UNDERSTANDING TOOL CYCLING SYSTEMS
1. Check the cycle information label to determine what system is installed on the tool. You should understand
the actuation system on your tool prior to use, and ensure that it is the most appropriate system for your use.
2. DUO-FAST has 6 systems. All are not available for every tool type. See your DUO-FAST Sales Service Center
for details on these options.
3. The 6 systems are:
• FULL SEQUENTIAL CYCLE (BLUE LABEL) - To actuate the tool, the work contact element must be
activated first, then the trigger. This sequence must be repeated for every actuation.
• SEQUENTIAL CYCLE (GREEN LABEL) - To actuate the tool, the work contact element must be activated
first, then the trigger. The trigger can be released and re-activated to continuously actuate the tool as
long as the work contact element is held activated.
• DUAL TRIGGER CYCLE (GRAY LABEL) - To actuate the tool, place tool on work piece where you want to
drive fastener, depress rear trigger, then depress front trigger. NOTE: Tool WILL actuate if force is applied
to both triggers in any sequence.
• STANDARD CYCLE (BLACK LABEL) - To actuate the tool, two (2) methods can be used:
Trigger Trip - As in the sequential cycle system the work contact element is activated first. Then
the trigger can be repeatedly activated for multiple actuations.
Touch Trip - The trigger is activated first, and then the work contact element can be repeatedly
activated for multiple actuations.
• WARNING RAPID CYCLE (ORANGE LABEL) - The tool has been modified to operate as a standard cycle
tool, but at a much faster rate. This type of tool is intended only for experienced operators.
• DANGER AUTO CYCLE (RED LABEL) - The tool has been modified to cycle continuously when both the
trigger and work contact element are activated. The tool will auto-cycle when actuated either trigger or
work contact element first. This type of tool is intended for a special application by experienced
operators only.
CAUTION: A sequential actuation system may reduce the risk of personal injury by eliminating the ability to
"touch trip" the tool (activating the work contact element while holding the trigger depressed). With a
sequential actuation system you will not accidentally discharge a fastener if you bump the work contact element
against yourself or a co-worker while the trigger is depressed. The sequential actuation systems are typically
preferred where precision of fastener location is more important than speed of operation or where sequential
actuation does not impact your intended use of the tool.
OPERATING AIR PRESSURE
FILTER/ REGULATOR/ PRESSURE GAUGE/ LUBRICATOR
• The correct operating air pressure is the lowest that will do the job. Using the
tool at a higher air pressure than required wastes air, and can cause the tool to
generate higher noise level than necessary. Protect your hearing. Start at 80 PSIG
and adjust the air pressure up or down as required. OPERATING AIR PRESSURE MUST
NOT EXCEED THE MAXIMUM PRESSURE RATING FOR THE TOOL.
•Never Use: High pressure bottle or cylinder, flammable gases or any air source that
exceeds 200 PSIG.
EXPLOSION WILL OCCUR.
• A filter, pressure regulator and lubricator should be included in the air
system for proper tool operation.
• FILTER: A filter will prevent excessive wear and part corrosion by trapping
pipe scale, dirt, solidified lubricants, oil, moisture and other components.
Moisture removal prevents frozen air lines when operating at low
temperatures.
• REGULATOR: The most important requirement for proper tool operation is
the correct air pressure for the job. If the tool is overpowered, tool wear is
increased. If the tool is under-powered, it will not perform satisfactorily. A
regulator, positioned close to the tool, assures proper and economical tool
operation.
PRESSURE GAUGE: The use of the pressure gauge is very important, as
it indicates the air pressure at which the tool is operating.
• LUBRICATOR: The heavy-duty lubricants used in routine maintenance will
not remain in the tool indefinitely. A line lubricator that injects an oil mist
into the tool's air supply is essential. Refer to "Air Line Lubricants" for type
of lubricants to use.
