1.1 sAfETY ALERT sYMboL

The Owner/Operator's manual uses this symbol to alert you of potential hazards. Whenever you see this symbol, read and obey the safety message that follows it. Failure to obey the safety message could result in personal injury, death or property damage.

cAuTIoN

Indicates an imminently hazardous situation that, if not avoided, will result in death or serious injury.

WARNINg

Indicates a potentially hazardous situation that, if not avoided, could result in death or serious injury.

DANgER

Indicates a potentially hazardous situation that, if not avoided, may result in minor or moderate injury.

1.2 EMIssIoN INfoRMATIoN

WARNINg To ALL cALIfoRNIA AND oThER sTATEs opERATINg ouTDooR poWER EQuIpMENT

under California Law and under the laws of several other states, you are not permitted to operate an internal combustion engine using hydrocarbon fuels on any forest covered, brush covered

or grass covered land or on land covered with grain, hay or other ammable agricultural crops,

without an engine spark arrester in continuous effective working order. The engine on your power equipment, like most outdoor power equipment, is an internal com-

bustion engine that burns gasoline (a hydrocarbon fuel). Therefore, your power equipment must

be equipped with a spark arrester mufer in continuous effective working order. The spark ar-

rester must be attached to the engine exhaust system in such a manner that ames or heat from the system will not ignite ammable material.

Failure of the owner/operator of the equipment to comply with this regulation is a misdemeanor under California law and may also be

a violation of other state and/or federal regulations, laws, ordinances, or codes. Contact your local re marshal or forest service for specic information about which regulations apply in your area.

The standard mufer installed on the engine is not equipped with a spark arrester. One must be added before using this

machine in an area where a spark arrester is required by law. Contact the local authorities if these laws apply to you. See your

authorized engine dealer for spark arrester options.

2.5 chEckINg/ADDINg hYDRAuLIc fLuID

ASSEMBLY

Hydraulic uid drives the feed roller. The hydraulic pump is direct or belt driven from the engine or disk rotor.

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 u-

ids. If system has no oil, follow this startup procedure:

Clean all system components (reservoir, fittings, etc.) before

starting the hydraulic pump. After filtering the hydraulic fluid, fill the hydraulic reservoir.

2.6 fILLINg ThE TANk

DANgER

Fuel is highly ammable and its vapors are explosive. To prevent personal injury or property damage:

Store fuel only in approved containers, in well ventilated, unoccupied buildings, away from

sparks or ames. Do not ll the fuel tank while the engine

is hot or running. Spilled fuel could ignite if it comes in contact with hot parts or sparks from ignition. Do not start the engine near spilled fuel. Never use fuel as a cleaning agent.

Fill the inlet line leading from the reservoir to the pump before

3. start-up. Loosen the fitting at the pump on this inlet line until oil bleeds out.

Start the engine and run at the lowest possible RPM.

4. As you purge air from the unit, the oil level in the reservoir

5. will drop and bubbles may appear in the fluid. Refill the reservoir as necessary.

Run the feed roller in both directions for several minutes until

6. any remaining air purges from the unit. Refill the reservoir as necessary.

4.7 chIppER fEED coNTRoLLER

The chipper is equipped with a pre-programmed feed controller. The controller is located on the chipper housing above the chipper chute. The controller serves a variety of functions including monitoring chipper disk RPM, controlling the feed roller, and providing routine maintenance alerts. The control bar located on the feed chute will control the feed roller.

The controller functions are further detailed below:

The controller operates the feed roller. The controller moni-

1. tors the RPMs of the chipper disk and won't operate until the engine is at full RPM. If the chipper disk drops below the normal operating RPM, the feed roller stops. When the chipper disk returns to the normal operating RPM, the feed roller will reengage.

NoTE

It is important to bring the engine to full RPM before operating the chipper. The chipper feed controller requires the chipper disk to turn at full RPM in order to operate.

The controller also has a “try again” feature. The controller

2. monitors the hydraulic pressure of the feed roller. If it senses the level is too high (the feed roller becomes obstructed) the controller will reverse the feed roller , removing the material trying to be chipped. The controller will then engage the roller into the forward position and try to feed the material again. If this cycle continues, remove the obstruction manually. Trim or reposition material if necessary.

The feed controller is programmed to display the following

OPERATION

4.10 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

1. material.

These machines are most effective when chipping material

2. 0-6" in diameter. Although this machine will accept material up to 8", you may see a reduction in performance when feeding material larger than 6".

Trim side branches that cannot be bent enough to feed into

3. the chipper chute. hold small diameter branches together in a bundle and feed in simultaneously.

Exclude pieces of metal, rocks, bottles, cans, and other

4. foreign objects when feeding chipable material into the machine.

Feed brush from the side of the chipper chute, rather than

5. from the front. Step aside to avoid being hit by the brush moving into the chipper.

Do not lean over the chipper chute to push objects into the

6. cutting device. use a push stick or brush paddle.

Never use shovels or forks to feed brush. They can be chipped, are expensive to replace, and cause extensive damage. In addition, metal pieces can be ejected from the chipper chute and cause serious injury or death.

Never feed brush into the chipper chute with your feet.

8. Place limb, butt end first, into the chipper chute until it con-

9. tacts 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

10. the engine slows to where it may stall.

Remove the branch and rotate it before reinserting it into the

11. chute if the chipper jams.

Alternately insert and retract the limb or insert continuously

12. at a rate that will not kill the engine.

Chipping dead, dry material will create heat and dull the

13. chipping blades quickly.

Alternate green material with dry material to lubricate the

14. chipping blades for longer life and better performance.

The chipping blades will become dull and will require periodic

15. sharpening. Refer to the Service and Maintenance section for sharpening instructions.

Chipping blades are sharp! use caution when working on machine to avoid injury.

The chipper blades will eventually become dull, making chipping

difcult 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.

1. Small diameter branches do not self-feed.

2. Chips discharge unevenly or have stringy tails, especially

3. when chipping green branches.

Before you sharpen the chipping blades, check for permanent damage. Replace the blade if:

There are cracks, broken corners or nicks greater than 1/8"

5.9.1 hYDRAuLIc fLuID

The machine is tested before shipping. In order to test the ma-

chine, the uid levels are lled. However, before starting the ma-

chine, check the hydraulic uid level in the reserve tank.

WARNINg

Handle pressurized hydraulic uid carefully. Escaping pressurized hydraulic uid may penetrate your skin causing seri-

ous injury. This uid may also be hot enough to burn. Serious

infection or reactions can develop if immediate proper medical treatment is not administered.

Premium hydraulic uids containing high quality rust, oxidation,

and foam inhibitors are required. 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.

5.9.2 hYDRAuLIc fEED MAINTENANcE

The hydraulic pump normally does not require regular uid changes. The system lter should be changed after 250 hours of operation or annual intervals. 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 temperature levels greater than the maximum recommended.

There is a greaseable bearing on each side of the main jack shaft on the main hydraulic feed housing. Grease according to the Maintenance Schedule in Section 5.1.

5.9.3 hYDRAuLIc puMp sTART up

NoTE

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

Follow this start-up procedure when starting a new installation or when restarting an installation in which the hydraulic pump has been removed from the system.

Before starting the hydraulic pump, make sure all system

1. components (reservoir, fittings, etc.) are clean.

Add recommended hydraulic fluid to the reservoir. The hy-

2. draulic fluid should be filtered before it enters the reservoir.

Run the unit and move the control bar in both directions for

3. several minutes until all air is purged from the unit. Refill the reservoir as necessary.

Shut down the engine, check for and correct any fluid leaks,

4. and check the reservoir level. Add fluid if necessary. The hydraulic pump is now ready for operation.

5.9.4 hYDRAuLIc oIL fILTER

using an oil filter wrench, turn the filter counterclockwise.

1. Once the filter becomes loose, turn it out the rest of the way

2. with your hand.

Properly discard old filter.

3. Lube the rubber seal on the new filter with clean hydraulic

4. oil.

Install the filter onto the threaded pipe. Turn by hand until the filter is finger tight.

using an oil filter wrench, tighten the filter another 1/2 turn.

Check hydraulic oil level and fill if necessary.

5.10 gREAsINg

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

LubRIcATIoN

Lubrication of bearings is determined by operating conditions and environment. Lubricate standard bearings with a LIThIuM based grease. Greasing intervals are shown on the next page using the following symbol:

Frequency (50 hours)

gREAsINg INTERvALs

Bearings in extreme environments will require more frequent greasing intervals.

gREAsE fILL AMouNTs

It is preferred that experience dictate ll amounts due to wide

variances in applications, greasing equipment and operating conditions. In most cases, it is best to lubricate in small amounts, under low pressure, until a thin bead of fresh grease is visible at the seal lip area.

Care should be taken when greasing bearings to avoid overll-

ing. Overlling can lead to excessive heat and/or unseating of

the seals Grease should be introduced in small amounts and under light pressure. Whenever possible, the bearing should be rotated slowly while grease is added to ensure equal distribution throughout the raceways.

The chipper models described in this manual have several

bearings that require greasing. Refer to the gures on the next

page for greasing locations and intervals.

WARNINg

Polyuria and lithium based greases are not compatible. Mixing the two grease types may lead to premature failure of the chipper.

WARNINg

The use of pneumatic grease equipment is not recommended unless low pressure is assured.
