Intended Use; Assembly And Adjustments - DeWalt DW621 Instruction Manual

English
• Air vents often cover moving parts and should be
avoided. Loose clothes, jewelry or long hair can be
caught in moving parts.
• An extension cord must have adequate wire size
(AWG or American Wire Gauge) for safety. The smaller
the gauge number of the wire, the greater the capacity
of the cable, that is, 16 gauge has more capacity than 18
gauge. An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. When using
more than one extension to make up the total length,
be sure each individual extension contains at least the
minimum wire size. The following table shows the correct
size to use depending on cord length and nameplate
ampere rating. If in doubt, use the next heavier gauge. The
lower the gauge number, the heavier the cord.

Be sure your power supply agrees with the nameplate
marking. Voltage decrease of more than 10% will cause loss
of power and overheating. D

COMPONENTS (FIG. A)

WARNING: Never modify the power tool or any part
of it. Damage or personal injury could result.
Refer to Figure A at the beginning of this manual for a
complete list of components.

Intended Use

This heavy-duty router is designed for professional
routing applications.
DO nOT use under wet conditions or in presence of
flammable liquids or gases.
This is a professional power tool. DO nOT let children come
into contact with the tool. Supervision is required when
inexperienced operators use this tool.

ASSEMBLY AND ADJUSTMENTS


WARNING: To reduce the risk of serious personal
injury, turn unit off and disconnect it from
power source before making any adjustments or
removing/installing attachments or accessories.
An accidental start-up can cause injury.
Bit Installation and Removal (Fig. B, C)
nOTE: Always snap the collet firmly into the collet nut, (past
the retainer spring) before installing a bit.
Use the supplied wrench and the spindle lock
necessary to loosen (counterclockwise) the collet nut
FIG. B
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" (1.5 mm). Hold the spindle shaft by depressing the
spindle lock button, while firmly tightening the collet nut
with the wrench provided to prevent the bit from slipping.
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 easy to
remove the bit.
nOTE: Your router is equipped with a clear plastic cap
over the cutting area. This cap assists with dust extraction.
When installing a router bit over 1–1/8" (28 mm) in
diameter, ensure the plastic cap is removed or positioned
above the cutting portion of the bit (Fig. C).
