Suspension Rubber Dampers (optional)

If the shock absorbers loose their efficiency, they should be replaced.
1. Connect the sprayer to a tractor to prevent overbalancing.

Change of Tyres

€
DANGER! If it is time to change tyres, it is recommended to leave this job to a specialist and follow the rules below.
Some mounting instructions are usually printed on the tyre itself.
• Always clean and inspect the rim before mounting a new tyre.
• Always check that the rim diameter corresponds exactly to the rim diameter moulded on the tyre.
• Always inspect the tyre inside for cuts, penetrating objects or other damages. Repairable damages should be repaired
before installing the tube. Tyres with non-repairable damages must never be used.
• Also inspect the tyre inside for dirt or foreign objects. Remove this before installing the tube.
• Always use tubes of recommended size and in good condition. When fitting new tyres, always fit new tubes.
• Before mounting, always lubricate both tyre beads and rim flange with approved lubricating agent or equivalent
anticorrosion lubricant. Never use petroleum based greases and oils, because they may damage the tyre. Using the
appropriate lubricant will prevent the tyre from slipping on the rim.
• Always use specialised tools for mounting the tyres as recommended by the tyre supplier.
• Make sure that the tyre is centred, and that the beads are perfectly seated on the rim. Otherwise tearing of the bead
wire may occur.
• Inflate the tyre to 1-1.3 bar (14.5-19 psi), then check whether both beads are seated perfectly on the rim. If any of the
beads do not seat correctly, deflate the assembly and re-centre the beads, before starting inflation of the tyre. If the
beads are seated correctly on the rim at 1-1.3 bar (14.5-19 psi), inflate the tyre to a maximum of 2.5 bar (36 psi), until
they seat perfectly on the rim.
• Never exceed the maximum mounting pressure moulded on the tyre!
• After mounting tyres adjust inflation pressure to operation pressure recommended by the tyre manufacturer.
• Do not use tubes in tubeless tyres.
€
DANGER! No observance of mounting instructions will result in a bad seating of the tyre on the rim, and it could cause
the tyre to burst leading to serious injury or death! DANGER! Never mount or use damaged tyres or rims! Use of a
damaged, ruptured, distorted, welded or brazed rim is not allowed!
