WARNING:
When refitting and re-inflating tyre/wheel assemblies, a safety cage should be used
to prevent possible injury. Incorrectly fitted tyres are dangerous. Please make sure
tyre repairs are carried out by experienced tyre fitters.
8.9 Wheels
1.
Each year, lever off the hub cap, remove the split pin and castle nut and remove the
hub.
2.
Check seals, bearings, brake shoes, springs, studs and all other internal parts.
3.
Replace worn parts, re-grease and refit.
Note:
When re-fitting the wheels, tighten the castle nut until resistance is felt (do not over-tighten).
Release the castle nut 1/6 of a revolution and check for movement in the hub; if none, re-fit the split pin.
Note:
At the end of the feeding season, wash the machine down thoroughly, preferably using a power
washer. Grease or oil all lubrication points and open the drain bung on the bottom of the machine.
Changing a wheel
▪
Park the diet feeder on level ground and apply the handbrake.
▪
Fit chocks to opposite wheels to prevent machine movement during the operation.
Loosen the wheel nuts with a wrench, but do not remove the nuts at this stage.
▪
Jack up the diet feeder underneath the axle until the bottom of the wheel is off the
ground. Remove the nuts completely and slide off the wheel.
▪
Refit the wheel, ensuring that the centre of the wheel is properly located on the hub, and
hand-tighten the wheel nuts.
▪
Lower the machine and tighten the nuts to the recommended torque using suitable
equipment.
▪
Check the wheel nuts for tightness after 1 hour of use, and repeat on a weekly basis.
