Frequently Asked Questions - K 535i HUSQVARNA

How do I change the cutting blade on the Husqvarna K 535i?

Remove the battery. Use the combination wrench to lock the shaft. Unscrew the coupling flange, replace the blade, then tighten the bolt to a torque of 30 Nm (18.5 ft-lb). Ensure the blade is suitable (abrasive or diamond) and not damaged.

Can I use the cutter without water?

Yes, you can cut dry. However, for diamond blades, water cools the blade and reduces dust. When cutting dry, it is recommended to remove the blade from the cut every 30 to 60 seconds and let it spin freely for 10 seconds to cool down.

What is the battery runtime?

The runtime depends on the battery and usage. With the BLi300 (9.4 Ah) battery, you can cut for about 30 to 40 minutes in continuous use. The SavE function reduces speed to extend runtime.

How do I activate the SavE function?

Press the SavE button on the keypad. The green LED lights up to indicate the function is active. Press again to deactivate. This function reduces the blade speed without reducing cutting power.

What should I do if the warning indicator flashes?

Flashing can indicate an overload or abnormal temperature. Let the product cool down, clean the cutting equipment, and release the trigger. If the problem persists, contact your service workshop.

What blades can I use?

Use only diamond or abrasive blades designed for portable cutters, with a maximum diameter of 230 mm. Do not use serrated blades or blades with segments spaced more than 10 mm. Ensure the rated blade speed is at least 5940 rpm.

How do I maintain the Husqvarna K 535i?

Before each use, check the condition of the blade, guards, and trigger. Clean the fan housing weekly. Use compressed air to clean the battery and charger. Follow the maintenance schedule in the manual.

What protective equipment should I wear?

Always wear a safety helmet, a dust mask, ear protectors, safety glasses, thick gloves, and steel-toed boots. A first aid kit should be available.

How do I store the machine and battery?

Remove the battery. Store the machine in a dry place, protected from frost. The battery should be stored between 5 °C and 25 °C, away from sunlight. Charge it between 30% and 50% before prolonged storage. Do not leave the battery in a damp or metal place.

Can I use the K 535i to cut plastic pipes?

No, do not use a diamond blade on plastic materials. The heat would melt the plastic, which could stick to the blade and cause kickback. Use the product only for recommended materials: tiles, slabs, lightweight concrete.

Safety definitions

Warnings, cautions and notes are used to point out specially important parts of the manual.

WARNING: Used if there is a risk of injury or death for the operator or bystanders if the instructions in the manual are not obeyed.

CAUTION: Used if there is a risk of damage to the product, other materials or the adjacent area if the instructions in the manual are not obeyed.

Note: Used to give more information that is necessary in a given situation.

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.

Note: Save all warnings and instructions for future reference. The term "power tool" in the warnings refers to your mains-operated (cored) power tool or battery-operated (cordless) power tool.

Work area safety

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• 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.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety

• 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.

• 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.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
• 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.
• 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.
• If operating a power tool in a damp location is unavoidable, use a residual circuit interrupter (RCD) protected supply. Use of a RCD reduces the risk of electric shock

CAUTION: Do not pressure wash the machine, as water can enter the electrical system or the engine and cause damage to the machine or short circuit.

Personal safety

• 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.
• 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.

• Prevent unintentional starting. Ensure the switch is in the OFF-position before connecting to a 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.

• 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.

• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
• 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.
• 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.
• The vibration emission during actual use of the power tool can differ from the declared total value depending on the ways in which the tool is used. Operators should identify safety measures to protect themselves 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).
• Remain at a distance from the blade when the engine is running.

Power tool use and care

• 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.
• 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.
• 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.
• 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.
• 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.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
• 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.

• Under no circumstances should you modify the original design of the machine without approval from the manufacturer. Always use original spare parts. Unauthorized modifications and/or accessories may lead to serious injury or death to the user or others.
• Make sure that no pipes or electrical cables are routed in the working area or in the material to be cut.
• Always check and mark out where gas pipes are routed. Cutting close to gas pipes always entails danger. Make sure that sparks are not caused when cutting in view of the risk of explosion. Remain concentrated and focused on the task. Carelessness can result in serious personal injury or death.

Battery tool use and care

• 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.
• Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
• 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.
• 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 irritations or burns.

Service

• 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.

Cut-off machine safety warning

• The guard provided with the tool must be securely attached to the power tool and positioned for maximum safety so the least amount of wheel is exposed towards the operator. Position yourself and bystanders away from the plane of the rotating wheel. The guard helps to protect operator from broken wheel fragments and accidental contact with the wheel.

• Use only bonded reinforced or diamond cut-off wheels for your power tool. Just because an accessory can be attached to your power tool, it does not assure safe operation.

• The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories running faster than their rated speed can break and fly apart.

• Wheels must be used only for recommended applications. For example, do not grind with the side of the cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to these wheels may cause them to shatter.
• Always use undamaged wheel flanges that are of correct diameter for your selected wheel. Proper wheel flanges support the wheel thus reducing the possibility of wheel breakage.
• Do not use worn down reinforced wheels from larger power tools. Wheels intended for a larger power tool are not suitable for the higher speed of a smaller tool and may burst.
• The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled.
• The arbour size of wheels and flanges must properly fit the spindle of the power tool. Wheels and flanges with arbour holes that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control.
• Do not use damaged wheels. Before each use, inspect wheels for chips and cracks. If power tool or wheel is dropped, inspect for damage or install an undamaged wheel. After inspecting and installing the wheel, position yourself and bystanders away from the plane of the rotating wheel and run the power tool at maximum no load speed for one minute. Damaged wheels will normally break apart during this test time.
• Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and shop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping flying debris generated by various operations. The dust mask or respirator must be capable of filtrating particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.
• Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpiece or a broken wheel may fly away and cause injury beyond immediate area of operation.
• Hold the power tool by insulated gripping surfaces only, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.
• Never lay the power tool down until the accessory has come to a complete stop. The

spinning wheel may grab the surface and pull the power tool out of your control.

• Do not run the power tool while carrying it at your side. Accidental contact with the spinning accessory could snag your clothing, pulling the accessory into your body.
• Regularly clean the power tool's air vents. The motor's fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards.
• Do not operate the power tool near flammable materials. Sparks could ignite these materials.

Kickback and related warnings

• Kickback is a sudden reaction to a pinched or snagged rotating wheel. Pinching or snagging causes rapid stalling of the rotating wheel which in turn causes the uncontrolled power tool to be forced in the direction opposite of the wheel's rotation at the point of the binding.
• For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The wheel may either jump toward or away from the operator, depending on direction of the wheel's movement at the point of pinching. Abrasive wheels may also break under these conditions.
• Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below.
• Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. Always use auxiliary handle, if provided, for maximum control over kickback or torque reaction during start-up. The operator can control torque reactions or kickback forces, if proper precautions are taken.
• Never place your hand near the rotating accessory. Accessory may kickback over your hand.
• Do not position your body in line with the rotating wheel. Kickback will propel the tool in direction opposite to the wheel's movement at the point of snagging.
• Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause loss of control or kickback.
• Do not attach a saw chain, woodcarving blade, segmented diamond wheel with a peripheral gap greater than 10mm or toothed saw blade. Such blades create frequent kickback and loss of control.
• Do not "jam" the wheel or apply excessive pressure. Do not attempt to make an excessive depth of cut. Overstressing the wheel increases the

loading and susceptibility to twisting or binding of the wheel in the cut and the possibility of kickback or wheel breakage.

• When wheel is binding or when interrupting a cut for any reason, switch off the power tool and hold the power tool motionless until the wheel comes to a complete stop. Never attempt to remove the wheel from the cut while the wheel is in motion otherwise kickback may occur. Investigate and take corrective action to eliminate the cause of wheel binding.
• Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully re-enter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece.
• Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback. Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece near the line of cut and near the edge of the workpiece on both sides of the wheel.
• Use extra caution when making a "pocket cut" into existing walls or other blind areas. The protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.

Assembly

Applicable cutting blades

Cutting blades for Husqvarna K 535i are available in two basic models: abrasive blades and diamond blades.

Cutting blades for handheld high speed power cutters

WARNING: Only use diamond blades and abrasive blades for concrete. Do not use blades with serrations such as circular wood cutting blades or blades with carbide tips. The risk of kickback is increased and carbide tips can come off and be thrown at high speed. This can result in injury or death.

WARNING: Incorrect use can cause the blade to become too hot. A blade that is too hot can cause malfunction, which can cause damage and injury.

WARNING: Do not use a cutting blade with a lower maximum speed than that of the power cutter. Only use cutting blades that

are in compliance with national or regional standards.

Note: Only cut materials approved in the instruction supplied with the blade.

Check that the blade is approved for the same or higher speed written on the type plate of the power cutter.

Blade vibration

CAUTION: If you use the product with too much force, the blade can get too hot, bend and cause vibrations. Use the product with less force. If the vibrations continue, replace the blade.

Abrasive blades

WARNING: Do not use abrasive blades with water. The strength is impaired when abrasive blades are exposed to water or moisture, which results in an increased risk of the blade breaking.

CAUTION: Cutting with abrasive blade is not allowed with the Vac attachment. Use of abrasive blades causes unnatural wear on the Vac attachment.

CAUTION: Do not use abrasive blades with thickness exceeding maximum recommended thickness, refer to Technical data on page 22

• Do not use worn reinforced wheels from larger power tools. Wheels intended for a larger power tool are not suitable for the higher speed of a smaller tool and may burst.
• The cutting material on abrasive blades consists of a grit bonded agent using an organic binder. Reinforced blades are made up of a fabric or fibre base that prevents total breakage at maximum working speed if the blade should be cracked or damaged.
• A cutting blade's performance is determined by the type and size of abrasive corn, and the type and hardness of the bonding agent.
• Ensure the cutting blade is not cracked or damaged.

• Test the abrasive blade by hanging it on your finger and tapping it lightly with a screwdriver or the like. If the blade does not produce a resonant, ringing sound it is damaged.

• Ensure that correct abrasive blade is used on the intended material.

Diamond blades

WARNING: Never use a diamond blade to cut plastic material. The heat produced during cutting may melt the plastic and it can stick to the cutting blade and cause a kickback.

WARNING: Diamond blades become very hot when used. An overheated blade is a result of improper use, and may cause deformation of the blade, resulting in damage and injuries.

Note: Sharpen the blade by cutting soft material such as sandstone or block.

Always use a sharp diamond blade.
- Diamond blades can become dull when the wrong feeding pressure is used or when cutting certain materials such as heavily reinforced concrete. Working with a dull diamond blade causes overheating, which can result in the diamond segments coming loose.
- Diamond blades consist of a steel core provided with segments that contain industrial diamonds.
- Diamond blades are ideal for masonry, concrete and other composite materials.
- When using diamond blade make sure that it rotates in the direction indicated by the arrow on the blade.

Wet cutting

CAUTION: Do not use Vac equipment together with the wet system.

• Diamond blades for wet cutting must be used with the wet system.
  Water cool the blade and increases its service life while also decrease the dust.
• When wet cutting, make sure to collect the waste water safely.

Dry cutting

• When dry cutting, lift the blade out from the cut each 30-60 seconds and let it rotate in the air for 10 seconds to let it cool.
• Use Vac equipment if possible.

Diamond blade - requirements

WARNING: Make sure the diamond segment (T1) is wider than the blade (T2). This is to prevent pinching in the cutting slot and a kickback.

WARNING: Do not use the side of the blade. The blade can become damaged and broken, which can cause an injury. Use only the cutting edge.

WARNING: Do not use a diamond blade to cut plastic material. The heat that occurs can melt the plastic. Melted plastic can attach to the cutting blade and cause a kickback.

The product is made for high speed diamond blades approved for handheld power cutters.
- The product is made to cut in to tiles, light concrete and stone. Use only for this type of operation.
- Make sure that the cutting blade does not show signs of damage and that it is attached correctly, see Abrasive blades on page 10 and To attach the cutting blade on page 13.
Make sure to use the correct cutting blade for the type of operation, see Cutting blades for handheld high speed power cutters on page 10.
- Do not cut asbestos material.
- Always hold the power cutter with 2 hands. Always hold the product tightly with thumbs and fingers around the handles. Always hold the rear handle with the right hand and the front handle with the left hand.

• Always be parallel to the cutting blade. Do not be linearly behind the cutting blade. If there is a kickback, the power cutter moves in the plane of the cutting blade.

• Keep a safe distance to the cutting blade when the engine operates.
  Make sure that you are in a stable position during operation.
• Keep applicable distance from the object you are cutting.
• Do not operate above shoulder height. Use a platform or scaffold if the cutting operation is above shoulder height. Do not overreach.
• Do not operate from a ladder.

Make sure that the cutting blade is free when the engine is started.
- Always monitor the product when the engine operates.

spray and dust and moves them away from the operator.

kickbacks and how to prevent them before you use the product.

• Cut with full throttle. Keep full rotating speed until the cutting operation is completed.
• Push the cutting blade lightly against the object you are cutting. Do not use force.
• Align the cutting blade with the cut.

• Move the cutting blade slowly forward and rearward to decrease the area between the cutting blade and the material. This decreases the temperature of the cutting blade.

• Do not cut with the kickback zone of the blade, see Kickback on page 17.

Kickback

WARNING: Kickbacks are sudden and can be very dangerous. The product can be moved up and rearward in the direction of the operator in a rotating movement. Injury or death is a possible result of a kickback. Make sure you understand the causes of

A kickback occurs when the blade is pinched in the kickback zone. Usually they are not dangerous but a strong kickback can cause injury or death.

Reactive force

• A reactive force pulls the product in the opposite direction of the blade movement. Most of the time this force is not strong. If the blade is pinched the strength of the reactive force can cause a kickback.

• Do not tilt the product when the cutting equipment rotates. Centrifugal forces can decrease movement.

Kickback zone

• Do not cut with the kickback zone of the cutting blade. If the blade is pinched in the kickback zone, the reactive force rotates the product up and back. It can hit the operator and can result in injury or death.

Climbing kickback,

• Do not use the kickback zone. When the kickback zone is used for cutting, the reactive force moves the

blade up into the cut. Use the lower part of the blade to prevent climbing kickback.

Pinching kickback

• A blade is pinched when the cut closes and stops the turning of the blade. If the blade is pinched, the strength of the reactive force can cause loss a kickback.

• Make sure that the work piece is held to keep the cut open during a cutting operation. Make an estimate of the possible movement of the work piece during last phase of the cutting operation. Make sure that the cut opens during the cutting operation. A cut that closes can cause a pinching kickback.

To cut into pipes

WARNING: If the blade is pinched in the kickback zone it will cause a kickback.

Be careful when cutting in pipes. The pipe is must kept in place correctly and the cut kept open through out the cutting. If not, the blade can be pinched. Be especially careful when cutting a pipe with a bell end or a pipe in a ditch. If it does not have correct support the blade can be pinched.

1. Make sure the pipe does not move during cutting.

1. Cut with section "l".

1. Make sure that the cut opens to prevent pinching.

1. Move to side II and cut from section I to the bottom of the pipe.
2. Move to side III and cut the remaining part of the pipe.
3. Make sure the pipe is kept in place correctly. The end of the pipe must move down during the cutting.

To prevent pinching

WARNING: Do not let the cut close during a cutting operation. A cut that closes can cause pinching, which can cause a kickback or damage to the cutting blade.

WARNING: Be careful when the cutting blade is put in a cut that was there before.

• Make sure that the work piece cannot move during a cutting operation.

• Make sure that the work piece is held to keep the cut open during a cutting operation.

• Make an estimate of the possible movement of the work piece during the last phase of the cutting operation.

• Make sure that the cut opens during the cutting operation.

To manage dust

• The product has a low flushing water kit. Use wet cutting when possible. See instructions in To connect coolant water on page 15. The correct flow is different for different types of tasks. If the water hose comes off at the supply source, the supplied water pressure can be too high. See Technical data on page 22 for recommended water pressure.
• Adjust the water flow with the valve.
