WARNING
This machine does NOT have the engine oil when it shipped out.
●
Make sure proper amount of oil is in there.
To always operate this machine in good condition, perform oil changes periodically.
●
When performing inspection, replacement, or lubrication of oiled parts, place the machine on a
●
flat, open surface. Switch on the engine and warm it up to confirm it is working properly. Then
switch off the engine, allow it to cool down and remove the spark plug cord.
After switching off, please wait at least 10 minutes for all parts to cool down sufficiently before you
touch the machine. After the engine has stopped, the body will be very hot and can cause burns
if touched. Furthermore, oil will still be in the engine and transmission so the quantity of oil
remaining will not be exactly displayed.
After changing the oil, please dispose of waste oil appropriately.
