3-3-3

OPEN When the oscillating lock lever is at [ON], the hydraulic connecting circuit is released during traveling or oscillating operation to set the oscillation of the right and left track frames to be possible. Because the right and left oscillating cylinders work together as a hydraulic connecting circuit, the right and left track frames oscillate in reverse directions and against each other, according to the unevenness of the ground. That increases stability when moving over unleveled ground.

4. Pilot Lamp This lamp lights up when the flushing air pressure or airflow drops or when feedback occurs because the rod rotation pressure increases. 5. Anti-Jamming Switch The anti-jamming switch has two functions; one is to prevent jamming where the bit and rod cannot be pulled out during the drilling. And the other is RP (Reverse Percussion), which is to pull out the rod by using the drifter impact force when the rod cannot be pulled out during drilling. Anti-Jamming Position Tilt the anti-Jamming switch forward, and the safety device (anti-jamming) operates. It automatically moves backward, if an abnormal condition is detected during drilling.

Drilling Control Box

3-5-5

If the following troubles are detected while the anti-jamming works, the drifter moves backward automatically. The flushing air pressure has dropped due to a trouble of the compressor. Flushing airflow has dropped due to stuffing of bit tip, etc. Rod rotation pressure has increased abnormally due to thrust up to the fracture zone or a solid

zone. Position RP (If Equipped) RP (Reverse Percussion) uses drifter impact force to pull out the rod when the rod cannot be pulled out during drilling. ★ RP (Reverse Percussion) is installed as an option when the machine is delivered from the factory. The RP (Reverse Percussion) is activated by the following procedure. 1. Tilt the anti-jamming switch (1) backward. 2. Push the feed lever (2) one step forward and set the feed

lever (2) to normal feed position. 3. Pull the impact lever (3) backward fully. The drifter

activates strong impact and the rod is pulled out. ★ The RP (Reverse Percussion) is automatically stopped

after 20 seconds. 4. When the RP (Reverse Percussion) needs repeated use,

temporarily stop impact and then pull the impact lever (3) again.

Continuous operation of the RP function not only leads to increased oil temperature and degradation of the drifter function, but also to machine breakdown. Avoid the continuous use of the RP function, as much as possible.

1. Air Flow Adjusting Lever This is also used as the cooler main switch. Set this lever at OFF, and the cooler will stop. The airflow can be adjusted in three steps. 2. Temperature Adjusting Lever This adjusts the temperature without step when the cooler is used. As moving the lever to COOL, the temperature is lowered. 3. Blow Out Port The air-blow outlet is mounted at the rear of the cabin. In the rear air blow outlet, operating the louvers changes the blow direction.

It is said that the healthiest cab temperature is about 5 - 6°C different from the open air temperature. It is not healthy to lower the temperature excessively or blow cold air on your body for a long time. Take the greatest care of temperature adjustment. Inside the cab may become dry because of the dehumidifying effect of the cooler. When the air-conditioner is operated, open the door about once an hour for ventilation. If inside the cab is dry, you might get pain in your eyes with cigarette smoke. If you smoke, open the window slightly for ventilation.

Handling during the Season In order to optimize the air-conditioning in the season, supply the cooling refrigerant: do check and maintenance. ★ To check the cooling refrigerant (gas), refer to 14.1 “When Required”. If the outside air enters the cabin, the cooling effect is not sufficient. Close the door or window

correctly. If the hot water of the heater circulates, the hot air hinders the cooling effect. Close the heater

cock correctly. ★ For heater cock, refer to 3.7.2 “Heater”.

Don’t keep the temperature at [HIGH/COOL]. If the high speed running continues set the temperature at LOW and the airflow at HIGH.

Handling in the Off-Season

If the air-conditioner is left for a long time with cooling refrigerant (gas) leaking, it might cause corrosion in the system. During the off-season, operate the air-conditioner for 5 - 6 minutes twice of three times a month will prevent the leakage of cooling refrigerant (gas) from the compressor sealing section.

New refrigerant (gas) R134a is tasteless, odorless, and harmless in the open air. However, if its liquid should have attached to your eyes or hands, you may lose your sight or you may be frostbitten. Never loosen any parts in the refrigerant (gas) circuit. For the supply of cooling refrigerant (gas) and checking and maintenance of the air-conditioner, ask your nearest distributor.

3.8 Handling of Fire Extinguisher The fire extinguisher in the machine is effective for the following: General Fire: fiber, paper and wood fires. Oil Fire: Diesel and other such oil fires. Electric Fire: Fire in electrical equipment with a risk of shock.

Precautions in Extinguishing Fire

The forcible use might increase the fire. It may not be possible to use the extinguisher to deal with a large fire or to use the extinguisher fast enough. The fire extinguishing should be from the windward so that gases are not inhaled. Tilting the extinguisher reduces its efficiency. Keep it as straight upright as possible. The fire extinguishing liquid is electric conductive. In order to prevent a short circuit or electric

shock; turn off the power when fighting fire electrical equipment. In fire fighting, approach the fire gradually keeping back 3 m after the fire is reduced. When fighting fire always keep open an escape route.

Drilling Precautions Beware with Blow Up of Cuttings

Check if cuttings are blows up by means of flushing air during drilling. If the blowhole at the bit tip is stuffed, the flushing air pressure is increased. If the blowout of the flushing air becomes weak, cuttings cannot be discharged normally to easily result in hole stuffing and jamming. ★ When the anti-jamming switch is anti-jamming position, the drifter moves backward automatically

when the flushing air pressure has increased, or the airflow has dropped due to stuffing of bit tip. Clean the Drilling Hole

If the cuttings cannot be discharged normally or the flushing air pressure increases, stop the impact and move the drifter up and down 2 – 3 times to clean the hole before re-starting drilling. ★ When the anti-jamming switch is set to anti-jamming position, the drifter is automatically stopped

moving forward if the rotation pressure is excessively increased. Beware of Spring Water

If dirty water is collected, the filter element in the dust collector may be clogged and dust collection degraded. If spring water comes out during drilling, tilt the dust collector switch backward and stop the dust collector operation.

5.2 Towing Don't tow the machine except where it can't move under its own power, due to breakdown of the drive motor or malfunction of the hydraulic system. If it can’t move, release the parking brake before starting its towing. When the machine is towed, take care of the following: Tow the machine with it set to "traveling posture”. Movement of a towed machine should only be for checking or maintenance.

Do not tow the machine more than 100m. If a longer distance is required, transport it on a vehicle such as a trailer.

Tow the machine at 2km/h or less, otherwise the drive motor might seize. Use a tow wire rope of 1.5 times or more of the strength needed to tow a vehicle of the mass of

the machine to be towed. Do not use a twisted or kinked wire rope. Do not use a chain to tow the machine because a link might break. The size of the tractor should be equivalent to or larger than the machine to be towed. Move and set the wire rope so that the coupling section of the tractor is aligned with the

attachment to the machine. Before towing, make sure there is nobody between the tractor and the machine. If the tractor moves suddenly the wire rope might break.

Operate the tractor slowly and at a steady speed. Do not tow the machine on sloping ground because the machine might run away under its own

mass.

Incorrect towing of the machine that can’t move under its own power is very dangerous and might cause accidents resulting in injury or death. When the machine is to be towed, comply with the following precautions.

DANGER

For releasing of the parking brake, ask your nearest distributor.

11. Fuels and Lubricants 11.1 Emergency Measures First Aid If fuel or lubricant accidentally splashed in your eyes, flush eyes with water for 15 minutes.

Get medical attention immediately. If it gets on your skin, wash it with soap and water. If you inhale it, go out into fresh air and keep warm with your body wrapped in a blanket.

Keep quiets and get medical attention immediately. If you drink it, do not force yourself to vomit. Get medical attention immediately.

If inside of your mouth is contaminated, wash with large amount of water. Treatment for Leakage

If fuel or lubricant leaks, do not send it into the sewage system or river, so that secondary disaster or environmental pollution is not caused. Find the leakage point and stop leaking. Prepare such fire extinguishing equipment as a fire extinguisher. Do not allow any burning cigarette, spark or naked flame close to the leaking point. Use protective gear with good conductivity in order not to generate static electricity. If required, wear a gas mask. If the leakage is small, dry it with soil, saw dust or a rag. If the leakage is large, contain the flow by surrounding it with soil. Cover the liquid's surface with

bubble fire extinguishing liquid and retrieve it in an empty container. If leakage occurs indoors, ventilate the room by opening windows and doors.

Measures in Fire Wear protective gear for fire extinguishing, such as a gas mask and protective gloves and

extinguish the fire from the windward. Stop everybody except for the fire fighters from coming near the fire. Fire extinguishing with bubble fire extinguishing liquid and intercepting air is effective.

Do not use water because it might spread the fire. Sprinkle water around the origin of a fire to cool the spot and prevent the spread of a fire.

Careless handling of fuels and lubricants might cause not only environmental destruction, but also accident resulting in injury or death. Take the greatest care in handling fuels and lubricants.

and screw the suction hose (2) into the adapter (1). 9. Close the engine cover.

Supply the hydraulic oil after stopping the engine and making sure that the hydraulic tank has cooled down to normal temperature. When the stop valve handle (3) is set to OPEN the hydraulic oil might flow back. After oiling, always set the handle (3) to CLOSE. The hydraulic oil is flammable. Wipe off spilled oil carefully.

12. Coolant Many engine failures are related to the cooling system. Maintenance of the engine coolant is important to the engine life and to the performance. Water

Use soft water with low impurity content as the coolant. Do no use hard tap water or salt softened tap water in engine cooling systems. Distilled water or deionized water is recommended for use in engine cooling system Antifreeze.

Antifreeze must be used in any climate for both freeze and boiling point protection. Furukawa recommends a 1:1 mixture of water/ethylene glycol base antifreeze. The mixture ratio of water/antifreeze when the factory is shipped is 1:1. ★ For more detailed description of coolant, refer to Operation and Maintenance Manual of

Caterpillar C7 Engine.

Antifreeze is poisonous; if ingested, it can cause serious injury or death. Induce vomiting and get emergency medical attention immediately. If antifreeze accidentally splashed in your eyes, flush eyes with water for 15 minutes. Get medical attention immediately. If it gets on your skin, wash it with water. When storing antifreeze, be sure to keep it in a clearly marked container with tight closing lid. Always keep antifreeze out of the reach of children.
