CAUTION!
ii
To reduce the chance of personal injury and/or property damage, the following
instructions must be careful observed:
Proper service and repair are important to the safety of the service technician
and the safe reliable operation of all cleaning equipment. If part replacement
is necessary, the part must be replaced with one of the same part number or
with an equivalent part. Do not use replacement parts of lesser quality
The service procedures recommended and described in this service manual
are effective methods of performing service and repair. Some of these
procedures require the use of tools specifically designed for the purpose.
Accordingly anyone who intends to use a replacement part, service procedure
or tool which is not recommended by the equipment manufacturer, must
determine that neither his safety nor the safe operation of the equipment will
be jeopardized by the replacement part, service procedure or tool selected.
It is important to note that this manual contains various cautions and notices
that must be carefully observed in order to reduce the risk of personal injury
during service or repair, or the possibility that improper service or repair may
damage the piece of equipment or render it unsafe. It is also important to
note that these ‘Cautions’ and ‘Notices’ are not exhaustive, because it is
impossible to warn of all the possible hazardous consequences that might
result from failure to follow these instructions.
