 ALWAYS USE SAFETY GLASSES. Everyday eyeglasses are NOT safety 

glasses. Also use face or dust mask if operation is dusty. ALWAYS WEAR CERTIFIED SAFETY 
EQUIPMENT:

•  ANSI Z87.1 eye protection (CAN/CSA Z94.3),
•  ANSI S12.6 (S3.19) hearing protection,
•  NIOSH/OSHA respiratory protection.

Before operating this tool, carefully read and understand all instructions in Important 
Safety Instructions.

 Keep fingers AWAY from trigger when not driving fasteners to avoid accidental 

firing. Never carry tool with finger on trigger. In bump action mode (contact actuation mode) 
tool will fire a fastener if safety is bumped while trigger is depressed. 

 In accordance with the ANSI Standard SNT-101-2002, the PORTER-CABLE nailers are 
assembled with a sequential action trigger. For a replacement trigger contact your authorized 
service center or call 1-888-848-5175.
The red trigger with 

 imprinted on the side, (Cat.# 600852 kit) is the single sequential action 

trigger and causes the tool to operate in this mode.
The black trigger with 

 imprinted on the side, (Cat.# 600851 kit) is the bump action trigger 

and permits the tool to be actuated in this manner.
For defining the use of the sequential action trigger and bump action trigger, see the 
Actuating Tool section of this manual.

at the beginning of this manual. Always wear eye and ear protection when operating this 
tool. Keep the nailer pointed away from yourself and others. For safe operation, complete the 
following procedures and checks before each use of the nailer. 

NOTE: These nailers are designed to be used without oil. 
1.  Before you use the nailer, be sure that the compressor tanks have been properly drained.
2.  Wear proper eye, hearing and respiratory protection.
3.  Remove all fasteners from the magazine. 
4.  Check for smooth and proper operation of contact trip and pusher assemblies. Do not 

use tool if either assembly is not functioning properly. NEVER use a tool that has the 
contact trip restrained in the up position.

5.  Check air supply. Ensure that air pressure does not exceed recommended operating 

limits; 70 to 120 psi, (4.9 to 8.3 bar, 5 to 8.5 kg/cm

2

).

6.  Connect air hose.
7.  Check for audible leaks around valves and gaskets. Never use a tool that leaks or has 

damaged parts. 

 To reduce the risk of injury, ALWAYS wear proper eye [ANSI Z87.1 (CAN/CSA 

Z94.3)] and hearing protection [ANSI S12.6 (S3.19)] when operating this tool.

Do not keep trigger depressed when tool is not in use. Keep the lock-off 

switch rotated to the right (OFF) when the tool is not in use. Serious personal injury may result.

Each PORTER-CABLE nailer is equipped with a trigger lock-off switch (A) which when rotated 
to the right, prevents the tool from actuating. When the switch is centered, the tool will be fully 
operational. The trigger should always be locked off whenever any adjustments are made or 
when tool is not in use.

 

Keep the tool pointed away from yourself and others. Serious personal injury 

may result.

 Never load nails with the contact trip or trigger activated. Personal injury may 

result.

The PORTER-CABLE finish nailers are equipped with load and lock magazines. 

Load and Lock Method (Fig. 5)
1.  Lock off trigger.
2.  Insert fasteners into the rear of the magazine (E).
3.  Pull pusher (G) back until the nail follower falls behind the nails.

To reduce the risk of injury, ALWAYS wear proper eye [ANSI Z87.1 (CAN/CSA 

Z94.3)] and hearing protection [ANSI S12.6 (S3.19)] when operating this tool.

The tool can be actuated using one of two modes: single sequential action trigger mode and 
bump action trigger mode. The trigger installed on the tool as described in the Trigger section 
of this manual determines the mode of operation. 

Sequential Action Trigger - 

 (red)

The sequential action trigger’s intended use is for intermittent nailing where very careful and 
accurate placement is desired.
To operate the nailer in sequential action mode:
1.  Depress the contact trip firmly against the work surface.
2.  Depress the trigger.

 A nail will fire each time the trigger is depressed as long as the contact trip 

remains depressed.

Bump Action Trigger - 

 (black)

The bump action trigger’s intended use is for rapid nailing on flat, stationary surfaces. 
Using the bump action trigger, two methods are available: place actuation and bump 
actuation.
To operate the tool using the PLACE ACTUATION method:
1.  Depress the contact trip against the work surface.
2.  Depress the trigger.
To operate the tool using the BUMP ACTUATION method:
1.  Depress the trigger.
2.  Push the contact trip against the work surface. As long as the trigger is depressed, the 

tool will fire a nail every time the contact trip is depressed. This allows the user to drive 
multiple nails in sequence.

 Do not keep trigger depressed when tool is not in use. Keep the lock-off 

switch rotated to the right (OFF) when the tool is not in use.

•  Lock OFF trigger.
•  Disconnect air supply.
•  Avoid contact with trigger during adjustments.

The depth that the fastener is driven can be adjusted using the depth adjustment next to the 
trigger of the tool.
1.  To drive the nail shallower, rotate the depth setting wheel (F) to the right.
2.  To drive a nail deeper, rotate the depth setting wheel (F) to the left.

•  verrouiller la détente;
•  débrancher la source d’alimentation en air;
•  éviter tout contact avec la détente lors des réglages.

  Les scies, meules, ponceuses, perceuses ou autres outils de 

construction peuvent produire des poussières contenant des produits chimiques reconnus 
par l’État californien pour causer cancers, malformations congénitales ou être nocifs au 
système reproducteur. Parmi ces produits chimiques, on retrouve :

•  le plomb dans les peintures à base de plomb ;
•  la silice cristallisée dans les briques et le ciment ou autres articles de maçonnerie ; et 
•  l’arsenic et le chrome dans le bois ayant subi un traitement chimique.

Le risque associé à de telles expositions varie selon la fréquence à laquelle on effectue ces 
travaux. Pour réduire toute exposition à ces produits : travailler dans un endroit bien aéré, en 
utilisant du matériel de sécurité homologué tel un masque antipoussières spécialement conçu 
pour filtrer les particules microscopiques.
