EQUIPMENT CARE

To start a JONSERED
chainsaw...

Turn the ON / OFF switch
to ON, then pull the choke
control fully out to

automatically set the throttle to
the start position.

If the engine is warm, it may
start without any choke. I so,
just pull the choke control out to
set the throttle, then push it
back in.

Give the starter cord a few
firm, fast pulls and the
engine should now start.

Once started, squeeze the
throttle trigger and release
to leave the engine idling, then pull back the chain
brake handle as far as it will go.

Never work with the saw above shoulder height.
Adopt a stable, comfortable stance - one that gives a good

view of the cut - keeping the whole of your body clear of
the chain.

Squeeze the throttle trigger to bring the engine up to
maximum speed and cut vertically
downward or horizontally in a
straight line without forcing the saw

through the wood.

To help stop the saw ‘kicking back’
out of control, always cut with the
underside of the guide bar nearest
the saw body, keeping the front of
the saw body against the wood.

If felling a tree, do not cut lower
that 10” above soil level and never
use the saw to cut roots (this

includes stumps previously pulled from
the ground). Remember, soil is the chains worse enemy and
will blunt a chain in seconds.

NEVER cut with the tip or top edge of the guide bar.
Never let the chain touch the ground, nor any metal or
masonry obstructions. This may also cause kick-back
and will damage the blade.

If the saw does ‘kick-back’, the chain saw’s brake
automatically stops the chain, so, switch OFF the
engine immediately. Check the work to see what the
cause of ‘kick back’ was, then take all necessary steps to
ensure it doesn’t happen again. Reset the chain brake
before restarting (the chain will not move and the engines

clutch will be damaged if the chain break is not set).

If the guide bar gets trapped in a cut, switch OFF the
saw before freeing it. Don’t lever the bar free or you will
damage the saw.

Make sure you are clear of the saw as it clears the cut.
After finishing a cut, switch OFF before moving on to
another branch or tree.

BASIC TECHNIQUES

Don’t cut through branches that are under tension
unless you have been specially trained. Take your time
and don’t over do it. You are more likely to have an accident

if you are tired or rushing.

Keep your right hand on the throttle grip and your left
hand on the bar grip at all times.

Support small logs on a saw-horse or cradle before cutting.

When making a final felling cut to a tree, follow the
next few instructions carefully referring to the
illustration for additional guidance.

The top directional cut is made first, bringing the saw
downwards at 60 degrees to a depth

1

/

4 the diameter of

the trunk. Start high enough up the trunk to ensure you
have enough room for the bottom directional cut.
The bottom directional cut is made by bringing the saw
up at an angle of 30 degrees to meet the top cut. A
perfect directional cut has an angle opening of 90
degrees.
Next, the felling cut is made horizontally on the
opposite side at a level slightly higher than the tip of
the directional cut. The cut is made leaving at least
25mm to act as the hinge. When halfway through the
felling cut, insert a pry bar, or drive a wedge, into the
cut to prevent the saw being trapped.
When the cut is complete remove the chainsaw - turn it
off and put it down in a safe place.

CUTTING GUIDE

Quick Tip

Make a small cut on the underside of any branch

you want to lop, then cut down from the top to

remove it. Never try to cut right through a branch

from one direction or the saw will jam in the cut.

Never push the equipment beyond its design limits. If it

will not do what you want with reasonable ease and speed
assume you have the wrong tool for the job. contact your local
HSS Hire Shop.

When not in use, store the equipment with the chain bar
cover fitted, somewhere clean, dry and safe from thieves.

Regularly check the fuel level and top up as necessary

using 2-stroke oil and unleaded petrol mixed as directed on the
2-stroke oil sachet.

Use only non-fling chain oil to lubricate the guide bar.
Check the chain tension after the first 10 minutes use
and regularly thereafter. Always switch OFF and wait for the
chain to stop before doing this - always wear gloves. To
adjust the tension, slacken off the guide bar mounting
nuts, angle the bar upwards, then turn the tension screw
(inside edge of the bar) - clockwise to tighten the chain;
anti-clockwise to loosen it. Before restarting, re-tighten
the guide bar mounting nuts, double-check the chain

tension, then, wearing gloves, move the chain back and forth
along the guide bar by hand to make sure it revolves freely.

At the correct tension, the chain should be slack enough to

be moved by hand with four guide teeth visible above
the bar when pulled, yet tight enough to stay in contact
with the guide bar.

FINISHING OFF

Withdraw the guide bar from the cut and release the
throttle trigger.

Turn OFF the ON/OFF switch and wait for the chain to
stop before putting the tool down. Refit

the chain bar cover.
Let the engine cool then thoroughly clean the saw

ready for return to your local HSS Hire Shop.

footplate and hold the bar grip with your left hand

ready for starting.

To start a PARTNER CHAINSAW...
Turn the ON / OFF switch to ON, set the choke - fully

closed if starting from cold, half closed if the engine is warm ­then lock the throttle trigger half on using the lock

button.
Now, pull the starter cord a few times. Once the engine

has fired, fully open the choke, give the cord a further
pull and the engine should start.

If the engine floods, open the choke, lock the throttle full on,
then pull the starter cord a few times before re-trying the
normal starting procedure.

Finally, let the engine warm up, and release the throttle

trigger to leave the engine idling.

GENERAL SAFETY

Note that this safety wear is

cleaned and maintained by
HSS for your comfort.

Avoid loose garments and
jewellery that could catch in
moving parts. Tie back long

hair.

Make sure you understand
how to switch the chainsaw
OFF before starting it, in case
you get into difficulty.

Never use the chainsaw
unless there is someone
within earshot to summon
help in the event of an
accident.

Ensure the work area is well
lit and ventilated. Do not

work near flammable gases or
liquids.

Never use a chain saw if highly flammable vapours

petrol or paint thinner fumes for example - are present.

Always switch OFF the chain saw when not in use and

replace the protective sheath over the bar, never leave it
running and unattended.

Think before you cut. Work out where the tree or branch

will fall and clear the danger area. Remove trip hazards and

ensure you have a clear emergency escape route.
Watch your footing. Think twice before working anywhere

other than on firm, level ground. Never work in slippery or
wet conditions.

Never work above ground level unless you have been

specially trained for the job, not even from a ladder or steps.
And never work near overhead cables.
