Site Considerations Location The wood chipper must be placed on a firm, flat, grass or dirt surface to prevent the machine from tipping. DO NOT place the machine on concrete, asphalt, or other hard surfaces. The chips could bounce up from the hard surface and cause injury. Working Clearances Consider the length of the material to be processed through the machine and make sure that there is enough height above the wood chipper to accommodate the material.
DO NOT attempt to start this machine until all assembly has been completed. Serious personal injury and damage to the machine could occur. Install Stand (See Figure 1) 1. Position the stand (A) underneath the engine base. 2. Using the four M8x60 bolts (C) and four nuts (D), tighten the stand with the engine base plate. Install the Wheels (See Figure 2) 1. Place the wheel onto the axle (B). Make sure the wheel disc flat side faces the machine. 2. Slide the washer (A) onto the axle against the wheel. 3.
Install Chipper Cone (See Figure 3) 1. Position the chipper cone (B) over the three M8 thread studs protruding from the engine plate. 2. Attach the three M8 flange nuts (C) and tighten to secure the cone. 3. The rubber cone cover (A) can be used when using the vacuum function. Install the Handle (See Figure 4) 1. Position the handle (A) by aligning the handle holes with the hopper holes on the two sides. 2. Using four flange bolts (C) and nuts (D), secure the handle on the hopper.
Before Each Use ⚠WARNING Inspect the unit for any signs of damage or foreign material in the machine. Remove any solid material that may be preventing the unit from operating properly.

Refer to engine manual included with literature packet. Check the air cleaner for dirty, loose, or damaged parts.
Operating Instructions ⚠WARNING Never place your hands, fingers, feet, or any other part of your body close to the Discharge Opening while the Chipper/Shredder is in operation.

Troubleshooting ⚠WARNING Turn OFF the machine, allow all moving parts to come to a complete stop, and disconnect the spark plug wire before moving the machine, emptying the bag, unclogging the inlets or outlets, filling the gas tank, or performing maintenance and repairs. While normal care and regular maintenance will extend the life of your equipment, prolonged or constant use may eventually require that service be performed to allow it to continue operating properly.
