Replacing The Spark Plugs - Toro 08703 Operator's Manual

Replacing the Air Filter

1. Release the latches securing the air cleaner cover to the
air cleaner body (Figure 27).

2. Remove the cover from the air cleaner body. Before
removing the filter, use low pressure air (40 psi, clean
and dry) to help remove large accumulations of debris
packed between outside of primary filter and the
canister.
Important: Avoid using high pressure air which
could force dirt through the filter into the intake
tract. This cleaning process prevents debris from
migrating into the intake when the primary filter
is removed.
3. Remove and replace the filter.
Inspect the new filter for shipping damage, checking
the sealing end of the filter and the body. Do not use
a damaged element. Insert the new filter by applying
pressure to the outer rim of the element to seat it in the
canister. Do not apply pressure to the flexible center
of the filter.
Note: Cleaning of the used element is not
recommended due to the possibility of damage to the
filter media.
4. Clean the dirt ejection port located in the removable
cover. Remove the rubber outlet valve from the cover,
clean the cavity and replace the outlet valve.
5. Install the cover orienting the rubber outlet valve in a
downward position - between approximately 5:00 to
7:00 when viewed from the end.
6. Secure the latches.

Replacing the Spark Plugs

Service Interval: Every 800 hours
Replace the spark plugs after every 800 operating hours or
yearly, whichever occurs first.
Type: Champion RC14YC (or equivalent)
Air Gap: 0.030 in. (0.76 mm)
Note: The spark plug usually lasts a long time; however, the
plug should be removed and checked whenever the engine
malfunctions.
1. Clean the area around the spark plugs so that foreign
matter cannot fall into the cylinder when the spark
plug is removed.
2. Pull the spark plug wires off of the spark plugs and
remove the plugs from the cylinder head.
3. Check the condition of the side electrode, center
electrode, and center electrode insulator to ensure that
there is no damage.
Important: A cracked, fouled, dirty, or otherwise
malfunctioning spark plug must be replaced. Do
not sand-blast, scrape, or clean the electrodes by
using a wire brush because grit may eventually
release from the plug and fall into the cylinder.
The result is usually a damaged engine.
4. Set the air gap between the center and side of the
electrodes at 0.030 in. (0.76 mm) (Figure 28). Install
the correctly gapped spark plug with gasket seal, and
tighten the plug to 200 in-lb (23 N-m). If a torque
wrench is not used, tighten the plug firmly.
