To start a Husqvarna K760 disc cutter, follow these steps:
Before starting:
With a cold engine:
With a warm engine:
The correct fuel mix ratio is 1:50 (2%) with HUSQVARNA two-stroke oil or equivalent. For other oils, the ratio is 1:33 (3%) with oils class JASO FB or ISO EGB formulated for air-cooled, two-stroke engines, or as per the oil manufacturer's recommendation. It is important to accurately measure the amount of oil to ensure the correct mixture.
Yes, the Husqvarna K760 is designed to cut hard materials like masonry or steel. Diamond blades are ideal for masonry, reinforced concrete and other composite materials. Abrasive blades can also be used for concrete, asphalt, stone masonry, and other materials.
When operating the Husqvarna K760, you must take several safety precautions:
Personal Protective Equipment (PPE):
General Safety:
Yes, abrasive blades can be used for cutting asphalt with the Husqvarna K760.
For best results and performance, use HUSQVARNA two-stroke engine oil which is specially formulated for air-cooled two-stroke engines. If you have a K760 OilGuard model, use HUSQVARNA OilGuard two-stroke oil. Never use two-stroke oil intended for water-cooled engines (rated TCW) or oil intended for four-stroke engines. The mixing ratio is 1:50 (2%) with HUSQVARNA two-stroke oil or equivalent, or 1:33 (3%) with oils class JASO FB or ISO EGB.
The air filter only needs to be checked if the engine drops in power. To clean it, loosen the screws and remove the air filter cover. Then, check the air filter and replace it if necessary. The air filter must not be cleaned or blown clean with compressed air, as this will damage it.
To prevent overheating:
If your Husqvarna K760 won't idle properly, you should first check the spark plug. If the machine runs poorly at idle speed, clean the spark plug and check that the electrode gap is 0.5 mm. Replace the spark plug if necessary. If the issue persists, you may need to adjust the idle speed using the T screw. If the idle setting cannot be adjusted so the blades are stationary, contact your dealer/service workshop.
The maximum cutting depth for the Husqvarna K760 depends on the blade size:
The fuel filter cannot be cleaned and must be replaced with a new filter when it is clogged. It should be changed at least once per year.
If your Husqvarna K760 runs rough or sputters, you should first check the spark plug. If the machine is low on power or runs poorly, clean the spark plug and check that the electrode gap is 0.5 mm. Replace it if necessary. Ensure the spark plug cap and ignition lead are undamaged. Other factors that can cause operating problems include an incorrect fuel mixture (too much or incorrect type of oil) or a dirty air filter.
The carburetor is equipped with fixed needles to ensure the machine receives the correct mixture of fuel and air. If the engine lacks power or accelerates poorly, you should first check the air filter and replace it if necessary. If this does not help, contact an authorized service workshop. The manual also mentions that carburetor adjustment may be necessary when changing the type of fuel.
Routine maintenance should be performed according to the maintenance schedule, which includes daily, weekly, and monthly intervals. The intervals are calculated based on daily use and may differ depending on usage rate.

To replace the pull cord:
To troubleshoot a faulty kill switch, you should start the engine and make sure it stops when you move the stop switch to the stop setting. If it doesn't stop, the switch may be faulty.
To adjust the idle speed, first start the engine and check the idling setting. The cutting blade should be stationary while the engine is idling. Use the T screw to adjust the idle speed. Turn the screw clockwise until the blade starts to rotate, then turn it anti-clockwise until the blade stops rotating. If the idle setting cannot be adjusted so the blades are stationary, contact your dealer/service workshop for repair.
To check and adjust the belt tension:
The correct spark plug gap for the Husqvarna K760 is 0.5 mm.
The guard for the cutting equipment should be adjusted so that the rear section is flush with the work piece. This helps collect spatter and sparks and direct them away from the user. The blade guard is friction locked. You can press the ends of the guard against the work piece or adjust the guard with the adjustment handle. The guard must always be fitted to the machine.
The arbor bushings are used to fit the machine to the center hole in the cutting blade. The machine is supplied with either a bushing that can be flipped over to fit blades with either 20 mm or 1" (25.4 mm) center holes, or with a fixed 20 mm bushing. A decal on the blade guard indicates which bushing has been factory fitted together with the appropriate blade specification. You must use only bushings supplied by Husqvarna.
The year of manufacture is clearly stated in plain text on the rating plate with the subsequent serial number.
The fuel tank capacity for the Husqvarna K760 is 0.9 litres.
To troubleshoot a sticky throttle trigger, you should check that the throttle trigger and throttle lockout move freely and that the return springs work properly. If the cutting blade rotates when the throttle is in the idle position, you should check the carburetor's idle adjustment.
To remove the air filter cover, you need to loosen the screws that hold it in place.
