Exhaust gases:

Danger to life through poisoning!

In the case of nausea, headache, impaired vision (e.g. decreasing field of view) hearing disorder, dizziness, decreasing power of concentration, stop working immediately. These symptoms may be caused by excessively high exhaust gas concentrations.

The machine generates poisonous exhaust gases when the engine is running. The gases contain poisonous

carbon monoxide, a colourless and odourless gas, as well as other pollutants. The engine must never be operated in closed or poorly ventilated spaces.

The machine must be positioned so that it is not necessary to work facing the direction of the exhaust gases.

Starting:

Place the machine in a stable and upright position prior to starting. The machine must never be operated in a horizontal position.

Exercise care when starting the machine and observe the instructions contained in the section entitled "Operating the machine" ( 11.) .Starting the machine in accordance with these instructions reduces the risk of injury.

Risk of injury!

If the starter rope recoils at speed, the hand and arm will be pulled towards the engine faster than the starter rope can be released. This kickback can result in broken bones, crush injuries and sprains.

Do not stand in front of the discharge opening when starting the engine or switching on the motor. There must be no

shredding material in the garden shredder when it is started or switched on.

Shredding material may be ejected and lead to injuries.

The machine must not be tilted during start-up.

Do not pull the recoil starter rope if the machine is not properly closed and the blades are exposed.

Deactivating the choke:

• Once the engine is running after the starting procedure, the choke must be deactivated immediately by pressing in the choke knob (1) fully.

9. Notes on working with the machine

9.1 What material can be processed?

Both soft and hard material can be processed with the garden shredder.

Soft material:

Organic plant trimmings such as fruit and vegetable waste, flower cuttings, leaves, etc.

• Shredding soft material. ( 11.6)

Hard material:

Tree and hedge cuttings and thick branch material with side shoots.

• Shredding hard material. ( 11.6)

Tree and hedge cuttings should be processed when fresh, as the shredding performance is better with fresh than with dried-out or wet material.

Processing dry shredding material increases the risk of kickback. Branch kickback may result in severe injury to the user.

9.2 What material cannot be processed?

Stones, glass, bits of metal (wire, nails, etc.) or plastic must not be fed into the garden shredder.

As a general rule:

Any materials that do not belong on the compost heap should not be processed using the garden shredder.

9.3 Maximum branch diameter

The data relates to freshly cut branch material:

Maximum branch diameter:

GH 460:60 mm; GH 460 C:75 mm

The size of the feed opening of the branch guide serves only to better accommodate branch material with side shoots and does not indicate the maximum permitted diameter of the shredding material.

9.4 Working area for operator

• For safety reasons, the operator must stay within the working area (grey area X) for the entire operating period.

Risk of injury:

To ensure you are not hit by shredding material that is ejected backwards when processing hard material (branch guide (1) folded out), you should stand slightly to one side of the garden shredder (see grey area X) and not directly behind it.

9.5 Working position of the machine

The garden shredder must only be operated in an upright position. The garden shredder must be stood on its two wheels and on the two wheel carriers as shown for the entire period of operation.

9.6 Correct machine load

The load on the motor or engine of the garden shredder must never cause the speed to drop significantly. Always feed the garden shredder continuously and steadily. If the speed drops when working with the garden shredder, stop feeding the machine in order to relieve the load on the motor or engine.

9.7 Feeding the garden shredder

Risk of injury!

Carefully read the section entitled "For your safety" ( 4.) , subsection "Working with your machine ( 4.6) in particular, and follow all the safety instructions before feeding the garden shredder. It is only permitted for one person to feed the garden shredder.

Risk of injury!

Never reach into the feed opening.

Observe the correct engine load. ( 9.6)

Do not feed material into the two feed openings (1, 2) on the garden shredder at the same time. Danger of blocking.

Soft material:

Before feeding the garden shredder, note the working area. ( 9.4)
- Start the garden shredder.
(⇒ 11.1)
- Throw organic plant trimmings such as fruit and vegetable waste, flower cuttings, leaves, thin branches etc. into the feed opening (1) for soft material.

The feed opening (1) is only for feeding with soft material or with thin branches (up to approx. 10mm in diameter) with numerous side shoots and twigs. The branch guide (3) should be folded in when feeding soft material into the shredder. ( 11.4)

Damp or wet soft material will cause blockages in the machine more quickly. For this reason, feed the garden shredder more slowly and pay particular attention to the engine speed. When feeding soft material into the machine, make sure that the engine hood is not covered with shredding material. Risk of engine overheating due to covered cooling slots.

Always keep the engine clean.

Hard material:

Before feeding the garden shredder, note the working area. ( 9.4)
- Fold out the branch guide (3). ( 11.3)
- Observe the maximum branch diameter. ( 9.3)
- Start the garden shredder. ( 11.1)

Risk of injury:

In order to prevent injuries caused by kickback, the garden shredder must be fed with hard material in the correct manner. If the garden shredder is fed from the rear (i.e. the operator is standing in the working area ( 9.4) , the branch material should be inserted at a slight angle and guided along the left-hand chute wall to the blade unit in accordance with the symbol (4). When feeding, note the maximum branch diameter. ( 9.3) The large feed opening (2) is designed to better accommodate branches with numerous side shoots and twigs.

Cut up thick branches and branches with numerous side shoots (note the maximum branch thickness) beforehand using loppers. Throw thin pruning material (up to approx. 10mm in diameter) into the feed opening (1) for soft material.

• Feed tree and hedge cuttings and branch material slowly into the feed opening (2) of the folded-out branch guide (3). The hard material is automatically drawn in by the machine. You should support and guide longer branches with your hand when shredding.

16. Environmental protection

Shredding material should be composted and not disposed of in household waste.

The machine, its packaging and accessories are all produced from recyclable materials and must be disposed of accordingly.

By disposing of materials separately and in an environmentally friendly manner, recyclable waste can be re-used. For this reason, the machine should be disposed of for recycling at the end of its useful life. Improper disposal may be harmful to health and pollute the environment.

16.1 Disposal

Render the engine unusable prior to disposal.

In particular, remove the ignition lead, empty the fuel tank and drain the engine oil.

Risk of injury from the blades.

Always store an old garden shredder in a safe place prior to scrapping. Make sure that the machine and the blades are kept out of the reach of children.
