Check all terminal 

connections and 

conductors. 

Tighten loose connections. 

Replace conductors with damaged 

insulation & frayed wiring.

 For 

drilling rigs, this should be done 

with every rig re-location.

 

 

 

 

Inspect 

contactor contacts.

If badly pitted, burned or welded 

shut, replace with factory supplied 

contactor.

For drilling rigs, this 

should be done with every 

rig re-location.

   

 

 

Check Fuses 

are printed on the circuit board. 

Always ensure a backup fuse is 

available on the PCB.

 For drilling 

rigs, this should be done with 

every rig re-location. 

   

 

 

 

Mechanical

 

     

 

 

Inspect the Pressure Release Valve 

label indicator for signs of rupture 

and degradation. If any fluid 

leakage occurs from the heater, 

disconnect it from the power 

supply and have the core replaced 

immediately.

 For drilling rigs, 

this should be done with every 

rig re-location. 

   

 

 

Check all enclosures  

must be clean, dry and free of 

foreign materials.

 For drilling 

rigs, this should be done with 

every rig re-location.

   

 

 

Check motor shaft 

bearing play 

If the motor does not run quietly 

and smoothly and has excessive 

play replace the motor.

 For 

drilling rigs, this should be done 

with every rig re-location. 

   

 

 

Check for 

fluid  leakage

Do not spray with water 

or solvents.
