Husqvarna Construction Products has a policy of continuous product development. Husqvarna reserves the right to modify the design and appearance of products without prior notice and without further obligation introduce design modifications.

• DM 330 is an electric stand drill, intended for drilling holes in concrete, bricks and various stone materials.
• The drilling machine has a modular design and is easy to assemble.
• The machine is equipped with a water connection which can be rotated 180 degrees to facilitate work.
• DM 330 has three speed ranges for drill sizes up to 350 mm on the low speed version and 250 mm on the high speed version.
• The machine has a water-cooled gearbox with a pipe that runs through the spindle.
• The machine is equipped with LEDs which indicate the power output. This way you can always get maximum power output without damaging the machine.

The drilling machine is equipped with Softstart™, Smartstart™, Elgard™ and speed control.

SoftstartTM

Softstart™ is an electronic current limiter which provides a softer start. Maximum speed is reached about three seconds after the machine is turned on.

SmartstartTM

If the Smartstart™ button is pressed in the speed is reduced. In Smartstart™ mode the machine has less power until the button is pressed in again. These functions are of great use for creating a pilot hole for drilling.

ElgardTM

Elgard™ is an electronic overload protection. It considers factors such as rated input voltage and ambient temperature. This way you can always get maximum power output without damaging the machine.

If the motor is overloaded, the overload protection pulses the motor. Reduce the load and the motor returns to its normal speed. The overload protection disconnects the power, if the machine is subjected to heavy loads or if the drill bit jams.

Reset the machine by switching it off and then on again. If the drill bit jams, the mechanical slip clutch protects the gearbox before the overload protection disconnects the power.

Speed control

The speed control function provides the machine with a limited idling speed. This provides a more effective cooling of the machine at idle speed.

Ergonomics

The carrying handle makes it easy to carry/transport the machine and facilitates mounting it on the stand.

General safety precautions

WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Work area safety

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
• 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.

Electrical safety

WARNING! There is always a risk of shocks from electrically powered machines. Avoid unfavourable weather conditions and body contact with lightning conductors and metal objects. Always follow the instructions in the Operator's manual to avoid damage.

WARNING! Do not wash the machine with water, as water can enter the electrical system or the engine and cause damage to the machine or short circuit.

• The machine should be connected to an earthed outlet socket.
• Check that the mains voltage corresponds with that stated on the rating plate on the machine.
• Check that the cord and extension cord are intact and in good condition. Use an extension cord intended for outdoor use.
• Never use the machine if any cable or plug is damaged, but hand it in to an authorized service workshop for repair.

• Do not use an extension cord while it is rolled up to avoid overheating.

• Never carry the machine by means of the cord and never pull out the plug by pulling the cord.

• Keep all cords and extension cords away from water, oil and sharp edges. Make sure the cord is not pinched in doors, fences or the like. Otherwise it can cause the object to become live.
• The water system cools the drill bit with clean water. The power tool should not be exposed to more moisture than what is provided by the water system. Make sure that no drill slurry enters the machine.
• Do not expose the power tool to rain. Water entering a power tool will increase the risk of electric shock.
