number and design configuration exists. Models 330H

When installing the auger and auger pin,
always place the Hole Digger with the engine
spark plug in the upward position to minimize
the potential for gravity to allow oil and/or
gasoline to enter into the combustion
chamber and create a hydraulic lock up. Such
an occurrence can result in property damage
and/or personnel injury.
The auger pin supplied with the Hole Digger
is designed to withstand the high stresses
encountered while digging. Use of any other
connecting device, including cap screws,
bolts, pins, etc., can result in damage to the
Hole Digger driveshaft and/or auger drive
hub. Improper connecting devices can cause
property damage and/or personal injury.
DO NOT CONNECT THE AUGER TO THE HOLE
DIGGER WITH THE ENGINE RUNNING. A
SUDDEN AND/OR UNEXPECTED CHANGE IN
THE ENGINE SPEED CAN RESULT IN
PROPERTY DAMAGE AND/OR PERSONAL
INJURY.
THE HOLE DIGGER IS DESIGNED FOR TWO
MAN OPERATION. USE BY ONLY ONE
OPERATOR OR BY MORE THAN TWO
OPERATORS WILL LEAD TO CONFUSION AND
LOSS OF CONTROL, RESULTING IN
PROPERTY DAMAGE AND/OR PERSONAL
INJURY. THE CONTROLS ARE DESIGNED FOR
ONE OPERATOR (CREW MEMBER) TO START
THE ENGINE AND OPERATE THE ENGINE
CHOKE CONTROL WHILE THE OTHER
OPERATOR (CREW CHIEF) HELPS MAINTAIN
MACHINE STABILITY AND REGULATES
ENGINE SPEED WITH THE TWIST GRIP
THROTTLE CONTROL.
STARTING THE ENGINE WITH THE AUGER

ACHED.
Application: 330H, 343H and 357H Hole Diggers
powered by the Honda GXV160 engine.
1) Grass and other overgrowth conditions will hamper
the digging characteristics of any earth auger by
becoming "clogged" around the auger teeth and screw
bit. Removal of such obstructions from the hole
location before attempting to dig will increase digging
efficiency and overall productivity.
2) Place the Hole Digger in a vertical orientation on the
desired hole location. The operators should position
themselves on firm footing.
3) The Crew Chief opens the fuel tank breather vent (if
so equipped) to its maximum set position. Failure to
properly open the breather vent will prevent the engine
from receiving a continuous supply of fuel.
4) The Crew Member opens the fuel tank ON/OFF
valve located under the fuel tank to the ON position.
