NOTE:
Do not spray the linear actuator with the pressure
washer.
It will be necessary to
lubricate the three grease points
shown in Figure 5-3 every 40 hours or after every power
washing.
NOTE:
It will be necessary to remove the actuator
cover to access the center grease zerk.
BAC-VAC™ Hopper Switch Adjustment
Occasionally it may be necessary to adjust the sensor
switches on the hopper door. These switches, when adjusted
properly, make sure that the hopper door is closing and seal-
ing properly.
1.
Ensure that the BAC-VAC™ is fully mounted and that
the hopper wire harness and the mower frame harness
are connected.
2.
With the hopper door closed and the ignition switch in
the “ON” position, press the control switch on the
mower so that the door opens.
Allow the door to open fully. If the actuator makes a
ratcheting sound before the door stops moving, then the
angled sensor switch needs to be adjusted so that more
of the plunger is exposed out of the switch’s control
body. The plunger depth is adjusted by loosening the two
screws, repositioning the switch body, and then
tightening the screws. Figure 5-4
Repeat the test and adjustment until the door stops its
opening motion before the actuator ratchets.
3.
With the door open, press the switch on the mower so
that the door closes.
The sensor switch should have a .5 second delay. Allow
the door to close. The door should close and compress
the door/shell joint and the actuator should ratchet and
after approximately .5 seconds the ratcheting should
stop.
If the actuator does not ratchet then the horizontal
sensor switch needs to be adjusted so that less of the
plunger is exposed out of the switch’s control body.
If the actuator does not stop ratcheting then the
horizontal sensor switch needs to be adjusted so that
more of the plunger is exposed out of the switch’s
control body.
4.
After the switches are correctly set, open the door and
adjust the two turnbuckles by tightening them by two
complete revolutions. Tighten the jam nuts on the
turnbuckles. Figure 5-5
