Pre-Operation
oPeratIoNal Modes
Always know the operational mode of the nailer before using. Failure to
know the operational mode could result in death or serious injury.
This nailer may be operated in the “Sequential” mode (as supplied by the
manufacturer) or “Bump” mode. the tool may be converted from one mode to the other
by firmly pressing the conversion switch from one position to the other.
Press the conversion switch to the “ ” side to activate Sequential Mode.
Press the conversion switch to the “ ” side to activate Bump Mode.
Press either side to the middle position to activate the Safety Lockout Mode.
sequential Mode
This method is recommended when precise nail placement is required. Operation in
this mode requires trigger to be pulled each time a nail is driven. Nailer can be actuated
by depressing the Work Contact Element (WCE) against work surface followed by
pulling the trigger.
The trigger must be released after each fastener is driven to allow tool to reset.
Since the tool can only be actuated by first removing the finger from the trigger, this
is considered to be a more restrictive mode of operation, suitable for less experienced
users.
Bump Mode
This method is recommended when less precise nail placement is required. Operation
in this mode requires trigger to be depressed with nailer off of the work surface. Then,
the nose of the nailer is tapped against the work surface causing a nail to be driven.
Each time the Work Contact Element is depressed, a nail is driven into the work
surface. Extreme care should be taken because a nail will be driven when the WCE is
pressed against any surface.
Since the tool can be actuated without removing the finger from the trigger, this is
considered to be a less restrictive mode, suitable for more experienced users.
safety lockout Mode
When the conversion switch is pressed into the middle position, the trigger is in Safety
Lockout Mode. In this mode, no combination of WCE and trigger activations will allow
the tool to cycle or fire. If tool does operate while in Safety Lockout Mode, contact
Campbell Hausfeld for technical support, and do not use the nailer until repaired.
Work CoNtaCt eleMeNt (WCe)
Check the operation of the Work Contact Element (WCE) trip mechanism
before each use. The WCE must move freely without binding through its
entire travel distance. The WCE spring must return the WCE to its fully extended position after
being depressed. Do not operate the nailer if the WCE trip mechanism is not operating properly.
Personal injury may occur.
1. Disconnect the air supply from the nailer.
2. Make sure the trigger and Work Contact Element (WCE) move freely up and down
without sticking or binding.
NOTE: If the tool is not loaded with nails, the anti-dry fire feature will not allow the
WCE to be depressed.
3. Reconnect air supply to the nailer.
4. Use a scrap piece of wood as a work surface.
