Operating
Your Chipper
Shredder
This Operators Manual covers a range of product
specifications for various models. Characteristics and
features discussed and/or illustrated in this manual may
not be applicable to all models. Troy Bilt LLC reserves
the right to change product specifications, designs
and equipment without notice and without incurring
obligation.
WARNING: The operation of any
chipper shredder can result in
foreign objects being thrown into the
eyes, which can damage your eyes
severely. Always wear the safety
glasses provided with this unit or eye
shields before chipping or shredding
and while performing any adjustments
or repairs.
Gas and Oil Fill-Up
Service the engine with gasoline and oil as instructed in
the separate engine manual packed with your chipper
shredder. Read instructions carefully.
WARNING: Never fill fuel tank indoors
with engine running or until the engine
has been allowed to cool for at least
two minutes after running.
Starting Engine
IMPORTANT: Because this manual covers several
different model units, different starting instructions may
apply to your particular engine. Some engines may have
a fuel petcock, some may not. Some engines may have
On/Off switches, other may not. Some units will utilize a
choke system, while others will require priming. These
factors depend on what make and model engine comes
with your particular unit. For these reasons, please refer
to the engine operator’s manual for the correct starting
procedure.
Basic Starting Procedure:
1. Attach spark plug wire to spark plug. Make certain
the metal cap on the end of the spark plug is
fastened securely over metal tip on the spark plug.
2. Open fuel shut-off valve (If equipped) and make sure
the On/Off switch is in the On position (if equipped).
3. Move choke control lever to CHOKE position, if
equipped. If the unit has a primer, prime the motor as
instructed in the engine operator’s manual.
NOTE: A warm engine may not require choking or
priming.
4. Move throttle control lever to FAST position (if
equipped).
5. Grasp starter handle and pull rope out slowly until
engine reaches start of compression cycle (rope will
pull slightly harder at this point).
NOTE: A “clanking” noise may be heard when pulling
the starter rope. It is completely normal and does NOT
indicate a malfunction of any kind.
6. Pull rope with a rapid, continuous, full arm stroke.
Keep a firm grip on starter handle. Let rope rewind
slowly.
7. Repeat the previous steps until engine starts. When
engine starts, move choke control gradually to RUN
position until the engine is running smoothly.
WARNING: Never run the engine indoors
or in a poorly ventilated area. Engine
exhaust contains carbon monoxide, an
odorless and deadly gas.
Stopping Engine
1. Move throttle control lever to STOP position (Model
414) or push rocker switch to OFF (Model 424 & 425).
See Figure 6.
NOTE: See your engine manual packed with your unit for
more detailed instructions.
CAUTION: Never stop the engine by
moving the choke lever into the CHOKE
position. Backfire, fire or engine damage
could result.
