Safety with Gasoline-Powered Machines 

California Proposition 65 

 

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 and always follow these precautions: 

 

Never run the DR ROTO-HOG Premier Power Tiller 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, 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 are 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 DR ROTO-HOG Premier Power Tiller Engine to cool completely before storing in any enclosure.  Never store the 
machine with gas in the Tank or with gas in a Fuel Container near an open flame or spark such as a water heater. 

 

Never make adjustments or repairs with the Engine running.  Before making an adjustment or repair, shut off the DR ROTO-
HOG Premier Power Tiller Engine, wait five (5) minutes to cool, then disconnect the Spark Plug Wire and keep the Wire away 
from the Spark Plug to prevent accidental starting. 

 

Never check for an ignition spark with the Spark Plug or Spark Plug Wire removed.  Always use an approved Spark Tester. 

 

Never tamper with safety devices.  Regularly check their proper operation. 

 

Never change the Engine Governor settings or modify the Engine speed.  Modifications will void your warranty. 

 

To reduce fire hazard, keep the Engine and Muffler area free of debris build-up such as leaves, grass, oil, grease, or any other 
combustible material.  Clean the Engine area after each use.

 

 

Never operate the Engine without the Muffler.  Inspect the Muffler periodically and replace if necessary.  If the Engine is 
equipped with a Muffler Deflector, inspect it periodically and replace if necessary. 

 

Never operate the Engine with the Air Cleaner or Cover over the Carburetor Air Intake removed, except for adjustment.  
Removal of such parts could create a fire hazard.  Do not use flammable solutions to clean the Air Filter. 

 

Always check Fuel Lines and Fittings frequently for cracks or leaks, replace if necessary. 

 

Replace rubber Fuel Lines and Grommets when worn or damaged, but do not use over five (5) years.
