MAINTENANCE

WARNING:
Disconnect the compressor from the
power source and remove the
compressed air from the air tank
before performing the maintenance
operations. Allow the compressor to
cool before performing the
maintenance operations.
1. Cleaning the intake filter
Remove the intake filter (Refer to Fig. 1) every 50
hours or once a week and clean the inside of the
intake filter and the filter element with compressed air
(Fig. 7).
Use a phillips screwdriver to disassemble intake filter.
WARNING:
Never clean filter element with a
flammable liquid or solvent.
CAUTION :
Do not operate without the intake
filter.
NOTE: Replace the filter element when it becomes dirty.
2. Draining tank
Drain tank daily or after 4 hours of use. Open drain
fitting and tilt compressor to empty accumulated
water (Refer to Fig. 6).
3. Oil change-oil topping off
(Only for EC12)
CAUTION :
Overfilling with oil will cause
premature compressor failure. Do not
overfill.
(1) Within the first 50 hours of operation, completely
replace the oil of the pumping element. Unfasten
the oil drain cap on the casing cover, drain all the
oil, and screw the cap back on (Refer to Fig. 8 ).
