Read These Instructions Before Assembly

  

Your spreader is designed to be pushed at three miles per hour, which is a brisk walking speed. Slower or faster 
speeds will change the spread patterns. Wet spreading material will also change the spread pattern and flow rate. 
Clean your spreader thoroughly after each use. Wash between the shut off plate and bottom of the hopper. 
 
Ensure that the FRONT of the gear box points to the front of the spreader. The impeller must turn clockwise. 
Reversing the gear box will cause the impeller to turn counter clockwise. Clean the impeller plate after each use. 
Spreading material stuck on the impeller blades will cause uneven spreading. 
 
Gears are permanently lubricated at the factory. Do not open the gear box or dirt may enter. 

 

 

General Safety Information  

Make sure you are appropriately dressed, including 
sturdy footwear. Protect yourself by wearing gloves 
and a dust mask when handling chemical lawn 
products that contain pesticides and herbicides. 
 
 
 

Assembly
