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.
ADJUSTING THE CHAIN TENSION
See page 25.
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
frequently.
The chain tension is correct when the gap between the
cutter in the chain and the bar is between 3 mm - 4
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.
OPERATION
ADDING CHAIN LUBRICATING OIL
See page 15.
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.
gauge. Ensure that no dirt enters the oil tank while
filling.
4.
any spillage.
5. One full oil tank will enable you to use the saw for 18
- 28 min.
HOLDING THE CHAIN SAW
See page 15.
Always hold the chain saw with your right hand on the rear
handle and your left hand on the front handle. Grip both
Ensure that your left hand is holding the front handle so
that your thumb is underneath.
