HOPPER ROTATION ACTUATOR CHECK AND ADJUSTMENT
Check
Remove the main broom (see the procedure in the relevant paragraph). 1.
Slightly lift the hopper (31) (see the procedure in the User Manual); then lower the hopper (31) again but stop it when the upper 2.
rear side (A) is at 0.8 in (2 cm) (B) from the machine frame.
Turn the ignition switch (17) to “0”. 3.
WARNING!
The hopper (31) can close accidentally.
When the distance (B) is reached, check that the front distance (E) of the hopper from the machine frame is 0.4-0.8 in (1-2 cm) 4.
bigger than the distance (B). If the measures are not as shown in step 4, adjust the hopper rotation actuator (F), according to
the following procedure.
Adjustment
Lift the hopper (31) in order that the hopper rotation actuator (A) is high enough to allow adjustment (for hopper handling, see 5.
the procedure in the User Manual).
Do not dump the hopper, keep it horizontal.
Apply a proper safety stand under the lifted hopper to prevent it from lowering incidentally. 6.
WARNING!
Apply a proper safety stand under the lifted hopper even if the hopper lifting hydraulic cylinder is equipped with
a parachute valve which prevents the hopper from lowering suddenly in case a hose breaks or leaks.
Remove the nuts (H) and insert the threaded pins (I) of the limit switch for approximately 0.2 in (5 mm). 7.
Remove the microswitch protection covers (L) by releasing the relevant inner fasteners. 8.
NOTE
To adjust the hopper rotation actuator, take into consideration that:
The microswitch (M) indicates that the hopper is horizontal. –
The microswitch (N) indicates the hopper maximum vertical position.
–
When the hopper is in the horizontal position, the tilted head of the stem (P) is in the position (O) as to the –
microswitch (M).
When the hopper is in the maximum vertical position, the tilted head of the stem (P) is in the position (Q) as to the –
microswitch (N).
Check the mounting screws (S) and (T) of the microswitch collars (N) and stem collars (P) for proper tightening, otherwise 9.
tighten them.
Loosen the screw (R) and adjust the position of the collar/microswitch assembly (M), as shown below: 10.
If the distance (E) should be increased, move slightly the collar/microswitch assembly (M) in the direction of the arrow (U), •
then tighten the screw (R)
If the distance (E) should be decreased, move slightly the collar/microswitch assembly (M) in the direction of the arrow (V), •
then tighten the screw (R).
Perform again the above check (see steps 1 through 4). 11.
Remove the threaded pins (I) until they reach the lever (W); then tighten the nuts (H). 12.
Fully retract the hopper (31). 13.
Install the main broom (see the procedure in the relevant paragraph). 14.
