tensioned. Keep the spike or the saw body
against the wood when cutting. Use only
genuine accessories and spare parts. We
recommend you have your unit periodically
checked and serviced by an authorised
dealer. Do not use chainsaw above shoulder
height.
5 Do not operate the chainsaw near a naked
flame or spilled fuel. Only operate the
chainsaw outside and in well ventilated areas.
After re-fueling, always wipe off any spilled
fuel. Move the chainsaw away from the fueling
point before starting the engine.
6 Keep by-standers and animals out of the
work area; at a minimum distance of 10 m or
twice the timber length necessary, use
warning signs to keep on-lookers at a
distance.
Carefully survey the working site to note any
hazards, eg. roads, paths, electricity cables,
dangerous trees etc. Do not use the chainsaw
if the device stopping the chain (safety
chainbrake) does not work correctly.
Never place hands on the chain whilst the
engine is running.
Ensure someone is within hearing distance in
case of an accident. If this is not possible, it
is recommended that users operating
chainsaws in remote areas carry an adequate
first-aid kit with them and ensure someone
knows their location.
Never leave the engine running whilst the tool
is unattended.
ONLY USE ORIGINAL SPARE PARTS AND
ACCESSORIES.
BAR AND CHAIN
INSTALLATION
Ensure engine is always switched off before fitting
or adjusting chain. Wear a pair of protective gloves
when fitting or adjusting chain.
A . Clutch guard
B . Inner bar plate
C . Bar mounting bolts
D . Chain tensioning screw
E . Oil hole
F . Outer bar plate
G . Bar retention nuts
H . Sprocket
I . Adjusting screw
Remove the clutch guard (A) and the outer bar
plate (F). Check that the oil hole (E) is free from
impurities. Fit the chain over the sprocket (H).
Ensure correct direction of cutter tooth. Put the
bar in position over studs (C) slide it towards the
sprocket. Fit the chain into the bar groove and
slide the bar forwards.
Make sure that the tang chain tensioning screw
(D) fits into the hole in the bar (E). Replace the
outer bar plate and the clutch guard. Screw the
two bar retention nuts finger tight (G). Tension
the chain by turning the adjusting screw (I)
clockwise while raising the tip of the bar. The
tension is sufficient if the chain is snug on the bar
but still moves freely around the bar when pulled
by hand. Tighten the two bar retention nuts
securely.
Always use the combination tool to install and
tension the chain.
WARNING
Mount the bumber spike as shown in illustration.
RUNNING IN A NEW CHAIN
The chain must always be cold when carrying
out adjustment.
1 Let the chain run slowly for a few minutes.
Check that the oil pump is delivering oil onto
the chain.
2 Stop the engine and adjust the chain tension.
3 Check the tension of a new chain more
frequently during initial usage and adjust as
necessary.
4 Repeat adjusting until the chain does not
stretch any more.
Never touch the chain while the engine is running.
FUEL MIX
Use only fuel recommended by this manual. This
product is fitted with a 2-stroke engine and
therefore requires a 2-stroke petrol and oil mix.
Use leaded or unleaded petrol with a minimum
octane rating of 90. When using leaded petrol,
use 2.5% (40:1) of McCulloch oil, otherwise use
5% (20:1) of a high quality 2-stroke engine oil
(from a recognised brand). When using unleaded
petrol, use 2.5% (40:1) of McCulloch oil or use
2.5% (40:1) of a high quality synthetic 2-stroke
engine oil..
Only use oil from sealed containers. In order to
obtain a good fuel mix, put the oil into the
container before the petrol.
