Pulley and Flywheel - Alignment
The compressor flywheel and motor pulley grooves must be in-line within 1/32" to
assure belt a_ignment within sheave grooves. To check alignment, unplug
compressor and remove the beltguard. Place a straight edge against the outside of
the flywheel and measure the distance from it to the nearest groove. Alignment is
achieved when the other end of the straight edge is within 1/32" of the measured
dimension at the pulley grooves•
Servicing Intake and Exhaust Valves
The intake and exhaust valves as well as the valve plates and cylinder head will,
over a period of time, accumulate a residue of carbon-like material on their
surfaces. The material will decrease the efficiency of the compressor. These
components should be inspected whenever a problem is suspected and cleaned or
replaced with new parts. Use the following procedure to inspect the parts.
1. Unplug compressor and relieve all air pressure from the air tank.
2. Disconnect the pressure release and outlet lines from the air compressor.
3. Remove the hardware securing the cylinder head and remove the cylinder head
and valve plate.
MANY SOLVENTS ARE HIGHLY FLAMMABLE AND A
HEALTH HAZARD IF INHALED. ALWAYS OBSERVE THE SOLVENT
MANUFACTURER'S SAFETY INSTRUCTIONS AND WARNINGS.
4. Clean carbon deposits in head cavities and valve plates with lacquer thinner or
other suitable solvent.
5. Clean the intake and exhaust valves with lacquer thinner or other suitable
solvent. Inspect valves; replace if necessary.
NOTE
DO not use gasket cement on any gasket surface as this may clog
compressor valve cavities and air flow areas.
6. Reinstall valve plate and gaskets.
7. Install the cylinder head. Snug mounting screws and studs tight, then torque to
25 to 30 foot pounds starting at the center and working toward the outside.
8. Reconnect the pressure release and outlet lines to the compressor pump.
STORAGE
1. Review the "Maintenance" section on the preceding pages and perform sched-
uled maintenance as necessary.
2. Set the "ON/AUTO" lever to "OFF".
3. Turn the regulator counterclockwise and set the outlet pressure to zero.
4. Remove the air tool or accessory.
5. Pull ring on safety valve allowing air to bleed from the tank until tank pressure is
approximately 20 psi. Release safety valve ring.
6. Drain water from sir tank by opening drain cock valve on bottom of tank.
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.
7. After the water has been drained, close the drain cock or drain valve.
