Adjusting Bucket Limit Switch - Labrie TOP SELECT Maintenance Manual

50 Loading Container Maintenance
• If the unloading angle is smaller than 45° when the bucket reaches the stoppers, you will need to
shorten the length of the rods to meet the angle requirement (angle must be set between 45°
and 50°).
• If the bucket slams on the sliding shoe on its way up, you will need to lengthen the rods to
correct this.
Once you reach a good compromise between those two references (that is the unloading angle and
the free course of the bucket), the adjustment process is completed.
N : Make sure to tack weld the locknuts once you are finished with the adjustment.

DANGER!
Always apply the Lockout/Tagout procedure before doing any adjustment or repair (see
Lockout/Tagout Procedure on page 22).

Adjusting Bucket Limit Switch

The backup alarm should sound as soon as the bucket starts moving. If this is not the case, you must
adjust the bucket limit switch using the following procedure.
To adjust the bucket limit switch:
1.
Raise the loading bucket and locate the corresponding limit switch.
2.
Use an Allen key to adjust the length and angle of the limit switch arm.
The limit switch must be adjusted in such a way that the backup alarm starts sounding as soon as
the loading bucket starts rising.
This safety feature is provided to warn people around to stay away from the vehicle to avoid
possible injury and to remind the operator that the loading bucket is still raised.
3.
Move the bucket up and down a few times to test the adjustment.
4.
Readjust if necessary.
