WARRANTY LABOR: Any labor subject to warranty must be authorized by Buhler Manufacturing. The labor rate for replacing defective parts, where applicable, will be credited at a rate determined by the Company, Buhler Manufacturing. IMPORTANT FACTS: Buckets and Bucket Tines Carry No Warranty Bent Spears Carry No Warranty Snowblower Fan Shafts Carry No Warranty Mower Blades Carry No Warranty Portable Auger Parts Have Two (2) Year Warranty 1 Commercial Snowblower CAUTION 1. Always review operator’s manual before starting new machine. 2. Do not let inexperienced operators or children run this equipment. 3. Never service or clean unit while it is running. 4. Do not remove shields. 5. Stay clear of augers. 6. Stay clear of discharge chute. Rocks can be picked up and thrown. 7. Do not operate in the fully raised position. 8. Relieve pressure on hydraulic system before repairing or adjusting. 9. Wear hand and eye protection when looking for hydraulic leaks. Use cardboard to look for leaks. 10. The quick tach must be securely locked in place before using snowblower. 11. Poor judgment results in accidents. Always be careful. 12. Remember a careful operator is the best insurance. THIS SYMBOL MEANS STAY ALERT! WATCH FOR IT! 2 Commercial Snowblower SNOWBLOWERS This manual is for both Commercial Hydraulic Snowblowers and Commercial PTO Drive Snowblowers. The hydraulic models come in 60”, 74” and 84” widths. The PTO drive model is only available in an 84” width. Hydraulic models come with four different motor series. Hydraulic output on the equipment running the Snowblower must match the requirement for each motor series for the Snowblower to work. The hitch is a skid steer fixed type of quick hitch. The PTO drive model runs at 540 rpm. It is supplied with category 2 hitch pins. There is a shear bolt on the auger and two on the PTO shaft to protect the machine from damage if a large object is picked up. All Snowblowers come with a hydraulic chute control as standard. 3 Commercial Snowblower Commercial Snowblower DECALS 4 Commercial Snowblower Commercial Snowblower DECALS – cont’d. #1 #4 #2 #3 5 Commercial Snowblower OPERATING INSTRUCTIONS 1. HYDRAULIC DRIVE: All snowblower hydraulic blocks are set at the factory for a 2800 - 3000 psi system. Refer to the section on the hydraulic control block if your system does not fall into this range. 2. ALL: Depth of the cut can be partially controlled by tilting the snowblower forward or backward. 3. PTO DRIVE: Adjust the top link of the tractor hitch so the snowblower is just slightly CAUTION tilted back when resting on the ground. Excessive backward tilt may cause the “U” joints to flutter resulting in PTO shear bolt failure. 4. PTO DRIVE: The inside holes on the hitch are spaced to fit a category 2 quick hitch using the pins supplied. The hitch will also fit category 2 three point arms or category 3 if you add bushings. 5. PTO DRIVE: Adjust the lower link sway chains or blocks on the tractor to restrict movement of the blower when operating. 6. ALL: All snowblowers have a hydraulic control spout and spout deflector. Refer to the hydraulic control block section. The pressure to the chute control is regulated by the two modulating elements (#14a and #14b). Each controls the hydraulic pressure in one direction. They are set at the factory to about 2 . turns. If the pressure is too low, the chute won’t turn. If the pressure is too high you could damage the teeth on the spout control ring. To adjust the pressure, you loosen the lock nut on the modulating valve and back off the adjusting screw till the screw turns freely by hand. Turn the screw in till you feel it making contact and turn in 2 . turns. Start with this setting to do any fine adjustment if necessary. Pressure should not go over 1000 psi. The deflector cylinder pressure is regulated by modulating element (#14a). It is set at the factory to about 2 turns. If pressure is too low it will not operate. Excess heat will be generated if it is set too high. Adjust if necessary as per previous paragraph. Operating pressure should be about 700 psi. 7. ALL: Run the snowblower at low rpm to check operation before blowing snow. 8. PTO DRIVE: The blower has two shear bolts to protect the tractor and blower in case a large object enters the blower. PTO shear bolt – two 5/16” x 1” (grade 8); auger shear bolt – 5/16” x 1 .” (grade 5). Shear bolts should be fastened with a lock nut or two jam nuts. These bolts must be tight to prevent wear of the bolts and bolt holes. 9. PTO DRIVE: Never run PTO at over 600 rpm. 6 Commercial Snowblower OPERATING INSTRUCTIONS – cont’d. 10.ALL: Chain tension on auger chain should be set at 3/8” to 1/2” slack. 11.LUBRICATION: a) ALL: The gear teeth on the chute control should be periodically lubricated with gun grease. b) PTO DRIVE: PTO shaft universal joints and square shaft slide should be periodically lubricated with a grease gun. c) ALL: Regularly oiling the chain will significantly increase the life of the c...
