Checking / Adding Engine Oil

WARNING 

Be sure to check the unit 

before operation. If any issue is found, be sure to 

repair it before restarting the unit. Be sure to make 

daily checks before operation. Operating the unit 

without prior inspection could result in death or erious 

injury, or unit damage.

NOTICE

  Unit should be on level before checking oil 

level. When you check oil level after initial operation, 

wait 10 to 20 minutes after stopping engine before 

checking the oil level. 

  1.  Place compressor on a flat, level surface.

  2.  Clean area around oil fill, remove oil level gauge 

(

A

), and wipe it with a clean cloth. 

  3.  Re-insert the oil level gauge fully and pull it out 

again. The oil level should be between LOW and 

HIGH (

B

).

  4.  If the oil level is below LOW, add engine oil to the 

oil filler port (

C

).

  •  While checking oil level, check also for contamination. 

If the oil is found dirty, contaminated or should it be 

changed according to the periodic inspection list, 

change the oil. See 

Maintenance

.

  •  Excessive engine oil supply could cause engine 

output degradation. Therefore, never fill more than 

the HIGH level.

Checking / Adding Compressor Oil

 WARNING 

Refilling of compressor oil.

•  When refilling the separator receiver tank with 

compressor oil, stop the engine, and make sure that 

the pressure gauge indicates 0psi (0bar) and there is 

no residual pressure in it, and then gradually loosen 

the oil filler cap for refilling oil.

•  Should any residual pressure be left in the 

separator receiver tank, hot compressed air and hot 

compressor oil jetting out could cause burning or 

serious injury to persons nearby.

  1.  Place compressor on a flat, level surface.

  2.  After checking and confirming that the residual 

pressure in separator receiver tank is 0 psi (0 bar), 

replenish the tank with compressor to between the 

upper limit and lower limit of oil level gauge when 

the machine is on. See 

Maintenance

.

NOTICE

   Oil level drops when starting operation.

Supply of excessive oil can cause deterioration of oil 

separation performance Never supply oil at a higher 

level than the upper level of oil level gauge.

Checking Coolant Level

 WARNING 

Taking off the radiator cap.

•  Be sure to stop the machine and allow time to 

cool. Then loosen the radiator cap one notch. After 

the coolant water is sufficiently cooled and the 

inner pressure is released, take the cap off. If this 

procedure is neglected, the inner pressure can blow 

off the cap. Steam jetting out of the radiator could 

result in serious burns.

NOTICE

  Continuing operation at low coolant levels 

could result in damage to the radiator.
  1.  Check the coolant level (

D

) in the reserve tank. If it 

is lower than the limit, open the cap and replenish 

the coolant. Level must be kept above LOW mark.

  2.  If there is a little or no coolant in the reserve tank, 

remove the radiator cap and check the coolant 

level. Supply coolant to the radiator and also the 

reserve tank, if necessary. See 

Maintenance

.
