SPARK PLUG
• Starting failure and mis-firing are often caused by a
fouled spark plug. Clean the spark plug and check that
the plug gap is in the correct range. For a replacement
plug, use the correct type specified by Husqvarna.
0.025 inch
0.6 ~ 0.7 mm
• REPLACEMENT PLUG IS NGK CMR7H OR CHAMPION
RZ7C.
IMPORTANT
• Note that using any spark plug other than those
designated may result in the engine failing to operate
properly or in the engine becoming overheated and
damaged.
• To install the spark plug, first turn the plug until it is
finger tight, then tighten it a quarter turn more with a
socket wrench.
