Section 4: Operation 15

Wet, soggy, or “green” materials will be

shredded to a medium consistency when

using the Bar Grate. However, to shred

these materials to an even finer consis

tency, you may wish to process the mate

rial a second time.

If you do not have the optional Bar Grate

attachment, try alternating small wet and

small dry batches of material to help pre

vent clogging the discharge screen.

A DANGER

Do not shred brush, branches, or other

dry materials when the Bar Grate Is

Installed. Materials will exit the

discharge opening at high speed and

wiil not be properly processed.

A DANGER

Before removing jammed or clogged

material, shut the engine off, wait for

all moving parts to come to a stop and

disconnect the spark plug wire and

move it away from the spark plug.

Use only a long wooden stick or a long-

handled shovel to clear away dis

charged materials or blockages.

REMOVING/INSTALLING DISCHARGE

SCREEN OR BAR GRATE

It may be necessary to remove the stan

dard discharge screen for any of these

reasons:

1. The screen may need cleaning. The

hoies in the screen may be ciogged,

preventing materiais from being prop-

eriy discharged.

2. To process wet or green materials.

This is best accompiished by removing

the screen and installing the optional

bar grate attachment.

3. To change the size of the discharged

materiai. Remove the standard screen

and replace it with one of the optional

screens (with different size holes).

A DANGER

Rotating cutting blades inside discharge

opening will cause serious personal

injury. Biades cut 1/4-inch from dis

charge screen or bar grate attachment.

Before removing or installing the dis

charge screen or bar grate, be certain

the engine is off, all moving parts have

stopped completely, and the spark plug

wire is disconnected and kept away

from the sparkplug.

Discharge Screen or Bar Grate Removal

1. Stop the engine and wait for ail moving

parts to come to a complete stop. Discon

nect the spark plug wire and secure it

away from the spark plug.

2. Move the unit away from any dis

charged material that could block access

to the screen or bar grate.

3. Remove two hair pin cotters (A, Figure

4-5) from two small studs (C) securing

ends of the two discharge screen rods (B).

(B). Support the screen or bar grate so

that It doesn’t fall on you.

5. If the screen doesn’t drop out, hook

the end of a discharge screen rod into a

hole in the screen (Figure 4-6). Pry the

screen downward until it drops free.

too small for the screen retainer rod —
