Checking cutterbar oil levelRegularly check the cutterbar oil level:- Place the cutterbar in horizontal position (with regards

to X and Y axis)- Remove filler plug (1) and its washer.- Through filling hole, check that the oil level (h) is

comprised between 7 and 8 mm (0.27’’ - 0.31’’).- Top up if necessary.- Clean and reinstall filler plug (1) and its

washer. Replace if necessary.

If it is found that the transmission case is very hotto touch by hand, there is no cause of alarmprovided:

- Lubrication recommendations have beenrespected.

- Discs can be rotated freely by hand whenthe machine is hot.

Before checking that the discs rotate freelyby hand:

- Turn off the engine, remove ignition keyand wait until all moving parts havecome to a complete stop.

Inspection of knives and securing elements

KnivesInspect systematically all knives before the machine isoperated to:

• guarantee the cutting quality.• guarantee safety in use.• Prevent cutterbar damage risks.

Replace knives in the following cases:- Damaged knives. Very rough conditions can cause

knives to crack and become deformed.- Worn knives

Knife length C must exceed 80 mm (3.15’’).Knife width B, measured at a distance A of 10 mm (0.4’’)from the disc edge must exceed 20 mm (0.8’’).The hole L for the securing bolt must not become oval bymore than 20 mm (0.8’’) compared to its originaldiameter.Always replace both knives per disc to avoid creating anout-of-balance force.

Immediately replace worn or damaged parts withoriginal manufacturer parts.

Fixing elementsCheck the fixing elements:- After hitting an obstacle.- When replacing knives.- At the beginning of each season.

The fixing bolts should be changed in the followingcases:- When there is visible warping.- When the locking compound is worn or inoperational.- When the bolt head wear reaches the knife contact

area.- When diameter D of the bolt shoulder is less than

15 mm (0.6’’).- After having been removed 5 times.

Replace nuts in the following cases:- When the contact washer has lost its elasticity.- When the contact washer loosens itself from the nut.- When nut wear reaches = 5 mm (0.2’’).- After having been removed 5 times.

Knife replacement

Clean the nut case.Place a wooden wedge between two discs to stop themfrom rotating.Loosen nut using box wrench supplied with the machine.Remove bolt through opening located at the front of thedisc guard.Knives can be turned over on the same disc to use theother cutting edge or replaced. On each knife, an arrowindicates the disc's direction of rotation.Make sure that the securing nut and bolt are in goodcondition and if necessary, replace them.Torque knife locknut to 7.5 daN m (55 lbf ft).Dull knives require more horse power and have anegative effect on the cut quality.

Disc replacementPlace a wooden wegde (2) between two discs to stopthem from moving.Remove nut (1).Remove the disc.

Replace knife lock-nuts and bolts when theyhave been removed 5 times.Replace systematically all worn or distortedknives. Never straighten a bent knife.Always replace both knives per disc.

4. Storage

At the end of each season- Clean the machine thoroughly.- Drain gearbox and cutterbar and refill with new oil:

See section ’’Lubrication’’.- Make all necessary paint touching ups.- Put the machine under cover in a dry place.- Inspect and replace worn knives and bolts: See

section "Inspection of knives and securing elements".- Slacken V-belts and check their condition.- Release safety breakback lock.- Fully grease the machine.

At the start of each season- Check that all nuts and bolts are sufficiently tightened.- Retension belts.- Reset safety breakback.- Read through the operator's manual again.- Make sure that all protection devices are in place and

good condition.

When replacing the outer cone, make sure toreinstall the cap.

$TROUBLE SHOOTING GUIDE

-

Problem Cause RemedyUneven stubble. Machine tilted to the front or

rear (excessive pitch angle).Adjust cutterbar angle: See section ’’Adjustments in working position’’.

Dull or broken knives. Replace knives.Knives not installed correctly. Make sure the arrow on the

knife upper face is pointing in the disc's direction of rotation.

Too low PTO speed (rotational frequency).

Increase speed to 540 min-1.

Soil build up in front of the cutterbar.

Very wet working conditions. Adjust cutterbar ground pressure.Too much cutterbar down

pressure.Bad ground contour adaptation.

Incorrect main frame setting. Adjust main frame height with regards to the ground.

Excessive ground speed. Reduce ground speed.Insufficient cutterbar ground clearance in "headland turn" position.

Incorrect tractor lift linkage setting.

See machine attachment.

Too long levelling rod adjustment.

Shorten levelling rods.

Considerable vibrations. Check the condition and the presence of the outer disc cone cap.

Immediately replace missing cap.

Too frequent safety breakback release.

Insufficient spring compression.

Increase spring compression: See section ’’Safety breakback"".
