Notes on working with the machine

What material can be processed?

• Feeding the garden shredder. (8.8)
  GHE150, GHE250S, GHE260S:
  Tree and hedge cuttings as well as thick branch material with side shoots.
  GHE 250, GHE260:
  Organic plant trimmings such as fruit and vegetable cuttings, flower cuttings, leaves, tree and hedge cuttings, as well as thick branches with side shoots and twigs.
  Tree and hedge cuttings should be processed when fresh, as the shredding performance is better with fresh than with dried-out or wet material.

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.

Maximum branch diameter

The data relates to freshly cut branch material:
Maximum branch diameter
GHE150, GHE 250, GHE250S: 35mm; G H E2 6 0 , G H E2 6 0S : 40mm

Working area for operator

• For safety reasons, the operator must stay within the working area (grey areaX) for the entire operating period (while the motor is switched on or the engine is running), particularly in order to prevent injuries due to shredding material that is ejected backwards.

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.
Only switch off the motor when there is no longer any shredding material in the machine. Otherwise, the blade disc may become blocked when operation is resumed.

Overload protection

If an overload of the motor occurs during operation, the built-in overload protection device automatically switches off the motor.

The garden shredder can be started up again after a cooling period of approx.10minutes. Frequent triggering of the overload protection may be attributable to the following causes:

• Unsuitable electric cable (10.1)
• Power overload
• Machine overloaded due to excessive quantities of shredding material or blunt blades

If the cutting unit of the garden shredder is blocked

If the cutting unit of the garden shredder becomes blocked during shredding, immediately switch off the motor and disconnect the power cable. Then remove the feed chute and eliminate the cause of the fault.

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.

• Before feeding the garden shredder, note the working area. (8.4)
• Start the garden shredder. (10.3)

Soft material:

• Throw organic plant trimmings such as fruit and vegetable waste, flower cuttings, leaves, thin branches etc. into the feed opening(1).
  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 motor speed. It should not drop during feeding.
  Hard material:
  Cut up thick branches and branches with side shoots (note the maximum branch thickness (8.3)) beforehand using loppers.

• Feed tree and hedge cuttings as well as branch material slowly into the feed opening(1). The hard material is automatically drawn in by the machine.
  Risk of injury!
  The inclined blade unit can cause branches to kick back.
  In order to prevent injuries caused by kickback, the garden shredder must be fed with hard material in the correct manner:
  Insert longer branches at a slight angle and guide them along the right-hand chute wall to the blade unit in accordance with the symbol(2).
  Observe the correct motor load. (8.5)

Safety devices

Motor restart inhibitor

The machine can only be started via the switch and not by plugging the electric cable into the mains socket.

Safety interlock

The motor/shredding tool may only be operated when the feed chute has been properly closed. If the right closure screw (machine viewed from the front) becomes loose during operation, the motor is switched off automatically and after a few seconds the shredding tool comes to a standstill.

Motor run-down brake

The motor run-down brake shortens the run-down time from when the machine is switched off until the blades stop to a few seconds.

Protective covers

The garden shredder is equipped with protective covers in the feeding and ejection areas. These include the complete feed chute with the upper chute and splash guard, the ejection chute extension and the discharge flap. The protective covers ensure that a safe distance is maintained from the shredding blades.

Blade maintenance

Risk of injury!
Always wear thick gloves.
Maintenance interval: Before each use

• Remove the feed chute. ( ⇒11.3)
• Lock the blade disc. (⇒11.4)
• Check the blades for damage (notches or cracks) and wear; reverse or replace if necessary.

Wear limits of the blades:
The blades must be reversed or replaced before the specified wear limits are reached. STIHL recommends STIHL specialist dealers.

1. Reversible blade
   • On the blades, measure the distance(A) between the bore to the edge of the blade at several points. Minimum clearance: A=6m m

2. Wing blade
   • Measure the blade width(B) at the upward-pointing curved edge of the wing blade. Minimum blade width: B=1 5m m

3. Wing blade (GHE 250, GHE260)
   • Measure the blade width(C) at the upward-pointing curved edge of the wing blade. Minimum blade width: C=1 9m m

4. Shredding blades (GHE 250, GHE260)
   • Measure the blade width(D) at the upward-pointing curved edge of the shredding blade. Minimum blade width: D=1 3m m

Reversing the blades

Blunt reversible blades may only be reversed once. Always reverse both blades.

• Remove the blade set. (⇒11.5)
• Unscrew screws(1) and remove together with nuts(2).
• Remove blade(3) upwards.
• Clean the blade disc.
• Reverse blade(3) and place onto the blade disc with the sharp edge exposed and align the bores.
• Insert screws(1) through the bores and screw on nuts(2). Tighten the nuts(2) to 10Nm.
• Install the blade set. (11.6)

Sharpening the blades:

Blades which are blunt on both sides must be sharpened before resuming work. In order to ensure optimum machine operation, the blades should only be sharpened by a technician. STIHL recommends STIHL specialist dealers.

• Remove the blades for sharpening.
• Cool the blades when sharpening, e.g.with water. The blade must not be allowed to display blue colouring, as this would reduce its cutting quality.
• Sharpen the blade evenly to prevent vibrations due to imbalance.
• Check blades for damage before installing: the blades must be replaced if notches or cracks are visible or if the blades have reached the wear limits.
• Sharpen blades at a sharpening angle of 30°.
• Sharpen the blades against the cutting edge.
• After sharpening, remove any sharpening burr at the cutting edge using fine sandpaper.
• Observe the tightening torques contained in the “Reversing the blades” section when installing the blades.
