Forward :

• This Service Manual is intended as a guide and/or instruction for correct use and maintenance of the breaker, shall be read through very carefully before installation, inspection, maintenance, repair or any other service of the breaker. Keep this manual at the workshop and mobile service vehicle so that it is always at hand. Repurchase it if it is lost.
• The breaker operator’s manual is written to apply for various markets. Therefore, we ask you to disregard the sections which are not applicable to your breakers and/or carriers. Many hours are spent on design and production to make breakers serviceable as efficiently and safely as possible.
• The accidents which occur in spite of this, are mostly caused by the human factor. A safety conscious person and well serviced/maintained breaker make a safe, efficient and profitable combination.
• Therefore, read the safety instructions and follow them. We continually strive to improve our products and to make them more efficient through changes to their design.
• We retain the right to make these changes without committing ourselves to introducing these improvements on products which have already been delivered. We also retain the right to change data and equipment, as well as instructions for service and maintenance measures without prior notice.
