Avoid working under over-hanging embankments or
stockpiles
that could collapse onto the machine.
Reduce the machine speed when travelling over
ground when obstacles may be hidden (for example,
through snow or uncleared undergrowth). Hitting
obstacles (boulders, stumps) can cause a sudden stop,
so always wear a safety belt.
Avoid risks in difficult conditions. If operating in
strong winds, or dealing with trees that are leaning over
or hard to reach, take care and take your time. Do not
take unnecessary risks

Saw chain shot hazard zone
Chain shot is the high velocity separation and ejection of
a piece or pieces from the end of a broken saw chain
during mechanised timber harvesting.
CAUTION: Saw chain shot can expose machine
operators and bystanders to the risk of death or
serious injury.
Chain shot pieces typically travel within 15 degrees on
either side of the saw bar plane. A chain shot consists of
two breaks in a saw chain. First, the saw chain loop
breaks and forms two ends. One end moves past the
saw chain drive sprocket or saw bar tip and is rapidly
accelerated due to motion of the saw chain end. The
whip action causes a second break in the saw chain,
ejecting pieces of the cutting saw chain at high speed.
To reduce the occurrence of chain shot:
● Follow recommendations for saw unit maintenance
and adjustments. Inspect the saw chain and cutting
system frequently. Replace damaged parts using
approved replacements.
● Keep saw chains sharp and lubricated. Do not
exceed the maximum recommended saw speed.
Check hydraulic oil pressure and flow rate to the saw
unit after any carrier hydraulic system repairs.
● Discard the saw chain after the second break.
To reduce the risk of injury from chain shot:
● Operators and bystanders should never be exposed
to the chain shot hazard zone when the saw chain is
in motion.
● All machines in the chain shot hazard zone should be
fitted with protective guards, shields, and windows in
accordance with forestry operation safety standards
and regulations.(Polycarbonate windows are
recommended.)
● Inspect the cabin window regularly, and after every
impact. Replace the window if it is damaged, cloudy,
or has visible micro-cracking or crazing.
● Inspect the chain shot guard (if equipped) each time
the saw chain is replaced. Replace the chain shot
guard if it is missing or damaged.
