Engine Oil Level; Petrol - Honda HRX537HYEA Owner's Manual

Lawn
Check the length and condition of the grass, so that you will know
what cutting height and mowing speed to use.
Avoid mowing wet grass. Not only will wet grass clog your mower
deck and collect in clumps on the lawn, it also gives poor traction,
increasing your risk of losing your footing.
CHECK YOUR MOWER
Blades
1. Move the throttle
lever to the STOP
position (page 4).
2. Move the fuel valve
to the OFF position
(page 4).
3. Disconnect the spark
plug cap from the
spark plug (page 14).
4. Tilt the mower to the
right so the fuel cap
is up. This will help
prevent fuel leakage,
motor oil seeping into the air filter, and hard starting.
5. Inspect the blades [1] for damage, cracks, and excessive wear,
rust, or corrosion.

WARNING
A worn, cracked, or damaged blade can break, and
pieces of the damaged blade can become dangerous
projectiles.
Thrown objects can cause serious injury.
Inspect the blade regularly, and do not operate the
mower with a worn or damaged blade.
A dull blade can be sharpened, but a blade that is worn out, bent,
cracked, or otherwise damaged must be replaced. A worn or
damaged blade can break, causing blade pieces to be thrown from
the mower.
When a blade needs sharpening or replacement, take the lawn
mower to an authorized Honda dealer. Or, if you have a torque
wrench, you can remove and install the blades yourself.
Check that the blade bolts [2] are tight (page 16).

Engine Oil Level

Check the engine oil level with the engine stopped and the mower on
a level surface.
Use 4-stroke motor oil that meets or exceeds the requirements for API
service classification SJ or later. Always check the API service label
on the oil container to be sure it includes the letters SJ or later.
SAE 10W-30 is recommended
for general use. Other
viscosities shown in the chart
may be used when the average
temperature in your area is
within the indicated range.
NOTICE
• Running the engine with a low oil level can cause engine damage.
• Using nondetergent oil can shorten the engine's service life, and
using 2-stroke oil can damage the engine.
1. Remove the oil filler
cap/dipstick [1], and wipe the
dipstick clean.
2. Insert the dipstick into the filler
neck. Do not screw it down.
Remove the dipstick and check
the oil level.
3. If the oil level is near the low
level mark [3], add the
recommended oil to bring the
level up to the high limit mark
[2]. Do not overfill.
4. Install and tighten the filler
cap/dipstick [1] securely.

Petrol

This engine is certified to operate on unleaded petrol with a research
octane rating of 91 or higher.
Refuel in a well-ventilated area before starting the engine. If the
engine has been running, allow it to cool. Never refuel the mower
inside a building where petrol fumes may reach flames or sparks.
You may use regular unleaded petrol containing no more than 10%
ethanol (E10) or 5% methanol by volume. In addition, methanol must
contain cosolvents and corrosion inhibitors. Use of fuels with content
of ethanol or methanol greater than shown above may cause starting
and/or performance problems. It may also damage metal, rubber, and
plastic parts of the fuel system. Engine damage or performance
problems that result from using a fuel with percentages of ethanol or
methanol greater than shown above are not covered by warranty.
If your equipment will be used on an infrequent or intermittent basis,
please refer to the fuel section of the STORAGE chapter (page 17) for
additional information regarding fuel deterioration.
B
Petrol is highly flammable and explosive.
You can be burned or seriously injured when handling fuel.
• Stop the engine and keep heat, sparks, and flame away.
• Handle fuel only outdoors.
• Wipe up spills immediately.
Never use stale or contaminated petrol or an oil/petrol mixture. Avoid
getting dirt or water in the fuel tank.
