2. Clean any dirt or dust from the pres-
sure safety valve.
3. Pull the metal ring on top of the safety
valve to ensure the valve will release
air. The pressure safety valve must be
replaced if it cannot be pulled, or if it
leaks after releasing pressure.
Note: The safety valve is preset to
release air if the tank exceeds its maxi-
mum pressure. DO NOT try to adjust
the safety valve pressure setting!
Some water may accumulate in the tank
depending on usage and humidity. Drain
water from the tank daily to increase the
lifespan of the compressor and air tools.
To drain the tank:
1. Leave the tank pressurized and open
the drain valve, shown in Figure 10, to
drain the water out of the tank.
Note: Draining the air from the tank
can be extremely loud. Wear ear pro-
tection when draining the tank.
Draining Tank
The pressure safety valve prevents dam-
age to the tank by releasing pressure when
the tank reaches maximum capacity.
To check the pressure safety valve:
1. Locate the pressure safety valve shown
in Figure 11.
