Operation Note: Determine the left and right sides of the machine from the normal operating position. Adjusting the Discharge Opening Operating Tips The discharge opening is adjustable to increase or decrease air output velocity and volume. Decreasing the discharge opening size will increase the velocity. Warning 1. Loosen the discharge opening deflector mounting screws (Fig. 7). Discharged air has considerable force and could cause injury or loss of footing.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Lubrication Idler Arm Bearing The idler arm bearing (Fig. 8) must be lubricated after every 8 hours of operation with a No. 2 Lithium-based grease. Figure 9 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 (Fig. 10). Use a No. 2 Lithium-based grease.
Adjusting the Blower Belt 3. When the belt stretches, adjust it as follows: A. Loosen the nuts securing the belt tensioner to the blower housing. Make sure belt is properly tensioned to ensure proper operation of the machine and unnecessary wear. Check belt frequently. B. Move the belt tensioner (Fig. 13) down until the idler spring body is extended to a length of 3-1/4 to 3-1/2 in. (83–89 mm) (Fig. 12), then tighten the nuts.
