Vibration Hazard
This appliance vibrates during use.
Repeated or long-term exposure to vibration may
cause temporary or permanent physical injury,
particularly to the hands, arms and shoulders.
To reduce the risk of vibration-related injury:
.
1 . Anyone using vibrating appliances regularly or for
an extended period should first be examined by
a doctor and then have regular medical checkups

past hand injuries, nervous system disorders,
diabetes, or Raynaud’s Disease should not use this
appliance. If you feel any symptoms related to
vibration (such as tingling, numbness, and white
or blue fingers), seek medical advice as soon as
possible.
2. Do not smoke during use.. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury..
3. Wear suitable gloves to reduce the
vibration effects on the user.
4. Use appliances with the lowest vibration when
there is a choice between different processes.
5. Include vibration-free periods each day of work.
6. Grip appliance as lightly as possible
(while still keeping safe control of it).
Let the appliance do the work.
7. To reduce vibration, maintain the appliance
as explained in this manual. If any abnormal
vibration occurs, stop use immediately.

Trimming
Figure11

Page 13
WWW.LITHELI.COM
Item U1GT21112
Operating Tips
•Keep the trimmer tilted toward the area being
cut; this is the best cutting area.
•The string trimmer cuts when you move it from
left to right. This prevents the trimmer from
throwing debris at you.
•Use the tip of the string to do the cutting; do not
force the string head into uncut grass.
•Wire and picket fences can cause the string to
wear rapidly and even break. Stone and brick
walls, curbs, and wood can also cause the string
to wear rapidly.
•Avoid trees and shrubs. The string can easily
damage tree bark, wood moldings, siding, and
fence posts.

Replacing the Spool
Use only 2 mm (0.08 inch) diameter monofilament
string.
Important: Using a larger diameter string
causes the motor to overheat and fail.
1. Remove the battery.
2. Push in the tab on the side of the spool retainer
(Figure 13).

3. Pull the spool retainer up to remove it and
remove the spool.
4. To install the new spool, make sure that the
string is captured in 1 of the retaining slots on
the new spool. Make sure the end of the string
extends approximately 150 mm (6 inches).
5. Install the new spool so that the string aligns
with the eyelet in the string head. Thread the
string into the eyelet.
6. Pull the string extending from the string head
so that the string releases from the slot in the
spool.
7. Install the spool retainer by pressing the tabs
into the slots and pushing down until the spool
retainer clicks into place.

Figure14
Spool
Anchor Slot
Note: Remove any old string remaining on the
spool.
3. Each side of the spool accepts approximately
2.5 m (8 ft) of string. Use only 2 mm (0.08
inch) diameter monofilament string.
Note: Do not use any other gauge or type of
string, as this could damage the trimmer.
4. Insert the string into the anchor slot in the
upper part of the spool (Figure 14). Wind the
string onto the spool in the direction shown
by the arrows on the spool.
5. Place the string in the slot on the upper spool
flange, leaving about 150 mm (6 inches)
extended beyond the slot.
Note: Do not overfill. After winding the string,
there should be at least 6 mm (1/4 inch)
between the wound string and the outside
edge of the spool.
6. Replace the spool and the spool retainer; refer
to Replacing the Spool (page 13).
Replacing the Blade
1. Press the lock shaft button and turn the spool
counterclockwise until it is removed.
2. Take out the brush breaker blade from the
accessory package and remove the brush
breaker sheath.
3. Insert the blade into the brushless motor
assembly, cover the blade pressing plate and
cover the blade pressing cover.
