Assembly 2.3 ADDING COOLANT (DIESEL ONLY) You may need to add coolant before you start the diesel engine. While operating, check the fluid to ensure the level sits between the full and the low marks. Add if necessary. To fill: 1. Remove the top cover. 2. Add a 50/50 mix of water and antifreeze until it reads slightly below the full line. (The antifreeze should drain from the tank into the radiator). 3. Wait 10 minutes and check level again. Refill if necessary. 4.

4 Operation Section WARNING Before operating your machine, be sure you read and understand all safety, controls and operation instructions in this Owner/Operators manual and on your machine. Failure to follow these instructions can result in serious injury or property damage. As with any other piece of outdoor power equipment, getting the “feel” for how your machine operates and getting to know the best techniques for particular jobs are important to overall good performance.
Operation 4.1 FILLING THE TANK WARNING DANGER Handle fuel with care. It is highly flammable. Always use an approved container and fill tank outdoors. Gasoline is highly flammable and its vapors are explosive. To prevent personal injury or property damage: Store gasoline only in approved containers, in well ventilated, unoccupied buildings, away from sparks or flames.
Operation 4.3 STARTING THE DIESEL CHIPPER WARNING Allow the machine to come to complete stop before inspection or servicing. NOTE The Murphy switch system will shut the engine off if the oil pressure is too low or if the engine temperature is too high. If the engine will not run or shuts off for these reasons, consult your local dealer. 4.4 HYD FEED CONTROL WARNING Handle fuel with care. Always use an approved container and fill tank outdoors. CAUTION Move machine to a clear, level area.
Operation 4.4 HYD FEED CONTROL (CONT’D) 3. The controller will also flash service alerts when started. Every 15 hours it will flash (error light blinks 5 times) to sharpen the chipper blades. Every 100 hours it will flash (error light blinks 10 times) to change the engine oil. To reset service alerts, locate light green wire in engine compartment next to the hour meter. Connect green wire to red wire connector for five seconds. NOTE: The RPM sensor on the rotor must flash or the controller won’t work.
Operation 4.6 DIRECTING CHIPPER CHUTE The chipper chute can lock into 44 different positions using the chute rotator. The chipper chute will lock before it revolves over the feed chute area. The discharge cap adjusts how high and how far the chipped material blows. To adjust the chute rotor lift up the rotor lock. Turn the chute rotor until the chute faces the desired position. Let go of the rotator lock and fine tune the position of the rotor until the lock snaps in place.
Operation 4.9 SAFETY BAR OPERATION 4.9.1 Resetting the Chipper 4.9.2 Locking in Travel Position The safety bar located around the chute area will stop the chipper when pushed in. The reset button for this bar sits on top of the chipper chute. To reset the safety bar, push the reset button and the machine will start up again. If false trips occur from a limb, the reset button can be held in to override the system.
