  • Page 43: Infeed Roller Control

    WC68 Operator’s Manual 3. INFEED ROLLER CONTROL The valve that controls the wood chipper’s infeed roller speed is located to the right of the infeed chute. Rotating the valve arm as shown in the pictures below will increase or decrease the roller speed without load and will create a pulsating action once loaded with a branch.
  • Page 44 WC68 Operator’s Manual The infeed roller can be set to three (3) different rotation settings—forward, neutral and reverse —by pushing or pulling the red control arm. The forward position pulls branches into the wood chipper; neutral stops the roller from rotating; and reverse pushes the branches back out the wood chipper towards the operator.

    WC68 Operator’s Manual 4. DISCHARGE CHUTE To rotate the discharge chute, push down on the spring-loaded locking pin all the way and twist it 90° to temporarily lock it in the open position. The discharge chute is now free to rotate a full 360°.

  • Page 46: Chipping

    WC68 Operator’s Manual 5. CHIPPING Keep your face and body away from the feed opening. Do not over reach. Keep proper balance and footing at all times. The wood chipper is designed to chip a variety of materials into a more readily decomposing or handled condition. The following guidelines can be used to help you get started.

  • Page 47: Maintenance

    MAINTENANCE REPLACING BLADES Follow these steps when replacing blades. The WC68 wood chipper uses four (4) reversible hardened steel blades. Each blade is 8.62 X 2.72 X 5/16” [219 X 69 X 8 mm] in size. 1. If installed, disconnect the PTO shaft from the tractor for safety.
  • Page 48 WC68 Operator’s Manual 4. Remove the four (4) M10 X 35 mm flat head bolts and M10 lock nuts that fasten the blade to the flywheel using a 6 mm hex key on the bolts and a 17 mm socket/wrench on the lock nuts.

  • Page 49: Blade Sharpening

    WC68 Operator’s Manual BLADE SHARPENING The wood chipper blades will dull, making chipping difficult and cause your tractor to labour. It is recommended to sharpen the blades every 25-50 hours of operation. The WC68 wood chipper uses four (4) hardened steel blades. The blades are reversible and can be sharpened on both sides.

  • Page 50: Setting The Bed Plate Gap

    WC68 Operator’s Manual SETTING THE BED PLATE GAP The bed plate (also known as the anvil plate) is located on the left side of the flywheel housing (when facing the infeed chute). For ideal chipping performance, use the bed plate gap tool to set the gap between the bed plate and the blades.
  • Page 51 WC68 Operator’s Manual 3. Remove the two (2) M8 X 10 mm hex bolts securing the bed plate inspection door located on the right-side of the lower indeed housing. With the bed plate inspection door removed, a clear view of the bed plate and its relationship to the blades can be seen.
  • Page 52 WC68 Operator’s Manual 5. Loosen the three (3) M10 X 25 mm hex bolts securing the bed plate to the lower flywheel housing so the bed plate is free to slide in and out. This movement will increase or decrease the gap between the bed plate and the cutting edge of the blade.

  • Page 54: Replacing The Hydraulic Pump Belt

    WC68 Operator’s Manual REPLACING THE HYDRAULIC PUMP BELT Check the condition and tension of the hydraulic pump belt after every 30 hours of operation. If the infeed roller is not rotating, or it is rotating slowly, the belt could be slipping. A squealing noise may also be heard.

  • Page 55: Adjusting The Control Arm

    WC68 Operator’s Manual ADJUSTING THE CONTROL ARM If the movement of the red control arm feels too stiff or too loose, or if it falls into neutral or reverse unexpectedly, it can be adjusted via the directional control valve. Unscrew the plastic cap from the back of the directional control valve (located under the infeed chute), exposing the jam nut and set screw.

  • Page 56: Greasing

    WC68 Operator’s Manual GREASING BEARINGS & OUTPUT SHAFT The wood chipper has three (3) grease points with Zerk fittings: two (2) flywheel bearings and one (1) infeed roller bearing. Check each grease point prior to use and add grease as needed.
