Safety warnings

Read and understand tool labels and manual. Failure to follow warnings will result in DEATH or SERIOUS INJURY.

Save These Instructions.

Personal Protective equipment

Use safety equipment. Always wear ANSI Z87+ safety glasses with permanently attached side shields. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions. Failure to do so could result in personal injury. Eye protection equipment must be worn by the operator and other people in the work area.

Employer is responsible to enforce the use of personal protective equipment by the tool operator and all other personnel in the work area.

Eye protection shall conform to the requirements of ANSI Z87+ and shall provide protection against flying particles both from front and side.

Hearing protection shall have Noise Reduction Rating determined in accordance with US Environmental Protection Agency Rules that is appropriate for the noise exposure. Head protection shall conform to ANSI Z89.1.

Explosion Hazard
Never use tool in an explosive atmosphere or in the presence of combustible materials such as flammable liquids, gases or dust.

Hazardous

Never use oxygen, carbon dioxide or any other bottled gas as a power source for this tool; the tool will explode and cause serious injury.

Hazardous power sources shall not be used. Explosion may occur.

Hazardous power sources include, but are not limited to:

1. Reactive gases including, but not limited to oxygen and combustible gases.
2. Pressure sources that can deliver in excess of 1.5 times the maximum air pressure of a tool or 200 psig (13.8 bar), whichever is greater, if a regulator fails.

Triggering Systems

Always select an actuation system that is appropriate for the fastener application and training of 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 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 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 operator manual to determine if this selectable trigger is provided in your fastener driving tool. This type trigger is easily identified in your Senco tool by a RED trigger or BLACK trigger with 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 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 metal connector.

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 remove finger from trigger when not driving fasteners. Never carry the tool with finger on or under trigger. Tool will eject a fastener if the safety element is bumped.

Do not actuate tool unless tool is placed firmly against the work surface.

Before operating, inspect tool to confirm:

• Use of proper power source.
• That tool is in proper working condition.
• Actuation system is on tool and how it operates.
• No misalignment or binding of moving parts.
• All conditions necessary for proper and safe tool operation.

Always assume the tool contains fasteners.

• No horseplay.
• Respect the tool as a working implement.
• Keep tool pointed away from yourself and others when connecting air to 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.

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 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 tool, care should be taken due to possibility of tool recoil after a fastener is driven.

If safety element is unintentionally allowed to re-contact work surface following a recoil, an unwanted fastener will be driven. Therefore, allow tool to recoil completely off work surface after a fastener is driven to avoid this condition.

Do not push safety element on 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 tool and work surface. The workpiece is likely to split and the fastener could fly free or ricochet and may cause injury.

Tool may eject a fastener when connected to air supply; therefore,

1. remove all fasteners from tool
2. 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 tool near workpiece contact.

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

Operating controls

Do not use tool without danger label on tool. If label is missing, damaged or unreadable, contact your SENCO representative to obtain a new label.

Never use tool if safety element, trigger or springs have become inoperable, missing or damaged. Do not tamper with or remove safety element, trigger or springs.

Disconnect tool from air before doing tool maintenance, clearing a jammed fastener, leaving 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 tool manual or approved in writing by manufacturer.

Use only parts, fasteners, and accessories recommended or sold by SENCO. Do not modify tool without authorization from SENCO.

Proper Power Source

Use only clean, dry, regulated compressed air at recommended pressure.

Do not operate the tool with any 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 tool. 200 psig Regulators shall be set at an operational pressure that is lower than or equal to 13.7 bar manufacturers specified maximum.

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 other 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 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.
