SPARK ARRESTOR
MAINTENANCE
Daily:
Examine the spark arrestor for any sign of gas leakage, cracks or
significant areas of damage, i.e. dents of more than a few millimetres
in depth.
Three Monthly:
Remove spark arrestor. Tap with a soft mallet to loosen any internal
deposits and shake out. Also by shaking check for any loose internal
baffles.
Six Monthly (or 1500 hours operation, whichever is sooner):
Examine the exhaust discharge in darkness whilst repeatedly loading
and accelerating the engine. If any sparks are observed, the spark
arrestor is not suitable for further use.
Note: Ensure adequate ventilation if this check is carried out in an
enclosed area.
Note: The engine must not be put back into service until any problems
identified by the above checks are rectified.
