Read this before you order anything. These figures are transcribed automatically from manufacturer manuals and can be wrong. Nothing here is a fitment guarantee or professional advice.
Provided free, as is, with no warranty and no liability accepted — you use it at your own risk and on your own responsibility. Check every number against the plate on your own machine before you buy or fit a part.
Reference data — no warranty, no fitment guarantee, used at your own risk. Disclaimer
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.
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.
