GENERAL SAFETY INSTRUCTIONS

4

Warning! Read all instructions. Failure to follow all instructions listed belowmay result in electric shock, fire and/or serious injury. The term "power tool" inall of the warnings listed below refers to your mains-operated (corded) powertool or battery-operated (cordless) power tool.

Save these instructions

1) Work area

a) Keep work area clean and well lit. Cluttered and dark areas invite accidents.

b) Do not operate power tools in explosive atmospheres, such as in thepresence of flammable liquids, gases or dust. Power tools create sparkswhich may ignite the dust or fumes.

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

2) Electrical safety

a) Power tool plugs must match the outlet. Never modify the plug in anyway. Do not use any adapter plugs with earthed (grounded) power tools.Unmodified plugs and matching outlets will reduce risk of electric shock.

b) Avoid body contact with earthed or grounded surfaces such as pipes,radiators, ranges and refrigerators. There is an increased risk of electricshock if your body is earthed or grounded.

c) Do not expose power tools to rain or wet conditions. Water entering apower tool will increase the risk of electric shock.

d) Do not abuse the cord. Never use the cord for carrying, pulling orunplugging the power tool. Keep cord away from heat, oil, sharp edges ormoving parts. Damaged or entangled cords increase the risk of electric shock.

e) When operating a power tool outdoors, use an extension cord suitable foroutdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

3) Personal safety

a) Stay alert, watch what you are doing and use common sense whenoperating a power tool. Do not use a power tool while you are tired orunder the influence of drugs, alcohol or medication. A moment ofinattention while operating power tools may result in serious personal injury.

b) Use safety equipment. Always wear eye protection. Safety equipment suchas dust mask, non-skid safety shoes, hard hat, or hearing protection used forappropriate conditions will reduce personal injuries.

c) Avoid accidental starting. Ensure the switch is in the off-position beforeplugging in. Carrying power tools with your finger on the switch or plugging inpower tools that have the switch on invites accidents.

d) Remove any adjusting key or wrench before turning the power tool on. Awrench or a key left attached to a rotating part of the power tool may result inpersonal injury.

e) Do not overreach. Keep proper footing and balance at all times. Thisenables better control of the power tool in unexpected situations.

GENERAL SAFETY INSTRUCTIONS (cont.)

f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair,clothing and gloves away from moving parts. Loose clothes, jewellery or longhair can be caught in moving parts.

g) If devices are provided for the connection of dust extraction and collectionfacilities, ensure these are connected and properly used. Use of these devicescan reduce dust-related hazards.

4) Power tool use and care a) 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.

b) Do not use the power tool if the switch does not turn it on and off. Any powertool that cannot be controlled with the switch is dangerous and must be repaired.

c) Disconnect the plug from the power source and/or the battery pack from thepower tool before making any adjustments, changing accessories, or storingpower tools. Such preventive safety measures reduce the risk of starting thepower tool accidentally.

d) Store idle power tools out of the reach of children and do not allow personsunfamiliar with the power tool or these instructions to operate the powertool. Power tools are dangerous in the hands of untrained users.

e) Maintain power tools. Check for misalignment or binding of moving parts,breakage of parts and any other condition that may affect the power toolsoperation. If damaged, have the power tool repaired before use. Manyaccidents are caused by poorly maintained power tools.

f) If operating a power tool in a damp location is unavoidable, use a residualcurrent device (RCD) protected supply. Use of an RCD reduces the risk ofelectric shock.

g) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharpcutting edges are less likely to bind and are easier to control.

h) Use the power tool, accessories and tool bits etc. in accordance with theseinstructions and in the manner intended for the particular type of power tool,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 ahazardous situation.

5) Service a) 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. b) If the supply cord is damaged, it must be replaced by the manufacturer, its

service agent or similarly qualified persons in order to avoid a hazard.

OPERATION

BEFORE ATTACHING OR REMOVING ANY ACCESSORIES FROM THE DRILL,BE SURE TO DISCONNECT THE DRILL FROM THE POWER SUPPLY.

Depth Rod

The metal depth rod (11) allows you to drill to a predetermineddepth. Loosen the 360° side handle (9) by turning anti-clockwise.Feed the metal depth rod (11) so the drill bit extends beyondthe end of the metal depth rod (11) to the required drilling depth.To secure the metal depth rod (11) in position, tighten the 360°side handle (9) by turning clockwise (Fig.1). Once the metal depthrod (11) has been set, proceed to drill the hole until the end of the metal depth rod (11)touches the work piece, then remove the drill bit from the hole. The depth of the holeshould be the same as the metal depth rod (11) was set to.

Important! Always lubricate the SDS+ accessory fitment prior to inserting them intothe drill. Using your finger, apply grease sparingly to the shaft of the accessory fromthe tub of grease (18) supplied.Lubricating the SDS+ accessories will prolong the life of your rotary hammer drill.Non-lubrication of accessories will void your warranty.

SDS+ Accessories

Important: The 13mm keyed chuck (15) is not intended foruse with SDS+ accessories. SDS+ accessories should be fitteddirectly into the drill's SDS+ accessory holder (1). Using SDS+accessories in the 13mm keyed chuck (15) may result inpermanent damage to the chuck. Such damage will not becovered under warranty.

Fitting a SDS+ Accessory

Prior to fitting a SDS+ accessory, remove any dust or debrisfrom the SDS+ shank of the accessory (Fig.2).

Pull the accessory locking sleeve (10) back towards the body of thedrill away from the SDS+ accessory holder (1). Rotate and insertthe accessory to make sure it has been inserted as far as it will go,then release the accessory locking sleeve (10) (Fig.3).

With the accessory locking sleeve (10) released, check the accessory has been lockedinto place by trying to pull it out. The SDS+ accessories will have a small amount (approx.10-12mm) of back and forth movement from the SDS+ accessory holder (1), this is normal.

To remove the SDS+ accessory, pull the accessory locking sleeve (10) back towards thebody of the drill away from the SDS+ accessory holder (1) and remove the SDS+ accessory.

Clean the accessory shank with a cloth after removal.

Note: You may notice some “wobble” of the accessory when the drill is run in a noload condition. This is due to the assembly of the quick change SDS+ accessoryholder. This is normal, the bit automatically centres itself and produces accurate holesas soon as load is placed upon it.

Warning: Accessories may be hot after use. Avoid direct contact with skin, usegloves or a cloth to remove.
