CARE, MAINTAINANCE, STORAGE AND TRANSPORT
Spark plug: Check every 12 hours or if starting problems are experienced. When the engine is cold,
remove the plug cap and unscrew the spark plug with a suitable spark plug socket (Fig.11). If the
electrodes are excessively soiled or worn then replace with an equivalent new spark plug (e.g. NHSP
LD L8RTF).
Excessive soiling may be due to a) too high ratio/poor quality 2-stroke oil or b) clogged air filter.
Replace spark plug and screw in by hand to avoid stripping of thread, then tighten with socket.
Air filter: Clean air filter regularly. Unscrew cover (Fig.12) and remove foam filter (Fig.13). Wash
filter with soap and water and allow drying before replacing. Fit new filter if damaged.
Fuel intake filter: Replace every 12 months. Remove with hook through tank refilling inlet.
Transport and storage: If brushcutter is unused for more than 2 months or being transported, then
empty the fuel tank. Before storage allow the engine to cool. Store the unit indoors in a dry, ventilated
and locked place, out of reach of children.
CAUTION
Allow engine to reach maximum RPM before cutting brush or trimming grass.
For the most effective cutting, cut approximately 25 mm into the brush / grass, allowing the tip of the
line (teeth on the bade disc) to cut. Do not force the brushcutter / trimmer into the work.
Periodically remove weed wrap from beneath the cutting-head / blade to prevent overheating the
engine. Weed wrap occurs when strands of weeds become entangled around the shaft beneath the
cutting-head / blade. Remove weed wrap, with a screwdriver or similar device and ensure cutting-head
/ blade 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.15). Take out the spool ( Fig.16).
Remove any old bits of line. The new nylon line should not exceed 6,0 metres in length. (Use only
genuine Lawn Star 2.40 mm replacement line). Uncoil the new line completely. Double over in the
middle so that you have two equal lengths. Insert the doubled-over loop into the slot provided in the
spool divider and push to the bottom (Fig.17). 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, the centre divider rim should still be visible. 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.18). Pass the line ends through the eyelets in the
spool housing and replace spool into housing (Fig.19). Make sure the spring is still in place inside the
spool housing. Replace the cap ensuring that it is firmly clipped in place ( Fig.20 ). 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 starting engine.
ENSURE CAP IS
PROPERLY LOCKED IN PLACE BEFORE STARTING ENGINE.
FITTING AND CHANGING THE CUTTING HEADS.
Ensure unit is switched off and remove spark plug cap before carrying out changes.
Your brush cutter /trimmer are supplied with both a tap-to-feed cutting head and a blade disc. To
attach the tap-to-feed cutting head remove the nut if fitted by turning it in a clock-wise direction with
the spanner provided. Ensure both spacer and dust cover (Fig.22a-No1 and No3) are fitted. Attach tap-
to-feed cutting head by rotating it in an anti-clock-wise direction (Fig.22a-No2).
To attach the cutting disc assemble as per Fig.21ensuring spacers are in the correct positions,
tightening the nut in an anti-clock-wise direction (Fig.22 -No2).
To attach the fixed-line cutting head (LSB 5243 only) assemble as per figure 22b and tightening the
nut anti-clock-wise (Fig.22b-No2).
To remove the blade disc, fixed line and tap-to-feed cutting head insert the 4mm allen key provided
into the hole (Fig 21a-No1) and rotate until it locks in place. Use the socket to unscrew nut or by hand
rotate the tap-to feed cutting head in the clock-wise direction.
Remove the skirt from the safety guard when the tri-blade, cutting disc and fixed line cutting head are
fitted (Fig.23a). This is done by removing the screw (Fig.23a-No1) at the back of the guard and
unclipping the skirt. This skirt must be re-fitted when the tap-to-feed cutting head is used to ensure that
nylon cutting line length is maintained by the blade fitted to this skirt (Fig.23b).
