IMPORTANT: The door lock should be checked daily to ensure proper operation. Also check that all safety
and instruction stickers are on the machine. Any missing or illegible safety and/or instruction stickers should
be replaced immediately.
Beginning of the Day
1. Inspect the water inlet valve hose connections on the back of the
machine and at the faucets for leaks.
2. Inspect the steam hose connections for leaks (where applicable).
3. Verify that the insulation is intact on all external wires and that
all connections are secure. If bare wire is evident, call a service
technician.
4. Check the door interlock before starting operation:
a. Attempt to start the machine with the door open. The
machine should not start with the door open.
To reduce the risk of electrical shock, serious injury
or death, disconnect the electrical power to the
washer-extractor before examining the wiring.

1. Check the washer-extractor for leaks:
a. Start an unloaded cycle to fill the washer-extractor.
b. Verify that the door and door gasket do not leak.

NOTE: Disconnect power to the machine at its source before performing the monthly maintenance
procedures.
1. Each month or after every 200 hours of operation, lubricate the
bearings. Locate the bearing lubrication decal on the rear, right
of the washer-extractor.
a. The lubricant must have the following characteristics:
- NLGI Grade 2 - Water-insoluble - Anti-oxidizing
- Lithium-based - Anti-rusting - Mechanically stable
The lubricant must have adequate base oil viscosity with one
of the following ratings:
- ISO VG150 (135-165 CST at 40°C or 709-871 SUS at
100°F
- ISO VG 220 (198-242 CST at 40°C or 1047-1283 SUS at
100°F
- An SAE 40 rating is also acceptable as long as the CST or
SUS values are within the specified ranges
b. Pump the grease gun slowly, permitting only 2 strokes.
2. Use the following procedures to determine if the V-belt(s)
require replacement or adjustment. Call a qualified service
technician in either case.
a. Check the V-belt(s) for uneven wear and frayed edges.
b. After disconnecting power to the washer-extractor and
removing all panels necessary for access to the drive belt, use
one of the following methods to verify that the v-belts are
properly tensioned.
•Tension Gauge. Loosen the motor mounting bolts and slide
the motor along the motor plate to change the span length.
UWPV belt tension should be between 70 and 90 pounds
(± 5 pounds). Set the initial tension toward the high end of
this range.

•Deflection. Loosen the motor mounting bolts and slide the
motor along the motor plate to change the belt span length.
Belt tension measurements should be taken as close to the
center of the belt span as possible. For every inch of span
length, the belt should deflect 1/64 inch (0.40mm). For
example, a belt with a span length of 50 inches should deflect
50/64 inches (19.84mm). An initial (run-in) force of 5.25
pounds should be used to set the belt tension. An operating
(normal) force of 3.5 pounds should be used after the
washer-extractor has operated for a few hours.
c. Verify that the V-belts are properly aligned by checking the
pulley alignment. Place a straightedge across both pulley
faces. The straightedge should make contact with the pulleys
in four places.
3. Remove the back panel and check the overflow hose and drain
hose for leaks.
4. Unlock the hinged lid and check the supply dispenser hoses and
hose connections.

4. Check all painted surfaces for bare metal. (Matching paint is
available from the manufacturer.)
• If bare metal is showing, paint it with primer or with a
solvent-based paint.
• If rust appears, remove it with sandpaper or by chemical
means and then paint the affected area with primer or with a
solvent-based paint.
5. When applicable, clean the customer-supplied steam filter.
a. Turn off the steam supply and allow time for the valve to
cool.
b. Unscrew the cap.
c. Remove the element and clean it.

✓Remove dirt and grease with detergent and water.
Thoroughly rinse and dry after washing.
✓Avoid contact with dissimilar metals to prevent
galvanic corrosion when salty or acidic solutions are
present.
✓Do not allow salty or acidic solutions to evaporate
and dry on stainless steel. Wipe clean of any
residues.
✓Rub in the direction of the polish lines or “grain” of
the stainless steel to avoid scratch marks when using
abrasive cleaners. Use stainless steel wool or soft,
non-metal bristle brushes. Do not use ordinary steel
wool or steel brushes.
✓If the stainless steel appears to be rusting, the source
of the rust may be an iron or steel part not made of
stainless steel, such as a nail or screw. Tip: Paint all
carbon steel parts with a heavy protective coating.
Stainless steel fasteners should be used whenever
possible.
✓Remove discoloration or heat tint from overheating
by scouring with a powder or by employing special
chemical solutions.
✓Do not leave sterilizing solutions on stainless steel
equipment for prolonged periods of time.
✓When an external chemical supply is used, ensure
no siphoning of chemicals occurs when the washer-
extractor is not in use. Highly concentrated
chemicals can cause severe damage to stainless steel
and other components within the machine. Damage
of this kind is not covered by the manufacturer’s
warranty. Locate the pump and tubing below the
washer-extractor’s injection point to prevent
siphoning of chemicals into the machine.
