	Power Tool Safety Rules
	Read and understand all instructions. Failure to follow all instructions listed
! WARNING
	below, may result in electric shock, fire and/or serious personal injury.
	SAVE THESE INSTRUCTIONS

Make sure to read and understand the Owner’s Manual for your Dremel Rotary Tool Models 275, 285, 395 & 398.

Safety Rules for Routers

Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator. If cutting into existing walls or other blind areas where electrical wiring may exist is unavoidable, disconnect all fuses or circuit breakers feeding this worksite.

Always make sure the work surface is free from nails and other foreign objects.

Cutting into a nail can cause the bit and the tool to jump and damage the bit.

Never hold the workpiece in one hand and the tool in the other hand when in use. Never place hands near or below cutting surface. Clamping the material and guiding the tool with both hands is safer.

Never place tool with bit protruding through base on top of bench or work surface. Lay the tool on its side or retract the bit before setting on bench or work surface. Protruding cutting bit may cause tool to jump.

Always wear safety goggles and dust mask. Use only in well ventilated area.

Using personal safety devices and working in safe environment reduces risk of injury.

After changing the bits or making any adjustments, make sure the collet nut and any other adjustment devices are securely tightened. Loose adjustment device can unexpectedly shift, causing loss of control. Loose rotating components will be violently thrown.

Never start the tool when the bit is engaged in the material. The bit cutting edge may grab the material causing loss of control of the cutter.

Always hold the tool with two hands during startup. The reaction torque of the motor can cause the tool to twist.

The direction of feeding the bit into the material is very important and it relates to the direction of bit rotation. When viewing the tool from the top, the bit rotates clockwise. Feed direction of cutting must be counterclockwise. NOTE: Inside and outside cuts will require different feed direction. Refer to section on feeding the router. Feeding the tool in the wrong direction causes the cutting edge of the bit to climb out of the workpiece and pull the tool in the direction of the feed.

Always use the tool with the router base securely attached and positioned flat against material being cut. Having the base securely positioned on the material improves the stability and control of your tool.

Never use dull or damaged bits. Sharp bits must be handled with care. Damaged bits can snap during use. Dull bits require more force to push the tool, possibly causing the bit to break.

Never touch the bit during or immediately after use. After use, the bit is too hot to be touched by bare hands.

Never lay the tool down until the motor has come to complete stop. The spinning bit can grab the surface and pull the tool out of your control.

Do not use the tool for drilling purposes.

This tool is not intended to be used with drill bits.

Never use bits that have a cutting diameter greater than the opening in the base.

Operating Instructions

ATTACHMENT FOR USE WITH DREMEL HIGH SPEED ROTARY TOOL MODELS 275, 285, 395, & 398.

ATTENTION: This attachment will convert Dremel Rotary Tool to a Plunge Router for freehand routing, edging, grooving, and

circular cuts. The router attachment comes assembled ready for freehand or pilot bit routing.

! WARNING	This Router Attachment is
	not intended for use

under a router or saw table.

Inserting the Router Bit

The router bits are held in the tool by a collet system. The bit may be installed before or after the rotary tool is installed in the attachment.

1.Depress and hold the shaft lock button while rotating the collet nut and shaft. Continue to rotate the collet nut and shaft until the lock engages and holds the shaft (Fig. 4).

2.Use the wrench from your Dremel Rotary Tool and turn the collet nut counterclockwise to loosen it.

3.Release the shaft lock button.

Adjusting Routing Depth

NOTE: When making deep cuts, especially plunge cuts away from the edge of the workpiece, it is recommended to make several successive cuts progressively deeper using the depth adjustment and depth scale rather than making one single deep cut.

The depth limiter can be adjusted for two depths.

1.Place your Dremel Rotary Tool and Router assembly on the workpiece.

2.Turn the upper adjustment nut upward

and turn the lower adjustment nut downward so depth stop is free to move (Fig. 5).

Feeding the Router

If the router is hard to control, heats up, runs very slowly or leaves an imperfect cut, consider these causes:

•Wrong direction of feed – hard to control.

•Feeding too fast – overloads motor.

•Dull bit – overloads motor.

•Cut too large for one pass – overloads motor.

•Feeding too slow – leaves friction burns on the workpiece.

Feed smoothly and steadily (do not force). You will soon learn how the router sounds and feels when it is working best.

Rate Of Feed

When routing or doing related work in wood and plastics, the best finishes will result if the depth of cut and feed rate are regulated to keep the motor operating at high speed. Feed the router at a moderate rate. Soft materials require a faster feed rate than hard materials.

The router may stall if improperly used or overloaded. Reduce the feed rate to prevent possible damage to the tool. Always be sure the collet nut is tightened securely before use. Always use router bits with the shortest cutting length necessary to produce the desired cut. This will minimize router bit runout and chatter.

Edge Forming

When edge forming, always use piloted or bearing bits. The lower portion of a pilot tipped bit is a shaft with no cutting edges. Bearing guide bits have a ball bearing to pilot the bit.

The pilot slides along the edge of the work as the rotating blades make the cut, making decorative edges. The edge on which the

pilot slides should be perfectly smooth since any irregularities are transferred to the shaped surface.

When routing a workpiece that requires edge forming on the endgrain, always rout the endgrain edge before routing the edges that follow the grain. This minimizes the possibility of damage from any blowout at the end of the endgrain.

Router Feed Direction

The router spindle turns in a clockwise direction when viewed from above. For best control and quality of cut, feed the tool into the workpiece in the direction that the bit will tend to pull itself into the wood. Incorrect feed direction will cause the bit to try and climb over the wood.

Feed the tool in direction shown here. If cutting around the edge of a square piece, move the tool in a counterclockwise direction. If routing the inside surface as shown, move in a clockwise direction (Fig. 10).

NOTE: Feed direction is extremely important when using a pilot bit freehand on the edge of a workpiece.

Tool Lubrication

Periodic cleaning and lubrication of guide posts will keep plunge action smooth.

Depress and lock plunge router and evenly apply a light lubricant (i.e. petroleum jelly, cooking oil) to upper portion of guide posts.

Assembling the Edge Guide

For edge guide use, assemble guide rods into tool holder assembly and secure using (2) #10-24 square nuts and (2) guide rod knobs (Fig. 11).

Square nut will slide in slots above the guide rods. Guide rod knobs are assembled from the top through holes down through nuts, and against the rods. Fasten edge guide to guide rods using edge guide knobs, and hex head nuts.

Locate hex head nuts underneath edge guide and fasten with edge guide knob on top surface of edge guide. Slide edge guide

assembly on guide rods as shown. Set edge guide at desired distance from cutter and tighten edge guide knobs. (See Fig. 11 )

Edge guide is used for shaping edges, cutting rabbets, dadoes, mortise, tongues, grooves, slots, and chamfers. Remember to feed so the cutter tends to pull the edge guide against the wood. A consistent feed rate gives a smooth cut.

In general, several shallow cuts should be used when a deep groove is desired. Maximum depth of cut will vary depending on material used. Do not over feed to an amount that the motor is noticeably slowed.

Templates

Using template patterns lets you duplicate designs or letters uniformly time after time. This technique requires the use of a guide bushing.

GUIDE BUSHINGS

The guide bushing shown in (Fig. 14), is essentially a plate with a collar which is inserted into the hole in base as shown, and secured by threading a bushing plug on top of the guide bushing. The guide bushing rides along the edge of the template while the router bit, protruding below, cuts into the work.

FIG. 14

Bushing

Plug

Guide

Bushing

Base

ATTENTION: Be sure the thickness of the template is the same or larger than the length of bushing protruding below the base.

Do not use a bit that may touch the inside of the collar. Select a bit that is at least 1/16" less in diameter.

In addition, special templates are easily prepared for cutting repeated patterns, special designs, inlays, and other applications. A template pattern may be made of plywood, hardboard, metal or even plastic, and the design can be cut with a router, jigsaw, or other suitable cutting tool.

Remember that the pattern will have to be made to compensate for the distance between the router bit and the guide bushing (the “offset”), as the final workpiece will differ in size from the template pattern by that amount, due to the bit position (Fig. 15).

FREEHAND ROUTING

Many effects are gained by using the router freehand with a small diameter bit. Usually the craftsman pencils the outline or script he desires onto the work and uses the pencil line as a guide.
