Tech Guide to the WDP A4
Welcome, to the technical guide for the WDP A4, brought to you by Rikter7 Paintball. This step-by-step, photo intensive guide was designed to familiarize yourself with the technical workings of your marker and assist you with marker functionality. This guide was designed to assist you in maintaining your marker and all numbers, or steps are supported with direct quotes or information from the WDP issued manual. However the steps, methods or pointers seen in many of the photos may not follow step-by-step that of the manual but all were performed on a functional A4 and proved to be successful upon completion.
The walkthrough will be broken into three comment sections per technical routine:
1.) In RED
will be what the manual says on the routine.
2.) In BLUE will be how it was
performed in the photo.
3.) In ORANGE will be any additional
pointers or suggestions to make it easy on you.

DISCLAIMER
While this guide was created to assist you it does require a steady hand, common sense and the reading level equivalency of a 6th grader. Some of the technical procedures require the specified tools and failure to follow the steps provided by the manual in dealing with these routines may cause damage to your marker or perhaps personal injury. I am in no way responsible for your illiteracy, incompetence or stupidity in using this guide.
