SAFETY WARNINGS

**Triggering Systems**
Always select an actuation system that is appropriate for the fastener application and training of the tool operator. Contact Senco at www.senco.com for information on actuation system options. Tools are manufactured with a variety of triggering systems based on tool application, fastener size, and operator preference. Please read the operating instructions so that you are familiar with the operation of each type of triggering system.

• A sequential actuation mechanism is preferred when exact fastener placement is desired or the employer/operator prefer that the tool be reset for each fastener drive. The operating controls must be activated in a specific sequence to activate the tool. If the tool has a trigger and workpiece contact, the workpiece contact must be activated before the trigger for the tool to operate. This type of trigger is easily identified in your Senco tool by a GREY trigger.
• A contact actuation mechanism is an option when rapid fastener placement is desired. This actuation system can be activated in any sequence. Additional activations can occur when any operating control is released and re-activated. This type of trigger is easily identified in your Senco tool by a BLACK trigger.
• Some tools have a selectable trigger option built into the triggering mechanism. These tools can be switched between sequential operation and contact actuation by moving a button, lever or switch. See the operator manual to determine if this selectable trigger is provided in your fastener driving tool. This type of trigger is easily identified in your Senco tool by a RED trigger or BLACK trigger with a RED switch.
• Light duty tools may have only a finger trigger and do not require a work contact element. These tools are used in specialty applications and are typically used in industrial applications.
• Light duty tools may have a dual-action trigger. The two-stage trigger must be actuated in a sequence in order to drive a fastener. This type of tool does not require a work contact element and is used for specialty applications.
• Some special application tools utilize a retracted workpiece contact mechanism. These tools are used for attaching straps to plates through pre-punched holes.
  *Trigger color designation does not apply to the metal connectors.

It is recommended that operators that are less experienced using pneumatic fastener driving tools choose a sequential mechanism until they become familiar with the tool and its operation. Please call Senco Customer Service to obtain an alternate trigger type in those tools that can be user modified to fit the application and/or level of operator experience.
Personal Safety Always removes the finger from the trigger when not driving fasteners. Never carry the tool with a finger on or under the trigger. The tool will eject a fastener if the safety element is bumped.
Do not actuate the tool unless the tool is placed firmly against the work surface.
Before operating, inspect the tool to confirm:

• Use of proper power source.
• That tool is in proper working condition.
• The actuation system is on the tool and how it operates.
• No misalignment or binding of moving parts.
• All conditions are necessary for proper and safe tool operation. Always assume the tool contains fasteners.
• No horseplay.
• Respect the tool as a working implement.
• Keep the tool pointed away from yourself and others when connecting air to the tool.
• Do not use tools 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.
• Do not overreach. Keep proper footing and balance at all times.
• Always place yourself in a firmly balanced position. Stay alert, focus on your work and use common sense when using tool.
• Keep bystanders and children away while operating the tool.
• Store idle tools out of the reach of minors or other untrained persons.
• Drive fasteners into work surface only; never into materials too hard to penetrate.
• Do not force tool. Let the tool do the work.
• Use the correct tool for the application. The correct tool will do the job better and safer.
• Tools shall be operated at the lowest pressure needed for the application. This will reduce noise levels, part wear, and energy use.
• Do not drive fasteners on top of other fasteners or with the tool at too steep of an angle; the fasteners can ricochet and may cause injury.
• When using the tool, care should be taken due to the possibility of tool recoil after a fastener is driven.
• If the safety element is unintentionally allowed to re-contact the work surface following a recoil, an unwanted fastener will be driven. Therefore, allow the tool to recoil completely off the work surface after a fastener is driven to avoid this condition.
• Do not push the safety element on a work surface until a second fastener is desired.
• Do not drive fasteners close to the edge of the work surface. Keep face and body parts away from tools and work surfaces. The workpiece is likely to split and the fastener could fly free or ricochet and may cause injury.

The tool may eject a fastener when connected to the air supply; therefore, remove all fasteners from the tool before connecting air. Do not load fasteners with trigger or workpiece contact element depressed.
Keep hands and body away from the fastener discharge area of the tool near the workpiece contact.
DANGER

1. Read and understand tool labels and manuals. Failure to follow warnings will result in DEATH or SERIOUS INJURY.
2. Operators and others in the work area MUST wear safety glasses with side shields.
3. Keep fingers AWAY from the trigger when not driving fasteners to avoid accidental firing.
4. See manual for triggering instructions.
5. NEVER point the tool at yourself or others in the work area.
6. NEVER use oxygen or other bottled gases. An explosion may occur.
7. MAX AIR PRESS. 120 PSI (8.3 BAR)

Operating Controls

Do not use tools without a danger label on the tool. If the label is missing, damaged, or unreadable, contact your SENCO representative to obtain a new label.
Never use the tool if the safety element, trigger, or springs have become inoperable, missing, or damaged. Do not tamper with or remove safety elements, triggers or springs.
Disconnect tool from the air before doing tool maintenance, clearing a jammed fastener, leaving the work area, moving tool to another location, or handing the tool to another person, when not in use or outside of the operator’s supervision.
Tools shall not be modified unless authorized in the tool manual or approved in writing by the manufacturer.
Use only parts, fasteners, and accessories recommended or sold by SENCO. Do not modify the tool without authorization from SENCO.
Proper Power Source Use only clean, dry, regulated compressed air at the recommended pressure.
Do not operate the tool with an alternate power source.
Do not connect tools to air pressure that potentially exceeds 200 psig or 13.7 bar.
Regulators shall be used to limit compressed air pressure supplied to the tool. Regulators shall be set at an operating pressure that is lower than or equal to the manufacturer’s specified maximum.
The Air hose must have a minimum working pressure rating of 150 PSIG (10.3 bar) or 150% of the maximum pressure produced in the system, whichever is higher.
The tool and air supply hose must have a hose coupling such that all pressure is removed from the tool when the coupling joint is disconnected.
Use extra caution when driving fasteners into existing walls or other blind areas to prevent contact with hidden objects or persons on another side (e.g. wires, pipes, etc.). Never use a tool that leaks air or needs repair. Never lift, pull or lower the tool by the hose. Keep the tool pointed away from yourself and others while connecting air to the tool. Never use any part of the tool (cap or main body) as a hammer. The tool could activate or become unsafe.

Read and understand all safety instructions.

The First Way:

1. Press the workpiece contact (safety element) against the work surface.
2. Pull the trigger and the fastener is driven.

The Second Way:

1. Pull and hold the trigger.
2. Depress the workpiece contact element against the work surface and drive a fastener. Each time you push the workpiece contact (safety element) against the work surface, a fastener is driven.

This mode of operation is preferred when you desire high production and rapid fastener placement.
With a Sequential Actuation (Restrictive) trigger, fasteners can only be driven one way:

1. Press the workpiece contact (safety element) against the work surface.
2. Pull the trigger.

This mode of operation is helpful when you require precise fastener placement.

Read the “Customer Satisfaction and Safety Reminder” (CSSR) in the tool and fastener boxes for safety information regarding the Contact-Actuation and Sequential trigger modes. Under certain conditions, the Sequential trigger mode may reduce the possibility of injury to you or to others working with you.
