Use extreme caution when cutting brush and
saplings. The slender material may catch the saw
chain and be whipped toward you or pull you off
balance.
Carry the chainsaw by the front handle with the
chainsaw switched off and away from your body.
When transporting or storing the chainsaw always
fit the guide bar cover. Proper handling of the
chainsaw will reduce the likelihood of accidental
contact with the moving saw chain.
Follow instructions for lubricating, chain tensioning
and changing accessories. Improperly tensioned or
lubricated chain may either break or increase the
chance for kickback.
Keep handles dry, clean, and free from oil and
grease. Greasy, oily handles are slippery causing
loss of control.
Cut wood only. Do not use chainsaw for purposes
not intended. For example: do not use chainsaw for
cutting plastic, masonry or non-wood building
materials. Use of the chainsaw for operations
different than intended could result in a hazardous
situation.
CAUSES AND OPERATOR PREVENTION OF
KICKBACK
Kickback may occur when the nose or tip of the
guide bar touches an object, or when the wood
closes in and pinches the saw chain in the cut.
Tip contact in some cases may cause a sudden
reverse reaction, kicking the guide bar up and back
towards the operator.
Pinching the saw chain along the top of the guide
bar may push the guide bar rapidly back towards
the operator.
Either of these reactions may cause you to lose
control of the saw which could result in serious
personal injury. Do not rely exclusively upon the
safety devices built into your saw. As a chainsaw
user, you should take several steps to keep your
cutting jobs free from accident or injury.
Kickback is the result of tool misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
follows:
IMPORTANT SAFETY INSTRUCTIONS
Maintain a firm grip, with thumbs and fingers
encircling the chainsaw handles, with both hands
on the saw and position your body and arm to allow
you to resist kickback forces. Kickback forces can
be controlled by the operator, if proper precautions
are taken. Do not let go of the chainsaw.
Do not overreach and do not cut above shoulder
height. This helps prevent unintended tip contact
and enables better control of the chainsaw in
unexpected situations.
Only use replacement bars and chains specified by
the manufacturer. Incorrect replacement bars and
chains may cause chain breakage and/or kickback.
Follow the manufacturer's sharpening and
maintenance instructions for the saw chain.
Decreasing the depth gauge height can lead to
increased kickback.
ADDITIONAL CHAINSAW SAFETY WARNINGS
It is recommended to cut logs on a saw-horse or
cradle when operating the product the first time.
Ensure all guards, handles and spiked bumper are
properly fitted and are in good condition.
Persons using this chainsaw should be in good
health. The chainsaw is a heavy unit so the
operator requires to be physically fit. The operator
should be alert, have good vision, mobility, balance
and manual dexterity. If there is any doubt, do not
operate the chainsaw.
Do not start using the product until you have a
clear work area, secure footing, and a planned
retreat path away from the falling tree.
Beware of the emission of lubricant mist and saw
dust. Wear a mask or respirator if required.
Electric power should be supplied via a residual
current device (RCD) with a tripping current of not
more than 30 mA.
If the power cable becomes damaged, you must
return the machine to an authorised service centre
for repair or replacement.
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.
Do not cut vines and/or small undergrowth (less
than 75 mm in diameter).
