Warning

Wear eye protection.

Be sure keyed washer is directly under the spindle nut and the spindle nut is tight.

Feed the workpiece against the rotation of the cutter.

Do not use awkward hand positions.

Keep fingers away from the revolving cutter. Use fixtures when necessary.

Use the overhead guard when the adjustable fence is not in place.

• 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 swatches, 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 MACHINE. 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 table below shows the correct size to use depending on cord length and nameplate

ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge, the heavier the cord.

• 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 face or dust masks 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 work when practical. It’s safer than using your hand

and it frees both hands to operate the tool.

• 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 instructions for lubricating and changing accessories.

• ALWAYS DISCONNECT THE MACHINE FROM THE POWER SOURCE BEFORE SERVICING.

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 tips or if the blade/cutter

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 repaired or replaced.

• DIRECTION OF FEED. Feed work into the cutter against the direction of rotation of the cutter only.

• NEVER LEAVE THE MACHINE RUNNING UNATTENDED. TURN POWER OFF. Don’t leave the

machine until it comes to a complete stop.

• DO NOT OPERATE this machine while tired or under the influence of drugs, alcohol, or any medication.

handle counterclockwise to loosen.

2. Raise or lower spindle to desired height by

turning handwheel (B, Figure 9).

3. Turn spindle lock handle clockwise to tighten.

Using the Fence as a Guide

Shaping with the fence is the safest and most

satisfactory method of working. This method

should always be used when work permits. Almost

all straight work can be used with the fence.

1. For most work, where a portion of the edge of

the work is not touched by the cutter, both the

front and rear fences are in a straight line, as

shown in Figure 10.

2. When removing the entire edge of the work

piece (i.e., jointing or making a full bead), the

shaped edge will not be supported by the rear

fence when both fences are in line (see Figure

11). In this case, the work piece should be

advanced to the position shown in Figure 11

and stopped.

3. Advance the rear fence to contact the work as

shown in Figure 12. This places the rear fence

in line with the cutting circle.

Shaping with Collars and Starting Pin

Follow these rules when shaping with collars and

starting pin for safest operation and best results:

1. Collars must be smooth and free from all gum

or other substances.

2. The edge of the work must be smooth. Any

irregularity in the surface which rides against

the collar will be duplicated on the shaped

surface.

3. A portion of the work's edge must remain

untouched by the cutter so that the collar will

have sufficient bearing surface. See Figure 13

for an example of insufficient bearing surface.

Figure 14 shows sufficient bearing surface.

4. The work must be heavy in proportion to the

cut being made (see Figure 15). Under no

circumstances should a small workpiece be

shaped against the collars as shown in Figure

16.

Figure 9

Figure 10

Figure 11

Figure 12

Figure 13

Figure 14

Collar Positioning

Collars may be positioned above, below, or

between two cutters:

1. When using the collar below the cutter (Figure

17), you can always observe the progress of

the cut. A disadvantage of this method is any

accidental lifting of the work will gouge the

wood and ruin the workpiece.

2. Using the collar above the cutter (Figure 18),

the cut is not affected by slight variations in the

stock's thickness. However, the cut is not

visible during the operation. Another

advantage is accidental lifting of the work

piece will not gouge the work piece. Simply

correct the mistake by repeating the operation.

3. The collar between cutters method (Figure 19)

has both the advantages and disadvantages of

the first two methods. This method is used

primarily when shaping both edges of the work

piece.

Figure 15

Figure 16

Figure 17

Figure 18

Figure 19

Starting Pin

Only experienced, advanced

users should attempt starting pin shaping! If

you have never used this method, get training

from a qualified person who is knowledgeable

in starting pin shaping!

Failure to comply may cause serious injury!

Place the starting pin in one of the two threaded

holes in the table in front of the table rings.

1. Place work piece in the first position using the

starting pin as support (see Figure 20). Swing

the work into the cutter as shown in the

second position. The work is now supported

by the collar and starting pin.

2. After starting the cut, swing the work free of

the starting pin so it rides only against the

collar (see the third position, Figure 21).

Always feed against the action of the cutter.

Lubrication

To ensure easy movement when raising and

lowering spindle, occasionally apply a drop of light

oil on outside of spindle cartridge.

Spindle cartridge bearings are pre-lubricated and

sealed. They need no further care.
