Checking the chain lubrication

Checking the chain brake

Do not work with the chain saw without first checking

the chain brake!

- Start the motor as described (make sure you have a good

footing, and place the chain saw on the ground in such a

way that the guide bar is free of contact).

- Grasp the tubular handle

firmly with one hand and hold the

grip with the other.

- Switch on the motor and press the hand guard (I/7) in the

direction of the arrow

with the back of your hand until the

chain brake engages. The chain should stop immediately.

- Switch the motor off

Immediately and release the chain

brake.

IMPORTANT: If the saw chain does not stop instantly

when you carry out this test,

do not under any circum-

stances use the saw! Take the chain saw to a DOLMAR

service center.

Never saw when a sufficient chain lubrication is not guaranteed.

Otherwise the life of the sawing device will be reduced. Before

starting work check the oil level in the tank and the oil feeding.

Check the fed oil quantity by following the instructions below:

- Start the electric chain saw.

- Hold the running chain saw approx. 6" (15 cm) above a

trunk or the ground (use an appropriate surface).

If the lubrication is sufficient, you will see a light oiltrace

because oil will be centrifuged from the chain saw.

Pay attention to the direction the wind is blowing and avoid

unnecessary exposure to the oil spray!

Using the chain saw

Always be sure of your footing and hold the chain saw

firmly with both hands while the motor is running.

Felling a tree

When bucking and felling operations are being performed by

two or more persons, at the same time, the felling operation

should be separated from the bucking 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 utility company

should be notified 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.

A retreat path should be planned and cleared as necessary

before cuts are started. The retreat path should extend back

and diagonally to the rear of the expected line of fall as shown

in Fig. A. The next working place is at least 2 tree lengths

away.

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 where felling cuts are to

be made.

Notching undercut

Make the notch 1/3 the diameter of the tree, perpendicular to

the direction of fall as shown in Fig.B. Make the lower hori-

zontal notching cut first. This will help to avoid pinching of

either the saw chain or the guide bar when the second notch

is being made.
