Use and Care Manual

Feed limbs or branches through cut-end rst, leaving the bushy
head on. This helps guide the limb down the feed hopper and
reduces spinning and bouncing of small pieces back up the feed
hopper. Some side branches may require pre-cutting so that the
branch will self-feed more efciently.
It is always advisable to process freshly cut materials, as wooden
branches get very hard, they become springy when dried out and
can make the knives dull more quickly.
While operating the machine, keep a wooden stick handy,
approximately 1 inch in diameter by 2 feet long. This stick will be
useful to push in short, brushy and very leafy materials and keep
the feed hopper clear.
Do not force material into the machine. If it does not chip well, the
chipper knives may need sharpening or to be replaced, or the gap
between the knives and the wear plate needs adjusting .
Do not overload the machine by feeding too much material in to
the feed hopper at one time. If you hear the speed of the engine
decreasing, immediately stop feeding material in to the machine.
Do not resume feeding material into the machine until the engine
has returned to full speed.
The chipper shredder can clog up with soft, wet, or brous
materials. However, if you feed soft materials intermittently with
branches, there should be no problem, as the chipper shredder
tends to clean out any residue left in the machine.
If any stringy material wraps around the rotor shaft, remove it
before it works its way into the bearing.
If the chipper shredder stalls from overloading or clogging, turn
off the engine’s power switch and wait until the cutting disk is
completely stopped and the belt drive is disengaged. Allow the
engine to completely cool and switch the engine to off. Open
the housing cover to clear and remove all the materials from
the housing. Lock the housing cover, switch the engine to the on
position, and start the machine again to resume operation.
As the discharge material plies up, move the chipper away from
the pile. This will keep the material from backing up the discharge
chute. Do not position the deector vertically, as this will reduce
the airow, impeding the discharge and causing blockage.
IDLE SPEED
Set the throttle control lever to the SLOW position to reduce
stress on the engine when chipping is not being performed.
Lowering the engine speed will help extend the life of the engine,
as well as conserve fuel and reduce noise level.
STOP ENGINE
To stop the engine in an emergency, simply turn the engine switch
to the OFF position. Under normal conditions, use the following
procedure:
1. Move the throttle lever to the SLOW (
) position.
2. Let the engine idle for one or two minutes.
3. Turn the engine switch to the OFF position.
4. Turn the fuel valve lever to the OFF (
) position.
Make sure the machine is level and stable to avoid
unnecessary vibrations.
Do not operate on concrete or other hard surface.
Do not open the housing cover unless the engine and
cutting disk are completely stopped and the belt drive
is disengaged.
Do not move the choke control to CLOSE to stop the
engine. Backre or engine damage may occur.
Do not disengage the belt drive with the machine
running. This will cause friction and vibration on the
belt drive.
The engine is tted with an oil alert and will not start if
the oil level in the sump is too low. It may also stop if it
is operated on a steep slope.
To shut down the machine, move the throttle control
lever to idle speed, turn the engine switch to the OFF
position, and it will gradually come to a standstill.
Sudden stopping at a high speed under a heavy load
is not recommended. Engine damage may result.
Wait until the machine completely stops. Allow the engine to
completely cool. Remove the engine’s spark plug. Then clean out
the interior of the machine and its discharge chute.
