Risk of unsafe operation. Unit cycles automatically when
power is on. When performing maintenance, you may be exposed to voltage
sources, compressed air, or moving parts. Personal injuries can occur. Before
performing any maintenance or repair, disconnect power source from the
compressor and bleed off all air pressure.
NOTE: See Operation section for the location of controls.
TO CHECK SAFETY VALVE
Risk of Bursting. If the safety valve does not work properly,
over-pressurization may occur, causing air tank rupture or an explosion.
Risk from Flying Objects. Always wear certified safety
equipment: ANSI Z87.1 eye protection (CAN/CSA Z94.3) with side shields.
Before starting compressor, pull the ring on the safety valve to make sure that the
safety valve operates freely. If the valve is stuck or does not operate smoothly, it
must be replaced with the same type of valve.
TO DRAIN TANK
Risk of Unsafe Operation. Air tanks contain high pressure air.
Keep face and other body parts away from outlet of drain. Use ANSI Z87.1
eye protection (CAN/CSA Z94.3) when draining as debris can be kicked up
into face.
Risk from noise. Always wear proper hearing protection
during use. Under some conditions and duration of use, noise from this
product may contribute to hearing loss.
NOTE: All compressed air systems generate condensate that accumulates in
any drain point (e.g., tanks, filter, aftercoolers, dryers). This condensate contains
lubricating oil and/or substances which may be regulated and must be disposed of
in accordance with local, state, and federal laws and regulations.
1. Set the On/Off switch to "Off".
2. Turn the regulator knob counterclockwise to set the outlet pressure to zero.
3. Remove the air tool or accessory.
4. Pull ring on safety valve allowing air to bleed from the tank until tank pressure
is approximately 20 psi. Release safety valve ring.
5. Drain water from air tank by opening drain valve on bottom of tank.
Risk of Bursting. Water will condense in the air tank. If not
drained, water will corrode and weaken the air tank causing a risk of air tank
rupture.
