Important - You and others working around you can be seriously injured by fastener driving tools if you do not follow the instructions provided on the tool and in the operations manual. Used properly, these tools provide easy, safe and efficient methods for driving nails, staples & rings. Contact Trip - best suited for high volume rapid fastening where exact placement of the fastener is not important. Sequential Trip - best suited when rapid fastening is not needed or when exact fastener placement is important. Trigger Operation - used when the work piece contact is not practical because of the specific operation performed by the stapler in use. Evaluate your application to determine the best trigger. See Safety Information!

Information Regarding Corrosion - Steel staples are made from galvanized wire and not treated after staples are manufactured. As such, the manufacturer does not guarantee or warranty product against corrosion for any specified time. Zinc coatings on nails and staples can help with corrosion. However, high humidity, salt air, acidic wood, industrial gases, installation impact, preservatives and fire retardants containing salts, can break down the Zinc coating and cause fasteners to rust. Harsh conditions may call for special material coating or special fasteners such as aluminum or stainless steel. Wood manufacturers may call for special or high grade galvanized fasteners which if not used void their product warrantees. Always check the wood manufacturers' specifications beforehand to insure full compliance with their requirements.
