Watch tension carefully for the first half hour of use and periodically throughout the life of the chain, readjusting as required when the chain and bar are cool to the touch. NEVER tension the chain when it is hot.

Using the Chainsaw

For ‘first-time’ users of this type of product, we recommend that introductory training be undertaken from an experienced person before use.

Personal Protective Equipment

The following Personal Protective Equipment (PPE) available from your local CLARKE dealer has been designed for use with chainsaws.

• A safety helmet with a mesh visor.
• Ear defenders.
• Specialist chainsaw gloves.
• Trousers or chaps suitable for chainsaw use (they contain a clogging material which stops the chain if cut).
• Safety boots with toe and shin protection.
• Close-fitting hi-visibility jacket.

Grip

Always grip the tool with both hands. Grasp the front handle with the left hand and the rear handle with the right, as shown. Wrap the fingers over the top of the handle with the thumb below the handle.

Footing

Stand with both feet on solid ground with weight evenly spread between them, as shown.

Starting the Chainsaw

1. Make sure the chain brake is not engaged.
2. Grasp the front and rear handles firmly.
3. Press and hold the trigger lockout with the thumb (1).
4. To start the saw, squeeze the trigger switch (2), as shown.
5. There is no need to continue to press the trigger lockout. It will remain disengaged until the trigger is released.

Stopping the Chainsaw

Release the trigger switch to stop the chainsaw.

Testing the Brake

To check brake operation

1. Place the saw on a firm, flat surface with no obstructions to the chain.
2. Start the saw briefly.
3. Keep the left hand on the front handle and roll the left wrist to move the front hand guard forward to manually activate the chain brake, as shown.
4. Release the trigger switch.
5. Return the front hand guard to operating position.

Power Cord

1. Specifically labeled for outdoor use.
2. Of a wire size heavy enough to carry the current the full length of the cable, according to the table below.

Select the gauge of extension cord based on the desired length and the electrical specifications found on the product label or in the specification section of this manual.

Cord Length (M) & Min. Diameter Wire Size

• 0 – 15: 1.6277mm
• 16 – 30:  2.0525mm

Make sure the insulation is free of cracks and that the plugs are undamaged.

Using the Strain Relief

It is important to use the strain relief bracket for two reasons

1. It saves wear on both the power cord and the extension cord and their plugs.
2. It prevents the chainsaw frog from unplugging from the extension cord.

To use the strain relief bracket, bend the extension cord into a U shape and put it through the hole in the rear handle. Slide the loop of cord over the hook and tug lightly until snug, as shown.

Cutting, Pruning, Felling, Limbing, and Bucking

Practice cutting logs on a sawhorse or cradle until you become comfortable operating the saw. To get the best performance and to operate the saw safely, follow these instructions.

1. Observe all applicable national and local rules and regulations for cutting.
2. Take frequent breaks to reduce the risk of injury.
3. Before beginning to cut, make sure the saw chain is properly tensioned and the chain is sharp.
4. The pressure required to make cuts increases noticeably.
5. Wood chips coming off the chain are very fine or dust-like.
6. Assume the proper cutting grip and stance in front of the wood with the saw turned off. Press the trigger switch. Let the chain reach full speed before beginning the cut.
7. Begin cutting by lightly pressing the guide bar against the wood. Use only light pressure and let the saw do the work.
8. Maintain a steady speed throughout the cut, releasing pressure just before the end of the cut.
9. Know the location of the cord at all times to avoid trip hazards and avoid cutting the cord.
10. Know the location of the tip of the bar at all times and avoid contact with other objects.
11. If the saw stops suddenly when cutting, remove the saw from the cut, then resume cutting using lighter pressure on the workpiece.

Limbing A Tree

Limbing is removing the branches from a fallen tree.

• When limbing, leave large lower limbs to support the log off the ground.
• Remove the small limbs in one cut.
• Branches under tension should be cut from the bottom up to avoid binding the chainsaw, as shown.

Bucking A Log

Bucking is cutting a log into lengths. It is important to make sure the footing is firm and the weight is evenly distributed on both feet. When possible, the log should be raised and supported by the use of limbs, logs, or chocks.

1. When the log is supported along its entire length, cut from the top (overbuck), as shown.
2. When the log is supported on one end, cut 1/3 the diameter from the underside (underbuck), then make the finished cut by overbucking to meet the first cut, as shown.
3. When the log is supported on both ends, cut 1/3 of that diameter from the top overbuck, then make the finished cut by underbucking the lower 2/3 to meet the first cut, as shown.
4. When bucking on a slope, always stand on the uphill side of the log, as shown.
5. Don’t let the chain contact the ground.
6. After completing the cut, wait for the saw chain to stop before you move the chainsaw.
7. Always stop the motor before moving from tree to tree.

Prevention Of Kickback

1. Maintain a firm grip, with thumbs and fingers encircling the chainsaw handles, with both hands on the saw, and position your body and arm to allow you to resist kickback forces. Kickback forces can be controlled by the operator if proper precautions are taken. DO NOT let go of the chainsaw.
2. DO NOT overreach and DO NOT cut above shoulder height. This helps prevent unintended tip contact and enables better control of the chainsaw in unexpected situations.
3. Only use replacement bars and chains specified by the manufacturer. Incorrect replacement bars and chains may cause chain breakage and/ or kickback.

Kickback Safety

1. Chain Brake. This chainsaw comes equipped with a chain brake, which stops both the motor and the motion of the chain when kickback occurs. The chain brake can be activated by the forward motion of the front hand-guard as the saw rotates backward during kickback; it can also be activated by the inertial forces generated from a kickback event.
2. Chain. This chainsaw comes equipped with a saw chain that meets the reduced kickback performance requirements of ISO 9518.
3. Bar. This saw comes equipped with a reduced kickback guide bar that has a small radius nose. Smaller radius noses have less potential for kickback..

Electrical Connections

• The Blue wire must be connected to the terminal which is marked N or coloured Black.
• The Brown wire must be connected to the terminal which is marked L or coloured Red.
• We strongly recommend that this machine be connected to the mains supply via a Residual Current Device (RCD). If in any doubt, consult a qualified electrician. DO NOT attempt any repairs yourself.
