What these parts do

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

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

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.
