OPERATION OPERATING THE TRIMMER See Figure 6. WARNING: Engine housing on gas power heads may become hot during trimmer operation. Do not rest or place your arm, hand, or any body part against the engine housing during trimmer operation. Only hold the trimmer as shown in Figure 6 with all body parts clear of engine housing. Extended contact with the engine housing can result in burns or other injuries. WARNING: Always position the unit on the operator's right side. The use of the unit on the operator's left side will expose the user to hot surfaces and can result in possible burn injury. WARNING: To avoid burns from hot surfaces, never operate unit with the bottom of the engine above waist level. Hold the trimmer with your right hand on the rear handle and your left hand on the front handle. Keep a firm grip with both hands while in operation. Trimmer should be held at a comfortable position with the rear handle about hip height. Always operate trimmer at full throttle for gas power heads or with the switch trigger fully pressed for cordless and electric power heads. Cut tall grass from the top down. This will prevent grass from wrapping around the shaft housing and string head which may cause damage from overheating. If grass becomes wrapped around the string head, STOP THE ENGINE or MOTOR, disconnect the spark plug wire for gas power heads, remove the battery pack for cordless power heads, or disconnect the plug from the power source for electric power heads, and remove the grass. Prolonged cutting at partial throttle will result in lubricant dripping from the muffler. WARNING: Always hold the string trimmer away from the body keeping clearance between the body and the product. Any contact with the housing or string trimmer cutting head can result in burns and/or other serious personal injury. CUTTING TIPS See Figures 6 - 7.  Avoid hot surfaces by always keeping the tool away from your body. (Proper operating position shown in figure 6.)  Keep the trimmer tilted toward the area being cut; this is the best cutting area.  The trimmer cuts when passing the unit from left to right. This will avoid throwing debris at the operator. Avoid cutting in the dangerous area shown in figure 7.  Use the tip of line to do the cutting; do not force string head into uncut grass.  Wire and picket fences cause extra line wear and breakage. Stone and brick walls, curbs, and wood may wear line rapidly.  Avoid trees and shrubs. Tree bark, wood moldings, siding, and fence posts can easily be damaged by the line. ADVANCING LINE USING THE REEL-EASY™ TAP ADVANCE SYSTEM Line advance is controlled by tapping the string head's spool retainer on grass while running engine at full throttle for gas power heads or with the switch trigger fully pressed for cordless and electric power heads.  Run engine at full throttle for gas power heads or with the switch trigger fully pressed for cordless and electric power heads.  Tap string head on ground to advance line. Line ­advances each time the head is tapped.  Several taps may be required until line strikes the cut off blade.  Resume trimming. NOTE: If the line is worn too short you may not be able to advance the line by tapping it on the ground. If so, STOP THE ENGINE or MOTOR, disconnect the spark plug wire for gas power heads, remove the battery pack for cordless power heads, or disconnect the plug from the power source for electric power heads, and manually advance the line. ADVANCING THE LINE MANUALLY Stop the unit and disconnect the spark plug wire for gas power heads, remove the battery pack for cordless power heads, or disconnect from power supply for electric power heads. Push the spool retainer down while pulling on line(s) to manually advance the line. 7 - English
