Repair Parts Manual
ST 224
Gasoline containing up to 10% ethanol (E10) is acceptable for use in this machine.
The use of any gasoline exceeding 10% ethanol (E10) will void the product warranty.
Please read the owner's manual carefully and make sure you
understand the instructions before using the machine.

HOW TO USE THIS MANUAL
This manual is designed to provide the customer with a means to identify the parts on his/her snow
thrower when ordering repair parts. The illustrations may or may not represent the actual assemblies;
therefore, it is not recommended to use this manual as a guide to assemble or disassemble the snow
thrower. Some hardware and parts are drawn larger in order to more readily identify them.
Each snow thrower has its own model number.
The model and serial numbers will be found on a decal attached to the rear of the snow thrower housing.
When ordering parts, always give the following information:
• Product - “SNOW THROWER”
• MODEL NUMBER - “ST224" (96193009601)”
• Part Number
• Part Description
