2. MARKETING OBJECTIVE

Large disc grinders are the markets where Europe is main, and HITACHI products have obtained high evaluation
in power, durability and quality. However, C has supplied the low-price series of 2000 W disc grinders since 1998
posing a challenge to HITACHI's share.
In addition, some improvements are requested to HITACHI's current G23SF series disc grinders because about
ten years passed since their development. To compete with C's low-price series and to correspond to the request
of improvement, the Models G 18SH2, G 18U2, G 23SF2 and G 23U2 have been developed to upgrade and
replace the current Models G 18SH, G 18U, G 23SF and G 23U. In addition, the Models G 18U2, G 23U2 are
with a soft start. The key features of the Models G 18SH2, G 18U2, G 23SF2 and G 23U2 in comparison with the
current models are as follows:
1) Prolonged service life of the carbon brushes
2) Wear resistance of armature coil
3) Dust-proof labyrinth construction
4) Durable ball bearing retainer of the housing
5) New construction to protect grease leakage
