prevention.
Follow this procedure:
1. Pour half a gallon (2 liter) of mineral spirits into a bare
metal pail. Put suction
tube into pail.

with a metal part of gun firmly
touching
the metal
container,
squeeze trigger.
Now pull the switch
out
to ON position
and turn

Hold trigger
fully
open
until
clean solvent
comes
from
nozzle,
then release it. Keep gun aimed into pail until all fluid
flow
stops.
Engage
trigger
safety.
This
procedure
avoids splashing
and static sparking.
3. Check all paint line fittings
for leaks while system
is
pressurized.
If there are any leaks, relieve pressure
according
to Pressure Relief Procedure.
Then tighten
fittings,
start pump and recheck fittings
to be sure all
leaks have stopped.
