SAFETY ALERT SYMBOL: Indicates
danger, warning, or caution. Attention is
required in order to avoid serious personal
injury. May be used in conjunction with
other symbols or pictographs.
NOTE: Advises you of information or instructions vital to
the operation or maintenance of the equipment.
DANGER: Failure to obey a safety warning will
result in serious injury to yourself or to others.
Always follow the safety precautions to reduce
the risk of fire, electric shock, and personal injury.
WARNING: Failure to obey a safety warning
can result in injury to yourself and others.

RULES FOR SAFE OPERATION
• CORD SETS: Make sure your cord set is in good
condition. When using a cord set, be sure to use a
cord that is heavy enough to carry the current that your
unit will draw. An undersized cord set will cause a drop
in line voltage resulting in loss of power and
overheating. See the operator’s manual for the unit that
will power this add-on for the recommended cord size.
• Inspect all extension cords and the unit power
connection periodically. Look closely for deterioration,
cuts or cracks in the insulation. Also inspect the
connections for damage. Replace the cords if any
defects or damage appear.
• Prevent disconnection of the straight shaft trimmer
powerhead from extension cord during operation by
using a plug-receptacle retaining strap, connector, or
by making a knot as shown below:
• Avoid dangerous environments. Never operate your unit
in damp or wet conditions. Moisture is a shock hazard.
•
Do not use the unit in the rain. Do not use in or around water.

needed to do the job. Do not run the engine at high
speed when not in use.
• Always stop the engine/motor when operation is
delayed or when walking from one location to another.
.•
If you strike or become entangled with a foreign object, stop
the engine/motor immediately and check for damage. Have
any damage repaired before attempting further operations.
•Stop the unit IMMEDIATELY if you feel excessive
vibration. Vibration is a sign of trouble. Inspect thoroughly
for loose nuts, bolts or damage before continuing. Repair
or replace affected parts as necessary.
• Stop and switch the unit to off for maintenance, repair,
or for changing add-ons or other attachments. The unit
must be stopped and the cutting head no longer
turning to avoid injury.

each use.
• Keep these instructions. Refer to them often and use
them to instruct other users. If you loan someone this
unit, also loan them these instructions.
• Only qualified personnel should perform any repairs
or maintenance procedures that are not described
in this manual.
• Check shear bolts, engine mounting bolts and other
bolts at frequent intervals for proper tightness to be

WARNING: Read and understand operator’s
manual for unit to be used with this add-on
prior to operation.
CAUTION: Lock the release button in the
primary hole and securely tighten the knob
before operating this unit.
WARNING: To avoid serious personal injury
and damage to the unit, shut unit off before
removing or installing add-ons.
CAUTION: The add-ons with the coupler
system are to be used in the primary hole
only unless stated otherwise in the specific
add-ons operator’s manual. Using the wrong
hole could lead to personal injury or damage
to the unit.
OPERATING INSTRUCTIONS
NOTE: Do not rest the Bump Head™ on the ground
while the unit is running.
Some line breakage will occur from:
• Entanglement with foreign matter
• Normal line fatigue
• Attempting to cut thick, stalky weeds
• Forcing the line into objects such as walls or fence posts
TIPS FOR BEST TRIMMING RESULTS
• For best trimming results, operate unit at full throttle.
• Keep the cutting attachment parallel to the ground.
• Do not force the cutting attachment. Allow the tip of
the line to do the cutting, especially along walls.
Cutting with more than the tip will reduce cutting
efficiency and may overload the engine.
• Cut grass over 8 inches (200 mm) by working from top
to bottom in small increments to avoid premature line
wear or engine drag.
• Cut from left to right whenever possible. Cutting to the
right improves the unit's cutting efficiency. Clippings
are thrown away from the operator.
• Slowly move the trimmer into and out of the cutting
area at the desired height. Move either in a forwardbackward or side-to-side motion. Cutting shorter
lengths produces the best results.
• Trim only when grass and weeds are dry.
• The life of your cutting line is dependent upon:
• Following the previous trimming techniques
• What vegetation is being cut
• Where it’s being cut
For example, the line will wear faster when trimming
against a foundation wall as opposed to trimming
around a tree.
DECORATIVE TRIMMING
Decorative trimming is accomplished by removing all
vegetation around trees, posts, fences, etc.
Rotate the whole unit so that the cutting attachment is at
a 30° angle to the ground (Fig. 7).
HOLDING THE TRIMMER
Before operating the unit, stand in the operating position
(Figs. 4 & 5). Check for the following:
•
The operator is wearing eye protection and proper clothing.
• The right arm is slightly bent, and the hand is holding
the shaft grip.
•
The left arm is straight, and the hand is holding the D-handle
or J-handle.
• The unit is at waist level.
• The cutting attachment is parallel to the ground and
easily contacts the vegetation to be cut without the
operator having to bend over.
Fig. 4
Fig. 5
ADJUSTING TRIMMING LINE LENGTH
The Bump Head™ cutting attachment allows you to
release trimming line without stopping the engine. To
release more line, lightly tap the cutting attachment on the
ground (Fig. 6) 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. 6
Fig. 7
8
WARNING: Always wear eye, hearing, foot
and body protection to reduce the risk of
injury when operating this unit.
Each time the head is bumped, about 1 inch (25.4 mm.)
of trimming line is released. A blade in the cutting
attachment shield will cut the line to the proper length if
excess line is released.
For best results, tap the Bump Head™ on bare ground or
hard soil. If line release is attempted in tall grass, the
engine may stall. Always keep the trimming line fully
extended. Line release becomes more difficult as the
cutting line becomes shorter.

6. Pull the line from the outer spool until the line is tight
against the inner reel (Fig. 11).

line, 10 feet (3 m) long.
2. Hold the outer spool and turn the inner reel
counterclockwise to line up the arrows on the outer
spool and inner reel (Fig. 8).
