Operating Instructions and Parts Manual
www.chpower.com
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.
5. Depress the WCE against the work surface without pulling the trigger (See
Figure 19). 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 20). 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.
