SECTION 1. TROUBLESHOOTING
1-1. INTRODUCTION This section provides troubleshooting information in the
form of an easy to read table.
If a problem occurs during the first operation of a new
rotisserie, recheck the installation per the Installation
Section of the Operator’s Manual.
Before troubleshooting, always recheck the Operation
Procedures Section of the Operator’s Manual.
1-2. SAFETY Where information is of particular importance or is safety related,
the words NOTICE, CAUTION, or WARNING are used. Their
usage is described below .
SAFETY ALER T SYMBOL is used with DANGER,
W ARNING, or CAUTION which indicates a personal injury
type hazard.
NOTICE is used to highlight especially important information.
CAUTION used without the safety alert symbol indicates
a potentially hazardous situation which, if not avoided, may
result in pr operty damage.
CAUTION used with the safety alert symbol indicates a
potentially hazardous situation which, if not avoided,
may result in minor or moderate injury.
W ARNING indicates a potentially hazardous situation
which, if not avoided, could result in death or serious
injury.
1-3. TROUBLESHOOTING T o isolate a malfunction proceed as follows:
1. Clearly define the problem or symptom and when it occurs.
2. Locate the problem in the troubleshooting table.
3. Review all possible causes, then one at a time work
through the list of corrections until the problem is solved.
If maintenance procedures are not followed corr ectly,
injuries and/or property damage could result.
