• Make sure hose is free of obstructions FIG. L

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 FIG. M 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. N

	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	FPO
	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	FIG. O

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

FIG. P

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	FIG. Q
	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	FIG. R
	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 (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/CONTACT ACTION TRIGGER

• When using the contact 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 “contact” actuating the nailer, always keep 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.

• DEPTH ADJUSTMENT: To reduce riskofseriousinjuryfromaccidental actuation when attempting to adjust depth, ALWAYS;

• Disconnect air supply

• 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. U)

OPERATION

Preparing the Tool

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.

CAUTION: NEVER spray or in any other way apply lubricants or cleaning solvents inside the tool. This can seriously affect the life and performance of the tool.

NOTE: These nailers are designed to be used without oil.

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

2.Wear proper eye, hearing and respiratory protection.

3.Remove all fasteners from the magazine.

4.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.

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

6.Connect air hose.

7.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.

FIG. 2

Mode Selection

WARNING: Always wear proper eye [ANSI Z87.1 (CAN/CSA Z94.3)] and hearing protection [ANSI S12.6 (S3.19)] when operating this tool.

WARNING: Keep fingers AWAY from trigger when not driving fasteners to avoid accidental firing. NEVER carry tool with finger on trigger. In contact mode tool will fire a fastener if safety is bumped while trigger is depressed.

The DWFP71917 features a selectable trigger system that allows the user to choose between the following modes of operation

Sequential Trip

The Sequential Trip requires the operator to hold the tool against the work before pulling the trigger. This makes accurate fastener placement easier. The Sequential Trip allows exact fastener location without the possibility if driving a second fastener on recoil as described under Contact Trip. The Sequential Trip Tool has a positive advantage because it will not accidentally drive a fastener if the tool is contacted against the work surface - or anything else - while the operator is holding the trigger pulled.

Contact Trip

The common operation procedure on “Contact Trip” tools is for the operator to contact the work surface to actuate the trip mechanism while keeping the trigger pulled, thus driving a fastener each time the work surface is contacted. This will allow rapid fastener placement on many jobs. All pneumatic tools are subject to recoil when driving fasteners. The tool may bounce, releasing the trip, and if unintentionally allowed to re-contact the work surface with the trigger still actuated (finger still holding the trigger pulled) an unwanted second fastener will be driven.

7

TO CHANGE OPERATING MODES (FIG. 1–3)

WARNING: Disconnect air line from tool and remove fasteners from magazine before making adjustments or personal injury may result.

SEQUENTIAL TRIP ACTION

Use sequential action for intermittent nailing where very careful and accurate placement is desired.

To operate the nailer in sequential action mode:

1. Rotate the trigger mode selector

(B) clockwise to the sequential action position , as shown in Figure 2.

2.Fully depress nosepiece against the work surface.

3.Pull trigger.

4.Release trigger.

5.Lift nosepiece off work surface.

6.Repeat steps 2 through 4 for next application.

WARNING: The contact trip needs to be depressed followed by a trigger pull for each fastener followed by a release of both the contact trip and trigger after each fastener.

CONTACT TRIP ACTION

Bump/contact action is intended for rapid nailing on flat, stationary surfaces.

When using bump action, two methods are available: place actuation and bump actuation.

English

FIG. 3

English

Rotate the trigger mode selector (B) counterclockwise to the contact action position , as shown in Figure 3.
