Page 5
Ver 3 - September 2016
background
1.6.2.1. Remove all clothing contaminated
with electrolyte. If you cannot remove then
saturate in water.
1.6.2.2. Get medical assistance as soon as
possible. You must advise the medical staff of
the type acid.
1.6.2.2.1. Lead/acid battery = dilute
sulphuric acid
1.6.2.2.2. Nickel/cadmium = potassium

leads are NOT allowed to touch and cause a
spark. ALWAYS use suitable insulated tools.
1.7. Vibrations (where applicable).
1.7.1. Prolonged use of hand held (operated)
machines will cause the user to feel the effects
of/from vibrations. These vibrations can lead
to white finger (Raynaud's phenomenon) or
carpal tunnel syndrome. This condition
reduces the ability of the hand to feel and
regulate temperature, causing numbness and
heat sensations and may cause nerve damage
and circulatory tissue death.
1.7.2. Not all factors that lead to white finger
disease are known, but cold weather, smoking
and other diseases that affect blood vessels
and blood circulation as well as large and long-
lasting impact of shocks are considered factors
in the formation of white finger. Note the
following to reduce the risk the white finger
and carpal tunnel syndrome:
1.7.2.1. Wear gloves and keep your hands
warm
1.7.2.2. Take regular breaks
1.7.3. All of the above precautions may help
reduce the risk of white finger disease but not
rule out carpal tunnel syndrome. Long-term
and regular users are therefore recommended
to observe the condition of your hands and
fingers. Seek medical attention immediately if
any of the above symptoms should occur.
1.8. Noise (where applicable).
1.8.1. The operating noise of the machine
can damage your hearing. Wear hearing
protection such as earplugs or ear defenders
to protect your hearing. Long- term and
regular users are advised to have hearing
checked regularly. Be especially vigilant and
cautious when wearing hearing protection
because your ability to hear alarm warnings
will be reduced.
1.8.2. Noise emissions for this equipment is
unavoidable. Carry out noisy work at approved
times and for certain periods. Limit the
working time to a minimum. For your personal
protection and protection of people working
nearby it is also advisable for them to wear
hearing protection.

5. USING THE MACHINE
5.1. Trimming techniques.
If you are not familiar with this type of
machine you should practice in a safe
place.
5.1.1. ALWAYS clear the work area of
cans, bottles, rocks, etc. Flying or whirling
objects may cause serious injury and
damage to users or bystanders. If an
object is accidentally flung out from
machine, immediately stop and check the
machine
5.1.2. Always trim at high speeds.
5.1.3. Maneuverer the cutting head of
the trimmer horizontally from one side to
the other.
5.1.4. Keep cutting deck parallel with the
ground.
5.1.5. DO NOT tilt the nylon cutting head
during operation.
5.1.6. For correct cutting height carry out
a test trim in advance in a test area.
5.1.7. NEVER let the machine run with
damaged or defective parts.
5.1.8. Trimmer is to be used for trimming
grass only.
5.1.9. NEVER raise the nylon cutting head
above knee height during operation.
5.1.10. DO NOT use the machine on a
slope or uneven ground or if there is the
chance of slipping or losing the stability.
5.1.11. NEVER over cut instead cut short
lengths then cut successively lower
heights.
ALWAYS stop the machine before
removing grass deposits. To prevent
overheating of the drive axle remove all
tangled grass and weed fibre. The tangled
grass and weed fibre/s prevent the shaft
from cooling properly. Remove grass
deposits with a screwdriver or similar tool.
5.2. Trimming around trees.
5.2.1. Trim around trees carefully this will
prevent damage to the tree, and tree bark.
5.2.3. Move around the tree in a
clockwise direction. Approach grass/weeds

6. MAINTENANCE
Always stop the engine and unplug the spark plug before doing any repairs or maintenance.
Never touch the rotating nylon cord or blade.
Check and maintain fuel level regularly, and maintain the fuel/oil mix to the correct ratio.
Frequently check the brush cutter and make sure that all grass deposits are removed from
the trimmer head and trimmer guard.
At regular intervals, check the tightness of all nuts, bolts and screws.
If the blade hits an obstacle check for damage and if the machine vibrates badly stop the
lawnmower and take it to a service dealer.
Always refuel in a well-ventilated area with the engine off and spark plug HT cap removed.
Whilst carrying out maintenance you must wear appropriate Personal Protective Equipment
(PPE). Suggested PPE Sturdy footwear, work gloves (especially when working near cord cutter

6.1. Air filter.
Never let the engine run without the air filter being fitted. A dirty air filter element affects the
engine performance, increases fuel consumption and makes it difficult to start. If you notice a
loss of engine power.
6.1.1. Remove the air filter cover by pressing down on clip and pulling cover forward.
6.1.2. Carefully lower the outer cover.
6.1.3. Once the outer cover has been lowered you can remove the nylon gauze filter
element. If it is damaged replace it. Otherwise wash the element in clean soapy water, rinse
in fresh water and allow to fully air dry before replacing filter element.
N.B. To reinstate the fliter assembly reverse the above process.
Page 22
Ver 3 - September 2016

6.2. Spark plug.
The spark plug MUST be fully tightened otherwise the engine will overheat causing damage.
Always complete the following steps after the engine has been turned off and allowed to cool
down.
6.2.1. To make sure the engine runs correctly a spark plug gap of 0.6 -0.7 mm must be
maintained and the spark plug must be free of carbon deposits.
6.2.1. To remove the spark undo the cover then pull back the protective cover. Pull off the
HT lead and then undo the spark plug using the supplied box spanner in an anti-clockwise
direction.
6.2.3. Once the plug has been removed check it for visual damage, electrode wear and
carbon deposits. Replace a damaged or badly worn spark plug. Clean off any carbon deposits
by using a soft brass brush.
6.2.4. Check the gap with a feeler gauge and adjust electrode at the correct gap of 0.6 -0.7
mm.
6.2.5. Check the washer (replace as required) of the spark plug. Refit the spark plug by hand
to make sure it does not cross thread, tighten the spark plug to a torque of 12/15Nm.
6.2.6. To refit spark plug reverse the above process.

Manual’ is recommended.
6.4.2. Clean the outside of the machine, drive axle, shield and nylon cutting head.
6.4.3. Remove all fuel from the fuel tank, by undoing fuel cap and tipping content into a
suitable container. DO NOT use stale fuel/oil mixture in the next season.
6.4.4. After all the fuel has been removed from the fuel tank. Start the engine. Allow the
engine to run in idle until engine stops alone. This allows the fuel to be removed from the
carburetor.
6.4.5. Allow the engine to cool down for about five minutes.
6.4.6. Remove the spark plug and pour 1 teaspoon of clean 2-cycle oil into the combustion
chamber. Slowly pull the starter rope several times to coat internal components. Replace the
spark plug.
6.4.7. Store the machine in a cool, dry place away from any source of ignition such as an oil
burner, water heater etc.
