5. Put on eye and ear protection, and gloves, start the chipper/shredder as instructed in the manual, then set the throttle to fast.
6. Stand to the side of the hopper and make sure you have a stable stance and firm footing.

To start the chipper/shredder:
Turn the fuel lever to the ON position (Pic.8)(8.1).
Set the choke lever to the ON position (Pic.9)(9.1). Turn the engine ON/OFF switch to the ON position (Pic.10)(10.1).
Hold down the engine firmly with one hand on the frame. With the other hand grip the recoil starter cord handle and pull slowly until resistance is felt indicating that the recoil starter is engaged. When resistance is felt pull the cord sharply (Pic.11). Continue this procedure until the engine starts.
When the engine has been successfully started and is running smoothly return the choke lever to the OFF position (Pic.12)(12.1).
When the engine is running, the speed can be adjusted by moving the throttle control lever (Pic.13)(13.1) to the high (indicated by a hare), medium or low position (indicated by a tortoise).
To stop the chipper/shredder:
To stop the engine, turn the engine ON/OFF switch to the OFF position (Pic.14)(14.1).
When the engine has stopped and before storage, turn the fuel lever to the OFF position as shown in Pic.15 (15.1).
To shred twigs, leaves, and brush:

1. Slowly pour the material into the hopper. DO NOT try to stuff too much material in at one time or the machine will jam.

2. Use a 1″ diameter branch to push the material into the hopper if necessary (see Pic.16). DO NOT use your hands! Pic.16 Shredding leaves
   Note: Move the throttle to the idle position, or turn the chipper/shredder OFF, when not actively shredding or chipping.

3. Turn OFF the machine, allow all moving parts to completely stop, and disconnect the spark plug wire before moving the machine, emptying the bag, unclogging the inlets or outlets, filling the gas tank, or performing maintenance and repairs.

Shredding Tips:

• Feed material into the chipper/shredder slowly. If the motor begins to bog down, you are feeding too fast.
• Roots and dirty material will dull or damage the blades.
• Remove the chips often. Allowing the chips to pile up to the outlet will cause the outlet to clog.
• Avoid shredding wet leaves or brush to reduce clogging. If you must shred wet material, alternate wet and dry material.

To chip branches:

1. Stand to the side of the hopper and make sure you have a stable stance and firm footing.
2. Remove twigs and smaller branches from the branch if they might catch on the edges of the funnel and prevent the branch from going in.
3. Place branches into the funnel, thick end first, and allow the blades to draw the branch into the funnel (see Pic.17). Pic.17 Chipping branches
4. When finished chipping, turn OFF the machine, allow all moving parts to come to a complete stop, and disconnect the spark plug wire before moving the machine, emptying the bag, unclogging the inlets or outlets, filling the gas tank, or performing maintenance and repairs.

Chipping Tips:

• DO NOT feed material in excess of the diameter indicated on the funnel cover into the funnel. Large branches will cause the motor to stall.
• Chipping wood when it is green is easier on the machine. The blades will stay sharper longer.
• The chipper/shredder will work best if the blades are sharp. Rotate, sharpen, or replace the blades as soon as chipper/shredder performance begins to deteriorate.

SECTION 4: MAINTENANCE

WARNING
Turn OFF the machine, allow all moving parts to come to a complete stop, and disconnect the spark plug wire before moving the machine, emptying the bag, unclogging the inlets or outlets, filling the gas tank, or performing maintenance and repairs.

• Check the hopper, hopper guard, and funnel for cracks, holes, and loose bolts.
• Check the box frame for cracks or damage.
• Check the entire machine for loose bolts or screws.
• Check the blades and hammers for cracks and dings.
• Check the engine oil level.

Cleaning
Clean the machine after each use. Allow the motor to cool and remove the spark plug wire.
Brush off or vacuum wood chips and wipe off the remaining dust from the exterior of the machine with a dry cloth. DO NOT rinse off the chipper/ shredder with water. Remove any chips or debris from the hopper and the discharge chute.
It is much harder to clean the machine if you allow it to sit for a while after use. You may need to use an engine cleaner to remove the built up resins from the motor. Engine cleaners are available at most auto parts stores.

Maintenance of engine
Spark Plug
After every 50 hours of running the spark plug should be removed. Check the color of the deposits on the end of the spark plug it should be a “Tan” color. Remove all deposits using a stiff brush a brass wire brush is ideal. Check the spark plug gap (Pic.18)(18.1) and adjust if required. The correct gap should be 0.7 to 0.8mm.

Engine oil replacement
Place the machine on a level surface and warm up the engine for several minutes. Then stop the engine.
Remove the oil filler cap (Pic.5)(5.1).
Place an oil pan under the engine. Remove the oil drain plug (Pic.5)(5.2) so that the oil can be completely drained. You will need to use a tube or other similar device to prevent the oil leaking onto the frame of the chipper/shredder.
Check the oil drain plug, gasket, oil filler cap and O-ring and if damaged replace.
Reinstall the oil drain plug.
Add engine oil up to the upper level of the dipstick (Pic.6)(6.1).
Air Filter
After every 100 hours of running or every month, the air filter (Pic.19)(19.1) should be removed, examined for deterioration and cleaned. Clean the air filter thoroughly using environmentally friendly water based degreasing agent. Allow to dry fully then replace the air filter. Warning! Never run the engine without the air filter fitted. Fuel tank filter
After every 150 hours of running or every three months the fuel tank filter (Pic.20)(20.1) should be removed and cleaned. Remove the fuel tank filler cap and the filter, clean the filter thoroughly using environmentally friendly water based degreasing agent and re-fit.
Replacing Blades
