General working instructions
WARNING! This section describes basic safety directions for using a wall saw. This information is never a substitute for professional skills and experience. If you get into a situation where you feel unsafe, stop and seek expert advice. Contact your dealer, service agent or an experienced user. Do not
attempt any task that you feel unsure of!
• All operators shall be trained in the use of the machine. The owner is responsible for ensuring that the operators receive training.
• Check that the blade guard is not damaged and that it has been fitted correctly.
• Never use blades other than original blades designed for the machine. Check with your Husqvarna dealer to see which blades are best suited for your usage.
• Never use a damaged or worn blade.
• Never mount or dismount the blade or blade guard without first switching off the hydraulic unit and disconnecting the hydraulic hoses running to the saw unit.
• Never cut without using the blade guard.
• Check that the blade is not in contact with anything when the machine is started.
• Remain at a distance from the blade when the engine is running.
• Water cooling must always be used. This cools the blades and increases their life and prevents dust build-up.
• Check that all couplings, connections and hydraulic hoses are in full working order.
• Keep the hydraulic hoses and couplings free from dirt.
• Do not misuse hoses.
• Do not use hoses that are distorted, worn or damaged.
• Check that the hoses are connected correctly to the machine and that the hydraulic couplings lock as intended before pressurizing the hydraulic system. The couplings are locked by turning the outer sleeve on the female coupling so that the slot moves away from the ball.
• Never use the hydraulic hoses to lift the saw.
• Check the machine, couplings and hydraulic hoses daily for leakage. A rupture or leak can cause a ”hydraulic fluid injection” in the body or result in other serious physical injury.
• Never disconnect the hydraulic hoses without first shutting off and disconnecting the hydraulic unit and ensuring the motors have stopped completely.
• Do not exceed the specified hydraulic fluid flow or pressure for the tool being used. Excessive pressure or flow can result in rupturing.
• Hoses that are marked and approved as electrically non conductive must be used when using hydraulic tools on or in the vicinity of electrical cables. The use of other types of hoses can result in serious physical injury or even death.
• Run the hydraulic system until it reaches its operation temperature of 30°C before starting to saw, to reduce return pressure and other wear.
• Clearly mark out all cuts to be made before you start sawing, plan these so they can be carried out without danger to persons or the machine.
• Firmly secure or anchor concrete blocks before cutting. The heavy weight of cut material can cause extensive damage if it is not moved under controlled conditions.
• Always check the back of the wall where the blade comes out when cutting through. Secure, cordon off and make sure that no people can be injured or materials damaged.
• Always check and mark out where gas pipes are routed. Cutting close to gas pipes always entails danger. Make sure that sparks are not caused when cutting in view of the risk of explosion. Remain concentrated and focused on
the task. Carelessness can result in serious personal injury or death.
• Make sure that no pipes or electrical cables are routed in
the area to be cut.
• Check that electrical cables within the working area are not live.
• Never leave the machine unsupervised with the engine running.
• Never saw in such a way that you cannot easily reach the emergency stop on the hydraulic unit or on the remote control. See hydraulic unit manual.
• Make sure that there is always another person close at hand when you use the machines, so that you can call for help if an accident should occur.
• People that need to be in close proximity of the machine must wear hearing protection as the sound level when cutting exceeds 85 dB(A).
• Make sure that no people or animals come closer than 4 m (15 ft) when the machine is running.
• Do not use the machine in bad weather, such as dense fog, rain, strong wind, intense cold, etc. Working in bad weather is tiring and can lead to dangerous conditions, e.g. slippery surfaces.
• Ensure that the working area is sufficiently illuminated to create a safe working environment.
• Always ensure you have a safe and stable working position.
• Observe care when lifting. You are handling heavy parts, which implies the risk of pinch injuries or other injuries.
WARNING! Never use a blade for any other materials than that it was intended for.
Operating saw blades at rotational speeds greater than those recommended by the manufacturer can cause blade damage and possibly subsequent injury. See the Technical data section.
Basic working techniques
• Always start by cutting a pilot cut. This is done by feeding the blade 3-7 cm (1,2”-2,8”). Now make the pilot cut. The cut should not be made at maximum speed, but with care in order to obtain a straight cut and with that a basis for the next cut. The cutting arm allows blades up to 1 000 mm (40”) to be used as the start blade. It is, however, recommended to start cutting with an 800 mm (31.5”) blade.
• When the pilot cut is finished, a deeper cut can be made. The depth of these is determined from instance to instance and depends on factors such as hardness of the concrete, existence of reinforcing bar, etc. Max. diameter
of the blade for deeper cuts is 1,600 mm (63”).
• If you change blades to cut deeper in the same cut, make sure the thickness of the blade matches the width of the groove.
• Let the machine work without forcing or pressing the blade.
• Firmly secure or anchor concrete blocks before cutting.
The heavy weight of cut material can cause extensive damage if it is not moved under controlled conditions.
Cutting of block.
• First make the lower horizontal cut. Now make the upper horizontal cut. Finish with the two vertical cuts.
• If the upper horizontal cut is made before the lower horizontal cut, the work piece will fall on the blade and jam it.
• When making the last cut, the saw should be mounted on an adjacent fixed wall.
• As the rail is symmetrical, the saw unit can be turned to make a new cut on the other side of the rail. In this way a cut piece is obtained that is in an easily handled size, making it easier to remove from the workplace.
• Since the blade rotation direction can be selected, the water spray from the blade can also be selected regardless of how the saw is turned on the rail. |
