CERTIFIED SAFETYEQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratoryprotection.
WARNING:
Some dust created by power sanding,
sawing, grinding, drilling, and other construction
activities contains chemicals known to the State
of California to cause cancer, birth defects or
other reproductive harm. Some examples of these
chemicalsare:
• lead from lead‑based paints,
• crystalline silica from bricks and cement and other
masonry products, and
• arsenic and chromium from
chemically‑treatedlumber.
Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated
area, and work with approved safety equipment, such
as those dust masks that are specially designed to filter
out microscopicparticles.
• Wear protective clothing and wash exposed areas
with soap and water. Allowing dust to get into your
mouth, eyes, or lay on the skin may promote absorption
of harmfulchemicals. Direct particles away from face
andbody.
• Use the appropriate dust extractor vacuum to remove
the vast majority of static and airborne dust. Failure
to remove static and airborne dust could contaminate the
working environment or pose an increased health risk to
the operator and those in closeproximity.
• Use clamps or other practical ways to secure and
support the workpiece to a stable platform. Holding
the work by hand or against your body is unstable and may
lead to loss of control andinjury.
• Air vents often cover moving parts and should be
avoided. Loose clothes, jewelry or long hair can be caught
in movingparts.
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 knockedover.
Additional Safety Information
WARNING: Never modify the power tool or any part of
it. Damage or personal injury couldresult.
WARNING: ALWAYS use safety glasses. Everyday
eyeglasses are NOT safety glasses. Also use face or
• Do not actuate the tool unless the tool is placed
firmly against the workpiece. If the tool is not in contact
with the workpiece, the fastener may be deflected away
from yourtarget.
• Disconnect the tool from the power source when the
fastener jams in the tool. While removing a jammed
fastener, the nailer may be accidentally activated if it is
pluggedin.
• Do not use this nailer for fastening electrical cables.
It is not designed for electric cable installation and may
damage the insulation of electric cables thereby causing
electric shock or firehazards.
• Keep hands and body parts away from the discharge
area of the tool. While in use NEVER grasp the tool by the
magazine or canister, a mis‑driven nail can exit the nose
causing injury.
WARNING: If the tool has been dropped or you suspect
tool damage perform tool operation check as defined
in the mode selection section of the manual. If it
doesn’t perform according to the manual, stop using
the tool and have it serviced at an authorized DeWALT
servicecenter.
• Always wear safetyglasses.
• Always wear earprotection.
• Only use fasteners of the type specified in themanual.
• Do not use any stands for mounting the tool to asupport.
• Do not disassemble or block any parts of the fastener
driving tool such as the contacttrip.
• Prior to each operation check that the contact trip and
triggering mechanism is functioning properly and that all
nuts and bolts aretight.
• Do not use the DCN920, DCN930
ʵ when changing from one driving location to another
involving the use of scaffoldings, stairs, ladders or
ladder‑like constructions, e.g., roof laths, etc.;
ʵ when closing boxes or crates;
ʵ when fitting transportation safety systems, e.g., on
vehicles, wagons,etc.
For exemptions check your local national
workplaceregulations.
• Always check local workplaceregulations.
• Do not use the tool as ahammer.
• Never actuate the fastener driving tool into freespace.
• In the work area, carry the tool at the workplace using only
one hand, and never with the triggeractuated.
• Consider the conditions in the work area. Fasteners can
penetrate thin workpieces or slip off corners and edges of
the work piece, and thus put people atrisk.
• Do not drive fasteners close to the edge of theworkpiece.
• Do not drive fasteners on top of otherfasteners.
