This unit is shipped with a 20W50 engine lubricant to assist in the break-in period. For best operating performance, continuing to use 20W50 engine lubricant is recommended, however, SAE 30, 10W30, or 10W40 are all acceptable lubricants to use in this product. Always use a 4-stroke engine lubricant that meets or exceeds the requirements for API service classification SJ. Check lubricant level before each use.NOTE: Non-detergent or 2-stroke engine lubricants will damage the engine and should not be used.To add engine lubricant: Remove the cap and seal from lubricant bottle pro-vided. Unscrew the oil cap/dipstick and remove.  Using funnel provided, add entire bottle of engine lubricant through oil fill hole. Reinstall the oil cap/dipstick and secure. To check engine lubricant level: Set unit on a flat surface. Wipe dipstick clean and re-seat in hole; do not rethread. Remove dipstick again and check lubricant level. Lubricant level should fall within the hatched area on the dipstick. If level is low, add engine lubricant until the fluid level rises to the upper portion of the hatched area on the dipstick. Replace and secure the oil cap/dipstick.CAUTION:Do not overfill. Overfilling the crankcase may cause excessive smoke, oil loss, and engine damage.OPERATING THE TRIMMERSee Figure 9.WARNING:Engine housing may become hot during trimmer opera-tion. 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 9 with all body parts clear of engine housing. Extended contact with the engine housing may 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.Cut tall grass from the top down. This will prevent grass from wrapping around the shaft housing and string head which could cause damage from overheating. If grass becomes wrapped around the string head, STOP THE ENGINE, dis-connect the spark plug wire, and remove the grass. WARNING:Always hold the string trimmer away from the body keep-ing 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. 

10 — EnglishOPERATIONTO ADVANCE THE CUTTING LINE (REEL EASY STRING HEAD)Line advance is controlled by tapping the string head on grass while running engine at full throttle. Run engine at full throttle. Tap the knob on ground to advance line. The line advances each time the knob is tapped. Do not hold the knob on the ground.NOTE: The line trimming cut-off blade on the grass deflector will cut the line to the correct length.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 and manually advance the line.To advance the cutting line manually:Stop the engine and disconnect the spark plug wire. Push the knob in while pulling on line(s) to manually advance the line.NOTE: Dual Spool™ Fixed Line Adaptor line cannot be ad-vanced.

Store idle unit indoors in a dry, well-ventilated area that is inaccessible to children. Keep away from corrosive agents such as garden chemicals and de-icing salts. When storing the product vertically, do so with the engine up to avoid hydraulically locking the engine due to oil entering the combustion chamber. NOTE: If the engine/starter rope becomes locked after storage, place the unit flat on the ground in the upright position to allow the engine oil to slowly migrate back into the engine’s oil reservoir. Abide by all ISO and local regulations for the safe storage and handling of gasoline. When storing 1 month or longer: Drain all fuel from tank into a container approved for gasoline. Run engine until it stops.HIGH ALTITUDE ENGINE OPERATIONPlease have an authorized service center adjust this engine if it is to be run above 2000 feet. Failure to do so may result in poor engine performance, spark plug fouling, hard start-ing, and increased emissions. Carburetor adjustment by an authorized service center will improve performance and allow that this engine meets EPA (Environmental Protection Agency) and California ARB (Air Resources Board) emis-sion standards. An engine adjusted for high altitudes can not be run at 2000 feet or lower. In doing so, the engine will overheat and cause serious engine damage. Please have an authorized service center restore high altitude modified engines to the original factory specification before operating below 2000 feet.
