Protective gloves available from professional chainsaw 
retailers are designed specifically for chainsaw use, 
which give protection, good grip and also reduce the 
effect of handle vibration.

If you experience any of the symptoms of this condition, 
immediately discontinue use and see your physician.

 WARNING

Injuries may be caused, or aggravated, by prolonged 
use of a tool. When using any tool for prolonged periods, 
ensure you take regular breaks.

SAFETY DEVICES

Low kick-back saw chain

A low-kickback saw chain helps to reduce the possibility of 
a kickback event.
The rakers (depth gauges) ahead of each cutter can 
minimize the force of a kickback reaction by preventing the 
cutters from digging in too deeply. Only use replacement 
guide bar and chain combinations recommended by the 
manufacturer.
As saw chains are sharpened, they lose some of the low 
kickback qualities and extra caution is required. For your 
safety, replace saw chains when cutting performance 
decreases.

Spiked bumper

The integral bumper spike may be used as a pivot when 
making a cut. It helps to keep the body of the chainsaw 
steady while cutting. When cutting, push the product 
forward until the spikes dig into the edge of the wood, then 
by moving the rear handle up or down in the direction of the 
cutting line it can help ease the physical strain of cutting

Guide bars

Generally, guide bars with small radius tips have somewhat 
lower potential for kickback. You should use a guide bar 
and matching chain which is just long enough for the job. 
Longer bars increase the risk of loss of control during 
sawing. Regularly check the chain tension. When cutting 

smaller branches (less than the full length of the guide bar) 
the chain is more likely to be thrown off if the tension is 
not correct.

Chain brake

Chain brakes are designed to quickly stop the chain from 
rotating. When the chain brake lever/hand guard is pushed 
towards the bar, the chain should stop immediately. A 
chain brake does not prevent kickback. It only lowers the 
risk of injury should the chain bar contact the operator’s 
body during a kickback event. The chain brake should be 
tested before each use for correct operation in both the run 
and brake positions.

Chain catcher

A chain catcher prevents the saw chain from being thrown 
back towards the operator if the saw chain comes loose 
or breaks.

ASSEMBLY

 WARNING

If any parts are damaged or missing, do not operate the 
product until the parts are replaced. Failure to heed this 
warning could result in serious personal injury.

ASSEMBLING THE SAW CHAIN AND GUIDE BAR

See page 268 - 269.

1.  Disconnect the mains plug. Wear protective gloves.
2.  Unscrew the guide bar locking knob and remove the 

sprocket cover.

3.  The saw chain should face in the direction of chain 

rotation. If they face backwards, turn the loop over.

4.  Place the chain drive links into the bar groove.
5.  Position the chain so there is a loop at the back of the 

bar.

6.  Hold the chain in position on the bar and place the loop 

around the drive sprocket. Lower the bar so that the 
bolt goes through the hole in the attached chain tension 
assembly.

7.  Replace the sprocket cover and then tighten the chain 

tension/guide bar locking knob by turning it clockwise 
until it locks into place. Check the chain tension 
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.

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

knob by turning it clockwise.

ADJUSTING THE CHAIN TENSION

See page 279.

1.  Disconnect the product from the power supply. Wear 

protective gloves.

2.  To correct the chain tension, fully loosen the chain 

tension/guide bar locking knob, then tighten the chain 
tension/guide bar locking knob by turning it clockwise 
until it locks into place. Check the chain tension
