300 SERIES MAN HOLE DIGGER
FORM GOM12070702, VERSION 1.2
18
a) If equipped, the shorter (inner) screw is non
functional for this application.
b) The longer (outer) screw is factory set to prevent the
engine from operating in an overspeed configuration.
As set at the factory, the GXV160 engine will operate at
approximately 3800/3900 RPM no load. In a no load
configuration the engine is operating at maximum
governed speed without an earth auger attached to the
transmission driveshaft.
D
o not alter the position of the spring loaded
screw that regulates maximum engine speed.
An improper setting can result in excessive
engine speed leading to damage, substandard
digging performance and loss of operator
control that can result in property damage
and/or personal injury.
Before Starting the Engine
FILLING THE ENGINE CRANKCASE WITH OIL.
Application: 330H, 343H and 357H Hole
Diggers powered by the Honda GXV160
engine.
Tools Required:
1 each, small, adjustable wrench (if needed)
1 each, small, clean funnel with a flexible extension
spout
Filling the engine crankcase with oil will require a level
working platform of sufficient size and appropriate
height. As an alternative, the transmission driveshaft
can be securely in a suitable bench vise.
1) Wipe any dust or dirt from the crankcase
dipstick/filler plug area. Remove the dipstick/filler plug.
2) Using the funnel, add oil to the engine crankcase.
For proper classifications and/or amount, consult the
material supplied by the engine manufacturer for
specific information.
3) Relace the dipstick/filler plug and tighten. Wipe off
any excess spilled oil. Properly dispose of the spilled
oil.
4) Consult the material supplied by the engine
manufacturer for other service related information
including oil change interval.
DO NOT OPERATE THE HOLE DIGGER
UNLESS PROPER OIL LEVEL IS MAINTAINED.
IMPROPER OIL LEVEL CAN RESULT IN
PROPERTY DAMAGE AND/OR PERSONAL
INJURY. CONSULT THE MATERIAL SUPPLIED
BY THE SPECIFIC ENGINE MANUFACTURER
FOR INFORMATION RELATIVE TO PROPER
MAINTENANCE PROCEDURES.
FILLING THE HOLE DIGGER TRANSMISSION
WITH OIL.
Application: All 300 Series models.
T
ools Required:
1 each, small adjustable wrench.
1 each, small, clean funnel with a flexible
extension spout.
Filling the transmission with oil will require a level
working platform of sufficient size and appropriate
height. An alternative, the transmission driveshaft can
be securely mounted in a suitable bench vise.
1) Wipe any dust or dirt from the transmission oil
filler/level plug area. The oil filler/level plug is located on
the side of the transmission. Remove the plug with the
adjustable wrench.
2) Using the funnel, pour 1 US quart (0.94 liter) of
General Equipment Company transmission and Engine
Oil, PN 999-11, or a high grade, SAE 30 Detergent or
10W30 motor oil into the transmission though the oil
filler/level plug opening. Use only an oil marked with an
engine service classification SF, SG, or SH/CD. As a
general rule, the transmission is usually filled with the
same oil type and weight that is utilized in the
applicable 4-Cycle engine crankcase. FIGURE 9.
3) The transmission oil level is to be maintained at the
bottom of the oil filler/level plug hole. Allow any excess
oil to drain out of the transmission. This procedure
determines the correct oil level for the transmission.
Correct oil level is important to insure proper centrifugal
clutch operation. Maintaining the oil level too high will
cause excessive centrifugal clutch slippage and result
in high oil temperature. Excessive slippage and high oil
temperature will significantly reduce the service life of
the clutch assembly and affect the overall performance
of the Hole Digger.
