Clean Engine Air Intake Area
The engine is air-cooled, and requires unobstructed air
flow into and around the engine. The cooling fins on the
engine cylinder head area must also be kept clear of
chipper and shredding deposits, as well as any other
build-up of debris that could prevent heat from radiating
away from the engine (Figure 14).
To clean the air intake area, remove any external materi-
al build-up, and then blow out the area using a stream of
compressed air. If a compressor is not available, use a
stiff-bristle parts brush, which is available at most auto
parts supply stores.
To clean the cooling fins, brush the area between the
fins with a stiff bristle parts brush, and blow out any
remaining debris with a stream of compressed air. If the
cooling fins are caked with an oily build-up of debris,
using a commercially available engine cleaner aerosol
may help loosen and remove the deposits. If you use
such a product, you must follow all safety and use
instructions to prevent damage to the engine compo-
nents and personal injury to you.
Using a stream of water to clean the engine requires
immediate drying of engine components to prevent
rusting and possible malfunctioning of the electrical
system. If a water stream is used to clean debris, start
the engine immediately, and allow engine heat to speed
drying.

Inspect Chipper Cone
Check the cone to make sure that it hasn’t been dam-
aged or worn excessively by constant use, and replace
it if it is cracked, worn out, or no longer fits securely on
the chipper cone mounting flange.
Cracks, worn areas, and loose attachment points can
cause material to jam or clog when feeding it into the
machine, and may result in kick-back or other hazard to
the operator.
Contact your local dealer for replacement parts if your
unit shows any evidence of these problems, and discon-
tinue use of the unit until the appropriate repairs can be
made.
Check Safety Labels
The safety labels located in various positions on the
Chipper Vacuum have been placed to help remind you
of important safety rules while you are operating or
transporting the Chipper Vacuum unit.
If any label can’t be read or is missing, contact your
local dealer for an immediate replacement. If you must
use the unit without the label, review the label informa-
tion in the “Safety Decals” section of this manual.
Lubricate Wheels, Pulleys, and Sprockets
