Maintenance
All maintenance, cleaning and repair operations must be performed with the machine suitably supported, the engine switched off (and cool), and
the ignition keys removed. NOTE: For commercial use, log hours of operation in a maintenance booklet to ensure proper maintenance intervals
and continued service.
Maintenance Schedule
After 1 hour of work
•
Check all nuts and bolt for tightness – retighten if required.
•
Check belt tension and taper lock tightness – adjust /
tighten if required (refer to belt section for details of
adjustment).
Every 8 hours or daily
•
Check all nuts and bolt for tightness – retighten if required.
•
Check belt condition and replace if necessary
•
Check wear and condition of blades – replacing missing, or
damaged blades immediately.
•
Check condition of safety guards – repair or replace if not
performing their function.
•
Check operation of emergency stop control
•
Lubricate rotor bearings
•
Apply grease to the three main rotor bearings. See below
for locations of the grease points.
Blade Condition & Replacement
Over time, the blades on your machine will wear, and performance will deteriorate. It is important that the blades are kept in good condition to
ensure a long service life and to prevent premature wear. Blades should be replaced when either; 2mm has worn off the end of the blade; the
blade has become blunt or damaged; blades are missing. When replacing blades visually inspect the mounting bolts and washers, if applicable.
These are all wearing parts and will require replacement if they become worn to excess.
