General Machine Safety Warnings
WARNING Read all safety warnings, instructions,
illustrations and specifications provided with this machine.
Failure to follow all instructions listed below may result in
electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term "machine" in the warnings refers to your mains-operated
(corded) machine or battery-operated (cordless) machine.
Work area safety
Keep work area clean and well lit. Cluttered or dark areas
invite accidents.
Do not operate machines in explosive atmospheres, such as in
the presence of flammable liquids, gases or dust. Machines
create sparks which may ignite the dust or fumes.
Keep children and bystanders away while operating a machine.
Distractions can cause you to lose control.
Electrical safety
Machine plugs must match the outlet. Never modify the plug
in any way. Do not use any adapter plugs with earthed (grounded)
machines. Unmodified plugs and matching outlets will reduce
risk of electric shock.
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.
Do not expose machines to rain or wet conditions. Water
entering a machine will increase the risk of electric shock.

2
Do not abuse the cord. Never use the cord for carrying, pulling
or unplugging the machine. Keep cord away from heat, oil,
sharp edges or moving parts. Damaged or entangled cords
increase the risk of electric shock.
When operating a machine outdoors, use an extension cord
suitable for outdoor use. Use of a cord suitable for outdoor
use reduces the risk of electric shock.
If operating a machine in a damp location is unavoidable, use
a residual current device (RCD) protected supply. Use of an
RCD reduces the risk of electric shock.
Personal safety
Stay alert, watch what you are doing and use common sense when
operating a machine. Do not use a machine while you are tired
or under the influence of drugs, alcohol or medication. A
moment of inattention while operating machines may result in
serious personal injury.
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.
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 machine. Carrying machines
with your finger on the switch or energising machines that
have the switch on invites accidents.
Remove any adjusting key or wrench before turning the machine
on. A wrench or a key left attached to a rotating part of the
machine may result in personal injury.

3
Do not overreach. Keep proper footing and balance at all times.
This enables better control of the machine in unexpected
situations.
Dress properly. Do not wear loose clothing or jewellery. Keep
your hair and clothing away from moving parts. Loose clothes,
jewellery or long hair can be caught in moving parts.
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.
Do not let familiarity gained from frequent use of machines
allow you to become complacent and ignore machine safety
principles. A careless action can cause severe injury within
a fraction of a second.
Residual risks
Even when the machine is used as prescribed it is not
possible to eliminate all residual risk factors. The following
hazards may arise in connection with the machine’s construction
and design:
Damage to lungs if an effective dust mask is not worn.
Damage to hearing if effective hearing protection is not worn.
Damages to health resulting from vibration emission if the
machine is being used over longer period of time or not
adequately managed and properly maintained.
WARNING! This machine produces an electromagnetic field
during operation. This field may under some circumstances

4
interfere with active or passive medical implants. To reduce the
risk of serious or fatal injury, we recommend persons with medical
implants to consult their physician and the medical implant
manufacturer before operating this machine.
Warning! Do not touch the blade when pruner is working to
avoid personal injury.
Wear hearing protection while operating the machine.
The declared vibration total value(s) and the declared noise
emission value(s) have been measured in accordance with a
standard test method and may be used for comparing one machine
with another.
The declared vibration total value(s) and the declared noise
emission value(s) may also be used in a preliminary assessment
of exposure.
The vibration emission and noise emissions during actual
use of the machine can differ from the declared total value
depending on the ways in which the machine is used.
There is the need to identify safety measures to protect
the operator that are based on an estimation of exposure in the
actual conditions of use (taking account of all parts of the
operating cycle such as the times when the machine is switched
off and when it is running idle in addition to the trigger time).

5
Machine use and care
Do not force the machine. Use the correct machine for your
application. The correct machine will do the job better and
safer at the rate for which it was designed.
Do not use the machine if the switch does not turn it on and
off. Any machine that cannot be controlled with the switch
is dangerous and must be repaired.
Disconnect the plug from the power source and/or remove the
battery pack, if detachable, from the machine before making
any adjustments, changing accessories, or storing machines.
Such preventive safety measures reduce the risk of starting
the machine accidentally.
Store idle machines out of the reach of children and do not
allow persons unfamiliar with the machine or these
instructions to operate the machine. Machines are dangerous
in the hands of untrained users.
Maintain machines and accessories. Check for misalignment or
binding of moving parts, breakage of parts and any other
condition that may affect the machine’s operation. If
damaged, have the machine repaired before use. Many accidents
are caused by poorly maintained machines.
Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less likely to bind
and are easier to control.
Use the machine, 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 machine
for operations different from those intended could result in
a hazardous situation.

6
Keep handles and grasping surfaces dry, clean and free from
oil and grease. Slippery handles and grasping surfaces do not
allow for safe handling and control of the machine in
unexpected situations.
Proper use of charger
Warning! Measures to reduce the risk of electric shock or
short circuit are as follows:
Please check whether the product is in good condition before
use
Do not disassemble the charger by yourself
Do not contact the output and input terminals of the charger
with metal objects；
Charge the charger with a qualified and sound outlet.

has cracks at fixed period.
Do not pull the power cord to move the charger. At the same
time, do not pull the cord to pull out the plug.
Make sure all power cords and extension cords are kept away
from water, oil and sharp edges. Make sure the power cord
doesn't get stuck in a door, fence or the place like that.
Do not use water to clean battery packs and chargers

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.
Do not use a battery pack or machine that is damaged or
modified. Damaged or modified batteries may exhibit
unpredictable behaviour resulting in fire, explosion or risk
of injury.
Do not expose a battery pack or machine to fire or excessive
temperature. Exposure to fire or temperature above 130 °C
may cause explosion.

This tool is an electric fruit tree pruner driven by lithium
battery, which consists of fixed blade, moving blade, lithium
battery, charger, toolbox and other components. Mainly applied
to the diameter of 28mm and below garden branch pruning and orchard
grafting fruit branch pruning and fruit picking. Combined with
the characteristics of safety, high efficiency and easy operation,

14
it is 8 ~ 10 times of the efficiency of traditional manual pruning,
and the pruning quality is obviously higher than that of
traditional manual pruning. When used, the blade is close to the
