TROUBLE SHOOTING
FAULT
POSSIBLE CAUSE
REMEDY
Cylinder ‘knocks’ while
rotating
High spot on cylinder or bottom blade due
to contact with foreign object
Remove high spot with a stone and back lap
to restore cutting edges. Serious damage will
require re grinding
Worn cylinder bearings
Replace as necessary
One cylinder rotates
slowly
Cutting cylinder bearing seized
Replace as necessary
Incorrect rotation motor fitted
Check motor and replace if necessary
Diverter valve only partly open
Free off and lubricate or replace diverter
valve as necessary
Motor integral check valve jammed open
Have check valve cleaned and checked
Cutting cylinder tight on the bottom blade
Re adjust setting
Cutterhead fails to lift out
of work
Lift cylinder seal failure
Replace seals
Pressure relief valve jammed open or
wrongly set
Have relief valve cleaned and pressure
checked. Consult your authorised dealer
Defective control valve
Overhaul control valve
Mechanical blockage
Remove blockage
Cutterheads do not follow
ground contours
Incorrect hose routing or incorrect
orientation of hydraulic fittings
Move cutterheads throughout extremes of
movement and observe any tightness in the
hoses. Correctly route hoses and orientate
fittings as necessary
Tightness in pivots
Free off and grease as necessary
Control levers in ‘Neutral’ position
Move the control levers to the ‘Down / Cut’
position
Cutterheads fail to start
up when lowered into
work
Low oil level
Fill hydraulic oil reservoir to correct level
Diverter valve jammed
Free off and lubricate diverter valve as
necessary
Pressure relief valve jammed open or
wrongly set
Have relief valve cleaned and pressure
checked. Consult your dealer
Cutting cylinder jammed
Free off as necessary
Cutting cylinder tight on bottom blade
Re adjust setting
Cutterhead control valve in the ‘off’ position
caused by:
- Hydraulic pressure in the override lift
circuit
Operate the override control lever to the
‘Down / Cut’ position
- Back lap control lever not locked in the
‘normal operation’ position
Lock the back lap control lever in the ‘nor-
mal operation’ position
- Mechanical failure of the back lap control
valve or its operating mechanism
Replace or repair as necessary
Hoses wrongly connected
Check hydraulic circuit and reconnect as
necessary
