Depth Adjustment; Important Safety Instructions For All Battery Packs - DeWalt DCN660 Manual De Instrucciones

mode if contact trip is allowed to recontact work surface before trigger is released an
unwanted fastener will be fired.
• Choice of triggering method is important. Check the manual for triggering options.
SEQUENTIAL/BUMP SELECTOR SWITCH
Sequential Action (Fig. K)
• When using the tool in sequential mode mode, do not actuate the tool unless
the tool is placed firmly against the workpiece.
Bump Action (Fig. L)
• When using the tool in bump action, be careful of unin tentional double fires
resulting from tool recoil. Unwanted fasteners may be driven if the contact trip is
allowed to accidentally re-contact the work surface.
TO AVOID DOUBLE FIRES:
• Do not engage the tool against the work surface with a strong force.
• Allow the tool to recoil fully after each actuation.
• Use tool in sequential mode.
• When "bump" actuating the finish nailer, always keep tool in control. Inaccurate
placement of tool can result in misdirected discharge of a fastener.
• Do not drive nails onto the heads of other fasteners. Strong recoil, jammed
fasteners, or ricocheted nails may result. (Fig. M)
• Be aware of material thickness when using nailer. A protruding nail may cause
injury.
• DEPTH ADJUSTMENT: To reduce risk of serious injury from accidental actuation
when attempting to adjust depth, ALWAYS;
- Remove battery pack.
- Engage trigger lock.
- Avoid contact with trigger during adjustments
• Do not drive nails blindly into walls, floors or other work areas. Fasteners driven into
live electrical wires, plumbing, or other types of obstructions can result in injury. (Fig. N)
• Stay alert, watch what you are doing and use common sense when operating a
power tool. Do not use tool while tired or under the influence of drugs, alcohol,
or medication. A moment of inattention while operating power tools may result in
serious personal injury.
• Air vents often cover moving parts and should be avoided. Loose clothes, jewelry
or long hair can be caught in moving parts.
WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses.
Also use face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY
EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.
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 chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
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 microscopic particles.
• Avoid prolonged contact with dust from power sanding, sawing, grinding,
drilling, and other construction activities. 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 harmful chemicals.
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.

definitions are as follows:
V ..............................volts
Hz ...........................hertz
min.........................minutes
or DC ......... direct current
............................ Class I Construction (grounded)

Important Safety Instructions for All Battery Packs

When ordering replacement battery packs, be sure to include the catalog number and
voltage. Consult the chart at the end of this manual for compatibility of chargers and battery
packs.
The battery pack is not fully charged out of the carton. Before using the battery pack and
charger, read the safety instructions below and then follow charging procedures outlined.
READ ALL INSTRUCTIONS
• Do not charge or use the battery pack in explosive atmospheres, such as in the
presence of flammable liquids, gases or dust. Inserting or removing the battery pack
from the charger may ignite the dust or fumes.
• NEVER force the battery pack into the charger. DO NOT modify the battery pack
in any way to fit into a non-compatible charger as battery pack may rupture
causing serious personal injury. Consult the chart at the end of this manual for
compatibility of batteries and chargers.
• Charge the battery packs only in designated D
• DO NOT splash or immerse in water or other liquids.
• Do not store or use the tool and battery pack in locations where the temperature
may reach or exceed 104 °F (40 °C) (such as outside sheds or metal buildings in
summer). For best life store battery packs in a cool, dry location.
NOTE: Do not store the battery packs in a tool with the trigger switch locked on.
Never tape the trigger switch in the ON position.
WARNING: Fire hazard. Never attempt to open the battery pack for any reason. If the
battery pack case is cracked or damaged, do not insert into the charger. Do not crush, drop
or damage the battery pack. Do not use a battery pack or charger that has received a sharp
blow, been dropped, run over or damaged in any way (e.g., pierced with a nail, hit with a
hammer, stepped on). Damaged battery packs should be returned to the service center for
recycling.
