INTRODUCTION

PARTS REQUIRING REGULAR REPLACEMENT

Out of critical hoses that are necessary to secure safety, we designate Very Important Parts (V.I.P) and recommend
that they should be replaced regularly.

INSPECTION AND REPLACEMENT OF OILS AND GREASES

In performing maintenance, it is necessary for the user to familiarize himself with how to handle the machine safely,
cautions to be exercised and inspection/lubrication procedures. Refer to the Operators Manuals as well.
