Features of Virnig Mfg. Inc. Snow Blower include:

• Two stage design featuring an 18” diameter paddle style auger to better break up hard, compacted snow and 24” diameter 4 blade fan to provide more efficient throwing of snow.

• Hydraulic manifold with electric solenoids controls the spout rotation of 270° and deflection using either the machines electrical controls or a Two Switch Control Box to be located inside the cab of the machine.

• Replaceable 5/8” x 8” double bevel reversible cutting edge with adjustable, replaceable skid shoes.

• Direct drive fan and auger motors eliminates the need for chains and gearboxes.

• Large 28” cut height allows clearing of deep snow.

• Auger can operate in reverse to expel any lodged objects, fan spins in throwing direction only.

• Machine specific hydraulic package to best utilize machine hydraulics.

• Recommended for loaders with an operating capacity greater than 1500 lb.

Initial Use

• Read and understand all warning information in this manual before operating this attachment.

• Check that quick-tach on frame fits onto loader properly. Pins must engage through 3/8” plates at bottom of quick-tach.

• Slowly roll back attachment. Make sure there is no interference between attachment and loader.

• Connect hydraulic hoses and electrical connections, making sure hoses and electrical wires do not pinch during roll back.

• After connecting hydraulic hoses and electrical connections, engage the machines hydraulics using the machines detent position. If the snow blower fan is not spinning, the couplers on the lead hoses need to be switched to match the machines detent position. (The fan should spin clockwise when looking at the front of the snow blower and the auger should spin counter-clockwise when looking at the left side of the snow blower, relative to the seat.)

• If the snow blower is supplied with an electrical plug (either 8 or 14 pin) to utilize the machines electrical controls, with the snow blower running, determine which machine switches control the rotate and deflector functions.

Initial Use (cont.)

• If the snow blower is supplied with a Two Switch Control Box that plugs into the machines 12 volt power outlet (a 12 volt power outlet that connects to the machines battery is available if the machine does not have a dedicated power outlet), with the Control Box mounted in the machines cab so that the wires are coming out of the bottom of the box, the lower switch is used to control the rotation of the spout and the upper switch is used to control the angle of the spout deflector. Locate Control Box in the cab in a position that allows easy access to the switches.

• Using either the machines electrical controls or the Control Box, with the snow blower auger and fan spinning, cycle both the rotation motor and the deflector cylinder several times to make sure they are working properly.

• If blowing snow off of a concrete or paved surface, the skids can be adjusted even with or up to ½” above or below the cutting edge depending on desired results. If blowing off of dirt or gravel surfaces, the skids should be adjusted approximately 1” below the cutting edge. Make sure both skids are adjusted evenly.

• Never exceed the maximum attachment operating pressure of 4000 psi.

Operation

• Always follow safety and operating information in this manual.

• Always follow all safety and operating instructions of the loader.

• Never remove material deflectors or warning labels.

• Never operate a Snow Blower unless you have been properly trained.

• Make sure all safety labels are in place, look in this manual for their locations.

• Stay alert for any hazards that may be located in the area being blown. Unseen hazards could result in attachment or machine breakage, as well as possible injury to operator or bystanders, or damage to surroundings. If a hazard is struck, immediately shut down snow blower and inspect for damage. Repair as needed.

• Keep bystanders back 100 feet. Do not blow snow towards people as injury or death may occur, or towards buildings, etc. that may be damaged by flying debris.

• Always relieve pressure before connecting or disconnecting hydraulic hoses.

• Clean any debris from attachment. Pay special attention to any debris in quick-tach area before hooking up attachment.

Operation (cont.)

• Before beginning to blow snow, engage the machines hydraulics and operate the deflector cylinder and the chute rotate motor to make sure they are free to operate. If frozen, loosen before proceeding.

• Engage and disengage the Snow Blower hydraulics at low engine speeds. This will help prolong the life of the hydraulic components.

• Do not use the snow blower as a snow “pusher”. Slow down and allow the auger and fan to collect and throw the snow.

• If the snow blower spout should become plugged, do not use your hands or feet to unplug the spout. Stop hydraulic flow to the snow blower, shut machine off and relieve hydraulic pressure. Use a wooden stick to unplug the snow blower.

• If an object should become lodged in the snow blowers auger, reverse the machines hydraulic flow. This should expel the lodged object from the snow blower. If this does not work, disengage the machines hydraulics, shut machine off and relieve the pressure in the hoses. Disconnect the hoses from the machine and plug them together. This should allow the auger to move freely. Remove lodged object, inspect for any damage and repair if needed. Reconnect couplers to machine and resume operation.

• If an object should become lodged in the snow blowers fan, disengage the machines hydraulics, shut machine off and relieve the pressure in the hoses. Disconnect the hoses from the machine and plug them together. This should allow the fan to move freely. Remove lodged object, inspect for any damage and repair if needed. Reconnect couplers to machine and resume operation.

• When blowing snow where you can discharge snow on both sides of your path, start by going down the center of the path and working outwards.

• When blowing snow where you can discharge in one direction only, start at the furthest distance from the discharge area and work toward the discharge area.

• Heavy wet snow will require more power to blow than lighter snow. Adjust the machine travel speed accordingly to provide the most efficient blowing of snow.

• Whenever possible, blow snow with the wind.

• The auger relief valve (Port SQ on the manifold) is preset at the factory to provide the overall best system performance. This valve can be adjusted depending on the conditions at the time. Turning the valve in increases power to the auger and decreases power to the fan while turning the valve out decrease power to the auger and increases power to the fan. Do not adjust unless necessary.

Maintenance *Before each use and after every 10 hours of operation

• Grease bearing (1 fitting).

• Apply thin layer of grease to top and bottom of spout ring (see Item #40). This will allow the spout to rotate more freely.

• Make sure all safety labels are in place, look in this manual for locations.

• Check for loose, worn, or missing parts, repair or replace as needed.

• Remove any foreign debris such as string, wire, etc. that may have wrapped around the auger and/or fan.

• Inspect motors, manifold, hydraulic fittings, and hoses for leaks and damage. Replace as needed. Make sure machine is shut off and hydraulic pressure is relieved before checking for leaks. Never use hands to check for high pressure hydraulic leaks.

• The main pressure relief valve (Port RV1 on the manifold) and the rotate motor/deflector cylinder relief valve (Port RV2 on the manifold) require no maintenance. The valves are pre-set and require no adjustment. Changing settings may cause damage to the motors and/or poor system performance. Please call Virnig Mfg. Inc. with any questions or problems regarding these pressure relief valves.

• Contact your dealer for any required replacement parts.
