Basic Safety Instructions• Lockout power to the equipment before working on it.• All drive guards and hand rails must be in place.• Check that the plant components are in good working condition prior to plant
start up.• Never remove, disable, defeat or bypass any safety device on the plant.• Make no modifications to your plant without recommendation or approval of a
representative of CEI Engineering or Service department.• Account for all personnel on the job site before starting the plant.• Avoid wearing loose clothing, necklaces, neckties or anything that could become
entangled in rotating machinery.• Avoid or tie up long hair.• Never leave the controls unattended while the plant is in operation.• Never walk on the material stockpiles or in the cold feed bins, to avoid engulfment by
loose feed stock.• Relieve internal pressure before disconnecting any high-pressure line. Thoroughly
tighten all fittings before reapplying pressure.• Keep away from power driven parts, even if they are not moving, unless they are
locked out.• Use extreme caution if you must approach running equipment.
• A written confined space plan, including recognizing and marking all confined spaces on site;
• Procedures to test and monitor the air inside confined spaces before and during all employee entries;
• Procedures to prevent unauthorized entries and to have an attendant outside the space at all times;
• Effective controls of all existing atmospheric or safety hazards inside the confined space;
• Employee and supervisor training on safe work procedures, hazard controls, and rescue procedures; and
• Effective rescue procedures which are immediately available on site.
Section 1

Maintenance Schedule
DailyCheck the belt tension – belt tension is measured by deflection. Measure the dis-tance between the sheave center lines (perpendicular to the belts) and parallel to thebelt. The belt deflection should be approximately " for each inch of span.
Note: When adjusting belt tension make sure the motor sheave remains parallel to the belt path. Tightening one slide base bolt more than the other can cause mis-alignment.

Monthly• Check the Bushings and Bearing for wear
TroubleshootingIf the belts are slipping, smoking and/or smelling an AC plug (AC that has cooledto a too stiff state for easily flow) may have develops within the pump. The AC plugwill cause the pump to seize causing the belt slippage, smoking or smell.
1. Remove and lock out power to the pump motor.2. Isolate the pump via inflow and outflow valves.3. Disassembly the pump, clear the plug then reassembly the pump. Be sure to
check the V-Belt(s) tension (see daily maintenance below).4. Open the closed valves, remove the lock out and reapply power.5. Verify AC flows through the pump.
Parts Replacement1. Stop operations then lock-out tag-out the system power.2. If necessary, remove the belt guard.3. If necessary, loosen the belt tension using the slide base bolts under the motor.4. Go to the heading below for the item being replaced.

Belts1. Remove the worn belts and inspect the groves on both sheaves. Clean or
replace the sheaves as necessary.2. Install the new belts.3. Adjust the belt tension – belt tension is measured by deflection. Measure the
distance between the sheave center lines (perpendicular to the belts) andparallel to the belt. The belt deflection should be approximately " for eachinch of span.
4. Re-install the belt guard and remove the lock-out tag-out. Restart operations.
Motor1. Remove the electrical access cover on the motor and label the incoming wires.
Disconnect the wires and conduit and remove them from the motor.2. Remove the belts. Take the sheave off the motor shaft.3. Remove the nuts and washers holding the motor in place then remove the
motor.4. Install the new motor using the nuts and washer removed above. Remove the
electrical access cover on the motor, connect the conduit and connect thewires labeled above. Re-install the electrical access cover.
5. Re-install the sheave and belts.6. Do steps 3 and 4 under Belts (above).
Pump1. Place a drip pan or absorbent material under the pump assembly and close any
isolation valves.
2. Let the system cool before proceeding. Hot oil can cause severe burns.3. Support the surrounding components then disconnect all plumbing attached
to the pump.4. Remove the sheave.5. Remove the nuts and washers holding the pump in place then remove the
pump. Discard the gaskets between the pump and other connections.6. Install the new pump and new gaskets using the nuts and washer removed
above.7. Do steps 3 and 4 under Belts (above).
