Symbols
The following show the symbols used for the equipment.
Be sure that you understand their meaning before use.
･Read instruction manual.
･Only for EU countries
Do not dispose of electric equipment
together with household waste material!
In observance of European Directive

ENE062-1
Intended use
The tool is intended for cutting mortise in wood.
ENF001-1
Power supply
The tool should be connected only to a power supply of
the same voltage as indicated on the nameplate, and
can only be operated on single-phase AC supply. This
tool should be grounded while in use to protect the
operator from electric shock. Use only three-wire
extension cords which have three-prong grounding-type
plugs and three-pole receptacles which accept the tool's
plug.
ENG905-1
Noise
The typical A-weighted noise level determined according
to EN61029:
Sound pressure level (LpA) : 90 dB(A)
Sound power level (LWA) : 103 dB(A)
Uncertainty (K) : 3 dB(A)
Wear ear protection
ENG900-1
Vibration
The vibration total value (tri-axial vector sum)
determined according to EN61029:
Vibration emission (ah) : 2.5 m/s2or less
Uncertainty (K) : 1.5 m/s2
ENG901-1
• The declared vibration emission value has been
measured in accordance with the standard test
method and may be used for comparing one tool
with another.
• The declared vibration emission value may also be
used in a preliminary assessment of exposure.
WARNING:
• The vibration emission during actual use of the
power tool can differ from the declared emission
value depending on the ways in which the tool is
used.
• Be sure 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 tool is switched off and when it
is running idle in addition to the trigger time).

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, fire and/or
serious injury.
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
(cordless) power tool.
Work area safety
1. Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
2. 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.
3. Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
Electrical safety
4. 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.
5. 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.
6. Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
7. 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.
8. 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.
9. 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.
10. Use of power supply via a RCD with a rated
residual current of 30mA or less is always
recommended.
Personal safety
11. 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.
12. 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.
13. 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.
14. 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.
15. Do not overreach. Keep proper footing and
balance at all times. This enables better control

4
of the power tool in unexpected situations.
16. 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.
17.
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.
Power tool use and care
18. 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.
19. 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.
20. 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.
21. 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.
22. Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
23. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
24. 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.
Service
25. Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
26. Follow instruction for lubricating and
changing accessories.
27. Keep handles dry, clean and free from oil and
grease.
ENB093-1
ADDITIONAL SAFETY RULES
1. Use this tool only to cut holes in wood.
2. This tool is for cutting holes in flat-surfaced
wood. Never use it for cutting holes in a log.
3. Wear ear protectors.
4. Handle the cutter chain carefully; it is very
sharp.
5. Place the workpiece on wood blocks or short
beams to prevent the cutter chain from hitting
the ground, floor, etc., causing damage to the
cutter chain at the time of hole breakthrough.
6. Check the cutter chain carefully for cracks or
damage before operation.
Replace cracked or damaged cutter chain
immediately.
7. Secure the tool to the workpiece firmly.
8. Inspect for and remove nails or foreign matter
from the workpiece before operation.
9. Do not operate the tool with the safety cover
open.
10. Do not wear gloves during operation.
11. Keep hands away from moving parts.
12. Remove the tool from the workpiece after
operation to keep it from falling off and
possibly causing injury.
13. Do not abuse cord. Never yank cord to
disconnect it from the receptacle. Keep cord
away from heat, oil, water and sharp edges.
14. PROPER GROUNDING. This tool should be
grounding while in use to protect the operator
from electric shock.
15. EXTENSION CORDS. Use only three-wire
extension cords which have three-prong
grounding-type plugs and three-pole
receptacles which accept the tool’s plug.
Replace or repair damaged or worn cord
immediately.
SAVE THESE INSTRUCTIONS.
