Husqvarna M7 Chainsaw User Manual


 
Checking the chain
If the chain isn’t new, it’s probably a
good idea to file it, since cutting is both
easier and safer when the chain is sharp.
Also make sure the chain is tensioned
properly (1). Don’t forget that a new
chain should always be re-tensioned after
operating the saw for a short period (2).
Fuel
When filling the saw with fuel and
chain oil, place the saw on a stable surface.
To reduce dangerous emissions, choose
environmental petrol and vegetable-based
chain oil. The overfill protection helps
you avoid unnecessary spillage (3). And
considering the risk of fires, you should
always move the saw before starting it.
Safe distance
It’s good to work together with someone,
but make sure they are at least five metres
away when you start to use the saw. Of
course, when felling trees, this distance
should be increased considerably.
Start
When you’re ready to start, place the
saw flat on the ground and clear the area
around the bar.
1. Activate the chain brake by pushing
the kickback protection forward, as
otherwise the chain will start to rotate
when the saw starts.
2. Depress the SmartStart decompression
control, if the saw has this feature.
3. If the engine is cold, pull the choke
out fully.
4. Put your right foot partway through
the rear handle and hold the front handle
firmly with your left hand. Pull the starter
handle with your right hand until the
engine starts (4).
5. Now push the choke in again, with
the throttle on half way. Continue to pull
the starter handle until the saw starts.
Hit the throttle once so the engine speed
drops to idle. If the engine is already
warm, don’t use the choke, but the other
steps are the same.
If the saw is difficult to start despite
being warm, pull out the choke like you
do during cold starts, but push it back
in right away. When you’ve got the saw
started, don’t disengage the chain brake
until you’re ready to saw.
Checking the chain brake
Now check that the chain brake works.
Place the saw on a stable surface and
squeeze the throttle. Activate the chain
brake by pushing your left wrist against
the kickback protection, without
releasing the handle. The chain should
stop straight away. (5)
Does chain lubrication
work?
Also check the chain lubrication.
Hold the saw above a light surface,
such as a stump, and hit the throttle.
A line of oil should be visible on
the surface. (6)
Sawing practice
If you’re not used to using a chainsaw,
we recommend you first get acquainted
with the saw by practising a while on
a suitable log. (7)
How to operate the saw
There are some basic rules for using a
chainsaw. Hold it firmly by both handles
and hold your thumbs and fingers right
around the handles. Make sure you hold
your left thumb under the front handle,
to reduce the force of a possible kickback.
Good balance
It’s good to have respect for the saw,
but don’t be afraid of it. If you hold it
close to your body it won’t feel as heavy.
Also, you’ll be more balanced and in
better control of the saw. For the best
balance, stand with your feet apart. (7)
Pulling and pushing chain
You can saw with both the upper and
the lower edge of the bar. When using the
lower edge, you’re sawing with a pulling
chain, which means that the chain pulls
the saw away from you. Using the upper
edge of the chain, you’re sawing with
a pushing chain, so the chain pushes the
saw towards you.
Bend your knees
Save your back by not working with
a bent back. Instead, bend your knees
if you’re working at a low level.
Moving around
When moving around the worksite,
make sure the chain is not rotating by
activating the chain brake or turning
off the engine. For longer distances,
use the bar guard. (8)
Operating the saw.
Starting the saw is easy if you follow the instructions. But make sure you read the user’s manual for your saw
first, so you know how it works and are familiar with all its parts and controls.
