SAFETY INTERLOCK SYSTEM
Your machine is equipped with a safety interlock system which prevents the engine from starting
unless a vacuuming attachment and the fan cover are installed.
The system also stops the engine if the operator attempts to remove an attachment or the fan cover
while the engine is running.
If the safety interlock system fails, shut off the engine and do not operate the machine until the system
has been repaired. Contact your local servicing dealer or the factory for assistance.
Testing the Safety Interlock System
The following test should be performed prior to each day’s use of your machine.
1. Start the engine.
2. Disconnect the three-pronged connector (on end of cord extending from attachment) - See fig. 1.
•
If the engine begins to stall, the system is working properly. Reconnect the three-pronged connec-
tor by gently but firmly pushing the connector onto the switch. The two longer prongs fit on either
side of the switch button housing; the shorter prong depresses the switch button.
•
If the engine does not begin to stall, it means that the system is not functioning properly (Briggs &
Stratton.) Stop the engine by moving the Engine Throttle Control (on right side handlebar) to the
STOP position. (Honda) Turn switch on side of engine to off position. Refer to Figure 1, Page 19.
Disconnect the spark plug wire from the spark plug. Do not operate the machine until the safety
interlock system has been inspected and repaired.
WARNING
To avoid personal injury or property damage, do not operate machine unless
safety interlock system is functioning properly.
