3. Turn the potentiometer shaft using a slotted
screwdriver so that the resistance between the
upper terminals
1
and 2 is minimum between
1
ohm and
1
5 ohm. Leave the terminals (6 pieces)
of the potentiometer disconnected.

4. Remove the hexagon socket head bolts (4 pieces),
take out the potentiometer and fully tighten the
bolt for fixing the lever. Then install the
potentiometer and make sure that the resistance
between the upper terminals
1
and 2 is
1
5 ohm or
less.
2.2 Soldering
1
. After finishing the potentiometer adjustment,
remove the hexagon socket head bolts (4 pieces)
and take out the potentiometer. Then solder the
wiring to the terminals (6 pieces).
2. To insulate the terminals (6 pieces) from one
another, coat the terminal section with epoxy
adhesive (equivalent to 3M DP-420).
