plug.

whichever comes first. Oil should be changed 
when engine is warm.

2. Clean area around oil cap.
3. Tip the string trimmer on its right side.

4. Place a container for the oil under the oil 

cap.

5. Remove oil cap and let the oil drain. Tip 

the unit more to drain all the oil from the 
engine if necessary.

6. Place the unit upright.
7. Refill the engine with oil recommended in 

the Engine Manual.

cooling fins every 25 hours to prevent damage 
caused by overheating.

REPLACING TRIMMER LINE

(Figure 5)

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.

CAUTION: 

Before tipping unit, 

remove enough fuel so no 
spillage will occur. A piece of 
plastic bag may be used to seal 
fuel tank when tipping unit. To 
seal, remove fuel tank cap, 
cover fuel tank opening with 
plastic, replace and tighten cap 
securely before attempting to tip 
unit. Be sure to remove plastic 
before operating unit.
