5 .2 Maintenance 



Very little maintenance is required but adherence to a 

 "clean-up" routine will further reduce the risk of fail- 

 ures . 



5.2.1 Chart Recorder 



After each day of use of the Chart Recorder any accumu- 

 lated dust or dirt should be wiped off with a soft cloth. 

 If used under very dusty conditions it may be necessary 

 to remove the works from the cabinet and using low 

 pressure compressed air, blow the dust from the equipment. 

 Removal of the four bottom mounting screws is the only 

 dissassembly required. 



Paper wipers and rubbing alcohol should be used to re- 

 move any spilled ink from metal work. 



Maintenance to the pen and ink supply, paper supply and 

 chart or pen drive mechanisms should be done at regular 

 intervals as specified by the manufacturer's manual 

 (supplied herewith #15-806325-00) . 



5.2.2 Control 



After each day of use of the Control any accumulated dust 

 or dirt should be wiped off with a soft cloth or paper 

 wipes and rubbing alcohol. If used under very dusty 

 conditions it may be necessary to remove the works from 

 the cabinet and using low pressure compressed air, blow 

 the dust from the equipment. Removal of the four bottom 

 mounting screws is the only dissassembly required. 



Maintenance of the tape recorder heads and drive system 

 should be performed at regular intervals according to the 

 manufacturer's manual included herewith. (#78-20EM-lA2) 



The internal battery in the control should not be left in- 

 active for periods exceeding three months. Every 90 days 

 while in storage for periods of greater duration, the 

 control should be operated by internal battery until the 

 minimum voltage is reached, then allowed to charge for 24 

 hours. This will ensure long battery life and consistent 

 discharge capacity.
