OPERATION
4
Correct operating position is with the two handles
bellow waist level, which will ensure full control of
the digger can be maintained.
Have your left foot slightly further forward than your
right foot to enable the frame near the safety bar to
rest against your left thigh. Always firmly grip the
handles with two hands when operating the unit.
DO NOT operate with either
one or two handles above waist
level.
The safety bar is designed to prevent
excessive rotation of the auger when the bit
is jammed, enabling the user to maintain
balance during operation.

blanching of fingers, usually apparent upon exposure to cold. Hereditary factors, exposure to
cold and dampness, diet, smoking and work practices are all thought to contribute the
development of these symptoms. It is presently unknownwhat,if any, vibrations or extent of
exposure may contribute to the condition. There are measures that can be taken by the
