If you need to cut hard objects such as concrete walls or reinforced concrete walls outdoors or on construction sites, TCBL's gas concrete saw will be a better choice for you!!
DL400 Gas concrete saw
Specification:
Displacement: 92cc
Power:5.0kw(6.7hp)
Constant rpm: 2200rpm
Blade Diameter: 400mm(16inch)
Max cutting depth: 29cm
N.W: 14kg
Gasoline: Mixing gasoline and two-stroke engine oil
Unique function of our ring saw:
1. The built-in automatic filter compensation function can maintain high power and reduce fuel consumption.
2. The dust-proof sealed starter device seals the reset spring and pulley bearing, making the starter almost maintenance free and more reliable.
3. The engine can output convenient torque, expand the speed range, and therefore has the highest cutting ability. The fuel consumption has decreased by up to 20%, and the emissions have decreased by 60%.
4. In terms of design, the engine and starter ensure quick and easy start-up of the machine. The tensile strength of the starter rope decreases by up to 40%. (Reduced the pressure during startup.)
5.When you press the fuel injection pump button, the fuel pump will be pumped to the carburetor. Only a few pulls are needed to start, which means the machine is easier to start
6. The cutting depth is 290 mm (11.4"), which is twice the cutting depth of traditional saw blades. It can effectively cut from one side.
7. The efficient shock absorber reduces the load on the arms and hands.
8. This cutting equipment is equipped with a water cooling and dust prevention system, which can perform wet cutting and suppress dust generation.
Types of gasoline used:
Our concrete saw gas powered is two-stroke machine and it needs to use two-stroke oil, below is the Precautions for gasoline use:
• Do not use the two-stroke oil for water-cooled engines, the so-called outboard oil (TCW grade).
• Never use oil for a four-stroke engine.
MIX:

• Mix gasoline and oil in a clean fuel container
• Be sure add half of gasoline first. Then add all the oil. Mix (shake well) the mixture. Finally add the other half of the gasoline.
• Be sure to thoroughly mix (shake well) the fuel mixture before adding it to the fuel tank of the machine.
• Do not mix more than a month's worth of oil at once.
How to start our Gasoline cutter?
Press the throttle switch safety button and simultaneously press the linkage push rod . Set the linkage lever to: cold start H, hot start I (even if the engine is running continuously, it is still in a cold state).
If the engine does not start:
If the linkage lever is not quickly moved to"hot start"(I) after the engine ignition starts, the combustion chamber may have flooded.
1: Open the carburetor cover twist lock and remove the carburetor cover.
2: Vertically remove the air baffle.
3: Remove the spark plug plug.
4. Set the linkage lever to the"stop"position.
5: Unscrew the spark plug and let it dry.
6: Pull the starting rope several times to ventilate the combustion chamber thoroughly.
7: Reinstall the spark plug.
8: Set the linkage lever to the hot start position , even if the engine temperature is low. Press the pressure reducing valve button to open the pressure reducing valve, please start the engine now.
