Do not attempt to carve or engrave on the tool. 27. Stop nailing operations immediately if you notice something wrong or out of the ordinary with the tool. 28. Always disconnect the air hose and remove all of the nails: (1) When unattended. (2) Before performing any maintenance or repair. (3) Before cleaning a jam. (4) Before moving the tool to a new location. 29. Perform cleaning and maintenance right after finishing the job. Keep the tool in tip-top condition. Lubricate moving parts to prevent rusting and minimize friction-related wear. Wipe off all dust from the parts. 30. Do not modify tool without authorization from Makita. 31. Do not attempt to keep the trigger or contact element depressed with tape or wire. Death or serious injury may occur. 32. Always check contact element as instructed in this manual. Nails may be driven accidentally if the safety mechanism is not working correctly. 33. Ask Makita’s Authorized service centers for periodical inspection of the tool. 34. To maintain product SAFETY and RELIABILITY, maintenance and repairs should be performed by Makita Authorized or Factory Service Centers, always using Makita replacement parts. SAVE THESE INSTRUCTIONS. WARNING: MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury. 3 SYMBOLS SYMBOLS 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 007305 Compressor air output per minute CFM 3 (ft /min.) 3 2 1 0 Nailing frequency (times/min.) 10 20 30 40 50 60 8.0kgf/cm G(115PSIG)27.0kgf/cm G(100PSIG)2 6.0kgf/cm G(85PSIG)2 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 60 times per minute at a compression of 7.0 kgf/cm2G (100 PSIG), a compressor with an air output over 2 CFM ( 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. 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 6.5 mm (1/4”) 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 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 50 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. 007180 1. Pneumatic tool oil 4 FUNCTIONAL DESCRIPTION FUNCTIONAL DESCRIPTION CAUTION: • Always disconnect the hose before adjusting or checking function on the tool. Adjusting depth of nailing 007181 1 A B 1. Adjuster To adjust the depth of nailing, turn the adjuster. The depth of nailing is the deepest when the adjuster is turned fully in the A direction shown in the figure. It will become shallower as the adjuster is turned in the B direction. If nails cannot be driven deep enough even when the adjuster is turned fully in the A direction, increase the air pressure. If nails are driven too deep even when the adjuster is turned fully in the B direction, decrease the air pressure. Generally speaking, the tool service life will be longer when the tool is used with lower air pressure and the adjuster set to a lower depth of nail driving. CAUTION: • Always disconnect the hose before adjusting the depth of nailing. Hook 007182 1 1. Hook CAUTION: • Always disconnect the hose from the tool. • Never hook the tool at high location or on potentially unstable surface. The hook is convenient for hanging the tool temporarily. ASSEMBLY CAUTION: • Always disconnect the hose before carrying out any work on the tool. • Load the same kind,...
