Adjust the chain tension by turning the Chain Tensioner Screw in a clockwise direction, until the chain sits snugly to the bottom of the Guide Bar
Tighten both Guide Bar Nuts firmly
Check for smooth rotation of the Saw Chain.

Note: A new saw chain will expand when first used. Check and readjust chain tension frequently to avoid premature wear, damage and kickback.

Preparing 2-stroke mix

This chainsaw is powered by a 2-stroke engine that requires a petrol/oil mixture as fuel. Always use dedicated 2-stroke oil. Measure the required amount of oil and pour the required amount of unleaded petrol into the Fuel Mixing Bottle (30), close and shake until thoroughly mixed. Never fill with fuel whilst the engine is running. Only refuel your chainsaw outdoors, in well-ventilated areas. Fuels containing more than 10% ethanol must not be used under any circumstances. Be careful not to spill any fuel. Spilled fuel may ignite and cause fires or explosions.

Clean the area around the cap of the Fuel Tank
Fill the Fuel Tank with fresh 2-stroke mix. Do not overfill
Immediately refit the cap to the tank, and close Move at least 3m from the fuelling spot before attempting to start the engine.

Filling with chain oil

Be careful not to spill any oil. Be aware of slipping hazards!

Clean the area around the cap of the Chain Oil Reservoir (14)
Fill with special chain oil. Do not overfill
Immediately refit the Chain Oil Reservoir cap

Testing the chain brake

The operator must ensure the correct operation of chain brake before every use.

Make sure the engine has stopped
Check manual chain brake operation by pushing the Front Hand Guard (3) forward. The Saw Chain must not turn
Release the chain brake by pulling the Front Hand Guard towards to Front Handle (15), until a ‘click’ sound is heard.
Hold the chainsaw horizontally, release your hand from the Front Handle and let the tip of the Guide Bar hit a tree stump or other piece of wood on the floor. The chain brake must engage, and the Saw Chain must not move.

Operation

Starting and stopping the engine

Activate the chain brake by pushing the Front Hand Guard (3) forward
Toggle the Engine Switch (7) upward into the ‘On’ position
Press the pump (primer) (33) ten times
Pull out the Choke Lever (8)
Put the chainsaw on the floor on to a flat surface. Ensure that the Saw Chain (2) is not in contact with the ground or any object
Place your left hand on the Front Handle (15) and push down
Push your right toe cap into the Rear Handle (10), to hold the chainsaw in place
Grab hold of the Recoil Starter (4) handle and slowly pull the Recoil Starter outward, until you feel resistance, then pull sharply a few times, until the engine fires briefly, but dies again immediately
Push in the Choke Lever
Pull the Recoil Starter again, until the engine starts
Slowly remove your foot from the Rear Handle and pick the tool up on the Front Handle
To switch off the engine, toggle the Engine Switch downward, into the ‘STOP’ position

Starting an engine flooded with fuel

Remove the Air Cleaner Cover (5) and Air Cleaner
Pull the Spark Plug Cap (23) off the Spark Plug
Remove the Spark Plug (24)
If the spark plug is fouled, encrusted or soaked with fuel, clean and adjust it. Replace if required
Clean excess fuel from the combustion chamber by slowly pulling the Recoil Starter (4)
Reinstall the Spark Plug
Repeat the starting procedure

Checking chain lubrication

After starting the engine, the chainsaw operator needs to ensure that sufficient oil is delivered to lubricate the chain

With the engine running, disengage the chain brake
Hold the chainsaw firmly with both hands, and direct the Guide Bar towards the ground
Disengage the Throttle Interlock (12) and press the Throttle Trigger (11)
Run the chainsaw at medium speed. Oil should be scattered off the chain, onto the floor

Potentially dangerous reactive forces may occur any time the chain is rotating. These reactive forces may result in loss of control which may, in turn, cause serious or fatal injury.

Pull-in occurs when the Saw Chain (2) on the underneath of the Guide Bar (1) suddenly stops, for example when caught on a foreign object inside the wood. The saw is pulled forward, and may cause the operator to lose control of the chainsaw.

Always wait until the chain has reached its full cutting speed, before starting cutting
Ensure the Bumper Spikes (20) engage the wood properly
Use wedges to open up existing partial cuts

Push-back occurs when the Saw Chain (2) on top the Guide Bar (1) suddenly stops, for example when pinched. The saw is viscously pushed backwards towards the operator, potentially causing him to lose control over the chainsaw.

Avoid cutting situations that may cause material to pinch the top of the Saw Chain
Do not cut more than one object at a time
Do not twist the saw when pulling the bar out of a plunge or underbuck cut

Kickback may occur when the nose of the Guide Bar is pinched unexpectedly or is incorrectly used to begin a plunge cut.

Hold the chainsaw firmly with both hands
Always stand to the side of the cutting path
Do not use the tip of the Guide Bar for cutting
Do not overreach or cut above shoulder height
Always wait until the Saw Chain has reached its maximum cutting speed, before cutting
Only ever cut one log at a time
Be extremely careful when you have to re-enter a previously made cut

Transporting the chainsaw

Always switch off the engine before putting a chainsaw down or transporting it. Wait until the engine has cooled completely.
Always fit the Safety Cover (31) to the Guide Bar (1) before transporting the chainsaw. Carry the saw on its Front Handle (15), with the bar pointing backwards.

Cutting instructions

Tree felling should only be undertaken by people with sufficient expertise and training.
Always maintain secure footing. Never work from a ladder or use the saw above shoulder height.
Never work from inside a tree, unless you have been specifically, professionally trained.
Never put the chainsaw down and leave it with the engine running.
Hold the Front Handle (15) with your left hand, and the Rear Handle (10) with your right hand (this position should also be adopted by left-handed operators).

Cleaning and maintenance

Always switch the chainsaw off and wait until all components have completely cooled, before carrying out any maintenance. This chainsaw must only be serviced by people with the necessary competence and skill level. Attempting maintenance or repairs not covered by this manual will void the warranty.

Keep your tool clean at all times. Clean the body of your machine with a soft brush, or dry cloth.
Use a mild detergent and a damp cloth to clean parts contaminated with oil or fuel. Rinse with fresh water and dry thoroughly.
Clean the chain, bar and sprocket after every use.
Lubricate moving parts after cleaning.
The Saw Chain (2) must be sharpened regularly.
Make sure you inspect and clean the air cleaner, fuel, and oil filter on a regular basis.

Adjusting chain oil delivery

Chain oil delivery can be adjusted by inserting the supplied slotted screwdriver (28) into the chain oil adjustment screw at the bottom of the tool
Increase or decrease chain oil delivery as required by working conditions.

Adjusting chain tension

Always wear cut-proof gloves when touching the saw chain, to avoid injury.

Loosen the Guide Bar Nuts (22)
Adjust the Chain Tensioner Screw (21):
- turn clockwise to increase chain tension
- turn anticlockwise to decrease chain tension
Tighten the Guide Bar Nuts securely
Check chain tension

Maintaining the spark plug

Never test the ignition system with an unseated spark plug or the ignition wire removed from the spark plug (24). Uncontained sparking may ignite fuel and cause a fire.

Remove the Air Cleaner
Pull the Spark Plug Cap (23)
Clean any dirt from the Spark Plug Cap or the top of the Spark Plug
Loosen and remove the Spark Plug
Visually inspect the Spark Plug and electrodes. Discard if you detect any damage
If any deposits are visible around the electrode area, brush off with a brass wire spark plug brush (not included)
Reinstall the Spark Plug and tightened
Push fit the Spark Plug Cap, refit the Air Cleaner and Air Cleaner Cover.

Storage

Store carefully in a secure, dry place out of the reach of children. Fit the Safety Cover (31) over the Guide Bar (1) and Saw Chain (2) for storage. Whenever the chainsaw is out of use for an extended period of time, proceed as follows

Give the unit an overall cleaning and check
Drain the fuel system
Remove the Spark Plug (24), fill about a spoonful of 2-stroke oil into the cylinder through the spark plug hole, and pull the Recoil Starter (4) gently two to three times to distribute the oil evenly. Replace the Spark Plug
Slowly pull the Recoil Starter just until resistance is felt. At this point both the intake and exhaust valves are closed. Storing the engine in this position will help prevent internal corrosion
Protect all metal parts from corrosion by coatingthem with oil or a machinery preservative

Storing fuel

Store 2-stroke mix only in containers specifically designed for fuel storage. Store fuel in a dark place with a constant, low temperature.
