STARTING
CAUTION:
Some engines may be equipped with
Oil Gard R .
The
Oil Gard R
is intended to warn the operator that the engine is low on oil. Always check oil
level before starting. Engine damage may occur if the oil level is not properly
maintained and will void warranty coverage. If the engine will not start, has
stopped running and/or a light flickers in the stop switch, add oil (see oil
procedure Fig. 2).
