WARNING
Certain seals and gaskets (e.g. crankshaft oil seal) on
JCB machines contain fluoroelastomeric materials
such as Viton
® , Fluorel TM 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 (572°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 (572°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:
1 Thoroughly wash contaminated area with 10%
calcium hydroxide or other suitable alkali
solution, if necessary use wire wool to remove
burnt remains.
2 Thoroughly wash contaminated area with
detergent and water.
3 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 FLUOROELASTOMERIC MATERIALS.

WARNING
To avoid burning, wear protective gloves when
handling hot components. To protect your eyes, wear
goggles when using a brush to clean components.

WARNING
Arc Welding
To prevent the possibility of damage to electronic
components, disconnect the battery and the alternator
before arc-welding on the machine or attached
implements.
If the machine is equipped with sensitive electrical
equipment, i.e. amplifier drivers, electronic control
units (E.C.U.s), monitor displays, etc., then disconnect
them before welding. Failure to disconnect the
sensitive electrical equipment could result in
irreparable damage to these components.
Parts of the machine are made from cast iron; welds
on cast iron can weaken the structure and break. Do
not weld cast iron. Do not connect the welder cable or
apply any weld to any part of the engine.
Always connect the welder earth (ground) cable to the
same component that is being welded, i.e. boom or
dipper, to avoid damage to pivot pins, bearings and
bushes. Attach the welder earth (ground) cable no
more than 0.6 metres (2 feet) from the part being
welded.
