MAINTENANCE
The “KAT” carriage is a heavy duty, robust piece of equipment, and under normal conditions, it will
give you years of trouble free service, if it is operated within the limits of its expected use and if the
following maintenance points are adhered to:
Clean all excess dust and spatter from the carriage regularly. Pay particular attention to the drive
gear and wheel assemblies. Occasionally lubricate the wheel assemblies and the drive gear. A dry
lubricant is preferred, but even light machine oil will help.
INSPECTION
At least once per year, the equipment should be taken out of service, stripped down and all moving
parts should be cleaned, greased and inspected for wear and damage. All cables must be
inspected for breaks and abrasion and must be well secured. All damaged and worn parts should
be replaced. All fastening devices should be inspected for tightness.
The tachometer feed-back encoder sensor assembly located on the back of the motor, should be
inspected for dirt accumulation and cleaned where necessary (an optional lower housing dust cover
is available to reduce the opening of the lower housing, thereby reducing the amount of dirt
contamination to the encoder). It is common for the armature shaft of a fatiguing motor to develop
excessive axial float. This float sometimes causes the tachometer feed-back sensor wheel to rub
on one of the encoder sensor faces, causing damage and failure. Check that the sensor disk is
located centrally within the slot of the encoder sensor when the armature shaft is pressed in and
pulled out. Adjust as necessary. The frequency of this inspection should increase with the
accumulated use and or workload of the gear-motor.
NOTE: These inspections should be performed with greater frequency if conditions and usage
requires.
STORAGE
The “KAT” carriage should be kept in a dry environment with no possibility of impact or damage due
to stacking of heavy objects on top of the “KAT”.
SHIPPING
When shipping the “KAT” carriage, the drive engagement lever must be in the disengaged position
and packing placed under the belly of the lower casting, in between the wheel assemblies but not
resting on the drive gear.
