Scraper blade adjustment
1. Tilt the snowblower forward
to provide access the
underside of the scraper
blade.
2. Loosen (don’t remove) the
three flange nuts on the
scraper blade.
3. Move the scraper blade
down slightly. Tighten the
self-locking nuts and
recheck the clearance.
Repeat the procedure as
needed to get the
necessary clearance. If
you cannot set the ground clearance within 1/8 ~ 1/16 inch,
replace the scraper blade.
Scraper blade replacement
A new scraper blade can be purchased from a servicing Honda
dealer. See page 16 for scraper blade and hardware part numbers.
1. Turn the engine switch and fuel valve to the OFF position (page 4)
and disconnect the spark plug cap so the engine cannot be
accidentally started.
2. Tilt the snowblower forward to provide access the underside of the
scraper blade.
3. Remove the three flange nuts, flat washers, and the scraper blade.
4. Install the new scraper blade, reusing the bolts, washers, and nuts.
5. Adjust the scraper blade. See "Scraper blade adjustment" above.
REFUELING
Honda recommends using a No-Spill® gas can, which meets the
demanding requirements of the California Air Resources Board
(page 17).
This engine is certified to operate on unleaded gasoline with a pump
octane rating of 86 or higher.
Refuel in a well-ventilated area with the engine stopped. If the engine
has been running, allow it to cool first. Never refuel the engine inside a
building where gasoline fumes may reach flames or sparks.
You may use regular unleaded gasoline 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.
Never use stale or contaminated gasoline or an oil/gasoline mixture.
Avoid getting dirt or water in the fuel tank.
To refuel, remove the fuel tank cap, and fill the tank with gasoline to
the shoulder of the filler neck. Refuel carefully to avoid spilling fuel. Do
not overfill.
After refueling, tighten the fuel tank cap securely.
Move the snowthrower at least 10 feet (3 meters) away from the
fueling source and site before starting the engine.
NOTICE
Fuel can damage paint and plastic. Be careful not to spill fuel when
filling your fuel tank. Damage caused by spilled fuel is not covered by
the DISTRIBUTOR’S LIMITED WARRANTY (page 18).
TRANSPORTING
BEFORE LOADING
If the engine has been running, allow it to cool for at least 15 minutes
before loading the snowthrower on the transport vehicle. A hot engine
and exhaust system can burn you and can ignite some materials.
Turn the fuel valve to OFF. This will prevent carburetor flooding and
reduce the possibility of fuel leakage.
Avoid removing any parts from the snowblower before transport,
unless you are mechanically proficient, have the right tools, and follow
the procedures in the HS520 Shop Manual.
LOADING AND UNLOADING
If a suitable loading ramp is not available, two people should lift the
snowthrower on and off the transport vehicle while holding the
snowthrower level.
Position the snowthrower so both wheels and the auger box are on
the bed of the transport vehicle. Tie the snowthrower down with rope
or straps, and block the wheels. Keep the tie-down rope or straps
away from the auger drive clutch lever and cable.
