SAFETY INSTRUCTIONS

General safety precautions
This information is never a substitute for professional skills and experience.
This section describes basic safety directions for using the machine.

• Please read the operator’s manual carefully and make sure you understand the instructions before using the machine.
• Keep in mind that it is you, the operator that is responsible for not exposing people or their property to accidents or hazards.
• The machine must be kept clean. Signs and stickers must be fully legible.

Work area safety

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• People and animals can distract you causing you to lose control of the machine. For this reason, always remain concentrated and focused on the task.
• Do not use the machine in bad weather, such as dense fog, heavy rain, strong wind, intense cold, etc. Working in bad weather is tiring and can lead to dangerous conditions, e.g. slippery surfaces.
• Never start to work with the machine before the working area is clear and you have a firm foothold. Look out for any obstacles with unexpected movement. Ensure that no material can become loose and fall, causing injury when operating the machine.
• Always check the rear side of the surface where the drill bit will emerge when drilling right through. Secure and cordon off the area and make sure that no one can be injured or material damaged.

Use and care

• Wear personal protective equipment. See instructions under the heading ”Personal protective equipment”.
• Never use the machine if you are tired, if you have drunk alcohol, or if you are taking medication that could affect your vision, your judgement or your co-ordination.
• Check that no tools or other objects have been left lying on the machine.
• Never allow anyone else to use the machine without first ensuring that they have understood the contents of the operator’s manual.
• Be careful as clothing, long hair, and jeweler can get caught in moving parts.
• Remain at a distance from the drill bit when the motor is running.
• Make sure that no pipes or electrical cables are routed in the area to be drilled.
• Never leave the machine unsupervised with the motor running.
• Never work alone, always ensure there is another person close at hand. Apart from being able to receive help to assemble the machine, you can also get help if an accident should occur.
• Never use a machine that is faulty. Carry out the checks, maintenance and service instructions described in this manual. Some maintenance and service measures must be carried out by trained and qualified specialists. See instructions under the heading Maintenance.
• Never use a machine that has been modified in any way from its original specification.
• Do not overload the machine. Overloading can damage the machine.
• Keep tools sharp and clean in order to enable safer work.
• Keep all parts in good working order and ensure that all fixtures are properly tightened.
• Keep the hydraulic hoses and couplings free from dirt. Do not use hoses that are distorted, worn or damaged.
• Check that all couplings, connections and hydraulic hoses are in full working order. Check that the hoses are connected correctly to the machine and that the hydraulic couplings lock as intended before pressurising the hydraulic system. The couplings are locked by turning the outer sleeve on the female coupling so that the slot moves away from the ball.
• Check the machine, couplings and hydraulic hoses daily for leakage. A rupture or leak can cause a ”hydraulic fluid injection” in the body or result in other serious physical injury. Do not check for leakage with your hands. Contact with the leak can result in serious personal injury caused by the high pressure in the hydraulic system.
• Make sure the rotation control is set to OFF (0) before connecting the hydraulic hoses.
• Never disconnect the hydraulic hoses without first shutting off and disconnecting the hydraulic unit and ensuring the motors have stopped completely.
• Inspection and/or maintenance should be carried out with the hydraulic hoses disconnected.
• Do not exceed the specified hydraulic fluid flow or pressure for the tool being used. Excessive pressure or flow can result in rupturing.
• Observe care when lifting. You are handling heavy parts, which implies the risk of pinch injuries or other injuries.

Transport and storage

• Secure the equipment during transportation in order to avoid transport damage and accidents.
• Do not store or transport the drilling machine with the drill bit fitted in order to protect your drilling machine and drill bits from damage.
• Store the drilling machine in a lockable area so that it is out of reach of children and unauthorised persons.
• Store the drilling machine and stand in dry and frost free conditions.

SAFETY INSTRUCTIONS

Work safety

• The machine has a very high torque. This demands good concentration during work, as serious personal injuries can occur if the drill bit suddenly jams.
• Keep your hands at a safe distance from the drill spindle and drill bit when the machine is running.
• Keep an eye open for oil or water leakage. If water or oil trickles out from the leakage hole on the top of the pinion neck, the seals must be replaced.

Stand drilling

• The machine is intended for stand mounted drilling.
• Make sure that the stand is secured correctly.
• Make sure that the drilling machine is secured correctly in the stand.
• Take extra care during the start of the drilling when the drill bit is placed against the work piece. The drill bit does not have any guidance. This increases the risk for it starting to drift. This puts load onto the stand, with the risk of its fixing breaking loose.
• Be careful if the drill bit gets caught in the work piece. This puts load onto the stand, with the risk of its fixing breaking loose. This will cause the stand to start rotating around the drill bit.
• Make sure that the cooling water does not come into contact with an electrical cabinet or similar.

ASSEMBLING AND ADJUSTMENTS

Connect the power unit

• The couplings should be wiped clean to reduce the risk of leakage before the hoses are fitted.
• The couplings are locked by turning the outer sleeve on the female coupling so that the slot moves away from the ball.

Connect the water cooling

• Connect the water hose to the incoming water connector.

Fitting the drill bit

• Apply water-resistant grease to the thread of the drill bit.
• Attach the drill bit using the open-ended spanners.
• Before the machine is started, carefully check that the new bit is firmly attached.

Speed

• Set the right speed for the present diameter of the drill bit. See instructions in the section “Technical data”.

• The hydraulic motor speed can be set in three positions. The motor speed can be changed during operation.

• The mechanical gearbox has two gears.

NOTICE! Changing mechanical gear may only be done when the machine is switched off. Otherwise there is a risk of damaging the gearbox.

STARTING AND STOPPING
