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.

WARNING
Accumulators
The accumulators contain hydraulic fluid and gas at
high pressure. Prior to any work being carried out on
systems incorporating accumulators, the system
pressure must be exhausted by a JCB distributor, as
the sudden release of the hydraulic fluid or gas may
cause injury.

WARNING
Petrol
Do not use petrol in this machine. Do not mix petrol
with the diesel fuel; in storage tanks the petrol will rise
to the top and form flammable vapours.
INT-3-1-6
!M
CAUTION
Do not disconnect the battery while the engine is
running, otherwise the electrical circuits may be
damaged.
INT-3-1-14
!M
WARNING
If you try to charge a frozen battery, or jump start and
run the engine, the battery could explode. Do not use
a battery if its electrolyte is frozen. To prevent the
battery electrolyte from freezing, keep the battery at
full charge.

WARNING
Battery Gases
Batteries give off explosive gases. Keep flames and
sparks away from the battery. Do not smoke close to
the battery. Make sure there is good ventilation in
closed areas where batteries are being used or
charged. Do not check the battery charge by shorting
the terminals with metal; use a hydrometer or
voltmeter.
