Replacing Spark Plug; Storage - Toro 38542 Operator's Manual

Replacing Spark Plug

Use a Champion RJ–19LM spark plug or equivalent.
Set air gap at 0.030" (0.76 mm). Check spark plug
yearly or every 100 operating hours. If electrodes in
center of plug are dark or have deteriorated, install a
new plug.
1. Clean area around spark plug so foreign matter
cannot fall into cylinder when plug is removed.
2. Pull wire off spark plug (Fig. 31) and remove
plug from cylinder head.
IMPORTANT: A cracked, fouled or dirty
spark plug must be replaced. Do not sand
blast, scrape or clean electrodes because grit
may eventually release from the plug and fall
into the cylinder. The result will likely be
engine damage.
3. Set air gap between electrodes of new spark plug
at 0.030" (0.76 mm) (Fig. 32). Next, install
spark plug in cylinder head. Tighten plug to 15
ft–lb (20.4 N m).
4. Push the wire onto the spark plug.

Storage

1. FUEL SYSTEM PREPARATION–
Note: A fuel stabilizer/conditioner is most
effective when mixed with fresh
gasoline.
Add Toro Stabilizer/Conditioner to the fuel tank
(one ounce per gallon of fuel).
Run engine for ten minutes to distribute
conditioned fuel through fuel system.
Stop engine, allow it to cool, and drain fuel tank.

Restart the engine again and run it until it stops.
Either choke or prime the engine, restart it a
third time and run engine until it will not restart.
Dispose of fuel properly. Recycle per local
codes.
DO NOT store STABILIZED gasoline over 90
days.
2. Remove spark plug from cylinder head. Next,
pour two teaspoons of engine oil into spark plug
hole in cylinder head. Install spark plug in
cylinder head, but do not install wire on the
plug. Then pull recoil starter slowly to distribute
oil on inside of cylinder.
3. Lubricate the snowthrower: refer to Lubricating
Snowthrower, page 15. Change crankcase oil:
see Changing Crankcase Oil, page 15.
4. Clean the snowthrower. Touch up chipped
surfaces with paint. Toro Re–Kote paint is
available from an Authorized TORO Service
Dealer. Sand affected areas before painting, and
use a rust preventative to prevent metal parts
from rusting.
5. Tighten all screws and nuts. If any part is
damaged, repair or replace it.
6. Cover snowthrower and store in a clean, dry
place out of the reach of children. NEVER
STORE SNOWTHROWER IN HOUSE
(LIVING AREA) OR BASEMENT WHERE
IGNITION SOURCES MAY BE PRESENT
SUCH AS HOT WATER AND SPACE
HEATERS, CLOTHES DRYERS, AND THE
LIKE BECAUSE GASOLINE AND FUMES
ARE HIGHLY FLAMMABLE,
EXPLOSIVE, AND DANGEROUS IF
INHALED. Allow engine to cool before storing
in any enclosure.
