Maintenance

During all service operations concerning knives and cutting discs the tractor engine must be stopped and the hand brake activated. If the machine is in the raised posi- tion it must be firmly supported. Also refer to page 5, item 10.

Re-tighten the bolts of the cutting discs and knives on your new machine before starting and again after about 1 hour of operation. The same applies when any service work is done, for example, replacing knives.

Knives - cutting discs

The curtain (A) of the machine can be rotated so that there is free access for inspection of cutting discs and knives. Also refer to page 26, Figure 4 - C.

NOTICE

Check daily that the bolts of the cutting discs and knives are tightened, and that cutting discs, cones and knives are undamaged. If the rotating parts are unbalanced, vibrations could occur causing damage to the cutterbar. Damage of this kind voids the warranty.

NOTICE

Keep the cones (B) and (C) on the right hand and left hand sides clean. If the cones are unbal- anced, vibrations could occur causing damage to the cutterbar.

Damaged knives (D) must be replaced immediately. Twisted knives (Standard) may be turned over and used in the same location. If flat knives (Optional) are worn on one side only, they can be interchanged by using the knives from another cutting disc that rotates in the opposite direction. This will allow blades to be used on both sides. Check that bolts (E) and nuts (F) are in good order - if not, they must be replaced.

NOTE: The knives have to be in the position shown (G) to remove the bolts.

Only use original replacement parts. The cutting discs of the machine rotate at 3000 rpm - never compromise with safety.

Operate with safety - note the following:

●The cutting discs are to be fitted in pairs as shown (90° displacement of knives).

●Always use LOCTITE 242 on the bolts of the cutting discs (H).

●Torque setting as stated - make sure that splines and holders are kept clean.

●Special for model HM2007 and model HM2009 with optional flat blade kit: The cutting disc next to the gearbox is different from the others - See page 51 for illustration.
