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 efciently.
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 deector vertically, as this will reduce 
the airow, 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. Backre 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.
