Safety • Using the machine demands attention. To prevent loss of control: – Operate only in daylight or when there is good artificial light. – Drive slowly and watch for holes or other hidden hazards. – Do not drive close to a sand trap, ditch, creek, or other hazard. – Reduce your speed when making sharp turns and when turning on hillsides. – Avoid sudden starts and stops. – Before backing up, look to the rear and ensure that no one is behind the machine.
Check the fan shaft bearing mounting bolts and nuts frequently to be sure that they are tightened to specification. • If the engine must be running to perform a maintenance adjustment, keep hands, feet, clothing, and other parts of the body away from the fan and other moving parts. • Make sure that all hydraulic line connectors are tight and all hydraulic hoses and lines are in good condition before applying pressure to the system. • Do not overspeed the engine by changing the governor settings.

Operation 2. Lower the blower using the traction unit lift mechanism. Note: Determine the left and right sides of the machine from the normal operating position. 3. Engage the PTO while the engine is at idle speed. Transporting the Blower 5. Practice blowing material. It is advisable to blow the same direction the wind is blowing to prevent material from blowing back into the cleared area. 4. Increase the PTO speed to 1800 RPM. 1. Start the traction unit and run it at a low RPM. 2.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Lubrication Idler Arm Bearing The idler arm bearing (Figure 9) must be lubricated after every 8 hours of operation with a No. 2 Lithium-based grease. Figure 10 Drive Shaft and Guards Under normal conditions, grease the (2) drive shaft fittings after every 100 hours of use and the guards after every 8 hours of operation (Figure 11). Use a No. 2 Lithium-based grease.
Figure 12 1. Belt guard 2. A new belt is properly tensioned when the idler spring body is extended to a length of 3-1/4 to 3-1/2 in. (83-89 mm) (Figure 13). Figure 14 1. Belt tensioner 2. Belt tensioner notch Adjusting the Blower Belt Make sure belt is properly tensioned to ensure proper operation of the machine and unnecessary wear. Check belt frequently. Note: Check/adjust the blower belt tension after the first 20 hours of operation. Figure 13 1. Idler spring 2. 3-1/4 to 3-1/2 in. (83-89 mm) 1.
Storage 1. Thoroughly clean the blower. The fan housing should be free of dirt, leaves, and debris. 2. Lubricate all grease fittings. Wipe off any excess lubricant. 3. Place a light coat of grease on the splines of the PTO adapter. Figure 16 1. Idler spring 4. Tighten all fasteners. 2. 3-1/4 to 3-1/2 in. (83-89 mm) 3. When the belt stretches, adjust it as follows: • Loosen the nuts securing the belt tensioner to the blower housing.
Troubleshooting Problem Possible Cause Corrective Action The fan quits turning. 1. The bolt on the PTO adapter may be sheared. 1. Replace the bolt. There is excessive vibration. 1. The bearing on the fan shaft is damaged. 1. Replace the bearings. 2. Material is built up on the fan blades. 3. The RPM of the PTO shaft is too fast. 2. Clean out any build up on the inside of the housing. 3. Reduce the PTO speed to 540 RPM. 1. The air slots are clogged with debris. 1.
