Before Starting
1. Before attempting to start, check all connections and fuses.
2. Proper consideration should be given to rotating members: Before starting, be sure keys, pulleys, etc. are securely fastened. Proper guards should be provided to
prevent hazards to personnel while rotating.
3. Other mechanical considerations include proper mounting and alignment of products and safe loads on shafting and gearing.
Staring
1. The motor/gearmotor should be test-started in an unloaded state (because of possible reaction torque, the drive should be securely mounted when starting - even
when unloaded).
2. If the drive unit does not start promptly and run smoothly, disconnect at once.
MAINTENANCE
IMPORTANT - Before servicing or working on equipment, disconnect power source (this applies especially to equipment using automatic restart devices instead of manual restart
devices and when examining or replacing brushes on brush type motors/gearmotors).
Clean regularly to prevent dirt and dust from interfering with ventilation or clogging moving parts.
Brush Type Motors/Gearmotors - The wear rate of brushes is dependent upon many parameters (armature speed, amperage duty cycle, humidity, etc.). For optimum
performance brush type motors and gearmotors need periodic user-maintenance. The maintenance interval is best determined by the user. Inspect brushes regularly for wear
(replace in same axial position). Replace brushes when their length is less than 1/4 in. (7 mm). Periodically remove carbon dust from commutator and inside the motor - this can
be accomplished by occasionally wiping them with a clean, dry, non-linting cloth. Do not use lubricants or solvents on the commutator. If necessary, use No. 0000 or finer sand
paper only to dress the commutator. Do not use solvents on a non-metallic end shield if the product is so equipped.
Products Employing Capacitors - Before servicing motors/gearmotors employing capacitors, always discharge the capacitor by placing a conductor across its terminals before
touching the terminals with any part of your body.
LUBRICATION INSTRUCTIONS
Motor Ball Bearings (not gearhead bearings) - are grease lubricated and do not normally require re-lubircation or replacement for a period of approximately five years if run under
normal operating conditions (defined above). More adverse conditions generally require more frequent servicing. Do not over-grease ball bearings as shortened life can result.
Motor Sleeve Bearings (not gearhead sleeve bearings) - sleeve bearing motors are identified by the presence of oil holes or oilers on the motor endshields. Motor sleeve bearings
should be relubricated every six months or 1000 operational hours (whichever comes first) when used under normal operating conditions as defined above. For motors under (4)
inches in diameter, relubricate with 5-6 drops of SAE No. 10 non-detergent oil. For larger diameter motors, relubricate with 5-6 drops of SAE #20 non-detergent oil. More sever
conditions will require more frequent servicing. Do not over lubricate.
Gearhead Lubrication - Gearmotors consists of a motor portion and a gearhead portion. The previous sections dealt with motor bearings - the following text concerns gearhead
(gear and gear shaft bearing) lubrication.
A. Oil lubricated Gearmotors (identified by the presence on an oil level sight gauge or plug marked "Oil Level"). Oil lubricated gearheads are shipped with a red plastic
plug in their vent holes. When operating under normal operating conditions, check oil level every 4 to 5 months or 600 operating hours - which ever occurs first.
1. Type "1D" Gearheads: These gearmotors are identified by the "1D" appearing after a hyphen in the TYPE box on the nameplate. For example. For example: N__-
1_D- (where the identifying designators are illustrated and a "_" indicates the location of any other number or letter). Refill "-1D" gearheads tot he indicated oil level
with a good quality rust and oxidation inhibited oil conforming to AGMA #5 (SAE#50 non-detergent) with a viscosity range of 918-1122 SUS at 100
o
F, viscosity index
of 90 minimum, and pour point of 0
o
F maximum. Do not over fill.
2. Oil Lubricated Gearmotors other than Type "1D": These gearmotors can be identified as follows: examine the nomenclature in the "TYPE" box on the nameplate: if
any of the combinations of numbers and letters defined below appear after a hyphen, the gearmotor is oil lubricated. (The identifying designators are illustrated and a
"_" symbol indicates the position of any other number or letter).
Refill these gearmotors to oil level indicated on the respective product with a good quality worm gear oil conforming to AGMA #5EP compounded (SAE#90). Do not
over-fill.
3. NOTE: For test and run-in of gearmotors that are applied to equipment for resale, remove red plastic vent hole plug from oil fill vent hole. If gearmotor may be tipped
during shipment, replace plastic plug and include instructions to remove the plug before operating the gearmotor.
B. Grease Lubricated Gearmotors: Grease lubricated gearmotors can be identified as follows: examine the nomenclature in the "TYPE" box on the nameplate; If any of
the combinations of numbers and letters defined below appear after a hyphen, the gearmotor is grease lubricated. (The locations of the identifying designators are
illustrated and a "_" symbol indicates the position of any other number or letter).
The above gearmotors are supplied with sufficient grease to last for the "design life" of the gearmotors. Some right-angle gearheads mayhave oilers on their output
shaft hubs. The oilers should be relubricated every three months with 5-6 drops of SAE#20 non-detergent oil.
