Top Limit reed switch adjustment
• The power swivel needs to get a signal
from the reed switch inside the rail to work.
Therefore the reed switch may need moving
upward to the magnet housed inside the
hollow rolled section (captive by M6 hex
head screw facing downward on the fix foot).
• The centre of the reed switch should be
approximately 20mm away from the centre
of the magnet.
Figure 65
20mm
• There is a dogging hole that the reed switch
locates in for a reference. This can be
overridden by depressing the inside of this
hole to depress the catch, and then slide the
reed switch up the channel to get a signal.
