BACKHOE LOCKS
The backhoe locks are used to secure the backhoe unit in a travel posi-
tion. These locks must be used when traveling with the machine or
using the front end loader. To use the backhoe lock:
1. When the machine is in operation and the backhoe is being oper-
ated the boom lock for the backhoe should be disengaged.
2. To use the backhoe boom lock, locate the switch positioned on the
left instrument bezel as viewed from the operator’s position when
operating the backhoe.
3. Fold the arm, boom and bucket up completely.
4. Once the arm, boom and bucket are folded up completely, press the
boom lock switch (1) and engage the boom locking device (2).
5. Once the locking device (2) is set, center the backhoe unit to align
the lock pin holes in the backhoe mounting boss.
6. Remove the centering pin (3) from it’s holding location and insert it
in locking holes in the backhoe mounting boss.
7. Be sure the pin (3) drops down completely and is flush with the top
of the backhoe boss. Keep in mind once the lock pin (3) is installed
the backhoe assembly will not swing
8. Once the pin (3) is in place, lock the backhoe wobble stick control-
lers (4) using the locking lever (5).
9. Move the wobble sticks (4) to be sure the are locked
10. If you will be traveling or using the front end loader for a long
period of time you may want to lock the outriggers in place to avoid
possible hydraulic drift.
11. To lock the outriggers, retract both outriggers completely. The lock-
ing lever (5) must be unlocked to raise the outriggers.
12. Install the locking safety cables (6) on both outriggers and be sure
to re-lock the wobble stick lock (5).
Remark
The lock pin and the safety cables must remain with the
machine. If they are lost or damaged, they must be replaced.
