Adjustin g Th e Di rection of the Exhaust The CHN70900 is equipped with an adjustable direction exhaust deflector. This is intended to allow the user to change the direction of the exhaust. Simply twist the deflector to any direction desired.

Disconnect air supply from nailer. 2. Remove no-mar tip from storage post. 3. Remove retaining ring from no-mar tip. 4. Carefully place no-mar tip over the end of work contact element. Position tip onto WCE making certain serrated gooves on each piece are in line and fit snugly together. 5. Position retaining ring on no-mar tip and press firmly in place. 6. Check that the WCE and trigger move up and down freely without sticking or binding. reMovINg No-Mar tIP 1. Disconnect air supply from nailer. 2. Remove no-mar tip retaining ring. 3. Pry no-mar tip away from the work contact element. 4. Replace retaining ring onto no-mar tip, then store tip on storage post for future use. 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 on the “ ” side to activate Sequential Mode. Press the conversion switch on 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 bydepressingtheWorkContactElement(WCE)againstworksurface followedby 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 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.

Work Surface Figure 17 - sequential Mode 12 Operating Instructions and Parts Manual CHN70900 Pre-Operation (Continued) 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. MakesurethetriggerandWorkContactElement(WCE)movefreelyupanddown 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...
