DR  COMMERICAL LEAF and LAWN VACUUM Safety & Operating Instructions 41
End of Season & Storage
Note: Please refer to the engine owner manual for engine-specific procedures.
Change the oil.
If your DR LEAF and LAWN VACUUM will be idle for more than 30 days, we
recommend using a gas stabilizer. This will prevent sediment from gumming up the
carburetor. If there is dirt or moisture in the gas or tank, remove it by draining the
tank. Completely fill the tank with fresh, unleaded gas and add the appropriate
amount of stabilizer or gasoline additive. Run the engine for a short time to allow
the additive to circulate.
Remove the spark plug and pour about 1 ounce of motor oil into the cylinder hole.
Replace the plug and pull the recoil starter rope until you feel strong resistance.
This will coat the piston and seat the valves to prevent moisture buildup.
Clean/replace the air filter.
Clean dirt and debris from the cylinder head cooling fins, blower housing, debris
screen and muffler area of the engine.
Clean out residual debris from the blower hoses and Collector Box.
If the DR LEAF and LAWN VACUUM will be used as a trailer during the end of
season, we recommend that you remove and store the engine in a dry location. See
page 40.
For minimal storage space, you can disassemble the Collector Box by removing the
Rear & Front Panels, Centrifugal Separator (Top), and the Side Panels. The
Collector Box pieces then can be stacked against a wall in a convenient location. See
page 14 for disassembly and re-assembly of the Collector Box.
WARNING! Before performing any maintenance procedure, stop the
engine and disconnect the spark plug wire.
