MINI-DOZER ASSEMBLY (MD120 (MD1200 0 & MD1600 Series) Unpacking the Kit: Care must be exercised in unpacking the Kit to avoid bending or scratching the various components. As the parts are unpacked, unpac ked, lay them out out neatly and and check the parts against the the enclosed Parts List. Lis t. Notify us immediately of any shortages. shortages . Setting up for Assembly: It is best to set the Body in an upright position on the edges of two saw-horses or on top top of a crate. This will allow you yo u to easily wor k around around and underneath the Tractor. NOT E: The directions 'Left 'Left & Righ t' and 'Upper & Lower' referred to in the following instructions are determined by standing behind the Dozer and looking forward. 'Inside' refers to the the side side of a part which is closest clo sest to an imaginary imaginary center line line running down the length length of the Dozer Do zer . 'Outside' refers r efers to the side farthest farthest from the above defined center line. (Remove (Remove Engi ne from Body and and save bolt s.)
