2. SAFETY
2.1. GENERAL POWER TOOL SAFETY WARNINGS
Warning
Read all safety warnings, instructions, illustrations and specifications provided with this
power tool. Failure to follow all instructions listed below may result in electric shock, fire and/
or serious injury.
Note
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 (cord-
less) power tool.
2.1.1. WORK AREA SAFETY
1. Keep the work area clean and well lit. Cluttered or dark areas invite accidents.
2. Do not operate power tools in an explosive atmosphere, for example in the presence of flammable
liquids, gases or dust. Power tools create sparks, which can ignite dust or fumes.
3. Keep children and bystanders away while operating the power tool. Distractions can cause you to lose
control of the tool.
2.1.2. ELECTRICAL SAFETY
1. The power tool connector must be adapted to the socket. Never modify the connector in any way what-
soever. Do not use adapter plugs with earthed (grounded) power tools. Unmodified plugs and suitable
sockets reduce the risk of electric shock.
2. Avoid contact with earthed surfaces such as pipes, radiators, cookers, and refrigerators. There is an
increased risk of electric shock if your body is in direct contact with the ground.
3. Do not expose power tools to rain or damp conditions. The entry of water into a power tool increases the
risk of electric shock.
4. Do not mishandle the power cord. Never use the cord for carrying, pulling or unplugging the power
tool. Keep cord away from heat, oil, sharp edges and moving parts. Damaged or entangled cords increase
the risk of electric shock.
5. Use an extension cord suitable for outdoor use when operating power tools outdoors. Use a cord suitable
for outdoors to reduce the risk of electric shock.
6. Use a power supply protected by a residual current device (RCD) when the power tool is operated in a
damp location. Use of an RCD reduces the risk of electric shock.
Note
The term “Residual Current Device” (RCD) can be replaced by “Ground Fault Circuit Interrupter” (GFCI) or
“Earth Leakage Circuit Breaker” (ELCB).
2.1.3. PERSONAL SAFETY
1. Stay alert, watch what you are doing, and use common sense when operating the 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 when using a power tool can result in serious personal injury.
6

PRUNING SHEARS AND 250 BATTERY PRUNION & VINION
32_118367-K
2. Use personal protective equipment. Always wear eye protection. Safety equipment such as dust masks,
non-slip safety shoes, helmets, or ear protection used at the appropriate times reduces injuries.
3. Avoid accidental starting of the tool. Make sure the switch is in the off position before you connect the
tool to the power source and/or battery pack, pick it up, or carry it. Carrying a power tool with your finger
on the switch or connecting a power tool with the switch in the ‘on’ position can cause accidents.
4. Remove any adjusting wrench before switching the electric tool on. A wrench left attached to a rotating
part can cause injury.
5. Do not rush. Keep proper footing and balance at all times. This provides better control of the power tool
in unexpected situations.
6. Dress appropriately. Do not wear loose clothing or jewellery. Keep hair and clothing away from moving
parts. Loose clothes, jewellery or long hair can get caught in moving parts.
7. If devices are provided for connecting dust extraction and collection equipment, ensure that these are
connected and properly used. Use of dust collection can reduce dust-related hazards.
8. 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.
2.1.4. POWER TOOL USE AND CARE
1. Do not force the power tool. Use the power tool suited for the job. The adapted power tool does the work
better and more safely at the speed it was built to operate at.
2. Do not use the power tool if the switch does not allow it to be switched on and off. Power tools that
cannot be controlled by a switch are dangerous and must be repaired.
3. Unplug the tool from the socket or remove the battery (if possible) before any adjustment, change of
accessory or storage. These preventive safety measures reduce the risk of accidentally starting the power
tool.
4. When not in use, keep power tools out of the reach of children and do not allow persons unfamiliar
with the power tool or these instructions to operate it. Power tools are dangerous when operated by inex-
perienced users.
5. Maintenance of the power tool and its accessories is mandatory. Check that the moving parts are not
out of alignment or jammed, that there are no broken parts or that there is no other condition which
could affect the operation of the power tool. If damaged, repair the power tool before using it. Many
accidents are due to poorly maintained power tools.
6. Keep the cutting elements sharp and clean. Properly maintained cutting tools with sharp cutting elements
are less likely to jam and are easier to control.
7. Use the power tool, accessories, blades, etc. in accordance with these instructions, taking into account
the working conditions and the work to be done. Use of the power tool for operations different from those
intended could result in a hazardous situation.
8. Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasp-
ing surfaces do not allow for safe handling and control of the tool in unexpected situations.
2.1.5. BATTERY TOOL USE AND CARE
1. Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of
battery pack may create a risk of fire when used with another battery pack.
2. Use power tools only with 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 fire.
4. Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally
occurs, wash away with water. If liquid contacts eyes, seek additional medical help. Liquid ejected from
the battery may cause irritation or burns.
5. Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit
unpredictable behaviour resulting in fire, explosion or risk of injury.
6. Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature
above 130 °C may cause explosion.
7

PRUNING SHEARS AND 250 BATTERY PRUNION & VINION

5.1. USAGE TIPS
• You must take all necessary care to prevent catching the lead of the pruning shears in the branches. To do this,
attach the lead to your arm using the wrist strap provided. (see page Section 4.3, “Putting the lead and wrist
strap in place”)
18

PRUNING SHEARS AND 250 BATTERY PRUNION & VINION
32_118367-K
• The operating time and service life of the pruning shears mainly depend keeping the blade properly sharpened
and adjusted.
• It is essential to remove the burrs (wire edge) from the cutting edge of the blade, and to file it off within the first
15 minutes of use.
• We recommend that you do not disconnect the lead of the pruning shears from the battery unit after use each
day, but wind it around the "battery" unit and replace them both in their carry-case.
There are various usage modes available to best meet your working practices and to save battery power. The
battery is supplied in the most efficient mode.
• These modes are shown on the display.
• The factory setting for the pruning shears is "ramp-up" mode (U4).
5.2. USAGE MODES

Note
Remove your finger from the trigger to open the blades wide, no matter which function is chosen.
5.3. OPTICAL TRIGGER
The blade stays half-open as long as the optical system (1) detects your finger on the trigger. When your finger
releases the trigger, the optical system tells the blade to open fully.
This option helps when cutting small wood, thus saving energy. After a few minutes' use, this optical system becomes
an essential feature of your daily work.
