TIPS FOR BEST TRIMMING RESULTS
• Keep the trimmer attachment parallel to the ground.
• Trim only when grass and weeds are dry.
The cutting head and shield are designed to allow the unit to cut in either
direction, from right to left or left to right.
The life of the trimmer line is dependent upon:
Following the trimming tips _31_
- What vegetation is being cut
- Where vegetation is being cut
DECORATIVE TRIMMING
Decorative trimming is accomplished by
removing all vegetation around trees, posts,
fences and more. Rotate the whole unit so
that the trimmer attachment is at a 30 ° angle _ L _
to the ground (Fig. 14). Fig. 14

CHECKING THE OIL LEVEL
m i
I _k WARNING:
To avoid serious personal injury, always turn the
un t off and a ow it to cool before cleaning or maintaining it.
The importance of checking and
maintaining the proper oil level in
the crankcase cannot be
overemphasized. Check oil before
each use:
1. Stop the engine and allow oil
to drain into the crankcase.
2. Place the engine on a flat,
level surface with the cutting
head shield hanging off a work
bench or table to get a proper
oil level reading (Fig. 18).
3. Keep dirt, grass clippings
and other debris out of the
engine. Clean the area
around the oil fill plug before
removing it.
4. Remove the oil fill plug.
5. Look into the oil fill hole; use
a flashlight if needed. The oil
should be just touching the
inner most thread (Fig. 19).
6. If the oil level is not touching
the inner most thread on the
oil fill hole, add a small
amount of oil to the oil fill hole
and recheck (Fig. 19). Repeat
this procedure until the oil
level reaches the innermost
thread on the oil fill hole.
NOTE: Do not overfill the unit.
NOTE: Make sure the O-ring is
in place on the oil fill plug
when checking and
changing the oil (Fig. 20).

2. Pour the oil out of the oil fill
hole and into a container by
tipping the unit to a vertical
position (Fig. 21). Allow ample
time for complete drainage.
