WARNING: 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 (Fig. 1)
WARNING: Risk of Bursting. If the safety valve does not
work properly, over-pressurization may occur, causing air tank
rupture or an explosion.
WARNING: 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 (F) 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 (Fig. 1)
WARNING: 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.
WARNING: 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.
WARNING: 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.
NOTICE: Risk of Property Damage. Drain water from air tank may
contain oil and rust which can cause stains.
1. Set the On/Off switch (A) to OFF.
2. Turn the regulator knob (D) counterclockwise to set the outlet
pressure to zero.
3. Remove the air tool or accessory.
4. Place a suitable container under the drain valve to catch
discharge.
5. Pull ring on safety valve (F) allowing air to bleed from the tank until
tank pressure is approximately 20 psi. Release safety valve ring.
6. Drain water from air tank by opening drain valve (G) on bottom of
tank.
7. After the water has been drained, close the drain valve. The air
compressor can now be stored.
