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 MAKITA service center.
Checking the chain lubrication
J |
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. 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.
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
A
45°
= felling operation
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.
