6 INCH CHIPPER

ENGLISH

OPERATION

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!

WARNING

4.3 CHIPPER OPERATION GUIDELINES

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  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.

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.

 

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 fitting 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.

CAUTION
