Section 5 Service Procedures
To reduce the risk of electrical shock, fire, explosion, serious injury or death:
• Disconnect electrical power to the washer-extractor before servicing it.
• Close the gas shut-off valve to the washer-extractor (when applicable) before servicing it.
• Never start the washer-extractor with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the washer-extractor is properly grounded.

NOTE: Do not attempt to measure motor current
with a clip-on Amp meter on UWPV machines.
Incorrect readings will result.
The Amp meter can be used to detect excessive
electrical current draw that causes overloads on
breakers and fuses. The Amp meter clamps
around the current-carrying wire. Refer to the
instructions furnished with the meter.
The volt/ohm meter will measure volts when set
on “volt.” It will measure ohms (resistance) when
set on “ohm.” This setting can also be used for
continuity testing.
As mentioned in safety warnings, the power to the
machine must be disconnected before servicing.
Wires should be disconnected from the
component or components being checked. Using
the ohm meter, test leads are placed in contact
with the terminals being checked.
For example:
To check any switch, set the ohm meter to the
“ohm” scale as outlined in the meter’s operating
instructions. Place one lead on each terminal.
Refer to Figure 3. Depress the switch button. If
the switch is making contact, the needle on the
meter will move towards the “0” end of the ohm
scale. This indicates continuity through the
switch. When the switch button is released, the
needle will move back to its original position.
Continuity through wires can be tested in the same
manner.
NOTE: Computer controlled machines must have a
proper ground to prevent computer malfunctions.

To reduce the risk of bodily injury and/or
property damage such as fire, electric
shock or equipment damage, washer-
extractors must be installed, adjusted and
serviced by qualified electrical maintenance
personnel familiar with the construction and
operation of the type of machinery. These
personnel must also be familiar with the
potential hazards involved. If this warning is
not observed, personal injury or equipment
damage (that may result in voiding the
warranty) can occur.
WARNING
To reduce the risk of electrical shock, be
sure that a ground wire from a proven earth
ground is connected to the chassis ground
lug in the electrical junction box on the
machine. Without proper grounding,
personal injury from electrical shock may
occur and machine malfunctions may be
evident.
WARNING
To reduce the risk of injury, replace all
panels that have been removed to perform
service and maintenance procedures, do
not operate the machine with guards
removed or with parts missing or broken
and do not bypass any safety devices.
