• Read and follow all instructions carefully.

• Disconnect and lock-out power before installation and maintenance.
Working on or near energized equipment can result in severe injury or death.

• Do not operate equipment without guards in place. Exposed equipment can
result in severe injury or death.

Safety First

High voltage and rotating parts can cause serious or fatal injury. Safe installation,
operation and maintenance must be performed by qualied personnel. Familiariza­tion with and adherence to NEMA MG2, the National Electric Code and local codes
is recommended. It is important to observe safety precautions to protect personnel
from possible injury. Personnel should be instructed to:

1. Avoid contact with energized circuits or rotating parts.

2. Disconnect all power sources before initiating any maintenance or repair.

3. Act with care in accordance with prescribed procedures in handling and
lifting this equipment.

4. Be sure the unit is electrically grounded in accordance with code
requirements.

5. Be sure equipment is properly enclosed to prevent access by children
or other unauthorized personnel in order to prevent possible accidents.

6. Be sure shaft key is fully captive before unit is energized.

7. Avoid contact with capacitors until safe discharge procedures have
been completed.

8. Most units are shipped with oil. Always be sure oil lubricated units are
lled with correct oil to proper level before operating.

9. Provide proper safeguards for personnel against rotating parts and
applications involving high inertia loads, which can cause overspeed.

10. Avoid extended exposure to equipment with high noise levels.

11. Be familiar with the equipment and read all instructions thoroughly
before installing or working on equipment.

• Periodic inspections should be performed. Failure to perform proper maintenance
can result in premature product failure and personal injury.

Installation Instructions

Start-Up

Before operating the reducer or gearmotor, the following must be done:

• Install the drive on a rigid and vibration-free surface.

• Remove the protective coating on the shaft and ange. Use solvent
if necessary.

• Carefully install coupling, sheaves, sprockets, or pinions on shaft.
Mount as close to the shaft shoulder as possible.

• It is preferable to use heat instead of force. Do not hammer on shaft!

• Check shaft alignment when using direct coupling.

• Check shaft parallelism when using belt or chain drive.

CAUTION: Refer to belt manufacturer's recommendation for belt tension.
(Tension should not be applied on chain drives.)

• Check oil level in oil lubricated reducer.

• Install breather plug in the plug hole per recommendations shown on
page (5, 7, or 9) for sizes larger than frame 30.

Maintenance

Safe operation and product performance is improved with periodic inspections. It is
recommended the reducer or gearmotor be inspected every 50 hours of operating
time.

• Check mounting bolts and belt tension (if applicable).

Note: The preventative maintenance list below should be performed every
5000 hours of operating time:

• Check oil level and add oil if necessary.

• Make sure the vent plug pin in the breather is clean.

Lubrication

Primary

Series 3000 CbN gearing is shipped with one of the following synthetic lubricants
per the table below and tted with a magnetic drain. Each reducer is lled according
to the mounting position specied when ordered. Refer to the unit nameplate and
the chart to the right for the mounting position arrangement for your unit.

In the case of synthetic oil, the lubricant does not require changing, but it is
recommended that proper oil level be checked periodically.
