Page 8 Table of Contents START UP & PROPELLING CAUTION: OPERATOR MUST BE SEATED WITH SEAT BELT PROPERLY SECURED WHILE ENGINE IS RUNNING. This model of broom is hydrostatically driven. Motion is achieved by depressing the foot pedal on the floor board to the right of center. Letting the foot pedal up will result in a braking action caused by the hydraulic system.
Page 9 The speed at which this machine is towed depends on road conditions and the personal judgement of the individual in charge. Broce Manufacturing Co. will not be responsible for neglect or poor judgement at anytime during machine operation and/or towing of the machine.
Page 10 Table of Contents OPERATION OF THE SWEEPING CORE All functions of the sweeping core are hydraulically operated. Two control valve handles are mounted to the right of the operator’s seat for controlling these functions. The Joystick controls the core height up down and the right and left angle of Broom.
Page 11 Table of Contents SWEEPING TIPS If the broom starts to hop or bounce, the propelling speed is too high. Slow the machine down, but maintain high engine speed. This will allow you to do a good job on the first pass and you will not need to go over it again.
Page 12 More down pressure does not give a result of better sweeping. The broom gets its sweeping action by the flicking action of the bristles. Broce Brooms are equipped with a float detent control valve. This function should be used as often as possible for optimum sweeping and longer brush life.

Page 22 Table of Contents LUBRICATION AND MAINTENANCE 1. Grease two steering shaft bearings at the front of the machine every day. The front wheel bearings should be cleaned and packed every six months. 3. The tires on the front and rear of the machine should be kept at 32 psi and should be checked on a daily basis.
Page 23 Table of Contents BRAKE INSPECTION AND SERVICE This machine is equipped with dynamic hydraulic braking, conventional hydraulic brakes and a mechanical Parking Brake. The dynamic hydraulic braking will be in operation any time that the engine is running. When the foot pedal is released, the hydraulic system provides enough braking action that the conventional foot pedal brake should not have to be used.
Page 24 Table of Contents ENGINE The normal engine operation and maintenance procedures are covered in a separate manual, which is furnished by the engine manufacturer. We do suggest, however, due to the dusty conditions in which these machines operate, that engine fan inspection and replacement should be accomplished more frequently than the engine manufacturer may suggest.
