Potentiometer Adjustment - Nilfisk-Advance BA 600S Service Manual

POTENTIOMETER ADJUSTMENT

1. Position the machine on a level ground.
2. Turn the ignition key (10) to "0" position.
3. Disconnect the battery connector (40).
4. Unscrew the screws (A) and remove the paddle (C) cover (B).
5. Disconnect one of the two microswitch (H) terminals.
6. Connect a 20 K Ohm tester to the potentiometer (G) connectors (D) and (E) and check the following values under
the following conditions:
– with the paddle (C) deactivated: from 2.40 to 2.60 K Ohm;
– with the paddle (C) set to forward: from 4.80 to 5.00 K Ohm;
– with the paddle (C) set to reverse: from 0.00 to 0.25 K Ohm.
CAUTION!
Do not invert the cables to the potentiometer (G) connectors (D), (E), (F).
7. To obtain the above conditions, loosen the nut (K) and turn the potentiometer (G) as necessary. Tighten the nut.
If the specified values can not be obtained by rotating the potentiometer (G), it is also possible to adjust the cam (J)
position after loosening the screws (I); in that case it will be necessary to adjust the machine forward microswitch
(H) (see the procedure on the following page).
8. Carry out steps 3 to 5 in the reverse order.
CAUTION!
Reconnect the microswitch (H) disconnected cable to the correct terminal (microswitch terminals "C"
