Through prolonged operation, the rotating screen may become clogged with grass and debris.
Clean the screen in line with the engine manufacturers recommendations to avoid over heating
and possible engine damage.
Lubricate the cable every 25 hours of mowing by applying a light oil to the top of the inner wire
and allowing it to gravity drain down the inside. The throttle control lever quadrant should have
medium grease smeared over it to protect it from corrosion and to give a smooth operation.
Check that all nuts, bolts, pins and linkages are secured correctly in place and are in good
condition.
Check the condition of the blades, bolts and cutter assembly regularly. Remember that badly
worn blades will affect grass cutting, catcher fill and cause excessive mower vibration.
It is recommended that you use an authorised Service Agent for any replacement, sharpening or
balancing blade work. Always fit a complete set of blades and fasteners to maintain balance
difficult starting and erratic running is most often
attributable to a dirty, oily or carbonated spark plug.

cleaning with a commercial solvent. Clean and reset
the spark plug gap at 0.7 - 0.8mm (0.030”) every
100 hours of operation.
Always fit the recommended spark plug.
