Page 36: Rotor Hood Open Procedure
ROTOR HOOD OPEN PROCEDURE To prevent potential accidents and harm to the operator from a spinning rotor, a safety interlock system is incorporated into the rotor upper housing. The safety interlock ensures that the rotor has completely stopped rotating before the rotor housing is able to be opened. 5.8.1 INTERLOCK PROCEDURE: As a warning the interlock lever will chatter if attempting to engage the interlock while the rotor is still spin- ning. -

Page 54: Belt Tension
8.2.9 BELT TENSION The machine is designed with a sheave on the engine shaft, and when engaged with the clutch, is used to drive the rotor plate sheave through a pair of drive belts. When the belt is in disrepair or loose, the ability to efficiently drive rotor may be affected. Therefore it is important to periodically check the condition as well as the tension of the belt. -
Page 55: Sheave Alignment
8.2.10 SHEAVE ALIGNMENT A dual V belt transmits rotational power to the rotor. They must be kept properly tensioned and the sheaves aligned to obtain the expected performance and life. For maximum accuracy, have your sheaves aligned with a laser alignment tool. Contact your dealer for information on laser alignment. -
Page 56: Rotor Blades
8.2.11 ROTOR BLADES: The rotor and ledger blades need to be sharp for the Chipper to perform as expected. Periodic inspec- tion is recommended. Keep the blades sharp to reduce the amount of power required during operation. Watch the sharpness of the blades when processing material with a lot of sand, soil or dirt mixed with it. -
Page 57: Ledger Blades
8.2.12 LEDGER BLADES: Each machine is equipped with a ledger (stationary) blade that acts as a shear for the moving rotor blades. The ledger blade is located on the lower rotor housing, mounted on slotted holes for adjustment. There are 4 usable corners on the blade, when the corner facing the rotor blade rounds over, remove the blade and re-install with a different corner facing the rotor blade. -
Page 58: Twig Breaker
8.2.13 TWIG BREAKER: The Twig Breaker is a breaker tab located on side of the lower rotor housing. The discharge paddle passes around the twig breaker and helps to break the material into smaller pieces and turn it into mulch. Inspect the twig breaker for damage such as gouges, a bent, or missing tooth. A damaged twig breaker should be replaced. -
Page 59: Trouble Shooting
TROUBLE SHOOTING The Wallenstein Trailer Wood Chipper is designed with blades on a rotor to cut, shear and shred wooden mate- rial. It is a simple and reliable system that requires minimal maintenance.
