard seems slow to return or "hangs up," repair or adjust it immediately. Never use a jointer/planer without a properly operating blade guard.

Set up knives and tables in accordance with the owner/ operators manual.

Lock knives securely in place to the cutter head before start-up.

Knives must always be kept sharp.

Do not attempt to sharpen knives while they are installed in the cutterhead, unless proper attachment is provided.

Check the cutter guard and tension of cutter guard springs for proper closure.

Examine your workpiece very carefully. By all means do not joint or plane chipboard, panel board or any stock containing nails, paint or varnish.

Be very cautious of knots in wood. Knots can fly out or cause kickback. Avoid this.

When edge jointing, planning or beveling, use hold-down push blocks to keep your hands well away from the cutter head.

Never operate a jointer/planer without belt guards (if so equipped) and cutter head guards in place and working properly.

The portion of the knives of the cutter head that isn't being used should be covered at all times.

Wood narrower than 3/4 in. or thinner than 3/8 in. should not be jointed or beveled. Wood shorter than 12 in. should not be planed, jointed or beveled.

Never reach up an exhaust chute to unclog chips. Stop the tool and unplug it. Clear the chute with something other than your bare hand. The knives up there are razor sharp.

Make certain you support long lengths of stock to maintain "control." Use work supports as needed.

Feed your work with the grain. Always feed against rotation of the cutting knives.

Don't try to take off too much in one cut. Not more than 1/8 in. per cut.

Your hands should never pass over the cutter head when feeding work. The only exception if both hands are protected by hold-down push blocks that keep hands separated from the cutter head. Maintain complete alertness.

Always unplug if possible and lock the switch, if a lock is available, before changing blades or knives, making adjustments, performing maintenance jobs and when the tool is not in use. Store the key.
