2. With the air compressor on level surface, the oil level should be at the red dot on the oil
level sight glass.
3. If oil level is low, remove oil fill plug/breather cap, add enough oil to bring level to the red
dot. Do not over-fill.
4. Replace oil fill plug/breather cap before starting compressor.
DRAINING THE OIL
1. Remove the oil drain plug (oil level sight glass). Allow oil to drain completely.
2. Replace the oil drain plug (we recommend the use of a sealing compound or teflon tape
to avoid leakage). Do not over-tighten.
3. Refill with the recommended oil to the red dot in the oil level sight glass.
OPERATION
BEFORE OPERATING:
1. Check that all nuts and bolts are all snug.
2. Check the quantity and quality of oil (see compressor lubrication, above).
INITIAL BREAK-IN
1. Open (turn the knurled brass knob out, counter-clockwise) the Moisture release petcock
(Z, fig.6 ) on the bottom of the lower air tank to permit
air to escape, so no air pressure builds up in the air
tank.
2. Plug power supply cord into correct power source.
3. Pull up on the On/Off switch lever (
E, fig.1 & 7 ) to
start the compressor.
4. Run the compressor in this no-load condition for 15
to 20 minutes to lubricate the bearings and pistons.
5. Close (turn the knurled knob in, clockwise) the air
tank Moisture release petcock.
6. Pressure will build in the tank and the Pressure switch will stop the pump when it reaches
the pressure set on the regulator. Your compressor is now ready for use.
NOTE
During the break-in period, there may be a slight smell as the electrical motor brushes
seat themselves. This may last for about 5 minutes and is normal.
CAUTION
!
If the compressor does not run properly after 15 minutes of the break-in or if
you notice any abnormalities, please contact the service center.
NOTE
If the Pressure switch fails to shut off the compressor for any reason, each of the
tanks has a safety valve ( pictured at X, fig.6 on the lower tank; and at Y, fig.8 on the
portable ) which will open automaically when pressure in that tank becomes too great.
PORTABLE TANK REMOVAL / INSTALLATION
WARNING
! Before removing or installing the portable air tank, be sure to disconnect air
compressor unit from power source.
