Intended Use; Assembly And Adjustments - DeWalt DW621 Instruction Manual


WARNING: Use of this tool can generate and/
or disperse dust, which may cause serious and
permanent respiratory or other injury. Always use
NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure. Direct particles
away from face and body.

WARNING: Always wear proper personal hearing
protection that conforms to ANSI S12.6 (S3.19)
during use. Under some conditions and duration
of use, noise from this product may contribute to
hearing loss.

CAUTION: When not in use, place tool on its side
on a stable surface where it will not cause a
tripping or falling hazard. Some tools with large
battery packs will stand upright on the battery pack
but may be easily knocked over.
Air vents often cover moving parts and should be
•
avoided. Loose clothes, jewelry or long hair can be
caught in moving parts.
• Do not operate this tool for long periods of time.
Vibration caused by tool action may be harmful to your
hands and arms. Use gloves to provide extra cushion and
limit exposure by taking frequent rest periods.
An extension cord must have adequate wire size
•
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
if this tool does not operate, check power supply.
