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. This tool is equipped with an internal filter.
To maintain proper air flow the filter must be cleaned regularly. To clean the filter, remove the filter from the end cap and
use compressed air from a blow gun to blow the dirt from the filter.
An in-line 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 Tool Lubricant, PREMOIL-
4oz, or equivalent. Do not use detergent oil or additives as these lubricants will cause accelerated wear to the seals
and bumpers in the tool, resulting in poor tool performance and frequent tool maintenance. Only a few drops of oil at
a time is necessary. Too much oil will only collect inside the tool and will be noticeable in the exhaust cycle.
COLD WEATHER OPERATION:
For cold weather operation, near and below freezing, the moisture in the air line may freeze and prevent tool
operation. We recommend the use of Bostitch winter formula air tool lubricant, WINTEROIL-4oz, or permanent
antifreeze (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.
LOADING THE TOOL
EYE PROTECTION which conforms to ANSI specifications and provides protection against
flying particles both from the FRONT and SIDE should ALWAYS be worn by the operator
and others in the work area when connecting to air supply, loading, operating or servicing
this tool. Eye protection is required to guard against flying fasteners and debris, which
could cause severe eye injury.
The employer and/or user must ensure that proper eye protection is worn. Eye protection
equipment must conform to the requirements of the American National Standards Institute,
ANSI Z87.1 and provide both frontal and side protection. NOTE: Non-side shielded spectacles
and face shields alone do not provide adequate protection.
TO PREVENT ACCIDENTAL INJURIES:
• Never place a hand or any other part of the body in nail discharge area of tool while the air supply
is connected.
• Never point the tool at anyone else.
• Never engage in horseplay.
• Never pull the trigger unless nose is directed at the work.
• Always handle the tool with care.
• Do not pull the trigger or depress the trip mechanism while loading the tool.
NOTE: Use only nails recommended for use in Bostitch Framing nailers or nails which meet the Bostitch
specifications.
