6.3.4 Check that the spark plug gasket is in good condition, or replace with a new one. Drive it into the
engine with a spark plug wrench to protect thread from being damaged.
NOTE
Installing a new spark plug, after it touch and oppress the gasket, twist 1/2 more turns; as to
a used one, twist 1/2-1/4 more turns.
CAUTION
:
Be sure to tighten the spark plug securely, otherwise it may become very hot and
possibly damage the engine. Never use a spark plug with improper heat range.
7. STARTING UP IN PLATEAU REGIONS
In plateau or regions with high altitude, standard carburetor produces over-dense combination
of fuel and air, resulting in decreased engine performance and increased fuel consumption. To keep
the engine with high performance, install a carburetor main spray nozzle and readjust the adjusting
screw for idle speed. Using in plateau regions frequently with an altitude of over 1380 m, contact
your dealer for replace the carburetor and make adjustment in advance. Even though a proper
carburetor spray nozzle is installed in the engine, the power output of the engine will drop about
3.5% with every 1000 ft increase in altitude. If carburetor replacement and adjustment is not done,
the “plateau-effect” will be more severe.
CAUTION
:
Use the water pump in regions with lower altitude than that the carburetor spray
nozzle is applicable, the engine’s performance will be reduced and it would
overheated, and over-thin combination of fuel and air produce may cause severe
damage of the engine.
8. TRANSPORTATION/STORAGE
WARNING
:
To avoid a fire, make sure to allow at least 20 minutes cooling the water pump
down before transportation or storage in room.
Transport the water pump with the fuel cock turned off; besides, keep it
horizontal to prevent fuel from spilling. Spilled gasoline and gasoline vapor may
ignite.
8.1 Make sure the storage site for the water pump is dry and clean.
8.2 Clean the water pump inside.
If the water pump is used to pump water with mud, sand or heavy debris, deposit of such may
remain inside it. Before storage, operate the water pump to suck into fresh water to wash,
otherwise impeller may be damaged once reuse. Finishing wash, drive off the water drain plug,
then empty the water in the water pump thoroughly, and reinstall the water drain plug.
8.3 Empty the fuel tank.
