Chipping
WARNING: Never operate the chipper
shredder without chipper chute lowered into
the operating position.
Branches up to 3” in diameter can be fed into the
chipper chute. See Figure 6.Observe the following
guidelines when chipping branches:
Keep both hands firmly on the branch as you feed it
into the chipper chute.
Never feed more than one branch into the chipper
chute at a time.
Never feed anything other than branches (or wood)
into the chipper chute.
Use the tamper to assist in feeding branches into
the chipper chute.
Apply intermittent pressure (force, in short pulses)
while feeding larger (2- 3-inch diameter) branches
into the chipper chute, to avoid bogging or stalling
the engine.
IMPORTANT: Never feed branches with a diameter
greater than three (3) inches into the chipper chute.
Doing so can result in serious damage to your unit’s
chipper blades, flails or impeller.
NOTE: For best performance, always operate the unit
with sharp chipper blades. If a noticeable loss in
performance is encountered while chipping branches,
the chipper blades should be replaced.
Cleaning the Reduction Chamber
WARNING: The impeller’s shredder blade
and chipper blades are sharp. Wear leather
work gloves to protect your hands when
cleaning out the reduction chamber.
If the reduction chamber becomes clogged with debris,
the shredder screen can be pivoted upward so that you
can clean the surrounding area. To do so, proceed as
follows:
Stop the engine and wait untill all moving parts
have come to a complete stop.
Disconnect spark plug wire and keep away from
spark plug. Refer to Page 15.
WARNING: The muffler and surrounding
area will be hot if the engine has been
running. Use caution and protect your hands if
working near the muffler.
Remove the two wing knobs on either side of the
discharge chute and pivot the discharge chute
upward. See Figure 12.
Remove the hairpin clip from the clevis pin which
extends through the housing and shredder screen.
See Figure 12. Retain the clevis pin and hairpin
clip.
Figure 12
Pivot the shredder screen upward and clean the
surrounding area by scraping away debris.
Confirm that the spark plug wire is disconnected
and away from spark plug.
Pull on the starter rope two-to-three times to purge
any remaining debris from the reduction chamber
When the area is cleaned, pivot the shredder
screen downward and re-secure with the clevis pin
and hairpin clip removed earlier.
Reattach the debris collection bag to the discharge
chute, if desired.
