TO CHANGE THE TRIGGER (Fig. 7)

WARNING: 

Disconnect the nailer from the air supply and 

remove fasteners from magazine before making adjustments 
to the tool.

1. Remove the o-ring on the side of the trigger pin. It may be easiest to 
use tweezers, a paperclip, or other appropriate tool. Be careful to not 
damage the O-ring.

2. Remove the trigger pin, the trigger and the trigger spring.

3. Swap the trigger switch out for the alternative trigger.

4. Replace the trigger spring, the trigger, the trigger pin and the o-ring.

TYPES OF TRIGGERS

Two different triggers are included with your nailer. Fully understand the characteristics and activation mode of each 
trigger. Choose the suitable trigger that fits the task at hand.

Sequential Trigger (Black Trigger): 

Your nailer is installed with the sequential trigger. With this trigger installed, the safety bracket needs to be activated 
before pulling the trigger in order to drive a fastener. This trigger prevents the nailer from being able to bump fire, 
which means you cannot hold down the trigger and press down on the safety bracket to fire multiple nails in a row.  
This would be the preferred method for safer operation and more detailed and specific nailing jobs.

Contact Trigger (Red Trigger): 

The contact trigger is provided as an accessory. Using this trigger, you can activate the safety bracket and trigger in 
any sequence to drive a fastener. This trigger gives users the opportunity to both bump fire (where the trigger re-
mains engaged and the bumping of the safety bracket shoots nail after nail) and also sequential fire (where the safety 
bracket remains engaged and the repetitive pulling of the trigger shoots nail after nail). Only one of the two safety 
mechanisms (the trigger or the safety bracket) needs to be disengaged between firing multiple nails. This is best for 
larger jobs where speed is more important than precision. However, there is also is a higher chance of misfiring 
when the contact trigger is installed.

WARNING:

 There is a higher chance of misfiring when the contact trigger is installed. Never put your 

finger on the trigger unless you are prepared for operation. Unintended nails can be discharged when the 
trigger is engaged and the safety bracket is pressed by accident. 

PREPARATION AND ADJUSTMENTS

WARNING: 

Before each use, check the nailer, compressed air connections and air lines. If any parts 

are missing or damaged, do not operate this tool until the parts are repaired and replaced. Failure to do 
so could possibly result in a serious personal injury.
