7.2 Equipment Maintenance 

 

WARNING! 

 

The Dieselguard System has no user-serviceable parts. 

All repairs must be carried out by Ampcontrol only

If a fault develops, return the equipment to Ampcontrol for repair. It is 

essential that 

no attempt be made to repair the equipment

 as any 

attempt to dismantle or repair the equipment can 

seriously 

compromise the safety of the unit and voids product warranty

 

It is recommended that the system incorporating the Diesel Machine Monitor be subject to regular 
functional tests at intervals determined by risk assessment or FMEA. These intervals typically coincide 
with periodic maintenance checks and will cover (but not limited to) tests such as: 

 

Calibrating the CH4 detector 

 

Comparing the calibration reading on the CH4 detector to the reading shown on the IDA display 
(if used). 

7.3 Disposal 

 

ENVIRO 

 

The electronic equipment discussed in this manual 

must not be 

treated as general waste

. By ensuring that this product is disposed of 

correctly you will be helping to prevent potentially negative 

consequences for the environment which could otherwise be caused by 

incorrect waste handling of this product.
