Safety Instructions
Any power tool can be dangerous.
Please follow these simple procedures.
They are for your protection.
Special safety measures are necessary at working with the chain saw.
Working with it is a lot faster than with an axe or hand saw and because you
are working with a high speed chain.
The clothing has to be appropriate and shall not hinder.
Wear tight clothes with cut protection inlay - insert-combined suit, no working
suit!
There should be no clothing, no scarf, no tie, no jewels – that can possibly get
into wood or undergrowth. Take care of long hair (hair-net)!
Wear tight and non-slip gloves -made of chromium leather, preferably!
Wear safety boots with maximal grip and steel cap!
Use a hard hat if parts could fall down!
Wear ear protection!
Wear safety goggles!
Wear personal noise protection – like e. g. ear flaps!
Consider sufficient cooling and lubrication of chain and bar.
Observe the accident prevention regulations of the employer’s liability insurance association.
Who is working with such a saw for the first time, should be instructed by the seller how to
handle it or should take part at a special course of instruction.
Minors are not allowed to work with such a saw except for juveniles over the age of 16, who get
trained under supervision.
Keep children, animals and viewers away!
The user is reported for accidents or risks, which can be against other people or their property!
Do only give the motor saw to people who know the model and its handling and do always give
the operating instructions to them.

Who is working with a motor saw has to be fit
- awake, healthy and in good shape
- has to lodge working breaks in good time
-is not allowed to work with such a saw while you are under the influence of
-medication, alcohol, or other drugs, because that can affect the reaction.
With hear protecting that has been put on, you have to be attentive and careful, because the
recognizing of dangerous sounds (screaming, signal sounds, etc.) is disturbed.
Do not work alone!
You have to keep a position where other people can hear you, if an accident happens and you
start screaming.
Do only use attachments, which have been delivered by SPITZNAS or have been explicitly
released for the attaching!
Other attachments are not allowed to be used, because they could lead to bigger dangers.
SPITZNAS takes out any liability for person- and property damage, in which use of not
approved attachments has occurred.
Before starting the saw
Check if the saw is in safe condition.
Observe the corresponding chapter in the operating manual:
The guide (bar) has to be fixed properly
Chain has to be tensioned properly
Valve lever and valve lever latch have to be fingertip easy.
Valve lever has to rebound into the neutral position by itself.
Do not make changes concerning the operating and safety equipment!
Keep the handles clean and dry from resin – for the safe guiding of the motor saw!
Correct operation pressure (see technical specifications)
Chain-break must be in proper condition
When working in explosive areas, pay attention to proper lubricating and cooling of the
chain and the bar.
The chain saw should only be used in totally safe condition (Danger of accident).
Starting the chain saw
The chain saw is only used by one person. Do not tolerate other people in the working area!
Do always hold the saw tight in both of your hands for the proper guiding.
The right hand is holding the rear handle (even left-hander) - pipe handle and handle should be hold
tight with the thumb.

Make sure that you are standing very solidly.
Put the saw under full power into the cut and place the spiked strip fixed- only then start to cut.
Defend dangers in general
When you have put on the ear protection, you need to be very attentive and careful because
you cannot recognize dangers soon enough (sounds like screams, signals etc.)
If there is a danger, immediately switch off the motor.
Do not put parts of the body into the enlarged sawing range of the chain.
Pull the saw out of wood only if the chain is still working.
Never work without a stop. The saw can possibly pull the worker to the front.
Work attentively and quietly,
- only with good light and clear sight
- do not get others in danger,
- attentive working is important.
Use a guide which is as short as possible
Be careful at slickness,
when wet, snow, ice, on slopes or uneven off-road,
on fresh peeled wood (bark).
When you work in higher altitude, a lift working platform should always be used! Never
work on a ladder!
Never work in unsolid places!
Never work above shoulder level!
Never work with only one hand!
Chain saw shall only be used for cutting, not for lifting up or
scooping away cut-off pieces.
Only wood or wooden things shall be cut.
Do not let foreign substances touch the saw. Stones, nails, etc. can sling away and
can damage the chain and the chain saw can possibly bound up!

At the slope do always stand at the top or at the side of the log or of the laying tree.
Take care of the down-rolling logs!
Danger of stumbling!
You can fall over roots, stumps of trees or ditches:
Be careful when you cut spilling wood. There is a danger of injuring with spilling pieces of
wood.
Danger because of kickback! Kickback can lead to deadly cutting injury!
If a kickback happens, the saw suddenly can sling towards the user, e.g.
if the chain hits unintentionally wood or a hard object in the area around the upper
quarter of the bar nose.
If the chain on the bar nose gets stuck in the cut.
Reducing danger of kickback
Hold the saw tightly with both hands and safe grip
Do only cut with full power
Do always watch the bar nose
Do not cut with the bar nose
Do not bend forward so far
Do not cut above shoulder level
Do only put the bar very carefully in the cut
Do only "plunge", if you are familiar with that working
procedure

Pay attention to the position of the trunk and to the forces which close the cutting slot and
can jam the chain
Do only work with an appropriately sharpened and tensioned chain. The clearance of the depth
limiter should not be too large.
Decreasing the danger of accidents
Quick-stop chain-brake:
With this the danger of injuring can be reduced in certain situations, but the kickback itself
cannot be avoided. When releasing the chain-brake the chain comes to standstill in a split
second as described in paragraph „Chain-break“.
Cutting set:
Kickback arms, properly sharpened chains as well as a bar with a little bar head
decrease danger of kickback.
It is a lot safer to avoid kickback with clever and proper work.
Avoid drawing in and rebound!
A = To draw in
If at the cutting with the subside of the bar (forehand-cut), the chain jams or touches a tough
object in the wood, the chain saw can be abruptly pulled towards to the trunk.
The spiked strip shall always be fixed safely!

WARNING
Lacking stability
Squeezing of hands and feet!
 Prevent machine/ parts from tilting, falling over or falling down during
re-assembly/ disassembly
NOTICE
Spitznas service is at your disposal for all maintenance, upkeep and assembly
work.
Service life and performance of the chain saw are determined by
a) Degree of air purity
b) Lubrication and maintenance
To a) Blow the air hose clear before connecting it to the saw. Install dirt and water separators
upstream of the saw, if it is not possible to prevent the formation of rust and water
condensation in the air distribution lines.
To b) The motor is lubricated by the lubricator installed in the handle. Fill the lubricator with resin-
and acid-free SAE 5W – SAE 10W lubricating oil. Thick flowing oil will clog the vanes and
affect the start-up and performance of the motor. Only proper maintenance can ensure
constant performance, reduction in wear and thus, a decrease in operating costs and an
increase in service life.
We therefore highly recommend installing service units upstream of the machine.
Observe the comments in the information sheet “Maintenance of Pneumatic Tools”!
Closed greased ball bearings must not be flushed.
After use, clean the saw and rinse it with light oil or provide alternate corrosion protection.
Regularly check and clean the air inlet screen.
In winter, or when using very moist air, an antifreeze lubricant, such as BP Energol AX 10,
Kilfrost or Kompranol should be used.
Replace wear parts – in particular the vanes – when necessary.
Vanes are considered worn, if their width is less than 16 mm.
Lubricating the saw chain is done automatically by the second lubricating system.
The oil tank situated in the motor housing, size approx. 250 ccm, has to be filled with chain saw oil
before starting. It contains oil for approx. 2 working hours. You can check, if oil is conveyed to the
chain, by holding running saw with the bar pointing downwards and, if adjustment is correct, an oil
trace will be clearly observed on a light coloured floor or paper.
Use machine oil with adhesive additive of a viscosity of 49-55 c ST (6.5 – 7.5 E) at 50°C (122 F).
