Proper maintenance is necessary to ensure that your Con ned Space Fan operates as
e ciently and trouble-free as possible. By following the instructions in this section you
will be providing the maintenance needed to achieve this goal.
CAUTION: THE ENGINE MAY START SIMPLY BY ROTATING THE
BLADES. ALWAYS REMOVE THE SPARK PLUG WIRE PRIOR TO
WORKING ON THE BLADE SIDE OF THE MOTOR.
OIL CHANGE
Check the engine oil level before each use. e oil should be changed a er the rst three
(3) operating hours and every 50 hours therea er. Oil changes should be performed
more frequently if the fan is being operated in dusty or dirty conditions. Changing the
oil is easier when the engine is still warm (not hot) from a recent running.
