5. The chain brake does not stop the chain immediately.
6. The chain brake does not stay in the disengaged position without aid.

FELL A TREE
Figure 9.
It is recommended that the first-time user should, as a minimum practice, cutting logs on a saw-horse or cradle.

Before you start to fell a tree, make sure that

• The minimum distance between the areas of bucking and felling is two times the height of the tree.
• The operation does not
  • Cause injury to personnel.
  • Hit utility lines. If the tree touches utility lines, immediately tell the utility company.
  • Cause losses in property.
• The user is not in the dangerous area, for example, the downhill side of the area.
• The escape paths that extend back and diagonally behind the felling direction are clear. The felling direction is controlled by
  • The natural lean of the tree.
  • The location of larger branches.
  • The wind direction.
• There are no dirt, stones, loose bark, nails, and staples on the tree.

1. Make a lower level notching cut. Make sure that this cut is

2. 1/3 width of the diameter of the tree.

3. Perpendicular to the felling direction.
   CAUTION
   The level notching cut helps prevent pinching of the saw chain or the guide bar when you make the second notch.

4. Make the felling cut no less than 50 mm and higher than the level notching cut. Make sure that this cut

5. Is parallel to the level notching cut.

6. Keeps sufficient wood to become a hinge which prevents the tree from twisting and felling to the wrong direction.
   When the felling cut gets near the hinge, the tree falls. Stop the felling cut if the tree

7. Does not fall to the correct direction or

8. Moves backwards, causing the cutting bar and chain to become stuck in the cut.

9. Use felling wedge to open the cut and let the tree fall to the correct direction.

10. When the tree starts to fall,

11. Remove the chainsaw from the cut.

12. Stop the machine.

13. Put the machine down.

14. Go away through the escape path. Be careful with overhead branches and your footing.

LIMB A TREE
Figure 10.
Lambing is to remove the branches from a fallen tree.

1. Keep the larger lower branches to hold the log off the ground.
2. Remove the small limbs in one cut.
3. Limb the branches with tension from the bottom to up.
4. Keep the larger lower branches as a support until the log is limbed.

BUCK A LOG
Figure 11-12.
Bucking is to cut a log into lengths. Keep your body balance. If it is possible, lift the log and hold it with branches, logs or chock.

• When the log is held along the full length, cut it from the top.
• When the log is held on one end,
  • Cut the first time 1/3 of the diameter from the bottom.
  •  Cut the second time from the top to complete the bucking.
• When the log is held on two ends,
  • Cut the first time 1/3 of the diameter from the top.
  • Cut the second time lower 2/3 from the bottom to complete the bucking.
• When the log is on a slope,
  • Stand on the uphill side.
  • Control the chainsaw.
  • Hold the handles tightly.
  • Release the cut pressure near the end of the cut.

NOTE
Do not let the chain touch the ground.

When bucking is complete,

1. Release the trigger.
2.  Stop the chainsaw fully.
3. Move the chainsaw from tree to tree.

MAINTENANCE

• CAUTION
  Do not let brake fluids, gasoline, petroleum-based materials touch the plastic parts. Chemicals can cause damage to the plastic, and make the plastic unserviceable.

• CAUTION
  Do not use strong solvents or detergents on the plastic housing or components.

• WARNING
  Remove the battery pack from the machine before maintenance.

ADJUST THE CHAIN TENSION
Figure 5.7.

• The more you use a chain the longer it becomes. It is therefore important to adjust the chain regularly to take up the slack.
• Tension the chain as tightly as possible, but not so tight that you cannot pull it round freely by hand.

WARNING
A slack chain may jump off and cause serious or even fatal injury.

CAUTION
Wear protective gloves if you touch the chain, bar or areas around the chain.

1. Stop the machine.

2. Loosen the lock nuts with the wrench.
   NOTE
   It is not necessary to remove the chain cover to adjust the chain tension.

3. Turn the chain adjustment screw clockwise to increase the chain tension.

4. Turn the chain adjustment screw counterclockwise to decrease the chain tension.

5. When the chain is at the wanted tension, tighten the lock nuts.

6. Pull the chain in the middle of the guide bar at the bottom away from the bar. The gap between the chain guide and the guide bar should be between 3 mm and 4 mm.

SHARPEN THE CHAIN
Sharpen the chain if it is not easy for the chain to go into the wood.

NOTE
We recommend that your dealer, which has an electric sharpener, perform important sharpening work.

Figure 13-14.

1. Tensioning chain.
2. Sharpen the cutters corner with a 4.0 mm diameter round file .
3. Sharpen the top plate, side plate and depth gauge with a flat file.
4. File all the cutters to the specified angles and the same length.

NOTE
During the process,

• Keep the file flat with the surface to be sharpened.
• Use the midpoint of the file bar.
• Use light but firm pressure when sharpening the surface.
• Lift the file away on each return stroke.
• Sharpen the cutters on one side and then move to the other side.

Replace the chain if:

• The length of the cutting edges is less than 5 mm.
• There is too much space between the drive links and the rivets.
• The cut speed is slow
• Sharpening the chain many times but it does not increase the cutting speed. The chain is worn.

GUIDE BAR MAINTENANCE
Figure 15.

NOTE
Make sure that it is turned over periodically to keep symmetrical wear on the bar.

1. Lubricate the bearings on the nose sprocket (if present) with the syringe (not included).
2. Clean the bar groove with the scraping hook (not included).
3. Clean the lubrication holes.
4. Remove burr from the edges and level the cutters with a flat file.

Replace the bar if:

• the groove is not fit with the height of the drive links (which must never touch the bottom).
• the inside of the guide bar is worn and make the chain lean to one side.

TRANSPORTATION AND STORAGE

• Before you move the machine, always
  • Remove the battery pack from the machine.
  • Keep hands clear of the lock-out button.
  • Put the guide bar cover on the guide bar and the chain.
• Before you put the machine into storage, always
  • Remove all residual oil from the machine.
  • Remove the battery pack from the machine.
  • Clean all unwanted material from the machine.
  • Make sure that the storage area is
  • Not accessible for children.
  • Away from agents which can cause corrosion, such as garden chemicals and de-icing salts.
