• Felling trees &

! the chain saw can only be used to fell trees smaller

in diameter than the length of the chain bar

! secure work area; ensure no persons or animals

are in the vicinity of the falling tree

! never attempt to free a jammed saw with the

motor running; use wooden wedges to free chain

and chain bar

! always wear hard hat to protect head against

falling branches

BEFORE FELLING:

- when cutting and felling operations are being

performed by two or more persons at the same time,

the felling operations should be separated from the

cutting operation by a distance of at least twice the

height of the tree being felled

- trees should not be felled in a manner that would

endanger any person, strike any utility line or cause any

property damage (if the tree does make contact with any

utility line, the company should be notied immediately)

- the chain saw operator should keep on the uphill side

of the terrain as the tree is likely to roll or slide downhill

after it is felled

- an escape path should be planned and cleared as

necessary before cuts are started (the escape path

should extend back and diagonally to the rear of the

expected line of fall) &a

- before felling is started, consider the natural lean of

the tree, the location of larger branches and the wind

direction to judge which way the tree will fall

- remove dirt, stones, loose bark, nails, staples and wire

from the tree

FELLING PROCEDURE:

- make the notch (1 – 2) 1/3 the diameter of the tree,

perpendicular to the direction of falls as illustrated &b

- make the lower horizontal notching cut rst (this will

help to avoid pinching either the saw chain or the

guide bar when the second notch is being made)

- make the felling back cut (3) at least 50 mm higher

than the horizontal notching cut (keep the felling back

cut parallel to the horizontal notching cut) &b

- make the felling 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

begin 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 &c

- 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 falling and watch your footing)

• Limbing a tree *

Limbing is removing the branches from a fallen tree

- when limbing leave larger lower limbs to support the

log o the ground

- remove the small limbs in one cut as illustrated

- branches under tension should be cut from the bottom

up to avoid binding the chain saw

MAINTENANCE / SERVICE

• This tool is not intended for professional use

• Always disconnect plug from power source before

cleaning and/or maintenance

• Always keep tool and cord clean (especially ventilation

slots W 2)

- clean the moulded plastic housing of the chain saw

using a soft brush and clean cloth (do not use water,

solvents or polishes)

- remove and brush clean the cover plate, chain and

chain bar after 1 to 3 hours of use

- clean the area under cover plate, drive sprocket and

chain bar assembly using a soft brush and clean cloth

- clean oil outlet with a clean cloth

• Regularly check for obvious defects such as loose,

dislodged or damaged chain and chain bar, loose xings,

and worn or damaged components

• Carry out necessary maintenance and repairs before

using the chain saw

• Proper functioning of the automatic oiler can be checked

by running the chain saw and pointing the tip of the chain

bar towards a piece of cardboard or paper on the ground

! do not touch the ground with the chain (ensure

safety clearance of 20 cm)

- if an increasing oil pattern developes, the automatic

oiler is operating ne

- if there is no oil pattern, despite a full oil reservoir, see

“TROUBLESHOOTING” or contact your dealer

• If the tool should fail despite the care taken in manufacturing

and testing procedures, repair should be carried out by an

after-sales service centre for SKIL power tools

- send the tool undismantled together with proof of

purchase to your dealer or the nearest SKIL service

station (addresses as well as the service diagram of

the tool are listed on www.skileurope.com)

! before returning, the oil reservoir must be

completely emptied

• Storage (

- if the chain saw is to be stored for a longer period of

time, clean chain and chain bar

- when storing tool, the oil reservoir must be

completely emptied

- use chain guard X when storing the tool

- securely mount storage rail Y on the wall with 4 screws

(not supplied) and horizontally leveled

- use storage rail Y and storage hook Z as illustrated

- be aware of oil leakage when using storage hook Z

- store the tool indoors in a dry and locked-up place,

out of reach of children

TROUBLESHOOTING

• The following listing shows problem symptoms, possible

causes and corrective actions (if these do not identify and

correct the problem, contact your dealer or service station)

! switch off the tool and disconnect the plug before

investigating the problem

★ Tool does not operate

- kickback brake is activated -> pull hand guard S 2

back in position $a

- no power supply -> check power supply

(power cable, circuit breakers, fuses)

- plug not connected -> connect plug

- extension cord damaged -> replace extension cord
