frequently.
The chain tension is correct when the gap between the 
cutter in the chain and the bar is between 3 mm - 4 
mm. Pull the chain in the middle of the lower side of the 
bar downwards (away from the bar) and measure the 
distance between the bar and the chain cutters.

3.  Tighten and lock the chain tension/guide bar locking 

knob by turning it clockwise.

Note:

 Make sure that the bar and chain tensioning 

assembly is moving freely without dirt and the saw 
chain is correctly looped around the sprocket. If the 
chain tension is too tight or too loose after locking 
the chain tension/guide bar locking knob, check if the 
guide bar and chain tensioning assembly are clean and 
properly assembled.
If necessary, remove the sprocket cover and guide bar 
for cleaning, then re-assemble the parts.

OPERATION

ADDING CHAIN LUBRICATING OIL

See page 269.

 WARNING

Never work without chain lubricant. If the saw chain is 
running without lubricant, the guide bar and saw chain 
can be damaged. It is essential to frequently check the 
oil level in the oil level gauge and before starting to use 
the chainsaw.

1. Clear surface around the oil cap to prevent 

contamination.

2.  Unscrew and remove the cap from the oil tank.
3.  Pour the oil into the oil tank and monitor the oil level 

gauge. Ensure that no dirt enters the oil tank while 
filling.

4.  Put the oil cap back on and tighten it up. Wipe away 

any spillage.

5.  One full oil tank will enable you to use the saw for 18 

- 28 min.

HOLDING THE CHAINSAW

See page 269.

Always hold the chain saw with your right hand at the rear 
handle and your left hand at the front handle. Grip both 
handles with the thumbs and 

fi

 ngers encircling the handles. 

Ensure that your left hand is holding the front handle so that 
your thumb is underneath.

 WARNING

Always keep the power cable tidy and away from the 
area of cutting. Apart from the danger of electrocution, 
untidy cables cause falls and trips.

STARTING THE CHAINSAW

See page 269.

1.  Connect the product to a power outlet. Make sure the 

chain brake is in the run position by pulling back on the 
lever/hand guard.

2.  To start the product: Press the trigger release, and then 

press the on/off trigger.

CHECKING AND OPERATING CHAIN BRAKE

1.  Engage the chain brake by rotating your left hand 

around the front handle. Allow the back of your hand to 
push the chain brake lever/hand guard toward the bar 
while the chain is rotating rapidly. The chain should stop 
rotating immediately. Be sure to maintain both hands on 
the saw handles at all times.

2.  Reset the chain brake back into the Run position by 

grasping the top of the chain brake lever/hand guard 
and pulling toward the front handle until you hear a 
click.

 WARNING

If the chain brake does not stop the chain immediately, or 
if the chain brake will not stay in the run position without 
assistance, have the product serviced by an authorised 
service centre prior to use.

REPLACING THE GUIDE BAR AND SAW CHAIN

See page 277 - 278.

1.  Disconnect the product from the power supply. Wear 

protective gloves.

2.  Unlock the chain tension/guide bar locking knob by 

turning it counterclockwise until the sprocket cover 
comes loose.

3.  Remove the sprocket cover. Remove the bar and saw 

chain from the product.

4.  Remove the screw holding the guide bar to the chain 

tension assembly. Dispose the used bar and saw chain 
properly.

5.  Mount the chain tension assembly on to the new bar 

and tighten the screw. Put the new chain in the correct 
direction onto the bar and make sure that the drive links 
are aligned in the bar groove.

6. 

Attach the bar to the chain saw and loop the chain 
around the drive sprocket.
Replace the sprocket cover.

7. 

Tighten and lock the chain tension/guide bar locking 
knob by turning it clockwise. 
The chain tension is correct when the gap between the 
cutter in the chain and the bar is between 3 mm - 4 
mm. Pull the chain in the middle of the lower side of the 
bar downwards (away from the bar) and measure the 
distance between the bar and the chain cutters.
Adjust the chain tension. Refer to the “Adjusting chain 
tension” section.

 WARNING

Improper chain sharpening increases the potential of 
kickback.

 WARNING

Failure to replace or repair a damaged chain can cause 
serious injury.
