before attempting to install, service, relocate, or perform
any maintenance.
1
Checking and changing the oil
Maintain the proper oil level by checking the oil sight glass (1)
daily. Change the oil in the pump every 3 months. Use the following
procedure to change (or add) oil.
□
Run the compressor for ten minutes to warm up the oil if the
unit has not been in use for an extended period of time.
□
Turn the compressor off and disconnect the compressor
from the power source.
□
Position a pan under the pump drain plug (2) to catch the oil.
□
Remove the pump drain plug (2) and allow the oil to collect
in the pan.
□
Reinsert the oil drain plug. Remove the oil fi ll plug (3). Pour
new, unused oil into the pump. Do not overfi ll.
□
Reinsert the oil fi ll plug (3) into position. Return power to the
compressor for use.
2
Checking the ASME safety valve
□
Run the air compressor until it reaches cut-out pressure.
□
Turn the compressor off and disconnect the compressor
from the power source.
□
Put on safety glasses. Protect yourself from fast moving air.
□
Pull on the ring of the ASME safety valve (1). This
releases pressure from the tank. The safety valve should
automatically close at approximately 40 - 50 psi.
If the safety valve does not allow air to be released when you
pull on the ring, or if it does not close automatically, it MUST be
replaced.
3
Draining the tank of moisture
□
Turn the compressor off and disconnect it from the power
source.
□
Release the pressure from the compressor by pulling on
the ASME safety valve. The ASME safety valve should close
at approximately 40 - 50 psi.
□
Open the drain valve (1) underneath the tank. Remaining
air pressure will assist in removing moisture from the tank.
