OPERATING INSTRUCTIONS
Fig. 15a
ADJUSTING THE TRIMMING LINE LENGTH
Your trimmer is equipped with a bump head,
which allows the operator to release more
trimming line without stopping the motor. As the
line becomes frayed or worn, additional line can
be released by lightly tapping the trimming head
on the ground (Fig. 15a - Models 105r and 132r;
Fig. 15b - Model 137r) while operating the
trimmer at high speed.
NOTE: Always keep the trimming line fully
extended. Line release becomes more
difficult as cutting line becomes shorter.
Fig. 15b
Each time the head is bumped, approximately
1 in (25.4 mm) of trimming line is released. A
blade in the string guard will cut the line if
excess line is released.
For best results, tap the head on bare ground or
hard soil. If line release is attempted in tall grass,
the motor may overheat. Always keep the
trimming line fully extended. Line release
becomes more difficult as the cutting line
becomes shorter.

WARNING: Do not remove or alter
the lead cutting blade assembly.
Excessive line length will cause the
motor to overheat and may result in
serious personal injury.
DECORATIVE TRIMMING
Decorative trimming is accomplished by
removing all vegetation around trees, posts,
fences, etc. Use a 30-degree angle when
trimming with this method (Fig. 16a - Models
105r and 132r; Fig. 16b - Model 137r).
EDGING - MODELS 132r AND 137r
For edging with the trimming head attachment
on Models 132r and 137r, locate and lock the
release button into the second hole (90 degrees)
or third hole (180 degrees) in the Click-Link
system (Fig. 14).
