10)
USING THE AUGER EXTENSION---Drill hole part way. Stop PTO, and shut off
tractor engine. Remove 3/4" bolt through auger and drive stem. Start trac-
tor engine and raise gearbox till hole in the top of the auger is aligned
with the hole in the drive stem. AGAIN SHUT OFF TRACTOR ENGINE. Replace
the bolt through the auger and drive stem, and continue drilling the hole
until desired depth is reached. To bring auger out of the ground, raise
gearbox to full height. SHUT OFF TRACTOR. Block auger up with a piece of
2x4 lumber, or other blocking material, to keep auger from falling back into
the hole. Remove bolt from auger and drive stem. Start tractor engine and
lower gearbox till holes in auger and drive stem are aligned. SHUT OFF
TRACTOR ENGINE and replace the bolt. Remove the block from auger and raise
to full raised position.
DANGER:
BE SAFE---DO NOT PERFORM ANY WORK AROUND MACHINE
WITH TRACTOR ENGINE RUNNING. Serious in-
jury or death could be the result if body
parts such as hands or feet are caught in
turning machine elements, or under the
force of hydraulic pressure.
When using the extension, dirt or other debris may accu-
mulate in the auger tube, therefore, frequently remove the
drive stem from the auger tube and clean it out. If dirt is
allowed to become impacted, the drive stem will be prevented
from going to the bottom of the tube and the holes will not align.
11)
KEEP MAIN FRAME SLOTTED TUBES CLEAN---and free of dirt and other debris.
Occasionally, clean tubes with a high pressure washer, or a swab and sol-
vent. Oil inside of tubes and gearbox carriage slide tubes liberally with
motor oil. DO NOT USE GREASE.
DRILLING HOLES IN DIRT---SSA series augers are equipped with cast steel replace-
able teeth boring heads, and are designed to drill holes in hard dirt, stony
dirt, soft dirt, and even some soft solid rock. Some suggestions follow:
Adjust relief valve to lowest setting which will accomplish your job.
When digging in soft dirt, or where tree roots are present, keep your hand on
the hydraulic valve and lower auger in increments a little at a time, to avoid
"corkscrewing" the auger and risk getting it stuck.
If you experience excessive tooth breakage when digging stony soil, try using
5T30 spike teeth in all the pockets.
For digging in abrasive soils, hardfaced teeth are available.
When drilling abrasive frozen soils or soft solid rock, 1335 carbide insert
teeth may work best.
DRILLING SOLID ROCK---Obviously, there are many variables in drilling solid
rock. Hardness of the rock, amount of down pressure available, size of the au-
ger, speed (RPM) of the auger, are a few of the things that will affect the
drill rate, or even the feasibility of being able to drill any specific solid
rock. This can only be determined on the site to be drilled. Although the
BELLTEC drilling machine is successfully drilling solid rock in many parts of
the country, we cannot in any way guarantee results at every location.
Rock can also be highly abrasive, causing excessive tooth wear. Of course
BELLTEC has no control over these conditions. Many users are getting 100 or
more holes before replacing any teeth. On the other hand some rock will wear
out teeth in just a few holes. Many operators of trenchers and commercial
drilling machines experience these same results from similar conditions. The
SRA, THC, or RAD series augers are usually best for drilling solid rock.
