2. Specific instructions for customers
(1) Starting and stopping procedures
Thoroughly instruct the customers about the difference between the cold starting procedure and hot
restarting procedure, and also on the importance of starting with the throttle lever set to the idling
position.
(2) Fuel safety
x
The engine used by the Models CS 27EPAP(S) and CS 27EPA(S) is of a two-cycle design. Instruct the
customers to use a fuel mixture of gasoline and two-cycle oil at a ratio of 50 : 1.
x
Instruct the customers to use a container intended for mixing gasoline and oil. The use of resin
containers such as poly tanks and PET bottles may cause failure due to deterioration and melting when
in contact with the fuel mixture.
x
Fuel stored for a long time will degrade and deteriorate. In addition, improper capping may degrade the
fuel in only one day, especially in the summer months. Instruct the customers not to store the fuel
mixture, and only prepare the required amount when necessary.
(3) Chain oil
Instruct the customers to use Hitachi chain saw oil (1 liter) sold separately or commercially available
SAE20 or SAE30 engine oil.
Remind the customers to always replenish the chain oil when replenishing the fuel.
(4) Adjusting saw chain tension
Low saw chain tension may damage the blades or guide bar, and even result in blades being detached
under extremely low tension. In particular, new saw chain tend to quickly elongate; therefore, advise the
customers to frequently adjust saw chain tension.
(5) Storage
Instruct the customers to empty the fuel tank and perform idling until the engine stops, in order to burn up
all residual fuel in the carburetor before long-term storage. If any fuel remains in the carburetor, gasoline
in the fuel mixture will volatilize during the storage period and the two-cycle oil will clog the fuel line. As a
result, the engine will not start up the next time.
