Safety instructions
Read all precautions before operating the device and keep them for future reference.
Follow the operating instructions strictly; failures in the compliance with these safety precautions and instructions can cause electric shock, fire and/or heavy injuries.
Keep your working area clean and well illuminated. Untidiness or badly illuminated working
spaces can cause accidents and serious injuries.
Do not work in explosive areas with the electric tool, where there are flammable liquids, gases
or dusts.
Keep children and other people away from the electric tool while using it. Being distracted, can
cause loss of control over the device.
Always pay attention to what you are doing and be aware at all time while using the electric
tool. Do not use the electric tool when you are tired or under the influence of drugs, alcohol or
medication. One moment of carelessness while using the tool can cause serious injuries.
Wear personal protective equipment and always wear protective glasses. Wearing personal
protective equipment like a dust mask, skid-proof shoes, a protection helmet or hearing protection reduces the risk of injuries.
Avoid an unintended start-up. Make sure that the electric tool is switched off before connecting
it to the electricity, picking it up or carrying it. When carrying the device with your fingers on
the switch or connecting it to the electricity before checking whether the power switch is activated can lead to serious accidents.
Remove adjusting tools or wrenches before switching on the electric tool. A tool or wrench
which is located on a moving part can cause serious injuries.
Avoid unnatural postures. Care for a safe and stable posture and keep your balance at anytime. Do not work on a ladder. Keeping your posture in mind will allow you to control the tool
better in case of unexpected situations.
Wear suitable clothing. Do not wear loose clothing or jewellery. Keep hair, clothing and gloves
away from moving parts. Otherwise they can be caught by moving parts.
Do not overload the device. Use the appropriate tool for your work. With the appropriate tool
you will work better and saver in the declared range of performance.
Do not use an electric tool with a damaged switch. An electric tool which cannot be switched
on or off is dangerous and must to be repaired before it is allowed to be used again.
Disconnect the plug from the socket before altering settings, exchanging equipment or when
storing the device. This safety measure avoids unintended starts of the electric tool.
Keep unused electric tools out of reach of children. Do not allow people to use the device who
are not familiar with it or have not thoroughly read and understood these instructions. Electric
tools are dangerous if they are used by inexperienced people.
Voltage: Please note that the power voltage should not be more than ± 5 % of the rated
voltage. Higher voltages however can cause irreparable damages.

Instruction for hand-held drills
Wear hearing protection when operating the device.
Use the additional handle included in the delivery.
Always hold the handle while operating the machine.
Application
The diamond drill, also called concrete drill, is a type of tool which can drill on RC, brick,
stone, rock, porcelain, and fireproof materials. The device enables drilling without dust, has a
high efficiency and allows for smooth holes in walls with an accurate size. It can be used in
many fields of installation (like installation of devices, water and electricity, gas, construction
works, quality checks, road tunnels, railroads, and bridges). The drilling range of this product
is 15–505 mm. The machine has an automatic coupling system, switch-off protection against
overload and is easy for transport – this all safe and reliable.
It has a continuous speed variation and a two speed gear shift for a speed-adjustable diamond
core drill. It can work with different sizes of core drill bits and it can drill holes on hard or soft
materials. The adjustable-speed engine provides a soft start, constant power, overload protection and a continuous speed variation function.
Shifting gear
In order to improve the efficiency, some machines are designed with a 2-speed gear shift: high
speed (H speed) and low speed (L speed). H speed is for drilling on soft material with a small
drill bit and L speed is for drilling on hard material with a large drill bit.
Shift when the machine stops or is nearly stopping.
Shift in place: If the spindle does not rotate or there is some noise after starting it up, the gear
may not shift in place. Turn off the machine immediately and then shift the gear to its proper
place. Rotate the spindle back and forth (easy to shift) at the same time until the shift is in
place.
Do not shift when the machine is full-speed operated, overloaded or stuck.

Safe operation
Please read the manual carefully before using the tool. This machine may only be used by
trained people.
Please check the voltage before start. The power voltage should not be more than ± 5 % of
the rated voltage. Higher voltages however can cause damage, e. g. an engine fire or electric
leakage.
Wear a helmet, insulating gloves and the right gear. Do not wear wide clothing or jewellery
and keep your hair away to avoid injuries.
This machine is designed for wet drill bits. Do not use any other bits and never increase the
engine load.
Make sure that no water enters the engine. Do not block the ventilation in case of an engine
fire.
Check the workplace before operation. Eliminate any dangers such as high voltage power
lines, gas piping, water pipes and other possible sources of danger.
Pay attention to the safety of the lower layer if the machine should drill holes through the floor.
Check the structure of the building before drilling any beam column.
Do not work in explosive areas in which there are flammable liquids, gases or dusts. Electric
tools generate sparks which can inflame the dust or vapours.
Make sure that you start to operate the drill machine without any load. Starting with load is
prohibited and may cause damages to the machine and users. Always repair possible damaged parts of the machine in case of dropping when working in a high place.
Use a high-quality three-core cable and make sure the cable is connected with ground. A
ground fault circuit interrupter is necessary.
Attention: The manufacturer does not assume any responsibility for caused accidents
due to the machine not being solid or fixed safety facilities are not in appropriate place.

Operation
Extension bolt fixation: Drill a hole by impact drill in the set position and screw the extension
bolt. Always make sure it is tight and fix the diamond drill machine on it. Adjust the four regu lating screws to keep the drill machine from swinging.
Support rod fixation: Determine the drilling location. Fix the supporting rod by adjusting the
length of the push rod and also adjust the fastening screws. Ensure that the drilling rig sub structure is at full contact. If you drill vertically do not swing.
Fix the drill bit and connect it to the power and water supply. Move the adjusting tools as
needed and switch on the drill when it is at no load. Check the drill bit and the sound and open
the water tap, if everything is fine. The machine can start to drill when the water flows from the
drill bit.
Take it slow at first. When the drill bit cuts in the wall you can change to normal speed. Slow
down the machine if it runs into steel.
The drill machine is equipped with mechanical and electronic protection. If the engine is run ning while the drill bit is not moving it means that the drill bit needs to be sharpened or the
feeding speed is too fast. In that case please pull out the drill and then re-feed it. If the engine
shortly stops while drilling, switch it on again and slow down the feed speed.
After a certain period of time the abrasion of the friction plate may cause slip. They might need
to be realigned. This may only be done by a qualified technician.
Cleaning and maintenance
Warning: Always pull the mains plug
before beginning with maintenance or repairs.
Clean the machine with a dry or moist cleaning-rag and not with a stream of water. Make sure
the water does not get into the engine and the switch box. Keep the ventilation apertures
clean and do not forget to clean the core bit thread. Also grease it and check all screws.
Tighten them if necessary.
Have your tool only repaired by qualified technician and only with original spare parts. Other
parts might cause damage to a person or the machine.
Carbon brush
After you have used the machine for about 300 hours, you should check the wear of the carbon
brushes and replace them if necessary. Like any other work on the engine this must only be done by
an authorized technician.
