5 HEALTH & SAFETY INFORMATION
Felling
– Remove lower branches/limbs from the tree up to shoulder height.
– When removing the lower branches ensure the operator is protected from kickback by
using the tree stem for protection and keeping the guide bar out of
line with the body (off set).
– Ensure there is sufficient fuel in the tank to safely complete the felling cut.
– Never leave a partially felled tree.
– When the tree begins to fall, move back and away at 45º as quickly as possible. Branches on
the underside of the tree can cause the stem to move sideways or backwards dangerously.
– In the event of a tree becoming hung in another tree or obstacle seek assistance from a
professional. A hung tree poses many dangers and creates more potential risks than felling
a normal tree. Do not abandon a hung tree, walk under or attempt to climb one.
– Always perform a notch cut followed by a felling cut to create a felling hinge. Felling
wedges or levers may be necessary to prevent the chain saw from becoming pinched in the
felling cut.
Limbing
– Ensure the tree is stable before any limbering commences.
– The ideal working height for performing limbing is between waist and knee height.
– Stand on the left side of the stem, working from the root upwards, then return down the
other side.
– Use the top (pushing chain) and bottom (pulling chain) to make the cuts, constantly taking
note of the bar tip in conjunction with limbs further round the stem which may be less
visible or obscured.
– Ensure the tip of the bar does not come into contact with the ground.
– If the felled tree is on a slope always remain above the tree in case the removal of a limb
were to cause potentially dangerous movement.
– Rest the weight of the saw on the tree where possible.
– Take care of limbs and undergrowth under tension as there is a danger of spring back
once the cut has been performed.
– At regular intervals, stop the chain saw and clear the cut debris to maintain a firm footing.
Cross cutting
– The timber must be raised off the ground with supports to perform a safe cut.
– When working on slopes, always work above the timber in case of movement.
– Always adopt a good firm footing.
– Observe the timber to assess the surfaces for tension.
– Tension and compression in supported timber can result in the timber splitting or pinching
the guide bar if incorrectly cut.
– Alleviate tension in the timber by making an initial cut (1/3) into the compressed surface
before finishing the cut (2/3) into the tension surface.
– Stand off to the side of the saw in case of kickback.
– If the chain saw becomes trapped, switch off immediately before attempting to free the
guide bar. Use the correct tools when attempting to free a trapped saw
– Be ready to step back quickly in case of the timber rolling.
– Ensure no debris is present in the work area.
