NOTE: This should be done regularly. In dirty and dusty conditions or during periods of hard work it should be daily.
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.
NOTE: This should be done regularly. In dirty or dusty conditions or
during periods of hard work it should be done weekly. If the slides
become dry the top roller will tend to hang up and the pulling-in
power of the rollers will be much reduced. Excessive wear will ensue.

Both front and rear bearings are greased by nipples A and B. The 4
top and bottom roller splines are greased by nipples C and D.
CHECK HOSES
All the hydraulic hoses should be regularly inspected for chafing and leaks. The hydraulic system is pressurized to 150
Bar (2175 PSI) and thus the equipment containing it must be kept in good condition.
Identify the hoses that run to the top motor. These have the highest chance of damage as they are constantly moving.
If any hydraulic components are changed new seals should be installed during reassembly. Fittings should then be
retightened.
GREASE THE ROLLER BOX SLIDES
ENGINE SERVICING
