WARNING:
Always wear hearing
protection and eye protection. Never lean
over the trimmer head. Rocks or debris can
ricochet or be thrown into eyes and face and
cause blindness or other serious injury.
Maintain firm footing and hold trimmer with
both hands with right hand on the rear handle/
throttle control and the left hand on the front
handle. Always keep engine and trimmer
head below waist level.
Do not run the engine at a higher speed than
necessary. The cutting line will cut efficiently
when the engine is run at less than full throttle.
At lower speeds, there is less engine noise and
vibration. The cutting line will last longer and will
be less likely to “weld” onto the spool.
Always release the throttle trigger and allow the
engine to return to idle speed when not cutting.
To stop engine:
S
Release the throttle trigger.
S
Push and hold the STOP switch in the
STOP position until the engine stops.
TRIMMER LINE ADVANCE
(Models W25CB, W25SB, W25CBK,
W25SBK)
The trimmer line will advance approximately 2
inches (5 cm) each time the bottom of the
trimmer head is tapped on the ground with the
engine running at full throttle.
The most efficient line length is the maximum
length allowed by the line limiter.
Always keep the shield in place when the tool
is being operated.
To advance line:
S
Operate the engine at full throttle.
S
Hold the trimmer head parallel to and above
the grassy area.
S
Tap the bottom of the trimmer head lightly
on the ground one time. Approximately 2
inches (5 cm) of line will be advanced with
each tap.
Always tap the trimmer head on a grassy
area. Tapping on surfaces such as concrete
or asphalt can cause excessive wear to the
trimmer head.
If the line is worn down to 2 inches (5 cm) or
less, more than one tap will be required to ob-
tain the most efficient line length.
WARNING:
For models W25CB,
W25SB, W25CBK, W25SBK, use only 0.080
inch (2 mm) diameter line. Other sizes of line will
not advance properly and will result in improper
cutting head function or can cause serious
injury. For models W25CF, W25SF, W25CFK,
W25SFK, use only 0.095 inch (2.4 mm) diame-
ter cut length line. Do not use other materials
such as wire, string, rope, etc. Wire can break
off during cutting and become a dangerous pro-
jectile that can cause serious injury.
CUTTING METHODS
WARNING:
Use minimum speed
and do not crowd the line when cutting around
hard objects (rock, gravel, fence posts, etc.),
which can damage the trimmer head, become
entangled in the line, or be thrown causing a
serious hazard.
S
The tip of the line does the cutting. You will
achieve the best performance and mini-
mum line wear by not crowding the line into
the cutting area. The right and wrong ways
are shown below.
