Kickback Safety Precautions – Chainsaw
DANGER
• Kickback may occur when the nose or tip of the guide bar touches an object, or
when the wood closes in and pinches the chainsaw in the cut. Tip contact in
some cases may cause a lightning fast reverse reaction, kicking the guide bar
up and back towards the operator. Pinching the saw chain along the top of the
guide bar may push the guide bar rapidly back towards the operator. Either of
these reactions may cause you to lose control of the saw, which can result in
serious personal injury.
• Do not rely exclusively on the safety devices built into the saw. As a chainsaw
user, you should take several steps towards keeping cutting jobs free from
injury or accidents.
• With basic understanding of kickback, you can reduce or eliminate the element of
surprise. Sudden surprises contribute to accidents.
• Keep a good grip on the saw with both hands, with your right hand on the rear
handle and your left hand on the front handle when the engine is running. Use a
firm grip with thumbs and fingers encircling the chainsaw handles. A firm grip will
help you reduce kickback and maintain control of the saw.
• Make certain that the area in which you are cutting is free from obstructions. Do
not let the nose of the guide bar contact a log, branch or any other obstruction
which could be hit while you are operating the saw.
• Cut while the engine is at high speed.
• Make sure the chain and guide bar are correctly adjusted before operating the
equipment. Never attempt chain adjustments with the engine running!
• Always make sure the cutting attachment is properly installed and firmly
tightened before operation.
• Never use a cracked or warped guide bar; replace it with a new one and make
sure it fits correctly.
• If a saw blade should bind fast in a cut, shut off the engine immediately. Push the
branch or tree to ease the bind and free the blade.
• Do not operate the pole pruner with the muffler removed.
• When cutting a limb that is under tension, be alert for spring-back so that you will
not be struck by the moving limb.
• Always stop the engine immediately and check for damage if you strike a foreign
object or if the machine becomes tangled. Do not operate with broken or
damaged equipment.
• Do not make unauthorised modifications or substitutions to the guide bar or
chain.
• Never allow the engine to run at high speeds with a load. Doing so could damage
the engine.
• Keep the pruner as clean as possible. Keep it free from loose vegetation, mud, etc..

OPERATIONS
Before Use Checks
WARNING!
For your safety and to maximise the service life of the equipment, it is very important
to take a few moments before you operate the engine to check its condition. Be sure to
take care of any problems you find, or contact the Kogan customer support team to
have them assess it for you.
Before beginning the pre-operation checks, be sure that the switch is in the OFF
position.
Always check the following items before you start the engine:
• Cutting head is mounted correctly
• Switches move easily and work correctly
• The ignition plug is safely mounted (If the plug is loose, sparking and subsequent
ignition of the fuel vapours may occur.)
• Hand-grips are clean, dry and steady
• Cutting head must move freely
DANGER!
If in doubt as to the safe working methods when using any of the attachments, take
advice from a professional gardener or contact the service center.
Non-professional advice may be dangerous to life.
Fuel and Chain Oil
DANGER!
Fuel is extremely flammable. Avoid smoking or bringing any flames or sparks near fuel.
Make sure to stop the engine and allow it to cool before refuelling the unit. Select bare,
flat ground outdoors for fuelling, and then move at least 3 metres away from the fuelling
point before starting the engine.
14
FUEL
•
•
•
•
•
•
Mix unleaded petrol with air-cooled 2-stroke engine oil at a ratio of 25:1
These engines are certified to run on unleaded fuel.
Make sure to use petrol with a minimum octane level of 93RON.
If you use petrol with a lower octane value than prescribed, there is a danger that
the temperature may rise and piston seizing may occur.
Unleaded petrol is recommended to reduce contamination in the air for the sake
of health and the environment.
Poor quality fuel or oil may damage sealing rings, fuel lines or the fuel tank.
CHAIN OIL
• Use motor oil SAE #10W-30 all year round, or SAE#30~#40 in summer, and SAE
#20 in winter.
Safe Operating Precautions
Before operating the engine for the first time, please review the SAFETY INFORMATION
and the BEFORE OPERATION CHECKS!
• Hold equipment firmly and safely with both hands at all times!
• Work thoughtfully and do not expose anybody to risk while in operation. Be calm
and considerate when working.
• Do not work unless the visual and lighting conditions are good.
• Keep your eye on the cutting head at all times!
• Never work while standing on a ladder.
• Work on firm and stable ground or flooring at all times!
• In the course of work procedure, make sure that no people or animals are
standing with a 10 metre diameter. Switch the unit off immediately if anybody
enters within the reach of the unit.
• Use unit during daytime only.
Starting the Engine
1 – Feed fuel into the fuel tank and tighten the cap securely. (For the Pole chainsaw, also
feed chain oil into the oil tank and tighten the cap securely.)

5 – Set the stop switch to the “START” position. Press down the throttle lock.
6 – While holding the unit firmly, pull the starter rope quickly until the engine fires up. Be
sure to keep the head clear of all nearby objects still.
7 – Move the choke lever down towards the open position.
WARNING!
The product is equipped with a centrifugal clutch mechanism, so the cutting attachment
will begin to rotate as soon as the engine is started by putting the throttle into the start
position. When starting the engine, place the product onto the ground in a flat clear area
and hold it firmly in place to ensure that the cutting parts nor the throttle come into
contact with any obstacles when the engine starts.
Do not pull the cord too far. Watch the cutting head while pulling the starter cable.
16
8 – Allow the engine to warm up for several minutes before starting operations.
NOTES
• When restarting the engine immediately after stopping it, leave the choke open.
• Over-choking can make the engine hard to start due to excess fuel. When the
engine fails to start after several attempts, open the choke and repeat pulling the
rope, or remove the spark plug and dry it.
Stopping the Engine
1 - Release the throttle lever and run the engine for half a minute.
2 - Shift the stop switch to the STOP position.
WARNING!
• Except in an emergency, avoid stopping the engine while pulling the throttle lever.
• When engine doesn't stop with use of the stop switch, move the choke level to
the closed position.
OPERATING THE POLE SAW
DANGER!
• Always wear work gloves made of leather or some other sturdy material when
using the pole saw.
• Falling branches may fall onto your face or into your eyes, resulting in injuries,
scratches and cuts. For this reason, you should always be sure to wear a helmet
and face protection when using the pole saw.
Checking the Oil Supply
After starting the engine, run the chain at medium speed to see if chain oil is scattered
off, as shown in the image.
The oil reservoir has capacity to provide about 40 minutes of cutting time (when set to
deliver the minimum flow rate, or about as long as it will take to use a tank of fuel). Be
sure to refill the oil tank every time you refuel the saw.
Adjusting Oil Flow Rate
CAUTION!
Never fill the oil reservoir, nor adjust the oiler with the engine running.
An increase in bar oil flow rate will speed oil consumption, requiring more frequent
checks on the oil reservoir. To ensure sufficient lubrication, it may be necessary to check
the oil level more frequently than fuel tank refills.
The guide bar and chain are lubricated automatically by a pump that operates whenever
the chain rotates. The pump is set at the factory to deliver a minimum flow rate, but it
can be adjusted. A temporary increase in oil flow is often desirable when cutting things
like hardwood, or wood with a lot of pitch.
17
Adjust the pump as follows:
1 – Stop the engine and make sure the stop switch is in the OFF position.
2 – Place the unit on its side with the oil reservoir up.
3 – With a screwdriver, push in on the oil flow rate adjusting screw and turn in the
desired direction.
CAUTION!
The oil flow adjusting screw must be pressed in slightly in order to turn. Failure to do so
could damage the pump and the screw.
OPERATING THE POLE HEDGE TRIMMER
DANGER!
This product is equipped with extremely sharp blades, and when used improperly these
blades can be extremely dangerous. Improper handling can cause accidents which may
in turn lead to serious injury or death. For this reason, you should always be careful to
follow the following instructions when using the pole hedge trimmer.
•
•
•
•
•
•
Never hold the trimmer in a way in which the blades are pointed towards
somebody else.
Never allow the blades to come into close proximity with your body while the
engine of the trimmer is in operation.
Always be sure to turn the engine off before changing the angle of the blades,
removing branches which have become stuck in the blades, or at any other time
when coming into close contact with the blades.
Always wear work gloves made of leather or some other sturdy material when
using the trimmer.
Always place the blade cover provided with the trimmer over the blades when not
in use.
Falling branches may fall onto your face or into your eyes, resulting in injuries,
scratches and cuts. For this reason, you should always be sure to wear a helmet
and face protection when using the trimmer.
CAUTION!
The thickness of branches which may be cut with this trimmer is limited to up to
approximately 5mm (3/16”). Never try to cut branches thicker than this, as doing so may
result in damage to the trimmer.
18
Adjusting the Angle of the Cutting Blades
1 – Stop the engine.
2 – Lift the lock lever and press down on the adjusting lever.
3 – Adjust the angle of the blades to the desired angle then release the lever.
OPERATING THE BRUSH CUTTER
•
•
•
To turn the machine off, the switch must be in the “STOP” position.
Prior to using the brush cutter, remove all hard objects (stones, metal parts etc..)
from the working area. The cutter may strike them, causing them to cause
personal or material damage.
When working in high shrubs or bushes, the working height must be at least 15cm
from the ground as a minimum to protect small animals from danger.
When working in grass areas, hold the cutter at an angle of approximately 30 and make
semicircular turns to your right and left.
The best results are achieved from grass 15cm high. If higher, you may need to repeat
the cutting several times.
Be sure to NEVER putting the cutting head on the ground while the engine is running.
Extending the Cutting Fibre
•
•
Hold the running machine over the grass, then knock the ground several times
with the mowing head to release the fibre, which will lengthen.
The cutter enclosed in the protection shield will cut the fibre to the required
length.
If unit is vibrating heavily, turn the unit off and allow it to cool. Remove all loose grass
stuck in the mowing head and around the protection shield.
Never replace the plastic cutting fibre with steel wire. There is extreme risk of injury and
damage as this unit is not designed to be used with a metal cutting fibre.
19
MAINTENANCE
Good maintenance is essential for safe, economical and trouble-free operation.
It will also help to reduce pollution.
DANGER!
Improper maintenance, or failure to correct a problem before operation can cause a
malfunction in which you may be seriously hurt or killed.
Always follow the inspection and maintenance recommendations and schedules in this
owner's manual.
To help you properly care for your equipment, the following pages include a

engine failing to operate properly, or with the engine becoming overheated and
damaged.
• To install the spark plug, first turn the plug until it is finger tight, then tighten it a
quarter of a turn more with a socket wrench.
Tightening torque: 9.8 ~ 11.8 N.m (1 ~ 1.2kg.m)
Muffler
WARNING!
• Inspect the muffler periodically for loose fasteners, damage or corrosion. If any
sign of exhaust leakage is found, stop using the machine and have it repaired
immediately.
• Note that failing to maintain the muffler may result in the engine catching fire.
Remove the muffler, insert a screwdriver into the vent, then wipe away any carbon buildup. Wipe away any carbon build-up on the muffler exhaust vent and cylinder exhaust
port at the same time.

HEDGE TRIMMER CARE
Blade
•
•
1.
When refilling the tank or resting, it is often a good idea to use the time to oil the
cutting blades.
If a gap exists between the upper and lower blades, follow the procedure below to
adjust them so that they fit closer together.
Loosen lock nut (A) as shown in the diagram.
2. Tighten screw (B) fully, then turn one-third of one half of a rotation backward.
3. While holding onto the screw to keep it in position, tighten the lock nut.
4. Check to make sure that the flat washer (C) is loose enough so that it may be
turned by pressing on it.
NOTE: Screwing the screw in too tight may make it impossible for the blades to move.
Conversely, not screwing it tightly enough may make the blades of the trimmer feel dull
and cause leaves and branches to become caught in the blades of the trimmer.
TIP: If the blades become so worn down that it is no longer possible to eliminate the gap
between them, you should contact a professional to resharpen them.
Transmission
The reduction gears are lubricated by multi-purpose grease in the transmission.
Apply new grease every 25 hours of use, or more often depending on the job condition.
When adding lubricant, use a grease gun to insert lubricant into the three grease nipples
located on the transmission.

POLE CHAINSAW CARE
Oiling Port
Dismount the guide bar and check the oiling port for clogging.
Oiling Port
Guide Bar
Remove sawdust in the bar groove and the oiling port.
Groove
Oiling port
The bar rail should always be a square. Check for wearing of the bar rail. Apply a ruler to
the bar and the outside of the cutter. If a gap is observed between them, then the rail is
normal. Otherwise, the bar rail is worn and needs to be corrected or replaced.

No Gap
Note in the bottom situation, the chain is tilting.
This is a sign that the bar is worn.

Sprocket
Check for extensive wear, and replace it when the teeth are worn over 0.3mm.
Sprocket
Saw Chain
CAUTION!
It is very important for smooth and safe operation to keep the cutters always sharp.
Your cutters need to be sharpened when:
• Sawdust becomes powder-like
• You need extra force to saw in
• The cut does not go straight
• Vibration increases
• Fuel consumption increases
Cutter Setting Standards
WARNING!
Be sure to always wear safety gloves when handling the cutting chain.
Before filing:
• Make sure the chain is held securely.
• Make sure the engine is stopped.
• Use a round file of proper size for your chain.
• Chain type: 91PJ
• File size: 5/32” (4.0mm)
Place your file on the cutter and push straight forward.
Keep the file in position, as illustrated below.
24
After every cutter has been set, check the depth gauge and file it to the proper level as
illustrated.
Note: Be sure to round off the front edge to reduce the chance of kickback or tie-strap
breakage.
Make sure every cutter has the same length and edge angles as illustrated.

Transmission
The reduction gears are lubricated by multi-purpose, lithium-based grease in the
transmission. Apply new grease every 25 hours or more often depending on the job
condition. When adding lubricant, use a grease gun to insert lubricant into the three
grease nipples located on the transmission.

STORAGE
Aged fuel is one of the major causes of engines failing to start. Before storing the unit, empty the
fuel tank and run the engine until is uses all the fuel left in the fuel line and the carburettor.
Clean and carry out maintenance checks on the unit before storing.
Store the unit indoors, taking necessary steps to prevent rust prevention.
DISPOSAL
When disposing of the machinery, fuel or oil for the machine, please contact your local council for
advice on the best methods to ensure that there is no negative impact on the environment.
