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.

SAFETY WARNINGS The employer, tool owner and tool operator: • are responsible for ensuring that the tools are kept in safe working order. • are responsible for ensuring that only qualified personnel shall repair the tool. • are responsible for ensuring that manufacturers tool maintenance instructions are available to personnel performing maintenance.
Senco strongly recommends the use of hardened nails in the JN Series tools. WORK CONTACT ELEMENT (JN91H1 / JN91H2): The moveable nose, which acts as the contact trip, is in the “depressed” position at rest to allow visibility of the nail points. When the tip of the nail is placed in the pre-punched metal connector hole and the trigger is pulled, the moveable nose moves out from the tool to detect the work surface.
When approximately five nails remain in the magazine, the workpiece contact (safety element) will be locked in the undepressed position until more nails are loaded into the magazine. Repairs other than those described here should be performed only by trained, qualified personnel. Contact SENCO for information at 1-800-543-4596.
