SECTION 1: General Information (continued)
1.2.4. Reducers should be of minimum backlash variety and directly coupled with a
backlash-free connection. If line shafts are used, they must be sized for severe
reversing loads.
1.2.5. When using chain drives, incorporate an idler to eliminate any slack. (Do not use
spring-loaded idlers.) As the cam motion stops and starts, any slack in the drive
changes sides. It is necessary to maintain a constant speed of the input shaft.
Loose belts or chains will cause inertial over-run, causing distorted acceleration
and deceleration characteristics which may cause damage to the unit. Belts and
chains must be sized for severe reversing loads.
1.2.6. Ferguson does not provide guarding for moving parts, such as dials, handwheels,
switch cams, etc. Numerous pinch points do exist on this equipment and the
possibility exists of being struck by a moving part. Since this product is expected to
become part of a further developed machine, it is the customer’s responsibility to
add safety fencing, guarding, light curtains or other protection devices, as
necessary, to protect personnel and property.
NOTE: In the event the unit is damaged, contact Industrial Motion Control’s
Wheeling factory or your local representative, for proper reconditioning or
repair (see sections 1.5 Requesting Service or 1.6 Returning a Unit for Repair).
1.3. Operating Environment – This machine is intended to operate in a clean environment.
Excessive coolant, chips, dust dirt or debris can adversely affect its performance and life.
If this machine does operate in a dirty environment periodic cleaning must be practiced
and careful inspection of seals and accessories is necessary.
1.3.1. For extended storage, remove vents and fill with proper oil. (Refer to section 6)
