SHREDDING GUIDE

For best results when shredding, follow the guidelines shown in the table below.

MATERIAL SHREDDING METHOD

Twigs and up to 6 mm diameter.

Feed into the feeding hopper at a rate which the product will accept without overloading.

Branches and up to 45 mm in diameter.

Clip off all side growth with secateurs before feeding into the feeding hopper.

Bedding plants, weeds and shrubby growth.

Knock soil and stones off the roots to avoid damage to the blades.

Freshly cut foliage, hedge, and kitchen waste.(i.e. cabbage leaves, vegetable peelings etc.)

With any material having a high moisture content it is advised to feed in some drier sticks at regular intervals to help push the material through the cutting assembly and prevent it from clogging.

Dry sticks and twigs By inserting these at the end of your shredding task, this will help to clean the moisture and plant sap from the inside of the product and the cutting assembly.

• Do not allow garden waste to accumulate before shredding as it will begin to compost, become too damp and clog the cutting assembly. Dry material will help most material to clear the ejection chute. Save some dry sticks until last to help clean the blade area.
  ■ Frequently monitor the build up/collection of shredded material.
  ■ The exit of the discharge chute must be clear at all times to prevent blockages.
  ■ When the collection box is full, turn the product Off before emptying.

WARNING

Do not put your hands up inside the shredder's discharge chute to clear away shredded material while the product is switched on or connected to the mains supply. The blades are sharp. Wear heavy-duty gloves and exercise extreme caution when cleaning and clearing blockages.

WARNING

When feeding long woody branches/stems into the product be careful of whip and vibrations as they get caught by the cutter. The operator must wear eye protection whenever using the product.

WARNING

The cutting device has a tendency to pull branches/stems into the product. Do not try to impede entry of the material being cut once feeding has started. Always wear gloves to prevent skin lacerations when feeding material into the product.

NOTE: In normal use, do not switch off the product until all of the shredded material has cleared the cutter assembly. If the product is switched off too quickly, remaining pieces of material may clog the blade assembly and stall the motor when the product is switched back on.
