Carlisle ST1 Trigger Lock Knob 336737

The Carlisle ST1 is a spray foam gun that requires periodic maintenance to ensure optimal performance. One of the maintenance tasks is to adjust the trigger lock knob on the tool, which is a small screw that controls the tension of the trigger. The trigger lock knob has the part number 336737 and can be found on the back of the gun, near the handle. The trigger lock knob can be tightened or loosened by using a hex key, depending on the user’s preference. The trigger lock knob allows the user to lock the trigger in the open position, which can reduce fatigue and improve efficiency when spraying large areas. The trigger lock knob is included in the ST1 complete o-ring kit, which contains all the necessary o-rings and side seals for the ST1 gun.
