1. Belt Guard. The Belt Guard (A1)
encloses the pulleys and drive belts.
It protects the user from the mov-
ing parts and allows the large pulley
to direct cooling air to the Air Pump
(A2).
Oil Sight Glass. The oil sight glass 2.
shows proper level of the oil. Oil level
should be at center of Sight Glass.
Tank Drain Valve. The Air Tank (A18) 3.
drain valve allows moisture to be
removed from the tank to reduce the
chance of corrosion inside the tank.
Safety Valve. This Safety Valve (A15) 4.
automatically releases air if the Air
Tank (A18) pressure exceeds the
preset maximum.
In an emergency, the ring could be a.
pulled to reduce tank air pressure.
Ball Valve. Air hose attaches to this 5.
valve. Air pressure required by tools
is set by an air pressure regulator.
Regulator and Gauge (Not Included).
Outlet air can be regulated by adjust-
ing the regulator knob. Clockwise will
raise outlet pressure and counter-
clockwise will lower outlet pressure.
Outlet pressure will be displayed on
the regulator’s pressure gauge.
Air Storage Tank. The Air Tank (A18) 6.
is where air pressurized by the Air
Pump (A2) is stored for later use.
Tank Pressure Gauge. The Air Tank 7.
Pressure Gauge (A20) displays the
air pressure in the tank.
