Make sure fire extinguishers are available for use as there is a risk of fire due to flying sparks and the use of flammable fuel. Do not use reducing sleeves. Use of the wet cutting method is preferable in order to reduce the amount of dust produced when cutting mineral materials and asphalt. Avoid skin contact with the slurry created when using the wet cutting method. Dust from materials such as paint containing lead, some types of wood, minerals and metal can be harmful to health.
2.5 ▶ ▶ ▶ ▶ ▶ ▶ ▶ ▶ ▶ ▶ ▶ ▶ 2.6 ▶ ▶ ▶ ▶ ▶ ▶ ▶ ▶ ▶ 2.7 Cutting work using cutting discs Use only cutting discs with a rated maximum permissible speed that’s at least as high as the highest spindle speed.

3.7 Saw blade brake DSH 600-X The product is equipped with an integrated saw blade brake to increase operator safety. The saw blade is braked to a standstill in a maximum of 10 seconds after the throttle safety grip is released. Releasing the throttle safety grip when the tool is running at full speed causes the tool to flick forward slightly because of the braking torque. So hold the tool firmly with both hands on the grips provided. 3.

5.1.3 Mixing fuel The engine will suffer damage if run with fuel mixed in the wrong ratio or with unsuitable oil. Use a mixing ratio of 1:50. This corresponds to 1 part good-quality two-stroke oil that complies with the API-TC specification and 50 parts gasoline (e.g. 100 ml oil and 5 liters of gasoline mixed in a suitable canister). 1. 2. 3. 4. Pour the required quantity of two-stroke oil into the fuel canister. Then fill the gasoline into the fuel canister. Close the fuel canister.
1. Insert the locking pin in the hole in the drive belt cover and turn the cutting disc until the locking pin engages. 2. Release the securing screw by turning the screw counterclockwise with the wrench and then remove the screw and washer. 3. Remove the locking pin. 4. Remove the clamping flange and the cutting disc. 5. Check that the diameter of the arbor hole in the cutting disc to be fitted matches the centering collar of the cutting disc mounting flange.
7. Select one of the following alternatives. ▶ Use only the large flange to secure the abrasive cutting disc. ▶ Use the small flange with diamond cutting discs in order to utilize the full cutting depth. 8. Place the cutting disc with centering collar on the drive arbor and check that the direction of rotation is correct. ◁ The direction-of-rotation arrow on the cutting disc must match the direction of rotation indicated on the tool. 9.
5.2.3 Fitting the water pump (accessory) 1. Release the three pump cover retaining screws, remove the parts and store the pump cover in a safe place. The pump cover must be fitted if the tool is used without the water pump. 2. Hold the water pump in position and turn the cutting disc slightly to bring the splines of water pump and clutch bell into alignment so that the splines engage. ◁ The position is keyed so it is not possible to position the pump incorrectly. 3.
5.2.5 Fitting the wheel set (accessory) 1. Slacken the two bottom securing screws on the metal guard. 2. Secure the base plate with the two screws. 3. Secure the wheels and washers with the screws on both sides of the base plate. 6 Operation 6.1 Starting the engine DANGER Risk of asphyxiation. Carbon monoxide, unburned hydrocarbons and benzene in the exhaust gas may cause asphyxiation. ▶ Don’t work in closed rooms, trenches or pits and make sure the area is well ventilated.
▶ ▶ ▶ ▶ ▶ ▶ Press and hold down the throttle safety grip. Press and hold down the throttle trigger. Move the start/stop switch to the “start” position. Release the throttle safety grip and throttle trigger. ◁ The half-throttle position is activated. Squeeze the primer bulb 2 to 3 times until the primer bulb is completely filled with fuel. If the following conditions are met, also take this action: Conditions: The engine is cold. Pull the choke lever up. ◁ The choke is activated.

Move the start/stop switch to the “start” position. Release the throttle safety grip and throttle trigger. ◁ The half-throttle position is activated. Squeeze the primer bulb 2 to 3 times to fill the primer pump bulb with fuel only when starting with the engine cold. Check that the cutting disc is free to rotate.
6.4 Cutting techniques WARNING! In order to work optimally with this tool, the following safety instructions must be observed: ▶ Always hold the tool with both hands on the grips provided. Keep the grips dry, clean and free from oil and grease. ▶ Before beginning the work, or if the disc has inadvertently come into contact with an obstacle (e.g. a concealed object), check the cutting disc and guard immediately for possible damage.
• Pulling may occur when making horizontal cuts (e.g. in a floor). The saw may suddenly pull forwards, possibly pulling it out of the operator’s hands. Climbing may occur when making vertical cuts (e.g. in a wall). The saw may suddenly pull upwards, possibly pulling it out of the operator’s hands. Kickback may occur if the prohibited area of the disc is brought into contact with the workpiece.
7.2 Cleaning or replacing the air filter ATTENTION Risk of damage. Entry of dust causes irreparable damage to the product. ▶ Never operate the machine if the air filter is damaged or missing. ▶ When changing the air filter, the product should stand upright and should not be laid on its side. Take care to ensure that no dust finds its way onto the underlying filter screen. Change the air filter if engine performance drops noticeably or if the engine becomes difficult to start. 1. 2. 3. 4. 5. 7.
5. From below, pass the end of the cord through the hole in the starter housing and from below through the pull handle, and securely knot the end of the cord. 6. Pull a length of the starter cord out of the housing as shown in the illustration and pass it through the slot in the spool. 7. Hold the cord securely close to the slot in the spool and turn the spool clockwise as far as it will go. 8. Back the spool off at least ½ to max.
1. 2. 3. 4. Use a gentle twisting motion to pull the cable connector off the spark plug. Use the spark plug wrench to unscrew and remove the spark plug from the cylinder. If necessary, clean the spark plug electrode with a soft wire brush. Check the spark plug gap with the aid of a feeler gauge and, if necessary, reset it to the correct gap (0.5 mm). 5. Fit the ignition cable connector to the spark plug and hold the threaded section of the spark plug against the cylinder. 6.
Use a suitable flat screwdriver (tip width 4 mm/ ⁵/₃₂ ") and do not force the adjusting screw beyond its intended adjustment range. Adjust the idling speed jet (T) so that the engine runs smoothly when idling but the cutting disc does not begin to rotate. ▶ ▶ 7.7 Cleaning the water nozzles 1. Remove the cleaning screw on the curved water distributor. 2. Use a wire to clean the water nozzles. 3. Fit the cleaning screw. 7.

Trouble or fault The diamond cutting disc swings up and may jam. The saw doesn’t start or is difficult to start. Possible cause Action to be taken ▶ Use Hilti cutting discs. Flange for diamond cutting disc does not fit correctly ▶ The fuel tank is empty (no fuel in the carburetor). With cutting discs made by competitors, use the flange for abrasive cutting discs. ▶ Fill the fuel tank. → page 12 ▶ Change the air filter.
Trouble or fault Low engine power / poor cutting performance Possible cause Wrong fuel mixture. Action to be taken ▶ ▶ The disc specification is unsuitable for the material to be cut. Drive belt or cutting disc slips. ▶ ▶ ▶ Cutting disc rotates while the engine is idling. Cutting disc doesn’t rotate. Starter assembly doesn’t work. DSH 600-X Saw blade rotates for longer than 15 seconds after the throttle safety grip is released. 10 Empty the fuel tank and flush out the tank and fuel supply line.
