warranty will be voided if the machine is used in commercial, trade or industrial businesses or for the equivalent purposes.

KICKBACK

Kickback may occur when the nose or tip of the chain bar touches an object, or when the wood closes in and pinches the saw chain in the cut. If the bar tip contacts, it may cause an extremely fast reverse reaction, kicking the chain bar up and back towards the operator. Pinching the saw chain along the top of the chain bar may push the chain bar rapidly back towards the operator. Either of these reactions may cause you to lose control of the saw, which could result in serious personal injury. Do not rely exclusively upon the safety devices built into your saw. As a chainsaw user, you should take several

steps to keep your cutting jobs free from accident or injury.

■

NOTE! With a basic

understanding of kickback, you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents.

■

Keep a good ﬁrm grip on

the saw with both hands, the right hand on the rear handle, and the left hand on the front handle, when the engine is running. Use a ﬁrm grip with thumbs and ﬁngers encircling the chainsaw handles. A ﬁrm grip will help you reduce kickback and maintain control of the saw. Never let go of the Chainsaw.

■

Make sure that the area

in which you are cutting is free from obstructions. Do not let the nose of the chain bar contact a log, branch, or any other obstruction which could be hit while you are operating the saw.

CHAIN BRAKE MECHANICAL TEST

WARNING!

The purpose of the chain brake is to reduce the possibility of injury due to kickback; however, it cannot provide the intended measure of protection if the saw is operated carelessly.

Always test the chain brake before using your saw and periodically while on the job.

Your chainsaw is equipped with a chain brake that reduces possibility of injury due to kickback. The brake is activated if pressure is applied against the brake lever when, as in the event of kickback, the operator’s hand strikes the lever. When the brake is actuated, chain movement stops abruptly.

To test the chain brake

a. The Chain brake is DISENGAGED (chain can move) when

the BRAKE LEVER IS PULLED BACK AND LOCKED.

b. The chain brake is ENGAGED (the chain is locked)

when the brake lever is pushed forward. It should not be possible to move the chain.

NOTE! The brake lever should snap into both positions. If this is not the case do not use your saw. Contact the helpline immediately on 0345 605 2067.

4. Tighten the chain cover.

FILLING WITH ENGINE FUEL AND LUBRICATION OIL

This product is powered by a 2-Stroke engine and requires pre-mixing of petrol and 2-stroke oil.

Use a high quality 2-Stroke engine oil according JASO FC classic. Do not use automotive oil or 2-stroke outboard oil. DO NOT mix quantities larger than usable in a 30 day period.

FUEL MIXTURE: petrol: 2 Stroke engine oil = 40:1 ratio.

Note: there are two faces of this bottle one is 40:1, and the other is 25:1, please always use 40:1 for reference.

Using a funnel and keeping the bottle level, pour the petrol ﬁrstly in the left hand side (B) up to the required level and pour oil to (A) marking level. Shake vigorously to mix the petrol and oil prior to pouring into the tank(C).

17 AFTER SALES SUPPORT 0345 605 2067

PREPARE

Clean surface around fuel cap to prevent contamination. Loosen fuel cap slowly. Rest the cap on a clean surface. Carefully pour fuel into the tank. Avoid spillage. Prior to fastening the fuel cap, clean and inspect the seal located inside the fuel cap. Immediately replace fuel cap and hand tighten. Wipe up any fuel spillage.

NOTE! It is normal for smoke to be emitted from a new engine after ﬁrst use.

FILLING THE LUBRICATION OIL

Whenever you reﬁll the fuel tank with petrol you must also top up the level of chain oil in the chain oil reservoir.

Use special chainsaw oil to lubricate the saw chain.

NOTE! Most stores will sell acceptable oil under the name “Chainsaw chain oil”.

Important! The fuel mix is added into fuel tank(C), chain lubrication oil is ﬁlled into oil reservoir(D). Seal one cap prior to removing the second cap. If you put the ﬂuid into the wrong tank seek assistance from an expert immediately.

CHECK CHAIN BRAKE

This machine is equipped with a chain-brake that will immediately disable the chain upon the occurrence of kickback during cutting. The brake is automatically operated by inertia forces, which act on the weight ﬁtted inside the front guard. This brake can also be operated manually with the front guard pushed forward to the guide bar. To disengage the chain-brake, pull it back until it touches the front handle.

a= brake disengage

b= brake engage

IMPORTANT! Be sure to conﬁrm brake operation

every time you use the machine and periodically during the period of use.

HOW TO CONFIRM IF THE CHAIN BRAKE IS FUNCTIONING CORRECTLY

1. Turn off the engine and leave until cold.

2. With the chainsaw on a ﬂat surface and the chain tensioned correctly, engage the chain-brake by pushing it forward until an audible click is heard. Then, wearing protective gloves, attempt to move the chain by hand in the direction of normal rotation if this is not possible the chain brake has been engaged. If the brake is engaged when the chain is rotating at high speed for extended periods of time this can cause damage to the clutch or for it to fail completely. When the brake is activated whilst cutting, immediately release it having ﬁrst released the throttle lever and set the chainsaw swtich to “O”.Call service center to for more help.

SAWING

WARNING! Before proceeding to your job, read the

“Safety instructions” section. It is recommended to ﬁrst practice sawing easy logs. This also helps you get accustomed to your unit. Always follow the safety regulations. The chainsaw must only be used for cutting wood. It is forbidden to cut other types of material. Vibrations and kickback will vary with materials other than wood and the requirements of the safety regulations would not be met. Do not use the chainsaw as a lever for lifting, moving or splitting objects. Do not lock it over ﬁxed stands. It is strictly forbidden to attach any accessories to this product other than those supplied by the manufacturer.

It is not necessary to force the saw into the cut. Apply only light pressure while running the engine at full throttle.

If the saw chain gets caught in the cut, do not attempt to force it out, but use a wedge or a lever to enlarge the cut, freeing the saw.

FELLING A TREE

WARNING! You should have received training from a

suitable person before attempting to fell a tree.

When you fell a tree, be sure to warn anyone in close proximity of the danger

1. Decide the felling direction considering the wind, lean of

the tree, location of heavy branches, ease of job after felling and other factors.

2. While cleaning the area around the tree, arrange a good

foothold and retreat path.

Periodically check and clean the cooling system and the cylinder ﬁns with a brush after removing the cylinder cover, the air cleaner and the recoil case. When installing the cylinder cover and the cooling system, make sure that switch wires and grommets are positioned correctly in place.

NOTE! Be sure to unblock the air intake hole.

MAINTENANCE

MAINTENANCE OF THE SAW CHAIN AND CHAIN BAR

NOTE! It is very important for smooth and safe

operation to always keep the cutters always sharp.

The cutters need to be sharpened when:

1. Sawdust becomes powder-like.

2. Cutting requires extra force.

3. The chainsaw does not cut straight and clean.

4. Vibration increases.

5. Fuel consumption increases.

MAINTENANCE

Chain Bar

1. Reverse the bar occasionally to prevent partial wear.

2. The bar rail should always have parallel internal faces (see diagram). Check for wear of the bar rail. Apply a ruler to the bar and the outside of a cutter. If a gap is observed between them, the rail is normal. Otherwise, the bar rail is worn. Such a bar needs to be corrected or replaced.
