(Fig. 26)

Kickbacks, skating, bouncing and dropping
Different forces can have an effect on the safe control of the product.

• Skating is when the guide bar moves quickly across the wood.

• Bouncing is when the guide bar lifts off the wood and touches it again and again.

• Dropping is when the product drops down after the cut is made. This can cause the moving chain to touch a part of the body or other objects, causing injury or damage.

• Kickback is when the end of the guide bar touches objects and moves rearward, up or suddenly forward. Kickback also occurs when the wood closes in and pinches the saw chain during the cut. Loss of control can result if the product touches an object in wood.
  (Fig. 27)

• Rotational Kickback can occur when the moving chain touches an object at the top of the guide bar. This can cause the chain to bury into the object and cause the chain to stop immediately. The result is a very fast, reverse reaction that moves the guide bar up and rearward in the direction of the operator.
  (Fig. 28)

• Pinch-Kickback can occur when the saw chain suddenly stops during the cut. The wood closes in and pinches the moving saw chain along the top of the guide bar. The sudden stop of the chain reverses the chain force and causes the product to move in the  opposite direction of the turn of the chain. The product moves rearward in the direction of the operator.
  (Fig. 29)

• Pull-In can occur when the saw chain suddenly stops when the moving chain touches an object in the wood along the bottom of the guide bar. The sudden stop pulls the product forward and away from the operator, which can easily cause the loss of control of the product by the operator.
  (Fig. 30)

Make sure that you understand the different forces and how to prevent them before you operate the product. See To prevent kickbacks, skating, bouncing and dropping on page 13.

To prevent kickbacks, skating, bouncing and dropping

• While the motor runs, make sure to hold the product tightly. Keep your right hand on the rear handle and the left hand on the front handle. Tightly hold with thumbs and fingers around the handles. Do not let go.
• Keep control of the product during the cut and after the wood falls to the ground. Do not let the weight of the product drop down after the cut is made.
• Make sure that the area in which you are cutting is free from blockage. Do not let the nose of the guide bar touch a log, branch or other blockages while you operate the product. (Fig. 31)
• Cut at high motor speeds.
• Do not overreach or cut above shoulder height. (Fig. 32)
• Obey the sharpening and maintenance instructions by the manufacturer for the saw chain.
• Only use replacement guide bars and saw chains specified by the manufacturer. Incorrect replacement guide bars and saw chains may cause chain breakage and/or kickback.
• The risk of kickback is increased if the depth gauge is set too large.

Personal protective equipment

• Always use the correct personal protective equipment when you operate the product. Personal protective equipment decreases the grade of injury if an accident occurs, but does not erase it.
• Do not use loose clothing that can become caught in the saw chain.
• Use an approved protective helmet.
• Always use approved ear protection while you operate the product. Noise for a long period can cause hearing loss.
• Use protective glasses or a face visor to decrease the risk of injury from flying objects. The product can move objects with strong force, such as wood chips and small pieces of wood. This can result in serious injury, including to the eyes.
• Use gloves with chainsaw protection.
• Use pants with chainsaw protection.
• Use boots with chainsaw protection, steel toe-caps and nonslip soles.
• Make sure that you have a first aid kit near.
• Sparks can come from the muffler, the guide bar and saw chain or other sources. Always keep fire extinguishing tools and a shovel to help prevent forest fires.

To fell a tree

1. Remove dirt, stones, loose bark, nails, staples and wire from the tree.
2. Make a notch 1/3 the diameter of the tree, perpendicular to the direction of the fall. (Fig. 44)
3. Make the lower horizontal notch cut. This helps prevent pinching the saw chain or the guide bar when the second notch is made.
4. Make the felling back cut (X) a minimum of 50 mm (2 in) higher than the horizontal notch cut. Keep the felling back cut parallel to the horizontal notching cut so sufficient wood is left to be a hinge. Do not cut through the hinge. The hinge wood keeps the  tree from twisting and falling in the incorrect direction. (Fig. 45) and (Fig. 46)
5. As the felling back cut nears the hinge, the tree starts to fall. Make sure that the tree can fall in the correct direction and not rock rearward and pinch the saw chain. Stop the cut before the felling back cut is complete to prevent this. Use wedges of wood or plastic to open the cut and let the tree fall along the necessary line of fall. (Fig. 47)
6. When the tree starts to fall, remove the product from the cut. Stop the motor, put the product down and use the planned escape path. Be careful of limbs falling from above and monitor your footing. (Fig. 48)

To limb a tree

1. Use larger limbs to hold the log off the ground.
2. Remove small limbs in one cut. (Fig. 49)
3. Cut branches that have tension from the bottom to the top to prevent pinching the saw chain or the guide bar.

To buck a log
CAUTION: Do not let the saw chain touch the ground.

• If the log has support along its full length, cut from the top of the log (known as overbucking). (Fig. 50)
• If the log has support on one end, cut 1/3 the diameter from below the log (known as underbucking).
• If the log has support on the two ends, cut 1/3 the diameter from the top. Complete the cut by underbucking the lower 2/3 of the log to touch the first cut. (Fig. 51)
• If you buck a log on a slope, always stay on the uphill side of the log. Cut through the log while you keep complete control of the product. Then release the cutting pressure near the end of the cut while tightly holding the rear handle and front handle. (Fig. 52)

  • the power level in the engine is low.
  • it is hard to start the engine.
  • the engine does not work correctly at idle speed.

• Do a check of the saw chain lubrication each time you refuel. See To do a check of the saw chain lubrication on page 20.

To adjust the idle speed
Make sure that the air filter is clean and the air filter cover is attached before you adjust the idle speed.

1. Turn the idle adjustment screw, which is identified with a “T” mark, clockwise until the saw chain starts to turn.
2. Turn the idle adjustment screw, which is identified with a “T” mark, counterclockwise until the saw chain stops.
3. The idle speed must be below the speed when the saw chain starts to turn. The idle speed is correct when the engine operates smoothly in all positions.

To do maintenance on the spark arrester mesh

• Use a wire brush to clean the spark arrester mesh. (Fig. 56)

To do maintenance on the spark plug

CAUTION: Use the recommended spark plug. Make sure that the replacement is the same as the manufacturer supplied part. An incorrect spark plug can cause damage to the product.

1. If the product is hard to start or operate, examine the spark plug for unwanted materials. To decrease the risk of unwanted material on the spark plug electrodes:
   a) make sure that the idle speed is correctly adjusted.
   b) make sure that the fuel mixture is correct.
   c) make sure that the air filter is clean.

2. Clean the spark plug if it is dirty. Make sure that the electrode gap is correct. (Fig. 58)

3. Replace the spark plug when it is necessary.

To clean the air filter

1. Remove the air filter cover and remove the air filter. (Fig. 59)
2. Clean the air filter with warm soap water. Make sure that the air filter is dry before you install it.
3. Replace the air filter if it is too dirty to fully clean it. Always replace a damaged air filter.

To sharpen the saw chain
The cutter
The cutting part of the saw chain is called the cutter and consists of a cutting tooth (A) and the depth gauge (B).
The cutters cutting depth is determined by the difference in height between the two, the depth gauge setting (C).
(Fig. 60)
When you sharpen a cutting tooth there are four important factors to remember:

• Filing angle.
  (Fig. 61)

• Cutting angle.
  (Fig. 62)

• File position.
  (Fig. 63)

• Round file diameter.
  (Fig. 64)

To sharpen the cutting teeth
Use a round file and a file gauge to sharpen the cutting teeth. See Saw chain filing and saw chain combinations on page 22 for information on the recommended dimension of the file and gauge for the saw chain installed on your product.
(Fig. 65)

1. Make sure that the saw chain has the correct tension. A chain without the correct tension moves to one side does and not sharpen correctly.
2. Use the file on all the teeth on one side. Then use the file on the cutting teeth from the inner face and decrease the pressure in the reverse direction.
3. Turn the product on the opposite side and use the file on the teeth.
4. Use the file to keep all teeth the same length. Replace a worn saw chain when the length of the cutting teeth decreases to 4 mm (5/32 in).

To adjust the depth gauge setting
Sharpen the cutting teeth before you adjust the depth gauge setting. See To sharpen the cutting teeth on page 19. When you sharpen the cutting tooth (A), the depth gauge setting (C) will decrease. To maintain optimal cutting performance, the depth gauge (B) has to be filed down to achieve the recommended depth gauge setting. See Saw chain filing and saw chain combinations on page 22 to find the correct depth gauge setting for your particular chain.
(Fig. 66)
(Fig. 67)

Note: This recommendation assumes that the length of the cutting teeth is not reduced excessively.
Use a flat file and depth gauge tool to adjust the depth gauge.

1. Put the depth gauge tool above the saw chain.
   Detailed information regarding how to use the depth gauge tool will be found on the package of the depth gauge tool.

2. Use the flat file to file off the tip of the depth gauge that protrudes through the depth gauge tool. The depth gauge setting is correct when you no longer feel resistance as you draw the file along the depth gauge tool.

To tension the saw chain
Note: Check the tension of a new saw chain frequently during its running- in period.

1. Loosen the guide bar nuts that hold the clutch cover. Use the combination wrench. (Fig. 68)
2. Tighten the guide bar nuts by hand as tight as you can.
3. Lift the top of the guide bar and extend the saw chain by tightening the chain tensioning screw. Use the combination wrench. Tighten the saw chain until it does not hang down from the bottom of the guide bar. (Fig. 69)
4. Tighten the guide bar nuts using the combination wrench and lift the tip of the guide bar at the same time. (Fig. 70)
5. Make sure that you can pull the saw chain round freely by hand and that it does not sag. (Fig. 71)

To lubricate the cutting equipment
To do a check of the saw chain lubrication

Do a check of the chain saw lubrication each time you refuel.

1. Start the product and let it run at 3/4 speed. Point the nose of the guide bar at a light color surface almost 20 cm (8 in) away.

2. After 1 minute of running, a line of oil shows on the light surface.

3. If you cannot see the line of oil after 1 minute, clean the oil channel in the guide bar. Clean the groove in the edge of the guide bar. Make sure the guide bar nose sprocket turns freely and that there are no blockages in the lubrication hole. Clean and lubricate
   the tip sprocket.

4. Start the product and let it run at 3/4 speed. Point the nose of the bar at a light color surface almost 20 cm (8 in) away.

5. After 1 minute of running, a line of oil shows on the light surface.

6. If you cannot see the line of oil after 1 minute, speak to your approved dealer.

Transportation

• Put the transportation guard on the cutting attachment during transportation to prevent injuries.
• Make sure that the product can not move to prevent loss of fuel, damage or injury during transportation.

Storage

• Always put the product away safely when not in operation. Leakages and fumes from the product can touch sparks, naked flames from electrical equipment, electrical mowers, relays/switches, boilers and more.
• Always save fuel in an approved container.
• Empty the fuel tank and the chain oil tank when the product is in storage for longer periods of time. Discard used fluids correctly.
• Put the transportation guard on the cutting attachment during storage to prevent injuries.
• Remove the spark plug cap from the spark plug and engage the chain brake before storage.
