•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 stapler 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 fastener into another fastener 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 fastening into hard or dense material. (Fig. S)
•Grip tool firmly to maintain control while allow- ing 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 result- ing from tool recoil. Unwanted fasteners may be driven if the contact trip is allowed to accidentally
TO AVOID DOUBLE FIRES (Fig. T):
•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 stapler, 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 (for D51422 only): To reduce risk of serious injury from accidental actuation when attempting to adjust depth,
ALWAYS:
•Lock off trigger.
•Disconnect air supply.
•Depress and hold depth adjustment lock but- ton (Fig. U1), before sliding depth adjustment bar (Fig. U2).
•Avoid contact with trigger during adjustments (Fig. V).
•Do not drive fasteners 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. W)
•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 influ- ence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.

•Se reporter à la rubrique Entretien et répara- tions pour obtenir de plus amples renseigne- ments sur l’entretien approprié de l’outil.
•Toujours utiliser l’outil dans un endroit propre et éclairé. S’assurer que la surface de travail est exempte de débris et prendre soin de ne pas per- dre l’équilibre lors de travaux en hauteur comme sur des toits.
•Ne pas enfoncer d’attaches près du bord de la pièce.
•Ne pas enfoncer d’attaches sur les têtes d’autres attaches ou avec l’outil à un angle trop aigu. Cette pratique peut se solder par une blessure corporelle provoquée par un recul, un coincement ou un ricochet d’attache. (Fig. O)
•S’informer de l’épaisseur du matériau lorsque vous utilisez une agrafeuse. Une attacher en saillie peut causer des blessures.
•Être conscient que lorsque l’outil est utilisé à des pressions du côté élevé de sa gamme de fonctionnement, les attaches peuvent passer complètement à travers un matériau mince ou très souple. S’assurer que la pression dans le compresseur est réglée de sorte que les attaches sont fixées dans le matériau et non poussées entièrement dans
•Garder les mains et les parties du corps éloignées de la zone immédiate de travail. Le cas échéant, tenir la pièce à l’aide de serres pour protéger les mains et le corps de dangers poten- tiels. S’assurer que la pièce est bien fixe avant d’appuyer l’agrafeuse contre
•Ne pas utiliser d’outil en présence de pous- sière, de gaz ou d’émanations inflammables. L’outil peut générer une étincelle qui risque d’en- flammer les gaz, provoquant ainsi un incendie. Une étincelle pourrait également être produite si une agrafe est enfoncée sur une autre agrafe. (Fig. R)
•Tenir le visage et le corps à l’écart de l’arrière du couvercle lors de travaux dans des endroits restreints. En effet, un recul inopiné peut entraîner un impact au corps, particulière- ment lors d’un agrafage dans une matière dure ou dense. (Fig. S)
•Saisir l’outil fermement pour en garder la maîtrise tout en lui permettant de reculer hors de la surface de travail lorsque l’attache est enfoncée. En « mode d’actionnement par contact », si le déclencheur touche la pièce de nouveau avec la détente enfoncée, l’agrafeuse se déclenchera.
•Le choix de la méthode de déclenchement est important. Consulter le présent mode d’emploi pour connaître les options de déclenchement.
tapa superior como un martillo. Los elementos de fijación descargados podrían hacer un camino inesperado y causar una lesión. (Fig. L)
•Siempre deje los dedos lejos del activador por contacto para evitar que se produzcan lesiones por la liberación inadvertida del impulsor. (Fig. M)
•Consulte las secciones Mantenimiento y Reparaciones para obtener información detallada sobre el mantenimiento correcto de la herramienta.
•Opere siempre la herramienta en un área limpia e iluminada. Asegúrese de que la super- ficie de trabajo esté libre de cualquier residuo y tenga cuidado de no perder el equilibrio cuando trabaje en lugares altos, como techos.
•No clave elementos de fijación cerca de los bordes del material. La pieza de trabajo puede partirse y hacer que el elemento de fijación rebote y lo lesione a usted o a un compañero de trabajo. Tenga en cuenta que el elemento de fijación podría seguir la veta de la madera y sobresalir en forma inesperada del costado del material de trabajo. Coloque la punta de cincel del elemento de fijación en forma perpendicular a la veta de la madera para reducir el riesgo de lesiones. (Fig. N)
•No clave elementos de fijación sobre otros elementos de fijación, o con la herramienta en un ángulo demasiado pronunciado. Podría producirse una lesión personal a causa de un fuerte retroceso, el atascamiento o el rebote de los elementos de fijación. (Fig. O)
•Conozca el espesor del material cuando utilice la engrapadora. Un elemento de fijación sobresaliente puede provocar una lesión.
•Tenga en cuenta que cuando se utiliza la herramienta a presiones del extremo superior del margen de operación, los elementos de fijación pueden atravesar completamente los materiales delgados o muy blandos. Asegúrese de que la presión del compresor esté definida para que los elementos de fijación se introduzcan en el material y no lo traspasen completamente. (Fig. P)
•Mantenga las manos y las partes del cuerpo fuera del área de trabajo inmediata. Sostenga la pieza de trabajo con abrazaderas cuando sea necesario para mantener las manos y el cuerpo alejados de daños potenciales. Asegúrese de que la pieza de trabajo esté bien sujetada antes de presionar la engrapadora contra el material. El activador por contacto puede hacer que el mate- rial de trabajo se mueva en forma inesperada. (Fig. Q)
•No utilice la herramienta en presencia de polvo, gases o vapores inflamables. La her- ramienta puede producir una chispa que le pren- da fuego a los gases y provoque un incendio. Clavar un elemento de fijación sobre otro tam- bién puede producir una chispa. (Fig. R)
•Mantenga la cara y las partes del cuerpo ale- jados de la parte posterior de la tapa de la her- ramienta cuando trabaje en áreas restringi- das. Un retroceso repentino puede ocasionar un impacto al cuerpo, especialmente al clavar en materiales duros o densos. (Fig. S)
