6 DR® COMMERCIAL LEAF and LAWN VACUUM
Safety with Gasoline-Powered Machines
GASOLINE IS A HIGHLY FLAMMABLE LIQUID. GASOLINE ALSO GIVES OFF FLAMMABLE VAPOR THAT
CAN BE EASILY IGNITED AND CAUSE A FIRE OR EXPLOSION. NEVER OVERLOOK THE HAZARDS OF
GASOLINE. ALWAYS FOLLOW THESE PRECAUTIONS:
• NEVER RUN THE ENGINE IN AN ENCLOSED AREA OR WITHOUT PROPER VENTILATION AS THE
EXHAUST FROM THE ENGINE CONTAINS CARBON MONOXIDE, WHICH IS AN ODORLESS,
TASTELESS, AND DEADLY POISONOUS GAS.
• STORE ALL FUEL AND OIL IN CONTAINERS SPECIFICALLY DESIGNED AND APPROVED FOR THIS
PURPOSE AND KEEP AWAY FROM HEAT AND OPEN FLAME, AND OUT OF THE REACH OF CHILDREN.
• FILL THE GASOLINE TANK OUTDOORS WITH THE ENGINE OFF AND ALLOW THE ENGINE TO COOL
COMPLETELY. DO NOT HANDLE GASOLINE IF YOU OR ANYONE NEARBY IS SMOKING, OR IF YOU'RE
NEAR ANYTHING THAT COULD CAUSE IT TO IGNITE OR EXPLODE. REPLACE THE FUEL TANK AND
FUEL CONTAINER CAPS SECURELY.
• IF YOU SPILL GASOLINE, DO NOT ATTEMPT TO START THE ENGINE. MOVE THE MACHINE AWAY
FROM THE AREA OF THE SPILL AND AVOID CREATING ANY SOURCE OF IGNITION UNTIL THE GAS
VAPORS HAVE DISSIPATED. WIPE UP ANY SPILLED FUEL TO PREVENT A FIRE HAZARD AND PROPERLY
DISPOSE OF THE WASTE.
• ALLOW THE ENGINE TO COOL COMPLETELY AND EMPTY THE COLLECTOR BOX BEFORE STORING
THE DR LEAF AND LAWN VACUUM IN ANY ENCLOSURE. REMEMBER, DECOMPOSING MATERIAL CAN
GENERATE HEAT AND START A FIRE. NEVER STORE THE MACHINE WITH GAS IN THE TANK OR A
FUEL CONTAINER, NEAR AN OPEN FLAME OR SPARK SUCH AS A WATER HEATER.
• NEVER MAKE ADJUSTMENTS OR REPAIRS WITH THE ENGINE RUNNING. DISCONNECT THE SPARK
PLUG WIRE AND KEEP THE WIRE AWAY FROM THE SPARK PLUG TO PREVENT ACCIDENTAL STARTING.
• NEVER TAMPER WITH SAFETY DEVICES. CHECK THEIR PROPER OPERATION REGULARLY.
• DO NOT CHANGE THE ENGINE GOVERNOR SETTINGS OR MODIFY THE ENGINE SPEED.
MODIFICATIONS WILL VOID YOUR WARRANTY.
• TO REDUCE FIRE HAZARD, KEEP THE ENGINE COOLING FAN AND MUFFLER AREA FREE OF DEBRIS
BUILD-UP SUCH AS LEAVES, GRASS, OIL, GREASE OR ANY OTHER COMBUSTIBLE MATERIAL.
• DO NOT OPERATE THE ENGINE WITH THE AIR CLEANER OR THE COVER OVER THE CARBURETOR
AIR-INTAKE REMOVED, EXCEPT FOR ADJUSTMENT. REMOVAL OF SUCH PARTS COULD CREATE A FIRE
HAZARD.

on US Forest Lands. We provide all DR LEAF and LAWN VACUUMS shipped to California and Washington
State with spark arresters. Failure of the owner/operator to maintain this equipment in compliance with state
regulations is a misdemeanor under California law and may be in violation of other state and/or federal
regulations. Contact your local fire marshal or forest service for specific information in your area.
