GENERAL POWER TOOL SAFETY WARNINGS
WARNINGRead all safety warnings and all instructions.Failure to follow the warnings and instructions may result inelectric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless)power tool.1) Work area safety
a) Keep work area clean and well lit.Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres,such as in the presence of flammable liquids, gasesor dust.Power tools create sparks which may ignite the dustor fumes.
c) Keep children and bystanders away while operatinga power tool.Distractions can cause you to lose control.
2) Electrical safetya) 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 reducerisk 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 electric shock if yourbody is earthed or grounded.
c) Do not expose power tools to rain or wet conditions.Water entering a power tool will increase the risk ofelectric shock.
d) 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 movingparts.Damaged or entangled cords increase the risk ofelectric shock.
e) When operating a power tool outdoors, use anextension cord suitable for outdoor use.Use of a cord suitable for outdoor use reduces therisk of electric shock.
f) If operating a power tool in a damp location isunavoidable, use a residual current device (RCD)protected supply.Use of an RCD reduces the risk of electric shock.
3) Personal safetya) 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 underthe influence of drugs, alcohol or medication.A moment of inattention while operating power toolsmay result in serious personal injury.
b) Use personal protective equipment. Always wear eyeprotection.Protective equipment such as dust mask, non-skidsafety shoes, hard hat, or hearing protection used forappropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch isin the off-position before connecting to power sourceand/or battery pack, picking up or carrying the tool.Carrying power tools with your finger on the switchor energising power tools that have the switch oninvites accidents.
d) Remove any adjusting key or wrench before turningthe power tool on.A wrench or a key left attached to a rotating part ofthe power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balanceat all times.This enables better control of the power tool inunexpected situations.
f) Dress properly. Do not wear loose clothing orjewellery. Keep your hair, clothing and gloves awayfrom moving parts.Loose clothes, jewellery or long hair can be caughtin moving parts.
g) If devices are provided for the connection of dustextraction and collection facilities, ensure these areconnected and properly used.Use of dust collection can reduce dust related hazards.
4) Power tool use and carea) Do not force the power tool. Use the correct power
tool for your application.The correct power tool will do the job better and saferat the rate for which it was designed.
b) Do not use the power tool if the switch does notturn it on and off.Any power tool that cannot be controlled with theswitch is dangerous and must be repaired.
c) Disconnect the plug from the power source and/orthe battery pack from the power tool before makingany adjustments, changing accessories, or storingpower tools.Such preventive safety measures reduce the risk ofstarting the power tool accidentally.

(When using dustcollector (B) attached to a drill bit that has more than190 mm of overall length, dust collector (B) cannottouch the concrete surface and will rotate. Thereforeplease use dust collector (B) by attaching to drill bitswhich have 166 mm, 160 mm, and 110 mm overalllength.)
� Dump particles after every two or three holes whendrilling.
� Please replace the drill bit after removing dustcollector (B).
6. Selecting the driver bitScrew heads or bits will be damaged unless a bitappropriate for the screw diameter is employed todrive in the screws.
7. Confirm the direction of bit rotation (Fig. 5)The bit rotates clockwise (viewed from the rear side)by pushing the R-side of the push button.The L-side of the push button is pushed to turn the bitcounterclockwise.
HOW TO USE
CAUTIONTo prevent accidents, make sure to turn the switchoff and disconnect the plug from the receptacle whenthe drill bits and other various parts are installed orremoved. The power switch should also be turnedoff during a work break and after work.
1. Switch operationThe rotation speed of the drill bit can be controlledsteplessly by varying the amount that the triggerswitch is pulled. Speed is low when the trigger switchis pulled slightly and increases as the switch is pulledmore. Continuous operation may be attained bypulling the trigger switch and depressing the stopper.To turn the switch OFF, pull the trigger switch againto disengage the stopper, and release the triggerswitch to its original position.However, the switch trigger can only be pulled inhalfway during reverse and rotates at half the speedof forward operation.The switch stopper is unusable during reverse.
2. Rotation + hammeringThis rotary hammer can be set to rotation andhammering mode by pressing the push button andturning the change lever to the mark (Fig. 6).
(1) Mount the drill bit.(2) Pull the trigger switch after applying the drill bit tip to
the drilling position (Fig. 7).(3) Pushing the rotary hammer forcibly is not necessary
at all. Pushing slightly so that drill dust comes outgradually is sufficient.
CAUTIONWhen the drill bit touches construction iron bar, thebit will stop immediately and the rotary hammer willreact to revolve. Therefore grip the side handle andhandle tightly as shown in Fig. 7.
3. Rotation onlyThis rotary hammer can be set to rotation only modeby pressing the push button and turning the changelever to the mark (Fig. 8).
To drill wood or metal material using the drill chuckand chuck adapter (optional accessories), proceed asfollows.Installing drill chuck and chuck adapter (Fig. 9).
(1) Attach the drill chuck to the chuck adapter.(2) The part of the SDS-plus shank is the same as the
drill bit. Therefore, refer to the item of “Mounting thedrill bit” for attaching it.

CAUTION� Application of force more than necessary will not
only expedite the work, but will deteriorate the tipedge of the drill bit and reduce the service life of therotary hammer in addition.
� Drill bits may snap off while withdrawing the rotaryhammer from the drilled hole. For withdrawing, it isimportant to use a pushing motion.
� Do not attempt to drill anchor holes or holes inconcrete with the machine set in the rotation onlyfunction.
� Do not attempt to use the rotary hammer in therotation and striking function with the drill chuck andchuck adapter attached. This would seriously shortenthe service life of every component of the machine.
4. When driving machine screws (Fig. 10)First, insert the bit into the socket in the end of chuckadapter (D).Next, mount chuck adapter (D) on the main unitusing procedures described in 4 (1), (2), (3), put thetip of the bit in the slots in the head of the screw,grasp the main unit and tighten the screw.
CAUTION� Exercise care not to excessively prolong driving time,
otherwise, the screws may be damaged by excessiveforce.
� Apply the rotary hammer perpendicularly to the screwhead when driving the screw; otherwise, the screwhead or bit will be damaged, or driving force will notbe fully transferred to the screw.
� Do not attempt to use the rotary hammer in therotation and striking function with the chuck adapterand bit attached.
5. When driving wood screws (Fig. 10)(1) Selecting a suitable driver bit
Employ plus-head screws, if possible, since the driverbit easily slips off the heads of minus-head screws.
(2) Driving in wood screws� Prior to driving in wood screws, make pilot holes
suitable for them in the wooden board. Apply the bitto the screw head grooves and gently drive the screwsinto the holes.
� After rotating the rotary hammer at low speed for awhile until the wood screw is partly driven into thewood, squeeze the trigger more strongly to obtainthe optimum driving force.
CAUTIONExercise care in preparing a pilot hole suitable for thewood screw taking the hardness of the wood intoconsideration. Should the hole be excessively smallor shallow, requiring much power to drive the screwinto it, the thread of the wood screw may sometimesbe damaged.
6. Hammering onlyThis rotary hammer can be set to hammering onlymode by pressing the push button and turning thechange lever to the mark (Fig. 11).
(1) Mount the bull point or cold chisel.(2) Press the push button and set the change lever to
middle of mark and mark (Fig. 12).The rotation is released, turn the grip and adjust thecold chisel to desired position (Fig. 13).
