• Actuating tool may result in flying debris, collation material, or dust which could harm the operator’s eyes. The operator and all those persons in the general area should wear safety glasses with permanently attached side shields. Approved safety glasses are imprinted with the character “Z87.1”. It is the employer’s responsibility to enforce the use of eye protection equipment by the tool operator and other people in the work area. (Fig. A)

• Always wear appropriate personal hearing and other protection during use. Under some conditions and duration of use, noise from this product may contribute to hearing loss. (Fig. A)

• Use only clean, dry, regulated air. Condensation from an air compressor can rust and damage the internal workings of the tool. (Fig. B)

• Regulate air pressure. Use air pressure compatible with ratings on the nameplate of the tool. (Not to exceed 120 psi, 8.3 bar) Do not connect the tool to a compressor rated at over 175 psi. The tool operating pressure must never exceed 175 PSI even in the event of regulator failure. (Fig. C)

• Only use air hose that is rated for a maximum working pressure of at least 150 PSI (10.3 BAR) or 150% of the maximum system pressure, whichever is greater. (Fig. D)

• Do not use bottled gases to power this tool. Bottled compressed gases such as oxygen, carbon dioxide, nitrogen, hydrogen, propane, acetylene or air are not for use with pneumatic tools. Never use combustible gases or any other reactive gas as a power source for this tool. Danger of explosion and/or serious personal injury may result. (Fig. E)

• Use couplings that relieve all pressure from the tool when it is disconnected from the power supply. Use hose connectors that shut off air supply from the compressor when the tool is disconnected. (Fig. F)

• Disconnect tool from air supply when not in use. Always disconnect tool from air supply and remove fasteners from the magazine before leaving the area or passing the tool to another operator. Do not carry tool to another work area in which changing location involves the use of scaffoldings, stairs, ladders, and the like, with air supply connected. Do not make adjustments, remove the magazine, perform maintenance or clear jammed fasteners while connected to the air supply. If the contact trip is adjusted when the tool is connected to the air supply and nails are loaded, accidental discharge may occur. (Fig. G)

• Connect tool to air supply before loading fasteners, to prevent a fastener from being fired during connection. The tool driving mechanism may cycle when tool is connected to the air supply. Do not load fasteners with trigger or contact trip depressed, to prevent unintentional firing of a fastener.

• Do not remove, tamper with, or otherwise cause the tool, trigger, or contact trip to become inoperable. Do not tape or tie trigger or contact trip in the ON position. Do not remove the spring from the contact trip. Make daily inspections for free movement of trigger and contact trip. Uncontrolled discharge could result.

• Inspect tool before use. Do not operate a tool if any portion of the tool, trigger, or contact trip is inoperable, disconnected, altered, or not working properly. Leaking air, damaged parts or missing parts should be repaired or replaced before use. (Fig. H)

• Do not alter or modify the tool in any way. (Fig. I)

• Always assume that the tool contains fasteners.

• Do not point the tool at co-workers or yourself at any time. No horseplay! Work safe! Respect the tool as a working implement. (Fig. J)

• Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control. When tool is not in use, it should be locked in a safe place, out of the reach of children.

• Remove finger from trigger when not driving fasteners. Never carry tool with finger on trigger. Accidental discharge could result. Using the trigger lock-off will prevent accidental discharge.

• Do not overreach. Maintain proper footing and balance at all times. Loss of balance may cause personal injury. (Fig. K)

• Make sure hose is free of obstructions or snags. Entangled or snarled hoses can cause loss of balance or footing.

• Use the tool only for its intended use. Do not discharge fasteners into open air, concrete, stone, extremely hard woods, knots or any material too hard for the fastener to penetrate. Do not use the body of the tool or top cap as a hammer. Discharged fasteners may follow unexpected path and cause injury. (Fig. L)

• Always keep fingers clear of contact trip to prevent injury from inadvertent release of nails. (Fig. M)

• Refer to the Maintenance and Repairs sections for detailed information on the proper maintenance of the tool

• Always operate the tool in a clean, lighted area. Be sure the work surface is clear of any debris and be careful not to lose footing when working in elevated environments such as rooftops.

• • Do not drive fasteners near edge of material. The workpiece may split causing the fastener to ricochet, injuring you or a co-worker. Be aware that the nail may follow the grain of the wood (shiner), causing it to protrude unexpectedly from the side of the work material. Drive the nail perpendicular to the grain to reduce risk of injury. (Fig. N)

• Do not drive nails onto the heads of other fasteners or with the tool at too steep an angle. Personal injury from strong recoil, jammed fasteners, or ricocheted nails may result. (Fig. O)

• Be aware of material thickness when using the nailer. A protruding nail may cause injury. • Be aware that when the tool is being utilized at pressures on the high end of its operating range, nails can be driven completely through thin or very soft work material. Make sure the pressure in the compressor is set so that nails are set into the material and not pushed completely through. (Fig. P)

• Keep hands and body parts clear of immediate work area. Hold workpiece with clamps when necessary to keep hands and body out of potential harm. Be sure the workpiece is properly secured before pressing the nailer against the material. The contact trip may cause the work material to shift unexpectedly. (Fig. Q)

• Do not use tool in the presence of flammable dust, gases or fumes. The tool may produce a spark that could ignite gases causing a fire. Driving a nail into another nail may also cause a spark. (Fig. R)

• Keep face and body parts away from back of the tool cap when working in restricted areas. Sudden recoil can result in impact to the body, especially when nailing into hard or dense material. (Fig. S)

• Grip tool firmly to maintain control while allowing tool to recoil away from work surface as fastener is driven. In “Contact Actuation 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. BUMP ACTION TRIGGER

• When using the bump action trigger, be careful of unintentional double fires resulting from tool recoil. Unwanted fasteners may be driven if the contact trip is allowed to accidentally re-contact the work surface. (Fig. T)
  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 sequential action trigger.

• When “bump” actuating the framing nailer, always keep the tool in control. Inaccurate placement of tool can result in misdirected discharge of a fastener.
  SEQUENTIAL ACTION TRIGGER

• When using the sequential action trigger, do not actuate the tool unless the tool is placed firmly against the workpiece.

• 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. U)

• 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.
  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.WARNING: ALWAYS USE SAFETY GLASSES. Everyday eyeglasses are NOT safety glasses. Also use face or dust mask if 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.

BEFORE OPERATING THIS TOOL, CAREFULLY READ AND UNDERSTAND ALL INSTRUCTIONS IN THE “IMPORTANT SAFETY INSTRUCTIONS” SECTION

ASSEMBLY

WARNING : Lock off trigger, disconnect air line from tool and remove fasteners from magazine before making adjustments or personal injury may result.

Trigger

WARNING : Keep fingers AWAY from trigger when not driving fasteners to avoid accidental firing. Never carry tool with finger on trigger. In “Contact Bump Actuation Mode” tool will fire a fastener if safety is bumped while trigger is depressed.
In accordance with the ANSI Standard SNT-101-2002, the DEWALT Nailers are assembled with a sequential action trigger. However, a bump action trigger kit is included and attached to the tool. For a replacement trigger contact your authorized service center or call 1-800-4-DEWALT.

• The gray trigger with imprinted on the side, (Cat.# D510002 kit) is the single sequential action trigger and causes the tool to operate in this mode.
• The black trigger with imprinted on the side, (Cat.# D510004 kit) is the bump action trigger and permits the tool to be actuated in this manner.
• For defining the use of the sequential action trigger and bump action trigger, see the Actuating Tool section of this manual.

Cold Weather Operation
WARNING : Read the section titled Important Safety Instructions for Pneumatic Tools at the beginning of this manual. Always wear eye and ear protection when operating this tool. Keep the nailer pointed away from yourself and others. For safe operation, complete the following procedures and checks before each use of the nailer.
When operating tools at temperatures below freezing, complete preparation procedures outlined above and follow the directions below.

1. Make sure compressor tanks have been properly drained prior to use. Always drain the compressor tanks at least once daily while using the nailer. This is especially important in cold weather because any moisture in the air in the tanks will condense in the cold temperature.
2. Keep the tool as warm as possible prior to use.
3. Put 5 to 10 drops of DEWALT Pneumatic Tool Oil or winter-weight pneumatic oil containing ethylene glycol in the end cap.
4. Lower air pressure to 80 psi or less.
5. Actuate the tool 5 or 6 times into scrap lumber to lubricate o-rings.
6. Turn pressure up to operating level (not to exceed 120 psi) and use tool as normal.
7. Re-lubricate with DEWALT Pneumatic Tool Oil or winter-weight pneumatic oil containing ethylene glycol in the end cap at least twice a day or after 4 hours of use.

Hot Weather Operation
Tool should operate normally. However, keep tool out of direct sunlight as excessive heat can damage bumpers, o-rings and other rubber parts.

Using the Lock-off (Fig. 5)
WARNING : Do not keep trigger depressed when tool is not in use. Keep the lock-off switch rotated to the right (OFF) when the tool is not in use. Serious personal injury may result.
WARNING : Lock-off trigger, disconnect air line from tool and remove fasteners from magazine before making adjustments. Serious personal injury may result. Each DEWALT nailer is equipped with a trigger lock-off switch (F). To engage the lock-off switch, rotate it to the right. To disengage the lock-off switch, center it. The trigger should always be locked off whenever any adjustments are made or when tool is not in use.

Actuating the Tool
WARNING : Always wear proper eye [ANSI Z87.1 (CAN/CSA Z94.3)] and hearing protection [ANSI S12.6 (S3.19)] when operating this tool. The tool can be actuated using one of two modes: single sequential action trigger mode and bump action trigger mode. The trigger installed on the tool as described in the Trigger section of this manual determines the mode of operation.

SEQUENTIAL ACTION TRIGGER – (GRAY)
The sequential action trigger’s intended use is for intermittent nailing where very careful and accurate placement is desired. To operate the nailer in sequential action mode:
1. Depress the contact trip firmly against the work surface.
2. Depress the trigger.

CAUTION : A nail will fire each time the trigger is depressed as long as the contact trip remains depressed.

BUMP ACTION TRIGGER – (BLACK)
The bump action trigger’s intended use is for rapid nailing on flat, stationary surfaces. Using the bump action trigger, two methods are available: place actuation and bump actuation.

1. To operate the tool using the PLACE ACTUATION method:

2. Depress the contact trip against the work surface.

3. Depress the trigger.

4. To operate the tool using the BUMP ACTUATION method:
   

5. Depress the trigger.

6. Push the contact trip against the work surface. As long as the trigger is depressed, the tool will fire a nail every time the contact trip is depressed. This allows the user to drive multiple nails in sequence.

CAUTION : Do not keep trigger depressed when tool is not in use. Keep the lock-off switch rotated to the right (OFF) when the tool is not in use.

Loading the Tool (Fig. 6)
CAUTION : Keep tool pointed in a safe direction when loading nails.
CAUTION : Never load nails with the contact trip or trigger activated.

1. Pull the nail pusher (H) back until it latches.
2. Drop appropriate collated nail sticks into loading slot on top of mag azine. See tool specifications to determine appropriate nail sizes and angles.
3. Pull the nail pusher a second time to release latch, and carefully allow the pusher to slide forward until it makes contact with the nails.

Dry Fire Lockout
To protect from internal damage, the DEWALT Framing Nailers are equipped with a dry fire lockout, which prevents the tools from actuating when the magazine is nearly empty. When approximately 4 or 5 nails remain in the magazine and the tool ceases to operate, follow the loading instructions to reload sticks of collated nails.

Depth Setting (Fig. 7)
WARNING : To reduce risk of serious injury from accidental actuation when attempting to adjust depth, ALWAYS:

• Lock OFF trigger.
• Disconnect air supply.
• Avoid contact with trigger during adjustments.

The fastener driving depth can be adjusted using the depth adjustment on the nosepiece of the tool.

1. To adjust depth setting, push button (M), slide contact trip (E) down then push button (N) in to set contact trip.
2. To sink a nail deeper, push button (M), slide contact trip (E) upward to the extent desired, then push button (N) in to set contact trip.
