Hydraulic Repair Safety
T133509—UN—15APR13
This machine uses a high-pressure hydraulic system.
Possible hazards include:
● Residual pressure could cause sudden movement of
the head, which could result in injuries.
● Working in the “pinch” or “saw” area of the harvester
head while the hydraulic system is active could result
in injury or death.
● Escaping oil under pressure can easily penetrate the
skin, resulting in serious injury.
● Hydraulic oil becomes hot during operation, and if it
comes into contact with the skin, may cause severe
burns.
Avoid the hazards by turning off hydraulic systems
before maintenance or service work is performed.
Always reduce the hydraulic system pressure to zero,
relieving pressure before disconnecting hydraulic lines
or starting to work on any hydraulic component.
Remember to re-tighten all connections before re-
applying pressure.
Under Pressure
If it is necessary to work on the hydraulic system while it
is under pressure (for example, searching for leaks),
always wear gloves, approved eye protection, and full
protective clothing.
T133840—UN—20SEP00
Never search for leaks with your hands: Use a piece
of cardboard to find the location of escaping oil by
holding it over the suspected leak.
Warning: If hydraulic oil penetrates your skin, see a
doctor immediately. Injected oil must be removed
surgically within hours or gangrene may result

Welding Repairs Safety
IMPORTANT: Disable carrier and harvester head
electrical power before welding. Separate
harness connectors from the engine and
vehicle microprocessors.
T133547—UN—15APR13
Avoid welding or heating near pressurised fluid lines.
Flammable spray may eject and cause severe burns if
pressurised lines fail as a result of heating. Do not let
heat extend beyond the work area.
TS220—UN—15APR13
Hazardous fumes can be generated when paint is
heated by welding. Remove paint properly. Do not
inhale paint dust or fumes. Do not use a chlorinated
solvent in areas where welding will take place.
● Remove paint to a minimum of 100 mm (4") from the
area affected by heating. If paint cannot be removed,
use an approved respirator before heating and/or
welding.
● Wear an approved respirator if you sand or grind
paint, to avoid breathing the dust.
● If you use solvent or paint stripper, remove the
stripper with soap and water before welding. Remove
solvent or paint stripper containers and other
flammable material from the area. Allow fumes to
disperse at least 15 minutes before welding or
heating.
Ensure there is good ventilation, and wear eye
