Page 7: Product Description
Translation of original operating manual Product Description Technical data 2.1.1 Overall view 2.1.2 Application The wide version of the mechanical felling wedge is used in harvesting of large and medium diameter trees. The narrow version is used in harvesting of small and medium diameter trees. Compared to traditional felling wedges, the potential to unscrew and reposition the wedge, when the spreading height is too low, represents a significant improvement and simplification of the workflow.

Translation of original operating manual Basic Saftey Instructions Saftey Instructions Statutory safety instructions (e.g. "Forestry" accident prevention regulations) must always be observed as a priority, regardless. Only mentally and physically capable persons, who are accordingly trained and instructed, should be employed. Employment restrictions for persons not of full age must be observed. The operator must be trained in felling and forest work.
Page 10 Translation of original operating manual The employer must ensure that felling work is not started until it has been ensured that only persons who are involved in felling trees are in the felling area. Before the felling cut the saw operator has to give a warning sign.

Page 13: Danger Zones When Felling
Translation of original operating manual Danger zones when felling 1 tree length 2 tree lengths The falling area of a tree and consequently the direct area of danger is basically the circular area with a radius of at least twice the tree length around the tree to be felled. Due to special danger situations for example on slopes, it may be necessary to extend the fall area and danger area beyond twice the tree length during felling.
Page 14: Configuration And Function
Translation of original operating manual Configuration and Function Layout NOTE The end stop has a left-hand thread and must be fitted with a medium-strength bolt adhesive so that it cannot come loose. When installing the castellated nut, take care that you don´t distort the bearing point. 4.1.1 Performance Characteristics, Dimensions and Weight Series:...
Page 15: Functional Description
Translation of original operating manual Functional description The mechanical felling wedges from Koller are operated by means of a ratchet. When felling large diameter timber we recommend the optional a telescopic ratchet. (The telescopic ratchet only eases the operation; the maximum torque stays the same!) To avoid tilting effects during the rotation of the threaded spindle, it was built into the feed wedge and thus does not protrude beyond the felling wedge.
Page 16: Operation
Translation of original operating manual Operation Saftey instructions for operation Observe the basic warnings in chapter: "3 Basic safety instructions" The operator must check the equipment before every use (visual inspection) Each chain saw operator is responsible for the tree he fells The chainsaw chain must never contact the felling wedge while cutting otherwise the saw may kickback or break the chain and cause serious injury Position at least one traditional felling wedge in time so that the cut remains open and the saw bar...
Page 17: Operation Of The Device
Translation of original operating manual DANGER Danger of injury or death through incorrect handling! A lack of knowledge or expertise can result in serious injury or death.  The mechanical felling wedge does not replace a cable winch!  The operator must be trained in felling and forest work. Completion of a qualified course is recommended.
Page 18 Translation of original operating manual Position the wedge so that the centre line of the spindle is parallel to the saw plane. This ensures that the wedge does not rub on the cut surfaces when screwing in and that the wedge does not get bent which can cause the wedge to break or getting bent.
Page 19: Inspection Before Starting Daily Felling Operations
Translation of original operating manual CAUTION Risk of injury from sharp edges! The pinch pattern on the spreading plate can have sharp edges. Operating conditions may give rise to sharp edges and burrs. There is a risk of cuts and abrasions.
Page 20: Maintenance
The initial lubrication of the felling wedge is done with Fuchs WSP 5040 (Koller article number V- 0700208). This grease is an extremely pressure-resistant special grease of the type "KPF" with very good emergency running properties for the exceptionally high loads.
Page 21 Translation of original operating manual An oil spray or the like is not suitable for lubrication of the felling wedge! If the optimal original grease is not available, use of very high quality multipurpose grease is possible but comes along with lifespan reduction. Examples of common high-quality multipurpose greases are: Nils Atomic RH, BP Energrease LCX 6002, Eni Longtime Grease 2, Lukoil Signum EPW2, etc.
Page 22: Function Check
Function check Without load the plastic wedge must be able to be screwed in and out without significant resistance and friction in the entire working area.

Translation of original operating manual Transport Saftey instructions for transport Use a protective cover to transport all cutting and pointed tools and equipment so that persons are not endangered.
