• Good maintenance is your responsibility. Poor maintenance is an invitation to trouble.
• Always use proper tools or equipment for the job at hand.
• Use extreme caution when making adjustments.
• Never use your hands to locate a hydraulic leak on attachments. Use a small piece of cardboard or wood. Hydraulic fluid
escaping under pressure can penetrate the skin.
• Hydraulic fluid escaping under pressure can penetrate skin and cause injury.
• Fluid accidentally injected into the skin must be surgically removed within a few hours by a doctor familiar with this form
of injury or gangrene may result.
• When disconnecting hydraulic lines, shut off hydraulic supply and relieve all hydraulic pressure.
• Clean hydraulic oil daily for contamination. If contamination is present, determine the source and correct the problem.
• When replacing bolts refer to this manual.
• Clean the exterior of the unit with a mild detergent and water to remove any debris and grime.
• Paint all scratched or bare metal surfaces.
• Check and tighten all bolts, nuts, and screws.
• Repair or replace any cutting head components that are damaged or worn.
• Check the gearbox for sufficient amount of oil.
• Check the PRO-DIG
™
Auger Drive output shaft for bends, cracks, breaks, or wear. Replace if any of these conditions appear.
• Where replacement parts are necessary for periodic maintenance and servicing, genuine factory replacement parts must
be used to restore you unit to original specifications. PRO-DIG

CHECKING AND CHANGING THE GEAR OIL
The Planetary gearbox used on your PRO-DIG
To check and or replace the oil, follow these simple steps.
CHECKING THE GEAR OIL:
1. Make sure the PRO-DIG
™
Auger Drive unit is in an upright
position when checking the oil.
2. Slowly loosen the oil fill-drain plug located on the under
side of the gearbox. As you reach the end of the threads on
the plug, oil should start to come out.
3. If you see oil starting to pour out of the port, quickly retighten
the plug. This is an indication that the oil level is adequate, but
in order to correctly measure the amount of oil, the gearbox
should be drained and the correct amount of oil replenished.
See "Changing Gear Oil" section for oil capacity.
CHANGING THE GEAR OIL:
1. Position the PRO-DIG
™
Auger Drive unit in a position in
which the oil can flow freely from the gearbox once the
plug is removed.
2. Place a drain pan under the drain port that will hold at
least one gallon of oil.

3. Remove the drain plug and allow the oil to completely drain out.
4. Position the gearbox for filling by orientating the unit so that
the same port used for draining can now be used to fill.
5. Fill the gearbox with 0.75 Gallons/2.84 Liters of gear oil.

LUBRICATION AND MAINTENANCE
The oil should be changed after the first 50 hrs. of use and at
500 hr. intervals thereafter. Geardrives in auger drives require
GL-5 grade EP 80/90 gear oil for lubrication. PRO-DIG
mends that the unit be partially disassembled to inspect gears
and bearings at 1000 hr. intervals.
