MAINTAINING THE PNEUMATIC TOOL

When working on air tools, note the warnings in this manual and use extra care evaluating problem tools.

CAUTION: Pusher spring (constant force spring). Caution must be used when working with the spring assembly. The spring is wrapped around, but not attached to, a roller. If the spring is extended beyond its length, the end will come off the roller and the spring will roll up with a snap, with a chance of pinching your hand. Also the edges of the spring are very thin and could cut. Care must also be taken to insure no permanent kinks are put in the spring as this will reduce the springs force.

REPLACEMENT PARTS:

BOSTITCH replacement parts are recommended. Do not use modified parts or parts which will not give equivalent performance to the original equipment.

ASSEMBLY PROCEDURE FOR SEALS:

When repairing a tool, make sure the internal parts are clean and lubricated. Use Parker “O”-LUBE or equivalent on all “O”-rings. Coat each “O”-ring with “O”-LUBE before assembling. Use a small amount of oil on all moving surfaces and pivots. After reassembly add a few drops of BOSTITCH Air Tool Lubricant through the air line fitting before testing.

AIR SUPPLY-PRESSURE AND VOLUME:

Air volume is as important as air pressure. The air volume supplied to the tool may be inadequate because of undersize fittings and hoses, or from the effects of dirt and water in the system. Restricted air flow will prevent the tool from receiving an adequate volume of air, even though the pressure reading is high. The results will be slow operation, misfeeds or reduced driving power. Before evaluating tool problems for these symptoms, trace the air supply from the tool to the supply source for restrictive connectors, swivel fittings, low points containing water and anything else that would prevent full volume flow of air to the tool.

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.

In summary, the Bostitch 500 Series and 400 Series offer a blend of cutting-edge technology, user-friendly features, and durable construction, making them essential tools for professionals and enthusiasts alike. With their efficient performance and innovative designs, these nailers and staplers continue to set the standard in the industry.
