FIRST AND FOREMOST.. THANK YOU! We thank you so much for having purchased a wood chipper from Yardbeast. We are continuously striving to design and craft high performance chippers that stand out from the rest; to exceed the requirements put forth by customers like you. You can tell the difference of our chipper by their weight and rigidity of its components. We’d like to think that is how a chipper should be made.

Important Safety Measures This machine is designed to be used in compliance with safety regulations contained in this manual. As with any type of motorized equipment, an error or negligence on the part of the operator can cause serious injury. This machine is capable of amputating fingers and hands; it also expels foreign objects with great velocity that can cause damage to a person by facial and exposure. In case of any emergency, attempt to shut off the engine and seek immediate help.
comply with as well as specific safety instructions that will ensure a safe operation of the chipper. This sticker is in place to let you know the chips come out of the discharge flying at very high speed. This decal lets you know that the engine emits chemicals that can cause cancer and reproductive harm. This sticker is mandatory by the State of California. It is very important you must wear eye protection at all times when using the chipper. Debris at feeding point may kickback at high speeds.
This sticker highlights areas where you can get in contact with the power transmission belts, pulleys and other rotating elements. Only access these areas when the chipper is at a complete stop and the engine has been cleared out to be completely turned off. This sticker informs you of the responsibility as an operator to read the manual before engaging with the chipper. Reading the manual is necessary to assess your safety requirements and risks associated with the operation of such a machine.

Assembly Instructions (Hand Tow Kit) The Yardbeast usually arrives in two separate boxes. One is a crate where the chipper is shipped, and the other is a cardboard box where the hand kit or ATV kit is shipped. Before putting together the chipper, we recommend having an extra person to help with the assembly. We also recommend utilizing mechanical type gloves. WARNING: ● Watch for sharp edges when disassembling package components. We recommend utilizing mechanic type gloves with neoprene to avoid cuts. 1.
4. Lift the end of the chipper (chipper frame first) with the help of a piece of 4x2 wood (you can use another material or geometry, as long as it lifts the chipper and is stable). Make sure the chipper is stable, and assemble the rear wheel axle. Fasteners Used Rear Axle On each side 2- 3/8” X 1 G5 Hex Bolts 2- 3/8” Flat Washer 2- 3/8” Lock Washer 2-3/8” Hex Nut Tools Used 2- 9/16” Hex Wrench Torque on Bolts 15 ft-lbs 5. Repeat the process on the other side. As shown in the picture below.
6. Place the wheels on the rear shaft and secure them with the flat washers and cotter pin. Fasteners Used on Rear Wheels On each wheel: 1- Green Thick Washer 1- 3/16” x 1” Cotter Pin Tools Used 1- Plier 1- Small Hammer if cotter pin fits a little rough. 7. Remove the crate floor from the chipper, place something that can hold the chipper at a height and allows for putting the wheels on the front shaft. For illustration purposes we placed a 5 gal industrial grade bucket.
8. Assemble the feed chute and tighten. Fasteners Used on Feed Chute 8- 5/16” X 1 G2 Hex Bolts 16- 5/16” Flat Washer (front and back) 8- 5/16” Lock Washer 8- 5/16” Hex Nut Tools Used: 2- 1/2” Hex Wrench Torque on Bolts 10 ft-lbs 9. To assemble the discharge chute, open up the flanges as shown in the picture, make sure to place a little grease on the base to make the discharge rotate smoother. Fasteners already come preassembled on the discharge base.
10. When assembling the discharge chute, make sure the flange sits on top of the discharge base. Before putting together make sure to rub grease on the surface to improve the rotation. To adjust and eliminate play on the discharge chute, tighten the 4 hex bolts, apply pressure until you are able to rotate the chute but won’t budge.
Assembly Instructions (Trash Arm) At Yardbeast we developed something cool called a Trash Arm. Sometimes if you are chipping in confined spaces, or areas where you need to pick up the chipped material after, you might want to use the trash arm, a simple device designed to carry a trash container up to 45 gallons or up to 110 lbs. of wood chips. This setup makes it incredibly easier to carry around a trash container that would otherwise be very hard to carry, particularly at long distances.
Setting up your Wood Chipper Read and follow all instructions in the manual for more information on this matter. Once you have finished putting together your wood chipper, you must prepare the engine for the first start. Locate the fuel cap on top of the engine and remove it. You should fill the tank with approximately 2.5 liters of clean, fresh fuel. However, due to changes in engine model used on the chipper please confirm proper fuel tank capacity on the engine’s own user manual.
Chipper Features and Controls 19
FEED CHUTE: A maximum of 3-1/2” diameter branches are allowed through the chute. Always keep the debris rubber guard in place as wood pieces may kickback from the inside. WARNING: When operating the wood chipper, always use protective safety equipment; the operation of this machine involves high speed discharge and ricochet of wood debris. IMPORTANT: Never attempt to force the chipping of branches with diameter larger than 3-1/2”.
QUICK LOCK: T he Quick lock is a unique feature to Yardbeast that allows you to quickly inspect the chipper rotor and components. Always make sure this is properly locked before operating the chipper. Engine Controls CHOKE LEVER: The engine is equipped with simplified operation controls. When the engine is cold make sure to move the choke lever to the choke position (pos O ). As the engine starts cranking, move the lever slowly to the open position ( pos.
Wood Chipper Good Practices Good practices for the operator: 1. Check the oil and fuel level before starting the engine. 2. Do not put hands near rotating parts or power inputs . Contact with the chipper and rotating parts –while in operation- can seriously damage fingers, hands . 3. Before operating the chipper , open it. Check and clean the rotor of foreign debris objects , make sure the cutting chamber is empty and free of any foreign material. 4.
13. If any situations occur which are not covered in this manual, be careful and use common sense. Swiftly turn off the chipper and then contact us for further advice on your situation. Chipper Operation The wood material to be chopped enters the cutting chamber through the feed Hopper. The movement of the blade against the anvil produces a scissor cutting effect on the wood instead of impacting directly against it.
Our chippers are fitted with an industrial/commercial grade centrifugal clutch. The main goal of this mechanical element is to provide automatic power transfer from the engine to the rotor. This allows for easy starts, and provides engine protection. If you are chipping and the engine RPM falls below 1,800 RPM, the clutch will automatically disengage, allowing the engine to recover. For any chipper operator, it is a natural reaction to go after the wood piece inside the chute that is stalling the chipper.
Maintenance General guidelines: 1. Always observe safety precautions when performing maintenance on the chipper. 2. The warranty on this wood chipper, does not cover items that have been subjected to wear, misuse or negligence of the operator. To receive any warranty benefits; the operator must have maintained this chipper as indicated on this manual. 3. All settings (blade, anvil, etc.) should be checked at least once before each use. 4. Periodically check all bolts, nuts, safety pins, etc.
● Check blade edge. If need be, regrind blade at 30 deg. angle. ● Regrind anvil ● Check belt tension / wear Engine Maintenance Use only original spare parts for the engine. Other parts may not perform as well thus, damaging the unit. Utilizing unauthorized spare parts may void your warranty. Exhaust Gases Control Maintenance, replacement or repair of devices and emission control elements may be performed by any service center authorized by the engine manufacturer.

Replacing the Belt Tools: Hex Wrench 7/16”, 1/2”, 9/16”, 3/4”. 1. Stop the engine, disconnect the spark plug and check that the engine has stopped completely. 2. Remove the bolts holding the belt shroud in place and remove. 3. Loosen the engine bolts. (fig 2 , step 1) 4. Remove belt tension by turning the engine tensioner bolt counterclockwise. (fig 2, step 2) 5. Push the engine away from the tow bar. 6. Replace belts 7.
Replacing the Blade Tools: Hex Wrench 9/16” Piece of wood (optional) or Something to hold the rotor disk in place. 1. Place a wood piece to secure the rotor from moving.
2. Loosen the bolts on the blade with a hex wrench. 3. Insert a wood piece on the opposite of the rotor previous to replacing the blade. 4. Replace blade. Start by preloading the bolts from the inside out (1,2,3). Once bolts are preloaded, tighten to 25 ft-lbs each bolt. If you don’t have a way to measure torque, just give the bolts a good grip. 5. Make sure the blade, once in place, will not make contact with any other part of the chipper. You may do this by slowly rotating the disk.
We recommend checking our online blog for more service articles at www.yardbeast.com/read-blog Storage of your unit. 1. Care must be taken to prevent rust on the surfaces.
