SYMBOL EXPLANATION

Thank you for purchasing the Lawn Star trimmer which is one of the finest and most advanced
trimmers today’s technology can produce. Before you begin using it, please read this manual carefully
and familiarise yourself with the control and the proper use of this product to ensure you get the best
possible performance from it.

SAFETY PRECAUTIONS

Inspect your trimmer and its supply/extension cable before each operation. If any part is damaged or
worn, repair or replace before operation . Do not operate with damaged or tangled supply/extension
cable. Keep cable away from cutting head.
Use only genuine Lawn Star (Pty)Ltd. replacement parts when servicing or repairing the unit. These
parts are available from your supplying dealer or service agent. Use only genuine Lawn Star
replacement nylon cutting line , never metal.
WARNING : To prevent electrical shock hazards , use only extension cables suitable for outdoor use,
with splash-proof socket outlets, preferably protected by sensitive Residual Current Device (RCD)
with tripping current 0f not more than 30 mA.
Disconnect the unit from the power supply when unattended or not in use, before servicing or when
changing accessories, such as the spool.

It is essential that the operator wears safety goggles , protective clothing and sturdy , non-slip
footwear.

Do not use your trimmer for any jobs other than those for which it was intended. Do not use for edge
trimming unless adequately guarded. Do not force your trimmer. If motor labours, pull away from
grass.
Do not operate trimmer without a line-trimming blade as over-extended line is dangerous and will
damage motor and invalidate warranty.
Use care in picking up or holding the unit. Do not grasp the line-trimming blade located at the edge of
the underneath side of safety guard.
Avoid unintentional starting. Do not carry a plugged-in unit with your fingers on the switch. Inspect
the area to be cut and remove all debris that could be entangled in the cutting head. Also remove any
object that the unit may sling during cutting.
Avoid dangerous environments. Do not use the unit in poor light or in damp or wet locations. Do not
use in the rain. Do not use on steep slopes , especially if damp. Work across slope faces , not up and
down. Do not over-reach. Ensure good footing and balance are maintained.
Keep hands and feet clear of the rotating head while unit is in use. Cutting elements continue to rotate
for a few seconds after switch-off.
Do not allow children under 16 , nor anyone who is not familiar with these instructions to use the
trimmer. Children , pets and onlookers should be kept at least 15 meters away from the work area ,
unless shielded by an effective solid barrier.
When not in use, store the unit indoors in a dry and locked place , out of reach of children.

PREPARATIONS FOR USE

For models with edging wheel, remove the wheel and bracket from the bag and attach to the guard by
inserting and tightening the two screws supplied.(Fig.1 )
Mount the guard from below by passing over the cutting head until the guard bayonet projections
locate into the housing flange recesses ( Ensure that the cutting lines are not trapped ). Turn the guard
until it locks into place at the end of its travel ( Fig.2). Insert locking screw supplied and tighten ( Fig.
2- No 3 )
Attach “D” assist-handle to the upper half of tube by clipping over the shaft (Fig.3-No 1). Adjust to the
most comfortable position for trimming, then fit and tighten the bolt and knob provided (Fig.3-No 2).
Rotate the “D” assist-handle through an angle of 180 degrees when edging with your trimmer.
Connect the plug provided with the trimmer , to a suitable female socket. Attach to an extension cord
not more than 40 meters of length. Use 2-core insulated cable , minimum (HO5VV-F ) 2x1,0mm , in
turn connected to a suitable mains connection plug. All components should meet your national , IEC or
EN specifications.

THE USE OF THIS TRIMMER FOR COMMERCIAL OR RENTAL PURPOSES WILL
INVALIDATE THE WARRANTY.

CARE AND MAINTAINANCE
Do not oil – this is unnecessary.
Keep air intake vents, in plastic housing above motor , free of grass cuttings and dirt to ensure
unobstructed cooling air-flow through the motor. Clogged-up air intake vents cause the motor to
overheat and can result in failure.

OPERATING INSTRUCTIONS

Attach extension cord with suitable female coupler to the plug provided on the trimmer. Secure cord
and extension cord as shown in ( Fig.4 ) to prevent accidental detachment of plug.

TRIMMING PROCEDURES
When properly assembled with safety guard and cutting-head, your unit will trim unsightly weeds and
tall grass in those hard-to-reach areas along fences, walls, foundations and around trees.
NOTE : Even with care, trimming around foundations, brick or stone walls, kerbs etc. will result in
above normal line wear.

TRIMMING
For normal trimming, the trimmer should be inclined at about 30 degrees to the lawn, while cutting
towards the left in a sweeping motion. Always cut away from the operator. Do not pull trimmer in
toward operator.

FENCE / FOUNDATION TRIMMING
Approach trimming around chain link fences, picket fences, rock walls and foundations slowly to cut
close without whipping line against the barrier. If the line comes into contact with rock, brick walls, or
foundations, it may fray as it wears. If line snags fencing , it may snap off.

TRIMMING AROUND TREES
Trim around tree trunks with a slow approach so line does not contact bark. Walk around the tree
trimming from the right to the left. Approach grass or weeds with the tip of the line and tilt cutting­head forward.

EDGING
For edging, flip the trimmer over and turn the “D” assist-handle through 180 degrees. To conserve
line, avoid excessive cutting against stone / cement surfaces .

CUTTING-HEAD LINE FEED
As the cutting line wears and shortens the cutting performance is reduced. In order to maintain
optimum performance ensure that the cutting lines are fully extended. To extend additional line, tap
the centre of the rotating head lightly on the lawn WHILE THE UNIT IS RUNNING. The line will
automatically lengthen by approximately 25mm. Excess line will be clipped off by the blade on the
safety guard.

CAUTION

Avoid excessive intermittent switch operation during trimming as this will reduce motor life.
Allow motor to reach maximum RPM before trimming grass.
For the most effective trimming , cut approximately 25mm into the grass , allowing the tip of the line
to cut. Do not force the trimmer into the work.
Periodically remove weed wrap from beneath the cutting-head to prevent overheating the motor. Weed
wrap occurs when strands of weeds become entangled around the shaft beneath the cutting-head
(Fig.11). Remove weed wrap, after disconnecting unit from power supply, with a screwdriver or
similar device and ensure cutting-head rotates freely.

RENEWING THE CUTTING LINE

Hold the cutting-head with one hand and unclip the cap with the other hand by pressing in the tabs on
either side of the cutting head and simultaneously lifting the cap ( Fig.5 ).Take out the spool ( Fig.6 ).
Remove any old bits of line. The new nylon line should not exceed 8,0 meters in length and must
conform to the specification listed below ( Use only genuine Lawn Star replacement line). Uncoil the
new line completely. For dual-line cutting heads, double over in the middle so that you have two equal
lengths. Insert the doubled-over loop into one of the two slots provided in the spool divider and push to
the bottom. The slots provided suit either 1.6mm diameter or 2.0mm diameter line (Fig.7 ). Wind the
two lengths onto the spool (one length on each side of the spool divider ) in the direction shown on the
spool flange. When each of the spool compartments is full, about 2mm of the centre divider rim should
still be visible. For single-line cutting heads wind max 4,0m of line in one compartment only. Ensure
the line is wound neatly and tightly. This is important. Clip the ends of the line into the holding slots
provided , leaving enough free length to facilitate threading through the eyelets ( Fig.8 ).Pass the line
ends through the eyelets in the spool housing and replace spool in housing ( Fig.9 ). Make sure the
spring is still in place inside the housing shaft . Replace cap ensuring that it is firmly clipped in place

(Fig.10 ). Pull on the line ends to release the spool from the “ locked “ position to the operating

position. Trim off excess trimming line that extends beyond the line trimming blade before switching
on. ENSURE CAP IS PROPERLY LOCKED IN PLACE BEFORE USING.
