Lubrication & Maintenance
Conveyor Gearcase
Drain oil in a new unit after first two weeks (or not more than 100 hours) of operation, and flush gear case
thoroughly with light oil. Refer to “Lubricant and Hydraulic Oil Specifications” section for proper grade oil
and recommended amounts of lubricant� After initial change, oil should be changed every 2,000 hours of
operation or annually, whichever occurs first.
Check gearcase oil level monthly�
Lubrication of Bearings
Grease in a bearing acts to prevent excessive wear of parts, protects ball races, and balls from corrosion
and aids in preventing excessive heat within the bearing� It is very important the grease maintain its
proper consistency during operation. It must not be fluid and it must not channel.
Make sure all fittings are thoroughly cleaned before grease is injected. Points to be lubricated by means
of a grease gun have standard grease fittings.
Lubricate bearings by pumping grease slowly until it forms a slight bead around the seals� This bead
indicates adequate lubrication and also provides additional protection against the entrance of dirt�
Fasteners
Tighten all screws fasteners to recommended torque’s after first week of operation and annually thereafter.
If loose fasteners are found at anytime, tighten to recommended torque� Replace any lost or damaged
fasteners or other parts immediately� Check body mounting hardware every week�
Clean Up
NOTICE!
High pressure wash can inject water and/or fertilizer into control components, causing damage�
Use caution when cleaning these areas�
Thoroughly wash unit every two to three days during the operating season to maintain minimal maintenance
operation� Hose unit down under pressure to free all sticky and frozen material�
It is important the unit be thoroughly cleaned at the end of each operating season� All lubrication and
maintenance instructions should be closely followed� Repaint worn spots to prevent formation of rust�
