Air Filter; Spark Plug - Honda HRC216HXA Owner's Manual

Engine Oil
Recommendations
Oil is a major factor affecting
performance and service life. Always
change the oil in accordance with the
MAINTENANCE SCHEDULE
(page 11).
Recommended oil for general use:
SAE 10W-30
Other viscosities shown in the chart
may be used when the average
temperature in your area is within the
recommended range.
The SAE oil viscosity and service classification are in the API label on
the oil container. Honda recommends API service category SJ or later
oil.

Air Filter

Clean the air filter after the first 25 hours of use. Thereafter, clean the
filter every 6 months or 50 hours of use. Clean the filter more often
when used in dusty areas. Replace the filter every 2 years or 150
hours of use.
A properly maintained air filter will help prevent dirt from entering your
engine. Dirt entering the carburetor can be drawn into small passages
in the carburetor and cause premature engine wear. These small
passages can become blocked, causing starting or running problems.
NOTICE
Operating the engine without an air filter, with a damaged air filter, or
with an improperly installed air filter cover will allow dirt to enter the
engine, causing rapid engine wear. This type of damage is not
covered by the DISTRIBUTOR'S LIMITED WARRANTY
We recommend the use of a Honda Genuine air filter to ensure it
seals and performs as designed. Using a non-Honda air filter can
result in dirt bypassing the filter, causing damage to the engine or fuel
system.
1. Remove the wing nuts from the
air cleaner cover.
2. Remove the air filter and
separate the filter elements.
3. Inspect the elements for holes,
tears, or other damage, and
replace them if they are
damaged.
4. Clean the elements:
Paper: Tap the element several
times on a hard surface to
remove dirt, or blow compressed
air not exceeding 30 psi [207
kPa] through the filter from the
inside. Never try to brush off dirt;
brushing will force dirt into the
fibers.
Foam: Clean in warm soapy
water and rinse or clean in
non-flammable solvent and allow
to dry. Apply oil to the clean filter
and squeeze out all excess oil.

NOTICE
Excess oil will restrict air flow through the foam element and may
transfer to the paper element, soaking and clogging it.
5. Use a moist rag to wipe dirt from the inside of the air cleaner
housing and cover. Be careful to prevent dirt from entering the air
duct that leads to the carburetor.
6. Place the foam air filter element over the paper element and
reinstall the assembled air filter.
7. Install the air cleaner cover and tighten the cover wing nuts
securely.

Spark Plug

Replace the spark plug every 2 years or after 150 hours of use.
Recommended Spark Plug: NGK - BPR5ES
NOTICE
An incorrect spark plug can cause engine damage.
For good performance, the spark plug must be properly gapped and
free of deposits.
1. Allow the engine to cool,
disconnect the spark plug
cap, and remove any dirt
from around the spark
plug area.
2. Remove the spark plug
with a 13/16 in (21 mm)
spark plug wrench.
3. Inspect the spark plug.
Replace it if the
electrodes are worn, or if
the insulator is cracked or
chipped.
4. Measure the spark plug
electrode gap with a
suitable gauge.
Gap: 0.028 ~ 0.031 in
(0.7 ~ 0.8 mm).
Correct the gap, if
necessary, by carefully
bending the side
electrode.
5. Install the spark plug
carefully, by hand, to
avoid cross-threading.
6. After the spark plug
seats, tighten with a
13/16 in (21 mm) spark plug wrench to compress the washer.
If reinstalling the old spark plug, tighten 1/8 to 1/4 turn after the
spark plug seats.
If installing a new spark plug, tighten 1/2 turn after the spark plug
seats.
Spark plug torque: 14 ft-lb (20 N·m)
NOTICE
A loose spark plug can overheat and damage the engine.
Overtightening the spark plug can damage the threads in the
cylinder head.
7. Install the spark plug cap on the spark plug.
