Husqvarna HU625HWT Operation Manual - Page 6

The operation of any trimmer can result in foreign objects being thrown into the eyes, which can result in severe eye damage. Always wear safety glasses or eye shields while operating your trimmer or performing any adjustments or repairs. We recommend standard safety glasses or a wide vision safety mask worn over spectacles. HOW TO USE YOUR TRIMMER ENGINE SPEED The engine speed is controlled by a throt- tle located on the side of the upper handle. FAST position is for starting and normal trimming. SLOW is for light trimming and fuel economy. STOP is for stopping the engine. STOP TO ADJUST TRIMMING HEIGHT CAUTION: Stop the engine and wait for all moving parts to stop. Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with plug. The height of cut can be set to six (6) different positions ranging from 1-1/2 inches to 3 inches. Recommended cutting height for the average yard is 2 inches. 1. To adjust trimming height, push in the locking plate tab and move trimmer head up or down to desired position. 2. Release tab and be sure head is locked into one of the six (6) height positions. TRIMMER HEAD DRIVE CONTROL Your trimmer is equipped with a trimmer head drive control bar which will require the operator to be positioned behind the trimmer handle to operate the trimmer. • To start trimmer head rotation, push the trimmer head control lever (1) forward and hold the trimmer head control bar down to the handle (2). • To stop trimmer head rotation, release the trimmer head control bar.

For type and grade of oil to use, see "ENGINE" in the Maintenance section of this manual. CAUTION: DO NOT overfill engine with oil, or it will smoke on startup. 1. Be sure trimmer is level and area around oil fill is clean. 2. Remove oil dipstick from oil fill spout. Make sure that rim of spout is clean. 3. You receive a container of oil with the unit. Slowly pour the entire container down the oil fill spout into the engine. NOTE: Initial oil fill requires only 18 oz. due to residual oil in engine from the manufacturers 100% quality testing. When 6 changing oil you may need 20 oz. • Turn trimmer on its side. Make sure air filter and carburetor are up. Clean the underside of your trimmer by scraping to remove build-up of grass and trash. • Clean engine often to keep trash from accumulating. A clogged engine runs hotter and shortens engine life. • Keep finished surfaces and wheels free of all gasoline, oil, etc. • We do not recommend using a garden hose to clean trimmer unless the electrical system, muffler, air filter and carburetor are covered to keep water out. Water in engine can result in shortened engine life. SERVICE AND ADJUSTMENTS CAUTION: Before performing any service and adjustments: 1. Stop engine. 2. Make sure the rotating lines and all moving parts have completely stopped. 3. Disconnect spark plug wire from spark plug and place where it cannot come in contact with plug.
