IMPORTANT SAFETY INSTRUCTIONS

WARNING: When using electric tools, basic safety precautions should always be followed to reduce risk of fire, electric shock, and personal injury, including the following:

READ ALL INSTRUCTIONS

Double Insulation

Double insulated tools are constructed throughout with two separate layers of electrical insulation or one double thickness of insulation between you and the tool's electrical system. Tools built with this insulation system are not intended to be grounded. As a result, your tool is equipped with a two prong plug which permits you to use extension cords without concern for maintaining a ground connection.

NOTE: Double insulation does not take the place of normal safety precautions when operating this tool. The insulation system is for added protection against injury resulting from a possible electrical insulation failure within the tool.

CAUTION: WHEN SERVICING USE ONLY IDENTICAL REPLACEMENT PARTS. Repair or replace damaged cords.

Safety Instructions For All Tools

• KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.
• CONSIDER WORK AREA ENVIRONMENT. Don't expose power tools to rain. Don't use power tools in damp or wet locations. Keep work area well lit. Do not use tool in presence of flammable liquids or gases.
• GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded surfaces. For example; pipes, radiators, ranges, and refrigerator enclosures.
• KEEP CHILDREN AWAY. Do not let visitors contact tool or extension cord. All visitors should be kept away from work area.
• STORE IDLE TOOLS. When not in use, tools should be stored in dry, and high or locked-up place — out of reach of children.
• DON'T FORCE TOOL. It will do the job better and safer at the rate for which it was intended.
• USE RIGHT TOOL. Don't force small tool or attachment to do the job of a heavy-duty tool. Don't use tool for purpose not intended.
• DRESS PROPERLY. Do not wear loose clothing or jewelry. They can be caught in moving parts. Rubber gloves and non-skid footwear are recommended when working outdoors. Wear protective hair covering to contain long hair.
  • USE SAFETY GLASSES. Also use face or dust mask if operation is dusty.
• DON'T ABUSE CORD. Never carry tool by cord or yank it to disconnect from receptacle. Keep cord from heat, oil, and sharp edges.
• SECURE WORK. Use clamps or a vise to hold work. It's safer than using your hand and it frees both hands to operate tool.
  • DON'T OVERREACH. Keep proper footing and balance at all times.
• MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and safer performance. Follow instructions for lubricating and changing accessories. Inspect tool cords periodically and if damaged, have repaired by authorized service facility. Inspect extension cords periodically and replace if damaged. Keep handles dry, clean, and free from oil and grease.
• DISCONNECT OR LOCK OFF TOOLS when not in use, before servicing, and when changing accessories, such as blades, bits, cutters.
• REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see

that keys and adjusting wrenches are removed from tool before turning it on.

- AVOID UNINTENTIONAL STARTING. Don't carry tool with finger on switch. Be sure switch is off when plugging in.

- EXTENSION CORDS. 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 product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The following table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

OPERATING INSTRUCTIONS

Bit Installation and Removal

TURN OFF AND UNPLUG ROUTER.

Before installing a router bit in your unit, position the tool so that the collet is easily accessible.

IMPORTANT NOTE: Always snap the collet firmly into the collet nut, (past the retainer spring) before installing a bit.

Depress the spindle lock button and use the supplied wrench as necessary to loosen (counterclockwise) the collet nut, as shown in Figure 1.

Insert the round shank of the desired router bit into the loosened collet as far as it will go and then pull it out about 1/16". Hold the spindle shaft by depressing the spindle lock button while firmly tightening the collet nut with the wrench, as shown in Figure 1.

Your router has a unique locking system for retaining the bit. When removing a bit, the collet nut must be loosened with the wrench.

The collet nut will turn approximately 3/4 of a turn and then become tight again. At this point the bit can't be removed. Using the same procedure, loosen the nut a second time. This lifts the collet and makes it very easy to remove the bit.

Collets

NEVER TIGHTEN THE COLLET ON THIS TOOL WITHOUT FIRST INSTALLING A ROUTER BIT IN IT. TIGHTENING AN EMPTY COLLET CAN DAMAGE THE COLLET.

To change collets, unscrew the collet assembly, as described above, sharply pull the old collet out of the collet nut and insert the new collet. Push firmly so that it snaps past the retainer spring in the collet nut.

Figure 1

Controls

IMPORTANT NOTE: Before operating any of the controls, read this whole section.

Plunge Clamp Knob

The plunge clamp knob controls the plunging action of the router. When tightened, the knob clamps the router in position, whether plunged fully down, fully up or anywhere in between. When loosened, the clamp is released and the router can be moved into and out of the workpiece.

Multi-Position Turret Stop

The turret stop limits the downward distance that the tool can be plunged. It consists of three screws of different lengths that serve to define the depth of cut by limiting the travel of the depth control rod (see Figure 2). Routing depth can be set by selecting the screw of the appropriate length on the turret. It is the interaction of the depth control rod and the turret stop that determine the routing depth.

If none of the provided screws seems close to the desired height each can be adjusted by loosening the hex nut at the bottom and then turning the screw either in or out to make it the proper length. After adjusting this screw be sure to tighten the hex nut at the bottom. (See Figure 3.)

See the section "Setting the Routing Depth for instructions on how to use the turret stop in an actual operation.

Depth Control Rod and Depth Scale

The depth control rod is what contacts the selected screw in the turret stop to limit the routing depth. (See "Setting the Routing Depth".)

Familiarization

Please take a little time now and, without plugging the tool in, practice with these adjustments and controls and become familiar with their operation. Only with a complete, "hands on" understanding of these systems will you be able to get the most out of this quality router.

Setting the Routing Depth

TURN OFF AND UNPLUG THE ROUTER.

To set the routing depth follow the steps below:

1. Install the desired router bit as described previously.
2. Loosen the depth control rod clamp knob and raise the depth control rod so that the red indicator line is at the 2 inch mark on the scale, as shown in Figure 4.
3. Rotate the turret stop until the shortest of the three screws is directly beneath the depth control rod. NOTE: the turret stop has a detent in each of its positions so that you will feel it snap into place.
4. Loosen the plunge clamp knob and push the router down until the bit just touches the surfaces to be routed. Lock the router down by tightening the plunge clamp knob.
5. Loosen the depth control rod clamp knob and permit the rod to fall and contact the screw in the turret stop that you just adjusted.
6. Read the scale by aligning the top or bottom of the red line with the 1/16" graduations on the scale. NOTE: It makes no difference whether you read the top or the bottom of the red line, as long as you consistently read the same side.
7. Using the reading you just took as the zero point, raise the rod by hand to a reading that will give the correct depth of cut. Tighten the depth control rod clamp knob.

Diagram showing a circular object with directional arrows and a rectangular block, labeled Figure 8 (no text or symbols on the diagram itself)

EXAMPLE: If the zero reading is 1-1/8" and you wish to rout to a depth of 1/2", set the red line to read 1-5/8".
8. Loosen the plunge clamp knob and release the router to rise to its full height.
The router is now ready to cut to its set depth. When it reaches the set depth, The depth control rod will contact the screw in the turret stop and stop the router's downward travel.

Using the Turret Stop for Sequential Routing Depth Settings

TURN OFF AND UNPLUG ROUTER.

It is recommended that particularly deep grooves be cut with several passes rather than one deep pass. In order to do this and still maintain accuracy of depth when the job is finished, perform the following procedure.
1. Set the final desired routing depth as instructed above. For the purpose of this discussion, assume that the desired depth is 1/2" .

1. With a depth of 1/2" set on the shortest screw in the turret stop, adjust the second shortest screw to a point about halfway between the bottom of the depth control rod and the top of the shortest screw, as shown in Figure 5.
2. Leave the vernier setting alone and turn the adjusted second shortest screw into position under the depth control rod.
3. Make your first cut at this setting.
4. Rotate the turret stop so that the shortest screw is directly under the depth control rod and make your final cut.

NOTE: The third screw in the turret stop is provided if your cut is even deeper and you want to make three cuts to achieve the final depth, or set final depth for multiple cuts at one time.

Switch

The slide switch on your router is located as shown in Figure 6. To turn the tool on, slide the switch down. To turn the tool off, slide the switch up.

Electronic Speed Control Dial

The speed of your router is variable. Use the electronic speed control dial (Figure 10) to produce uniform cutting results in wood, plastics and aluminum. Use the lower settings (1-3) for large diameter cutters and the higher settings for small diameter cutters.

Operation

After setting the cutting depth as described, locate the router such that the bit is directly over the place you will be cutting. Loosen the plunge clamp knob. With the router running, lower the unit smoothly down into the workpiece. (DO NOT JAM THE ROUTER DOWN). When the tool reaches the preset depth, tighten the plunge clamp knob. When you have finished routing, loosen the knob and let the spring lift the router directly out of the workpiece.

All common routing tasks can be performed with ease with the plunge cut router: Grooving, rabbeting, recessing, veining, and profiling on all types of wood and plastic.

Always feed the router opposite to the direction in which the cutter is rotating. Only carbide-tipped cutters should be used on panels faced with plastic laminates. The hard laminates will quickly dull steel cutters.

Direction of Feed

The direction of feed is very important when routing and can make the difference between a successful job and a ruined project. Figures 7 and 8 show proper direction of feed for some typical cuts.

Mold the outside edge of a piece of stock by (A) mold the end grain, left to right. (B) do the straight grain side moving left to right. Always do end grains first.

The direction of feed is important in router usage. Be sure the cutter is rotating into the stock by moving left to right on outside edges and clockwise on the inside cuts.

Template Guide Adapter

Your router comes equipped with a template guide adapter for use with two piece bushings and for a little extra base support.

The guide adapter will have to be removed when inserting some of the larger router bits. When not in use, remove the template guide adapter and store it (and its mounting screws) in a safe place.
