MAINTENANCE
(Continued)
B. BATTERY:
1. When servicing battery, always connect cables to battery
exactly as they were before removal (ground cable to
battery negative [- or neg.] post). If incorrectly connected,
fuse (if so equipped), will blow and alternator won't
charge battery. If this happens, connect cables correctly
and replace fuse.
2. Never expose engine ignition system to battery power.
If battery cable or any live wire contacts ignition system
ground wire, engine ignition system may be damaged.
3. If external battery charger is used, disconnect positive (+
or pos.) cable from battery to prevent possible damage.
4. See battery manufacturer's instructions for service and

storage.

TIGHTENED.

ADJUSTMENTS

DO NOT MAKE UNNECESSARY ADJUSTMENTS. FACTORY
SETTINGS ARE SATISFACTORY FOR MOST CONDITIONS. IF
ADJUSTMENTS ARE NEEDED, PROCEED AS FOLLOWS:
À À
REMOTE CONTROL
For satisfactory engine performance, engine and equipment
control must be adjusted properly. To check engine control
adjustments, proceed as follows:
A. Set equipment control at "FAST" or "HIGH SPEED" and keep
it in this position.
The engine control lever should touch "HIGH SPEED STOP".
If it does, the controls are adjusted correctly and no adjustment
is necessary.
NOTE: If engine control lever does not touch "HIGH SPEED
STOP", proceed to instruction "B".
B. Loosen clamp screw so remote control cable can be moved
in cable clamp.
C. Move engine control lever so it is touching "HIGH SPEED
STOP" and hold in this position.
D. Tighten clamp screw securely so cable clamp will hold remote
control cable in place when equipment control is used.
The engine controls should now be adjusted correctly. If
additional adjustments are needed, make them at the
equipment control (see equipment manufacturer's
instructions).

ENGINE WARRANTY.
For engine adjustments and/or repairs not covered in this
"OPERATOR'S MANUAL" see "WARRANTY & REPAIR" on Page 6.
(see Figure 7):
STORAGE
NEVER STORE ENGINE WITH FUEL IN TANK INDOORS OR
IN ENCLOSED, POORLY VENTILATED AREAS, WHERE FUEL
FUMES MAY REACH AN OPEN FLAME, SPARK OR PILOT
LIGHT AS ON A FURNACE, WATER HEATER, CLOTHES
DRYER OR OTHER GAS APPLIANCE.
IF ENGINE IS TO BE UNUSED FOR 30 DAYS OR MORE, PREPARE
AS FOLLOWS:
À À

FUEL SYSTEM:

A.
Remove all gasoline from carburetor and fuel tank to prevent
gum deposits from forming on these parts and causing
possible malfunction of engine.
DRAIN FUEL INTO APPROVED CONTAINER OUTDOORS,
AWAY FROM OPEN FLAME. BE SURE ENGINE IS COOL.
DO NOT SMOKE.
B. Run engine until fuel tank is empty and engine stops due to
lack of fuel.
NOTE: If "Gasohol" has been used, complete above
instructions and then put 1/2 pint of gasoline into
fuel tank and repeat above instructions.
NOTE: Gasoline preservative and stabilizer (such as
"Tecumseh Gasoline Preservative"), is an acceptable
alternative in minimizing the formation of fuel gum
deposits during storage. Add stabilizer to gasoline in
fuel tank or storage container. Always follow mix ratio
found on stabilizer container. Run engine at least 10
minutes after adding stabilizer to allow it to reach
carburetor.

DRAIN CARBURETOR
Drain carburetor by pressing upward on bowl drain (see Figure 8),
which is located below carburetor (see Figure 1).
DRAIN FUEL INTO APPROVED CONTAINER OUTDOORS,
AWAY FROM OPEN FLAME. BE SURE ENGINE IS COOL. DO
NOT SMOKE.
NOTE: Do not drain carburetor if using fuel stabilizer.
