10) Drive Wheels Take up all end play by adjustable collar 

 or washers. Examine pawls for wear. Some are re- 

 versible, making possible longer use. Renew springs if 

 weak. 



11) Miscellaneous Tighten all nuts, straighten levers, and 

 see that all bolts, cotter keys, etc., are in place. Replace 

 worn parts where needed.

Practically all the suggestions for the mower also apply to 



the binder with the following additions: 



1) Canvases See that all rollers work easily, are in good 



repair, and are properly aligned. Anything wrong with 



the rollers will cause trouble with the canvases. Test 



the frame of the machine (either by means of a square or 



by measuring the diagonals) to see that the canvases are 



properly squared to it. If canvases are not squared, 



trouble will result. Replace all broken slats and straps 



on canvases with new ones.
