2004HG HELICAL GEAR RATIO MULTIPLIER INSTRUCTION MANUAL

SELECTION INFORMATION

Read ALL instructions prior to operating unit. Improper maintenance or operation may cause
injury to personnel or reducer failure.

Written authorization from Sterling Electric is required to operate or use this unit in man lift or
people moving devices.

Check to make certain application does not exceed the allowable load capacities published in
the current catalog.

Buyer shall be solely responsible for determining the adequacy of the product for any and all
uses to which buyer shall apply the product. The application by buyer shall not be subject to
any implied warranty of fitness for a particular purpose. Information contained in this manual is
considered correct at the time of publication and is subject to change without notice.

SAFETY ALERT

WARNING: For safety, purchaser or user should provide protective guards over all shaft

extensions and any moving apparatus mounted thereon. The user is responsible
for checking all applicable safety codes in his area and providing suitable guards.
Failure to do so may result in bodily injury and/or damage to equipment.

WARNING: Hot oil or gear units can cause severe burns. Use extreme care when removing

lubrication plugs and vents.

WARNING: Make certain that the power supply is disconnected before attempting to service

or remove any components. Lock out the power supply and tag it to prevent
unexpected application of power.

WARNING: Any brakes that are used in conjunction with this unit must be sized or positioned

in such a way as to not subject the unit to loads beyond the catalog rating.

CAUTION: Test run unit to verify operation. If the unit tested is a prototype, that unit must be

of current production.

CAUTION: If the unit cannot be located in a clear and dry area with access to adequate

cooling air supply, then precautions must be taken to avoid the ingestion of
contaminants such as water and the reduction in cooling ability due to exterior
contaminants. Units located in confined spaces may require forced air-cooling.

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.
