OPERATING INSTRUCTIONS
Trimming Procedures
PracticalTips
o Practice all operating techniques with the engine switched off before you start to use the machine
. Remove Weed/Grass wrapped around Head/Shaft.
D0 NoT use steel wire or ptastic-coated steel wire of any kind with your string head. Serious
opentor injury can result.
Periodically remove weed wrap to prevent overheating the drive shaft. Weed wrap occurs
when strands of weed become entangted around the shaft beneath the debris shield. This
condition prevents the shaft from being property cooled.
' when D13pe'! equlppeo vrith a guard and cutting head, your unit willtrim unsighfly weeds and tall grass in those
hard-tc-reacn areas - along fences, walls, foundations and around trees. lt can also be used for scalping to
remove vegetation down to the ground for easier preparation of a garden or to clean out a parlicul ar area.(Fig. 23)
A properly equipped guard must be located on the unit at alttimes.
Trimming / Mowing
' When properly equipped with a guard and cutting head, your unit will trim unsighly weeds
and tall grass in those hard-to-reach areas - along fences, walls, foundations and around
trees. lt can also be used for scalping to remove vegetation down to the ground for easier
preparation of a garden or to clean out a particulat area. Fig.23
Fence / Foundation Trimming
' Approach trimming around chain link fences, picket fences, rock walls and foundations slowly to cut close without
whipping string against the barrier. lf the string comes in contact with rock, brick walls, or foundations, it will break
or fray. lf string snags fencing, it will snap off.
Trimming Around Trees
' Trim around tree trunks with a slow approach so string does not contact bark. Walk
around the tree trimming from left to right. Approach grass or weeds with the tip of the
string and tilt cutting head slighfly fonruard.
Scalping (Fig, 24)
o scalping refers to removal of all vegetation down to the ground. To do this, tilt the cutting
head to about 30 degree angle to the left. By adjusting the handle you will have better
control during this operation. Do not attempt this procedure if there is any chance flying
debris could injure operator, other people or cause damage to property.
Use ertreme caution when SCALPING. Keep a distance of lS Metres between operat,t; other
people and animals during these operations.

Maintenance - Oil (0il Grade SAE 10W30)
Maintenance of 0il
Check oil level before every use.
Replace oil after the first 4 hours of operation.
Refill oil when level reaches lower indicator on oil gauge.
Do not fill beyond upper indicator on oil gauge. (0il
capacity 80mL)
Replace oil after every 10 hours of operation.
Replace oil if it is dirty or contaminated.
Fig. 25
Maintenance - Air Filter
Maintenance of the Air Filter
Always switch off the machine and pull off of spark plug H.T.
lead before carrying out any maintenance work.
N0TE: DirU air filters reduce the engine output by supply too
little air to the carburettor.
Regular checks of the air filter is essential. The air filter should be
checked every 1 0 hours of operation and cleaned if necessary. The air
filter should be checked more frequently when used in dry and dusty
environments.
Remove the air filter cover by squeezing the retaining clips at the
top of the air filter cover (Fig. 25)
2. Remove the filter element (Fig. 26)
3. Clean the filter element by washing in soapy water and allowing it
to dry completely.
4. Soak in oil and squeeze off excess.
5. Assemble in reverse order.
Never clean the air filter with petrol or inflammable solvents.
Make sure Air Filter is fitted correctly, (warranty will be void if engine is damaged due to
incorrect fitment).

Storage
A lf you .fail to follow these instructions correctly before storing the
/\ machine, deposits may flrm on the interior of the carburettor
/ ' \ & may result in the engine being more difficult to start or the
machine sufferi n g permanent damage,
Storage Preparation
1. Carry out all the maintenarce work require prior to storing.
2, Drarn the fuei out of :re tank.
3. When the fuel has been drained, staft the engine.
4' Allow the engine to run at idling speed until it stops. This will clean the remainder of the fuet out of the carburettor.
5. Leave the machine to cool (approx. S minutes).
6. Clean the exterior housing of the machine.
7 ' Store the machine jn a cold, dry place where it is out of the reach of ignition sources & inflammable substances.
8' Always store engine ripright or with trimmer shaft hanging in the downward position. Do not store upside down or
on the engines sides Fertilizers and other chemical garoen prooucts often contain substances that accelerate the rate of
corrosion of metals. Do not store the machine on or near ferlilizers or other chemicals.
Before Restarting
Recheck engine oil is sufficient.
Transport
To transpotl the machine. first empty the petrol tank. Pump the primer to completely remove fuel from the carburettor
& empty excess from the tank clean coarse dirt off the machine with a brush. Traniport Trimmer with engine in upright
position. Do not transport with engine upside down or on its side.
