Chemicals
Certain seals and gaskets (e.g. crankshaft oil
seal) on JCB machines contain fluoroelastomeric
materials such as Viton®, FluorelTM and
Technoflon®. Fluoroelastomeric materials subjected
to high temperatures can produce highly
corrosive hydrofluoric acid. This acid can severely
burn. New fluoroelastomeric components at
ambient temperature require no special safety
precautions. Used fluoroelastomeric components
whose temperatures have not exceeded 300°C
require no special safety precautions. If evidence
of decomposition (e.g. charring) is found, refer
to the next paragraph for safety instructions.
Do not touch component or surrounding area.
Used fluoroelastomeric components subjected to
temperatures greater than 300°C (e.g. engine fire)
must be treated using the following safety procedure.
Make sure that heavy duty gloves and special safety
glasses are worn: Thoroughly wash contaminated
area with 10% calcium hydroxide or other suitable
alkali solution, if necessary use wire wool to remove
burnt remains. Thoroughly wash contaminated area
with detergent and water. Contain all removed
material, gloves etc. used in this operation in
sealed plastic bags and dispose of in accordance
with Local Authority Regulations. Do not burn
fluoroelastiometric materials.
Hydraulic Hoses
Never re-use hydraulic hose end crimps or use
reusable hose end crimps.
Personal Protective Equipment
Use the appropriate personal protective equipment
before performing maintenance on the machine,
otherwise you could be injured.
