Working Under the Machine
Make the machine safe before getting beneath it.
Make sure that any attachments on the machine
are correctly attached. Engage the park brake (if
installed), remove the ignition key, disconnect the
battery. If the machine has wheels use blocks to
prevent unintentional movement.
Lifting the Machine
Under no circumstances must the engine be run with
the transmission in gear and only one driving wheel
jacked clear of the ground, since the wheel on the
ground will move the machine.
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.
Working at Height
Use appropriate access equipment such as ladders
or a working platform if it is necessary to work at
height to perform maintenance tasks on the machine.
If you do not use suitable access equipment there is
a risk of falling, resulting in personal injury.
