Service And Adjustments - Ariens ST622 Owner's/Operator's Manual

WARNING: AVOID INJURY. Read
and understand the entire Safety
section before proceeding.
REPLACING TRIMMER LINE
Replace the trimmer line when it extends less
than 4 inches (10.2 cm) from cutter disk. For
best results, use only genuine Ariens
replacement trimmer line.
1. Stop the engine and wait for all moving
parts to stop. Disconnect the spark plug
wire and place it securely away from the
spark plug.
2. Remove the worn trimmer line from the
cutter disk.
3. Thread the two ends of the trimmer line
up from the bottom, through the two holes
in the cutter disk.
4. Cross the line and thread the ends of the
line through the two holes on the side of
the cutter disk.
5. Make sure the ends of the line extend
through the cutter disk at the same length.
Uneven trimmer lines cause the trimmer
head to be out of balance, which results in
excessive vibration.
6. Pull trimmer line tight.
7. If necessary, cut the ends of the trimmer
line to the same length.

spacers must be in place above the cutter
disk.

spacer between the cutter disk and the height
