GENERAL SAFETY PRECAUTIONS / ASSEMBLY

If the chain lubrication system is still not working after carrying out the above checks and associated measures you should contact your servicing dealer.

Chain drive sprocket

The clutch drum is fitted with a Spur sprocket (the chain sprocket is welded on the drum).

Regularly check the degree of wear on the drive sprocket. Replace if wear is excessive. Replace the drive sprocket whenever you replace the chain.

Checking wear on cutting equipment

Check the chain daily for:

•Visible cracks in rivets and links.

•Whether the chain is stiff.

•Whether rivets and links are badly worn.

Replace the saw chain if it exhibits any of the points above.

We recommend you compare the existing chain with a new chain to decide how badly the existing chain is worn.

When the length of the cutting teeth has worn down to only 0.16 inch (4 mm) the chain must be replaced.

Bar

Check regularly:

•Whether there are burrs on the edges of the bar. Remove these with a file if necessary. (13)

•Whether the groove in the bar has become badly worn. Replace the bar if necessary. (14)

•Whether the tip of the bar is uneven or badly worn. If a hollow forms on the underside of the bar tip this is due to running with a slack chain.

•To prolong the life of the bar you should turn it over daily.

WARNING! Most chain saw accidents

!happen when the chain touches the operator.

Wear personal protective equipment. See instructions under the heading Personal protective equipment.

Do not tackle any job that you feel you are not adequately trained for. See instructions under the headings Personal protective equipment, How to avoid kickback, Cutting equipment and General working instructions.

Avoid situations where there is a risk of kickback. See instructions under the heading Machine′s safety equipment.

Use the recommended protective equipment and check its condition. See instructions under the heading General working instructions.

Check that all the chain saw safety features are working. See instructions under the headings General working instructions and General safety precautions.

Fitting the bar and chain

WARNING! Switch off the engine before

!carrying out any checks or maintenance. The stop switch automatically returns to the start position. In order to prevent unintentional starting, the spark plug cap must be removed from the spark plug when assembling, checking and/or performing maintenance.

Always wear gloves, when working with the chain, in order to protect your hands from injury.

Check that the chain brake is in disengaged position by moving the front hand guard towards the front handle.

Remove the bar nuts and remove the clutch cover (chain brake). Take off the transportation ring. (A)(15)

Fit the bar over the bar bolts. Place the bar in its rearmost position. Place the chain over the drive sprocket locate it in the groove on the bar. Begin on the top edge of the bar.

(16)

Make sure that the edges of the cutting links are facing forward on the top edge of the bar.

Fit the clutch cover (chain brake) and locate the chain adjuster pin in the cut-out in the bar. Check that the drive links of the chain fit correctly on the drive sprocket and that the chain is in the groove on the bar. Tighten the bar nuts finger-tight. (17)

Tension the chain by turning the chain tensioning screw clockwise using the combination spanner. The chain should be tensioned until it does not sag from the underside of the bar. See instructions under the heading Tensioning the chain. (18)

The chain is correctly tensioned when it does not sag from the underside of the bar, but can still be turned easily by hand. Hold up the bar tip and tighten the bar nuts with the combination spanner. (19)

When fitting a new chain, the chain tension has to be checked frequently until the chain is run-in. Check the chain tension regularly. A correctly tensioned chain ensures good cutting performance and long life. (20)

235, 240 specifications

The Husqvarna 235 and 240 chainsaws are compact, lightweight power tools designed for homeowners and occasional users seeking reliability and performance. Known for their ease of use and versatility, both models are ideal for tasks such as pruning, cutting firewood, and clearing small trees.

One of the main features of the Husqvarna 235 and 240 is their X-Torq engine technology. This innovation reduces fuel consumption by up to 20% while also cutting emissions by approximately 75%. This not only makes the chainsaws environmentally friendly but also saves users on fuel costs over time. The engine's design also enhances torque, providing ample power for cutting through wood efficiently.

Both models come equipped with an inertia-activated chain brake, enhancing safety by preventing unwanted chain movement in case of a kickback. The chain brake is a critical feature for novice users, promoting confidence while operating the chainsaw. This focus on safety extends to the easy-to-reach throttle lockout and combined choke/stop control, allowing for simpler starting procedures.

The Husqvarna 235 and 240 feature an adjustable oil pump, which enables users to control the oil flow to the chain according to their specific needs. This functionality not only prolongs the life of the chain and bar but also helps maintain cutting performance, ensuring smoother operation and reduced wear.

These chainsaws also have ergonomic designs, with comfortable handles that minimize vibrations and allow for prolonged use without fatigue. The lightweight structure makes them easily maneuverable, which is particularly beneficial for tasks that require precision casing or reaching difficult areas.

Another noteworthy characteristic is the Tool-less chain tensioning system. This feature allows users to adjust the chain tension quickly and without the need for additional tools, simplifying maintenance and enhancing user experience.

Overall, the Husqvarna 235 and 240 chainsaws are excellent choices for homeowners seeking reliable, efficient, and easy-to-use tools for light to moderate cutting tasks. With advanced features like X-Torq technology, safety mechanisms, and user-friendly designs, they represent a valuable addition to any gardening or outdoor toolkit.
