2. GENERAL SAFETY RULES
Warning: Read all instructions. Failure to follow all instructions listed below may result in electric
shock, fire and/or serious personal injury.
SAVE THE INSTRUCTIONS
The term “power tool” in all of the warnings listed bellow refers to your mains operated (corded)
power tool or baterry operated (cordless) power tool.
1.Workplace
1) Keep workplace clean and well lit.
Cluttered and dark workplaces invite accidents.
2) Do not operate power tools in explosive atmospheres, such as in the presence of flam-mable
liquids, gasses or dust. Power tools create sparks which may ingnite the dust or fumes.
3) Keep children and bysteanders away while operating a power tool. Distractions can cause you yo
lose control.
2. Electrical safety
1) 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. Unmodifed plugs and matching outlets will reduce risk
of electric shock.
2) Avoid body contact with earth or grounded surfaces such as conduits, radiators, and refrigera-
tors. There is an increased risk of electric shock if your body is earthed or grounded.
3) Do not expose power tools to rain or wet conditions. Water entering a power tools will increase
the risk of electric shock.
4) 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 cord increase
the risk of electric shock.
5) 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.
3. Personal safety
1) 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 medica-tion. A
moment of inattention while operating power tools may result in serious personal injury.
2) Use safety equipment. Always wear eye protection. Safety equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce
personal injuries.
3) Avoid suddenly starting. Ensure the switch is in the off position before plugging in. When your
finger on the switch or plugging in power tools that have the switch on invited accidents.
4) Remove any adjusting key or wrench before turning the power tool on. A wrench or a kay left
attached to a rotating part of the power tool may result in personal injury.
5) Do not overreach. Keep proper footing and balance at all times. This enables better control of the
power tool in unecpected situations.
6) 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.
7) If devices are provided for the connection of dust extraction and collction facilities, ensure these
are connected and properly used. Use of these devices can reduce dust related hazards.
4. Power tool use and care
1) 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.
2) 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.
3) Disconnect the plug from the power source before making any adjustments, changing, acces-
sories, or storing power tools. Such preventive safety measures reduce the risk of starting the
power tool accidentally.
4) 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.
5) Maintain power tools. Check for misalingnment or binding of moving parts, breakage of parts any
other condition that may affect the power tools operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly maintained power tools.
6) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
7) Use the power tool, accessories and tool bits etc., in accordance with these instructions and in
the manner intended for the particular type of power tool, taking into account the working condici-
tons and the work to be performed. Use of the power tool for operations different from those inten-
ded could result in a hazardous situation.
5. Battery tool use and care
1) Recharge only witch the charger specifed by the manufacturer. A charger that is suitable for one
type of battery pack may create a risk of fre when used with another battery pack.
2) Use power tools only witch specifically designated battery packs. Use of any other battery packs
may create a risk of injury and fire.
3) When battery pack is not in use, keep it away from other metal objects, like paper clips, coins,
keys, nails, screws or other small metal objects that can make a connection from one terminal to
another. Shorting the battery terminals together may cause burns or a fre.
4) Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact acci-
dentally occurs, fush with water. If liquid contacts eyes, additionally seek medical help. Liquid
ejected from the battery may cause irritation or burns.
6. Service
1) Have your power tool serviced by a qualifies repair person using only identical replacement parts.
This will ensure that the safety of the power tool is maintained.
3. ADDITIONAL SAFETY RULES
DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence
to hammer safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal
injury.
1. Wear ear protectors. Exposure to noise can cause hearing loss.
2. Use auxiliary handles supplied with the tool. Loss of control can cause personal injury.
3. Hold tools by insulated gripping surfaces when performing an operation where the cutting tool
may contact hidden wiring or its own cord. Contact while a “live” wire will make exposed metal
parts of the tool “live” and shock the operator.
4. Wear a hard hat (safety helmet), safety glasses and/or face shield. Ordinary eye or sun glasses
are NOT safety glasses. It is also highly recommended that you wear a dust mask and thickly
padded gloves.
5. Be sure the bit is secured in place before operation.
6. Under normal operation, the tool is designed to product vibration. The screws can come loose
easily, causing a breakdown or accident. Check tightness of screws carefully before operation.
7. In cold weather or when the tool has not been used for a long time, let the tool warm up for a while
be operating it under no load. This will loosen up the lubrication. Without proper warm up, hamme-
ring operation is difficult.
8. Always be sure you have a firm footing. Be sure no one is below when using the tool in high
locations.
9. Hold the tool firmly with both hands.
10. Keep hands away from moving parts.
11. Do not leave the tool running. Operate the tool only when hand-held.

Replacement of carbon brushes
Whenever carbon brushes must be replaced, they cut out the tool automatically. When this occurs,
loosen the bolts which secure the rear cover. Remove the rear cover. Then replace both carbon
brushes at the same time. Use only identical carbon brushes.
Lubrication
This tool requires no hourly or daily lubrication because it has a grease-packed lubrication system.
Lubricate the tool every time the carbon brushes are replaced.
Run the tool for several minutes to warm it up. Switch off and unplug the tool. Remove the crank cap
using oringial lock nut wrench (optional accessory). Rest the tool on the table with the bit end
pointing upwards. This will allow the old grease to collect inside the crank housing. Wipe out the old
grease inside and replace with a fresh grease (30 g). Use only original genuine grease (optional
accessory). Filling with more than the specified amount of grease (approx. 30 g) can cause faulty
hammering action or tool failure. Fill only with the specified amount of grease. Reinstall the crank
the cap excessiveely. It is made of resin and is subject to breakage.
