Select a compressor that has ample pressure and air output to assure cost-efficient operation. The graph shows the relation between nailing frequency and compressor air output at a compression of 8.5 kgf/cm.G (120 PSIG). Thus, for example, when you drive about 10 nails 3.75 mm x 90 mm (0.148” x 3-1/2”) per minute, a compressor with an air output over 55 l/minute is required. Pressure regulators must be used to limit air pressure to the rated pressure of the tool where air supply pressure exceeds the tool’s rated pressure. Failure to do so may result in serious injury to tool operator or persons in the vicinity. NOTE: • Nail size indicates diameter x length. Selecting air hose Use an air hose as large and as short as possible to assure continuous, efficient nailing operation. With an air pressure of 5 kgf/cm.G (70 PSIG), an air hose with an internal diameter of over 8.5 mm (5/16”) and a length of less than 20 m (6.6 ft.) is recommended when the interval between each nailing is 0.5 seconds. Air supply hoses shall have a minimum working pressure rating of 10.7 kgf/cm.G (150 PSIG) or 150 percent of the maximum pressure produced in the system whichever is higher. CAUTION: Low air output of the compressor, or a long or smaller diameter air hose in relation to the nailing frequency may cause a decrease in the driving capability of the tool. Nail guide D1 D2 Gauge Lubrication To insure maximum performance, install an air set (oiler, regulator, air filter) as close as possible to the tool. Adjust the oiler so that one drop of oil will be provided for every 20 nails. When an air set is not used, oil the tool with pneumatic tool oil by placing 2 (two) or 3 (three) drops into the air fitting. This should be done before and after use. For proper lubrication, the tool must be fired a couple of times after pneumatic tool oil is introduced. Selecting nails CAUTION: • Do not drive hardened steel nails or stainless steel nails into concrete or steel plate. If you do so, the nailer may be adversely affected. Always check the size of the nail head with the gauge on the nail guide before loading the nailer. Different size nails may be mixed up in the nails you purchase locally. Do not use nails with a head size larger than D1 or smaller than D2.Nails withaheadsizelargerthanD1cannot be inserted into the nail guide. Nails with a head size smaller than D2 may move into the contact arm and cannot be driven. • • • Nail head Nail shank Nail tip Nail Magnet Nail guide Contact arm Adjuster • • • Nail head Nail shank Nail tip Nail Magnet Nail guide Contact arm Adjuster Loading nailer CAUTION: Be careful not to touch the trigger when loading the nail. When loading nail into the nailer, grip the nail by the shank, not the tip. Hold the nail shank lightly and insert the nail head into the nail guide until the nail is held firmly by the magnet. Adjusting depth of nailing CAUTION: Always disconnect the hose before adjusting the depth of nailing. To adjust the depth of nailing, turn the adjuster so that the arrow above the adjuster will point to the number indicated on the adjuster. The depth of nailing is the deepest when the arrow points to the number 1. It will become shallower as the arrow points to higher number. The depth can be changed in approx. 1.5 mm (1/16”) increments per graduation. If nails cannot be driven deep enough even when the arrow points to the number 1, increase the air pressure. Connecting air hose Slip the air socket of the air hose onto the air fitting on the nailer. Be sure that the air socket locks firmly into position when installed onto the air fitting. A hose coupling must be installed on or near the tool in such a way that the pressure reservoir will discharge at the time the air supply coupling is disconnected.

To start driving, place the tip of the nail against the driving surface and pull the trigger. At the start of driving, apply gentle downward pressure on the nailer in the arrow direction to hold the nail firmly. When the impact of the contact arm stops, the driving operation is over. If the nail is not driven deep enough, place the ejection port of the nailer over the nail head. Press the nailer against the driving surface firmly and pull the trigger to do additional driving of the nail. NOTE: • The nailer will not operate unless you apply sufficient pressure to the contact arm. If this occurs, apply forward pressure to the nailer again while pulling the trigger to start operation.
