shear bolt and replace the shear bolts. Tighten lock washers and hex nuts. (CAUTION: USE OF
SHEAR BOLT HARDER THAN GRADE TWO 2 FOR ETA COMPACT AND ETA 6900 OR
GRADE 3 FOR ETA 6900 HD COULD CAUSE DAMAGE TO YOUR GEARBOX). NOTE: A
longer or protruding shear bolt is more likely to grab loose clothing or gloves, which can result in
serious injury or death. Replace two halves of auger safety shield and secure with wing nuts.
Depress the locking spring on the (PTO) shaft (#11) and slide coupler onto tractor output shaft
until the PTO locking pin clicks in place. Make sure set screw (#10) is tight on PTO shaft at
gearbox. The setscrew holds the PTO shaft on the gearbox shaft if the PTO shear pin breaks. Fill
gearbox with 90W-gear oil. Unscrew ½” fill plug on top of gearbox and 1/4'' overflow plug on
side. Fill until oil runs out of side plug (about 1 Qt.). Install both plugs. Grease the PTO universal
joints, the metal PTO shaft and spray lube the plastic cover tube so that both will slide in and out
freely. Fasten chain on plastic PTO cover at gearbox to the hole in side of PTO shield. Fasten
PTO chain at the tractor end of the cover to the lift arms of the actor. This allows the shaft to turn
but the outside plastic shield remains stationary to protect the operator from becoming entangled
in the PTO shaft and thus causing personal injury.
3. PRE-USE CHECK LIST
Inspect the digger thoroughly after assembly to be certain it is set up properly before operation
and use the following checklist as a reminder of points to inspect. Check off each item as it is
found satisfactory or after proper adjustment is made.
- Check that all safety shielding is in place.
- Check all bolts to be sure they are tight.
- Check gearbox oil level. It is full when oil runs out of the overflow hole on side of gear
box (1/4 inch pipe plug). Use 90 weight gear oil.
- Check that all lubrication points and that all grease fittings have been lubricated
(2 fittings).
- Check that cutting edges have been properly installed on auger.
4. PREPARATION
- Always wear relatively tight and belted clothing to avoid entanglement in moving
parts. Wear sturdy, rough-soled work shoes. Never operate tractor or implements in bare
feet sandals, or sneakers.
- Clear area of branches or other debris that might be thrown by the auger, causing
personal injury or damage to the machine.
-
NEVER ALLOW ANYONE AT REAR OF TRACTOR OR NEAR AUGER
WHILE OPERATING. The posthole digger was designed for one-man operation from
the tractor seat. It is the responsibility of the operator to see that no one is within twenty
five feet (25’) of the digger when it is in operation.
- Operate only in daylight or good artificial light.
- Ensure digger is properly mounted, adjusted and in good operating condition.
- Ensure all safety shielding is properly installed.
- Remember, stabilizers should be used to prevent side swing.
