II. Oil Cylinder Bore
When lubricating cylinder bore, fuel
may spray from spark plug hole. To
prevent serious injury from fuel fires, follow these
instructions:
1. Carefully disconnect spark plug wire and keep it away
from spark plug. See Figures 21 and 22.
• Keep the disconnected spark plug wire
securely away from metal parts where arcing
could occur.
• Carefully attach the spark plug wire to the
grounding post, if provided.
• Disconnect battery at negative terminal first, if
engine is equipped with a DC electric starter.
• Turn all engine switches to “OFF” position.
• Remove ignition key, if provided.
2. Remove spark plug.
3. Squirt 1oz. (30 ml) of clean engine oil into spark plug
hole.
4. Cover spark plug hole with rag to prevent fuel from
spraying from spark plug hole when starter rope is
pulled.
NOTES
For engines equipped with recoil starters proceed to Step 5.
For engines equipped with electric starters proceed to Step 6.
5. Grasp starter cord handle:
a. Pull starter cord handle out slowly using a full arm
stroke.
b. Repeat once. (This will distribute oil throughout the
cylinder to prevent corrosion during storage.)
c. Proceed to Step 8.
6. Push starter button or turn ignition switch key to
“START” position (see equipment manufacturer’s
instructions) to cycle the engine for one to two seconds.
7. Turn ignition switch key to “OFF” position. Repeat
Steps 6 and 7. (This will distribute oil throughout the
cylinder to prevent corrosion during storage.)
8. Remove rag covering spark plug hole.
9. Install spark plug.
10. Carefully disconnect spark plug wire from grounding
post, if provided.
11. Connect spark plug wire to spark plug before attempting
to start engine.
III. Battery
See equipment manufacturer’s instructions for proper
battery storage if machine is equipped with a battery.
X. Preventing Forest, Brush and
Grass Fires
Local, state and federal laws may require use of a spark
arrester to prevent fires. For example, it is a violation of
California Public Resources Code (section 4442) to use or
operate engine on any forest-covered, brush-covered or
unimproved grass-covered land unless engine is equipped
with a spark arrester. Spark arrester must be maintained in
effective working order by owner and/or operator.
To determine if your engine has a spark arrester, locate the
muffler on your engine. For example, the muffler discharge
will have a spark arrester cover that reads “Screen Type
36085”.
If your engine does NOT have a spark arrester, you may
purchase one from your Authorized TecumsehPower
Servicing Dealer. In some cases the muffler may need to
be replaced to allow the spark arrester to be installed.
