Stihl TS 400 Cutquik Instruction Manual

The correct fuel mix ratio for the Stihl TS 400 Cutquik is 50:1, which means 50 parts gasoline to 1 part 2-stroke engine oil. Use high-quality 2-stroke oil to ensure optimal performance and longevity.
First, check the fuel level and ensure the fuel is fresh. Inspect the spark plug for wear and replace if necessary. Clean or replace the air filter if it's dirty. Also, check the decompression valve for proper operation.
Regular maintenance includes checking and cleaning the air filter, inspecting and replacing the spark plug as needed, checking and adjusting the drive belt tension, and cleaning the cooling fins. Additionally, ensure the water supply is functioning properly.
To replace the cutting wheel, first ensure the machine is turned off and the spark plug is disconnected for safety. Use the included wrench to remove the central bolt securing the wheel. Remove the old wheel and replace it with the new one, ensuring it's properly seated before tightening the bolt.
Overheating can be caused by a dirty air filter, clogged cooling fins, or insufficient water supply for dust suppression. Check these components and clean or replace them as needed. Ensure the water supply is functioning to keep dust down and the saw cool.
For cutting concrete, use a diamond abrasive wheel specifically designed for masonry. Ensure the wheel is rated for the RPM of the TS 400 and is appropriate for the type of concrete being cut.
To adjust the drive belt tension, locate the tensioning nut and turn it clockwise to increase tension or counterclockwise to decrease it. Proper tension is achieved when the belt deflects about 3-5 mm with moderate pressure. Ensure the machine is off and the spark plug is disconnected before making adjustments.
Yes, the Stihl TS 400 can be used for wet cutting. Connect a water supply to the attachment point on the saw to provide a continuous flow of water. This helps suppress dust and keep the cutting wheel cool. Ensure the water flow is adequate before starting the cut.
Loss of power can result from a clogged air filter, a dirty fuel filter, or a worn spark plug. Clean or replace these components as necessary. Also, check the exhaust for blockages and ensure the fuel mix is correct and fresh.
The spark plug should be inspected regularly and replaced every 100 operating hours or sooner if it shows signs of wear or damage. Use only the recommended spark plug type to ensure proper operation.
