Daily Start-Up Checklist
Before Starting
Perform the following checks before starting the air
compressor.
1. Make sure that nothing is blocking the belt guard,
air openings, or air filter inlet.
2. Pull the ring on all safety valves to make sure the
valves move freely and smoothly.
3. Check the oil level in the pump and add oil if
necessary.
4. Clean or blow off fins or any part of the air
compressor that collects dust and dirt. The air
compressor will run cooler and provide longer
service.
5. Before attaching an air hose or accessory, make
sure the “OFF/ON-AUTO” lever on the pressure
switch is in the “OFF” position.
6. Close the pressure regulator by turning it counter
clockwise.
At Start Up
7. Start the air compressor by moving the
“OFF/ON-AUTO” lever to the “ON/AUTO”
position. Allow the unit to pump up to cut-off
pressure.
TOO MUCH AIR PRESSURE CAUSES A HAZ-
ARDOUS RISK OF BURSTING. CLOSELY MONI-
TOR THE AIR PRESSURE GAUGE OF THE TANK
SO THE MAXIMUM PRESSURE LIMIT IS NOT
EXCEEDED AND MONITOR THE SAFETY
VALVE TO ENSURE EXCESS PRESSURE IS
DISCHARGED. IF PRESSURE CONTINUES TO
BUILD BEYOND SAFE LIMITS, SHUT THE UNIT
DOWN IMMEDIATELY AND TROUBLESHOOT
THE PROBLEM.
8. Check all fittings and piping for air leaks. Even
minor leaks can cause the air compressor to
overwork, resulting in premature breakdown or
unsatisfactory performance.
9. Check for any unusual vibration and noise.
10. Check for oil leaks and correct any leaks found.
11. Check the pressure ratings of the air tools and
accessories being used with this air compressor
before attaching, then adjust the pressure regulator
gauge for that value.
THE AIR COMPRESSOR’S OUTLET PRESSURE
MUST NEVER EXCEED THE MAXIMUM PRES-
SURE RATING OF THE TOOL OR ACCESSORY
BEING USED. IF A PRESSURE REGULATOR IS
NOT USED, DO NOT USE ACCESSORIES RATED
AT LESS THAN 110 PSIG.)
12. Attach air hose and accessory. Your unit is ready
for use.
Compressed air from the unit may contain water
condensation and oil mist. Do not spray unfil-
tered air at an item that could be damaged by
moisture. Some air operated tools or devices
may require filtered air. Read instructions for
the air tool or device.
Shutting Down
13. Set the “OFF/ON-AUTO” lever to the "OFF"
position.
14. Remove the air tool or accessory.
15. Open the outlet valve or pressure regulator and
allow the air to slowly bleed from the air tank. Close
outlet valve when tank pressure is approximately
20 PSIG.
DRAIN AIR TANKS DAILY. WATER WILL CON-
DENSE IN THE AIR TANKS. IF NOT DRAINED,
WATER WILL CORRODE AND WEAKEN AIR
TANKS CAUSING A RISK OF TANK RUPTURE.
16. With tank pressure at approximately 20 PSIG,
open the drain cocks and allow moisture to drain.
Turn the drain cock counterclockwise to open.
NOTE
If the drain cock valve is plugged, release all air
pressure. The valve can then be removed, cleaned
and reinstalled.
17. After the water has been drained, close the drain
cocks. The air compressor can now be stored.
