GENERAL POWER TOOL SAFETY WARNINGS

WARNING
Read all safety warnings and all instructions.
Failure to follow the warnings and instructions may result in
electric shock, fi re and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mainsoperated (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 fl ammable liquids, gases or dust.
   Power tools create sparks which 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 any way.
   Do not use any adapter plugs with earthed (grounded) power tools.
   Unmodifi ed 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 electric shock if your body is earthed or grounded.
   c) Do not expose power tools to rain or wet conditions.
   Water entering a power tool will increase the risk of electric 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 moving parts.
   Damaged or entangled cords increase the risk of electric shock.
   e) 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 electric shock.
   f) 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.
3. Personal safety
   a) 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 infl uence of drugs, alcohol or medication.
   A moment of inattention while operating power tools may result in serious personal injury.
   b) 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.
   c) 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 finger on the switch or energising power tools that have the switch on invites accidents.
   d) Remove any adjusting key or wrench before turning the power tool on.
   A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
   e) Do not overreach. Keep proper footing and balance at all times.
   This enables better control of the power tool in unexpected situations.
   f) 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.
   g) 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.
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 power tool 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 the power tool before making any adjustments, changing accessories, or storing power tools.
   Such preventive safety measures reduce the risk of starting the power tool accidentally.
   d) Store idle power tools out of the reach of children 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.
   e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power toolʼs operation.
   If damaged, have the power tool repaired before use.
   Many accidents are caused by poorly maintained power tools.
   f) Keep cutting tools sharp and clean.
   Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
   g) 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 diff erent from those intended could result in a hazardous situation.
5. Battery tool use and care

Regarding the temperatures and charging time of the rechargeable battery The temperatures and charging time will become as shown in Table 2.

NOTE
The recharging time may vary according to the ambient temperature and power source voltage.

Disconnect the charger’s power cord from the receptacle.
Hold the charger firmly and pull out the battery.

NOTE
Be sure to pull out the battery from the charger after use, and then keep it.

Regarding electric discharge in case of new batteries, etc.
As the internal chemical substance of new batteries and batteries that have not been used for an extended period is not activated, the electric discharge might be low when using them the first and second time. This is a temporary phenomenon, and normal time required for recharging will be restored by recharging the batteries 2 – 3 times.

How to make the batteries perform longer.

1. Recharge the batteries before they become completely exhausted.
   When you feel that the power of the tool becomes weaker, stop using the tool and recharge its battery. If you continue to use the tool and exhaust the electric current,  the battery may be damaged and its life will become shorter.
2. Avoid recharging at high temperatures.
   A rechargeable battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and the  battery life will be shortened. Leave the battery and recharge it after it has cooled for a while.

CAUTION

• If the battery is charged while it is heated because it has been left for a long time in a location subject to direct sunlight or because the battery has just been used, the  charge indicator lamp of the charger lights for 0.3 seconds, does not light for 0.3 seconds (off for 0.3 seconds). In such a case, first let the battery cool, then start charging.
• When the charge indicator lamp flickers (at 0.2-second intervals), check for and take out any foreign objects in the charger’s battery connector. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your authorized Service Center.
• Since the built-in micro computer takes about 3 seconds to confirm that the battery being charged with UC18YSL3 is taken out, wait for a minimum of 3 seconds before reinserting it to continue charging. If the battery is reinserted within 3 seconds, the battery may not be properly charged.

MOUNTING AND OPERATION

*1 When drilling fragile materials, or when conducting chipping operations or alignment operations, change the tool’s rotation speed in accordance with the task by using the  rotation speed selector switch.
NOTE

• Rotation speed cannot be adjusted until a battery is installed to the power tool and the switch has been triggered once.
• While the tool’s motor is operating, rotation speed cannot be adjusted by pressing the rotation speed selector switch.
  To adjust rotation speed, switch off the tool. Once the motor has stopped, press the rotation speed selector switch to adjust the speed.

*2 For detailed information regarding each tool, contact a HiKOKI authorized service center.

Operate this Rotary Hammer by utilizing its own weight. The performance will not be better even if it is pressed or thrust forcibly against the work surface.
Hold this Rotary Hammer with a force just sufficient to counteract the reaction.

CAUTION
After long time of use, the cylinder case becomes hot.
Therefore, be careful not to burn your hands.
Warming up (Fig. 16)
The grease lubrication system in this unit may require warming up in cold regions.
Position the end of the bit so makes contact with the concrete, turn on the switch and perform the warming up operation. Make sure that a hitting sound is produced and  then use the unit.
CAUTION
When the warming up operation is performed, hold the side handle and the main body securely with both hands to maintain a secure grip and be careful not to twist your body by the jammed drill bit.

ABOUT THE PROTECTION FUNCTIONS
This product features functions that are designed to protect the tool itself as well as the battery. While the switch is pulled, if any of the safeguard functions are triggered during operation, the display lamp will blink as described in Table 3. When any of the safeguard functions are triggered, immediately remove your finger from the switch and  follow the instructions described under corrective action.

Display lamp flashing	Cause	Solution
	Internal temperature has risen beyond the unit’s specified temperature. (Temperature increase  protection function)	Turn off the unit and allow it to cool down for about 15 minutes. When the temperature goes down, the unit is ready for use.
	Excessive pressure applied to the tool has resulted in an overload. (Overload protection function)	Remove the cause of the overburdening.
	Sensor signal read error. (Control monitoring function)	Repair may be required.

REACTIVE FORCE CONTROL
This product is equipped with a Reactive Force Control (RFC) feature that reduces jerking of the tool body.
If the tool bit is suddenly overburdened, any jerking of the tool body is reduced by activation of the slip clutch or by stopping of the motor by the sensor built into the tool  body. If the motor is stopped because of overburdening detection by the controller, the RFC indicator lamp will blink while the switch is pulled. In addition, the lamp will  continue blinking for approximately three seconds after the switch is released.
The motor will remain stopped while the lamp is blinking. (Fig. 21)
Because the RFC feature may not activate or its performance may be insufficient depending on the working environment and conditions, be careful not to suddenly  overburden the tool bit while operating.

Possible causes of sudden overburdening

1. Tool bit biting into material
2. Impact against nails, metal or other hard objects
3. Tasks involving prying or any excess application of pressure, etc.
   Also, other causes include any combination of the aforementioned.

When the reactive force control (RFC) is triggered When the RFC is triggered and the motor stops, turn off the tool’s switch and remove the cause of the overburdening  before continuing operation. 

GREASE REPLACEMENT
This Rotary Hammer is of full air-tight construction to protect against dust and to prevent lubricant leakage.
Therefore, this Rotary Hammer can be used without lubrication for long periods. Replace the grease as described below.
Grease Replacement Period
After purchase, replace grease after every 6 months of usage. Ask for grease replacement at the nearest authorized Service Center.

MAINTENANCE AND INSPECTION
