• Disconnect the machine from the mains before carrying out any maintenance work or when
changing theblade.
• Never perform any cleaning or maintenance work when the machine is still running and the
head is not in the restposition.
• When fitted with LED, no exchange with different type of LED permitted. Repairs shall only be
carried out by the manufacturer or an authorized agent.
• Connect the saw to a dust collection device when sawing wood. Always consider factors
which influence exposure of dust suchas:
ʵ type of material to be machined (chip board produces more dust than wood);
ʵ sharpness of the saw blade;
ʵ correct adjustment of the saw blade,
ʵ dust extractor with air velocity not less than 20 m/s.
Ensure that the local extraction as well as hoods, baffles and chutes are properlyadjusted.
• Please be aware of the following factors influencing exposure
tonoise:
ʵ use saw blades designed to reduce the emitted noise;
ʵ use only well sharpened saw blades;
• Machine maintenance shall be conducted periodically;
• Provide adequate general or localized lighting;
• Ensure the operator is adequately trained in the use, adjustment and operation of the
machine;
• Ensure that any spacers and spindle rings are suitable for the purpose as stated in
thismanual.
• Refrain from removing any cut-offs or other parts of the workpiece from the cutting area while
the machine is running and the saw head is not in the rest position
• Never cut workpieces shorter than 150mm.
• Without additional support the machine is designed to accept the maximum workpiece
sizeof:
ʵ Height 60mm by width 270mm by length 500mm
ʵ Longer workpieces need to be supported by suitable additional table, e.g. DE7023. Always
clamp the workpiecesafely.
• In case of an accident or machine failure, immediately turn the machine off and disconnect
machine from the powersource.
• Report the failure and mark the machine in suitable form to prevent other people from using
the defectivemachine.
• When the saw blade is blocked due to abnormal feed force during cutting, turn the machine
off and disconnect it from power supply. Remove the workpiece and ensure that the saw
blade runs free. Turn the machine on and start new cutting operation with reduced feedforce.
• Never cut light alloy, especiallymagnesium.
• Whenever the situation allows, mount the machine to a bench using bolts with a diameter of
8mm and 80mm inlength.
Residual Risks
The following risks are inherent to the use ofsaws:
• injuries caused by touching the rotating parts
In spite of the application of the relevant safety regulations and the implementation of safety
devices, certain residual risks cannot be avoided. Theseare:
• Impairment ofhearing.
• Risk of accidents caused by the uncovered parts of the rotating sawblade.
• Risk of injury when changing the unprotected sawblade.
• Risk of squeezing fingers when opening theguards.
• Health hazards caused by breathing dust developed when sawing wood, especially oak,
beech andMDF.
The following factors increases the risk of breathingproblems:
• No dust extractor connected when sawing wood
• Insufficient dust extraction caused by uncleaned exhaust filters

13 . Do notoverreach.
Keep proper footing and balance at alltimes.
14 . Maintain tools withcare.
Keep cutting tools sharp and clean for better and safer performance. Follow instructions for
lubricating and changing accessories. Inspect tools periodically and if damaged have
them repaired by an authorized service facility. Keep handles
and switches dry, clean and free from oil andgrease.
15 . Disconnecttools.
When not in use, before servicing and when changing accessories such as blades, bits and
cutters, disconnect tools from the powersupply.
16 . Remove adjusting keys andwrenches.
Form the habit of checking to see that adjusting keys and wrenches are removed from the tool
before operating thetool.
17 . Avoid unintentionalstarting.
Do not carry the tool with a finger on the switch. Be sure that the tool is in the “off” position
before pluggingin.
18 . Use outdoor extensionleads.
Before use, inspect the extension cable and replace if damaged. When the tool is used
outdoors, use only extension cords intended for outdoor use and markedaccordingly.
19 . Stayalert.
Watch what you are doing. Use common sense. Do not operate the tool when you are tired or
under the influence of drugs oralcohol.
20 . Check for damagedparts.
Before use, carefully check the tool and mains cable to determine that it will operate properly
and perform its intended function. Check for alignment of moving parts, binding of moving
parts, breakage of parts, mounting and any other conditions that may affect its operation. A
guard or other part that is damaged should be properly repaired or replaced by an authorized
service centre unless otherwise indicated in this instruction manual. Have defective switches
replaced by an authorized service centre.
Do not use the tool if the switch does not turn it on and off.
Never attempt any repairsyourself.

WARNING! The use of any accessory or attachment or performance of any operation
with this tool other than those recommended in this instruction manual may present a
risk of personalinjury.
21 . Have your tool repaired by a qualifiedperson.
This electric tool complies relevant safety rules. Repairs should only be carried out by qualified
persons using original spare parts; otherwise this may result in considerable danger to
theuser.
Additional Safety Rules for Mitre Saws
• The machine is provided with a special configured power supply cord which can only be
replaced by the manufacturer or its authorised serviceagent.
• Do not use the saw to cut other materials than those recommended by themanufacturer.
• Do not operate the machine without guards in position, or if guards do not function or are not
maintainedproperly.
• Ensure that the arm is securely fixed when performing bevelcuts.
• Keep the floor area around the machine level, well-maintained and free of loose materials,
e.g., chips and cut-offs.
• Select the correct blade for the material to becut.
• Use correctly sharpened saw blades. Observe the maximum speed mark on the sawblade.
• Make sure all locking knobs and clamp handles are tight before starting anyoperation.
• Never place either hand in the blade area when the saw is connected to the electrical
powersource.
• Never attempt to stop a machine in motion rapidly by jamming a tool or other means against
the blade; serious accidents canoccur.
• Before using any accessory consult the instruction manual.
The improper use of an accessory can causedamage.
• Use a holder or wear gloves when handling a saw blade or roughmaterial.
• Ensure that the saw blade is mounted correctly beforeuse.
• Make sure that the blade rotates in the correctdirection.
• Do not use blades of larger or smaller diameter than recommended. For the proper blade
rating refer to the technical data. Use only the blades specified in this manual, complying
with EN847-1.
• Consider applying specially designed noise-reductionblades.
• Do not use HIGH SPEED STEELblades.
• Do not use cracked or damaged sawblades.
• Do not use any abrasive or diamonddiscs.
• Use only saw blades where the marked speed is at least equal to the speed marked on thesaw.
• Never use your saw without the kerfplate.
• Raise the blade from the kerf in the workpiece prior to releasing theswitch.
• Before each cut ensure that the machine isstable.
• Do not wedge anything against the fan to hold the motorshaft.
• The blade guard on your saw will automatically raise when the arm is brought down; it will
lower over the blade when head lock up release lever
2
ispushed.
• Never raise the blade guard manually unless the saw is switched off. The guard can be raised
by hand when installing or removing saw blades or for inspection of thesaw.
• Check periodically that the motor air slots are clean and free ofchips.
• Replace the kerf plate whenworn.
