SAFETY INSTRUCTIONS

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.

CAUTION: Additional Safety Protection will be required in some environments. For example, the working area may include exposure to noise level which can lead to hearing damage. The employer and user must ensure that any necessary hearing protection is provided and used by the operator and others in the work area. Some environments will require the use of head protection equipment. When required, the employer and user must ensure that head protection conforming to ANSI Z89.1 is used.

AIR SUPPLY AND CONNECTIONS

Do not use oxygen, combustible gases, or bottled gases as a power source for this tool as tool may explode, possibly causing injury.

Do not use supply sources which can potentially exceed 200 P.S.I.G. as tool may burst, possibly causing injury.

The connector on the tool must not hold pressure when air supply is disconnected. If a wrong fitting is used, the tool can remain charged with air after disconnecting and thus will be able to drive a fastener even after the air line is disconnected possibly causing injury.

Do not pull trigger or depress contact arm while connected to the air supply as the tool may cycle, possibly causing injury.

Always disconnect air supply: 1.) Before making adjustments; 2.) When servicing the tool; 3.) When clearing a jam; 4.) When tool is not in use; 5.) When moving to a different work area, as accidental actuation may occur, possibly causing injury.

LOADING TOOL

When loading tool: 1.) Never place a hand or any part of body in fastener discharge area of tool; 2.) Never point tool at anyone; 3.) Do not pull the trigger or depress the trip as accidental actuation may occur, possibly causing injury.

OPERATION

Always handle the tool with care: 1.) Never engage in horseplay; 2.) Never pull the trigger unless nose is directed toward the work; 3.) Keep others a safe distance from the tool while tool is in operation as accidental actuation may occur, possibly causing injury.

The operator must not hold the trigger pulled on contact arm 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 arm tool may bounce from the recoil of driving a fastener and an unwanted second fastener may be driven possibly causing injury.

Check operation of the contact arm mechanism frequently. Do not use the tool if the arm is not working correctly as accidental driving of a fastener may result. Do not interfere with the proper operation of the contact arm mechanism.

Do not drive fasteners on top of other fasteners or with the tool at an overly steep angle as this may cause deflection of fasteners which could cause injury.

Do not drive fasteners close to the edge of the work piece as the wood may split, allowing the fastener to be deflected possibly causing injury.

This nailer produces SPARKS during operation. NEVER use the nailer near flammable substances, gases or vapors including lacquer, paint, benzine, thinner, gasoline, adhesives, mastics, glues or any other material that is -- or the vapors, fumes or byproducts of which are -- flammable, combustible or explosive. Using the nailer in any such environment could cause an EXPLOSION resulting in personal injury or death to user and bystanders.

400 SERIES, 500 SERIES specifications

The Bostitch 500 Series and 400 Series are two lines of pneumatic nailers and staplers renowned for their robust performance and innovative features in the construction and woodworking industries. Designed to enhance efficiency and precision, these tools are ideal for both professional and DIY applications.

The Bostitch 500 Series is known for its versatile functionality and lightweight construction. It includes a range of models that cater to framing, roofing, and finishing tasks. One of its standout features is the integrated tool-free depth adjustment that allows users to easily set the desired nail depth without the need for additional tools. This ensures consistent results across various materials, such as softwood, hardwood, and engineered wood.

Another significant technology present in the 500 Series is the oil-free design, which reduces maintenance time and the risk of oil stains on work surfaces. Additionally, these nailers are equipped with a selectable trigger system that allows users to switch between sequential and bump firing modes. This flexibility enables operators to adapt to different work requirements efficiently.

The 400 Series, on the other hand, is specifically designed for heavy-duty applications, making it perfect for professional contractors. These models feature a more robust build quality and enhanced durability, capable of handling tougher jobs with ease. The 400 Series also boasts a high-capacity magazine that minimizes downtime for reloading, allowing for continuous operation on larger projects.

In terms of technological advancements, the 400 Series incorporates an advanced anti-dry fire mechanism that prevents the tool from firing when there are insufficient fasteners in the magazine. This feature not only protects the work surface but also prolongs the lifespan of the tool. Additionally, the lightweight design ensures that users can maneuver the tool comfortably, reducing fatigue during prolonged use.

Both series feature Bostitch’s signature design elements, including ergonomic handles for better grip and comfort, and a compact profile for easy access in tight spaces. The durable construction of each model ensures that they can withstand the rigors of daily use on the job site.
