Check the torque of the wheel lug nuts initially and after the first 10 hours of operation.

Torque wheel lug nuts to 108-122 Nm (80-90 ft.-lbs).

Preparing to Start the Machine Review all the machines safety decals.

Use a hard-hat, hearing protection, tight fitting gloves without draw strings or loose cuffs, and eye protection. A mesh visor alone does not provide sufficient eye protection; supplement with protective glasses.

Ensure that you are familiar with safety regulations and shutdown procedures described in this machines Operators Manual and Engine Owners Manual.

Ensure that all guards are in place and in good condition.

Ensure that the blades are in place and in good condition.

Ensure that the work areas and blades are free from metallic objects such as wire, nails, etc. that could be thrown out and injure persons in the vicinity and damage the equipment.

Ensure that everyone, including children and animals, maintain a distance of at least 15 meters (50 feet) from the machine. Debris can be thrown out and injure people and animals.

Disconnect the machine from the tow vehicle, position it on a level location and block the wheels front and back to prevent it from moving.

Check the fuel and oil level of the engine.

Adding Fuel Use unleaded gasoline (87 pump octane minimum). Leaded, regular gasoline may be used if unleaded is not available.

For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).

Ethanol: Gasoline with up to 10% ethanol (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same. Gasoline with 15% ethanol (E15) by volume is not approved for use. Never use gasoline that contains more than 10% ethanol by volume, such as E15 (contains 15% ethanol), E20 (contains 20% ethanol), or E85 (contains up to 85% ethanol ). Using unapproved gasoline may cause performance problems and/or engine damage which may not be covered under warranty.

Do not use gasoline containing methanol.

Do not store fuel either in the fuel tank or fuel containers over the winter unless a fuel stabilizer is used.

Do not add oil to gasoline.


DANGER In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property. Fill the fuel tank outdoors, in an open area,

when the engine is cold. Wipe up any gasoline that spills.

Never fill the fuel tank inside an enclosed trailer. Do not fill the fuel tank completely full. Add

gasoline to the fuel tank until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck. This empty space in the tank allows gasoline to expand.

Never smoke when handling gasoline, and stay away from an open flame or where gasoline fumes may be ignited by a spark.

Store gasoline in an approved container and keep it out of the reach of children. Never buy more than a 30-day supply of gasoline.

Do not operate without entire exhaust system in place and in proper working condition.

DANGER In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. Always place gasoline containers on the ground

away from your vehicle before filling. Do not fill gasoline containers inside a vehicle or

on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.

If a gasoline dispenser nozzle must be used, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

Important: Do not use methanol, gasoline containing methanol, or gasohol containing more than 10% ethanol because the fuel system could be damaged. Do not mix oil with gasoline.

Filling the Fuel Tank 1. Park the machine on a level surface, and stop the

engine. 2. Allow the engine to cool. 3. Clean around the fuel tank cap and remove it (Figure 7).

Figure 7

1. Fuel tank cap

4. Add unleaded gasoline to the fuel tank, until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck.

Important: This space in the tank allows gasoline to expand. Do not fill the fuel tank completely full.

5. Install the fuel tank cap securely, turning it until it clicks.

6. Wipe up any gasoline that may have spilled.

Using the Brush Chipper Service Interval: Before each use or dailyClean the inside

of the cutting chamber cover.

DANGER The machine will cut and amputate hands and feet.

Stay in the operator's position while the machine is running.

Keep all bystanders a safe distance from the machine.

Stop the machine immediately if any people or animals enter the work area.

Never place any part of your body into a position that causes an unsafe operating condition.

WARNING Using the brush chipper may throw wood chips, soil, and other debris into the air which could injure you or bystanders.

Always wear protective gear, such as safety goggles or face shield, hearing protection, tight-fitting gloves without draw strings or loose cuffs when using the machine.

Keep face and body away from the feed opening. Do not overreach. Keep proper balance and footing at all time.

Keep all bystanders at least 15 meters (50 feet) from the machine during operation.

1. Place the brush chipper on level, dry ground, disconnect it from the tow vehicle, and block the front and back of both wheels to prevent any movement.

2. Make sure that you read all the recommendations from the Safety (page 3) section before using the brush chipper.

3. Start the engine; refer to Starting the Engine (page 11) and allow engine to warm up at idle for two minutes.

4. Lower the hopper (Figure 14).



Figure 14

Do not force material into the chipper. If the machine does not chip well, the chipper knife or cutter block may need to be sharpened or replaced.

Extremely hard knots of wood will not process very well. Short stubs that have not self-fed through the chipper can be pushed through with the next branch to be chipped, otherwise simply close the upper chute.

Overloading the hopper will cause the rotor speed to decrease. If you hear the engine RPM decreasing, stop feeding material into the hopper until the engine has returned to full speed (Figure 15).


Figure 15

If you jam the machine and do not stop the engine, it can damage the machine. For this reason, it is important that you immediately stop the engine if the machine becomes jammed, wait 5 minutes to make certain the flywheel and all moving parts have come to a complete stop and cool. Disconnect the spark plug wires, keeping them away from the spark plugs to prevent accidental starting.

Never allow processed material to build up within 76.2 mm (3 in) of the discharge chute opening. Move the machine or the pile as needed. Failure to do so could result in unnecessary jamming of the machine.

To move a pile of processed material, use a spade, rake, or long handle tool. Never use your hands or feet!

Limit the length of large branches to 3 feet long or less; longer lengths could cause the chipper to slow and jam.

Wash out the cutting chamber after each use by spraying water from a garden hose into the hopper while the engine is running at full throttle. Do this for a few minutes to prevent accumulation of matter that can degrade the chipper performance.

To stop the machine; refer to Stopping the Engine (page 12).


Maintenance Important: Before performing any maintenance procedures, first stop the engine, wait 5 minutes to allow all moving parts to come to a complete stop and cool, and disconnect the spark plug wires.
