WARNING

KICKBACK DANGER (Fig. 1)

One of th e most severe dangers wh en work ing wit h a chain s aw is the pos sibil ity of k ickba ck. Kickbac k may occur when the upper tip of the guide bar to uches a n object, or when the woo d closes in and pinch es the saw chain in the cut . Tip con tact in s ome cases may cause a lightning fast reverse reacti on, kicking t he guid e bar up an d back towa rd you. Pinchin g the saw chain al ong the top of the guide bar may al so push t he guid e bar rap idly ba ck towards you. Eit her of these r eactions may c ause you to los e control of th e chain saw whi ch could result in serious pers onal in jury. Even thoug h your cha in saw has safe ty bui lt into it s design, you should not r ely on th ese saf ety features exclus ively. Kn ow where your guide bar tip is at all ti mes. Kickback doe s occur if you all ow the ki ckbac k zone (1) of the gui de bar to touch an obje ct. Do not use that a rea. Ki ckback from pin ching is caused by a cut closing and pinching t he uppe r side of t he guid e bar. Study your cut an d make sur e it will o pen as you c ut thro ugh. Maint ain control wh en the engine i s running by alw ays keeping a ﬁ rm grip on t he chai n saw with your rig ht hand o n the rea r handl e, your left hand on the front ha ndle an d your thumbs and ﬁ ngers encircling the han dles. Always hol d the chain saw wi th both hands during operation and cut at high engine spee d. Follow manufac turer 's shar pening and maintena nce ins truc tions for the sa w chain. The lack of this mainten ance may increase the possibility of kickback.

BASIC TE CHNIQ UES FOR M AKING FELLING, LIM BING A ND BUCKING CUTS

The inte ntion o f the following i nformation is t o provide you wit h the gener al introduct ion to woo d cutt ing techniqu es.

WARNING

○ T his information does not cover a ll speciﬁ c sit uatio ns, whi ch

may depend on diﬀ erences in terrain, vegetation, kind of wood, form and size of tre es, etc. C onsul t Hitac hi Auth orized S erv ice Centers, forestry agent or local forestry schools for advice on speciﬁ c woo dcut ting pr oblem s in your ar ea. Thi s will make your work more eﬃ cient and saf er.

○ Avoid cut ting in a dvers e weather cond ition s, such as dense fog,

heavy r ain, bitter co ld, hig h winds, etc.

Adverse weath er is often tiri ng to work in and creates pot entia lly

dange rous co nditi ons suc h as slip pery ground.

High winds may force the tree to fall i n an unexp ected d irect ion

causing property damage or personal injury.

CAUTION

Never u se a chain saw to pr y or for any pur pose for which i t is not

intended.

WARNING

○ Avoid stumbling on obstacles such as stumps, roots, rocks,

branc hes and f allen t rees. Watch out for h oles an d ditch es. Be extremely cautious when working on slopes or uneven ground.

Shut oﬀ the engine when moving from one work place to another. Always c ut at wide open thrott le. A slow moving c hain can easily

catch an d force the chai n saw to jer k.

○ Never use th e chain s aw with only one h and. You cannot con trol th e chain s aw properly and you may lose

control and injure yourself s everel y.

Keep the chain saw bo dy close to your body to imp rove con trol

and reduce str ain.

○ When cutting with the upper part of the chain the reactive force

will pu sh the chain sa w towards you and aw ay from the wood yo u are cut ting. (Fig. 22)

Fig. 22

○ Th ere is a ri sk of kic kback if the chain saw is p ushed f ar enou gh

so that yo u begin to cut wit h the nos e of the gu ide bar.

The sa fest cutting method is to cut wi th the bottom part of th e

cha in. Sa wing wi th the upper part m akes i t much m ore di ﬃ cult to control the ch ain saw an d increases th e risk of k ickback.

○ In c ase the chain locked, immediately re lease t he thro ttle l ever. If the t hrottle lever ke eps rot ating at h igh spe ed with t he chai n

locked , the clu tch will overheat causi ng trouble.

NOTE

Always keep the spiked bumper fac e to a tree, because the

chain may suddenly be drawn into a tree, if so equipped.

FELLING

Felling is more th an cutt ing down a tree. You must also brin g it down as near to an intended place as possible without damaging the tree or anyt hing el se. Before fe lling a t ree, carefull y consider all conditions which may eﬀ ect the intended d irect ion, such as: Angle of the tree. Shape o f the crow n. Snow load on the c rown. Wind conditions. Obstacles within tree range (e.g., oth er tree s, power lines, roads, buildings, etc.).

WARNING

○ Always o bser ve the general c ondit ions of t he tree. L ook for

decay an d rot in the trunk which will make it mo re likel y to snap and sta rt to fall before you expect it.

○ Look for d ry bra nches, which may break and hit yo u when you

are working.

Always keep animals and people at least t wice t he tree length

away whil e felling. Cle ar away shrubs a nd branches f rom around the tree.

Prepare a path of retreat away from th e felling direction.

BASIC RU LES FOR F ELLIN G TREES

Norma lly the felli ng consist s of two main cu tting ope rations, n otching and mak ing the felling cut. St art ma king th e upper notch cu t on the side of th e tree facing the feelin g direction. Lo ok thro ugh the ke rf as you saw the lower cu t so you do no t saw too de ep into the trun k. The notch should be deep enough to create a hinge of suﬃ cient widt h and strength. The notc h openi ng shou ld be wid e enoug h to direct the fall of the tre e as long as poss ible. Saw the fell ing cut f rom the

Page 11

other side of the t ree bet ween on e and two inche s (3–5 cm) above the edg e of the notch. (Fig. 23)

WARNING

A major ity of k ickback acc ident s occur d uring I imbin g. Do not us e the nose of the gu ide bar. Be ex tremely cautious a nd

avoid contact ing the l og, other limbs o r objec ts wit h the nos e of the guide bar. Be ex treme ly caut ious of l imbs un der tension. They can spring back towa rds you an d cause l oss of control resulting in injury. (Fig. 26)

27. Felling cut

Never saw c omple tely through the trun k. Always leave a hinge. The hinge guides the tre e. If the trunk is c ompletely cut t hroug h, you lose co ntrol over the fel ling di recti on. Inser t a wedge or a felling lever in the cut we ll before the tre e becom es unst able an d star ts to move. This wi ll prevent the guide bar from b indin g in the fe lling c ut if you have misju dged th e falli ng direction. Make sure no people have come into the range of the fallin g tree be fore you p ush it over.

FELLING CUT, TRUN K DIAM ETER MO RE THA N TWIC E GUIDE BAR LENGTH

Cut a large, wide n otch. Th en cut a re cess into the ce nter of the notch. A lways leave a hinge o n both sides of th e center cut. (Fig. 24) Compl ete the felling c ut by sawing arou nd the trunk as i n the Fig. 25.

Fig. 24

Fig. 26

Stand o n the left side of the tru nk. Maintain a s ecure footin g and rest the cha in saw on the trun k. Hold t he chai n saw clo se to you so t hat you are in full cont rol of it. Ke ep well away from the c hain. Move only when th e trunk i s betwe en you and the cha in. Watch o ut for spr ing back of li mbs und er tension.

LIMBI NG THICK BRANCHES

When limbing thick br anche s, the gu ide bar m ay get pin ched easily. Branc hes under ten sion often s nap up, so cut tro ublesome br anches in small steps. A pply th e same pr inciples as fo r cross cutting. Think ahead and be aware o f the pos sible consequenc es of all yo ur actions.

CROSS CUTTING/BUCKING

Before s tart ing to cu t throu gh the lo g, try t o imagine what is going to happe n. Look out for stresses i n the log a nd cut th rough i t in such a manne r that the guide bar will not get pin ched.
