OPERATION ADDING/CHECKING ENGINE LUBRICANT See Figure 4. Engine lubricant has a major influence on engine performance and service life. 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 motor lubricant that meets or exceeds the requirements for API service classification SJ. Check lubricant level before each use. NOTE: Non-detergent or 4-stroke engine lubricants will damage the engine and should not be used. To add engine lubricant:  Remove the cap and seal from lubricant bottle provided.  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 POWER HEAD See Figure 5. WARNING: Engine housing 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 5 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.
