maintain proper tension on the springs within the assembly. It must be
removed prior to use if the Insert Slide Clamp option is enabled.
1. Open the pump door. See Figure 2-2 for the location of the spring
retainer.
2. Press the safety clamp arm cover in until the safety clamp latches open.
3. Using E-ring pliers, insert the tips into the holes in the spring retainer.

case it is needed in the future.
5. Close the pump door to release the latched mechanism.
Spring Retainer Installation
The spring retainer is installed into the slide clamp slot at the factory to
maintain proper tension on the springs within the assembly. If the Insert Slide
Clamp option is not going to be used, the spring retainer should remain in the
assembly during pump use to maintain proper spring tension as well as to help
prevent the ingress of fluids into the mechanism. Instructions for installing the
spring retainer are provided below.
