RECOMMENDED MAINTENANCE

WARNING

All aspects of the installation must conform to the requirements of 

the NEC, including Article 430 (Motor circuits and Controllers), and all 

local codes.

Wherever possible, each motor should be powered from a separate circuit of adequate capacity 

to keep voltage drop to a minimum during starting and running.  Increase wire size where motor is 

located a distance from the power source.  Wire size must be adequate to minimize voltage drop 

during starting and running.  Refer to Tables A and B for suggested wire sizes.  Distances shown 

are one-way between source and motor.  Portable cords, if used, should be as short as possible 

to minimize voltage drop.  Long or inadequately sized cords, especially on hard starting loads, can 

cause motor failure.  All electrical connections in system must be secure to prevent voltage drop 

and localized heating.                                                                                                                        

•  Determine direction of rotation before connecting driven equipment to prevent damage. 

•  To  prevent  bearing  damage,  do  not  strike  shafts  with  hammer  or  other  tool.                                                                                           

• 

If the motor has been damp or wet, then have motor serviced by a qualified motor repair 

shop before operating. 

Recommended Maintenance 

Remove dirt accumulations in and around vent openings, by vacuuming.  

Dirt accumulations 

can cause motor overheating and a fire hazard.

  Enclosed motors can be cleaned with an air 

jet; wear eye protection. 

Periodically inspect the installation.  Check for dirt accumulations; unusual noises or vibration; 

overheating; worn or loose couplings, sheaves and belts; high motor current; poor wiring or 

overheated connections; loose mounting bolts or guards; and worn motor starter contacts.  

Dayton ball-bearing motors without lubrication provision do not require periodic relubrication. 

Where motor has provision for bearing lubrication, lubricate as follows: 

1.  After stopping motor and disconnection power, thoroughly wipe the housing around both of 

the motor bearings, filler and drain  plugs (on   TEFC) ratings, remove fan cover for access 

to plugs).                                                                                                       

2. 

Remove filler and drain plugs and install a 1/8” pipe thread lube fitting in filler hole.                                                                     

3.  Using a low pressure grease gun, pump new grease into motor until it appears at the drain 

hole.                                                                  

4. 

Run motor for several minutes to discharge excess grease.  Shut motor OFF, replace filler 

and drain plugs, and reinstall fan cover. 

  

See Table C for suggested regreasing intervals.
