Trigger pull force adjustment, Pump lever adjustment – Daisy AVANTI Triumph 747 User Manual
TRIGGER PULL FORCE ADJUSTMENT
Trigger pull force can be adjusted between
approximately one and three pounds force. To
increase the trigger pull force, turn the trigger
adjusting screw (Fig. 6) clockwise. To decrease the
trigger pull force, turn the screw counterclockwise.
Stops are provided at the end of the adjustment.
WARNING: When the trigger adjusted to less
than 2 lbf, the gun may fire if dropped.
PUMP LEVER ADJUSTMENT
IMPORTANT: After 500 shots, and every 1,000 shots thereafter, the length of the pump
lever stroke may need adjustment in order to maintain maximum performance. To check
and make the needed adjustments, follow these steps:
Step 1. After firing the gun, open the pump lever and close to the point where a slight
resistance can be felt and stop.
Step 2. Measure the distance between the receiver and end of the pump lever as shown
in Figure 7. This dimension should be between 1 1/8 and 1 1/2 inches. If the
clearance dimension on your gun is within this range, no adjustment is required.
If the clearance dimension is not within this range, proceed to Step 3.
Step 3. With the pump lever in the fully open position, place a screwdriver with a large
blade between slots in the threaded portion of the pump. (Fig. 8) To increase the
pump lever clearance, rotate the screwdriver clockwise. To decrease the pump
lever clearance, rotate the screwdriver counterclockwise.
NOTE: Adjusting the pump lever to a clearance dimension larger than 1 1/2 inches
will overstress the gun and will result in permanent damage to the gun. Maximum
performance will be achieved by adjusting the clearance as specified in Step 2.
