SERVICE INSTRUCTIONS
GREASE THE ROLLER SPLINE AND ROTOR BEARINGS
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.
1
Locate the greasing panel.
2
Apply 4+ pumps of grease to each nipple.
3
It is recommended to grease all the nipples whilst the engine is
running and rollers are turning to distribute the grease evenly. DO
NOT USE GRAPHITE BASED GREASE.
4
Both front and rear bearings are greased by nipples A and B. The top
and bottom roller splines are greased by nipples C and D.
GREASE THE ROLLER BOX SLIDES
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.
1
Turn the chipper off and remove the ignition keys.
2
Ensure machine has come to a complete stop - remove battery leads.
3
Remove the 6 nuts and washers retaining the roller box guard and
remove guard.
4
Remove the rotor housing blade access hatch as per blade change
procedure.
5
Apply thin grease with a brush directly to the slide surfaces indicated,
including inner cheeks of slider. DO NOT USE GRAPHITE BASED
GREASE.
6
Replace rotor housing blade access hatch then top guard. Refit nuts
and washers.
7
Refit battery leads.
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.
CHECK HOSES
All the hydraulic hoses should be regularly inspected for chafing, leaks and overall good condition. Identify the hoses
that run to the top motor and track motors as 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.
