CHECK AND ADD THE ENGINE OIL
The Briggs & Stratton 675EXi engine on this lawn mower is made with a special feature Check & Add(TM).
The oil never needs to be changed. Before each use check the oil level and add additional oil if the level is
not within the Min - Max levels.
REPLACING THE TRIMMER LINE
When the trimmer line becomes worn to half the original length, replace the trimmer line. For the best
performance, use a heavy gauge 0.155 in. [4 mm] trimmer line.
1. Stop the engine. Wait for all moving parts to stop. Disconnect the wire from the spark plug.
2. Remove the worn trimmer line from line retainer.
3. Cut the length of the trimmer line to 21.5 in. [546 mm]. Use the length guide; located on the shield to
make sure the trimmer line is the correct length. (See Fig. 12)Do not allow the length of the lines to vary
more than one inch. Make sure the trimmer head is balanced and does not vibrate.
4. Thread the ends of the new trimmer line through the out side loops. (See Fig. 13)
5. Take the ends of the line, cross over the line retainer, and thread the ends through the center hole. (See
Fig. 14)
