IMPORTANT INFORMATION
In the event of the resale of any of the goods, in whatever form, Resellers/Buyers will include
the following language in a conspicuous place and in a conspicuous manner in a written
agreement covering such sale:
The manufacturer makes no warranty or representations, expressed or implied,
by operation of law or otherwise, as to the merchantability or fitness for a
particular purpose of the good sold hereunder. Buyer acknowledges that it alone
has determined that the goods purchased hereunder will suitably meet the
requirements of their intended use. In no event will manufacturer be liable for
consequential, incidental or other damages.
Resellers/Buyers agree to also include this entire document including the warnings above in a
conspicuous place and in a conspicuous manner in writing to instruct users on the safe usage of
the product.
This instruction manual should be read together with all other printed information such as
catalogs, supplied by Sterling Electric.
GENERAL OPERATION
1. Run the motor, which drives the unit, and check the direction of unit output rotation. Consult
motor nameplates for instructions to reverse the direction of rotation.
2. Attaching the load: On direct-coupled installations, check shaft and coupling alignment
between unit and loading mechanism. On chain/sprocket and belt/pulley installation, locate
the sprocket or pulley as close to the oil seal as possible to minimize overhung load. Check
to verify that the overhung load does not exceed specifications published in the catalog.
3. High momentum loads: If coasting to a stop is undesirable, a braking mechanism should be
provided to the unit output or the driven mechanism.
CAUTION: The system of connected rotating parts must be free from critical speed,
torsional or other type vibration, no matter how induced. The responsibility
for this system analysis lies with the purchaser of the speed reducer.
INSTALLATION
1. Mount the unit using grade 5 or higher fasteners.
2. For shipment, pipe plugs are installed in the unit and a vent plug is packed separately. After
mounting the unit in position, remove the appropriate pipe plug and install the vent plug in
the location shown in the chart under LUBRICATION. On double reduction units both the
primary and the secondary must be vented. Failure to vent the unit can cause premature
seal wear or loss of seal and oil. These conditions are not covered by warranty. Check for
correct oil level. Contact the factory for level and vent recommendations on non-standard
mounting positions.
CAUTION:
Do not operate the unit without making sure it contains the correct
amount of oil. Do not overfill or underfill with oil, or injury to personnel,
reducer or other equipment may result.

CAUTION:
CAUTION:
A unit cannot be used as an integral part of a machine superstructure
which would impose additional loads on the unit other than those imposed
by the torque being transmitted either through a shaft-mounted
arrangement, and any shaft mounted power transmitting device. (e.g.
sprockets, pulleys, couplings)
For safe operation and to maintain the unit warranty, when changing a
factory installed fastener for any reason, it becomes the responsibility of
the person making the change to properly account for fastener grade,
thread engagement, load, tightening torque and the means of torque
retention.
LUBRICATION
All standard helical ratio multipliers ordered from the factory are shipped with standard
compounded lubricant and is good for ambient temperature ranges of 30 F to 104 F. Double
reduction units have separate oil sumps and must be filled and checked independently. Use of
synthetics can cause problems if they are not compatible with the seals or conventional lubes
they replace. Prior to startup, verify that the oil is at the level shown on the drawing
below. If the ambient temperature will be outside the range for the lubricant installed at the
factory, drain and refill the reducer with the proper viscosity lubricant prior to use.
VENT PLUG LOCATION
Before putting the unit into operation, substitute the vent plug for the solid plug at the
position desired. Arrows indicate the recommended vent plug locations.

Change Intervals: Standard compounded lubricants should be changed every six months or
2500 operating hours, whichever comes first. Synthetic lubricants should be changed every two
years or 6000 hours, whichever comes first.
CAUTION:
Oil should be changed more often if the unit is used in a severe
environment. (i.e. dusty, humid)

CAUTION:
In the Food and Drug Industry (including animal food), consult the
lubrication supplier for recommendation of lubricants which are
acceptable to the Food and Drug Administration and/or other authoritative
bodies having jurisdiction.
MAINTENANCE
Your Sterling Electric unit has been tested and adjusted at the factory. Dismantling or
replacement of components must be done by Sterling Electric to maintain the warranty.
Frequently check the oil level of the unit. If oil level is low, (refer to the vent and level position
chart) add proper lubrication through the filler plug until it comes out the oil level plug.
Inspect vent plug often to insure it is clean and operating.
CAUTION: Mounting bolts should be routinely checked to ensure that the unit is firmly
anchored for proper operation.
CLASS OF SERVICE
All capacity ratings are based on American Gear Manufacturers Association (AGMA) Standards.
Load conditions must be within cataloged ratings published in the current Sterling Electric
Catalog (available upon request).
LONG-TERM STORAGE (6 MONTHS UP)
Units must be stored indoors, in a dry, warm temperature.
Completely fill the unit with oil.
Rotate the input shaft so that the output shaft rotates at least one revolution per month.
Completely cover the input and output shaft with grease.
At the time of start up, drain the storage oil, install the breather, and fill to the proper oil level
with correct lubricant for the operating condition.
WARRANTY (LIMITED)
The warranty will cover all of the parts in the gearmotor or reducer unit for 12 months from the
date of shipment.
The warranty is only for parts and labor. In no event shall our liability exceed the original price
of the unit, nor does it cover cost of on site repair, installation, or freight.
Contact the service department for a complete explanation as to the full warranty policies and
conditions of sale.
All dimensions designs and specifications are subject to change without notice
