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:

3. Loosen the locking hand grip (Fig. 6). Slowly lower the tool until
the router bit just touches the workpiece.
See Figure 6:

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:

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.
