Graco Gusmer Reactor H-25 Operation page 21

12. Ground system
a.
Reactor: is grounded through power
cord. See page 17.
b.
Spray gun: connect whip hose ground
wire to FTS, page 19. Do not disconnect
wire or spray without whip hose.
c.
Fluid supply containers: follow your local
code.
d.
Object being sprayed: follow your local
code.
e.
Solvent pails used when flushing: follow
your local code. Use only metal pails,
which are conductive, placed on a
grounded surface. Do not place pail on
a nonconductive surface, such as paper
or cardboard, which interrupts ground-
ing continuity.
f.
To maintain grounding continuity when
flushing or relieving pressure, hold a
metal part of spray gun firmly to the side
of a grounded metal pail, then trigger
gun.
13. Check hydraulic fluid level
Hydraulic reservoir is filled at the factory. Check
fluid level before operating the first time, and
weekly thereafter. See Maintenance, page 33.

LR
b.
Fill with fresh lubricant. Thread the res-
ervoir onto the cap assembly and place
it in the bracket (RB).
c.
Push the larger diameter supply tube
(ST) approximately 1/3 of the way into
the reservoir.
d.
Push the smaller diameter return tube
(RT) into the reservoir until it reaches
the bottom.
Important: The return tube (RT) must reach the
bottom of the reservoir, to ensure that isocyanate
crystals will settle to the bottom and not be
siphoned into the supply tube (ST) and returned to
the pump.
e.
The lubrication system is ready for oper-
ation. No priming is required.
