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.
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.

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 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.
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 tool’s 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
burns 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.

– if the blade becomes twisted or misaligned in the cut, the
teeth at the back edge of the blade can dig into the top
surface of the wood causing the blade to climb out of the
kerf and jump back toward the operator.
Kickback is the result of saw misuse and/or incorrect
operating procedures or conditions and can be avoided by
taking proper precautions as given below.
a) Maintain a firm grip with both hands on the saw
and position your arms to resist kickback forces.
Position your body to either side of the blade,
but not in line with the blade.
Kickback could cause the saw to jump backwards,
but kickback forces can be controlled by the operator,
if proper precautions are taken.
b) When blade is binding, or when interrupting a
cut for any reason, release the trigger and hold
the saw motionless in the material until the blade
comes to a complete stop.
Never attempt to remove the saw from the work
or pull the saw backward while the blade is in
motion or kickback may occur.
Investigate and take corrective actions to eliminate
the cause of blade binding.
c) When restarting a saw in the workpiece, centre
the saw blade in the kerf and check that saw
teeth are not engaged into the material.
If saw blade is binding, it may walk up or kickback
from the workpiece as the saw is restarted.
d) Support large panels to minimise the risk of
blade pinching and kickback.
Large panels tend to sag under their own weight.
Supports must be placed under the panel on both
sides, near the line of cut and near the edge of the
panel.
e) Do not use dull or damaged blades.
Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade binding
and kickback.
f) Blade depth and bevel adjusting locking levers
must be tight and secure before making cut.
If blade adjustment shifts while cutting, it may cause
binding and kickback.
g) Use extra caution when sawing into existing
walls or other blind areas.
The protruding blade may cut objects that can cause
kickback.
Lower guard function
a) Check lower guard for proper closing before each
use. Do not operate the saw if lower guard does
not move freely and close instantly. Never clamp
or tie the lower guard into the open position.
If saw is accidentally dropped, lower guard may be
bent.
6) 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.
CIRCULAR SAW SAFETY WARNINGS
Cutting procedures
a) DANGER: Keep hands away from cutting
area and the blade. Keep your second hand on
auxiliary handle, or motor housing.
If both hands are holding the saw, they cannot be cut
by the blade.
b) Do not reach underneath the workpiece.
The guard cannot protect you from the blade below
the workpiece.
c) Adjust the cutting depth to the thickness of the
workpiece.
Less than a full tooth of the blade teeth should be
visible below the workpiece.
d) Never hold piece being cut in your hands or
across your leg. Secure the workpiece to a stable
platform.
It is important to support the work properly to minimize
body exposure, blade binding, or loss of control.
e) Hold the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting tool may contact hidden wiring.
Contact with a “live” wire will also make exposed
metal parts of the power tool “live” and could give the
operator an electric shock.
f) When ripping always use a rip fence or straight
edge guide.
This improves the accuracy of cut and reduces the
chance of blade binding.
g) Always use blades with correct size and shape
(diamond versus round) of arbour holes.
Blades that do not match the mounting hardware of
the saw will run eccentrically, causing loss of control.
h) Never use damaged or incorrect blade washers
or bolt.
The blade washers and bolt were specially designed
for your saw, for optimum performance and safety of
operation.
Kickback causes and related warnings
– kickback is a sudden reaction to a pinched, bound or
misaligned saw blade, causing an uncontrolled saw to lift
up and out of the workpiece toward the operator;
– when the blade is pinched or bound tightly by the kerf
closing down, the blade stalls and the motor reaction
drives the unit rapidly back toward the operator;

Raise the lower guard with the retracting handle and
make sure it moves freely and does not touch the
blade or any other part, in all angles and depths of cut.
b) Check the operation of the lower guard spring.
If the guard and the spring are not operating
properly, they must be serviced before use.
Lower guard may operate sluggishly due to damaged
parts, gummy deposits, or a build-up of debris.
c) Lower guard should be retracted manually
only for special cuts such as “plunge cuts” and
“compound cuts”.
Raise lower guard by retracting handle and as soon
as blade enters the material, the lower guard must be
released.
For all other sawing, the lower guard should operate
automatically.
d) Always observe that the lower guard is covering
the blade before placing saw down on bench or
floor.
An unprotected, coasting blade will cause the saw to
walk backwards, cutting whatever is in its path.
Be aware of the time it takes for the blade to stop after
switch is released.
SPECIFIC SAFETY RULES

How to make the batteries perform longer
(1) Recharge the batteries before they become
completely exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery.
If you continue to use the tool and exhaust the electric
current, the battery may be damaged and its life will
become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
use, its internal chemical substance will deteriorate,
and the battery life will be shortened. Leave the
battery and recharge it after it has cooled for a while.
CAUTION
●
When the battery charger has been continuosly
used, the battery charger will be heated, thus
constituting the cause of the failures. Once the
charging has been completed, give 15 minutes
rest until the next charging.
● If the battery is rechraged when it is warm due
to battery use or exposure to sunlight, the pilot
lamp may light in green.
The battery will not be recharged. In such a case,
let the battery cool before charging.

● When the pilot lamp flikers rapidly in red (at
0.2–second intervals), check for and take out
any foreign objects in the charger’s battery
installation hole. If there are no foreign objects,
it is probable that the battery or charger is
malfunctioning. Take it to your authorized
Service Center.
BEFORE USE
1. Check the work area environment
Check the work area to make sure that it is clear of
debris and clutter.
Clear the area of unnecessary personnel. Ensure that
lighting and ventilation is adequate.
2. Check if saw blade is tightened
While the saw blade is tightened securely for
immediate use when it is assembled at the factory, be
sure to check it out again for caution’s sake. A bolt
can be tightened when it is turned clockwise. Use the
provided box wrench to check it out.
For further details, refer to the item of [MOUNTING
AND DISMOUNTING THE SAW BLADE] on Page 16.
3. Check if wing nut is tightened
If the wing nut to adjust cutting depth (Fig. 6) is loose,
injury can result. Make sure that it is tightened
securely.
4. Check performance of lower guard
WARNING
Make absolutely sure that the lower guard is
not fixed. Also, check and see if it can move
smoothly. If the saw blade is kept exposed,
injury can result.
The lower guard (refer to Fig. 1) serves to protect your
body from coming into contact with the saw blade.
Make absolutely certain that the cover smoothly
performs to cover the saw blade. If the lower guard
should not move smoothly, never use it without
repairing it.
In such a case, get in touch with the store where
you bought the circular saw or the metabo HPT
AUTHORIZED SERVICE CENTER for necessary
repair.
5. Check battery insertion
WARNING
If the battery is inserted while the power switch
is in the ON position, the power tool will start
operating immediately, inviting serious accident.
CAUTION
Until the battery locks in place with a little click, if
not, it may accidentally fall out of the tool causing
injury to you or someone around you.
6. Check for proper operation of the brake
This circular saw features an electric brake that
functions when the switch is released. Before using
the circular saw, ensure that the electric brake
functions properly. If it does not, bring the tool to a
metabo HPT AUTHORIZED SERVICE CENTER.
7. Prepare a wooden work bench (Fig. 5)
Since the saw blade will extend beyond the lower
surface of the lumber, place the lumber on a work
bench when cutting. If a square block is utilized
as a work bench, select level ground to ensure it is
properly stabilized. An unstable work bench will result
in hazardous operation.
