EQUIPMENT CLEANLINESS
One of the most important procedures in any maintenance program should be to make sure it is kept clean, for
not only will it look better, it will run better too. Washing metal surfaces frequently, and keeping it painted will
prevent rusting and corrosion and it is much easier to detect cracks, bends of other damage that may be hidden
under layers of dirt and grime. The digger should, therefore, be washed and cleaned thoroughly at least once
each week during normal operation. The Earth Auger is designed for service under the most rugged conditions
and will require a minimum amount of maintenance to assure its dependable operation for many years. Most
owners have found that if a good tool is properly serviced, it will more than properly serve its owner.

HYDRAULIC SYSTEM
There is a 10 Micron Filter on the return line mounted to the side of the oil reservoir. The filter element should
be changed after the first 8 hours of operation and every 200 hours. A 100 mesh suction strainer located inside
the oil reservoir should be removed and cleaned at 100 hour intervals. The strainer can be removed by lifting
out attached spring loaded handle inside oil reservoir. The strainer can be cleaned with a solvent and dried with
compressed air. After cleaning, inspect the strainer carefully for damage. If damaged, replace. Check Fluid
level frequently with dipstick. Add SAE 10 grade anti-wear type hydraulic oil with Foam depressant, rust and
oxidation inhibitors, meeting performance classifications, OE/HDO MIL-L-2104. Added oil should be strained
through 100 mesh strainer, CLEANLINESS IS OF UTMOST IMPORTANCE.
CAUTION
If filter warning light comes on, SHUT DOWN MACHINE AS
SOON AS IT IS POSSIBLE TO DO SO SAFELY, REPLACE
AUTIO ELEMENTS.
REFER TO TROUBLE SHOOTING
CHART.
NOTE:
If hydraulic pump needs to be removed or replaced, an
auxiliary plug is provided to prevent loss of oil from
reservoir. Lift out spring loaded handle attached to strainer
and insert plug with attached handle in its place. Plug with
handle is attached inside oil reservoir to top with chain.
