RGC ROCK DRILL, Инструкция по эксплуатации

Страница: 8 / 24

a. Inspect each hose for breaks, cracks, worn spots, bulges, chemical attack, kinks or any other damage. Never stop
any detected leak with your hand or fingers. Do not put your face close to suspected leaks. Hold a piece of
cardboard close to suspected leaks and then inspect the cardboard for signs of hydraulic oil.
b. Replace a damaged hose immediately. Never repair the hose.
WARNING:
LIQUID UNDER HIGH PRESSURE CAN PIERCE THE SKIN, CAUSING DEATH OR SERIOUS
INJURY. HOT LIQUID CAN CAUSE SERIOUS PERSONAL BURNS. IF AN INJURY OCCURS,
GET IMMEDIATE MEDICAL ATTENTION.
2. For connection, use a high pressure hose (inside diameter 1/2”) which, as a minimum, is designed for a working
pressure of 2500 psi. The breaker socket “P” is the oil inlet (pressure), and the socket “T” is the oil outlet (tank).
3.
The Rock Drill uses flush-face quick-release couplings, which are durable and very easy to clean. They are always
fitted such that the male part gives oil and the female part receives oil.
4.
The Rock Drill is designed for an oil flow of 5.3-6.6 gpm at 1400-2000 psi. Do NOT exceed this flow or pressure.
5.
If the oil flow cannot be adjusted by lowering the rpm, a flow divider must be installed. This will insure the Rock
Drill receives the correct oil flow and return excess oil back to the tank.
6.
To protect the Rock Drill from excessively high pressure, the pressure relief valve of the hydraulic power source must
be set at 2000 psi (140 bar). If this is not possible, installing a separate pressure relief valve set at 2000 psi (140 bar)
can be used to make the connection. If in doubt, contact your dealer.
7.
The backpressure (return line pressure) of the Rock Drill should be as low as possible and must not exceed 215 psi (15
bar) measured at the Rock Drill. If this pressure is exceeded, the Rock Drill will not rotate.
8.
The hydraulic power source must be fitted with a return line oil filter with a filter rating of 10 microns.

DRILLING PROCEDURE
1.
Check that the drill bit is intact and sharp and that the drill bit is pressed fully home in the nose part.
2. Clean the quick-release couplings if needed and connect the hose whips to the extension hoses from the power source.
3.
When lifting the Rock Drill to start the procedure, observe the following precautions:
a. Be sure of your footing.
b.
Keep hands off trigger to avoid accidental operation.
c.
Bend your knees and lift with your legs.
d.
Hold Rock Drill close to your body when lifting.
5. Place the Rock Drill vertically on the surface in which the hole is to be made and activate the trigger lever. Make sure
just enough feed force is being applied to have the Rock Drill run regularly. Activating the trigger partially when
starting provides a slow start for improved control.
6.
If different length drills are required to drill the same hole, the bits MUST be from the same ISO- series. Failure to do
this can cause binding of the bit resulting in tool and / or drill bit damage and personal injury. Use just enough feed
force to have the Rock Drill run regularly.
