3
Place the end of the fill
hose over the fill fitting
on the gun.
4
Pump mud from
the bucket into the
ENFORCER™. The
number of pumps
required to fill the tank
will vary depending on
the material viscos-
ity and pump stroke,
but 20-25 pumps is typical. When the
ENFORCER™ is full it will become signifi-
cantly harder to pump. Stop pumping at this
point. DO NOT OVER-PUMP. DOING SO
COULD RESULT IN COMPONENT FAILURE
AND SERIOUS INJURY.
5
Once the system is full,
remove the hose from
the fill fitting on the gun.
Replace the cap on
the top port plug in the
gun ensuring a secure
fit. Place the end of the
mud fill hose back into
the bucket to avoid overflow of material.
6
Now flip the toggle
switch back to spray
and you're ready to go.
Cleaning
The frequency of required cleaning will vary
by material, frequency of use, and environ-
ment. ALL MATERIALS OTHER THAN
DRYWALL COMPOUND SHOULD BE
CLEANED AFTER USE. As a general rule
of thumb, if drywall compound will be, or
has been, in the tank for more than 2 weeks
without use the unit should be cleaned out.

Performing regular maintenance and cleaning
will extend the life of your ENFORCER™ and
its components.
DO NOT HOOK THE ENFORCER™ UP TO
ANY WATER LINE. DOING SO COULD
RESULT IN COMPONENT FAILURE AND
SERIOUS INJURY.
1
After every use the ori-
fice of the gun should
be cleaned. For best
results, separate the
gun and orifice plate
and flush each with
clean water.
2
For a more thorough
cleaning, empty all left
over mud by opening
the mud flow control to
the highest setting and
spraying the material
into a bucket.
3
Next, open the tank by
removing the top cap
assembly and piston
and fill with clean water
while washing of the
bottom of the tank.
4
Replace the piston and
lid and spray the clean
water through.
Repeat steps 3 and 4
until the sprayed water
is clear.
Remove the gun and scrub as necessary.
Leave the lid and gun off the wet unit to
reduce mold build-up.
Re-lubricate the piston seals and cap o-rings
after cleaning. Now the ENFORCER™ is
ready for the next job
