Avoid sudden jars, such as placing upon the table 

 or into the case with force. 



Remove any Canada balsam or cedar oil which may 

 adhere to any part of the stand with a cloth moistened 

 with benzole and wipe dry with chamois. 



Use no alcohol on any part of the instrument as it 

 will remove the lacquer.. As the latter is for the 

 purpose of preventing oxydization of the metals, it is 

 important to observe this rule. 



To use the draw-tube impart the spiral motion. 



To lubricate any of the parts, use a slight quantity 

 of soft tallow or good clock oil, or paraffine oil. 



If the pinion works loose from the jar incident to 

 transportation or long use, which sometimes occurs to 

 such an extent that the body will not remain in position, 

 increase its tension by tightening the screws on pinion 

 cover. 



Occasionally withdraw the tube from the arm, wipe 

 clean and lubricate both slides. This is highly important 

 as the slides being constantly exposed become dusty 

 and the lubricant is inclined to gum. 



Apply a small quantity of soft tallow or good clock 

 or paraffine oil to a cloth, wipe well over the surfaces 

 and remove the superfluous amount with a dry cloth or 

 Japanese paper. If the lubricant becomes gummy, 

 remove by wiping with a small quantity of benzine or 

 benzole applied to cambric.
