Before Using the Digger
IMPORTANT
The digger was shipped without oil in the gearboxes. Oil must be added to the gearbox before
operating.
Note: Fill the gearbox using gear oil (type 80W-90 lubricant) and fill to the oil level plug. Check the
gear box every fifty hours of use to assure adequate lubrication.
Note: Check all nuts and bolts for tightness. Stabilizers should be kept tight to avoid the side sway of
the digger.
Adding and Changing Gearbox Oil
1. Using a 7/8” wrench, remove the 1/2” vented pipe plug located on front of the gearbox above the
PTO shaft.
2. Remove the check plug located at back of the gearbox.
3. Fill the front of the gearbox with gear oil until it begins to overflow from the check plug hole in
the rear.
