OPERATOR WARNINGS
Your first consideration, when servicing your TE260,
must be your personal protection and that of others.
Correct servicing is a matter of being completely
familiar with your machine and the job it is intended to
do. Carefully read and understand the warnings listed
below, and most of all remember to apply good common
sense at all times.
1. DO NOT OPERATE DRILLING CONTROLS
UNLESS YOU ARE THOROUGHLY FAMILIAR
WITH FUNCTIONS.
2. DO NOT OPERATE THE TE260 HYDRAULIC
DRILL UNLESS ACCUMULATORS HAVE BEEN
CHARGED.
3. WEAR A PROTECTIVE HELMET AND EYE
PROTECTION WHEN OPERATING OR NEAR THE
DRILL CARRIER.
4. WEAR NOISE-REDUCING EAR PROTECTION
WHEN NEAR THE MACHINE FOR EXTENDED
PERIODS WHILE THE MACHINE IS RUNNING.
5. DO NOT ATTEMPT LUBRICATION OR
SERVICE WHILE MACHINE IS RUNNING.
6. BE SURE THE HYDRAULIC AND PNEUMATIC
SYSTEMS ARE NOT PRESSURIZED BEFORE
LOOSENING ANY CONNECTIONS OR PARTS.
7. REMOVE DRILLSTEEL AND LOWER THE
DRILL TO CENTRALIZE BEFORE TRAMMING.
8. BEFORE STARTING THE ENGINE, BE SURE
ALL HYDRAULIC CONTROLS ON THE DRILL
AND CARRIER ARE IN THE OFF OR NEUTRAL
POSITION.
9. BE SURE ALL HYDRAULIC HOSE
CONNECTIONS ARE TIGHT, AND HOSE
RETAINERS IN PLACE.
10. KEEP ALL PERSONNEL AWAY FROM THE
HOLE WHILE DRILLING IS IN PROGRESS.
11. DO NOT REDRILL ANY BLAST HOLE.
12. DO NOT STRIKE THE DRILL STEEL TO
DISLODGE IT WHILE THE DRILL IS OPERATING.
FRAGMENTATION OF THE DRILL STEEL MAY
RESULT.
13. BE SURE THE DRILL STEEL COUPLING DOES
NOT UNTHREAD TOTALLY FROM BOTH DRILL
STEEL AND SHANK.
14. IF BIT BECOMES PLUGGED, DETATCH BIT FROM
STEEL TO REMOVE OBSTRUCTION. NEVER
HAMMER ON BIT OR STEEL. FRAGMENTATION CAN
PRODUCE SERIOUS INJURY.
15. BEFORE ATTEMPTING TO REMOVE DRILL FROM
FEED, RELIEVE STANDING PRESSURE.
16. USE CAUTION WHEN CHECKING FOR LEAKS.
FLUID UNDER PRESSURE MAY PENETRATE THE
SKIN.
17. DRILL AND FEED MUST BE IN THE HORIZONTAL
POSITION FOR DISASSEMBLY.
18. IF RIG IS TO BE OPERATED WITH DRILL
DISMOUNTED, SECURE AND CAP ALL LOOSE
FITTINGS AND CONNECTIONS.
19. DO NOT REMOVE THE ACCUMULATOR COVERS
BEFORE COMPLETELY BLEEDING OFF THE GAS
CHARGE IN THE ACCUMULATOR.
20. THOROUGHLY TEST ALL REPAIRS BEFORE
PUTTING EQUIPMENT INTO SERVICE.
Section 2 Page 2-1
EQUIPMENT CAUTIONS
The following are good practices to observe
for protecting the equipment and drills from
damage, and to provide maximum life for the
machine:
1. MAINTENANCE OF TE260 HAMMER,
BEARINGS, ACCUMULATORS, VALVE
ASSEMBLY OR STROKE CONTROL MUST BE
PERFORMED IN A CLEAN SHELTERED AREA.
THE ONE OVERRIDING RULE IN MAINTAINING
HYDRAULIC EQUIPMENT IS CLEANLINESS.
PREVENTION OF CONTAMINATION IN
HYDRAULIC FLUIDS IS THE MOST IMPORTANT
FACTOR IN MAINTAINING HIGH PERFORMANCE
IN TODAYS HYDRAULIC EQUIPMENT. AT ONE
TIME WHEN MACHINES OPERATED AT LOW
SPEEDS AND LOW TEMPERATURES
CLEANLINESS WAS A VIRTUE, TODAY IT IS A
NECESSITY.
2. KEEP THE DRILL LUBRICATED. APPLY
GREASE DAILY, OR WHEN INDICATED (MORE
OFTEN IN HOT CLIMATES) TO THE GREASE
FITTINGS AT THE CHUCK END OF THE DRILL.
3. PERIODICALLY INSPECT HOSE RETAINERS
AND HOSES FOR INDICATION OF WEAR,
LOOSENESS, CRACKING, OR FRAYING.
4. FREQUENTLY CHECK ALL NUTS, BOLTS,
AND ADJUSTMENTS FOR PROPER TENSION.
5. BE SURE THE HYDRAULIC RESERVOIR IS
ALWAYS FILLED TO THE RECOMMENDED
LEVEL WITH THE PROPER TYPE HYDRAULIC
FLUID. DO NOT MIX TYPES OF FLUID.
6. KEEP ALL BITS SHARP AND PERIODICALLY
CHECK FOR BROKEN OR LOOSE CARBIDES.
7. EXCESSIVELY WORN THREADS ON THE
DRILL STRING CAN CAUSE PREMATURE WEAR
AND BREAKAGE OF NEW PARTS MATED WITH
THE STRING.
8. DO NOT OPERATE THE DRILL ROTATION AND
FEED AT FULL THROTTLE UNTIL SURE OF ROCK
CONDITIONS. OVER FEEDING AND OVER ROTATION
CAN CAUSE BREAKAGE OF DRILL ROTATION
PARTS AND THE DRILL STRING
9. FREE OSCILLATION (DRY FIRING) OF DRILL
WILL RESULT IN PREMATURE WEAR OR FAILURE
OF CYLINDER AND HAMMER SEALS.
10. BEFORE REMOVING ANY LINES OR HOSES, TAG
EACH TO FACILITATE REASSEMBLY.
11. CAP OR PLUG ALL HYDRAULIC AND
PNEUMATIC CONNECTIONS AFTER DISASSEMBLY
TO PREVENT CONTAMINATION OF THE SYSTEM.
12. CLEAN THE EXTERIOR OF ALL PARTS AND
HOSE CONNECTIONS BEFORE REMOVING.
13. DO NOT OPPERATE THE TE260 HYDRAULIC
DRILL UNTIL ACCUMULATORS HAVE BEEN
CHARGED.
14. BEFORE REASSEMBLING HYDRAULIC
COMPONENTS, CLEAN ALL METAL PARTS IN A
NON-FLAMMABLE CLEANING FLUID.
15. THOROUGH CHECKS MUST BE MADE OF ALL
REASSEMBLIES TO BE SURE THEY ARE
ASSEMBLED PROPERLY ACCORDING TO
INSTRUCTIONS. DO NOT DRILL UNTIL ALL CHECKS
HAVE BEEN MADE.
