>>>> BEFORE STARTING ENGINE <<<<
FILLING ENGINE CRANKCASE WITH OIL
Tools Required:
1 each, small, clean funnel with a flexible extension spout
Fill engine crankcase with oil on level working platform of appropriate size and
height. As an alternative, transmission driveshaft can be securely mounted in
suitable bench vise.
1.
Wipe any dust/dirt from crankcase dipstick/filler plug area. Remove
dipstick/filler plug.
2.
Using funnel, add oil to engine crankcase. For proper classifications
and/or amount, consult material supplied by engine manufacturer for
specific information.
3.
Replace dipstick/filler plug and tighten. Wipe off any excess spilled oil.
Properly dispose of spilled oil/rags per international and local regulations.
4.
Consult material supplied by engine manufacturer for other service
related information including oil change interval. DO NOT operate Hole
Digger unless proper oil level is maintained. Engine damage can result.
FILLING ENGINE FUEL TANK
Tools Required:
1 each, small, clean funnel.
Hole Digger uses a 4-Stroke engine. DO NOT mix engine oil with gasoline.
Damage to engine can result. BEFORE operating Hole Digger refer to
MACHINE SPECIFICATIONS section in this manual and engine manufacturer
supplied materials for information regarding engine fuel, fueling and lubrication
requirements.
1.
Use extreme caution handling gasoline. Always use UN marked,
European ADR regulation approved container for storage and
transportation of fuel. Shut engine off and allow to cool before fueling.
Never remove fuel tank filler cap or fill fuel tank while engine is running.
Never operate engine without fuel tank filler cap. Select bare ground for
fueling and move at least 3.05 M (10 feet) from fueling spot before
starting engine.
2.
Carefully clean filler cap and surrounding area to prevent dirt/debris
falling into fuel tank.
3.
Fill fuel tank with fresh, clean, unleaded automotive gasoline. Leaded
"regular" grade gasoline is acceptable substitute. DO NOT USE
GASOLINE CONTAINING METHANOL (WOOD ALCOLHOL). Gasoline
containing maximum 10 percent ethanol/grain alcohol (sometimes
referred to as Gasohol) may be used but requires special care when
storing engine for extended periods.
NOTE: DO NOT use gasoline left over from previous season for easier engine
start-up and prevent poor engine performance.
4.
DO NOT completely fill tank. Fill tank to within 7mm (1/4 inch) to 13 mm
(1/2 inch) of tank top to allow for fuel expansion. Replace filler cap. Wipe
any fuel spillage and oil if leak is detected from engine and Hole Digger
BEFORE operating engine. DO NOT operate engine until oil leak is fixed
and fuel is wiped away. Properly dispose of any fuel or oil wiped from
machine/rags per international and local regulations. DO NOT allow fuel
or oil to get on clothing. Change clothes immediately if this happens.
7 APPLICATION THEORY & TECHNIQUES
The Hole Digger operates on principle of accessory augers attached to the
transmission drive shaft to rotate and dig holes in a variety of soil types. The
combination of auger diameter, blade, screw bit, soil type and down pressure
supplied by operator will affect the hole digging rate.
Hole digging process is directly controlled by:
1.
Soil type.
2.
Auger boring head design and diameter selected.
3.
When required, sufficient application and/or reduction of machine weight
and/or down force provided by operators to assist auger soil penetration.
4.
No two soil types are exactly alike, no two holes can be dug by exact
same method, overall operator feed rates vary. The hole digging process,
along with operator experience, skill and common sense, suggests hole
digging is a matter of trial and error and directly determines overall
success of the job application.
HOLE DIGGING TECHNIQUES
1.
Normal Hole Digger operation runs engine at full, governed speed
allowing centrifugal clutch to become firmly engaged. Technique
transmits more usable power to auger, increasing productivity and
reducing component wear. For any soil condition, allow auger to dig at
rate most comfortable to operators, but not cause centrifugal clutch to
overload and slip.
NOTE: Hole Digger is equipped with a centrifugal clutch assembly within the
transmission. The clutch assembly is designed to ALWAYS slip (NOT
DISENGAGE) when overloaded or if auger contacts buried obstruction. When
slipping, clutch still transmits a specific amount of torque to auger. Response
time for clutch to react to overload condition is directly proportional to rotational
speed. With higher rotational speeds (RPM) of clutch at time of overload, it
takes more time for clutch to react and actually slip.
2.
In general, pressing down on operator handle is not required to initiate
and/or sustain the digging process. In most moderate density soils, auger
dig rates will not cause centrifugal clutch to overload and slip. In most
soft, low density soils (sandy, etc.), it may be necessary to hold up on
operator handle to reduce auger dig rate due to tendency of any auger
design to cause centrifugal clutch to overload and slip. In most hard, high
density soils (hard clay, etc.), it may be necessary to press down on
operator handle to establish and maintain acceptable dig rates.
3.
Some soil conditions may require more power to dig than machine is
capable of delivering for a given auger diameter. To minimize problem,
apply suitable down force by operator and use augers with new screw
bits and blades. DO NOT use more than one operator to apply down
force.
4.
When digging in areas filled with known, buried obstructions such as tree
roots, rocks and other debris, operate Hole Digger at less than full (an
intermediate) speed for more rapid release of centrifugal clutch when
obstruction is encountered. This is an industry wide operating procedure.
5.
When digging in areas filled with small tree roots, small rocks or other
buried obstructions, allow auger blade to "chip away" at obstruction until
auger can pass by (by working object loose) or go through it (as in
penetrating tree roots). Technique usually involves holding up on operator
handle using minimal auger feed rate. Many times size and nature of
buried object will prevent auger from passing by or going through it.
Instead, remove buried object with shovel or other suitable tool and
proceed to dig to desired depth using Hole Digger.
6.
Some job applications may encounter buried obstructions too massive in
size or soil classifications too compacted for Hole Digger use. Another
type equipment of proper size may be required.
7.
In most soil conditions, the auger will retract with less effort if allowed to
rotate at slow speed. This procedure, however, will leave more loose soil
at bottom of hole. To minimize amount of loose soil remaining at bottom
of hole, stop rotation before retracting auger.
