■

A power spike causes voltage fluctuations and may
affect other electrical products in the same power
line. Connect the product to a power supply with an
impedance equal to or less than 0.33

to minimise

voltage fluctuations. Contact your electric power
supplier for further clarification.

■

Do not cut vines or small undergrowth (less than 75 mm
in diameter).

■

Before every use, examine the power cord for damage.
If the power cord is damaged, it must be replaced by
a qualified person at an authorised service centre to
avoid a hazard.

■

Electrical power should be supplied via a residual
current device (RCD) with a tripping current of not more
than 30 mA.

■

Make sure that the power cord is positioned so that it
cannot be damaged by the cutting means and will not
be stepped on, tripped over, or subjected to damage
or stress.

■

It is recommended to practise cutting logs on a saw-
horse or cradle when operating the product for the first
time.

■

The size of the work area depends on the job being
performed and the size of the tree or workpiece
involved. For example, felling a tree requires a larger
work area than making other cuts, such as bucking
cuts. The operator needs to be aware and in control of
everything happening in the work area.

■

Do not cut with your body in line with the guide bar and
chain. If you experience kickback, this position helps
prevent the chain from coming into contact with your
head or body.

■

Do not use a back-and-forward sawing motion. Let the
chain do the work. Keep the chain sharp, and do not try
to push the chain through the cut.

■

Do not put pressure on the saw at the end of the cut.
Be ready to take on the weight of the saw as it cuts free
from the wood. Failure to do so could result in possible
serious personal injury.

■

Do not stop the saw in the middle of a cutting operation.
Keep the saw running until it is already removed from
the cut.

■

To reduce the risk of injury associated with contacting
moving parts, always turn off the product, apply the
chain brake, disconnect the product from the power
supply, and make sure that all moving parts have come
to a complete stop:

●

before cleaning or clearing a blockage

●

before leaving the product unattended

●

before installing or removing attachments

●

before checking, conducting maintenance, or
working on the product

■

Injuries may be caused, or aggravated, by prolonged
use of the product. When using the product for
prolonged periods, ensure to take regular breaks.

■

If the product is dropped, suffers heavy impact, or
begins to vibrate abnormally, immediately stop the
product and inspect for damage or identify the cause of
the vibration. Any damage should be properly repaired
or replaced by an authorised service centre.

■

Operate the product only in temperatures between 0°C
and 40°C.

■

Store the product in a location where the ambient
temperature is between -10°C and 50°C.

PERSONAL PROTECTIVE EQUIPMENT

Good quality personal protective equipment, as used by
professionals, helps reduce the risk of injury to the operator.
The following items should be used when operating the
product:

■

Safety helmet

–

should comply with EN 397 and be CE marked

■

Hearing protection

–

should comply with EN 352-1 and be CE marked

■

Eye and face protection

–

should be CE marked and comply with EN 166 (for
safety glasses) or EN 1731 (for mesh visors)

■

Gloves

–

should comply with EN381-7 and be CE marked

■

Leg protection (chaps)

–

should comply with EN381-5, be CE marked and
provide all-round protection

■

Chainsaw safety boots

–

should comply with EN ISO 20345:2004 and be
marked with a shield depicting a chainsaw to show
compliance with EN 381-3. (Occasional users
may use steel toe-cap safety boots with protective
gaiters, which conform to EN 381-9 if the ground is
even and there is little risk of tripping or catching on
undergrowth)

■

Chainsaw jackets for upper body protection

–

should comply with EN 381-11 and be CE marked

INSTRUCTIONS CONCERNING THE PROPER
TECHNIQUES FOR BASIC FELLING, LIMBING,
AND CROSS-CUTTING

UNDERSTANDING THE FORCES WITHIN THE WOOD

When you understand the directional pressures and
stresses inside the wood, you can reduce the pinches or at
least expect them during your cutting. Tension in the wood
means the

bres are being pulled apart, and if you cut in this

area, the kerf or cut tends to open as the saw goes through.
If a log is being supported on a saw-horse and the end is
hanging unsupported over the end, tension is created on
the upper surface due to the weight of the overhanging log
stretching the

bers. Likewise, the underside of the log is

compressed and the

bres are being pushed together. If a

cut is made in this area, the kerf tends to close up during
the cut. This cut would pinch the blade.

PUSH AND PULL

The reaction force is always opposite to the direction the
chain is moving. The operator must be ready to control the
tendency for the product to pull away and push backwards.
The product pulls away (forward motion) when cutting on
the bottom edge of the bar. The product pushes backwards
(towards the operator) when cutting along the top edge.

SAW JAMMED IN THE CUT

Turn o

ﬀ

the product, and disconnect it from the power

supply. Do not try to force the chain and bar out of the
cut as this is likely to break the chain, which may swing
back and strike the operator. This situation normally occurs
