SNOW BLOWER

 

This is a high-powered machine, with moving parts operating with high energy.  You must operate the machine safely.  Unsafe 
operation can create a number of hazards for you, as well as anyone else in the nearby area.  Always take the following precautions 
when using this machine: 

 

Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people, their property, and 
themselves. 

 

Always wear protective goggles or safety glasses with side shields while using the SNOW BLOWER to protect your eyes from 
possible thrown debris. 

 

Avoid wearing loose clothing or jewelry, which can catch on moving parts. 

 

We recommend wearing gloves while using the SNOW BLOWER.  Be sure your gloves fit properly and do not have loose cuffs 
or drawstrings. 

 

Wear shoes with non-slip treads when using your SNOW BLOWER.  If you have safety shoes, we recommend wearing them.  
Wear long pants while operating the SNOW BLOWER. 

 

Use ear protectors or ear plugs rated for at least 20 dba to protect your hearing. 

 

Keep bystanders at least 75 feet away from your work area at all times.  Stop the engine when another person or pet 
approaches. 

Never overlook the hazards of electricity.  Always follow these precautions: 

 

Never open the Control Box cover.  Never attempt any electrical repairs yourself.  If in doubt, consult a qualified electrician, 
visit our website at www.DRpower.com or contact DR Power Equipment for toll-free support at: 1-800-dr-owner (376-9637) for 
help or information. 

 

Never use an extension cord that is not rated for outdoor use. 

 

Never connect the Cord to the Snow Blower if there is an electrical hazard present. 

 

Never connect the Cord to the Snow Blower in wet conditions. 

 

Never connect the Cord to the Snow Blower with a damaged extension cord. 

 

Always grasp the electrical cord plug when unplugging the cord from the outlet; never pull the plug out by the cord.  Make 
sure your fingers do not touch the metal prongs when plugging or unplugging. 

 

Never Start the Snow Blower unless the electrical cord is plugged into a properly grounded outlet, which supplies 110-120V 
power, and is protected by a 15-amp circuit breaker. 

 

Never tamper with safety devices.  Check their proper operation regularly. 

 

When using an extension cord, keep the connection between the Control Box and the extension cord well away from any 
water. 

Protecting Yourself and Those Around You 

Safety for Children and Pets 

Safety with Extension Cords 

Tragic accidents can occur if the operator is not alert to the presence of children and pets.  Children are often attracted to the 
machine and the snow blowing activity.  

Never assume that children will remain where you last saw them.  Always follow these 

precautions:

 

 

Keep children and pets at least 75 feet from the working area and ensure they are under the watchful care of a responsible 
adult. 

 

Be alert and turn the machine off if children or pets enter the work area. 

 

Never allow children to operate the SNOW BLOWER.
