F. WHERE TO GET WARRANTY SERVICE
It is recommended that warranty service be performed by the authorized dealer, who sold you the engine, although
warranty service will be performed by any authorized dealers, distributors and warranty stations anywhere in the
United States. When warranty repair is needed, the engine must be brought to an authorized dealer, distributorship or
warranty station's place of business during normal business hours. In all cases, a reasonable time, not to exceed 30
days, must be allowed for the warranty repair to be completed after the engine is received by the authorized dealer,
distributor or service station.
G. MAINTENANCE, REPLACEMENT AND REPAIR OF EMISSION-RELATED PARTS
Only warranted engine replacement parts approved by Makita U.S.A., Inc. should be used in the performance of any
warranty maintenance or repairs on emission-related parts. If other than authorized parts are used for maintenance,
replacement or repair of components affecting emission control, you should assure yourself that such parts are
warranted by their manufacturer to be equivalent to authorized parts in performance and durability. Makita U.S.A.,
Inc., however, assumes no liability under this warranty with respect to parts other than authorized parts. The use of
non-authorized replacement parts does not invalidate the warranty on other components unless the non-authorized
parts cause damage to warranted parts.
