MAINTENANCE
Duo-Fast
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 sche-
matic 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
safely and efficiently. Also the items 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 tools.
❑
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 the bumper and the O-rings
to become springy.
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 should also:
Use pneumatic oil with antifreeze in the
lubricator, Part No. 219090 (8oz.)
Once a week, depending on the amount of tool
use, take the tool apart and wash away any sludge
with degreaser cleaner (Part No. 902330) to keep the
tool operating efficiently.
Cleaning the air-operated tools with solvents removes the
thin coating of grease applied to the cylinder wall and
O-rings at the factory. To replace this coating of grease,
use Chemplex grease (Part No. 403734).
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 Tool After 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.
❑
Use only Duo-Fast 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.
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 lu-
bricator should be of low air flow or changing air flow type,
and should be kept filled to the correct level. Use only
Duo-Fast recommended lubricants. Substitutes may harm
the rubber compounds in the tool's O-rings and other rub-
ber parts. Part No. 403720 is a pneumatic lubricating oil
specially made for pneumatic applications. If a filter/regu-
lator/lubricator is not installed on the air system, air oper-
ated 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 fitting in the tool housing.
Most minor problems can be resolved quickly and eaily
using the maintenance table that follows. If problems per-
sist, contact your Duo-Fast dealer for assistance.
