Maintenance
Belts
Correct chain tension
Hydraulic system
14.1.2
V-belts must always be correctly tensioned. Oil
contaminated V-belts may be cleaned with a cleansing
fluid. Do not use benzine or similar substances.
Steel roller chains are correctly tensioned when the
empty section of the chain can be depressed in the
middle between the sprockets by thumb pressure by
approx. 2 % of the respective axle distance, whereby
the loaded section of the chain shall carry a light load.
With new chains check the tension more frequently.
Chain that have stretched over the course of time can
be shortened by taking out a double link.
Danger!
Always depressurize the hydraulic tailgate
cylinders before starting to work on the
hydraulic system.
The hydraulic system is under high pressure.
Fluids emerging under high pressure (fuel,
hydraulic oil etc) can penetrate the skin and
cause severe injury. In case of an injury
consult a doctor immediately since this may
cause severe infections.
When searching for leaks use appropriate
means because of the risk of injury.
When working on the hydraulic system
shut the engine down, pull the ignition key
off and secure the combine harvester
against rolling (parking brake, wheel
chocks)!
Check hydraulic hoses at regular intervals
and replace them if damaged or aged!
Replacement hoses must comply with the
technical requirements of the equipment
manufacturer.
Environment!
Catch running-out hydraulic oil and dispose of
environmentally together with the used oil filter.
Repairs in the hydraulic system must only be
performed by CLAAS expert workshops.
