WARNING

Wear eye protection.

Always keep cutterhead and drive guards in place and in proper operating condition. Do not

remove guard for rabbeting operations.

Never make a jointing, planing, or rabbeting cut deeper than 1/8”

Always use hold-down/push blocks for jointing material narrower than 3”, or planing material

thinner than 3”.

Never perform jointing, planing, or rabbeting cuts (with jointers provided with a rabbeting guard) on

pieces shorter than 8” (203mm) in length.

• Keep guards in place and in working order.

• Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adjusting

wrenches are removed from the machine before turning it on.

• Keep the work area clean. Cluttered areas and benches invite accidents.

• Don’t use in a dangerous environment. Don’t use power tools in damp or wet locations, or expose them

to rain. Keep work area well lighted.

• Keep children away . All visitors should be kept a safe distance from the work area.

.

• Make the workshop kidproof with padlocks, master switches, or by removing starter keys.

• Don’t force the machine. It will do the job better and safer at the rate for which it was designed.

• Use the right tool. Don’t force a machine or attachment to do a job for which it was not designed.

• Use the proper extension cord. Make sure your extension cord is in good condition. When using an

extension cord, be sure to use one heavy enough to carry the current your machine will draw. An
undersized cord will cause a drop in the line voltage resulting in power loss and overheating. The
following table shows the correct size to use depending on the cord length and nameplate ampere
rating. If in doubt, use the next heavier gauge. Remember, the smaller the gauge number, the heavier
the cord.

Volts Total Length of Cord in Feet

120V 25 50 100 150
240V 50 100 200 300

AWG
14 12 Not Recommended

• Wear proper apparel. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry
which may get caught in moving parts. Nonslip footwear is recommended. Wear protective hair cover­ing to contain long hair .

• Always use safety glasses. Also use a face or dust mask if the cutting operation is dusty. Everyday
eyeglasses only have impact resistant lenses; they are not safety glasses.

• Secure work. Use clamps or a vise to hold the work when practical. It’s safer than using your hands
and it frees both hands to operate the tool.

3

• Don’t overreach. Keep proper footing and balance at all times.

• Maintain tools with care. Keep tools sharp and clean for best and safest performance. Follow instruc-

tions for lubricating and changing accessories.

• Always disconnect the machine from the power source before servicing.

• Reduce the risk of unintentional starting. Make sure the switch is in the off position before plugging in.

• Use recommended accessories. Consult the operator’s manual for recommended accessories. The

use of improper accessories may cause risk of injury to persons.

• Never stand on a machine. Serious injury could occur if the machine is tipped or if the blade is uninten­tionally contacted.

• Check damaged parts. Before further use of the machine, a guard or other part that is damaged should be
carefully checked to determine that it will operate properly and perform its intended function - check for
alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions
that may affect its operation. A guard or other part that is damaged should be properly rep aired or re­placed.

• Direction of feed. Feed work into the blade against the direction of rotation of the blade only .

• Never leave the machine running unattended. Turn power off. Don’t leave the machine until it comes to

a complete stop.

• Some dust created by power sanding, sawing, grinding, drilling and other construction activities contains
chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these
chemicals are:

* Lead from lead-based paint.
* Crystalline silica from bricks and cement and other masonry products.
* Arsenic and chromium from chemically-treated lumber.

Y our risk from these exposures varies, depending on how often you do this type of work. To reduce your
exposure to these chemicals, work in a well-ventilated area, and work with approved safety equipment,
such as those dust masks that are specifically designed to filter out microscopic particles.
