GENERAL SAFETY INSTRUCTIONS
WARNING READ ALL INSTRUCTIONS.
Failure to follow all instructions listed below may result in electric shock,
fire and/or serious injury. The term “power tool” in all of the warnings
listed below refers to your mains-operated (corded) power tool.
WORK AREA
a. Keep work area clean and well lit. Cluttered and dark areas invite
accidents.
b. Do not operate power tools in explosive atmospheres, such as in the
presence of flammable liquids, gases or dust. Power tools create sparks which
may ignite the dust or fumes.
c. Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
ELECTRICAL SAFETY
a. P ower tool plugs must match the outlet. Never modify the plug in any way.
Do not use any adapter plugs with earthed (grounded) power tools. Unmodified
plugs and matching outlets will reduce risk of electric shock.
b. Avoid body contact with earthed or grounded surfaces such as pipes,
radiators, ranges and refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
c. Do not expose power tools to rain or wet conditions. Water entering a power
tool will increase the risk of electric shock.
d. Do not abuse the cord. Never use the cord for carrying, pulling or
unplugging the power tool. Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords increase the risk of electric shock.
e. When operating a power tool outdoors, use an extension cord suitable for
outdoor use. Use of a cord suitable for outdoor use reduces the risk of
electric shock.
f. If operating a power tool in a damp location is unavoidable, use an earth
leakage circuit breaker. Use of an earth leakage circuit breaker reduces the
risk of electric shock.
PERSONAL SAFETY
a. Stay alert, watch what you are doing and use common sense when operating a
power tool. Do not use a power tool while you are tired or under the influence
of drugs, alcohol or medication. A moment of inattention while operating power
tools may result in serious personal injury.
b. Use safety equipment. Always wear eye protection. Safety equipment such as
dust mask, non-skid safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
c. Avoid accidental starting. Ensure the switch is in the off position before
plugging in. Carrying power tools with your finger on the switch or plugging
in power tools that have the switch on invites accidents.
d. Remove any adjusting key or wrench before switching the power tool on. A
wrench or a key left attached to a rotating part of the power tool may result
in personal injury.
e. Do not overreach. Keep proper footing and balance at all times. This
enables better control of the power tool in unexpected situations.
f. Dress properly. Do not wear loose clothing or jewellery. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewellery or long
hair can be caught in moving parts.
g. If devices are provided for the connection of dust extraction and
collection facilities, ensure these are connected and properly used. Use of
these devices can reduce dust related hazards.
h. Do not work materials containing asbestos (asbestos is considered
carcinogenic).
i. Take protective measures when during work dust can develop that is harmful
to one’s health, combustible or explosive (some dusts are considered
carcinogenic); wear a dust mask and work with dust/ chip extraction when
connectable.
POWER TOOL USE AND CARE
a. Do not force the power tool. Use the correct power tool for your
application. The correct power tool will do the job better and safer at the
rate for which it was designed.
b. Do not use the power tool if the switch does not switch it on and off. Any
power tool that cannot be controlled with the switch is dangerous and must be
repaired.
c. Disconnect the plug from the power source before making any adjustments,
changing accessories, or storing power tools. Such preventive safety measures
reduce the risk of starting the power tool accidentally.
d. Store idle power tools out of the reach of children and do not allow
persons unfamiliar with the power tool or these instructions to operate the
power tool. Power tools are dangerous in the hands of untrained users.
e. Maintain power tools. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the power tools
operation. If damaged, have the power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
f. Keep cutting tools sharp and clean. Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
g. Use the power tool, accessories and tool bits etc., in accordance with
these instructions and in the manner intended for the particular type of power
tool, taking into account the working conditions and the work to be performed.
Use of the power tool for operations different from those intended could
result in a hazardous situation.
SERVICE
a. Have your power tool serviced by a qualified repair person using only
identical replacement parts. This will ensure that the safety of the power
tool is maintained.

The router attachment comes assembled ready for freehand or pilot bit routing.
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.
WARNING This Router Attachment is not intended for use under a router or saw
table.
Accessories specification
See Figure 4A.
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.
4. Insert the router bit into the collet as deep as possible to ensure proper
gripping of the bit and to minimize run out. Do not insert the bit so far that
bit flutes touch the collet or collet nut to avoid chipping or cracking the
bit.
NOTE: Never place the 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.
5. Re-engage the shaft lock button and tighten the collet nut; first by hand,
then using the wrench until bit is held securely.

ADJUSTING ROUTING DEPTH
NOTE: When making deep cuts, especially plunge cuts away from the edge of
the work-piece, 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
down-ward so depth stop is free to move (Fig. 5).
See Figure 5
A Depth-Stop
B Upper Adjustment Nut
C Lower Adjustment Nut
3. Loosen the locking hand grip (Fig. 6). Slowly lower the tool until the
router bit just touches the workpiece.
See Figure 6
A Hand Grip
B Release Button
4. Tighten the locking hand grip to lock the tool in place.
5. Press and hold the release button so depth stop touches the router base.
1st Routing Depth
6. Turn the depth stop upwards so that measurement X equals the first desired
routing depth (Fig. 7).
NOTE: 1 turn equals .06″ (1.5 mm)
See Figure 7
A Depth Stop
B Upper Adjustment Nut
7. Turn the upper adjustment nut down snug against the router frame.
2nd Routing Depth
8. Turn the depth stop upwards so that measurement X equals the second
desired routing depth. Make sure upper adjustment nut turns with the depth
stop, so it rises away from router frame (Fig. 8).
See Figure 8
A Depth Stop
B Lower Adjustment Nut
9. Turn the lower adjustment nut up snug against the router frame.
NOTE: The upper adjustment nut must remain stationary when tightening the
lower adjustment nut.
10. Press the release button to select the 1st or 2nd routing depth (Fig. 9).
NOTE: The adjustment of each routing depth should be checked with a trial cut
and re-adjusted as necessary.
See Figure 9
A Release button
When routing is complete, loosen the hand grip and return the router to the
top position.
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.
See Figure 10
A Router Feed direction B Router End Grains First C Bit Rotation
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 overfeed to
an amount that the motor is noticeably slowed.

Slide the flattened side of the edge guide along the work surface.
CIRCLE GUIDE
Routing Arcs and Circles
1. Remove the edge guide and attach the circle guide bracket to the guide
rods (Fig. 13).
See Figure 13
A Finishing Nail
B Edge Guide
2. Use the finishing nail provided as a compass point. Set the circle guide
for the desired radius.
3. Place the nail through the hole in the guide and place the nail at the
center of the desired radius to be cut.
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.
See Figure 14:
A Bushing Plug
B Guide Bushing
C 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 2 mm 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).
See Figure 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.
