These brands normally carry a model number (e.g GW250, DW708 or TGS172) and separate type number (1, 2, 3 etc). Several types of a model may have been available and these often reflect alterations or upgrades that were made. It is therefore often important to check the type number of your product. For example a ‘Dewalt DW707 Type 1’ has different parts to a ‘Dewalt DW707 Type 2’. Normally the type number can be found printed on the rating plate of the product. You can locate the correct drawing by navigating through the categories or searching by model number. Some model numbers have an extra letter on the end (e.g DW997K) so if you are unsuccessful try adding/removing it
