Section 4

Service

Caution

The procedures outlined in this section shall be performed by

persons experienced in servicing and maintaining laboratory equipment.
Lockout and tagout electrical power connections whenever removing
cabinet panels or working on electrical or motor control components.

s

With the exception of replacing the drive v-belt and the six electrical fuses,
the SHKE420HP Orbital Shaker contains no user-serviceable components.
The following lists display messages which may help diagnose abnormal
conditions.

If the microprocessor control system senses a fault, malfunction or
abnormal operating condition, alarm messages appears on the liquid crystal
display. These messages will be helpful should service or repair assistance be
necessary.
