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
(571.6°F) 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 (571.6°F) (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.
