Piovan Group Shredder SFH

- Replace any damaged parts as quickly as possible. This will reduce possibility of more severe damages

- Check for loose screws, bolts, hydraulic connections, etc. on a regular 50 hour operational interval. Correct any problems that are discovered immediately

- Check hydraulic fluid level daily. Check other component functions as outlined in Chapter 4

- Rotate or replace indexable cutters located on rotor whenever cutting results are poor. Torque bolts to proper torque according to torque value found in the appendix. Rotate rotor by hand to ensure proper clearance to counter knife before start-up

- Replace/rotate/sharpen counter-knives whenever cutting results are poor. Rotate rotor by hand and adjust counter-knives to proper clearance before applying power. Be sure counter-knife retaining bolts are tightened to proper torque according to torque value found in the appendix. Refer to adjustment information for proper alignment

- To insure proper cooling of motors and machine components make sure machine is free of dust at all times. Clean on a regular basis

- Check on daily basis for unrestricted air flow on hydraulic oil cooler

- If machine has air cooler on hydraulic package, remove front cover and clean with compressed air from back side of cooler to remove foreign material, whenever conditions indicate need

- Follow all lock out / tag out procedures while maintaining, servicing or cleaning the shredder

- If rotor removal is required, you should consult Conair Service (800-458-1960) for resetting the bearings on the rotor

- Pillow Block Bearings should be lubricated on a regular basis. The recommended cycle to grease these bearings is every 50 hours of operation. Do not over grease. Shell Albida 220 Synthetic Lithium Complex grease or equivalent should be used (page 41). (Refer to manufacturer’s manual provided);

- The oil level in the gearbox should be checked on a regular basis

- The oil level in the fluid coupling should be checked on a regular basis. Fluid coupling oil should be checked after every 6 months of operation (fluid should be cold while performing check)

- If the fusible plug blows at regular intervals in normal service, check the following listed possible causes for correction. High oil operating temperature can be caused by the following:

2 Absorbed power is higher than the motor rated power

6 Inadequate air ventilation to allow cooling of the coupling. If coupling is operated in a restricted space, adequate ventilation apertures should be provided;

- Inspect bushing for fatigue cracks in rubber cushion area. Inspect bushing pin bore for excessive movement between diameter and bore of bushing. The bushings are pressed into the torque arm assembly; therefore it is recommended to replace torque arm assembly and adjusting pin if bushing replacement is necessary

- Inspect Ram Wipers. Replacement will be necessary when 5/8" to 3/4" of wear is present (page 47)

- Inspect for wear on monthly basis. They are generally considered worn when approximately 1/8” from original specs and should be replaced (page 48)

- The hydraulics power system employs a high quality return oil filter (page 49). The filter has an indicator that changes color when it is time to be changed. Check filter every 30 days. The hydraulic fluid should last indefinitely unless it suffers severe overheating

- Inspect breather filter and replace when required. If machine is operated in extreme temperature conditions, adding an oil heater or oil cooler may be required

- The oil level in the tank should be checked on a regular basis. Refill hydraulic oil as necessary with this oil or equivalent. Do not overfill the hydraulic tank with oil. - The hydraulic cylinder requires lubrication to clevis pins. Grease fittings located on clevis eye require lubrication with grease once monthly. Visually inspect following items frequently:

1 Inspect all lines and fittings for leakage

2 Inspect rod end of cylinder for leakage at packing cap seals

- The rotor carries a limited lifetime warranty; - it is the user’s responsibility to maintain the rotor and components secured preventing excessive wear or neglect. The rotor surface should be routinely inspected for gouges or indentations caused by tramped metal impacts

- The rotary seals bolted to the ends of the rotor should be maintained with bolts tightened, locking tabs secured, and clearance from the fixed rotary seal

- The roller bearings at each end of the rotor should be inspected regularly and maintained accordingly

- The gearbox mounted on the drive-side of the machine should be maintained accordingly and hollow shaft mounting system should be tight and locking tabs secured

- Cutters and tool holders should be maintained and replaced as necessary

- The rotor should never be allowed to run with tool holders and cutters missing from any intended pocket

- Whenever cutters require replacement due to wear or damage the following procedure must be followed

- Cutters are attached to the rotor shaft using a hex screw and a ribbed lock washer - It is advised to rotate or replace all cutters at the same time. It is advised to replace mounting bolt and ribbed washer at the time of cutter replacement

- Whenever counter knives require adjustment or replacement due to wear or damage the following procedure must be followed. Counter knives are attached to the anvil using multiple hex screws. Counter knives may be rotated once and then sharpened using a surface grinder, grind .030” or less to sharpen the knives. It is advised to rotate or replace all counter knives at the same time. It is advised to replace mounting bolts at the time of counter knife replacement (page 40)
