PREPARATION & OPERATION
WARNING! Follow the instructions given in

pervisor for the safe operation of this machine.
Failure to do so can result in personal injury
and/or damage to the machine or property.
RECEIVING THE EQUIPMENT
Inspect equipment immediately and report any
damage or missing parts:
• Chassis – pump plate, squeegee and wheel
condition.
APPLICATIONS
Recommended surfaces:
• Vinyl and ceramic tile
• Sealed or finished concrete floors
• Wood, stone and terrazzo
TRANSPORT OF EQUIPMENT TO SITES
• Transport Position: The machine should be trans-
ported with the front swivel caster on the ground and
the chassis should be in the “up” or transport position.
Step on the foot pedal located on the right side of the
foot bar to place chassis in transport position.
• Do not drag squeegee across parking lots or thresh-
olds.
• Never lift tank by gripping the lid retainer ring.
OPERATION
1. Operating Position: Press down on the footbar
and lift on handle until chassis is locked down into the
operating position. Do not press the foot pedal located
on the right side of the foot bar.
2. Squeegee: Push the machine a few feet for-
ward until squeegee is laid out. A side to side motion
will help lay out squeegee for pick-up.
3. Solution Retrieval: A normal walking speed
assures nominal performance. The faster you go,
the better the machine works. If the pump stops
working, refer to TROUBLESHOOTING. When
foam escapes through breather hole in lid, the tank
is full and must be emptied. See CLEANING UP.
Note: If the floor is not being wiped dry, the squee-
gee may need adjustment. See TROUBLESHOOT-
ING.
4. Transport Upon Completion: Return the
chassis to the “transport” or “up” position. Any liq-
uid residue can be easily mopped up.
5. Clean Equipment:
a) Drain the tank - locate discharge valve at the front
of tank. Position for proper draining. Lift “T” handle
to regulate solution discharge. Tip machine forward
for complete drainage. Take care not to damage squee-
gee when draining.
DANGER! Solution will discharge in a large
steady stream with some pressure. Wear protec-
tive eye wear and avoid skin contact with all
chemicals used in this tank.
b) Rinse tank with warm water.
c) Remove return bellow from the top of the pump to
drain solution that is past the pump. Locate hose clamp
on top of pump and loosen, then slide tube off.
d) Tilt machine back to expose undercarriage for
cleaning. To tilt - rest unit on its’ foot bar and handle.
e) Rinse wheels, chassis and squeegee.
f) Drain pump by gently pressing on the inlet flapper
valve located in the center of the pump plate.
g) Flushing Pump: Hold a hose next to the inlet flap-
per valve while simultaneously activating the pump by
turning a drive wheel. Be sure to drain excess solution
from pump.
h) Reinstall return tube and tighten hose clamp.
6. Storage: It is very important to drain all liquid
from the unit if it is to be stored or transported in freez-
ing conditions.

MAINTENANCE
TROUBLESHOOTING
Problem: NOT LEAVING FLOOR DRY
Solution: • Remove debris collected between
the floor and squeegee. Wipe
squeegee of any debris.
• Adjust squeegee up or down to
obtain optimum performance. See
SQUEEGEE ADJUSTMENT.
• Check for nicks and/or tears in the
squeegee. Replace if necessary.
Problem: NOT PICKING UP LIQUID
Solution: • Try to reprime pump by crushing
the return bellow (item 28 in parts
list) with your hand and pushing the
machine forward quickly.
• Check inlet and outer flapper
valves for debris. Remove the
return tube bellow to check outer
flapper. If no debris is found, the
pump is worn or has not been
cleaned properly. See PUMP
SERVICE.
Problem: LEAKS.
Solution: See REPAIRING LEAKS section.

SQUEEGEE ADJUSTMENT
• Adjusting Squeegee - The three bolts which at-
tach the squeegee will also adjust the squeegee height.
Turn the bolts clockwise to raise the squeegee or
counter-clockwise to lower the squeegee. A 1/2 turn
should be enough. Be sure jam nuts are snug. Check
performance and adjust accordingly. See FIGURE 1.
PUMP SERVICE
• Cleaning Pump - Remove pump. Wash in warm
water. Make sure all debris is cleared from inner
and outer flapper valves. Check for worn parts and
replace if necessary.
• Adjusting Pump Plate - Loosen the four nuts
holding pump and adjust so black plate is 1/8” from
the floor. See FIGURE 2. Check for wear on foot
pedal.
• Rebuilding Pump - Remove pump. Replace in-
let, outlet and then diaphragm components of the
pump. Only tighten screws until tan hinge gasket
starts to squeeze out. Check pump for suction be-
fore reinstalling.
REPAIRING LEAKS
Isolate leak.
• Fitting Leak - Remove fitting, clean and smooth
the surface and/or gasket. Apply silicon and re-install.
• Body Leak - Contact Pacific.
