User manual MAKITA AN621(1)

[. . . ] Do not actuate the tool unless the tool is placed firmly against the workpiece. Do not load the tool with fasteners when any one of the operating controls is activated. Do not operate the tool with any power source other than that specified in the tool operatingkafety instructions. An improperly functioning tool must not be used. Sparks sometimes fly when the tool is used. [. . . ] Be sure that dust, sand, chips and foreign matter will not enter the tool in the place where you leave It setting. Do not point the ejection port at anyone in the vicinity. Keep hands and feet away from the ejection port area. *When the air hose is connected, do not carry the tool with your finger on the trigger or hand it to someone In this condition. Accidental firing can be extremely dangerous. Handle the tool carefully as there is high pressure inside the tool that can be dangerous if a crack Is caused by rough handling (dropping or striking). Do not attempt to carve or engrave on the tool. 8 Stop nailing operations immediately if you notice something wrong or out of the ordinary with the tool. Always disconnect the air hose and remove all of the nails: 1. Before moving the tool to a new location. * I I Perform cleaning and maintenance right after finishing the job. Lubricate moving parts to prevent rusting and minimize friction related wear. Wipe off all dust from the parts. When not operating the tool, always lock the trigger by turning the change lever to the LOCK position. 9 Do not operate this tool if it does not contain a legible WARNING LABEL. I I Do not modify tool without authorization from Makita. Ask Makita's Factory or Authorized service center for periodical inspection of the tool. 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. r------ 10 TOOL INSTALLATION INSTRUCTIONS AND US Selecting compressor The air compressor must comply with the requirements of ANSI 819. 3 - 1981. 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 0. 49 MPa (70 PSIG). 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 Use an air hose as large and as short as possible to assure continuous, efficient nailing operation. With an air pressure of 0. 49 MPa (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 1. 06 MPa (150 PSIG) or 150 percent of the maximum pressure produced in the system whichever is higher. I 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. 24 c . - E 8 a . -3 a a2 m b tl 5 00 ii 10 20 30 40 Nailing frequency 50 60 (timeshnin Lubrication T insure maximum performance, install an air set o (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. For proper lubrication, the tool must be fired a couple of times after pneumatic tool oil is introduced.

Plastic collated coil Loading nailer CAUTION: *Always lock the trigger and disconnect the hose before loading the nailer. Pull the lever of the magazine cap and open the magazine cap. L Lift and turn the coil support plate to set it to the graduations of the magazine. [. . . ] Failure to maintain sufficient lubrication will cause O-rings to wear quickly. Keep the air hose away from heat (over 6OoC, over 14OOF), away from chemicals (thinner, strong acids or alkalis). Also, route the hose away from obstacles which it may become dangerously caught on during operation. Hoses must also be directed away from sharp edges and areas which may lead to damage or abrasion to the hose. T maintain product SAFETY and RELIABILITY, maintenance and repairs should be performed by Makita o Authorized or Factory Service Centers, always using Makita replacement parts. 18 !
