not do operate the product on a ladder or in a tree.

(Fig. 30)

Kickbacks, skating, bouncing and dropping

Different forces can have an effect on the safe control of

the product.

• Skating is when the guide bar glides or moves

quickly across the wood.

• Bouncing is when the guide bar lifts off the wood and

touches it again and again.

277 - 007 - 14.10.2019

13

• 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. 31)

• 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. 32)

(Fig. 33)

• 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. 34)

• 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. 35)

Make sure that you understand the different forces and

how to prevent them before you operate the product.

To prevent kickbacks, skating, bouncing and

dropping

• While the engine 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. (Fig.

36)

• 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.

• Cut at high engine speeds.

• Do not overreach or cut above shoulder height. (Fig.

37)

• Obey the manufacturer's sharpening and

maintenance instructions for the saw chain.

• Only use replacement guide bars and saw chains

specified by the manufacturer.

• The risk of kickback is increased if the depth gauge

setting is too large.

Personal protective equipment

• Always use the correct personal protective

equipment when you operate the product. The

personal protective equipment does not erase the

risk of injury. The personal protective equipment

decreases the grade of injury if an accident occurs.

• Generally, clothes should be close-fitting without

restricting your freedom of movement.

• 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 reduce the

risk of injury from thrown objects. The product is

capable of throwing objects, such as wood chips,

small pieces of wood, etc., at great force. This can

result in serious injury, especially to the eyes.

To start the engine when the fuel is too hot

If the product does not start, the fuel can be too hot.

Note:

Always use new fuel and decrease the operation

time during warm weather.

1. Put the product in a cool area away from open

sunlight.

2. Let the product cool down for 20 minutes at

minimum.

3. Press the air purge bulb again and again for 10-15

seconds.

4. Obey the procedure to start a cold engine. Refer to

To start a cold engine on page 17

.

To stop the engine

• Push the stop switch to stop the engine.

Note:

The stop switch automatically goes back to its

initial position.

To use a spiked bumper

A spiked bumper holds the wood as you cut. The spiked

bumper is a pivot between the engine body and the

guide bar.

1. Put the lower end of the spiked bumper at the

correct felling hinge width.

2. Push against the front handle with your left hand and

lift the rear handle with your right hand.

3. Cut until you get the correct felling hinge width.

Note: The felling hinge must have an equal

thickness.

4. Cut more than half of the diameter and then put the

felling wedge into the saw cut.

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. 56)

3. Make the lower horizontal notch cut. This will prevent

either the saw chain or the guide bar from being

pinched when the second notch is made.

4. Make the felling back cut (X) at least 50 mm (2 in)

higher than the horizontal notching cut. Keep the

felling back cut parallel to the horizontal notching cut

so enough wood is left to act as a hinge. Do not cut

through the hinge. The hinge wood keeps the tree

from twisting and falling in the wrong direction. (Fig.

57) (Fig. 58)

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,

plastic or aluminium to open the cut and let the tree

fall along the necessary line of fall. (Fig. 59)

6. When the tree begins to fall, remove the product

from the cut, stop the engine, put the product down,

then use the retreat path planned. Be alert for

overhead limbs falling and watch your footing. (Fig.

60)

To limb a tree

1. Use larger limbs to hold the log off the ground.

2. Remove small limbs in one cut. (Fig. 61)

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.

18 277 - 007 - 14.10.2019

• If the log is supported along its entire length, cut

from the top of the log (known as overbucking). (Fig.

62)

• If the log is supported on one end, cut 1/3 the

diameter from the underside of the log (known as

underbucking) . (Fig. 63)

• If the log is supported on both ends, cut 1/3 the

diameter from the top. Complete the cut by

underbucking the lower 2/3 of the log to meet the

first cut. (Fig. 64)

• If you buck a log on a slope, always stand on the

uphill side of the log. Cut through the log while you

maintain complete control of the product, then

release the cutting pressure near the end of the cut

while firmly gripping the rear handle and front

handle. (Fig. 65)

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. 75)

When you sharpen a cutting tooth there are four

important factors to remember:

• Filing angle.

(Fig. 76)

• Cutting angle.

(Fig. 77)

• File position.

(Fig. 78)

• Round file diameter.

(Fig. 79)

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 23

for information on the recommended

dimension of the file and gauge for the saw chain

installed on your product.

1. Make sure that the saw chain is correctly tensioned.

A slack chain will move sideways, making it more

difficult to sharpen correctly.

2. File all teeth on one side first. File the cutting teeth

from the inside face and reduce the pressure on the

return stroke.

3. Turn the product over and file the teeth on the other

side.

4. File all the teeth to the same length. When the length

of the cutting teeth is reduced to 4 mm (5/32") the

saw chain is worn out and must be replaced. (Fig.

80)

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

20

. 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.
