General Operation
1.
Run the motor which drives the reducer and check the direction of reducer output rotation.
Consult motor nameplate for
instructions to reverse the direction of rotation.
2.
Attaching the load:
On direct coupled installations, check shaft and coupling alignment between speed reducer 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 speed reducer output or
the driven mechanism.
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 to a rigid flat surface using grade 5 or higher fasteners. The mounting fasteners should be the largest standard size that
will fit in the base mounting hole. Shim as required under flange or base feet which do not lie flat against the mounting surface.
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 on page 5. 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.

(BISSC)
units with Enviro-Seal do not use vents. See (Enviro-Seal) under
Lubrication
for further infor-
mation.
3.
WASHGUARD

(BISSC)
units include synthetic oil and an Enviro-Seal pre-installed at the factory. It is not necessary to vent these
units, and they can be used as supplied from the factory. Do not loosen the nut holding the stem of the Enviro-Seal, and do not block
the hole in the stem. Do not blow pressurized air into the hole, and avoid spraying washdown chemicals directly into the hole.
4.
Connect motor to speed reducer.
Depending upon gear geometry and operating conditions worm gear reducers may or may not backdrive.
Special consideration should be given to high inertia loads connected to the output shaft. Consult the
factory for further details.
DO NOT CHANGE MOUNTING POSITIONS WITHOUT CONTACTING FACTORY.
Altering the mounting position may require special lubrication provisions which must be factory installed.
Do not operate the reducer 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.
WASHGUARD

units are
lubed and sealed for life, so in most applications it will not be necessary to drain or re-fill the unit.
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 - Standard Units
All standard reducers ordered from the factory are filled with synthetic lubricant to operate within a -10° to105° F ambient temperature
range. Double reduction units have separate oil sumps and must be filled/checked independently. Prior to startup, verify that the oil is at
the level shown on the drawings on page 5.
Enviro-Seal: WASHGUARD

(BISSC)
and stainless steel reducers come standard with an Enviro-Seal and synthetic oil pre-installed
at the factory. It is not necessary to vent these reducers, and they can be used as supplied from the factory.

Instruction Manual
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.
Do not mix different oils in the reducer. Oils should be compatible with Viton® seal material.
