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, oil,
grease, etc.
Do not at any time let brake fluids, gasoline,
petroleum-based products, penetrating oils, etc.,
come in contact with plastic parts. Chemicals can
damage, weaken, or destroy plastic, which could
result in serious personal injury.
All pole saw/trimmer service, other than the items
listed in these maintenance instructions, should be
performed by competent pole saw/trimmer service
personnel.
POLE SAW MAINTENANCE
CHAIN TENSION
Never touch or adjust the chain while the motor is
running. The saw chain is very sharp; always wear
protective gloves when performing maintenance to the
chain.
Stop the motor and remove the battery pack before
setting the chain tension.
Make sure the chain cover knob, Fig.20 is loose to
finger tight. Use a hex key to turn the chain tensioning
allen screw clockwise to tension the chain, Fig.21.
Do not over-tension the chain as this will lead to
excessive wear and will reduce the life of the bar and
chain. Overtensioning also reduces the amount of cuts
you will get per battery charge.
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.
The chain must be re-tensioned whenever the flats,
Fig.22 (A) on the drive links hang out of the bar groove
as shown in Fig.22.
During normal operation, the temperature of the chain
will increase. The drive links of a correctly tensioned
warm chain will hang approximately .050 in. out of the
bar groove, as shown in Fig. 23.
REPLACING THE BAR AND CHAIN
Remove the battery pack before replacing the bar,
chain to avoid possible serious injury.
Remove the chain cover knob, Fig.20, by turning it in
a anticlockwise direction. Place the chain cover knob
to one side and then remove the chain cover from the
chainsaw.
The bar contains a slot, Fig.24 (A) that fits over the
mounting post, Fig.24 (B). The bar also contains a
chain tensioning pin hole, Fig.24 (C) which fits over
the chain tensioning pin, Fig.24 (D).
Place the bar onto the mounting post so that the
chain tensioning pin fits into the chain tensioning pin
hole.
NOTE: If necessary, rotate the chain tensioning allen
screw counterclockwise until the pin and hole can be
aligned. Fig.21.
Fit the chain, Fig.24 (E) over the sprocket, Fig.24 (F)
and into the bar groove. The cutters on the top of the
bar should face toward the bar tip, in the direction of
the chain rotation.
Replace the chain cover and tighten the chain cover
knob finger tight only.
The bar must be free to move for tension adjustment.
Remove all slack from chain by turning the chain
tensioning allen screw clockwise, assuring that the
chain seats into the bar groove during tensioning.
Tighten the chain cover knob securely.
NOTE: Chain is correctly tensioned when there is no
slack on the underside of the bar, the chain is snug,
but it can be turned by hand without binding. If chain
is too tight, it will not rotate. Loosen the chain cover
screw slightly and turn chain tensioning screw 1/4 turn
counterclockwise. Retighten chain cover screw
securely.
GUIDE BAR
Most guide bar problems can be avoided by keeping
the product well maintained. Incorrect filing and non-
uniform cutter and depth gauge settings cause most
guide bar problems, primarily resulting in uneven bar
wear. As the bar wears unevenly, the rails widen,
which may cause chain clatter and difficulty in making
straight cuts. Insufficient guide bar lubrication and
operating the product with a chain this is too tight will
contribute to rapid bar wear. To help minimise bar
wear, the guide bar maintenance is recommended.
When the guide bar is dismounted, remove any
sawdust from the “GROOVE“ in the guide bar rail.
Disassemble the saw chain and guide bar in reversed
order of assembly.
The circular groove of the guide bar will wear
particularly on the lower edge with time. When
replacing the chain turn the chain bar 180° to allow
even wear, thus extending guide bar life.
Rotate the guide bar occasionally to prevent uneven
wear. The guide bar ‘rail’ should always have a square
edge.
To check the guide bar “RAIL“ for wear: Hold a ruler
(straight edge) against the side of the guide bar and
“CUTTER SIDE PLATES“.
If there is a gap between the ruler and guide bar the
guide bar “RAIL“ is normal. If there is no gap (ruler
flush against the side of the guide bar) the guide bar
“RAIL“ is worn and needs to be replaced.
