Air supply and connections (con't.)

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 that will reduce the 
tool's performance.

Lubrication

Frequent lubrication is required for best performance.  Oil added through the air line
connection will lubricate the internal parts.  Use a good quality air tool oil.  Do not use
detergent oil or additives as these will cause accelerated wear to the seals and bumpers
in the tool, resulting in poor performance and frequent need for maintenance.
If an inline oiler is not used, add oil during use into the air fitting on the tool once or twice
a day.  Only a few drops at a time are necessary.  Too much oil will 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 a winter formula air tool
lubricant.
Caution: Do not store tools in a cold environment to prevent frost or ice formation on the

tool's 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 Floor Nailer

To prevent accidental injuries:
· Always wear ANSI approved eye protection
· Never place a hand or any other body part in nail discharge area of the tool while the
air supply is connected
· Never point the tool at other people
· 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

Staple loading

Pull cover open.  Insert stick of staples.  Push cover forward until the detent pin snaps 
into place, locking the cover.  The tool is now ready to operate.

Tool operation

· Floor nailer is actuated (fired) by hitting the cap firmly with a mallet (not included).
· Always wear ANSI approved eye protection.
· Never use this tool in a manner that could cause a fastener to be directed toward the
user or others in the work area.
· Do not use the tool as a hammer to position flooring strips, as this could damage the
tool.  Use the mallet for this purpose instead.
· Always carry the tool by the handle.  Never carry the tool by the air hose.
· Do not alter or modify this tool from the original design or function.
