• When working in a dusty area, clean air cleaner element twice a day. Dirty air
cleaner element results in poor starting, poor performance, or short life.
• When a cutting blade is broken, replace it and the other blade with a new pair. A
broken blade causes excessive vibration, which damages machine.
• When something is tangled to cutting blade, stop engine immediately and
remove the tangled object. Such object causes excessive vibration, which
damages machine.
• Always clean cutting blades and cutting blade stay after every use ( see page
75). Remained foreign object may solidified or corrode and make cutting blades
hard to remove.
• In case cut grass, dust, or foreign object enters between cutting blade pin and
slot, making it difficult to remove cutting blade, use a flathead screw driver or
similar tool to remove such object first.
• Use [L] mode when mowing. Mowing in [H] mode puts excessive strain on
mowing mechanism and may damage it.
• Always stay on machine when mowing.
• Make sure air intake for cooling is not clogged or blocked. If it is clogged or
blocked, it causes overheating, resulting in damages to machine.
