engine and check the blade for cracks or other damage. Replace a damaged blade IMMEDIATELY!

WARNING!

nNever repair a damaged blade by welding, staightening, or by modifying its shape. An altered blade may break during opera- tion, resulting in serious personal injury.

nDO NOT use 2-tooth or NON- Shindaiwa approved 4-tooth cutting blades on Shindaiwa trim- mers or brushcutters.

nBlades are not interchangeable between Shindaiwa edgers and trimmer/brushcutter models.

Operating any unit with a blade or attachment not approved for that unit can be hazardous and may cause serious injury.

(For electro magnetic compliance (EMC) use an NGK BMR6A resistor plug.)

See Figure 27.

CAUTION!

Before removing the spark plug, clean the area around the plug

to prevent dirt and debris from getting into the internal engine parts.
