Safety The circular metal saw is designed and manufactured to saw cold metals, cast materials and other plastic materials that are not harmful to health and do not generate dust. The circular metal saw must not be used on wood. The pieces to be cut need to be of a shape that will allow them to be securely attached in the work holder vice and ensure that the piece does not come loose when it is being sawed.
Safety WARNING! THE CIRCULAR METAL SAW MAY ONLY BE USED WITH THE SAFETY DEVICES ACTI- VATED. Disconnect the circular metal saw whenever you detect a failure in the safety devices or when they are not fitted! All additional installations carried out by the operator must incorporate the prescribed safety devices.
Safety The user must Obligations • have received training in operation of the circular metal saw, of the user • know the function and principle of operation, • before the machine is first used have read and understood the operating manual, be familiar with all safety devices and regulations.
Safety • protective goggles or face guard, • protective gloves, • safety shoes with steel caps, • ear protection. Before starting work, make sure that the prescribed individual protection gear is available at the workplace. CAUTION! Dirty or contaminated personal protection gear can cause disease. Clean your personal protection gear after each use, regularly, at least once a week.
Safety 1.10 Safety during maintenance Report and Inform operating staff in good time of any repair and maintenance work. document Report all safety-relevant changes or performance details of the circular metal saw. Document any changes all changes, have the operating manual changed accordingly and train the machine operators. 1.10.1 Disconnecting the circular metal saw and making it safe Unplug the circular metal saw from the mains before beginning any maintenance or repair work.
Safety 1.11 Accident report Inform your superiors and Colovos Company immediately in the event of accidents, possible sources of danger and any actions which almost led to an accident (near misses). These near misses can have many causes. The sooner they are notified, the faster the causes can be eliminated. INFORMATION In the description of the execution of work with and on the circular metal saw, we highlight the dangers specific to that work.

Technical data Operating material CS 250 Spindle of the machine vice Commercial heavy grease Plain bearing Commercial heavy grease Blank steel parts e.g. machine oil (Mobil oil, Fina, ...), motor oil, motor oil is acid-, stain- and resin-free. Emissions The level of noise (emission) emitted by the circular metal saw is less than 80 dB(A).
Assembly Assembly INFORMATION The circular metal saw comes pre-assembled. Extent of supply When the machine is delivered, immediately check that the circular metal saw has not been damaged during shipping and that all components are included. Also check that no fastening screws have come loose.
Assembly Observe the preventing of accidents issued by your association for the prevention of occupational accidents and safety in the workplace or other inspection authorities. Hold the loads properly. Never walk under suspended loads! Storage ATTENTION! Improper storage may cause important parts to be damaged or destroyed. Store packed or unpacked parts only under the intended environmental conditions.
The mains plug of the circular metal saw must be freely accessible. 3.4.2 Fasten the substructure of the circular metal saw CS 250 on the floor Fasten the substructure on the floor with shear connector screws M10. Illustration: 3-1: Machine substructure CS 250...
Assembly 3.4.3 Mount the saw on the machine substructure ATTENTION! Danger of crushing and overturning. Proceed with caution during the work described below. CAUTION! The circular metal saw needs to be mounted on the machine sub- structure by at least two persons.
Assembly 3.4.6 Mount the saw blade Mount your saw blade “Mounting and replacing the saw blade“ on page 39 First use WARNING! Personnel and equipment may be endangered if the circular metal saw is first used by inexpert staff. We do not take liability for any damage caused by incorrect commissioning. 3.5.1 Checking Check the following.

Operation Sawing of angles The circular metal saw can be turned from -45° to 45° in order to allow angular saw cuts. Angle scale Locking lever cutting angle Illustration: 4-9: Setting of angle cut CAUTION! Make sure that the saw is clean and free of chips in the slewing area before adjusting it. Loosen the locking lever.
Operation Cooling ATTENTION! Damage to the pump in the event of dry running. When the circular metal saw is switched on the coolant pump is switched on. The pump is lubricated by the coolant. Do not start up the pump without coolant. Turn the dosing stop valve in direction of the coolant hose until the coolant penetrates.
