SAFETY PRECAUTIONS

Raise and lock the ladders when travelling on

public roads. No-one should be standing on the

ladders when the machine is moving.

Most farm machinery accidents can be avoided by the

observance of a few simple safety precautions.

Do not permit anyone other than the operator to

ride on the combine.

General and Operating Safety

1. The machine must only be used by a skilled

operator familiar with all the controls and

harvesting techniques on cultivated land with

slopes up to maximum 26% (15°) uphill and

PROTECTIVE DEVICES

Header standard safety latch -- Figure 12

The left-hand header cylinder is standard fitted with a

safety latch which must be lowered onto the cylinder

rod to prevent accidental lowering of the header.

Whenever work is carried out underneath the header,

the latch must be lowered onto the cylinder rod as

shown at A.

When not in use the header safety latch must be

20259

stored as shown at B.

ATTENTION:

Do not use the safety latch A as a support for

the header when travelling along public roads

otherwise damage may occur to the cylinder.

Header additional safety latch -- Figure 13

For certain countries a small safety latch C is fitted

onto the right-hand cylinder. It must be lowered onto

the cylinder rod when driving on public roads to

prevent accidental lowering of the straw elevator.

When a flip-up maize header is attached to the straw

elevator, a special safety latch (provided with the

machine) must be installed and lowered onto the

cylinder rod when driving on public roads.

21108

Straw elevator additional support -- Figure 14

For certain countries there is a legal obligation to have

an additional support F installed on the right-hand

side of the straw elevator. This support must be

placed in position D whenever the machine is driven

on public roads.

When not in use, support F can be stored in bracket E.

When a maize header is attached to the straw

elevator, a special support F

(provided with the

machine) must be installed and used when driving on

21106

public roads.

1-20

SECTION 1

Safety guards -- Figure 21

For safety’s sake and according to European

directives, safety guards now have locking devices

which can only be opened by means of the special

tool located on the left-hand side of the straw elevator,

a wrench (key width 13 mm) or a screw driver.

43037

Straw chopper spreader chute -- Figure 22

The straw chopper spreader chute A must remain in

the operating position (as shown) when driving on

public roads when the combine is not pulling a header

trailer.

42965

Fire extinguisher -- Figure 23

The fire extinguisher is located on the left-hand side

near the straw hood.

Check the operating instructions.

Once the extinguisher is discharged, no matter for

how long, it must be recharged.

into the header 2 towards the auger 3. The auger 3

feeds the crop into the front of the straw elevator 4.
