" • AUTOMOTIVE OIL- Does not have proper additives for 2-cycle engines and can cause damage. • GASOLINECONTAINING High Test, Premium Methanol) 2. FUEL MIXTURE • Your tool is powered by a two-cycle engine which requires a fuel mixture of regular unleaded • gasoline and a high quality engine oil specially •made far 2-cycle, air cooled engines. The internal design of the 2-cycle engine requires lubrication of moving parts. Lubrication is provided when the recommended mixture of gasoline and oil is used. Gasoline must be clean and not over two months old. Gasoline will chemically break down and form compounds that cause hard starting and damage in 2-cycle engines. • The correct measure of gasoline to oil is very important. Too much oil in the mixture will fou! the spark plug.

CUTTING I IlllIIIII III II METHODS • The tip of the line does the cutting. Allow the line to trim at its own pace. You will achieve better results by .... not eroding the line into the cutting area. The right and wrong way are shown in Figure/3. • The line will easily remove grass and weeds from around walls, fences, trees and flower beds, but it also can cut the tender bark of trees or shrubs and scar fenceA To help avoid damage to vegetationor trees with tender bark, shorten line to 4-5 inches and use tess than full throttle. Always wear eye protection. Never lean over the trimmet head. Rocksor debriscan ricochet orbethrmm into eyes and face and cause blindness or other serious injury. 1. TRIMMING ,-.

Do not force the trimmer line into the workarea. • The line will wear faster and willneedto be advanced • more ti_uenfly whenyou are cutting against rocks, bricks, concrete, metal fences, etc., than when cutring against trees or wooden fences. 2. SCALPING -- Figure 15 •The scalping technique removes unwanted vegetation. Hold the tap button about 3 inches above the ground and tilt the trimmer head at an angle° Allow the tip of the line to strike the ground around trees, posts, monuments, etc. This technique increases line wear. • For trimmingor scalping, use less than full throttle to increase line life and decrease head wear. -- during light duty cutting. --next to rocks, bricks, concrete, metal fences, etc.. e-Formowingorsweeping, clean job. _ use full throttle for a good 3.
