PRODUCT NAME
Hitachi Engine Chain Saw
CS 40EA (S)
Models
CS 40EA (PS)
MARKETING OBJECTIVE
As current 38/43 mL chain saws do not comply with exhaust gas regulations, we are selling these products on
credit in North America and according to small-quantity production regulatory limits in Europe. Therefore, we
cannot expand the sales of such products. And in line with the trend toward targeting general users instead of
semiprofessionals for chain saws of the 40 mL displacement class, other companies have been releasing new
products with lower prices. To compete with this situation, we are releasing these two new models.
APPLICATIONS
Sawing various types of lumber.
Examples of application:
• Forestry: Lumbering, cutting off tree branches.
• Gardening: Cutting off tree branches, pruning, trimming.
• Home use: Cutting firewood, rough cutting in do-it-yourself carpentry.
• Leisure: Cutting firewood at camping sites.
• Farm: Cutting firewood, preparing lumber for cultivating mushrooms, cutting off tree branches.
• Carpentry: Rough cutting or cast-away cutting of pillars, back slitting, cutting used lumber, cutting timber.

Page 8: Thorough Instruction To The Customers
Instruct customers to empty the fuel tank and perform idling until the engine stops, in order to burn up any residual fuel in the carburetor before long term storage of the Models CS 40EA (S) and CS 40EA (PS). Should any fuel remain in the carburetor, only the gasoline mixed in the fuel volatilizes during the storage period, thereby clogging the fuel line with two-cycle oil. -
