RGC ROCK DRILL, Инструкция по эксплуатации

3 OPERATION
3.1 BEFORE OPERATING THE ROCK DRILL
CAUTION:
THE HYDRAULIC ROCK DRILL CANNOT RECEIVE A REVERSE OIL FLOW WITHOUT
SUSTAINING SOME FORM OF DAMMAGE. USE OF A POWER SOURCE OTHER THAN AN
RGC POWER UNIT REQUIRES THAT THE MANUAL FOR THAT POWER SOURCE BE
CHECKED FOR PRESSURE AND TANK CONNECTIONS TO INSURE PROPER OIL FLOW
DIRECTION. ROCK DRILL WARRANTY MAY BE IN JEOPARDY IF CAUTION IS NOT
EXERCISED PRIOR TO CONNECTION OF TOOL.
1.
Read and fully understand the operating manual for the hydraulic power source being used.
2.
Every tool has a maximum operating flow and pressure, which, if exceeded, is a potential cause of damage to the tool
or hydraulic power source. Check the power supply’s flow and pressure output against the tool’s requirements.
3.
Use caution when refueling a gasoline driven hydraulic power source. Make sure the gas caps on the hydraulic power
source and fuel can are properly tightened. Move the hydraulic power source at least 10 feet from the fueling point
before starting the engine.
4.
Do not start drilling without first checking for live electrical wiring or utility/supply piping near the drill site, or
imbedded in the material to be drilled.
3.2 LOW AMBIENT AND OIL TEMPERATURE STARTUP (<32
°
F)
Oil temperatures can affect both power supply and tool performance. For ambient operating temperatures between 0-32
°
F,
RGC recommends a warm-up period relative to outside temperatures to insure proper performance levels.
Oil becomes more viscous or thick as the ambient temperature lowers, which slows down the system. It is necessary to
pre-heat the hydraulic oil in the power supply before use by proceeding as follows:
1.
Leave the equipment inside a heated facility before use if practical, but this is not always possible.
2.
At the job site, start the power supply and let the engine warm up for 5 minutes WITHOUT tool or hoses connected.
3.
Adjust throttle speed to full engine rpm, then SLOWLY turn flow valve to ON position. Allow unit to run for 5-7
minutes, then turn flow valve to OFF position. Return engine RPM to slow idle; then turn off engine. Connect tool
and hydraulic hoses as described in section 3.4. This procedure will labor the engine and generate the required heat in
the power supply oil.
4.
Taking the time to pre-heat the oil far exceeds the length of time it takes to get the system up to speed without pre-
heating, but this will provide the level of designed performance.
3.3 HIGH AMBIENT AND OIL TEMPERATURE STARTUP (>100
°
F)
Oil becomes less viscous or thinner as ambient temperature increases which causes the hydraulic oil to operate at an
elevated temperature. For ambient operating temperatures above 100
°
F (38
°
C), RGC recommends the following:
1.
Insure that the hydraulic fluid level is up in the power supply reservoir.
2.
Operate the tool at a reduced cycle time—10 minutes on, then 10 minutes off.

CONNECTION TO HYDRAULIC POWER SOURCE
1.
Before making any hydraulic connections, inspect all hoses for leaks and risks of rupture as follows:
