STORAGE
PREPARATION FOR STORAGE
Proper preparation for storage is essential to keep the engine in good condition and looking good. The following
steps will help prevent rust and corrosion from affecting the operation and appearance of your motor pump and
make it easier to start after storage.
•
Before transporting and/or storing the water pump, make sure it cools completely.
•
Transport the water pump with the fuel switch off, in addition to keeping it horizontal to prevent fuel spills.
•
Store this tool in a clean, dry place.
•
Before storage, clean the inside of the water pump. After cleaning, remove the drain plug from the water,
completely empty the water from the pump, and reinstall the drain plug from the water.
•
To reduce the risk of fire, keep your engine and gasoline tank clean by removing debris from cut material,
oil, and grease.
•
Pull the starter handle until you notice resistance and then keep pulling until the steering wheel triangle
mark matches the start screw hole. In this position, the air inlet and exhaust valves are both closed, and this
can prevent internal oxidation of the engine.
•
Cover the water pump to protect it from dust.
CLEANING
If the engine has been running, let it cool for at least half an hour before cleaning. Clean all exterior surfaces,
retouch damaged paint and cover other areas that may rust with a light oil film.
•
Using a garden hose or pressure washing equipment can force water into the air filter or silencer opening.
Water in the air filter will soak the air filter and water passing through the air filter or silencer can enter the
cylinder and cause damage.
•
Water contact with a hot motor can cause damage. If the engine has been running, let it cool for at least
half an hour before washing.
FUEL
During storage, gasoline oxidizes and deteriorates. This makes it difficult to start due to the generation of
sediments during storage, which will obstruct the combustion system subsequently. If this happens, you may need
to repair or replace the carburetor and other combustion system components.
How long gasoline can be left in the fuel tank and carburetor without causing functional problems will vary
depending on factors such as gasoline mixture, storage temperatures, and whether the fuel tank is partially or
completely full. Air in a partially filled fuel tank promotes fuel deterioration. Very hot temperatures or storage
accelerate fuel deterioration. Fuel deterioration problems can occur within a few months, or even less if the
gasoline was not fresh when you filled the fuel tank.
Distributor's limited warranty does not cover damage to the fuel system or engine performance problems
resulting from careless storage preparation.
EXTEND FUEL LIFE DURING STORAGE
You can extend fuel life during storage by adding a fuel stabilizer formulated for that purpose, or you can avoid
fuel deterioration problems by draining the fuel tank and carburetor.
When you add a fuel stabilizer, fill the fuel tank with new gasoline. If only partially filled, the air in the tank will
promote fuel deterioration during storage. If you keep a container of gasoline for refuelling, make sure it contains
only new gasoline.
The steps are as follows:
1. Add fuel stabilizer following the manufacturer's instructions.
2. After adding a fuel stabilizer, run the engine outdoors for 10 minutes to ensure that treated gasoline has
replaced untreated gasoline in the carburetor.
3. For the engine and move the fuel valve to the OFF position.
