Safety – Ensure the appropriate rear weight kits are added to rear of traction unit when the broom is installed. Refer to Install Rear Weight on page 9. Hazard control and accident prevention are dependent upon the awareness, concern, and proper training of the personnel involved in the operation, transport, maintenance, and storage of the machine. Improper use or maintenance of the machine can result in injury or death.
• If the Rotary Hydraulic Broom begins to vibrate abnormally, stop immediately. Shut off the traction unit engine.

Setup General 4. Route the power wires through the steering column and frame to the instrument panel and attach the negative wire (black) to the common ground terminal and the positive wire (red) to the rear terminal of the fuel gauge. Reinstall cover. Refer to illustrated parts list for details of parts used in assembling and installing the Rotary Hydraulic Broom. Install the Push Arm Note: Determine the left and right sides of the machine from the normal operating position. Note: Ball Joint Mount L.
The traction unit or broom may need to be moved slightly to allow the PTO shafts to be coupled. Note: The PTO shafts will only align and insert in one position. 5. Have a helper carefully push down on left hand push arm until holes in ball joint mount are in line with holes in broom mount. Immediately slide 4 x 4 in. block of wood between top of push arm and underside of chassis. Warning Make sure wooden block does not slip out accidentally. Figure 2 1.
Install Rear Weight To comply with CEN standard EN 836:1997, ISO standard 5395:1990 and ANSI/OPEI B71.4–1999 Standard, rear weight must be added to rear of traction unit. Use chart below to determine weight requirements. Order parts from your local Authorized Toro Distributor.

Before Operating Operating Position Adjust Brush Down Pressure Improper downward pressure can decrease brush life up to 95% (depending on the incorrect amount of pressure). A brush sweeps with the tips of its bristles. When too much down pressure is applied, the brush is no longer using it’s tips; the brush is now working with the sides of the bristles. This limits the flicking action of the bristles and limits it’s sweeping effectiveness.
Operating Instructions Ground Speed Bulldozing produces a side thrust and excessive stress on the broom. While operating under the plow effect, the bristles are flexed against the steel ring which holds them and, eventually, this flexing will break the bristles from the ring. Note: Determine the left and right sides of the machine from the normal operating position. Warning Curb Climbing and Trailer Loading Thrown debris has considerable force and could cause injury.
Maintenance mount. Now the helper can carefully allow the push arm to move upward, which will gradually release the 100 pounds of spring load. Caution 5. Have a helper carefully push down on left push arm while you remove the capscrews, flat washers and flange nuts securing the ball joint mount to the broom mount. Now the helper can carefully allow the push arm to move upward, which will gradually release the 150 pounds of spring load.
Servicing Castor Fork Bushings 8. Reinstall brush retaining plate. 9. Reinstall bearing housing, hydraulic motor mount and guard. After many hours of operation, the bushings pressed into the top and bottom of the frame bracket will wear. To check the bushings, move castor fork fore and aft and from side to side. If castor spindle is loose in the bushings, bushings are worn and must be replaced.
Servicing Castor Wheel And Bearing The castor wheel rotates on a high–quality sealed roller bearing and is supported by a spanner bushing. Even after many hours of use the bearing wear will be minimal. A wobbly castor wheel usually indicates a worn bearing. 1. Remove locknut from capscrew holding castor wheel assembly in castor fork. Grasp castor wheel and slide capscrew out of fork. 2. Remove outer bearing from wheel hub and allow bearing spacer to fall out.
