RISK REDUCTION

It has been reported that vibrations from hand-held tools

may contribute to a condition called Raynaud’s Syndrome

in certain individuals. Symptoms may include tingling,

QXPEQHVVDQGEODQFKLQJRIWKH¿QJHUVXVXDOO\DSSDUHQW

upon exposure to cold. Hereditary factors, exposure to

cold and dampness, diet, smoking and work practices

are all thought to contribute to the development of these

symptoms. There are measures that can be taken by the

operator to possibly reduce the effects of vibration:

Ŷ Keep your body warm in cold weather. When operating

the product wear gloves to keep the hands and wrists

warm. It is reported that cold weather is a major factor

contributing to Raynaud’s Syndrome.

Ŷ After each period of operation, exercise to increase

blood circulation.

Ŷ Take frequent work breaks. Limit the amount of

exposure per day.

Ŷ Protective gloves available from professional chainsaw

retailers are designed specifically for chainsaw use and

give protection and good grip. Gloves also reduce the

effect of handle vibration. These gloves should comply

with EN381-7 and must be CE marked.

If you experience any of the symptoms of this condition,

immediately discontinue use and see your doctor.

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-kick-back 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 kick-back 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 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 product

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 kick-back. Only use replacement

guide bar and chain combinations recommended by the

manufacturer. The use of unrecommended guide 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

rotation. When the chain brake lever/hand guard is pushed

towards the bar, the chain should stop immediately. A

Chain brake does not prevent kick-back. It only lowers the

risk of injury should the chain bar contact the operators

body during a kick-back 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.
