1. NOTE Never cut through to the notch Always leave a band of wood between the notch and back cut approximately 5 cm 2 in or one tenth the diameter of the tree This is called hinge or hinge wood It controls the fall of the tree and prevents slipping or twisting or shoot back of the tree off the stump See Figure 32 On large diameter trees stop the back cut before it is deep enough for the tree to either fall or settle back on the stump Then insert soft wooden or plastic wedges into the cut so they do not touch the chain Drive wedges in little by little to help jack the tree over See Figure 33 When bucking or felling with a wedge it may be necessary to remove the SAFE T TIP anti kick back device to allow the bar to be drawn through the cut After you complete the cut reinstall the tip immediately 5 As tree starts to fall stop the chainsaw and put it down immediately Retreat along the cleared path but watch the action in case something falls your way WARNING Never cut through to the notch when making a back cut The hinge controls the fall of the tree this is the section of wood between the notch and back cut UK NOTCH APPROX 1 3 DIAMETER OF BACK CUT 5 cm 2 in Page 21 OPERATION REMOVING BUTTRESS ROOTS A buttress root is a large root extending from the trunk of the tree above the ground Remove large buttress roots before felling Make the horizontal cut i2. 350 cm 11 8 oz Ife EL In E 33 46 cm 12 16 in dirimens tT 8 25 9 5 mm 375 in 1 25 mm 050 in uc Let DE UL LEM ec iM ien Semi Chisel LoPro Skip Tooth Bijou cit ES 6 7 tooth Brig ine displace imi it E 33 cm 2 0 cu in 2 MR em 1 33 kW 1 78HP Maxdmulmengiiespegsd with altae Illi 12 500 min t Pr 2 600 3 400 min Soundpre sse EVENS TIB I ELA da 99 4 LpA dBA eoundnpowerlevslist SOT sant suyay tin Eo d C Duden assis asap 112 0 LwA dBpA Vibration ISO 7505 ginti CE t En 4 3 M S i O TE u u i non 10 7 M S UK Page 8 FEATURES FRONT HAND GUARD CHAIN BRAKE SILENCER FRONT HANDLE CYLINDER gt Eee CHOKE LEVER PRIMER BULB STARTER GRIP STARTER FAN HOUSING FUEL MIX CAP UK Page 9 TRIGGER RELEASE THROTTLE LOCK BUTTON CHAIN OIL CAP SAFE T TIP CARBURETTOR ADJUSTMENT REAR HANDLE THROTTLE TRIGGER OPERATION For your safety study this entire manual before operating the saw Pay particular attention to the precautions and instructions listed in the operator s manual WEAR HEAD
