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 flammable 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 combustion engine that burns gasoline (a hydrocarbon fuel). Therefore, your power equipment must be equipped with a spark arrester muffler in continuous effective working order. The spark arrester must be attached to the engine exhaust system in such a manner that flames or heat from the system will not ignite flammable 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,

2.8 filling the tank

danger

Gasoline is highly flammable and its vapors are explosive.To prevent personal injury or property damage:

Store gasoline only in approved containers, in well ventilated, unoccupied buildings, away from sparks or flames. Do not fill 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 gasoline as a cleaning agent.

Fuel Type

For best results use only clean, fresh, unleaded gasoline with a pump sticker octane rating of 87 or higher. In countries using the Research method, it should be 90 octane minimum.

Purchase gasoline in small quantities and store in clean, approved containers. A container with a capacity of 2 gallons or less with a pouring spout is recommended. Such a container is easier to handle and helps eliminate spillage during refueling. DO NOT MIX OIL WITH GASOLINE.

Gasoline Alcohol blends

Gasohol (up to 10% ethyl alcohol, 90% unleaded gasoline by volume) is approved as a fuel for Briggs and Honda engines. Other gasoline/alcohol blends are not approved.

Gasoline Ether blends

Methyl Tertiary Butyl Ether (MTBE) and unleaded gasoline blends (up to a maximum of 15% MTBE by volume) are approved as a fuel for Briggs and Honda engines. Other gasoline/ether blends are not approved.

To Add Gasoline

1.Stop engine, wait for all parts to stop moving and disconnect spark plug wire. Remove key from key switch. Allow the engine and muffler to cool for at least three minutes.

2.Clean area around fuel fill cap and remove cap.

3.Using a clean funnel, fill fuel tank to 1/2" below bottom of filler neck to provide space for any fuel expansion. Install fuel fill cap securely and wipe up any spilled gasoline.

4 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 on the right side 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 screen. The chips can be diverted into a container or onto the ground.

Shredding OPERATION

In this operation, hardened steel shredder knives grind up material fed into the shredder chute. The shredded material then leaves the shredder area by traveling through the discharge screen. The shredded material can be diverted into a container or onto the ground.

WARNING

Before operating your machine, be sure you read and understand all safety, controls 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.

4.Move throttle to full position.

5.Slowly push the engagement handle down to engage the chipper/shredder.

6.For a Cold Engine — Gradually return the choke control to the off position after the engine starts and warms up. The machine may be operated during the warm up period, but it may be necessary to leave the choke partially on until the engine warms up.

For a Warm Engine — Return choke to the off position as soon as engine starts.

4.2 Starting recoil models

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.

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.Turn the key switch to on (if equipped). Pull the recoil starter until the engine starts. Make sure the starting cord retracts.

4.Move throttle to full position.

5.Slowly push the engagement handle down to engage the chipper/shredder.

4.1 Starting electric models

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.

Do not crank the engine continuously for more than 10 seconds at a time. If the engine does not start, allow a 60 second cool down period between starting attempts. Failure to follow these guidelines can burn out, or permanently damage, the starter motor.

If the engine develops sufficient speed to disengage the starter but does not keep running (a false start), the engine rotation must be allowed to come to a complete stop before attempting to restart the engine. If the starter is engaged while the flywheel is rotating, damage to the starter may result.

If the starter does not turn the engine over, shut off starter immediately. Do not make further attempts to start the engine until the condition is corrected. Do not jump start using another battery. Follow the steps below to start the machine.

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.Start the engine by activating the key switch. Release the switch as soon as the engine starts.

For a Cold Engine — Gradually return the choke control to the off position after the engine starts and warms up. The machine may be operated during the warm up period, but it may be necessary to leave the choke partially on until the engine warms up.

For a Warm Engine — Return choke to the off position as soon as engine starts.

14	3 INCH CHIPPER/SHREDDERS

OPERATION

4.3 Stopping the Chipper/Shredder

1.Move the throttle to the slow idle position.

2.Disengage the engagement handle.

3.Allow the engine to run at idle for 30-60 seconds; stop the engine by moving the throttle to the low position or turn off ignition.

4.Allow machine to come to a complete stop.

WARNING

Allow the machine to come to complete stop before inspection or servicing. The rotor is heavy and has inertia built up that will allow the rotor to turn for some time after the clutch has been disengaged. You can tell when the rotor has come to a complete stop when there is no noise or machine vibration present. You can reengage the clutch to slow the rotor to a stop.

4.4 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.

1.Run unit at full operating speed before starting to chip material.

2.Select limbs that are up to 3 inches in diameter. 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.

3.Exclude pieces of metal, rocks, bottles, cans, and other foreign objects when feeding chipable material into the machine.

4.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.

5.Do not lean over the chipper chute to push objects into the cutting device. Use a push stick or brush paddle.

6.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.

7.Never feed brush into the chipper chute with your feet.

8.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.

9.Stop the material feeding and allow the engine to recover if the engine slows to where it may stall.

10.Remove the branch and rotate it before reinserting it into the chute if the chipper jams.

11.Alternately insert and retract the limb or insert continuously at a rate that will not kill the engine.

12.Chipping dead, dry material will create heat and dull the chipping blades quickly.

13.Alternate greener material with dry material to lubricate the chipping blades for longer life and better performance.

14.The chipping blades will become dull and will require periodic sharpening. Refer to the Service and Maintenance section for sharpening instructions.

4.5 shredding Guide

1.Place materials to be shredded (grass, leaves, garden refuse, sticks and branches less than 3/4 inch diameter and 24 inches long, etc.) into the hopper.

2.Exclude pieces of metal, rocks, bottles, cans, and other foreign objects when feeding chipable material into the machine.

3.Never use hands or feet to clear material that has built up inside the shredder chute.

4.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.

5.Feed material evenly into the shredder so that the engine does not bog down or the shredder becomes plugged.

6.Attempting to use the clutch to clear a plugged rotor will cause belt damage. Refer to the Service and Maintenance section for instruction on clearing a plugged rotor.

7.Branches or items that plug or cause the machine to stall should be fed in more evenly or put through the chipper chute.

8.Stop the material feeding and allow the engine to recover if the engine slows to where it may stall.

9.Alternate greener material with dry material to lubricate the shredder knives for longer life and better performance.

SERVICE & MAINTENANCE

WARNING

Before inspecting or servicing any part of this machine, shut off power source,

disconnect spark plug wire from spark plug and make sure all moving parts have come to a complete stop.

5.2 Chipper Blades

WARNING

Chipping blades and shredder knives are sharp! Use caution when working on machine to avoid injury.

The chipper 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.

1.Severe vibration when feeding material into the chipper.

2.Small diameter branches do not self-feed.

3.Chips discharge unevenly or have stringy tails, especially when chipping green branches.

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

1.There are cracks, broken corners or nicks greater than 1/8" (Figure 5.1).

2.The base of the cutting edge is worn or has been re-sharp- ened so that it sits too close to the rotor chipping slot.

1/8"

Figure 5.1 - Causes for Replacement

5.2.1 Removing The Blades

1.Flip the discharge door up. For "S" models, remove the discharge assembly.

2.Remove the 5/16" x 7/8" bolt and nylock nut holding the shredder screen to the bottom of the frame.

3.Disconnect and remove the shredder screen from the machine.

4.Remove the two 5/16" x 1-1/2" hex bolts securing the chipper blade to the rotor. Repeat for the second blade.

5.Inspect blades to see if cracks or nicks are visible. If cracks are present, replace the blades. If nicks can not be removed by sharpening blade, replace the blade.

5.2.2 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 45 degrees (Figure 5.2).

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

4.Makesuresometypeoffixtureisusedtocorrectlyholdtheblade at the proper angle.

5.Be careful when grinding so that the blade does not become overheated and change color. This will remove the heattreated 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.

5 . 3 S e t t i n g C h i p p i n g B l a d e Clearance

The chipping blades should clear the chipper block, located inside the frame on the bottom edge of the chipper chute intake, by 1/16" to 1/8". To adjust the blade clearance, proceed as follows:

1.Remove the rotor shaft end cap and upper shield.

2.Loosen the set screws holding the lock collars on the chute side and engine side bearings (Figure 5.3).

3.Use a punch and hammer to tap the lock collars in the opposite direction of normal rotation. On the chute side bearing, tap punch in a CW rotation. On the engine side bearing, tap punch in a CCW rotation

4.Using a rubber mallet tap the end of the rotor shaft to obtain 1/16" to 1/8" clearance. Rotate the rotor and check the clearance on all chipping blades.

5.Once clearance has been set, the lock collars must be replaced and retightened. Using a punch and a hammer, tap the lock collars in the direction of shaft rotation (clockwise on the engine side bearing and counterclockwise on the chute side bearing) and set them with a hammer tap. Tighten the lock collar set screws.

6.Loosen the set screws holding the belt pulley on the rotor shaft. Move the pulley on the shaft so it is aligned with the engine drive pulley. The pulley should be moved the same amount the rotor was moved, only in the opposite direction. Torque pulley set screw to 160 In-lbs.

7.Insure the pulley drive key is completely seated under the pulley and tighten the set screws.

8.Check pulley alignment by laying a straightedge across the pulley faces. Pulley faces should line up. If not, repeat steps 6 and 7 until the pulley is lined up.

5.4 Replacing the shredder knives

The Rectangular Shredder Knife Kit is a replacement kit to replace existing dull or damaged knives. The serrated shredder knives are designed to offer long life and can be reversed if they become dull. This shredder kit uses an improved knife pattern to provide more complete shredding, durability, and easier feeding. Ensure the knives and spacers are properly installed to maintain rotor balance.

Refer to the Parts Manual for shredder knife kit. To remove the knives or to install a new shredder kit proceed as follows.

IMPORTANT

The serrated edge of the shredder knives should face the same direction as the cutting edge of the chipper blades. Never reuse the #10-24 nut and bolt. Never reuse shafts or spacers if they show signs of wear or abuse. Always install new parts when repairing.

1.Remove the lower belt guard from under engine frame, remove discharge door and discharge screen.

2.Remove the 10-24 x 1-3/8" bolts and nuts from knife shafts.

3.Align shaft with the 5/8" hole in rear of frame and the small hole in front of frame by the chipper chute.

4.Using a small punch or rod, push the shaft out the 5/8" hole in rear of frame.

5.To assemble, insert shaft through the 5/8" hole in rear of frame and slide knives and spacers in their proper order onto the shaft. Install a new 10-24 x 1-3/8" bolt and nut.

6.Repeat steps 3 through 6 to assemble the other three shafts.

7.When completed, install the discharge screen, discharge door and torque all 3/8" bolts to 33 Ft-lbs. Test run machine.

WARNING

Before inspecting or servicing any part of this machine, shut off power source,

disconnect spark plug wire from spark plug and make sure all moving parts have come to a complete stop.

5.11 greaseable Bearings and Pivots

Mounted Unit ball bearings (referred to as “Insert Bearings) are pre-lubricated at our factory and are ready for operation.

Re-lubrication: Re-lubrication of insert 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.

Grease Fill Amounts: It is preferred that experience dictate fill amounts due to wide variances in applications, greasing equipment and operating conditions. The quantities shown in the pictures are recommended amounts. In most cases, it is best to relube 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 re-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.

The chipper models described in this manual have two (2) greaseable bearings and pivots that require greasing. Refer to pictures for greasing intervals and quantities.

1.Chute side bearing (Figure 5.6).

2.Engine side bearing (Figure 5.7).

Figure 5.6 - Chute Side Bearing.

Figure 5.7 - Engine Side Bearing.

NOTE

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

NOTE

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