This Driver is not intended to be submerged in water or mud. Such action would result in the piston or similar
parts becoming permanently damaged by corrosion.
4.9. Do not vertically fall the Breaker to crush rocks.
If the Breaker directly falls onto the rocks to be crushed, the Breaker or the excavator would bear excessive
forces, which would easily damage the excavator parts.
4.10. Do not make the striking operation when the oil cylinder on the excavator boom reaches its greatest travel
distance.
When the oil cylinder rod of the excavator reaches its greatest travel distance (the oil cylinder rod is fully
extended or withdrawn), the breaking operation could cause damage to the oil cylinder and different parts of the
excavator.
4.11. Do not use ropes, chains, etc. to suspend objects under the Breaker.
In addition to being quite dangerous, suspending objects under the attachment could easily damage the Breaker.
4.12. In cold weather, the engine should be preheated before operation according to the operation and maintenance
instructions of the excavator (~5-20 minutes).
Low temperature breaking operation without preheating the engine could easily damage the parts of the Breaker
such as the piston and seal.
AUGER DRIVE UNIT
1. After all installation instructions have been completed, all safety information has been read and understood, and the
rest of this operator’s manual has been reviewed, your Hydraulic Earth Auger will be ready to use.
2. Check that the auger teeth and points are in good condition. This should be maintained frequently. Always keep spare
parts on hand so that they can be replaced as wear is detected, which should help to avoid causing unnecessary
damage to the tooth holders and auger flighting.
3. Remove the hairpin cotter pin from the auger system’s locking pin. Carefully lower the auger and then secure the locking
pin back in place.
4. Put the diverter valve lever fully in the “up” position to enable the auger system hydraulics.
5. With the auger raised off the ground and the vehicle engine set at low RPM, activate the earth auger control valve. The
control valve lever must be in to turn the auger in a forward (clockwise) rotation. This is the “digging” position.
6. Before beginning to dig, experiment with auger speed to determine a suitable RPM. Generally, in light and sandy soil,
a high RPM is desirable; whereas, in hard, rocky, or frozen soils, a slower RPM is preferable. To increase or decrease
the auger RPM, increase or decrease the engine RPM.
7. Return the earth auger control valve to the neutral position to stop the auger. Lower the auger to the ground so that only
the auger’s pilot point penetrates the ground by about 2 inches.
Avoid excessive side loading to the earth auger, which can cause drive unit or auger damage.
8. Activate the earth auger control valve so that the auger is turning in a forward (clockwise) rotation. Use only enough
down pressure to assure positive penetration of the auger into the ground.
