Under most conditions it is best to run the auger slowly. In most cases 30 to
40 RPM auger speed seems to give the best drill rate and wear on the teeth.
This would be 100 to 120 RPM PTO speed.
To improve drill rate, occasionally relieve the down pressure on the auger.
This seems to let the teeth "take a bite".
DRILLING LARGE CHUNK ROCK---This is probably the toughest of all drilling condi-
tions, and certainly can be the most destructive to both the equipment and
drilling elements. Since the teeth will encounter frequent severe impacts, an
experienced operator must use care and get the feel of allowing the auger to
find its way down through the rocks.
RAD series augers give the best service in most cases under these conditions.
PUFF DRILL---This is a solid steel shaft equipped with a special carbide cutting
head for drilling 2" holes in rock or concrete. We call it the puff drill be-
cause it will build up down hole pressure and the cuttings will blow out of the
hole. FOR BEST RESULTS OBSERVE THE FOLLOWING:
1)
Run PTO at 100 to 200 RPM. Excessive speed can cause cutting head to over-
heat.
2)
Relieve the down pressure on the cutting head frequently. TOO MUCH
CONSTANT DOWN PRESSURE MAY CAUSE PARTICLES TO BE BLOWN AT A FORCE
SUFFICIENT TO CAUSE INJURY TO PERSONS OR EQUIPMENT. Too much down pressure
may also cause the cutting head to over heat or cause excessive wear.
3)
Very abrasive rock may cause excessive wear and shorten the life of the
cutting head.
4)
ALWAYS WEAR GOGGLES WHEN OPERATING THE PUFF. ALWAYS REQUIRE WORKERS OR
BYSTANDERS, IN THE AREA, TO WEAR GOGGLES WHEN THE PUFF IS BEING OPERATED.
PARTICLES OF ROCK CAN BE BLOWN 20 FEET OR MORE, WITH ENOUGH FORCE TO CAUSE
INJURY TO EYES OR OTHER BODY PARTS. KEEP ALL BYSTANDERS AT LEAST 20 FEET
AWAY FROM MACHINE WHEN IN OPERATION.
MAINTENANCE
CHECK AND TIGHTEN ALL BOLTS.
LUBRICATE, following previous instructions found elsewhere.
DAILY MAINTENANCE:
⇒
CHECK AND TIGHTEN ALL BOLTS
⇒
INSPECT AUGERS FOR UNUSUAL WEAR.
RENEW HARDFACED AREAS WHEN WEAR IS NOTICED.
⇒
REPLACE WORN BITS AND CUTTING TEETH.
⇒
INSPECT ALL SAFETY SHIELDS. REPAIR OR REPLACE IF NOT
IN PROPER WORKING ORDER.
⇒
LUBRICATE UNIVERSAL JOINTS AND DRIVELINE SHAFT.
⇒
LUBRICATE MAINFRAME TUBES AND CARRIAGE SLIDES.
INSPECT MACHINE REGULARLY:
Repair or replace any worn parts. Remember that earth boring can be hard work
for any machine. Under extreme conditions parts can wear or break. Using any
machine without proper maintenance of all parts can cause further damage to good
parts.
