4 OPERATION

Section

As with any other piece of outdoor 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 on the front of the machine, where hardened steel chipper blades are mounted on a rotating rotor assembly. Material fed into the chipper chute is sliced into small chips and propelled out through a discharge tube.

WARNING

Before operating your machine, be sure you read and understand all safety, controls and operating instructions in this owner's manual and on your machine. Failure to follow these instructions can result

in serious injury or property damage.

WARNING

Move machine to a clear, level area outdoors before starting. Do not operate in the vicinity of bystanders. Make sure cutting chamber is empty before starting.

4.1 STARTING ENGINE

BEFORE ATTEMPTING TO START THIS MACHINE, MAKE SURE THE BELT IS DISENGAGED AND THE HANDLE IS IN THE "START" POSITION.

NEVER ATTEMPT TO START MACHINE WITH THE DRIVE BELT ENGAGED.

1. Check engine oil level before starting.

2. Place the throttle control midway between the SLOW and FAST positions. Place the choke control into the CHOKE position.

3. Place the chipper engagement lever in the START position.

4. Use key switch to start the engine.

5. Move the choke to the RUN position.

● For a cold engine: gradually return the choke to the

OFF position after the engine starts and warms up.

● For a warm engine: use of choke may not be

necessary for restart of a warm engine. If it is needed, return choke to the OFF position once the engine starts.

4.2 OPERATING THE CHIPPER

After the engine has been started and properly allowed to warm to an operating temperature, you can begin operating the chipper. To properly start and operate the chipper, follow the steps below:

1. AFTER engine is warmed and ready for use, move

the throttle control back to approximately 25% of full throttle.

2. When engine is running at approximately 25% of

full throttle, SLOWLY engage belt by using the belt engagement lever.

DO NOT engage the belt with engine running at high RPM.

Engaging belt while engine is running at high

RPM will result in signicant belt squealing and

damage. Engaging belt while engine is running at high

RPM can also damage vital drive components of the chipper.

3. If the chipper engine stalls while engaging the belt, return the engagement handle back to the START position, restart engine, SLIGHTLY increase throttle and attempt engagement again.

4. Once the belt is engaged, SLOWLY increase throttle to 100% or full throttle.

5. ALWAYS run the chipper at 100% or full throttle when chipping material.

12 6 INCH CHIPPER

Page 17

4.3 CHIPPER OPERATION GUIDELINES

OPERATION

WARNING

Read and follow all safety instructions in this manual. Failure to operate the machine in accordance with the safety instructions MAY RESULT IN PERSONAL

INJURY!

The machine chips a variety of materials into a more readily decomposed or handled condition. The following guidelines will help you get started.

1. Gradually increase engine speed until full throttle is achieved. When the controller light is steady green

the engine speed is high enough to begin to chip.

2. ALWAYS run engine at full operating speed before starting to chip material.

3. Engage the hydraulic feed by pushing the forward

button from the Chipping Screen (see Section 4.7 for more details on utilizing the Digital Display Controller).

4. If the chipper rotor slows, the feed roller will stop automatically to process backed up material. Feed material more evenly.

5. If the chipper jams, the feed roller will reverse momentarily to remove the branch. Once the branch is removed, rotate it before reinserting into the chute. Alternately insert and retract the limb or insert continuously at a rate that will not kill the engine.

6. Sharpen the chipping blades periodically. Check the sharpness of the blades every 5-15 hours. Refer to the Service and Maintenance section for sharpening instructions.

7. Limbs fed in to the chipper chute must be 6 inches (15 cm) in diameter or less. Trim side branches that

cannot be bent enough to feed into the chipper chute. Hold small diameter branches together in a bundle and feed in simultaneously.

8. Alternate green or fresh cut material with dry material to lubricate the chipping blades for longer life and better performance. Chipping dead,

dry material will create heat and dull the chipping blades quicker.

9. ALWAYS feed brush from the side of the chipper chute, rather than from the front. Step aside to avoid

being hit by the brush moving into the chipper.

10. ALWAYS place limb, butt end rst, 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.

11. NEVER use the belt engagement to clear a plugged rotor. This may cause belt damage. Refer

to the instructions for clearing a plugged rotor in the Service and Maintenance section.

12. NEVER attempt to clear a plugged rotor or discharge with the engine running. ALWAYS shut engine OFF and remove the spark plug wire before servicing any part of this machine.

13. NEVER attempt to chip pieces of metal, rock, bottles,

cans or other foreign objects.

CAUTION

● Never lean over the chipper chute to push objects

into the cutting device. Use a push stick or brush paddle.

● Never use shovels or forks to feed brush. They

can cause extensive damage if they contact the

blades. In addition, metal pieces can be ejected from the chipper chute and cause serious injury

or death.

● Never feed brush into the chute with your feet.

● Never use hands or feet to clear materials that

build up in the chute.

CAUTION

● Obtain and wear safety glasses at all times when

operating the machine.

● Do not wear loose tting clothing.

● The operator should always wear heavy boots,

gloves, pants and a long-sleeved shirt.

● Use common sense and practice safety to protect

yourself from branches, sharp objects, and other harmful objects.

Page 18

OPERATION

4.4 SLOWING AND STOPPING THE CHIPPER ROTOR AND ENGINE

NEVER disengage the belt as part of the stopping or shut down process. The belt should remain engaged during the entire shutdown process.

Leaving the belt engaged is a vital part of proper shutdown and ensures the rotor stops spinning in

conjunction with the engine shutting o󰀨.

TO PROPERLY SLOW DOWN AND STOP THE ROTOR AND ENGINE

1. With the belt still engaged, slowly move the throttle to the SLOW position with the belt still engaged.

2. Allow the engine to run at slow idle for 30-60 seconds.

3. Stop the engine by moving the throttle to the STOP

position or turning o󰀨 the ignition switch.

4. Allow rotor to come to a complete stop.

5. Once the engine is o󰀨 and the rotor has completely stopped, the belt can be disengaged by moving the belt engagement handle back to the START position.

4.6 CHIPPER FEED CONTROLLER

This machine is equipped with a Digital Display Controller

(DDC). The DDC monitors the chipper rotor RPM and

regulates the feed roller. When chipper rotor RPM drops too low, the feed roller

is stopped automatically to allow the chipper rotor to process material.

When the chipper rotor returns to chipping RPM, the feed roller will automatically reengage.

Try Again Feature: If the feed roller becomes obstructed, the controller will reverse the feed roller momentarily to clear the obstruction. The controller will then engage the feed roller and feed the material again.

This cycle may continue for 10 cycles before staying in the reverse position. Remove or reposition the material manually and activate the forward position.

Remember to sharpen blades when necessary so material will feed smoothly.

NOTE

The rotor will continue to turn for some time after the

engine has been shut o󰀨. Make sure rotor has stopped

completely before inspecting or servicing machine.

4.5 FEED ROLLER SPEED CONTROL

This machine is equipped with a ow control to vary

the speed of the feed roller. This allows the operator to increase the feed speed when processing smaller material and lower the speed when handling material close to the maximum capacity of the machine. It is recommended that operators start using the machine at the lower limits of the speed control and slowly increase the speed, according to the size and hardness of the material being chipped.

While occasional stopping and starting of the feed roller is normal, frequent stopping and starting of the feed roller and/or rapid decreases in chipper rotor RPMs is an indication that the feed speed is too high. Continued operation under such conditions can result in plugging of

the discharge, belt damage, and ine󰀩cient operation. Recommended Procedure: Turn the ow control knob

fully clockwise to bring the feed roller to a stop. Turn the

ow control knob counter clockwise two full turns and begin feeding material into the chipper. Adjust as needed.

The rotor sensor and safety bar sensors must be set to the correct clearance or the chipper will not operate.

Set the clearance to 1/32" (the width of a credit card). The sensor will ash with every rotation of the chipper

rotor when the clearance is set correctly.

4.7 USING THE DIGITAL DISPLAY CONTROLLER

The feed roller FORWARD and REVERSE functions are controlled by the controller. In addition to the feed roller control functions, the controller also provides service reminders, onboard diagnostics, operating instructions, troubleshooting help and language selection.

● Solid Green – The chipping rotor has achieved

su󰀩cient RPM to begin chipping. The feed roller can

now be engaged in the forward direction. The text box below the indicator will display "FORWARD," "REVERSE," or "STOP."

● Solid Red – The knee bar has been activated and the

feed roller is now stopped. The text block below the indicator will display "Hold Knee Bar Reset."

The Knee Bar functions as an emergency stop system for the feed roller to immediately stop the feed roller system. Occasionally, branches or limbs may contact the Knee Bar with enough force to activate the Knee Bar safety circuit. When this occurs the operator will need to reset the Knee Bar safety system with the "Knee Bar Reset" button to continue chipping. The "Knee Bar Reset" button will need to be held for two seconds to reset the system.

Carefully check to be certain the infeed chute and feed roller are clear and that it is safe to continue chipping before resetting the Knee Bar Reset.

● Solid Yellow – There is a fault in the chipper control

system. The text box below the indicator will display "Go to Diagnostic Screen."

The buttons to the left and to the right of the Navigation Button are used to control the feed roller.

The Forward button starts the feed roller turning forward and feeds material into the chipper.

The Reverse button reverses the direction of the feed roller and will push the material back toward the operator.

The Stop button stops the feed roller.

The Knee Bar Reset button resets the controller so Forward and Reverse can be re-engaged after the Knee Bar safety system has been activated. To re-engage the

feed roller safety system after the Knee Bar safety system has been activated, the operator must press and hold the Knee bar Reset button for two seconds.

Any time the Knee Bar safety system is activated, carefully check that the infeed chute and feed roller are clear and it is safe to continue chipping before resetting the Knee Bar safety system.

4. Remove the two bolts that hold the blade to the rotor. The hardware can be reused. Repeat for the remaining blade.

5. The blades have two edges and can be reversed one time before sharpening.

4. Use short grinding times and cool with water or some type of liquid coolant.

5. Remove an equal amount o󰀨 each blade to maintain rotor balance.

6. Small imperfections such as nicks and burrs on

the at side of the blade will not a󰀨ect the chipping

performance of the machine.

7. 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 (see Section 5.4).

5.6 SHARPENING THE BLADES 5.7 INSTALLING THE BLADES

The blades can be ground on a bench grinder or by a professional.

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 chopping blades to

45 degrees (Figure 5.2). Use the blade angles on the

anvil spacing gauge when sharpening the blades to

achieve the proper angle (see Figure 5.3).

3. Be careful when grinding so that the blade does not become overheated and change color. This will remove the heat-treated properties.

1. Install the rotor lock (Section 5.2). The rotor is now

restrained for installing the blades.

2. Place a blade on the rotor and attach using original

hardware. Torque the bolts to 120 ft-lbs. (162 Nm).

Repeat for the remaining blade.

3. Remove rotor lock.

4. Lower the access cover and secure to the chipper housing using two 3/8" retaining bolts.

5.8 SETTING CHIPPER BLADE CLEARANCE

The chipping blades should clear the chipper block located directly under the chipper chute by 1/16 to 1/8".

To adjust the blade clearance, proceed as follows:

1. Remove the two 3/8" retaining bolts securing the access cover to the main frame. Open access cover to allow access to anvil. See Figure 5.4 for anvil location.

2. Loosen the three 1/2" bolts that hold the chipper anvil to the frame.

WARNING

BEFORE INSPECTING OR SERVICING ANY PART OF THIS MACHINE, SHUT OFF POWER SOURCE, DISENGAGE THE

HYDRAULICS, OPEN SHIELD AND MAKE SURE ALL MOVING PARTS HAVE COME TO A COMPLETE STOP.

5.13 HYDRAULIC FEED MAINTENANCE

Hydraulic uid drives the feed roller. Check the uid level daily and ll as needed. The uid and lter should be changed and system cleaned if the uid becomes contaminated with foreign matter (water, dirt, grease, etc.) or if the uid has been subjected to temperatures greater

than the maximum recommended.

The hydraulic pump requires premium hydraulic uids

containing high quality rust, oxidation, and foam inhibitors. These include premium turbine oils, API CD engine oils per SAE J183, M2C33F or G automatic transmission

uids meeting Allison C-3 or Caterpillar TO-2, and certain specialty agricultural tractor uids.

WARNING

Handle pressurized hydraulic uid carefully. Escaping pressurized hydraulic uid may penetrate your skin causing serious injury. This uid may also be hot

enough to burn. Serious infection or reactions can develop if immediate proper medical treatment is not administered.

5.14 CHANGE HYDRAULIC FLUID FILTER

Change the hydraulic oil lter after the rst 50 hours of

operation and every 200 hours thereafter.

To change the hydraulic oil lter:

1. Using an oil lter wrench, turn the lter

counterclockwise.

2. Once the lter becomes loose, turn it out the rest of

the way with your hand.

3. Properly discard old lter.

4. Lube the rubber seal on the new lter with clean

hydraulic oil.

5. Install the lter onto the threaded pipe. Turn with your

hand until the lter is nger tight.

6. Using an oil lter wrench, tighten the lter another 1/2

turn.

7. Check hydraulic oil level and ll if necessary.

In the unlikely event that the oil is completely drained from the hydraulic system, oil must be added and any air bubbles must be purged from the system. To do this:

1. Clean all system components (reservoir, ttings, etc.).

2. Fill the hydraulic reservoir.

3. Start the engine and run at the lowest possible RPM.

4. As you purge air from the unit, the oil level in the reservoir will drop and bubbles may appear in the

uid. Rell the reservoir as necessary.

5. Run the feed roller in both directions for several minutes until any remaining air purges from the unit.

Rell the reservoir as necessary.

6. Shut down the engine, check for and correct any

uid leaks, and check the reservoir level. Add uid

if necessary. The hydraulic pump is now ready for operation.

NOTE

Hydraulic pressure controlled by the relief valve is factory set at 2500 PSI.
