9. MAINTENANCE [How to Service the Air Compressor]
① Drain the lubricating oil in the procedure described in
9.4 .
② Remove the front door (1) [Ref. No. 904] and left door
[Ref. No. 991].
③ Remove the strainer cover. Then remove the oil
strainer and clean it.
④ Replace the oil strainer when overhauling the air
compressor.
Oil Strainer
Strainer cover
Clogging of the oil strainer drops the oil pressure of the air
compressor.
● Vtype
If the oil pressure sensor detects an oil pressure as low
as 12 psi (0.08 MPa) or lower for operation frequency
110 Hz or higher, or 6 psi (0.04 MPa) for operation
frequency less than 110Hz, the air compressor
automatically shutdowns.
● Fixed-speed type
If oil pressure sensor detects an oil pressure as low as
12 psi (0.08 MPa) or lower, the air compressor
automatically shutdowns.
① Drain the lubricating oil in the procedure described in
9.4 .
② Remove the left door [Ref. No. 991] and left panel
[Ref. No. 910].
③ Place an oil pan under the oil filter.
④ Use a filter wrench to loosen and remove the oil filter
from the oil support on the gear case. Remove and
replace the oil filter element.
⑤ Apply clean oil onto the filter O-ring. Tighten the oil
filter until the O-ring surface comes in contact with
the oil filter seating surface.
⑥ Seat the oil filter O-ring by tightening the filter with
both hands. Immediately after the air compressor
restart verify that there is no leaks on the oil filter.
Pan
(Prepare a pan with a size of
approx. (0.8 × 4 × 10 inches
(20 × 100 × 250 mm))
IMPORTANT
Clogging of the oil filter drops the oil pressure of the air
compressor.
● Vtype
If oil pressure sensor detects an oil pressure as low as
12 psi (0.08 MPa) or lower for operation frequency 110
Hz or higher, or 6 psi (0.04 MPa) for operation
frequency less than 110Hz, the air compressor
automatically shutdowns.
● Fixed-speed type
If oil pressure sensor detects oil pressure as low as 12
psi (0.08 MPa) or lower, the air compressor automatically
shutdowns.
