SERVICE INSTRUCTIONS
NOTE: This should be done regularly. In dirty and dusty conditions or during periods of hard
work it should be weekly. If the bearings and splines are allowed to run dry premature wear will
occur resulting in a breakdown and the need for replacement parts. This failure is not warranty.
Early signs of insufficient grease includes squeaking or knocking rollers.

1. Remove bolt and washer retaining roller box guard and lift guard (see
diagram on page 18).
2. Locate two grease nipples; one in the centre of each roller shaft.
3. Use a pump action grease gun to apply a generous amount of grease
to each roller drive.
DO NOT USE GRAPHITE BASED GREASE.
After applying grease, to penetrate all the bearing surfaces thoroughly,
start the machine and operate the rollers for 20 seconds. Switch off the
machine. Repeat this greasing/running procedure a further 3 times.
4. Close roller box guard making sure that it is located over the retaining
bracket, and ensure bolt and washer are tightened.
