Use the manufacturer’s replacement string for best perfor- mance. 1. Stop the engine and disconnect the sparking plug wire. Hold the string head and unscrew the spool retainer. Turn clockwise. 2. Remove the empty spool from the string head. Keep the spring attached to the spool. 3. To install the new spool, make sure the two strings are captured in the slots opposite each other on the new spool. Make sure the ends of each string are extended approximately 152 mm (6 in) beyond each slot. 4. Thread the strings into the eyelets in the string head. Carefully push the spool into the string head (gently pull the strings to the outside if necessary). When the spool is positioned in the string head, grasp the strings and pull sharply to release them from the slots in the spool. 5. Push down and turn the spool anticlockwise until it no longer turns. Hold the spool down and rotate clockwise a small amount. Release the spool. The spool should be locked down in the string head. If not, hold down and rotate until locked. 6. Make sure the string head and the spool retainer are installed on the drive shaft by turning the retainer anticlockwise to tighten. 7. Pull the strings again to rotate the spool into cutting position. Push the spool retainer down while pulling on string(s) to manually advance the string and to check for proper assembly of the string head. 12 MAINTENANCE STRING REPLACEMENT See Figures 12, 13, 14 and 15. 1 Stop the engine and disconnect the sparking plug wire. Hold the string head and unscrew the spool retainer. Turn anticlockwise. 2 Remove the spool from the string head. NOTE: Keep the spring attached to the spool. Remove any old string remaining on the spool. 3 Cut two pieces of string, each being approximately 2.7 m (9 ft) long. 4 Insert the first string into the anchor hole in the upper part of the spool. Wind the first string round the upper part of the spool anticlockwise, as shown by the arrows on the spool. Place string in the slot on upper spool flange, leaving about 152 mm (6 in) extended beyond the slot. Do not overfill. After winding the string, there should be at least 6 mm (1/4 in) between the wound string and the outside edge of the spool. 5 Repeat above step with second string, using the bottom part of spool. Do not overfill. 6 Replace the spool and the spool retainer. Refer to “Spool Replacement“ earlier in this manual. CLEANING THE EXHAUST PORT AND SILENCER Depending on the type of fuel used, the type and amount of oil used, and/or your operating conditions, the exhaust port and silencer may become blocked with carbon deposits. If you notice a power loss with your petrol-powered tool, a qualified service technician will need to remove these deposits to restore performance. SPARK ARRESTER The spark arrester must be cleaned or replaced every 25 hours or yearly to ensure proper performance of your product. Spark arresters may be in different locations depending on the model purchased. Please contact your nearest service dealer for the location of the spark arrester for your model. Cleaning Instructions: ¦ ¦¦¦¦¦Remove the spark arrester from the silencer. ¦ ¦¦¦¦¦If your spark arrester is made of fibreglass, discard and replace. ¦ ¦¦¦¦¦If your spark arrester is made of metal, follow these cleaning instructions: 1. Spray the spark arrester with a quality carbon cleaner. 2. Gently clean using a wire brush. 3. Install the new or cleaned spark arrester and reassemble completely before use. 13 FIRST STRING Fig. 12 SPOOL ANCHOR HOLE SECOND STRING ARROWS ON SPOOL Fig. 14 Fig. 15 SPRING Fig. 13 FIRST STRING SLOT SLOT ARROWS ON SPOOL 14 The fuel cap contains a non-serviceable filter and a check valve. A clogged fuel filter will cause poor engine performance. If performance improves when the fuel cap is loosened, the check valve may be faulty or the filter clogged. Replace fuel cap if required. SPARKING PLUG This engine uses a Champion RCJ-6Y with 0.63mm (0.025 in) electrode gap. Use an exact replacement and replace annually. STORAGE (1 MONTH OR LONGER) 1. Drain all fuel from tank into a container approved for petrol. Run engine until it stops. 2. Clean all foreign material from the trimmer. Store it in a well-ventilated place that is inaccessible to children. Keep away from corrosive agents such as garden chemicals and de-icing salts. 3. Abide by all Federal and local regulations for the safe storage and handling of petrol. Excess fuel should be used up in other 2-cycle engine powered equipment. REPLACING AND CLEANING AIR FILTER See Figures 16 and 17. For proper performance and long life, keep air filter clean. 1. Remove the air filter cover by pushing down on the latch with your thumb while gently pulling on the cover. 2. Remove the filter and clean it in warm soapy water. Rinse and let dry completely. For best performance, replace annually. 3. Install the filter, align tabs, push in, and make sure the latches are locked into place. WARNING: A leaking fuel cap is a fire hazard and must be replaced...
