Seven Italy CH420 - Petrol garden shredder - Loncin G420F engine - Electric start

This petrol garden shredder allows reducing weeds and twigs in an easy to handle and suitable size for composting. Shredding operations also allow reducing the material decomposing time.

The large steel hopper can process even very bulky branches and leaves without having to pre-shred them. Thus, it also features a higher capacity that allows entering a large amount of material at a time.

Maximum cutting diameter: 80 mm

The engine of this shredder is also equipped with electric start.

This petrol wood chipper is MADE IN ITALY, featuring the quality of large-sized shredders, thus ensuring maximum results in terms of cutting, speed and reliability.

The machine is compliant with the CE standards.

Warning: Like all wood chippers and garden shredders, it is not suited for shredding grass, leaves, pine needles, etc. (it is intended to shred branches, but it can also grind leaves, needles and others)

Garden shredders intended use:
- The wood chipper must grind only green branches and not dried ones (which would limit its shredding capacity and lead to quick deterioration of the blades);
- The branches must be preferably long, smooth and not knobby (otherwise the cutting diameter would be reduced);
- The branch cutting diameter indicated is the maximum, so it is advised not to shred larger branches. In this case it would be better to purchase a shredder with a larger branch cutting diameter;
- The cutting diameter can vary according to the amounts of wood (e.g: oak, olive, plum and peach are hardwood and can reduce the cutting capacity of the wood chipper);

The outer shredding chamber (the largest and sturdiest in its category) is proportionate to the rotor it includes. It is wide and features a round-shape. It guarantees excellent productivity, as well as the durability of the system.

The machine structure is 100% made of steel. No plastic has been used.

Equipped with anti-vibration rubbers and pneumatic wheels for easy transport.

Adjustable discharge chute, 1 m high from the ground, equipped with adjustable-tilting deflector.

It allows discharging the wood chips directly into a box.

Brand-new reinforced highly sturdy shredding blades

This transmission gives the machine an extraordinary sturdiness, protecting both the motor and the internal shredding rotor from any kind of internal shock or kickback.

In case of a rotor clogging caused, for example, by a too large branch, stones, etc.. there is no risk of breaking the drive shaft and the motor, but the intermediate belt will slip or at least will brake down.

Much longer service life than the standard systems still used by all manufacturers on their petrol-powered models where the engine is directly connected to the shredding unit.

Recommendations for use

To ensure the maximum efficiency and durability of the wood chipper,  the instructions below must be strictly followed. Failure to do so constitutes improper use and carries a serious risk of damage to the product (such damage is not covered by the warranty).

• DO NOT use the wood chipper to shred:

1. Pine needles
2. Grass or piles of leaves
3. Wet garden waste
4. Whole pallets or parts thereof
5. Construction waste
6. Wood and/or roots covered in soil or stones.

These materials, which lack a woody texture, tend to form a paste that blocks the shredding chamber and the discharge chute, overloading the engine. However, branches with leaves may be fed into the machine, provided they are preferably straight in shape.

• DO NOT feed in pallets or construction waste: ensure that the material contains no nails, screws, iron wire or concrete debris. Impact with foreign objects will irreparably damage the cutting rotor and may result in the violent ejection of metal fragments.
• DO NOT shred wood and/or roots covered in soil: the abrasive action of soil and sand on the cutting blades at high speed causes immediate wear. The cutting blade loses its sharpness within minutes, making extraordinary maintenance necessary. Furthermore, the likely presence of stones, even small ones, would inevitably damage the wood chipper.
• Pay attention to wood freshness: the specified maximum cutting diameter refers to ‘green’ wood, i.e. fresh branches recently cut from the tree (which is the ideal time to process them in the wood chipper) and of medium consistency. For very hard types of wood (e.g. oak, olive, plum, peach), the wood chipper’s actual cutting capacity may decrease proportionally to the hardness of the wood. Furthermore, the declared maximum cutting diameter should be considered as an exception  during use and not the standard operating conditions, as it would mean operating the wood chipper continuously at the limits of its capabilities.
• DO NOT shred dry or seasoned wood (e.g. old posts, beams, sticks): the wood chipper is designed to process freshly cut branches. Dry wood is significantly harder than fresh wood and can damage the cutting blades by creating nicks or causing them to lose their sharpness quickly, as well as placing severe strain on the transmission mechanism. 
• DO NOT feed material in when the engine is off or running at low revs: start the wood chipper and always bring it up to full speed before feeding in the material. Similarly, never switch off the engine while there is still material inside the cutting chamber.
• DO NOT FORCE THE FEED: the wood chipper must pull the material in automatically (self-feeding). If the branch does not advance, the blades may be worn or the branch may be too knotty. Forcing material into the hopper could cause the cutting rotor to jam and result in serious damage to the transmission.
• DO NOT operate the wood chipper with worn or damaged blades: under these conditions, shredding occurs by ‘impact’ rather than by ‘cutting’. The resulting strong vibrations and stresses can cause serious structural damage to all components of the wood chipper.
• Fuel storage:

1. Use approved tanks
2. Check that metal tanks are clean and free from corrosion
3. Store fuel in a cool, dry place away from direct sunlight
4. Use the petrol within 30–60 days
5. If necessary, use a stabiliser to extend its shelf life

If the machine is to be left unused for a prolonged period, empty the fuel tank or use fuel containing a stabiliser additive.
