Safety instructions
General power tool safety warnings
Warning! Read all safety warnings and all instructions. Failure to follow all
instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in all of the warnings listed below 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 and dark areas invite
accidents.
b. Do not operate power tools in explosive atmospheres, such as in the
presence of flammable 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.
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 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.
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 influence 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. Avoid accidental 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
tools 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 different from those intended could result in a hazardous situation.
5. Battery tool use and care
a. 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.
b. Use power tools only with specifically designated battery packs. Use
of any other battery packs may create a risk of injury and fire.
c. 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 bums or a fire.
d. Under abusive conditions, liquid may be ejected from the battery;
avoid contact. If contact accidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help. Liquid ejected from the battery
may cause irritation or burns.
6. Service
a. Have your power tool serviced by a qualified repair person using only identical replacement parts. This will make sure that the safety of the power tool is maintained.

The vibration emission value during actual use of the power tool can differ
from the declared value depending on the ways in which the tool is used. The
vibration level may increase above the level stated.
When assessing vibration exposure to determine safety measures required by 2002/44/EC to protect persons regularly using power tools in employment, an estimation of vibration exposure should consider, the actual conditions of use and the way the tool is used, including taking account of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle in addition to the trigger time.
Pruning
Before attempting to prune a tree, ensure there are not bylaws or regulations that would prohibit or control the felling of the tree.
♦ Be aware of the direction a branch may fall. Consider all conditions that
may affect the direction of fall, including:
– the length and weight of the branch to be cut
– the intended direction of fall
– any unusual heavy limb structure or decay
– the presence of surrounding trees and obstacles,
– including overhead lines
– the intertwinement with other branches
– the speed and direction of the wind.
♦ Consider access to the tree limb.
Tree branches are liable to swing towards the tree trunk. In addition to the
user, any bystander, building or object below the branch is at risk of being
struck by the branch.
