Rev: 2.0
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.
Turn the chipper off and remove the ignition keys.
1
Ensure machine has come to a complete stop - remove battery leads.

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
All engine servicing must be performed in accordance with the Engine Manufacturer’s Handbook provided with the
machine.
Failure to adhere to this may invalidate warranty and/or shorten engine life.
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.
Locate the greasing panel.
1
Apply 4+ pumps of grease to each nipple.
2
It is recommended to grease all the nipples whilst the engine is
3
running and rollers are turning to distribute the grease evenly. DO
NOT USE GRAPHITE BASED GREASE.
Both front and rear bearings are greased by nipples A and B. The top
4
and bottom roller splines are greased by nipples C and D.
GREASE THE ROLLER SPLINE AND ROTOR BEARINGS
