• 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.

CHECKING AND CHANGING THE GEAR OIL
The Planetary gearbox used on your PRO-DIG
lubricated. To check and or replace the oil, follow these simple steps.
CHECKING THE GEAR OIL:
1. Make sure the PRO-DIG
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
®
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 4.2 Gallons/15.8987 Liters of gear
oil. See oil specifications below.
LUBRICATION RECOMMENDATIONS:
Mobil Delvac Synthetic Gear Oil 75W-90
Density @15°C
Viscosity @40°C 138
Viscosity @100°C 15.9
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.
