Safety devices on the product
WARNING: Read the warning instructions that follow before you use the product.

• Do not use a product with defective safety devices.
• Do a check of the safety devices regularly. If the safety devices are defective, speak to your Husqvarna service agent.

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 belt guard
The belt guard decreases the risk of injury and makes sure that a broken drive belt does not eject.

• Make sure that the belt guard does not have damages and that it is correctly attached. (Fig. 14)

Engine brake handle
The engine brake handle stops the engine. When the engine brake handle is released, the engine stops.
To do an inspection of the engine brake, start the engine and then release the engine brake handle. If the engine does not stop in 3 seconds, let an approved Husqvarna
service agent adjust the engine brake.
(Fig. 15)

To do a check of the vibration damping system
WARNING: Overexposure to vibration can cause circulatory damage or nerve damage to persons with decreased blood circulation. Get medical aid if you have symptoms of overexposure to vibration.
These symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin color or condition.
These symptoms usually show in the fingers, hands or wrists.

The vibration damping system decreases vibration in the handle during operation.
The steel tube in the handlebar and the cutting cover decrease vibration. KLIPPO LB 548SQe also has 4 vibration damping units attached to the handlebar.

• Examine the handlebar and the vibration damping units to make sure that there are no damages. (Fig. 16)

Blade support
The blade support decreases the risk that the engine shaft bends. If the blade hits an object, the blade moves against the blade support. The movement causes wear on the surface of the blade support. The wear shows that the protection of the engine shaft functions correctly.
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.

1. The power rating of the engine indicated is the average net output (at specified rpm) of a typical production engine for the engine model measured to SAE standard J1349/ISO1585. Mass production engines may differ from this value. Actual power output for the engine installed on the final product will depend on the operating
   speed, environmental conditions and other values.

2. If SAE-30 oil is used at temperature lower than +5 °C, there is a risk that it does not lubricate the engine sufficiently. This can cause engine damage. Refer to To replace the engine oil on page 15 for the correct oil for low temperatures.

3. Noise emissions in the environment measured as sound power (LWA) in conformity with EC directive 2000/14/EC.

4. Noise pressure level according to ISO 5395. Reported data for noise pressure level has a typical statistical dispersion (standard deviation) of 1.2 dB (A).

5. Vibration level according to ISO 5395. Reported data for vibration level has a typical statistical dispersion (standard deviation) of 0.2 m/s2.
