Bump Mode
This method is recommended when less precise nail placement is required. Operation in this mode requires the 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
3.Reconnect air supply to the nailer.
4.Use a scrap piece of wood as a work surface.
5.Depress the WCE against the work surface without pulling the trigger (See Figure 18). The nailer must not operate. Do not use the tool if it operates without pulling the trigger. Personal injury may result.
6.Remove nailer from work surface. The WCE must return to its original down position. Pull the trigger (See Figure 19). The nailer must not operate. Do not use the tool if it operates while lifted from the work surface. Personal injury may result.
7.Pull the trigger and depress the WCE against the work surface. The nailer MUST operate when in bump mode. The nailer MUST NOT operate if in sequential mode.
8.Depress the WCE against work surface. Pull the trigger. The nailer MUST operate.
9.Switch nailer into the other Mode as described in Operational Modes section and repeat.
IMPORTANT: Repeat steps one through nine with tool in Safety Lockout Mode. Tool should not operate at any step. If tool does operate while in Safety Lockout Mode, contact Campbell Hausfeld for technical support.
Electronics ON / OFF Switch
Located on the battery compartment is an ON/ OFF for the tool’s electronic functions, low nail indicator LEDs, and nail placement laser (See Figure 20).
To utilize the function, turn the battery switch to the “ON” position. To avoid unwanted battery depletion during storage, turn the switch to the “OFF” position.
Pull trigger first...
