Storage
Application: All 300 Series models.
Proper procedure for long term storage of the Hole
Digger will protect it against the affects of corrosion and
damage. If the Hole Digger is not to be operated for a
period of 30 days or more, proceed to store as follows:
1) Clean all accumulated dirt and grease from the Hole
Digger utilizing an appropriate solvent.
Observe all applicable safety precautions for the
solvent.
2) Follow the procedure as outlined in the material
supplied by the engine manufacturer detailing long
term storage of the engine.
3) Drain the transmission and refill with clean oil that is
suitable for use when the Hole Digger will be next
utilized.
4) Check all visible parts for wear, breakage or
damage. Order any part required to make the
necessary repair. This will avoid a needless delay
when operating the Hole Digger at next use.
5) Apply a light coat of protective grease to the
transmission driveshaft to prevent the formation of rust.
6) Do not store the Hole Digger connected to an auger.
