MAINTENANCE
Span Safety Box Cable Adjustment
1. Adjust the fixed end cable mount hook bolts
until both the proper deflection of safety cable
is achieved and the T-bar is perpendicular (90
degrees) to the span pipe. See Figure 83-1.
2. After adjustment, tighten all hook bolt hardware
completely.
Side Inlet Elbow Adjustment
To insure that the swivel inlet elbow works correctly
when the machine is reversed the inlet elbow angle
must be angled away form the cart at approximately
10 degrees. See Figure 83-2.
To adjust the side inlet elbow angle do the following:
1. Loosen jam nuts on 1/2 in x 3 in cap screw at
each stop bracket.
2. Set the side inlet elbow in one direction so that
it angles away from the cart at approximately 10
degrees.
3. Adjust 1/2 in x 3 in cap screw until the head con-
tacts the stop tab on inlet elbow, then tighten the
jam nuts.
4. Repeat steps 2 and 3 for the other direction.
Electric Primer Maintenance
• The Vacuum Pump requires occasional flushing.
Remove the pressure gauge and run 1/4 cup of
flushing solvent (GAST AH225 or equivalent)
through the pump. See Figure 83-3.
• If the pump fails to produce a vacuum when it
is first turned on, a brief warm-up may free the
blades and restore the normal function.
• LUBRICATION: The automatic bearing oiler
should be refilled as needed with a high detergent
automotive engine oil with a viscosity equivalent
to SAE 10W or less. See Figure 83-3.
• AIR FILTER: Clean the air filter regularly. Remove
air filter from its holder and wash thoroughly in
solvent and let dry completely, then re-install air
filter in its holder. Replace replace air filter every
year. See Figure 83-3.
• CONNECTIONS: Be sure all connections be-
tween primer pump and centrifugal pump are
tight.
