Air pressure at the tool must never exceed
120 psi.
Your pneumatic tool comes ready for immediate use and can be installed
by following these steps:
i. SAFETY-All tool operators and their immediate supervisors must
become familiar with the operator safety instructions before operating
the tool. The instructions are on page 2 of this manual.
ii. Included with each tool are one copy of this Safety and Maintenance
manual and one copy of the Tool Schematic. Keep these publications
for future reference.
iii. The plastic cap in the air inlet of the tool must be removed before the
male air fitting is installed. The fitting must be a male pneumatic type
that discharges the air from the tool when the air line is disconnected.
iv. Install a filter/regulator/lubricator unit with a gauge as close as
practical to the tool, preferably within ten feet. Refer to the Air
Systems section of this manual for air hose requirements and lengths.
In general, no other special installation is required.
v. If the operator is working at a bench or table, it is usually best to run
the air line underneath the bench. A small tray under the benchtop can
hold the fastener supply and the tool when not in use.
vi. If this tool does not work when it is first connected, do not try to make
repairs. Call your local service center immediately.

MAINTENANCE
These tools are built for ease of maintenance. A few simple details will
assure trouble-free operation and long tool life. Anyone who uses or
maintains the tool must read the safety and maintenance instructions.
Study the schematic drawing before starting any repairs on the tool.
Air-operated tools must be inspected periodically, and worn or broken
parts must be replaced to keep the tool operating safety and efficiently.
Also the item on the maintenance chart must be checked often.
COLD WEATHER CARE
When temperatures are below freezing, tools should be kept warm
by any convenient, safe method. If this is not possible, the following
procedure should be used to warm up the tool parts.
Reduce the regulated air pressure to 30 psi.
Remove all fasteners from the tool.
Collect an air line and blank fire the tool. The reduced air
pressure will be enough to free-fire the tool. Slow speed operation
tends to warm up the moving parts. Slowing up the piston helps
bumper and the O-rings to become springy.
,
!
CAUTION ,
!
Never free-fire the tool at high pressure.

- 12 -
12
Once the tool is warmed up, readjust the regulator to the proper
working pressure and reload the tool.
Tool operators working outdoors or in unheated areas in
extremely cold temperatures.
Use recommended air tool oil with antifreeze in the lubricator.
MAINTENANCE
Once a week, depending on the amount of tool use, take the tool
apart and wash away any sludge with degreaser cleaner parts to
keep the tool operating efficiently.
,
!
CAUTION ,
!
Never use kerosene or flammable solvents
to clean the tool.
Cleaning air-operated tools with solvents remover the thin coating of
grease applied to the cylinder wall and ”O” rings at the factory. To
replace this coating of grease, use LITHIUM grease or equivalent on
parts.
Open the drain on the air compressor tank to drain any moisture
at least daily in extremely cold or humid weather. A few ounces of
anti-freeze in the tank will keep the air free of frost.
TESTING THE TOOLAFTER SERVICING
After replacing any part or parts, it is important to check the tool
for proper operation. This ensures that the tool was put together
correctly, is safe to use, and will perform the job properly.
Ensure that all hardware is tight.
Ensure that the work contacting element is installed correctly in
relation to the trigger, and that both parts move freely.
Ensure that the magazine is properly attached.
Ensure that the required safety information on the tool is legible.

- 13 -
13
Use only approved fasteners in the tool, and ensure that they are
correct for the application.
Ensure that a male air fitting is securely connected to the tool.
Test the tool by driving fasteners into a workpiece identical to the
tool’s application.
Check the tool for air leaks during testing and for the proper
sequence of operation.
Ensure that all fasteners are driven to the same depth and that the
crown of the fastener is flush with the workpiece.
MAINTENANCE
TOOL LUBRICATION
It is most important that the tool be properly lubricated by keeping
the air line lubricator filled and correctly adjusted. Without proper
lubrication the tool will not work properly and parts will wear
prematurely.
Use the proper lubricant in the air line lubricator. The lubricator
should be of the low air flow or changing air flow type, and should
be kept filled to the correct level. Use only recommended lubricants.
Substitutes may harm the rubber compounds in the tool “O” rings
and other rubber parts.
If a filter/regulator/lubricator is not installed on the air system,
air-operated tools should be lubricated at least once a day with 6 to
20 drops of oil, depending on the work environment, directly
through the male air fitting in the tool housing.
Most minor problems can be resolved quickly and easily using the
maintenance table that follows. If problems persist, contact your
local dealer for assistance.
