Dewalt DWMIIIFS Instruction Manual - Page 5

Operating Pressure 70 to 90 p.s.i.g. (4.9 to 6.3 kg/cm2). Select the operating pressure within this range for best fastener performance. DO NOT EXCEED THIS RECOMMENDED OPERATING PRESSURE. Air Consumption The DWMIIIFS requires 4.2 cubic feet per minute (221 liters per minute) of free air to operate at the rate of 60 fasteners per minute, at 80 p.s.i. (5.6 kg/cm2). Take the actual rate at which the tool will be run to determine the amount of air required. For instance, if your fastener usage averages 30 fasteners per minute, you need 50% of the tool's c.f.m. of free air which is required to operate the tool at 60 fasteners per minute. OPERATION Air Supply and Connections WARNING: Do not use oxygen, combustible gases, or bottled gases as a power source for this tool as tool may explode, possibly causing injury. FITTINGS Install a male plug on the tool which is free flowing and which will release air pressure from the tool when disconnected from the supply source. HOSES Air hoses should have a minimum of 150 p.s.i. (10.6 kg/cm2) working pressure rating or 150 percent of the maximum pressure that could be produced in the air system. The supply hose should contain a fitting that will provide "quick disconnecting" from the male plug on the tool. SUPPLY SOURCE Use only clean regulated compressed air as a power source for this tool. NEVER USE OXYGEN, COMBUSTIBLE GASES, OR BOTTLED GASES, AS A POWER SOURCE FOR THIS TOOL AS TOOL MAY EXPLODE. REGULATOR A pressure regulator with an operating pressure of 0 - 125 p.s.i. (0 - 8.79 kg/cm2) is required to control the operati­ing pressure for safe operation of this tool. Do not connect this tool to air pressure which can potentially exceed 200 p.s.i. (14 kg/cm2) as tool may fracture or burst, possibly causing injury. OPERATING PRESSURE Do not exceed recommended maximum operating pressure as tool wear will be greatly increased. The air supply must be capable of maintaining the operating pressure at the tool. Pressure drops in the air supply can reduce the tool's driving power. Refer to Tool Specifications for setting the correct operating pressure for the tool. FILTER Dirt and water in the air supply are major causes of wear in pneumatic tools. A filter will help to get the best performance and minimum wear from the tool. The filter must have adequate flow capacity for the specific installation. The filter has to be kept clean to be effective in providing clean compressed air to the tool. Consult the manufacturer's instructions on proper maintenance of your filter. A dirty and clogged filter will cause a pressure drop which will reduce the tool's performance. 5- ENG
