To do a check of the cutting cover The cutting cover decreases vibrations in the product and decreases the risk of injury from the blade. • Examine the cutting cover to make sure that there are no damages such as cracks. To do a check of the blade brake control and the start inhibitor The blade brake control stops the blade only and not the engine. When the blade brake control is released, the blade stops. 1. Start the engine. 2. Push the blade brake control in the direction of the handlebar. The start inhibitor stops the movement. 3. Push the start inhibitor out. 4. Push the blade brake control in the direction of the handlebar. The blade starts to rotate. 5. Release the blade brake control. If the blade does not stop in 3 seconds, let an approved Husqvarna service agent adjust the blade brake. (Fig. 29) 6. Make sure that the start inhibitor goes back to its initial position. Muffler The muffler keeps the noise levels to a minimum and sends the exhaust fumes away from the operator. Do not use the product if the muffler is missing or defective. A defective muffler increases the noise level and the risk of fire. WARNING: The muffler becomes very hot during and after use and when the engine operates at idle speed. Be careful near flammable materials and/or fumes to prevent fire. To do a check of the muffler • Examine the muffler regularly to make sure that it is attached correctly and not damaged. 1500 - 005 - 23.09.2020 11
