grade grinding wheel and check the bal- ance by holding the blade up with a round 18 mm diameter bar inserted in the cen- tral hole. To ensure that it works properly without unusual vibrations any imbalance between the two parts of the blade must be below one gram. This can be easily ascertained by putting a one gram weight on the lightest end of the blade. If it tends to go below the balanced position it means that the balance is correct, while if it stays up then the other end will have to be made lighter. A damaged or bent blade must always be replaced; never try to repair it! ALWAYS USE MANUFACTURERS GENUINE SPARE BLADES ! When re-fitting the blade, always follow the indicated sequence, making sure that the blade’s wings are facing towards the interior of the cutting deck and that the concave part of the cup spring (1) is pressing against the blade. Fully tighten the fixing screw (2). If the shaft hub (3) came off when dis- mantling the blade, make sure that the key (4) is firmly in its right posi- tion. !WARNING! !WARNING!

LAYING ON ITS SIDE In order to easily reach beneath the machine, it can be turned onto its side after having removed the grass-catcher and completely emptied the fuel tank. Having put the machine onto a firm and flat surface, engage the parking brake, put the cutting deck into position «7», firmly grip the steering wheel and the seat, and turn the machine onto its right hand side so that it rests on the grass-catcher (as shown), taking care not to damage plastic parts. Make sure that the machine is stable before starting any work and do not carry out work that may cause it to fall. !DANGER! EN 39 MAINTENANCE
