debris, collation material, or dust which could harm 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 characters “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. Conden sation 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 200 psi. The tool operating pressure must never exceed 200 psi even in the event of regulator failure. (Fig. C)

English

• 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, which ever is greater. (Fig. D)

• Do not use bottled gases to power this

FIG. G

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 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 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 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

FIG. H

FIG. I

FIG. J

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 spring from 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)

English

• 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 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,

FIG. P

FIG. N

FIG. O

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)

FIG. K

FIG. L

FIG. M

English

• Keep hands and body parts clear of

FIG. Q

FIG. R

FIG. S

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.

• When using the sequential action

FIG. T

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.T)

• 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:

English

• ANSI Z87.1 eye protection (CAN/CSA/Z94.3),

• ANSI S12.6 (S3.19) hearing protection,

• NIOSH/OSHA/MSHA respiratory protection.

OPERATION Preparing the Tool (Fig. 2, 3)

WARNING: Read the section titled Important Safety Instructions

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.

1. Before you use the nailer, be sure that the compressor tanks have been properly drained.

2. Lubricate the tool following these directions:

a. Use D

EWALT pneumatic tool oil or a non-detergent S.A.E. 20

weight oil. DO NOT use detergent oil or additives as they will damage o-rings and rubber parts.

b. Use a filter-regulator-lubricator in the air line between the

compressor and the tool when possible.

c. If a lubricator is not available, add 5 to 10 drops of oil in the air

fitting a least twice a day or every 4 hours of use.

FIG. 2

FIG. 3

3. Wear proper eye, hearing and respiratory protection.

4. Remove all fasteners from the magazine.

5. Check for smooth and proper operation of contact trip and pusher assemblies. Do not use tool if either assembly is not functioning properly. NEVER use a tool that has the contact trip restrained in the up position.

6. Check air supply. Ensure that air pressure does not exceed recommended operating limits, refer to Tool Specifications.

7. Connect air hose.

8. Check for audible leaks around valves and gaskets. Never use a tool that leaks or has damaged parts.

WARNING: To reduce the risk of personal injury, disconnect tool

from air supply before performing maintenance, clearing a jammed fastener, leaving work area, moving tool to another location or handing the tool to another person.

Trigger (Fig. 1, 4)

WARNING: The operator must not hold the trigger pulled except

during fastening operation, as serious injury could result if the trip accidentally contacted someone or something, causing the tool to cycle.

WARNING: Keep hands and body away from the discharge area

of the tool.

WARNING: Never use rafter hook to hang tool from body, clothing

or belt.

The sequential triggering system gets its name from the “sequence”

required to drive a fastener.

1. Sequential Triggering: offers a positive safety advantage since it will not accidentally drive a fastener if the tool is bumped against any surface or anybody while the operator is holding the tools with the trigger pulled.

English

2. Sequential Triggering: allows “place nailing” without the

possibility of driving a second, unwanted fastener on recoil.

EWALT offers only one mode of operation with this tool.

NOTE: This tool operates sequentially, it’s operation is unique from all other D

EWALT tools. The moveable nose (D), which acts as the

contact trip, is in the “depressed” position at rest to allow visibility of the nail points used for positive placement. When the tip of the nail is placed in the preformed metal connector hole (G) and the trigger is pulled, the moveable nose moves out from the tool to detect the work surface. If the moveable nose does not detect the work surface close to the nose of the tool, the tool will not actuate.

WARNING: To avoid serious injury from fasteners and flying debris

when installing metal connectors using the mcn nailer:

• Use only genuine D

EWALT metal connector nails.

• Metal connector nails are not designed to penetrate metal. When installing metal connectors, always place the exposed point of the metal connector nail into the metal connector’s pre-formed hole, and orient so the nail is perpendicular to the hole before attempting to drive a fastener.

2. Remove nails by releasing the pusher spring and sliding nails backwards.

3. Depress the pusher (E) and slide nails past magazine tab and out the magazine.

FIG. 7

Rafter Hook (Fig. 1)

WARNING: Never use rafter hook to hang tool from body, clothing

or belt.

The integrated rafter hook (C) can be rotated to either side of the tool

to accommodate left- or right-handed users. NOTE: The rafter hook can not be removed.

Cold Weather Operation

WARNING: Read the section titled Important Safety Instructions

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

English

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 D

EWALT 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 D

EWALT 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.

Cleaning

WARNING: Blow dirt and dust out of all air vents with clean, dry air

at least once a week. To minimize the risk of eye injury, always wear

ANSI Z87.1 approved eye protection when performing this.

WARNING: Never use solvents or other harsh chemicals for

cleaning the non-metallic parts of the tool. These chemicals may weaken the plastic materials used in these parts. Use a cloth dampened only with water and mild soap. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.

Repairs

WARNING: To reduce the risk of serious personal injury, remove

nails from magazine before making any adjustments or servicing this tool.

English

WARNING: Never tamper with or disassemble contact trip (CT)

housing assembly, it can cause severe injury to the user or to bystanders. Contact trip housing must be replaced as a complete assembly only.

CAUTION: Pusher spring (constant force spring). Caution must

be used when working with the spring assembly. The spring is wrapped around, but not attached to, a roller. If the spring is extended beyond its length, the end will come off the roller and the spring will roll up with a snap, with a chance of pinching your hand.

Also the edges of the spring are very thin and could cut. Care must

also be taken to insure no permanent kinks are put in the spring as this will reduce the springs force.

Refer to the Troubleshooting Guide at the end of this section.
