Transcribed from the manufacturer manual — not a fitment guarantee. Manufacturers supersede part numbers during a production run: check these against the plate on your own machine before ordering.

Note: some values below appear more than once in the manual without a clear label. This usually means the model changed across production years. Check your serial number plate before ordering.

What these parts do

Spark plug — Replace annually or every 100 operating hours. Cross-reference equivalents from other brands usually fit.

Spark plug gap — Set with a feeler gauge before installing. A wrong gap causes hard starting and rough running.

Engine oil — Grade depends on operating temperature, not on the machine. Several grades listed below are all correct — pick by season.

Air filter — Check every 25 hours, more often in dusty conditions. A clogged filter shows up as black smoke and power loss.

Belt — Belts are consumables. Length and width must match exactly — a belt that is half an inch off will throw or burn.

Blade — Sharpen or replace at the start of each season. Always balance a sharpened blade before refitting.
