Bostitch N50FN, Operation And Maintenance Manual

TOOL OPERATION

OPERATION

EYE PROTECTION which conforms to ANSI specifications and provides pro-
tection against flying particles both from the FRONT and SIDE should
ALWAYS be worn by the operator and others in the work area when loading,
operating or servicing this tool. Eye protection is required to guard against
flying fasteners and debris, which could cause severe eye injury.

The employer and/or user must ensure that proper eye protection is worn.
Eye protection equipment must conform to the requirements of the
American National Standards Institute, ANSI Z87.1-1989 and provide both
frontal and side protection. NOTE: Non-side shielded spectacles and face
shields alone do not provide adequate protection.

BEFORE HANDLING OR OPERATING THIS TOOL:

I. READ AND UNDERSTAND THE WARNINGS CONTAINED IN 

THIS MANUAL.

II. REFER TO “TOOL  SPECIFICATIONS” IN THIS  MANUAL TO 

IDENTIFY THE OPERATING SYSTEM ON YOUR TOOL.

1. TRIGGER OPERATION

A TRIGGER OPERATED tool requires a single action to drive a fastener.  Each time the 
trigger is pulled the tool will drive a fastener.  The trigger operated model is intended for 
use only when a contact trip or sequential trip cannot be used due to the requirements of 
the application.

2. CONTACT TRIP  OPERATION

The CONTACT TRIP MODEL tool contains a contact trip that operates in conjunction with 
the trigger to drive a fastener.  There are two methods of operation to drive fasteners with 
a contact trip tool.

A. SINGLE FASTENER PLACEMENT:  To operate the tool in this manner, first 

position the contact trip on the work surface, WITHOUT PULLING THE TRIGGER.  
Depress the contact trip until the nose touches the work surface and then pull the 
trigger to drive a fastener.  Do not press the tool against the work with extra force.  
Instead, allow the tool to recoil off the work surface to avoid a second unwanted 
fastener.  Remove your finger from the trigger after each operation.

B. RAPID FASTENER OPERATION:  To operate the tool in this manner, hold the 

tool with the contact trip pointing towards but not touching the work surface.  Pull 
the trigger and then tap the contact trip against the work surface using a bouncing 
motion.  Each depression of the contact trip will cause a fastener to be driven.

There are three available systems on BOSTITCH pneumatic tools.  They are:
1. TRIGGER OPERATION  2. CONTACT TRIP OPERATION   3. SEQUENTIAL TRIP OPERATION

The operator must not hold the trigger pulled on contact trip tools
except during fastening operation, as serious injury could result if the
trip accidentally contacted someone or something, causing the tool to
cycle.

Keep hands and body away from the discharge area of the tool. A
contact trip tool may bounce from the recoil of driving a fastener and
an unwanted second fastener may be driven, possibly causing injury.

3. SEQUENTIAL TRIP  OPERATION:

The SEQUENTIAL TRIP MODEL contains a contact trip that operates in conjunction
with the trigger to drive a fastener.  To operate a sequential trip tool, first position the
contact trip on the work surface WITHOUT PULLING THE TRIGGER.  Depress the
contact trip and then pull the trigger to drive a fastener.  As long as the contact trip is
contacting the work and is held depressed, the tool will drive a fastener each time the
trigger is depressed.  If the contact trip is allowed to leave the work surface, the
sequence described above must be repeated to drive another fastener.
