463280 - 9/14 Terex South Dakota, Inc. Digger Derrick
OPERATION GUIDELINES
DIGGING OPERATIONS
1. Before lowering or storing auger, make certain that all ground personnel are clear and the boom is
raised high enough (approximately 45 to 50 degrees) and so the auger clears the vehicle body.
2. Maintain proper clearance from all power lines.
3. Do not stand in auger path.
4. Use low speed only to store and un-store digger. Do not shift speeds with digger in stored position; this
will allow auger to free spin. Shift to high speed only when digger is un-stored.
5. A free-swinging auger can cause serious injury or death.
LOWERING THE DIGGER/AUGER
To properly lower the digger, the following steps should be taken to ensure a safe operation:
1. “BEWARE” of overhead lines. Inform your surrounding ground personnel that you are about to un-store
the auger.
Raise the boom to approximately 45 to 50 degrees.
Remember, if the digger is a two-speed digger, you must un-store it in “LOW GEAR”. You must also store it
in “LOW GEAR”. Do not shift when digger is storing or moving.
AUGER STORAGE LATCH OPERATION
2. Fully retract the second section, raise digger/auger by moving lever in the “DIG” direction to allow latch
to release.
3. Push and hold the auger release valve to open the latch. Release the auger release valve after the
auger clears the storage bracket.
4. Continue to lower the digger/auger slowly to vertical position and unsnap cable.
5. When the auger is un-stored, inspect the auger roll-up cable for damage. If any damage is found,
replace it.
6. To align the auger roll-up cable the second section may have to be extended.
Observe the following five rules to unstow or stow the digger/auger.
Intermediate boom section must be fully retracted prior to un-storing digger/auger.
