Husqvarna HU625HWT Operation Manual - Page 8

MAINTENANCE GENERAL RECOMMENDATIONS The warranty on this trimmer does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, operator must maintain trimmer as instructed in this manual. Some adjustments will need to be made periodically to properly maintain your unit. All adjustments in the Service and Adjustments section of this manual should be checked at least once each season. • Once a year, replace the spark plug and replace air filter element. A new spark plug and clean/new air filter element assure proper air-fuel mixture and help your engine run better and last longer. • Follow the maintenance schedule in this manual. BEFORE EACH USE 1. Check engine oil level. 2. Check for loose fasteners. 3. Clean under engine cover. LUBRICATION To prolong the useful life of your trimmer, change engine oil as recommended in this section of Operator's Manual. IMPORTANT: Do not oil or grease plastic wheel bearings. Viscous lubricants will attract dust and dirt that will shorten the life of the self- lubricating bearings. If you feel they must be lubricated, use only a dry, powdered graphite type lubricant sparingly. TRIMMER Always observe safety rules when performing any maintenance. 20" MODELS Chassis cover TIRES • Keep tires free of gasoline, oil, or insect control chemicals which can harm rubber. • Avoid stumps, stones, deep ruts, sharp objects and other hazards that may cause tire damage. TRIMMER LINE For best results, replace trimmer lines when they have worn to half their original length. Debris shield End of mark spooled line Wrap line around New trimmer line 20" models use .130 inch diameter trimmer line. Cut new trimmer line length to 16-3/4 inches. 22" models use .155 inch diameter trimmer line. Cut new trimmer line length to 18-3/4 inches. After new line is installed on trimmer head, check all lines so they do not vary more then one (1) inch in length. This is important to make sure the trimmer head is balanced and will not vibrate abnormally. WARNING: Use only the specified trimmer line. Do not use other materials such as wire, string, rope, etc. Wire can break off during trimming and become a dangerous missile that can cause serious injury. TO CUT LINE TO PROPER LENGTH NOTE: Trimmer line pre-cut to proper length is available for this unit; see the Repair Parts section of this manual. If trimmer line is purchased in bulk, it must be cut to length before using. Use the built-in length guage as follows: 1. From front of trimmer, place the end of spooled trimmer line at the mark on the side of the debris shield as shown. 2. Wrap trimmer line around front of chassis cover to other side and cut at the mark (for your unit's width of cut). 22" MODELS Debris shield End of mark spooled line Chassis cover WRAP LINE AROUND New trimmer line 8 9
