5.0 Routine Maintenance
The following must be checked at least on a daily basis during use (also see Service
schedule):
• Check engine oil
• Check water level in radiator
• Check debris screen on front of radiator and remove any debris
• Check hydraulic oil level. When the machine is new, the oil level may drop
during initial use. Regularly check and top-up until level settles. If a top up is
required, thoroughly clean around filler cap before removing to help prevent
debris falling into oil tank, top up as required and replace filler cap
• Grease machine. Every 8 hours, one pump of grease to each of the six
nipples at the central grease point manifold located near the control panel
• Check all fasteners are present and assembled to the correct torque
• Check proximity sensors on engine cover, removable hopper and trip bar are
not damaged and working correctly. The trip bar sensor is the most
vulnerable and if severely damaged could result in the trip bar not working
• Check drive belt tension and adjust as necessary
• Check pulleys and taper lock on flywheel shaft
• Check flywheel blades for damage and sharpness. Machine performance is
adversely affected if blades are blunt or damaged. Replace and sharpen
blades as required. Make sure that the blade seat is clean and free of
damage before reassembly. Shims are available to adjust for blade size
reduction after sharpening. Please refer to blade sharpening for size limits,
adjustment shims and setting. Ensure blade fasteners are correctly installed
and tightened to the appropriate torque. Check after 1 hours’ work then
weekly
• Anvil and side anvil are replaceable and double sided. Make sure that the
anvil seat is clean and free of damage before reassembly
• Exercise extreme care to avoid injury when removing and replacing blades
and anvils. The flywheel can turn creating crush and cutting points in and
around the chipping chamber
• Check all hydraulic hoses and fittings after 5 hours’ work. Beware of hydraulic
oil leaks, they can cause serious injury while the engine is running and the
system is under pressure. A leak can easily inject high pressure oil deep into
flesh and blood stream requiring immediate medical attention. DO NOT
CHECK FOR LEAKS WHILE THE ENGINE IS RUNNING. Hoses to the feed
roller hydraulic motors are the most likely to become damaged as they are
constantly moving during use. If hoses are replaced, all seals must be
replaced at the same time. All replacement hoses must be rated to the
pressure of the chipper hydraulic system
• Check top and bottom feed motor bracket bolts weekly
