Tool Operation

EYE PROTECTION which conforms to ANSI specifications and provides protection against flying particles both from the FRONT and SIDE should ALWAYS be worn by the operator and others in the work area when connecting to air supply, 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 and provide both frontal and side protection. NOTE: Non-side shielded spectacles and face shields alone do not provide adequate protection.

BEFORE HANDLING OR OPERATINGTHIS TOOL:

I.READ AND UNDERSTANDTHE WARNINGS CONTAINED IN THIS MANUAL.

II.REFER TO “TOOL SPECIFICATIONS”IN THIS MANUAL TO IDENTIFY THE OPERATING SYSTEM ON YOURTOOL.

There are two available operation modes on these BOSTITCH pneumatic tools. They are:

1. SEQUENTIAL TRIP OPERATION 2. CONTACTTRIP OPERATION

OPERATION

BOSTITCH offers two types of triggers for pneumatic tools: Sequential Trip (gray trigger) and Contact Trip (black trigger). Each trigger has specific advantages. You should evaluate your particular construction project to determine which trigger is best.

Your tool was shipped from the factory in the Sequential Trip (gray trigger) configuration. It can easily be converted to the Contact Trip (black trigger) mode of operation.

1.SEQUENTIAL TRIP OPERATION (GRAYTRIGGER):

The Sequential Trip (gray trigger) gets its name from the “sequence” required to drive a fastener. To drive a fastener, the operator must first depress the “trip” FULLY against the work surface and then pull the trigger. To drive a second nail, the operator must lift the tool from the work surface, release the trigger and then repeat the above sequence.

1.The Sequential Trip (gray trigger): offers a positive safety advantage since it will not accidentally drive a fastener if the tool is bumped against any surface or anybody while the operator is holding the tools with the trigger pulled.

2.The Sequential Trip (gray trigger): allows “place nailing” without the possibility of driving a second, unwanted fastener on recoil as described below under “Contact Trip”.

2.CONTACTTRIP (CONVENTIONAL) OPERATION (BLACK TRIGGER):

Your new BOSTITCH tool can be configured for use in Contact Trip mode. To drive a nail, the “trip” and the trigger must both be depressed. In Contact Trip tools, the trigger may be depressed and held, and each “contact” between the trip and the work surface will drive a nail.

A. SINGLE FASTENER PLACEMENT (Place Nailing) -- First position the “trip” FULLY on the work surface, WITHOUT PULLING THE TRIGGER. Depress the “trip” FULLY until the nose of the tool touches the work surface and then pull the trigger to drive a nail. Do not press the tool against the work surface with extra force. Instead, allow the tool to recoil off the work surface to avoid a second unwanted fastener. Note: remove your finger from the trigger after each operation.

B. RAPID FIRE OPERATION (“Bump” Nailing) – First, hold the tool with the “trip” pointing towards but not touching the work surface. Pull the trigger and then tap or “bump” the trip against the work surface using a bouncing motion. Each depression of the “trip” will cause a nail to be driven.

N89C specifications

The Bostitch N89C is a highly regarded pneumatic roofing nailer designed to streamline the roofing process while ensuring maximum efficiency and productivity. As a staple tool in the construction industry, particularly for roofing applications, it is engineered to handle a variety of tasks with precision and ease, making it a favorite among both professionals and DIY enthusiasts.

One of the standout features of the Bostitch N89C is its lightweight design, weighing in at an impressive 4.6 pounds. This reduced weight allows for extended use without excessive fatigue, which is crucial during long working hours on steep roofs. The nailer is constructed with a durable housing that can withstand the rigors of job sites, ensuring longevity and reliable performance.

The N89C operates using a pneumatic system that delivers a powerful and consistent driving force. It is capable of accommodating wire-weld and plastic collated nails ranging from 3/4 inch to 1-3/4 inch in length, offering versatility for various roofing materials, from shingles to plywood. This adaptability makes it an essential tool for contractors who need to switch between different materials and tasks seamlessly.

Equipped with a depth adjustment feature, the Bostitch N89C allows users to control the depth at which nails are driven, ensuring proper fastening without damaging the roofing materials. This precision is vital for maintaining the integrity of roofs and ensuring longevity. An adjustable exhaust port also enhances user comfort by directing air away from the user, reducing the chance of dust and debris being blown back onto the work surface.

The Bostitch N89C's magazine holds up to 100 nails, enabling contractors to work efficiently without frequent reloading. This feature is complemented by a nail lock-out mechanism that prevents dry firing, which can cause damage to the tool and materials. The easy-to-clear jam release lever also ensures that any jams can be resolved quickly, minimizing downtime on the job.

Incorporating advanced technologies like an efficient air consumption design, the Bostitch N89C promotes longer run times and reduced compressor cycling. This innovation not only improves performance but also contributes to cost-effectiveness for contractors who rely on pneumatic tools for their jobs.

In summary, the Bostitch N89C roofing nailer is a powerful, reliable, and easy-to-use tool built for professionals. With its lightweight structure, adjustable features, and durable construction, it offers the performance needed to tackle roofing projects efficiently and effectively, making it an invaluable addition to any contractor's toolkit.
