operation. Check the amount of remaining oil in the oil
tank periodically through the oil inspection window.

To fill the oil, perform the following steps:
1. Clean the area around the oil tank cap thoroughly
to prevent any dirt from entering the oil tank.
2. Lay the chain saw on its side and remove the oil tank cap.
3. Fill the oil tank with the oil. The proper amount of
oil is 150 ml (5.1 fl oz).
4.
Screw the oil tank cap firmly back in place.
5. Wipe away any spilt chain oil carefully.
NOTE: If it is difficult to remove the oil tank cap, insert the
slotted screwdriver into the slot of the oil tank cap, and then
remove the oil tank cap by turning it counterclockwise.

Working with the chain saw

CAUTION:
The first time user should, as a
minimum practice, do cutting logs on a saw-horse
or cradle.
CAUTION:
When sawing precut timber, use a
safe support (saw horse or cradle). Do not steady
the workpiece with your foot, and do not allow
anyone else to hold or steady it.
CAUTION:
Secure round pieces against
rotation.
CAUTION:
Keep all parts of the body away
from the saw chain when the motor is operating.
CAUTION:
Hold the chain saw firmly with
both hands when the motor is running.
CAUTION:
Do not overreach. Keep proper
footing and balance at all times.
CAUTION:
When you use the upper side of
the guide bar for cutting, be careful since the
chain saw may be pushed in your direction if the
saw chain is trapped.
NOTICE:
Never toss or drop the tool.
NOTICE:
Do not cover the vents of the tool.
NOTICE:
When making several cuts, switch the
chain saw off between cuts.

Felling a tree

CAUTION:
Felling work may only be per-
formed by trained persons. The work is hazardous.
When cross-cutting/bucking and felling operations are being
performed by two or more persons at the same time, the
felling operations should be separated from the crosscutting/
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 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.
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 as illustrated.
