pendicular to the direction of fall. Make the lower hori

-

zontal notching cut first. This will help to avoid pinching 

either the saw chain or the guide bar when the second 

notch is being made.

Felling back cut

Make the felling back cut (

Y

) at least 50 mm higher than 

the horizontal notching cut (

X – W

). Keep the felling back 

cut parallel to the horizontal notching cut. Make the fell

-

ing back cut so enough wood is left to act as a hinge. The 

hinge wood keeps the tree from twisting and falling in the 

wrong direction. Do not cut through the hinge.

As the felling gets close to the hinge the tree should be

-

gin to fall.

If there is any chance that the tree may not fall in desired 

direction or it may rock back and bind the saw chain, stop 

cutting before the felling back cut is complete and use 

wedges  of  wood,  plastic  or  aluminium  to  open  the  cut 

and drop the tree along the desired line of fall.

When the tree begins to fall remove the chain saw from 

the cut, stop the motor, put the chain saw down, then use 

the retreat path planned. Be alert for overhead limbs fall-

ing and watch your footing.

To complete the felling operation, drive a wedge (Z) into 

the horizontal cut (Y).

Beware of falling branches when the tree starts to move.

LIMBING A TREE

Limbing  is  removing  the  branches  from  a  fallen  tree. 

When  limbing  leave  larger  lower  limbs  to  support  the 

log off the ground until after the log is bucked (cut) into 

lengths. 

(Fig.13)

Branches under tension should be cut from the bottom 

up to avoid binding the chain saw.

WARNING: 

Never cut tree limbs while stand-

ing on tree trunk.

BUCKING A LOG

Support logs before bucking. Saw wood only. Avoid con-

tact with stones, nails, etc. when sawing, as these could 

be thrown up or cause damage to the chain or serious 

injury to the operator or bystanders.

Keep a running chain saw clear of wire fencing or the 

ground.

Length  cuts  must  be  carried  out  with  care,  as  leverage 

with the spiked bumper is not possible

Saw at flat angle to avoid kickback.

  1.  

Log supported along its entire length: 

Cut from 

top (over buck), taking care to avoid cutting into the 

ground  

(Fig. 14а)

  2.  

Log supported on one end: 

First, cut from bottom 

(under buck) 1/3 diameter of log to avoid splintering. 

Second, cut from above (over buck) to meet first cut 

and avoid pinching.  

(Fig. 14b)

  3.  

Log supported on both ends: 

First, over buck 1/3 

diameter of log to avoid splintering. Second, under 

buck to meet first cut and avoid pinching. 

(Fig. 14c)

  4.   When working on a slope, operate above or to the 

side of the trunk or laying tree. Be careful not to trip 

over tree stumps, branches, roots, etc.

BUCKING USING A SAW HORSE

For personal safety and ease of cutting, the correct posi-

tion for vertical bucking is essential 

(Fig. 15).

A.  Hold the saw firmly with both hands and keep the saw 

to the right of your body while cutting.

B.  Keep the left arm as straight as possible.

C.   Keep balance on both feet. 

CAUTION: 

While  the  saw  is  cutting,  be  sure  the  chain 

and bar are being properly lubricated.

CUTTING WOOD UNDER TENSION

There  is  a  high  risk  of  accidents  when  sawing  wood, 

branch or trees under tension.

Leave saw jobs like these to professionals 

ONLY

.

Position  and  support  the  trunk  as  shown  on  the  figure, 

so that the cut does not close in, resulting in jamming or 

pinching the chan.  

(Fig.16)

When sawing trunks/logs supported on both ends, start 

the cut from above (

A

) about 1/3 of the diameter into the 

log  and  then  finish  the  cut  (

B

)  from  below,  in  order  to 

avoid splitting of the log and/or jamming of the saw. Avoid 

contact of the chain saw with the ground. When sawing 

logs supported on only one end, start the cut from below 

(

B

) about 1/3 of the diameter into the log and finish the 

cut from above (

B

), in order to avoid log splitting and/or 

jamming of the chain saw.

Maintenance

WARNING:

 Always switch off and unplug the 

power tool prior to any inspection or maintenance. To 

ensure  product  long  life  and  safe  operation,  perform 

the below described maintenance procedures regu

-

larly.

WARNING: 

Always  wear  protective  gloves 

when handling the guide bar and chain.

Regularly  check  for  obvious  defects  such  as  loose, 

stretched or damaged chain and guide bar, loose fixings 

and worn or damaged components.

Check  that  covers  and  safety  devices  are  undamaged 

and  correctly  fitted.  Carry  out  necessary  maintenance 

before using the chain saw.

If the chain saw is faulty, repair should be carried out in 

authorized SPARKY service centre.

NOTE: 

Before returning the chain saw to an authorized 

service centre ensure that the oil tank has been emptied 

completely.

REPLACING THE GUIDE BAR AND CHAIN

Fit the chain and guide bar as described above.

The guide bar groove wears with time.

The bar side contacting with the machine should be re

-

versed periodically to ensure uniform wear.

Check the drive sprocket (19). If it has worn out or dam-

aged due to strain, have it replaced in SPARKY author-
