LIMBING aND PRUNING

See figures 7 - 8.
This unit is designed for trimming small branches and
limbs up to 150 mm in diameter. For best results, observe
the following precautions.
■ Plan the cut carefully. Be aware of the direction in
which the branch will fall.
■ Branches may fall in unexpected directions. Do not
stand directly under the branch being cut.
■ The most typical cutting application is to position
the unit at an angle of 60° or less, depending on the
specific situation, as shown. As the angle of the pruner
shaft to ground increases, the difficulty of making the
first cut (from the underside of limb) increases.
■ Remove long branches in several stages.
■ Cut lower branches first to allow the top branches
more room to fall.
■ Work slowly, keeping both hands on the saw with a
firm grip. Maintain secure footing and balance.
■ Keep the tree between you and the chain while
limbing. Cut from side of tree opposite to the branch
you are cutting.
■ Do not cut from a ladder; this is extremely dangerous.
Leave this operation for professionals.
■ Do not make the flush cut next to the main limb or trunk
until you have cut off the limb further out to reduce
the weight. Following proper cutting procedures will
prevent stripping the bark from the main member.
■ Do not use the pruner for felling or bucking.
■ To prevent electrocution, do not operate within 15 m of
overhead electrical lines.
■ Keep bystanders at least 15 m away.

Before inspecting, cleaning or servicing the unit (except
for carburettor adjustments), shut off engine, wait for all
moving parts to stop, and disconnect spark plug wire
and move it away from spark plug. Failure to follow
these instructions can result in serious personal injury
or property damage.

GENERaL MaINtENaNCE

Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use.
Use clean cloths to remove dirt, dust, lubricant, grease,
etc.
Do not at any time let brake fluids, petrol, petroleum
based products, penetrating lubricant, etc., come in
contact with plastic parts. Chemicals can damage,
weaken, or destroy plastic, which may result in serious
personal injury
All pruner service, other than the items listed in the
instruction manual maintenance instructions, should
be carried out by an authorised service agent. To find
your nearest service agent please call the CUSTOMER
SERVICE CENTRE on 1300 361 505 or find it on our

CHaIN tENsION

See figures 13 - 14.
To avoid possible serious injury, never touch or adjust
the chain while the engine is running. The saw chain
is very sharp; always wear protective gloves when
performing maintenance to the chain.
■ Stop the engine before setting the chain tension. Make
sure the guide bar nut is loose to finger tight, turn the
chain tensioning screw clockwise to tension the chain.
Refer to Replacing the Bar and Chain for additional
information.
NOtE: A cold chain is correctly tensioned when there
is no slack on the underside of the guide bar, the chain
is snug, but it can be turned by hand without binding.
■ Chain must be re-tensioned whenever the flats (item
37) on the drive links hang out of the bar groove as
shown in figure 13.
