2 Section Assembly WARNING Before inspecting or servicing any part of this machine, shut off skid steer, disconnect the hydraulics, remove ignition key and make sure all moving parts have come to a complete stop. IMPORTANT If any bolts or nuts are dropped in the machine, be sure to remove them before starting the machine. Remove items from the shredder area by removing the discharge screen. 2.1 INSTALLING DISCHARGE TUBE 1. Remove the skid steer chipper from the shipping pallet. 2.
ASSEMBLY 2.2.2 Mounting the chute support: 1. Make sure the chute is mounted to the roller support weldment. 2. Place the chute support underneath the chute. 3. The side of the chute support with the two mounting holes is orientated towards the chipper base. 2.3 MOUNTING THE FOUR-POSITION VALVE 1. Place the 4 position valve on the chipper chute over the three pre-drilled mounting holes. 2.
3 Section Features & Controls feed roller rate control discharge deflector The feed roller speed is adjustable with a hand crank located below the chipper feed table. Use a slower feed roller speed when feeding large branches into the chipper. Increase the feed roller speed when feeding small branches into the chipper. Turning the crank counter-clockwise decreases the feed roller speed. Turning the crank clockwise increases the feed roller speed.
4 Section Operation 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. chipping OPERATION The chipping operation takes place on the rear of the machine, where hardened steel chipper blades are mounted on a rotating rotor assembly. Material fed into the chipper chute is sliced into small chips and propelled out through a discharge tube. 5.
OPERATION 4.3 install flush face couplers WARNING Hydraulic lines may be under pressure due to testing done at the factory. The skid steer chipper is equipped to attach to flush face couplers (Figure 4.3). The chipper is shipped with -12 sized hydraulic couplers fitted on the hoses. A tie wrap is used to indicate the pressure line. Be sure to connect the hydraulic hoses to the proper ports.
