WEARING PROPER APPAREL. Do not wear loose clothing, gloves, neckties, or jewelry that can become entangled in moving parts. Always tie back or cover long hair. Wear non-slip footwear to reduce risk of slipping and losing control or accidentally contacting cutting tool or moving parts.

HAZARDOUS DUST. Dust created by machinery operations may cause cancer, birth defects, or long-term respiratory damage. Be aware of dust hazards associated with each workpiece material. Always wear a NIOSH-approved respirator to reduce your risk.

HEARING PROTECTION. Always wear hearing protection when operating or observing loud machinery. Extended exposure to this noise without hearing protection can cause permanent hearing loss.

REMOVE ADJUSTING TOOLS. Tools left on machinery can become dangerous projectiles upon startup. Never leave chuck keys, wrenches, or any other tools on machine. Always verify removal before starting!

USE CORRECT TOOL FOR THE JOB. Only use this tool for its intended purpose—do not force it or an attachment to do a job for which it was not designed. Never make unapproved modifications—modifying tool or using it differently than intended may result in malfunction or mechanical failure that can lead to personal injury or death!

AWKWARD POSITIONS. Keep proper footing and balance at all times when operating machine. Do not overreach! Avoid awkward hand positions that make workpiece control difficult or increase the risk of accidental injury.

CHILDREN & BYSTANDERS. Keep children and bystanders at a safe distance from the work area. Stop using machine if they become a distraction.

GUARDS & COVERS. Guards and covers reduce accidental contact with moving parts or flying debris. Make sure they are properly installed, undamaged, and working correctly BEFORE operating machine.

FORCING MACHINERY. Do not force machine. It will do the job safer and better at the rate for which it was designed.

NEVER STAND ON MACHINE. Serious injury may occur if machine is tipped or if the cutting tool is unintentionally contacted.

STABLE MACHINE. Unexpected movement during operation greatly increases risk of injury or loss of control. Before starting, verify machine is stable and mobile base (if used) is locked.

USE RECOMMENDED ACCESSORIES. Consult

this owner’s manual or the manufacturer for rec-

ommended accessories. Using improper accessories will increase the risk of serious injury.

UNATTENDED OPERATION. To reduce the risk of accidental injury, turn machine OFF and ensure all moving parts completely stop before walking away. Never leave machine running while unattended.

Additional Safety for Mortising Machines

The primary risks of operating a mortising machine are as follows: You can be seriously injured or killed by getting clothing, jewelry, or long hair entangled with the chisel. Your fingers can be amputated or you can be seriously cut by the chisel. You can be blinded or hurt by flying wood chips, broken cutting tools, workpieces, or tools left in chuck after adjustment. To reduce your risk of serious injury when operating this machine, completely heed and understand the following:

HAND PROTECTION. Do not place your hands

under or near chisel while spindle is in motion. Chisels are sharp and may become hot during operation! Allow chisels to cool before handling. Always use caution when handling, especially when installing or removing.

USING CORRECT MATERIALS. Mortising materials such as metals, plastics, and glass can result in serious personal injury and machine damage. Do not use machine for anything except mortising in wood.

CHISEL COMPATIBILITY. Mortising chisels can fly out of chuck at operator if not properly secured, causing serious personal injury. Make sure mortising chisel fits a minimum of

/2" into chuck.

INSPECT CUTTING TOOLS. Inspect chisels and augers for sharpness, chips, or cracks before each use. Replace dull, chipped, or cracked cutting tools immediately.

INSPECT MACHINE. Loose chisels and augers can be ejected at operator, and headstock can fall if not properly secured, causing serious personal injury. Inspect machine for smooth head casting movement, loose augers/chisels, loose nuts/bolts, and lock levers before connecting machine to power and operating. Correct any problems before use.

SECURE WORKPIECE TO TABLE. Clamp workpiece to table or secure in a vise mounted to table, so workpiece cannot unexpectedly shift or spin during operation. NEVER hold workpiece by hand during operation.

Like all machinery there is potential danger when operating this machine. Accidents are frequently caused by lack of familiarity or failure to pay attention. Use this machine with respect and caution to lessen the possibility of operator injury. If normal safety precautions are overlooked or ignored, serious personal injury may occur.

-8-

No list of safety guidelines can be complete. Every shop environment is different. Always consider safety first, as it applies to your individual working conditions. Use this and other machinery with caution and respect. Failure to do so could result in serious personal injury, damage to equipment, or poor work results.

SECTION 2: POWER SUPPLY

Before installing the machine, consider the availability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed. To minimize the risk of electrocution, fire, or equipment damage, installation work and electrical wiring must be done by an electrician or qualified service personnel in accordance with all applicable codes and standards.

or equipment damage may occur if machine is not properly grounded and connected to power

The full-load current rating is the amperage a machine draws at 100% of the rated output power. On machines with multiple motors, this is the amperage drawn by the largest motor or sum of all motors and electrical devices that might operate at one time during normal operations.

The full-load current is not the maximum amount of amps that the machine will draw. If the machine is overloaded, it will draw additional amps beyond the full-load rating.

If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result— especially if connected to an undersized circuit. To reduce the risk of these hazards, avoid overloading the machine during operation and make sure it is connected to a power supply circuit that meets the specified circuit requirements.

For your own safety and protection of

Note: Circuit requirements in this manual apply to

a dedicated circuit—where only one machine will be running on the circuit at a time. If machine will be connected to a shared circuit where multiple machines may be running at the same time, consult an electrician or qualified service personnel to ensure circuit is properly sized for safe operation.

A power supply circuit includes all electrical equipment between the breaker box or fuse panel in the building and the machine. The power supply circuit used for this machine must be sized to safely handle the full-load current drawn from the machine for an extended period of time. (If this machine is connected to a circuit protected by fuses, use a time delay fuse marked D.)

This machine is prewired to operate on a power supply circuit that has a verified ground and meets the following requirements:

Improper connection of the equipment-grounding wire can result in a risk of electric shock. The wire with green insulation (with or without yellow stripes) is the equipment-grounding wire. If repair or replacement of the power cord or plug is necessary, do not connect the equipment-grounding wire to a live (current carrying) terminal.

Check with a qualified electrician or service personnel if you do not understand these grounding requirements, or if you are in doubt about whether the tool is properly grounded. If you ever notice that a cord or plug is damaged or worn, disconnect it from power, and immediately replace it with

We do not recommend using an extension cord with this machine. If you must use an extension cord, only use it if absolutely necessary and only on a temporary basis.

Extension cords cause voltage drop, which can damage electrical components and shorten motor life. Voltage drop increases as the extension cord size gets longer and the gauge size gets smaller (higher gauge numbers indicate smaller sizes).

Any extension cord used with this machine must be in good condition and contain a ground wire and matching plug/receptacle. Additionally, it must meet the following size requirements:

Grounding & Plug Requirements

Two-prong outlets do not meet the grounding requirements for this machine.

provided—if it will not fit the outlet, have a

This machine MUST be grounded. In the event of certain malfunctions or breakdowns, grounding reduces the risk of electric shock by providing a path of least resistance for electric current.

This machine is equipped with a power cord that has an equipment-grounding wire and a grounding plug. Only insert plug into a matching receptacle (outlet) that is properly installed and grounded in accordance with all local codes and ordinances. DO NOT modify the provided plug!

Cleanup

The unpainted surfaces of your machine are coated with a heavy-duty rust preventative that prevents corrosion during shipment and storage. This rust preventative works extremely well, but it will take a little time to clean.

Be patient and do a thorough job cleaning your machine. The time you spend doing this now will give you a better appreciation for the proper care of your machine's unpainted surfaces.

There are many ways to remove this rust preventative, but the following steps work well in a wide variety of situations. Always follow the manufac-

turer’s instructions with any cleaning product you

use and make sure you work in a well-ventilated area to minimize exposure to toxic fumes.

Before cleaning, gather the following:

• Disposable rags

• Cleaner/degreaser (WD•40 works well)

• Safety glasses & disposable gloves

• Plastic paint scraper (optional)

Basic steps for removing rust preventative:

Bench Mounting

Another option is a "direct mount" (see example below) where the machine is secured directly to the workbench with lag screws and washers.

The base of this machine has mounting holes that allow it to be fastened to a workbench or other mounting surface to prevent it from moving during operation and causing accidental injury or damage.

The strongest mounting option is a "Through Mount" (see example below) where holes are drilled all the way through the workbench—and hex bolts, washers, and hex nuts are used to secure the machine in place.

The machine must be fully assembled before it can be operated. Before beginning the assembly process, refer to

Cutting a Mortise

Mortises can be cut at varying lengths depending upon the size of tenon/joint being used. We recommend staggering mortise cuts to maximize material removed (see Figure 26) and to ensure chisel does not bend/tilt during operation.

To cut a mortise:

DISCONNECT MACHINE FROM POWER!

2. Verify that chisel and fence are square (see Installing Mortising Chisel on Page 21),

and adjust as needed.

Lay out desired mortise on test piece of scrap

lumber.

Position test piece flush with fence, and set

4. depth stop (see Adjusting Depth Stop on Page 23).

HAND INJURY HAZARD! During the next step, keep fingers and hands away from chisel and auger path when cutting the mortise.

5. Adjust fence so that chisel is aligned with outline of mortise (see Figure 25).

Pulling down on the handle can be difficult on some woods. However, NEVER use a cheater pipe or handle extender on the handle. You could break the hand lever and be seriously injured.

Turn power ON. Use hand lever to feed mor-

tising chisel into test piece.

— Feed rate must be fast enough to prevent

tip of auger from burning, but slow enough to prevent motor from stalling. This speed will vary depending on wood type, moisture content, and frequency of chip clearing from mortise.

— When cutting deep mortises, make a 1"

deep cut, then back off and allow chips to clear before cutting deeper.

Note: With some chisels, noise and smoke

are normal, but we recommend using a small amount of lubrication on augers (not chisels) to keep this to a minimum. See Page 27 for more information on lubricating augers.

Once desired depth is achieved, move hand

lever to return headstock to highest position. Test piece should be held in place by holddown.

Turn power OFF.
