Grounding

The equipment must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static build
up.

Connect grounding wire to grounding screw (Z) on back
of XM sprayer or any earth ground.

Install Feed Pump

NOTE: President 10:1 feed pump kit 256433 is only

recommended for drum feed applications and highly
viscous materials. Do not install in hoppers as this will
result in pulsation at the gun. See page 11 for parts.

1. Refer to Setup instructions in the pump manual

before installing in drum or hopper (H).

2. If installing either the pump in a drum, install pump
in drum and use bung adapter (B) to secure.

3. If installing the T2 pump in a hopper: Install T2
pump in lower ledge of hopper (H), and secure with
