Oil Filling; Checking The Automatic Oil Function - Ayce SF7J139D-2 Original Instruction Manual

Adjusting chain tension
Warning!
The saw chain has very sharp edges. Wear protective gloves for
safety.
To adjust the chain tension as follows:
1. Disconnect the chain saw from the mains.
2. Place the chain saw on a firm surface.
3. Check the tension by pulling the chain in the middle of guide bar away from the guide
bar with your middle finger and thumb.
4. The tension is correct when the chain snaps back after being pulled away 3-4 mm
from the guide bar. There should be no sag between the chain and the guide bar.

5. Turn hand wheel to increase or reduce the chain tension.
6. Once chain tension is correctly set, please always tighten the knob to fix the sprocket
cover in place.
Warning!
Do not over tension the chain as this will lead to excessive wear
and will reduce the life of bar and chain. Over tensioning also
reduce the amount of cuts you should get.
Check whether all chains lie correctly in the groove of guide bar.

Oil filling

Note: The chain saw is shipped without oil in it, the chain saw must never be used
without oil or with an oil level that is below the indicator.
Warning: Always ensure that the chainsaw is switched off and the plug is removed
from the power outlet before making any adjustments.
1. Remove oil tank cap. (Fig.11)
Fig. 11
2. Fill oil tank with chain lubricating oil. (Fig.12)
3. Check the oil level periodically, through the oil level indicator. (Fig.13)
Fig.13
4. Tighten oil tank cap firmly for good seal, this will avoid oil seepage from tank.
5. Wipe off excess oil.
Note: It is normal for oil to seep when chain saw is not in use. Empty oil tank after
each use to prevent seepage.

Checking the automatic oil function

Warning! Check the automatic oil function before each use.
Check the automatic operation of the chain lubrication by pointing the tip of the
switched–on saw towards a piece of paper laying on the ground, if a patch of oil appears
and becomes larger, then the automatic oil function is working. (Fig.14)
If there are no traces of oil even though the oil tank is full. Then the automatic oil
function is not working.
If the automatic oil function is not working. remove the chain bar and clean out the
oil ways of the chainsaw and chain bar, after reassembled if the chainsaw is still not
working, take it to an authorized service center.
