Frequently Asked Questions - M1Y-140-900A Cotech

How do I adjust the cutting depth on the Cotech M1Y-140-900A?

Loosen the lock screw for depth adjustment, lower the foot plate to the desired depth, then tighten the lock screw securely. Ensure the saw is unplugged before adjusting.

How do I change the saw blade?

Unplug the saw. Lock the blade using the blade lock. Use the Allen key to unscrew the lock screw (turn in direction of blade rotation). Push back the blade guard and hold with maneuvering lever. Remove the flange nut and old blade. Install new blade (140x16mm) in reverse order. Adjust riving knife if needed.

What should I do if the saw does not start?

Check that the mains outlet is live. If the problem persists, the carbon brushes may be worn or there may be a short circuit or defective switch. Contact customer service for repairs.

Why is the saw running slowly?

A dull or damaged saw blade can cause slow operation. Sharpen or replace the blade. Also, feed the saw with less force to avoid overloading. If the motor is overheated, allow it to cool.

How do I adjust the riving knife?

Unplug the saw. Loosen both screws holding the riving knife. Push the blade guard back and hold with the maneuvering lever. Adjust the riving knife so it is max. 5 mm from the saw blade and the blade does not protrude more than 5 mm below the knife edge. Tighten screws. Ensure alignment.

Can I use this saw for plunge cutting?

Yes, but only for special operations. The lower blade guard must be moved aside using the handle, and the riving knife should be detached if needed (re-attach after). Always follow safety instructions for plunge sawing.

What safety equipment should I wear?

Always wear safety glasses, hearing protection, and a dust mask. Use slip-resistant shoes and avoid loose clothing or jewelry. Hold the saw firmly with both hands.

How do I clean and maintain the saw?

Keep ventilation openings free of debris. Clean the exterior with a soft cloth and mild detergent. Do not use solvents. Regularly check the blade, guard, and riving knife for damage.

What is the maximum cutting depth at 45°?

The saw depth at 90° is 46 mm. At 45°, the maximum cutting depth is less; it is not explicitly stated but typically around 30-35 mm. Adjust the depth accordingly.

Where can I get replacement parts or service?

Contact Clas Ohlson customer service (see manual for local contact details). Only use original spare parts to ensure safety. Repairs should be done by qualified personnel.

1. Safety

Warning! Read all the instructions. Failure to adhere to the following instructions may lead to electric shocks, fires and/or serious injury. The term “electrical hand tools” in the warning text below is referring to your mains operated or battery operated hand tool. SAVE THE INSTRUCTIONS.

1.2 General safety instructions

1) The work space

a) Keep the work space clean and well illuminated. Cluttered and poorly lit areas invite accidents.
b) Do not use electrical hand tools in explosive environments, i.e. nearby flammable liquids, gas or dust. Electrical hand tools generate sparks that could easily ignite dust or fumes.
c) Keep away from children and other spectators while using the electrical hand tool. Distractions can make you lose your concentration and control.

2) Electrical safety

a) The electrical hand tool's plug must fit correctly in the wall socket. Never modify the plug in any way. Never use an adaptor together with earthed electrical hand tools. Unmodified plugs and suitable wall sockets decrease the risk of electric shock.
b) Avoid body contact with earthed objects, such as pipes, radiators, ovens or refrigerators. There is an increased risk of electrical shock if your body is earthed.
c) Do not expose the electrical hand tool to rain or other wet conditions. If water gets inside an electrical hand tool it increases the risk of electrical shock.
d) Do not misuse the lead. Never use the lead to carry, drag or pull the plug out of the wall socket. Keep the lead away from heat, oil, sharp edges and movable parts. Damaged or tangled leads increase the risk of electrical shock.
e) When you use an electrical hand tool outdoors; use an extension cord suitable for this purpose. Use of an extension cord for outdoor use decreases the risk of electrical shock.

3) Personal safety

a) Pay attention to what you do and use common sense when using electrical hand tools. Never use an electrical hand tool if you are tired or under the influence of drugs, alcohol or medication. One moment of not paying attention while using an electrical hand tool may result in serious injury.
b) Use protective equipment. Always use safety glasses. Using protective equipment such as a face mask, slip resistant protection shoes, a helmet and ear plugs when needed decreases the risk of injury.
c) Avoid unexpected start. Make sure that the switch is set to OFF before you connect the device to the wall socket. Never carry an electrical hand tool with one finger on the trigger or never connect the hand tool to a wall socket when the switch is set to ON, since it may result in injury.
d) Remove all service tools/keys before switching on the hand tool. A forgotten service tool on a rotating part of the electrical hand tool may result in injury.
e) Do not overreach. Make sure you stand steady and well balanced at all times. This gives better control in unexpected situations.
f) Wear suitable clothing. Do not wear loose fitting clothes or jewellery. Keep hair, clothes and gloves away from movable parts. Loose fitting clothes, jewellery or long hair could get caught in movable parts.
g) If the equipment for suctioning or collecting dust is available make sure it is connected and used properly. Using technical aids may reduce dust related hazards.

4) Use and maintenance of the electrical hand tools

a) Do not overdrive the hand tool. Use a hand tool suitable for the work you are to perform. At the correct rate of feed, the correct tool will carry out the work better and more safely.
b) Never use the electrical hand tool if the switch does not work properly to turn on and shut off the tool. All electrical hand tools that can not be operated by the switch are dangerous and must be repaired.
c) Unplug the lead from the wall socket before making any adjustments, changes of accessories or storing the electrical hand tool away. These precautions reduce the risk of unexpected start of the electrical hand tool.
d) Store electrical hand tools that are not being used out of reach from children. Do not let people unfamiliar with the electrical hand tool or its instructions use it. Electrical hand tools can be dangerous if they get into the hands of inexperienced users.
e) Maintenance of electrical hand tools. Check if something is incorrectly set, if movable parts are getting jammed, or parts are broken or something else that might cause the electrical hand tool to malfunction. If something is damaged it must be repaired before use. Many accidents are caused by poorly maintained electrical hand tools.

f) Keep the tools sharp and clean. Properly maintained cutting tools with sharp blades are less likely to jam and are easier to control.
g) Use the electrical hand tool, accessories and such according to the instructions and in a way suitable for the type of electrical hand tool used. Using the electrical hand tool for work other than that for which it is intended could result in a dangerous situation.

5) Service

a) Repairs and service should only be performed by qualified persons, and only with original spare parts. This guarantees the safety of the electrical hand tool.

Specific Safety Requirements for Circular Saws

DANGER:

a) Keep hands at a safe distance from the saw blade. Keep your other hand on the front handle or on the housing. If you are holding the saw with both hands you cannot cut your hand.
b) Do not reach under the workpiece. The blade guard will not protect you from the blade underneath the workpiece.
c) Adjust the cutting depth to suit the thickness of the workpiece. Less than the length of one of the saw blade's teeth should be visible under the workpiece.
d) Do not hold the workpiece in your hands or across you leg. Fasten the workpiece to a stable surface. It is important that the workpiece is correctly supported to minimise the risk of personal injury, to prevent the saw blade from binding and to prevent you from losing control of the saw.
e) Hold the electrical hand tool by its insulated handles whenever performing tasks where there is a risk of the saw cutting through hidden power cables or its own power cable. Contact with a live wire can lead to the metallic parts of the electrical hand tool becoming live and giving the user an electric shock.
f) When rip sawing, a parallel fence or straight edge guide should be used. This will improve the precision of the sawing and reduce the chances of the saw blade binding.
g) Always use saw blades of the correct size and shape (diamond shaped or round). Saw blades that do not fit the saw properly will rotate eccentrically leading to loss of control over the saw.
h) Never use damaged or faulty washers or bolts. The washers and bolts for the saw blade are specially designed to achieve maximum performance and safety.

Additional Safety Instructions for all Saws

Reasons for kickback and preventing kickback:

• Kickback is a sudden reaction to a pinched, jammed or incorrectly aligned saw blade which causes the saw to jump back violently out of the workpiece towards the user.
• When the saw blade binds because the kerf behind the blade is closed, the blade stops and the unit is ejected back towards the user.
• If the saw blade is twisted or distorted in the saw cut the teeth at the back of the saw blade can fasten in the workpiece and eject it towards the user.

Kickback is caused by the saw being used incorrectly, for the wrong purpose or under the wrong conditions and can be avoided by taking the following precautions:

a) Hold the saw firmly in both hands and in such a way that you can parry any kickbacks. Stand to the side of saw blade, not in line with it. A kickback can cause the saw to jump backwards but it can be controlled if certain precautions are taken.
b) When the saw blade jams, or if the sawing process is interrupted for some reason, switch the power off and hold the saw still until the blade has completely stopped. Never attempt to withdraw the saw from the workpiece when the blade is rotating, as this could cause a kickback. Examine and take the necessary measures to minimise the risk of blade jamming.
c) When restarting a saw in a workpiece, centre the saw blade in the saw cut and make sure that the teeth of the blade are not touching the material. If the saw blade has jammed it could wander upwards or be ejected from the workpiece when the saw is restarted.
d) Support large boards to reduce the risk of the saw blade binding or of the saw kicking back. Large boards tend to bow under their own weight. The boards need to be supported on both sides, near the saw cut and near the edge of the board.
e) Do not use blunt or damaged saw blades. Blunt or incorrectly set saw blades can produce saw cuts that are too narrow, producing too much friction and causing the saw blade to bind or the saw to kickback.
f) The cutting depth and angle adjusters must be locked in place before sawing begins. If any of the saw blade setting adjusters moves during cutting the blade could jam or the saw could kickback.
g) Be especially careful when plunge sawing in walls or objects where it is not possible to see what one is sawing. The saw blade could cut into objects that could cause kickbacks.

Safety Instructions for Saws Fitted with Inner Blade Guard

a) Make sure that the lower blade guard is properly closed before each use.
Do not use the saw if the lower blade guard does not move freely and close immediately. Never clamp or bind the lower blade guard in the open position. If the saw is accidentally dropped the lower blade guard can be bent. Lift the lower blade guard using the handle and make sure that it can move freely without touching the saw blade or any other part of the saw in any of the saw's cutting angles and depths.
b) Make sure that the spring on the lower blade guard works. If the guard or spring does not work properly it must be repaired before the saw is used. The lower guard can stick due to damaged parts, sticky deposits or a build-up of sawdust.
c) The lower blade guard may only be moved to the side for special operations such as plunge sawing and compound sawing. Move the lower guard to the side using the handle and as soon as the saw blade makes contact with the material the lower guard must be released. For all other sawing the lower guard must work automatically.
d) Always make sure that the lower blade guard is covering the blade before laying the saw on a bench or the floor. An uncovered rotating saw blade can cause the saw to move backwards and saw through everything in its path. Bear in mind that it takes time for the saw blade to come to a stop after the power switch has been released.

Additional Safety Instructions for all Saws Fitted with Riving Knives

a) Use a riving knife compatible with the saw blade being used. In order for the riving knife to work it must be thicker than the saw blade but thinner than the kerf of the saw blade.
b) Adjust the riving knife according to the directions in this instruction manual. Incorrect distance, incorrect position and alignment can lead to the riving knife not preventing kickbacks.
c) Always use the riving knife except when plunge sawing. The riving knife must be reattached if it is detached for plunge sawing. The riving knife could get in the way when plunge sawing and cause kickback.
d) In order for the riving knife to work it must pass through the workpiece. The riving knife cannot prevent kickback on short saw cuts.
e) Do not use the saw if the riving knife is bent. Even a small defect can slow the closing time of a safety guard.

• Tie the workpiece down if it is not held in place by its own weight.
• Use a dust extractor when using the circular saw.
• Always wear a dust mask when using the circular saw.
• Use only those saw blades designed to be used with this circular saw.
• Always wear ear defenders when using the circular saw.
• Grinding/Cutting discs must not be used with this circular saw.
• New plugs or mains leads must only be fitted by qualified personnel.
