filter element if required.

Weekly 

• Where the compressor is mounted on a vehicle and located    

 

  outside, it should be operated for at least 15 minutes each    

 

  week (twice a week In damp/cool conditions).

Monthly 

• Check gearbox oil level

 

• Check function of Relief Valve

 

• Remove air filter and clean inside the casing.

 

• Check security of compressor and pipe mountings.

500 hours run time or every 12 months (which ever is sooner)
 

• Change the gearcase oil & filter; see section 5.2 

 

• Drain plugs - clean magnetic part (plug See Fig.6)

Annually 

• Examine the internals of the check valve

 

• Examine pipes and silencers for corrosion and replace as

• Replace Air Filter element

 

• Check Relief Valve function, setting and visually.

Maintenance

5.1 

Schedule

5.2 

Changing the gearcase oil 

- see fig 6

1.  Remove the magnetic drain plugs and sealing washers (can also remove the fill/

level plugs for faster drainage). 
2.  Allow the oil to drain into a can for environmental disposal. 
3.  Change the oil filter.
4.  Clean and then refit drain plugs and re-fill the gearcase with approximately 2.5 

litres of oil.
5.  Ensuring that the TR20 is level, check oil level by removing a fill plug. There should 

be a slight leakage of oil with the plug removed.

The relief valve should be 

operated every 3 months to clear 

the valve seat and check that the 

valve is functional. 

(Ear protection is 

recommended)

NOTE

If the TR20 unit cannot be 

completely drained of oil without 

tilting the unit, it will be sufficient 

to drain as much as possible.

NOTE

500 hours is the maximum oil 

change interval.

NOTE

Drive systems must be maintained in accordance with the manufacturers 

instructions.
