MAINTENANCE
OIL CHANGE
w
Change the oil for the first time after 5 working hours, and then after every 50 working
hours. Change the oil when the engine is hot.
Engine oil can be very hot if it is drained directly after stopping. Therefore let the
engine cool for a few minutes before draining the oil.
w
Remove the drainage plug (fig 3E) and let the oil run out into a container. Replace the
drainage plug.
w
Fill with new oil - SAE 10W-30, approx. 0.6 litres.
AIR FILTER
w
A dirty or blocked air filter reduces engine power and increases wear.
w
Wash the filter every third month or after every 25 working hours, which ever occurs the
first.
Carefully remove the filter insert. If the insert is extremely dirty it should be replaced
or cleaned (fig. 8).
Wash the insert in detergent and warm water. Rinse under running water. Let the
insert air dry completely before refitting. The insert must not be oiled. Do not use
compressed air to clean the insert.
SPARK PLUG
w Clean the spark plug periodically (after every 100 working hours). Use a wire brush to
clean. Set the correct electrode gap (fig. 9).
w Change the spark plug if the electrode is too burnt or if the spark plug is damaged. The
engine manufacturer makes the following recommendations:
For Briggs & Stratton engines a Champion J19LM ought to be used. Electrode gap
0.75 mm.
ROTOR
Lawn rake
w
After a period of time the blades/heads become worn on the side that first enters the
lawn (fig. 10).
w
Loosen the entire rotor unit from the machine and swing axle. When refitting the rotor
unit the blades/heads can be reversed (fig. 12).
w
However, when both sides have been worn new wear parts should be fitted.
