Speedaire Operating Instructions
Cast Iron Series
Operation (Continued)
10. If compressor is not used for a long
time period, bleed air from line
and use drain valve to drain water
from the tank. Then, follow the
maintenance schedule.
NOTE: Electric models are equipped
with a pressure switch that automatically
turns the motor OFF when the tank
pressure reaches a preset level. After
air is used from the tank and drops to
a preset low level, the pressure switch
automatically turns the motor back on.
Maintenance
Disconnect, tag and lock out
power source then release
all pressure from the system
before attempting to install, service,
relocate or perform any maintenance.
All repairs should be performed by an
authorized service representative.
FOR EFFICIENT OPERATION:
Perform the following test to verify free
operation of the safety valve weekly and
follow maintenance schedule.
1. Pull ring on safety valve and allow
the ring to snap back to normal
position (See Figure 9). This valve
automatically releases air if the
tank pressure exceeds the preset
maximum.
Figure 9
A large amount of
fast moving air will
be released if the safety valve is actuated
with air pressure in the tank.
Do not attempt to
tamper with this
valve. This valve should be checked
occasionally. If air leaks after the ring
has been released, or the valve is stuck
and cannot be actuated by the ring, the
safety valve must be replaced.
2. With motor OFF and unplugged or
locked out, clean debris from motor,
flywheel, tank, air lines and pump
cooling fins.

Belts will stretch in normal use. Properly
adjusted, a 5-pound force applied to the
belt between the motor pulley and the
pump will deflect the belt about 1/2 inch
(See Figure 10).

TO ADJUST A SECTION DRIVE BELT:
1. Remove belt guard.
2. Loosen the four fasteners holding the
motor to the baseplate.
3. Shift the motor in the proper
direction. The belt must be properly
aligned when adjustment is made.
4. Adjust flywheel or motor pulley so
that the belt runs straight.
5. If necessary, use a gear puller to
move the pulley on the motor shaft.
Tighten setscrew after pulley is
positioned.
6. Attach belt guard.
STORAGE
1. When not in use, store hose and
compressor in a cool dry place.
2. Drain tanks of moisture and
disconnect hose. Hang hose with
open ends down to allow any
moisture to drain.
3. Protect the electrical cord from
possible damage by winding the cord
loosely around the handle of the unit
or coiling the cord up.
