erly grounded fluid hose and pump.

System Accessories

Fig. 2 is only a guide for selecting and installing
system components and accessories. Contact your

Air and Fluid Hoses
Be sure all air hoses (H) and fluid hoses (N and P) are
properly sized and pressure-rated for your system.
Use only electrically conductive hoses. Fluid hoses

must have spring guards on both ends. Use a whip
hose (P) and a swivel (R) between the main fluid hose
(N) and the gun (S) to allow freer gun movement.
