Rotating the discharge chute to the right place, align two of the four bolt holes in the discharge chute disk cover with the two arc wall in the adapter- connector and fix them using two MIO, two washers and two nuts.

FEATURES & CONTROLS SECTION

Understanding how your machine works will help you achieve the best results when using your chipper. The following descriptions define the features and controls of your machine.

DISCHARGE TUBE

The discharge chute can be rotated 360 degree horizontally by moving the bolts on it.

INFEED CHUTE

MODELS: ALL MODELS
Materials to be chipped are fed into the infeed chute, through the infeed rollers, to the chipper blades. On the top of the chute is an infeed roller control bar. The chipper will not feed material if the infeed roller control bar is pressed.

CHIPPER BLADES

The chipper blades chip material that is fed into the chipper chute.

FEED ROLLER CONTROL BAR

To engage the infeed roller move the control bar.

PTO SHAFT

MODEL: WC-8H & M Model
Connects the tractor PTO to the chipper drive shaft. Avoid an angle greater than 15 degrees up or down with the unit is in use.

OPERATION SECTION

As with any other piece of outdoor power equipment, getting the feel for how your machine operates and getting to know the best techniques for particular jobs are important to overall good performance.

CHIPPING OPERATION

The chipping operation takes place inside of the rotor housing, where hardened steel blades are mounted on a rotor assembly. Material fed into the chipper infeed chute is sliced into small chips and propelled out through the discharge chute. The chips can be diverted into a container or onto the ground.

WARNING!
Before operating your machine, be sure you read and understand all safety, control and operating instructions in this Owner/Operators manual and on your machine. Failure to follow these instructions can result in serious injury or property damage.

STARTING TRACTORS

MODELS: WC-8H & M MODELS

1. CONNECTING THE PTO SHAFT
   Move the machine to a clear, level area outdoors before starting. Do not operate in the vicinity of bystanders.
   Make sure the cutting chamber is empty before starting.
   Connect the PTO shaft between the chipper and the tractor. The minimum & maximum telescoping on the PTO shaft is 26″ to 32″.

2. Start the tractor engine and engage the tractor PTO.

3. Increase the engine speed to the rated PTO (540RPM) position.

STOPPING TRACTORS

MODELS: WC-8h & M MODELS
1. Move the tractor throttle to the SLOW position.
2. Disengage the PTO lever and shut off the tractor engine.
3. Allow machine to come to a complete stop.

CHIPPING GUIDE

The chipper chips a variety of materials into a more readily decomposed or handled condition. The following guidelines can help you get started.
Run unit at full operating speed before starting to chip material.
These machines are most effective when chipping material 0-8″ in diameter.
Trim those lateral branches that cannot be bent enough to feed into the chipper chute. Hold small diameter branches together in a bundle and feed in simultaneously.
Exclude pieces of metal, rocks, bottles, cans, and other foreign objects when feeding chip able material into the machine.
Do not lean over the chipper chute to push objects into the cutting device. Use a push stick or brush paddle.
Place limb, butt end first, into the chipper chute until it contacts the chipper blades. The actual feed rate of the limb into the chipper will depend on the type of material fed and sharpness of the cutting blades.
Stop the material feeding and allow the engine to recover if the engine slows to where it may stall.
Alternately insert and retract the limb or insert continuously at a rate that will not kill the engine.
Chipping dead, dry material will create heat and dull the chipping blades eventually.
Alternate green material with dry material can lubricate the chipping blades for longer life and better performance.
The chipping blades will become dull and will require periodic sharpening. Refer to the Service and Maintenance section for sharpening instructions.

SERVICE & MAINTENANCE

MAINTENANCE SCHEDULE

The items listed in the service and maintenance schedule are to be checked, and if necessary, corrective action taken. This schedule is designed for units operating under normal conditions. If the unit is operating in advance or severe usage condition it may be necessary for the items to be checked and serviced more frequently.

WARNING!
BEFORE INSPECTING OR SERVICING ANY PART OF THIS MACHINE, SHUT OFF POWER SOURCE, AND MAKE SURE ALL MOVING PARTS HAVE COME TO A COMPLETE STOP.

CHIPPER BLADES

WARNING: Chipping blades are sharp! Use caution when working on machine to avoid injury.
The chipping blades will eventually become dull, making chipping difficult and adding extra strain on the machine. Poor chipping performance is usually a result of dull chipping blades. It is recommended that the blades be sharpened every 5-15 hours or if your chipper’s performance has decreased. Check for the following symptoms and
sharpen the blades if needed.
Severe vibration when feeding material into the chipper.
Small diameter branches do not self-feed.
Chips discharge unevenly or have larger ends, especially when chipping green branches.
Before you sharpen the chipping blades, check for permanent damage. Replace the blade when needed.

1. There are cracks, broken comers or nicks.
2. The base of the cutting edge is worn or has been re-sharpened

REPLACING AND SHARPENING THE KIVES (Blades)

Removing the Knives

1. Remove the rotor cover from the chipper housing by loosing and removing the two MIO bolts.
2. Remove the four bolts on the back side access of disk cover.
3. Rotate the disk so that the bolts holding the chipper blades are accessible.
4. Install the chipper blades and cover carefully.
5. Inspect blades to see if cracks or nicks are visible. If cracks are present, replace the blades. If nicks cannot be removed by sharpening blade, replace the blade.

SHARPENING THE BLADES

1. Never sharpen or grind the mounting surfaces of the blades. This will cause the edge to roll and the blade will be damaged, resulting in poor chipping performance.
2. Regrind the angled edge of the chipping blades to 30~32 degrees (Figure 5.1).
3. The blades can be ground on a bench grinder or by a professional.
4.  Make sure some type of fixture is used to correctly hold the blade at the proper angle.
5. Be careful when grinding so that the blade does not become overheated and change color. This will remove the heat treated properties.
6. Use short grinding times and cool with water or some type of liquid coolant.
7. Remove an equal amount off each blade to maintain rotor balance.
8. Small imperfections such as nicks and burrs on the flat side of the blade will not affect the chipping performance of the machine.
9. For blades that have been repeatedly sharpened, ensure that the sharpened surface extends past the chipping slot opening. If it does not extend past the opening, the blades should be replaced.

INSTALLING THE BLADES

1. Place a blade on the disk and attach with three MIO Countersunk head hex bolts and three MIO locknuts.
Torque the bolt to 75 foot-pounds. Repeat for the remaining blades. The chipping blades should clear to the disk surface, by least 2mm. To adjust (increase) the blade clearance,
l-3mm aluminum sheet can be placed under blades to the size of the debris. But the chipping blades should clear to the chipping anvil, located directly under the chipper chute, by least 1.5mm meanwhile (Figure 5.2).
It is important to ensure that the minimum gap between the chipping anvil and ALL chipping blades is 1.5mm. Failure to do so can result in the chipping blades striking the chipping, causing serious injury or death.

Figure 5.2

2. Close the Rotor cover.

DRIVE BELT ADJUSTMENT

Check the condition of the drive belt(s) annually or after every 25 hours of operation, whichever comes first. Replace a cracked, frayed, worn or stretched drive belt. Only replace drive belt with original banded type belt. Do not use single type belts. To adjust the drive belt(s), proceed as follows:

WC-8H & M-MODELS
The main drive belts on the chipper need to be tight. To tighten these belts may by tightening the four adjustable bolts under the bottom of the power- input-shaft bearing support. Keep the power-input-shaft parallel with the main shaft. Torque the bottom bolts 80 feet pounds.

WC-8H & M-MODELS
The infeed roller drive belt can be adjusted by first loosening the four bolts that hold the worm gear box to the base, then moving the gear box away from the adjustable bolt and re-torques the bolts to 40 ft. pounds.

GREASING THE BEARINGS AND PIVOTS

Mounted bearings are pre-lubricated at our factory and are ready for operation.

RELUBRICATION : Relubrication of bearings is determined by operating conditions and environment. Relubricate standard bearings with a LITHIUM based grease.

GREASING INTERVALS : Bearings in extreme environments will require more frequent greasing intervals. Care should be taken when greasing bearings to avoid overfilling.

Overfilling can lead to excessive heat and or unseating of the seals. Grease should be introduced in small increments and under light pressure. Whenever possible, the bearing should be rotated slowly while grease is being added to ensure equal distribution throughout the raceways.
