Mixing fuel

This machine uses a mixture of 1:50 of engine oil to petrol. We highly recommend STIHL HP ULTRA TWO STROKE ENGINE OIL as it is made specifically for STIHL engines.

Looking after your Line Trimmer

Cleaning your Line Trimmer from debris and grass clippings with a damp cloth or soft brush and having it serviced regularly at your local STIHL SHOP is a great way to take care of your machine.

Doubling your warranty

This Line Trimmer's 2-year domestic warranty can be doubled by joining our Service Advantage program. Simply purchase STIHL HP ULTRA TWO STROKE ENGINE OIL with the FS 38 and we will sign you up.

Ongoing service and parts

Your local STIHL SHOP can provide you with technical support and assistance for the life of your machine. In addition STIHL continues to make spare parts for 10 years after they have retired a product from production - so buying a STIHL is always a great long term investment.

Using nylon line

Always use the correct diameter of nylon line for your Line Trimmer (2 mm for this model). Be careful not to use excess nylon as the added length will reduce rotation speed and power.

Storing your Line Trimmer

Store your Line Trimmer on a flat service in a secure location that is out of the reach of children. If you are not using your machine regularly, do not leave fuel sitting in the tank.
