chain is bent or damaged, replace it. Check all
control levers and switches for easy action.
Clean and dry the grips.
4. Never attempt to start the tool if the tool is
damaged or not fully assembled. Otherwise
seriousinjurymayresult.
5. Adjust the shoulder harness to suit the opera-
tor’s body size.
6. Adjust the chain tension properly. Rell the
chain oil, if necessary.
Starting the tool
1. Wear the personal protective equipments
before starting the tool.
2. Before starting the tool, make sure that there
is no person or animal in the work area.
3.
When installing the battery cartridge, keep the
saw chain and guide bar clear of your body and
other object, including the ground. The saw chain
may move when starting and may cause serious
injuryordamagetothesawchainand/orproperty.
4. Place the tool on rm ground. Maintain good
balance and secure footing.
Operation
1. In the event of an emergency, switch o󰀨 the
tool immediately.
2. If you notice any unusual condition (e.g. noise,
vibration) during operation, switch o󰀨 the tool.
Do not use the tool until the cause is recog-
nized and solved.
3. The saw chain continues to move for a short
period after switching o󰀨 the tool. Don’t rush
to contact the saw chain.
4. During operation, use the shoulder harness.
Keep the tool on your right side rmly.
5. Hold the front grip with your left hand and the
rear grip with your right hand, no matter you
are right-hander or left-hander. Wrap your
ngers and thumbs around the grips.
6. Hold the tool by insulated gripping surfaces
only, because the saw chain may contact hid-
den wiring. A saw chain contacting a “live” wire
may make exposed metal parts of the extend-
ed-reach pruner “live” and could give the operator
an electric shock.
7. Never attempt to operate the tool with one
hand. Loss of control may result in serious or
fatal injury. To reduce the risk of injury, keep
your hands and feet away from the saw chain.
8. Do not overreach. Keep proper footing and
balance at all times. Watch for hidden obsta-
cles such as tree stumps, roots and ditches
to avoid stumbling. Clear fallen branches and
other objects away.
9.
Never work on a ladder or tree to avoid loss of control.
10. If the tool gets heavy impact or fall, check the
condition before continuing work. If there is
any damage or doubt, ask Makita authorized
service center for the inspection and repair.
11. Do not touch the head of the tool. The head of
the tool becomes hot during operation.
12. Take a rest to prevent loss of control caused
by fatigue. We recommend to take a 10 to
20-minute rest every hour.
13. When you leave the tool, even if it is a short
time, always switch o󰀨 the tool and remove the
battery cartridge. The running and unattended
tool may be used by unauthorized person and
cause serious accident.
14. When operating the tool, do not raise your
right hand above your shoulder height.
15. During operation, never hit the saw chain
against hard obstacles such stones and nails.
Take particular care when cutting branches
next to walls, wire fences or the like.
16.
If branches get caught in the tool, always stop the
tool and remove the battery cartridge. Otherwise
unintentionalstartmaycauseseriousinjury.
17. If the saw chain becomes clogged, always
switch o󰀨 the tool and remove the battery
cartridge before cleaning.
18. Accelerating the tool with the saw chain
blocked increases the load and will damage
the tool.
19. Before cutting limbs, keep an escape area
away from the falling limb. First, clear
obstructs such as limbs and branches from
the work area. Move all tools and goods from
the escape area to another safe place.
20. Before cutting branches and limbs, check
the falling direction of them, considering the
condition of branches and limbs, adjoining
trees, wind direction, etc. Pay full attention to
the falling direction, and the rebound of the
branch, which hit the ground.
21. Never hold the tool at an angle of more than
60°. Otherwise falling objects can hit the oper-
ator and cause serious injury. Never stand
underneath the limb being cut.
22.
Pay attention to broken or bent branches. They may
bouncebackincutting,causingunexpectedinjury.
23. Before cutting limbs that you intend to cut,
remove branches and leaves around them.
Otherwise the saw chain may be caught by them.
24. To prevent the saw chain from being caught in
the kerf, do not release the lever before pulling
the saw chain out of the kerf.
25. If the saw chain is bound in the kerf, immedi-
ately stop the tool, carefully move the branch
to open the kerf and release the saw chain.
26. Avoid kickback (rotational reactive force
towards the operator). To prevent kickback,
never use the guide bar nose or perform a
penetrating cut. Always beware of the position
of the guide bar nose.
27. Check the chain tension frequently. When
checking or adjusting the chain tension,
switch o󰀨 the tool and remove the battery
cartridge. If the tension is loose, tighten it.

be performed by Makita Authorized or Factory Service
Centers, always using Makita replacement parts.
Sharpening the saw chain
Sharpen the saw chain when:
• Mealy sawdust is produced when damp wood is
cut;
• Thechainpenetratesthewoodwithdi󰀩culty,even
when heavy pressure is applied;
• The cutting edge is obviously damaged;
• The saw pulls to the left or right in the wood.
(caused by uneven sharpening of the saw chain or
damage to one side only)
Sharpen the saw chain frequently but a little each time.
Twoorthreestrokeswithaleareusuallysu󰀩cientfor
routine resharpening. When the saw chain has been
resharpened several times, have it sharpened in our
authorized service center.
Sharpening criteria:
WARNING: An excessive distance between
the cutting edge and depth gauge increases the
risk of kickback.
►Fig.38: 1. Cutter length 2. Distance between cutting
edge and depth gauge 3. Minimum cutter
length (3 mm)
— Allcutterlengthmustbeequal.Di󰀨erentcutter
lengths prevent the saw chain from running
smoothly and may cause the saw chain to break.
— Do not sharpen the chain when the cutter length
has reached 3 mm or shorter. The chain must be
replaced with new one.
— The chip thickness is determined by the distance
between the depth gauge (round nose) and the
cutting edge.

20 ENGLISH
— The best cutting results are obtained with following
distance between cutting edge and depth gauge.
• Chain blade 90PX : 0.65 mm
• Chain blade 91PX : 0.65 mm
►Fig.39
— The sharpening angle of 30° must be the same on
allcutters.Di󰀨erentcutteranglescausethechain
to run roughly and unevenly, accelerate wear, and
lead to chain breaks.
— Useasuitableroundlesothatthepropersharp-
ening angle is kept against the teeth.
• Chain blade 90PX : 55°
• Chain blade 91PX : 55°
File and le guiding
— Useaspecialroundle(optionalaccessory)for
saw chains to sharpen the chain. Normal round
lesarenotsuitable.
— Diameteroftheroundleforeachsawchainisas
follows:
• Chain blade 90PX : 4.5 mm
• Chain blade 91PX : 4.0 mm
— Theleshouldonlyengagethecutteronthefor-
wardstroke.Lifttheleo󰀨thecutteronthereturn
stroke.
— Sharpentheshortestcutterrst.Thenthelength
of this shortest cutter becomes the standard for all
other cutters on the saw chain.
— Guidetheleasshowninthegure.
►Fig.40: 1. File 2. Saw chain
— Thelecanbeguidedmoreeasilyifaleholder
(optionalaccessory)isemployed.Theleholder
has markings for the correct sharpening angle of
30° (align the markings parallel to the saw chain)
and limits the depth of penetration (to 4/5 of the
lediameter).
