Troubleshooting - Honda HRX537VYE Owner's Manual

Engine Oil
Change the engine oil (page 13).
Engine Cylinder
If the mower is to be stored for
more than 3 months, remove
the spark plug (page 14). Pour
5 ~ 10 cc of clean engine oil
into the cylinder [1]. Pull the
starter rope several times to
distribute the oil in the cylinder.
Reinstall the spark plug.
Pull the starter rope slowly
until resistance is felt, then
return the starter grip gently.
This will close the valves so
moisture cannot enter the
engine cylinder.
PLACING IN STORAGE
Since your mower will be stored with petrol in the fuel tank and
carburetor, it is important to reduce the hazard of petrol vapor ignition.
Select a well-ventilated storage area away from any appliance that
operates with a flame, such as a furnace, water heater, or clothes
dryer. Also avoid any area with a spark-producing electric motor, or
where power tools are operated.
If possible, avoid storage areas with high humidity, because that
promotes rust and corrosion.
Place the mower with its wheels on a level surface. Tilting can cause
fuel or oil leakage.
The handlebar can be folded for compact storage (page 17).
With the engine and exhaust system cool, cover the mower to keep
out dust. A hot engine and exhaust system can ignite or melt some
materials. Do not use sheet plastic as a dust cover. A nonporous
cover will trap moisture around the mower, promoting rust and
corrosion.
REMOVING FROM STORAGE
Check your mower as described in PRE-OPERATION CHECKS
(page 6).
If the cylinder was coated with oil during storage preparation, the
engine will smoke briefly at startup. This is normal.
