SYMBOLS USD501-1 The followings show the symbols used for tool. Read and understand tool labels and manual. Operators and others in work area must wear safety glasses with side shields. Keep fingers away from trigger when not driving fasteners to avoid accidental firing. INSTALLATION Selecting compressor 005686 Compressor air output per minute 6.0kgf/c 7m.8.20G5(kk8gf5g/fP/cScImmG2)G2(G1(0102P0SPISGI)G) (ft 3/min.) 4 3 2 G(65PSIG) 2 4.5kgf/cm 1 Selecting air hose 004294 Use an air hose as large and as short as possible to assure continuous, efficient nailing operation. With an air pressure of 5.0 kgf/cm2G (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/cm2G (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. Lubrication 004295 0 10 20 30 40 50 60 Nailing frequency (times/min) The air compressor must comply with the requirements of ANSI B19.3. Select a compressor that has ample pressure and air output to assure cost-efficient operation. The graph shows the relation between nailing frequency, applicable pressure and compressor air output. Thus, for example, if nailing takes place at a rate of approximately 40 times per minute at a compression of 6.0 kgf/cm2G (85 PSIG), a compressor with an air output over 3 ft3/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. 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 30 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. 007005 1. Pneumatic tool 1 oil 4
