Operating instructions This machine is suitable for sawing various types of wood. The machine is not designed for plunge cuts. The user bears sole responsibility for any damage caused by inappropriate use. Generally accepted accident prevention regulations and the enclosed safety information must be observed. For your own protection and for the protection of your power tool, pay attention to all parts of the text that are marked with this symbol! WARNING – Reading the operating instructions will reduce the risk of injury. Pass on your power tool only together with these documents. General Power Tool Safety Warnings WARNING – Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. Save all safety warnings and information for future reference! The term "power tool" in the safety warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

2.1 Work area safety

(62841) 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.

2.2 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 power tool. 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.

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. 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. 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.

2.4 Power tool use and care

a) Do not force the power tool. Use the correct power tool for your application. The correct

1. Specified Conditions of Use

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 with care. 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. h) Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow safe handling and control of the tool in unexpected situations.

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.

3.1 Sawing procedure

a) DANGER: Keep hands away from cutting area and the blade. Keep your second hand on auxiliary handle (5), 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 the workpiece in your hands or across your leg while cutting. Secure the workpiece to a stable platform. It is important to support the work properly to minimise body exposure, blade binding, or loss of control. e) Hold the power tool by the insulated gripping surfaces when performing an operation where the cutting accessory may contact hidden wiring or its own cord. 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 off-centre, 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.

3.2 Kickback causes and related warnings

- kickback is a sudden reaction to a pinched, jammed 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 jammed tightly by the kerf closing down, the blade stalls and the motor reaction drives the unit rapidly back toward the operator. - 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 so that the saw teeth are not engaged into the material. If a saw blade binds, 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 the 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.

3.3 Lower guard function

a) Check the lower guard for proper closing before each use. Do not operate the saw if the lower guard does not move freely and close instantly. Never clamp or tie the lower guard into the open position. If the saw is accidentally dropped, the lower guard may be bent. Raise the lower guard with the retracting handle (5) 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) The lower guard may be retracted manually only for special cuts such as "plunge cuts" and "compound cuts".Raise the lower guard by the retracting handle and as soon as the 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 the 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.

3.4 Additional Safety Instructions

Do not use abrasive wheels. Pull the plug out of the plug socket before any adjustments or servicing are performed. Keep hands away from the rotating tool! Remove chips and similar material only when the machine is at a standstill. Wear a suitable dust protection mask. Wear ear protectors. Wear protective goggles. Press the spindle locking button (3) only when the motor is at a standstill. Do not reduce the speed of the saw blade by pressing on the sides. The lower guard must not be clamped in the pulled- back position for sawing. The lower guard must move freely, automatically, easily and exactly back into its end position. When sawing materials that generate large quantities of dust, the machine must be cleaned regularly. Make sure that the safety appliances, e.g. the lower guard, are in perfect working order. Materials that generate dusts or vapours that may be harmful to health (e.g. asbestos) must not be processed. Check the workpiece for foreign bodies. When working, always make sure that no nails or other similar materials are being sawed into. If the saw blade blocks, turn the motor off immediately. Do not try to sawely small workpieces. During machining, the workpiece must be firmly supported and secured against moving. Use a saw blade that is suitable for the material being sawn. Clean gummy or glue-contaminated saw blades. Contaminated saw blades cause increased friction, jamming of the saw blade and increase the risk of back-kicks. Avoid overheating of the saw tooth tips. Avoid melting of the material when sawing plastic. Use a saw blade that is suitable for the material being sawn. Do not use saw blades made of high speed steel. Do not use saw blades which do not comply with the characteristics specifi ed in these instructions. Never use the circular saw with its lower guard fixed in the open position. Never use the circular saw with its lower guard fixed in the open position. Never operate the circular saw with the saw blade turned upward or to the side. For model KS 165, the saw blades range should be from 160 mm to 165 mm. For model KS190, the saw blades range should be from 184 mm to 190 mm. Additional Warnings: California Prop 65 08_2018 Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints,

• Crystalline silica from bricks and cement and other masonry products, and

• Arsenic and chromium from chemicallytreated lumber. Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are WARNINGENGLISH en

Always install an RCD / GFCI with a maximum trip current of 30 mA upstream. Pull the plug out of the plug socket before any adjustments or servicing are performed. Power switch Ensure that the power switch is in the OFF position. If the plug is connected to a receptacle while the power switch is in the ON position, the power tool will start operating immediately, which could cause a serious accident. Extension cord When the work area is seperated from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable. Prepare a wooden workbench Since the saw blade will extend beyond the lower surface of the lumber, place the lumber on a workbench when cutting. If a square block is utilized as a workbench, select level ground to ensure it is properly stabilized. An unstable workbench will result in hazardous operation. To avoid possible accident, always ensure that the portion of lumber remaining after cutting is securely anchored oreld in position. The hexagon wrench (9) used for attaching and detaching the saw blade (11) can be stored in the handle (24) (Fig. G).

5.1 Setting cutting depth

The cutting depth can be adjusted by moving the base after loosening its lever (A) (8) (Fig. B). Should this lever (A) (8) remain loosened, it will create a very hazardoustion. Always thoroughly clamp it.

5.2 Adjusting the angle of inclination

By loosening the wing bolt (14) at the front scale (15), the saw blade (11) can be titled up to maximum angle of 45° against the base (Fig. C). It is very hazardous to allow the wing bolt (16) to remain loosened. Always thoroughly clamp it.

5.3 Regulating the guide

The cutting position can be regulated by moving the base (7) after loosening its wing bolt (16) (Fig. C). The base can be mounted on either the left or the right side. It is advisable to set the depth of cut in such a way that no more than half of each tooth on the saw blade juts out under the workpiece. See illustration on page 2.

5.4 Setting extraction nozzle

Thread the nose (25) on the front of the extraction nozzle (6) on the housing of the saw (Fig. G). Tighten the extraction nozzle to the saw housing with the screw (26) provided. Sawdust extraction To extract the sawdust, connect a suitable extraction unit with suction hose to the machine.

6.1 Switching on and off

Switching on: Press and hold locking button (3) and than the trigger (2). Switching off: Release locking button (3) and the trigger (2).

5. Initial Operation, Setting

6.2 Working Directions

Lay out the mains cable such that the cut can be executed without obstruction. Place the base (7) on the lumber, and align the cutting line with the saw blade at the front scale (15). Turn ON the trigger (2) before the saw blade contacts the lumber. CAUTIONS Prior to cutting operation, make sure the material you are going to cut. If the material to be cut is expected to generate harmful / toxic dusts, make sure the dust bag or appropriate dust extraction system is connected with dust outlet tightly. Wear the dust mask additionally. When finished with a job, pull out the plug from the receptacle. Do not switch the machine on or off while the saw blade is touching the workpiece. Let the saw blade reach its full speed before making a cut. When the hand-held circular saw is added, the lower guard is swung backwards by the workpiece. When sawing, never remove the machine from the material with the saw blade turning. Allow the saw blade to come to a standstill. If the saw blade blocks, turn the machine off immediately.

1. Changing saw blades

Pull the plug out of the plug socket before any adjustments or servicing are performed. Use only sharp, undamaged saw blades. Do not use saw blades that are cracked or that have changed their shape. Do not use any saw blades which do not conform to the specified rating. Use only saw blades with a diameter according to the markings on the saw. The saw blade must be suitable for the no-load speed. Use a saw blade that is suitable for the material being sawn. Use only genuine Metabo - saw blades. To avoid serious accident, ensure the switch is in the OFF position, and the power source is disconnected. Dismounting the saw blade (Fig. F)

1. Depress the lock lever (19), lock the spindle (22),

and remove the hexagonal-socket bolt (18) with the hexagon wrench (9).

2. While holding the lower guard lever (13) to keep

the lower guard fully retracted into the saw cover, remove the saw blade. Mounting the Saw Blade(Fig. F) 1.Thoroughly remove any sawdust which has accumulated on the spindle, bolt and washers.

2. As shown in Fig. E, the side of Washer (A) (21)

with a projected center the same diameter as the inner diameter of the saw blade (11) and the concave side of Washer (B) (20) must be fitted to the saw blade.

3. To assure proper rotation direction of the saw

blade (11), the arrow direction on the saw blade must coincide with the arrow direction on the saw cover.

4. Using the fingers, tighten the hexagonal-socket

bolt (18) retaining the saw blade as much as possible. Then depress the lock lever (19), lock the spindle (22), and thoroughly tighten the hexagonal- socket bolt (18). After having attached the saw blade, reconfi rm that the lock lever is firmly secured in the prescribed position.

5. Inspecting the saw blade Since use of a dull saw

blade will degrade efficiency and cause possible motor malfunction, sharpen or replace the saw blade as soon as abrasion is noted.

6. Inspecting the mounting screws Regularly

inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could result in serious hazard.

7. Maintenance of the motor. The motor unit winding

is the very “heart” of the power tool. Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.

8. Inspecting the carbon brushes For your

continued safety and electrical shock protection, carbon brush inspection and replacement on this tool should ONLY be performed by a Metabo authorized service center.

9. Adjusting the base (7) and saw blade (11) to

maintain perpendicularity. The angle between the base and the saw blade has been adjusted to 90°, however should this perpendicularity be lost for some reason, adjust in the following manner:

2. Apply a square to the base (7) and the saw blade

(11) and turning the slotted set screw (23) with a slotted-head screwdriver, shift the position of the base to produce the desired right angle Dust deposits must be regularly removed from the machine. This includes vacuum cleaning the ventilation louvres on the motor. Make sure that the safety appliances, e.g. the lower guard, are in perfect working order. The lower guard must move freely, automatically, easily and exactly back into its end position.
