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 oper-
ating power tools may result in serious personal injury.
Do not overreach. Keep proper footing and balance at all times.
