8 Start/stop switch
8.1 Disassembly
1. Remove the stop switch with a screwdriver and
detach the leads. See fig. 1.
8.2 Cleaning and inspection
Carefully clean and check all components. Parts must
be replaced if cracked or if they show signs of other
defects. Always use original spare parts.
Measure the resistance by connecting an ohmmeter to
the stop switch. See fig. 2. The resistance should be as
follows:
”0” pressed in - less than 0.1 ohm.
”1” pressed in - more than 1000 ohm.
8.3 Assembly
The symbol/stop marking should be mounted to the
rear hand grip during assembly. The earth lead is fitted
in the upper or lower connection. See fig. 2.
8.4 Function check
Clean the mating surfaces and do a check of the resis-
tance as follows:
Measure the resistance by connecting a multimeter to
the blue cable and the cylinder (earth).
NOTE! The switch must be in the “on” position to give
the correct reading.
The resistance must not be higher than 0.5
Ω
when the
switch is in the on position.
The stop switch is in the ON-position when the button is
held down and in the OFF-position the button is neutral.
