MAINTENANCE
 Check belt alignment by placing a straight edge across
the front of the large and small pulley as shown in figures
32 and 33. The straight edge should touch the rim of the
large pulley at two places. When viewed from above, the
belt should be parallel with the straight edge.
NOTE: If the belt is misaligned, move the engine toward
or away from the air tanks.
 Check belt tension by squeezing the belt. Using light
pressure, the belt should deflect approximately 1/2 in.
NOTE: If belt tension is not correct, move the engine
toward or away from the pump.
 Once belt tension and belt alignment are correct, retighten
engine bolts and nuts.
 Reinstall the belt guard and secure with nuts, washers
and bolts.
 Replace the removable tank.
STORING THE AIR COMPRESSOR
Store the air compressor with the gas tank empty by running
the air compressor until the gas runs out. Allow 30 minutes
of "cool down" time before storing the machine. Store in a
dry, covered area where the weather can't damage it.
Air Compressor Tanks:
 Release all air from the air tanks.
 Drain all moisture from the air tanks, then close drain
valves.
