Spark Arrester Service (if equipped)

Your lawn mower engine is not factory-equipped with a spark arrester.
In some areas it is illegal to operate an engine without a spark
arrester. Check local laws and regulations. In optional USDA
approved spark arrester is available from an authorized Honda
servicing dealer (see

page 19

for part numbers).

The spark arrester must be serviced every 100 hours to keep it
functioning as designed.

1. Allow the engine to cool and disconnect the spark plug cap.

2. Remove the three flange bolts and the heat shield. Remove the

setscrew and the spark arrester from the muffler.

3. Check for carbon deposits on the spark arrester and the exhaust

port. Use a brush to remove any carbon deposits from the screen.
Replace the screen if it is torn or damaged.

4. Installation is the reverse of removal. Tighten all hardware.

5. Reconnect the spark plug cap.

SMART DRIVE CABLE CHECK/ADJUSTMENT

Cable Check

With the engine off, set the
multi-position adjuster in the lowest
position.

Gradually push the Smart Drive
control down while pulling the
lawnmower backwards. The rear
wheels should lock up

before

the

Smart Drive paddles are straight
up-and-down.

Cable Adjustment

With the engine off, loosen the jam
nut one revolution.

Without pushing the Smart Drive
control, pull the lawn mower
backwards to check wheel
resistance.

If no wheel resistance exists, mark
the adjuster and TIGHTEN the
adjuster one turn at a time until the
wheels lock-up when pulling
rearward.

Turn the adjuster in the LOOSEN
direction 8 complete revolutions.

Tighten the jam nut to lock the
adjuster in place.

REFUELING

This engine is certified to operate on unleaded gasoline with a pump
octane rating of 86 or higher.

We recommend refueling after each use to minimize the air present in
the fuel tank.

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. In addition, ethanol is hygroscopic,
which means it attracts and retains water in 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
(more than 4 weeks before next use), refer to the

Fuel

section of the

STORAGE

chapter (

page 15

) for additional information regarding fuel

deterioration.

Never use stale or contaminated gasoline or an oil/gasoline mixture.
Avoid getting dirt or water in the fuel tank.
