CLEANING
• Cleaning of the hydraulic system when changing oil is nor-
mally not necessary. If the system becomes contaminated
due to unusual circumstances (defect, etc.), then it must
be thoroughly cleaned before recommissioning. Housings
and pipelines must be flushed. If necessary, the pipelines
and hydraulic units must be disassembled.
SERVICE
• Maintenance and repairs should be undertaken only by
skilled personnel who are familiar and trained with the
equipment. PRO-DIG
service capable of carrying out the work of repair and
overhaul if required.
• Only spare parts specified in the PRO-DIG
catalogues should be used. The serial number stamped on
the unit type plate is relevant to the configuration of the
unit. Therefore, the serial number should be quoted when
ordering spare parts.
OIL SELECTION AND VISCOSITY RECOM-
MENDATIONS
Suitable hydraulic oils are:
• Mineral oil HLP to DIN 51524
• Biodegradeable fluids upon request
• Other pressure fluids upon request
Your Pro-dig Planetary Auger Drive receives its hydraulic oil flow and pressure from the parent machine through the auxiliary
hydraulic circuit via two quick release couplers near the end of the truck boom or excavator arm.
CAUTION: Alert yourself to the weight of the Auger Drive. Do NOT exceed the recommended lift capacity of the parent machine.
Refer to you machines owners manual.

SET-UP INSTRUCTIONS
PRO-DIG
recommends only using hydraulic oils which are
®
confirmed by the producer as suitable for use in high pres-
sure hydraulic installations. For the correct choice of suitable
hydraulic oils, it is necessary to know the working temperature
in the hydraulic circuit. The hydraulic oil chosen must allow
the working viscosity to be within the optimum viscosity range
(as shown below).
Attention: Due to pressure and speed influences, the tem-
perature of the leakage fluid is always higher than the circuit
temperature. The temperature must not exceed 90°'b0C in any
part of the system. Under special circumstances, if the stated
conditions cannot be observed then please consult Linde.
Recommended viscosity range for optimum performance:
15 cSt to 30 cSt
• Maximum allowable working viscosity range:
10 cSt to 80 cSt
• Viscosity limitations: 6 cSt minimum viscosity
1000 cSt maximum viscosity (Intermittent for
cold starts)
• Oil temperature limitations: (-20)°'b0C to 90°'b0C
