AIR SUPPLYAND CONNECTIONS

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 powersourcefor this tool. NEVER USE OXYGEN,COMBUSTIBLE GASES, OR BOTTLED GASES,AS A POWER SOURCE FOR THISTOOL AS TOOLMAYEXPLODE.

REGULATOR:

A pressure regulator with an operating pressure of 0 - 125 p.s.i. (0 - 8.79 kg/cm2) is required to control the operating 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.

LUBRICATION

Frequent, but not excessive,lubrication is required for best performance. Use BOSTITCH Air ToolLubricant, Mobil Velocite #10,or equivalent.Do not use detergent oil or additivesas these lubricants will causeacceleratedwear to the seals and bumpers in the tool, resulting in poor tool performanceand frequent tool maintenance.Only a few drops of oil at a time is necessary.Toomuch oil will only collectinsidethe tool and will be noticeablein the exhaust cycle.

COLD WEATHER OPERATION:

For coldweatheroperation,nearand belowfreezing,the moisturein the air line mayfreezeand preventtooloperation. We recommend the use of BOSTITCH winter formulaair tool lubricantor permanentantifreeze(ethylene glycol) as a cold weather lubricant.

CAUTION: Do not store tools in a cold weather environment to prevent frost or ice formation on the tools operating valves and mechanisms that could cause tool failure.

NOTE:Some commercial air line drying liquids are harmful to “O”-rings and seals – do not use these low temperature air dryers without checking compatibility.
