THIS SYMBOL POINTS OUT IMPORTANT SAFETY
INSTRUCTIONS WHICH IF NOT FOLLOWED,
COULD ENDANGER THE PERSONAL SAFETY
AND/OR PROPERTY OF YOURSELF AND
OTHERS. READ AND FOLLOW ALL INSTRUC-
TIONS.
- DISCONNECT BATTERY FROM CIRCUIT BEFORE
MAKING CHECK.
- To perform a continuity check of the switch, use a
continuity light or meter. Remove starter wire from starter
terminal of switch. With one of the continuity unit's
probes inserted in the brake start mechanism's terminal
red wire connector and the other lead to the starter
terminal (on switch), press the switch button; the light
or meter should indicate continuity. If not, replace switch.
If continuity exists without pressing switch button,
replace switch.

screw to make threads in the bracket, install the switch to
the brake bracket in the proper position and secure the
switch to the bracket with the machine screws.
- Be careful, over-tightening of the screws could break
the switch.
