Storage
At the end of an aerating season or when the aerator will
not be used for a long period, it is good practice to carry
out the following preventative maintenance.
1.
Clean off any dirt or grease that may have
accumulated on the aerator or any of the moving parts.
2.
Remove the tines and clean out hollow tines. Coat
tines with oil to prevent rusting during storage.
3.
Open the hood and clean out the inside of the machine.
4.
Lubricate all grease fittings.
5.
Store the machine with the roller and castor wheel
standing on a hard, dry surface or board and block the
roller.
6.
Remove PTO drive shaft and store under hood
7.
Paint the roller and touch–up any other scratches on
the paintwork.
8.
Replace any missing or damaged decals.
9.
Store the aerator inside a dry secure building. Inside
storage will reduce maintenance, give a longer
working life and increase the residual value of the
machine. If inside storage is not available, cover with
a heavy sheet or tarpaulin and secure tightly.
