WARNING – To reduce the risk of injury, user must read instruction manual!

General safety rules

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.
Save all warnings and instructions for future refer-ence.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

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.
Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety

Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
Do not expose power tools to rain or wet condi- tions. Water entering a power tool will increase the risk of electric shock.
Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of elec- tric shock.
If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
NOTE! The term “residual current device (RCD)” may be replaced by the term “ground fault circuit interrupter (GFCI)” or “earth leakage circuit breaker (ELCB)”.
Warning! Never touch the exposed metal surfaces on gearbox, shield, and so on because touching metal surfaces will be interfered with the electromagnetic wave, thus causing potential injury or accidents.

Personal safety

Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and / or battery pack, picking up or carrying the tool. Carrying power tools with your fin- ger on the switch or energising power tools that have the switch on invites accidents.
Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left at- tached to a rotating part of the power tool may result in personal injury.
Do not overreach. Keep proper footing and bal- ance at all times. This enables better control of the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.
Warning! Power tools can produces an electromag- netic field during operation. This field may under some circumstances interfere with active or passive medical implants. To reduce the risk of serious or fatal injury, we recommend persons with medical implants to con- sult their physician and the medical implant manufac- turer before operating this power tool.

Power tool use and care

The persons with lowered psychophysical or men- tal aptitudes as well as children can not operate the power tool, if they are not supervised or instructed about use of the power tool by a person responsible for their safety.
Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
Disconnect the plug from the power source and / or the battery pack from the power tool be- fore making any adjustments, changing accesso- ries, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
Store idle power tools out of the reach of chil- dren and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s op- eration. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazard- ous situation.
Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.
Note that when you operate a power tool, please hold the auxiliary handle correctly, which is helpful when controlling the power tool. Therefore, proper holding can reduce the risk of accidents or injuries.

Service

Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
Follow instruction for lubricating and changing accessories.

Special safety warnings

Wear ear protectors when impact drilling. Exposure to noise can cause hearing loss.
Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
Notice the power voltage: in power connection, you must confirm that if the power voltage is the same to the voltage marked in the tool’s data plate. If the power voltage is higher than the appropriate voltage, the acci- dents will be resulted to the operators, and at the same time, the tool will be destroyed. Therefore, if the power voltage has not been confirmed, then you shall never plug in arbitrarily. On the contrary, when the power voltage is lower than the required voltage, the motor will be damaged.

Safety guidelines during power tool operation

All instructions have to be read. In case of using the machine not in accordance with the following provisions, electric shock, fire or serious injury may occur.

Check that the drill bit has been clamped in proper position or not prior to operation.
Power tool working will generate vibration and you should carefully confirm that screws in different places still are tightened or not prior to operation.
Wear blinder in operation to protect eyes.
Maintain the keenness of the drill bit so as to achieve the optimum and safest efficiency.
When replace or assemble the accessories, the op- eration must follow the instructions of the accessory strictly.
If the productor has any problems, you must not try to repair personally, please take it to the local assigned maintenance center for inspection.
Fix the workpiece as far as possible. The workpiece shall be fixed with fixing device or pincer pliers, which shall be fastness than holding the piece in hand.
Before powered on, the switch must be confirmed in “off” position; before you put down the power tool, it must be turned off and the power plug must be pulled out.
When the accessory is totally static, then the power tool can be put down.
Never let the power wire touch the drill bit or sur- rounding parts in operation, or the power wire may be damaged. The power tool with broken wires must not be used. If the power wire is damaged in the working, then the damaged wire must not be touched, and the plug must be pulled out immediately. The damaged wire shall increase the danger of user’s electric shock.
Chiseling walls, floors or on similar occasions, pay attention to keep away from gas, tap water pipeline and electric wire and operating tools in those places shall keep away from touching metal parts. The appropriate detector shall be used so as to find out the loca- tion of the concealed power wire. Or you can require the relevant data from the local power supply entity. The wires that are drilled through shall result in the fire and electric shock. The damaged gas pipe will resulted in the explosion. If the water pipe is drilled through, the property loss will be caused.
If the accessory installed on the power tool gets clamped, the power tool must be turned off immedi- ately and stay calm. At the time, the power tool will generate ultrahigh reaction torque, and result in the return stroke. The accessory installed on the power tool is easy to be clamped, like: the power tool is in hypercharge, or the accessory installed on the power tool inclines in the workpiece.
The concealed electric wire or the power wire of the power tool may be cut off in operation, and then the in- sulated handle must be held to operate the power tool. If the power tool contacts the charged circuit, then the metal parts on the power tool shall conduct electricity, and the operator may have electric shock.
Two handles of the productor must be held with both hands tightly in operation, and the base must be stable. Both hands can hold the power tool stably; one hand operation must be avoided.
The flat chisel must not be used in the rotational state (such as rotary drill and hammer drill), or the chisel will be blocked and the power tool will lose control.
Only when you wear gloves then you can touch the accessories, the drill bits and accessories will be hot in operation, and it is easy to get burn. Never immediately touch the drill bit or parts around it upon the end of work, for those parts will be scalding and scald your skin. Wear gloves and middle rest can reduce the vibration and the injury to the hands and arms.
Hands and body must not be placed between the power tool and the wall or column so as to prevent the power tool from flying off when the drill bits gets blocked.
In case using extended power wire, please use double insulation power wire with the same specification as the power tool.
Avoid stopping an electric tool motor when loaded.
Never remove any chips or fragments with your electric tool’s motor running.
Never change the borer and chisel design or use attachments and appliances, which are not recom- mended for your electric tool.
When working, never press the electric tool too hard, as this might lead to the borer or chisel seizing and motor overloading.
Avoid the drill, borer and chisel seizing in the material worked in. If this happens, do not try to release them with your perforator’s motor. It may damage the motor.
Never force out the drills, borers or chisels stuck in the material you are working on with a hammer or other objects the chipped off metal particles may harm both the operator and the persons who are nearby.
Avoid overheating your electric tool, when using it for a long time.

Warning: the chemical substances contained in dust generated in sanding, cutting, sawing, grinding, drilling and other construction industry activities may result in cancer, congenital deficiency or be harmful to the fertility. The ion of some chemical substances shall be:

Before any repair and replacement work to the machine, the power plug must be pulled out firstly.
The transparent two silicon oxide and other ma- sonry products in the wall bricks and cement; the chromium arsenic (CCA) in wood with chemical treatment. The harm degree of these substances shall depend on the frequent degree of you carrying out these works. If you want to reduce the contact with these chemical substances, please work in the place with ventilation and you shall use the appli- ances with safety certificates (such as the dust mask designed with tiny dust filter).

Press and hold retainer 4.
Move depth stop 5 to set a required drilling depth.
Release retainer 4.

Mounting / replacement of accessories (see fig. 3)

Borers SDS PLUS are able, due to the designed features of the chuck SDS PLUS, to travel freely to some extent. This causes radial run-out at idle running that will be automatically centred during the drilling. It doesn’t make any impact on the precision of bore drilling.

Before installing the borer (chisel), clean it and lubricate the shank with a thin layer of oil.
When mounting borer (chisel):
– insert (slightly twisting) the borer (chisel) into the chuck 1 (SDS PLUS) against stop (see fig. 3.1);
– test the borer (chisel) fixing by trying to remove it from chuck 1 (SDS PLUS).
When removing borer (chisel):
– move fixing bush 3 back and hold it in this position (see fig. 3.2);
– extract the borer (chisel) from the chuck 1 (SDS PLUS);
– release fixing bush 3.

Gloves are to be used when removing the borer (chisel) from chuck 1 (SDS PLUS), as the borer (chisel) may be dangerously hot after long drilling.

Replacing the dust protection casing (see fig. 4)
Dust protection casing 2 prevents the dust from entering the SDS PLUS chuck. Never use your power tool with a damaged dust protection casing 2 – if damaged, it must be immediately replaced. You can either do it on your own, or contact the CROWN service center.

Move fixing bush 3 back and hold it in that position (see fig. 4).
Pull dust protection casing 2, and remove it.
Install a new dust protection casing 2.
Release fixing bush 3.

Adapter for chuck SDS PLUS

SDS PLUS adapter 14 and screw 13 enable using gear rim chuck 15.
Never use SDS PLUS adapter 14 in the impact drilling or chiselling operation modes.
Drills that don’t belong to the SDS PLUS system are not allowed for the percussion drilling.

Mounting / dismounting of the gear rim chuck (see fig. 5-6)

Screw the gear rim chuck 15 onto the SDS PLUS adapter 14 and lock it in with the screw 13 (see fig. 5).
Install the SDS PLUS adapter 14 into the chuck 1 (SDS PLUS), repeating the same steps as when mounting the borer (chisel) see fig. 6.
When dismantling, repeat the steps described above in the reverse order.

Attention: keep in mind that in the process of mounting / dismounting of the gear rim chuck 15 the screw 13 has a lefthand thread.

Mounting / replacement of accessories

With long-term use the drill bit may become very warm; use gloves to remove it.

Gear rim chuck (see fig. 7)

Release the cams grip with drill chuck key 16, then rotate the quill of gear rim chuck 15 counter-clockwise with your hand (see fig. 7) until the cams move apart at the distance allowing an accessory to be mounted / replaced.
Mount / replace an accessory.
Rotate the quill of gear rim chuck 15 clockwise with your hand in order to lock the accessory mounted. Do not allow the accessory to become distorted.
Tighten the cams of gear rim chuck 15 with drill chuck key 16 applying a similar torque to each of the three openings on the side surface of the chuck.

Initial operation of the power tools

Always use the correct supply voltage the power supply voltage must match the information quoted on the power tool identification plate.
The power tool is supplied properly lubricated and ready for use.
A new power tool needs some time for its parts to run in before a full load operation. The run-in period duration is about 5 hours of operation.
The gear lubrications require a short time to get warm. Depending on the ambient temperature this period of time can alter within the range of approximately 15 s (at ambient temperature of 32°С) up to 2 minutes (at ambient temperature of 0°С).

Switching the power tool on / off
Short-term switching on / off
To switch on, press and hold on / off switch 11, to switch off – release it.
Long-term switching on / off
Switching on:
Push on / off switch 11 and lock it in the position with lock-on button 12.
Switching off:
Push and release on / off switch 11.

Design features of the power tool
Function switch (see fig. 8)
Switching the operation modes shall be carried out only in the off mode of the tool’s motor.
Function switch 8 is fitted with lock button 7 that is used to fix the function switch 8 in a set position. Rotate function switch 8 while pressing button 7 in order to set a desired operating mode.

Function switch 8 is designed for the switching the following operation modes of the tool:

Drilling (set the function switch 8 in the position indicated in figure 8.1) – non-percussion drilling in wood, synthetics, metal.
Percussion drilling (set the function switch 8 in the position indicated in figure 8.2) – percussion drilling in masonry, concrete, natural stone.
Chisel rotation (set switch 8 in the position shown on figure 8.3) – this mode does not allow operating your power tool, but allows setting the chisel in a comfortable position for chiseling works.
Chiselling (set the function switch 8 in the position indicated in figure 8.4) – chiselling ducts in masonry, concrete, stone, removing ceramic tiles.
In order to make switching between the operation modes smoother, rotate slight- ly chuck 1 (SDS PLUS) by hand.

Stepless speed adjustment

Speed is controlled from 0 to maximum by pressing force of on / off switch 11. Weak pressing results in low revolutions, which enable a smooth power tool switch-on.

Changing the rotational directions (see fig. 9)
Change the direction of rotation only after a full stop of the motor, acting otherwise may cause damage to the power tool.
Clockwise rotation (drilling, fastening of screws) – move the rotational direction switch 10 as it is shown in fig. 9.1.
Counter clockwise rotation (unscrewing the screws) – move the rotational direction switch 10 as it is shown in fig. 9.2.
Safety clutch
The safety clutch protects the power tool against overload and damage in case of accessory sticking during drilling.

Recommendations on the power tool operation

Wear thick soft gloves when working to reduce vibration impact on your body.

Always use additional handle 6 when working, it will ensure a better control of your electric tool and reduce recoil.
At impact drilling the result does not depend on the pressing force you apply to your electric tool, which is due to the impact mechanism design. This is why do not exert excessive pressure on your power tool, as it may result in borer seizing and motor overload.
In order to decrease dust production when drilling holes in walls and ceilings, take actions indicated in fig. 10-11.

Caution: drill wood and metals in the impactless drilling operation mode only.

Grease the drill bit regularly when drilling holes in met- als (except drilling non-ferrous metals and their alloys).
When drilling hard metals, apply more force to the power tool and lower the rotation speed.
When drilling large diameter holes in metal, first drill a hole with a smaller diameter and ream it till the nec- essary diameter (see fig. 12).
In order to avoid splitting of the surface at an exit point of a drill bit when drilling holes in wood, follow the instructions shown in figure 13.
When drilling holes in glazed ceramic tiles, in order to improve the drill centering accuracy and to save the glaze from damage, apply adhesive tape to the presumed hole center and drill after that (see fig. 14).
Caution: drill tiles in the impactless drilling opera- tion mode only.

Power tool maintenance / preventive measures
Before carrying out any works on the power tool it must be disconnected from the mains.
Cleaning of the power tool
An indispensable condition for a safe long-term exploitation of the power tool is to keep it clean. Regularly flush the power tool with compressed air thought the ventilation slots 9.
