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 6. 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. 7) 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.

PROPER CARE AND MAINTENANCE
To maintain top shooting performance, lightly oil the three pump lever hinges and pump
oil wiper on the pump rod every 1,000 shots (Fig. 8). Excessive oil on the wiper will affect
accuracy. When a finger is pressed against the wiper, only a light trace of oil should be
deposited on the finger. Excess oil on the wiper will migrate into the pump system and
can affect accuracy from heavy oil deposits in the barrel. Use only a 20-weight non-
detergent automotive motor oil. Other type oils may ruin the seals. The exterior is cleaned
by wiping with a soft, clean cloth. The screws and rear sight should be wiped with oil to
prevent rust.
