1) Work area safety
a) Keep work area clean and well lit.
Cluttered or 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.
f) 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.
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 a dust mask, non-
skid safety shoes, hard hat or hearing protection
used for appropriate conditions will reduce
personal injuries.
c) 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.
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.

dust extraction and collection facilities, ensure
these are connected and properly used.
Use of dust collection can reduce dust-related
hazards.
h) 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.
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 remove the battery pack, if detachable,
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 and accessories. Check
for misalignment or binding of moving parts,
breakage of parts and any other condition
that may affect the power toolʼs 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.
h) 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 tool in
unexpected situations.
5) Service
a) 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.
PRECAUTION
Keep children and infirm persons away.
When not in use, tools should be stored out of reach
of children and infirm persons.
SAFETY INSTRUCTIONS FOR MITER SAWS
a) Miter saws are intended to cut wood or wood-like
products, they cannot be used with abrasive cut-
offwheels for cutting ferrous material such as
bars, rods, studs, etc.
Abrasive dust causes moving parts such as the lower
guard to jam. Sparks from abrasive cutting will burn
the lower guard, the kerf insert and other plastic parts.
b) Use clamps to support the workpiece whenever
possible. If supporting the workpiece by hand,
you must always keep your hand at least 100 mm
from either side of the saw blade. Do not use this
saw to cut pieces that are too small to be securely
clamped or held by hand.
If your hand is placed too close to the saw blade, there
is an increased risk of injury from blade contact.
c) The workpiece must be stationary and clamped
or held against both the fence and the table.
Do not feed the workpiece into the blade or cut
"freehand" in any way.
Unrestrained or moving workpieces could be thrown
at high speeds, causing injury.
d) Never cross your hand over the intended line of
cutting either in front or behind the saw blade.
Supporting the workpiece “cross handed” i.e. holding
the workpiece to the right of the saw blade with your
left hand or vice versa is very dangerous.
e) Do not reach behind the fence with either hand
closer than 100 mm from either side of the saw
blade, to remove wood scraps, or for any other
reason while the blade is spinning.
The proximity of the spinning saw blade to your hand
may not be obvious and you may be seriously injured.
f) Inspect your workpiece before cutting. If the
workpiece is bowed or warped, clamp it with the
outside bowed face toward the fence. Always
make certain that there is no gap between the
workpiece, fence and table along the line of the
cut.
Bent or warped workpieces can twist or shift and
may cause binding on tile spinning saw blade while
cutting. There should be no nails or foreign objects in
the workpiece.
g) Do not use the saw until the table is clear of all
tools, wood scraps, etc., except for the workpiece.
Small debris or loose pieces of wood or other objects
that contact the revolving blade can be thrown with
high speed.
h) Cut only one workpiece at a time.
Stacked multiple workpieces cannot be adequately
clamped or braced and may bind on the blade or shift
during cutting.
i) Ensure the miter saw is mounted or placed on a
level, firm work surface before use.
A level and firm work surface reduces the risk of the
miter saw becoming unstable.
j) Plan your work. Every time you change the bevel
or miter angle setting, make sure the adjustable
fence is set correctly to support the workpiece and
will not interfere with the blade or the guarding
system.

English
Without turning the tool “ON” and with no workpiece
on the table, move the saw blade through a complete
simulated cut to assure there will be no interference or
danger of cutting the fence.
k) Provide adequate support such as table
extensions, saw horses, etc. for a workpiece that
is wider or longer than the table top.
Workpieces longer or wider than the miter saw table
can tip if not securely supported. If the cut-offpiece or
workpiece tips, it can lift the lower guard or be thrown
by the spinning blade.
l) Do not use another person as a substitute for a
table extension or as additional support.
Unstable support for the workpiece can cause the
blade to bind or the workpiece to shift during the
cutting operation pulling you and the helper into the
spinning blade.
m) The cut-offpiece must not be jammed or pressed
by any means against the spinning saw blade.
If confined, i.e. using length stops, the cut-offpiece
could get wedged against the blade and thrown
violently.
n) Always use a clamp or a fixture designed to
properly support round material such as rods or
tubing.
Rods have a tendency to roll while being cut, causing
the blade to "bite" and pull the work with your hand
into the blade.
o) Let the blade reach full speed before contacting
the workpiece.
This will reduce the risk of the workpiece being
thrown.
p) If the workpiece or blade becomes jammed, turn
the miter saw off. Wait for all moving parts to stop
and disconnect the plug from the power source
and/or remove the battery pack. Then work to free
the jammed material.
Continued sawing with a jammed workpiece could
cause lass of control or damage to the miter saw.
q) After finishing the cut, release the switch, hold
the saw head down and wait for the blade to stop
before removing the cut-offpiece.
Reaching with your hand near the coasting blade is
dangerous.
r) Hold the handle firmly when making an incomplete
cut or when releasing the switch before the saw
head is completely in the down position.
The braking action of the saw may cause the saw
head to be suddenly pulled downward, causing a risk
of injury.
s) When the saw head is in the down position, never
release the hand that is gripping the handle.
Doing so could snap the saw head up, forcing the tool
to fall and possibly cause injury.

8. Confirm the tool’s power cord is not damaged.
Repair or replace the power cord if an inspection indicates that it is damaged
9. Eye protection
Always wear eye protection with side shields that meets the requirements of ANSI Standard
Z87.1. Ordinary eyeglasses do not provide adequate protection because they do not contain
impact resistant safety glass.
WARNING: Operating the tool without wearing proper eye protection may
result in serious injury.
10. Electric brake
This tool is equipped with an electric brake which will typically stop the blade within
5 seconds after the trigger switch is released.
Occasionally, there will be a delay in the brake engaging which will result in a longer blade
stopping time. On rare occasions, the brake may not engage at all and the saw blade will
coast to a stop.
If the brake fails to engage frequently, depress and release the trigger switch to turn the
tool on and off4 or 5 times. If the brake still does not engage, have the tool serviced at a
metabo HPT authorized service center.
Always confirm that the saw blade has completely stopped before raising it from the
workpiece.
The brake is not a substitute for a properly functioning lower guard. Check the function of
the lower guard before each use. Serious personal injury may occur if the lower guard does
not move smoothly and cover the blade properly.
WARNING: Please be aware of the reaction of the Motor Head (Fig. 1) when
the brake is activated. Braking causes the Motor Head to jerk
downward and the user should be prepared for this reaction,
especially when the trigger switch is released before the blade is
completely down. Failure to be familiar with, and prepared for, the
operational characteristics of the tool may cause serious injury.
AFTER CONNECTING THE POWER PLUG TO AN APPROPRIATE AC
POWER SOURCE, CHECK THE OPERATION OF THE TOOL AS FOLLOWS:
11. Trial Run
After confirming that no one is standing behind, the power tool start and confirm that no
operating abnormalities exist before attempting a cutting operation.
12. Inspect the rotating stability of the saw blade.
For precise cutting, rotate the saw blade and check for deflection to confirm that the blade
is not noticeably unstable; otherwise vibrations might occur and cause an accident.
