Fuel Containing Alcohol; Adjusting Cutting Height; Checking The Air Cleaner - Honda HRX476C Owner's Manual

FUEL CONTAINING ALCOHOL

If you intend to use fuel with alcohol, ensure that its octane number
is at least as high as that recommended by Honda (86). There are
two types of fuel/alcohol mixtures: one contains ethanol and the
other methanol.
Do not use mixtures containing more than 10 % ethanol, or fuel
containing methanol (methyl or wood alcohol), which do not contain
cosolvents, or corrosion inhibitors for methanol.
In the case of a mixture containing methanol with addition of
cosolvents and corrosion inhibitors, limit the proportion to 5 % of
methanol.
NOTE: The guarantee does not cover damage caused to the fuel
system or engine performance problems resulting from the use of
fuel containing alcohol. Honda does not give its approval to the use
of fuels containing methyl alcohol since their suitability is not yet
proven.

CHECKING THE AIR CLEANER

CAUTION:
• Never run the engine without the air cleaner fitted since this could
cause premature engine wear.
To check the condition of the air cleaner:
1. Press the latch tabs [1]
on the top of the air
cleaner cover and
remove the cover [2].
2. Check the cleanliness
of filter element [3].
If the element is dirty,
follow the cleaning
procedure (see
Maintenance chapter).
3. Reinstall the filter [3]
and air cleaner
cover [2].
CHECKING BLADE
CONDITION
CAUTION:
• Do not tilt the mower with the
carburetor facing down; this will
make the mower difficult to start
later, due to engine oil
contaminating the air cleaner.
To check blade condition:
1. Stop the engine.
2. Pull off the spark plug cap.
3. Tilt the mower to the right so the
fuel cap is up [4].
• Check if the blade is showing
signs of wear. For your
information, it is necessary to replace the blade when the
recesses join together, or when a crack appears.

EXCESSIVELY WORN
Never operate the mower with a worn, damaged, split or dented
blade. A piece of blade which breaks off and is thrown
outwards can cause serious bodily injuries.
NOTE: Blade wear is increased when the mower is used on sandy
soils. Inspect the blade more often when the mower is used in these
conditions.

ADJUSTING CUTTING HEIGHT

To change the cutting height:
1. Stop the engine.
2. Keep the unlocking knob [5] pressed and raise or lower the

The cutting height settings are approximate values, the actual
height of the cut grass varies with the lawn and ground condition. To
choose the cutting height, check how the lawn looks after mowing a
