FOR YOUR SAFETY
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.
Read carefully the whole operating instructions before you start work.
Not observing the safety instructions can be life-menacing.
Observe the accident prevention regulations of the employers‘ 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 juvenils over the age of 16, who
get trained under a supervison.
Keep children, animals and viewers away!
The user is reported for accidents or risks, that 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
them the operating instructions.
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
-you are not allowed to work with such a saw while you are under the influence of
-medication, alcohol, or other drugs, because that can effect 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.

FOR YOUR SAFETY
Do wear provisioning clothing and outwear!
The clothing has to be purposing and shall not hinder.
Wear tight clothes with insert-combined suit, no working suit!
There should be no clothing, no scarf, no tie, no jeweils – that can possibly get into wood or
undergrowth. Take care of long hair (hair-net)!
Wear safety boots with maximal grip and steel cap!
Use a hard hat if parts could fall down!
Do also use goggles!
Use „personal“ hear protection! Like ear-flaps.
Wear tight and non-slip gloves!
Made of chromium leather
Transporting the motor saw
Only if the air supply is separated.
Always attach chain guard – even for transport over a short distance.
Carry the saw only at the pipe handle
Guide (bar) should face to the back!
Transporting in vehicles:
Protect the saw so that it cannot fall to the side and get damaged. If the motor saw is not in use
it should be put to the side so that there is no risk for anybody.

FOR YOUR SAFETY
Do always hold the saw tight in both of your hands for the right guiding.
The right hand is holding the back 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 claw-type stop fixed - only than
start to cut
Defend dangers in general
When you have put on the hear protecting 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 a leg or an arm 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 and only with good light and clear sight.
Do not get others in danger. Attentive working is important.

Pneumatic Chain Saw 5 1020/5 1021/5 1022/5 1023
FOR YOUR SAFETY
Use a guide which is as short as possible:
Chain, guide and sprocket have to fit to each other and also to the motor saw!
Be careful slippery, when wet, slipperiness, snow, ice on slopes or uneven offroad, 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 in unsolid places -
Never above shoulder level -
Never with only one hand!
Motor 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 can sling away and can damage the
chain and the motor saw can possibly bound up!
At the slope do always stand at the top or the right next to the log or to 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.

FOR YOUR SAFETY
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 sure 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 jum the chain
Do only work with a right sharpened and tensioned chain. The clearance of the depth limiter
should not be too large.

FOR YOUR SAFETY
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 can
not be avoided. When releasing the chain-break the chain comes to standstill in a split second
as described in paragraph „Chain-break“ in the operating manual.
Cutting set:
Kickback arms, right sharpened chains as well as a bar with a little barhead decrease danger of
kickback.
It is a lot safer to decrease kickback with clever and right work.
Avoid drawing in and rebound!
A = To draw in
If at the cutting with the subside of the bar (forehand-cut) the chain jums or touches a tough
object in the wood, the motor saw can be abruptly pulled towards to the trunk.
The claw-type stop shall always be fixed safely!
B = Rebound
The motor saw can be pushed back towards the operator, if during cutting with the upper side of
the bar (backhand-cut) the chain touches a tough object in the wood.

MAINTENANCE AND REPAIRS
Maintain the saw regularly. Make only maintenance and repairs that has been described in the
Operating Manual.
Let other work be done by SPITZNAS-after-sales service. Only original SPITZNAS spare parts
should be used.
Do not change anything at the motor saw. The safety could be endangered.

Pay attention to sharpening instructions
for right handling of chain and bar. Keep chain in a perfect shape, right sharpened and
tensioned and lubricated.
Replace chain, guide and sprocket in due time.
Keep motor and chain lubricating oil only in labelled containers according to regulations.
ATTENTION!
If trouble of function of the chain-break occurs shut down the motor saw immediately – danger
of injury!
Look for SPITZNAS-after sales service!
Do not use the motor saw until this problem is not solved (Look chapter „Chain-brake“).
Assembling of bar and chain
Pitch of the chain has to be adjusted to spacing of the sprocket and the bar and thickness of
drive link has to be adjusted to the width of the groove of the bar.
Turn-off nuts and remove cover

Pneumatic Chain Saw 5 1020/5 1021/5 1022/5 1023
MAINTENANCE AND REPAIRS
Adjust tension of chain
during operation:
Stop motor and disconnect it from air supply. Only then loosen the nuts (1)!
Lift bar nose and screw clamp nut (1) with a screwdriver to the right until the chain lies at
the underside of the bar. Go on lifting up the bar and tighten the nuts (1) very strong.
Check chain tension
Stop the motor.
Put on protecting gloves!
The chain has to lie at the underside of the bar and it has to pulled with loosened chain-
brake by hand.
If necessary, adjust tension.
A new chain has to be adjusted oftener than a chain which is already for a longer period
in use.
Check chain tension more often – segment „During the operation“!

Pneumatic Chain Saw 5 1020/5 1021/5 1022/5 1023
MAINTENANCE AND REPAIRS
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 servic life.
We therefore highly recommend to install service units upstream of the machine.
Obsere the comments in the information sheet
„MAINTENANCE OF PNEUMATIC TOOLS“
Enclosed 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 intifreeze 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 of the chain works through the second lubricating system with automatic line oil
pump. The oil tank (250 ccm) is located in the motor housing and has to be filled with chain saw
oil before starting. It contains oil for approx. twoe working hours. Check transparent oil line, if oil
is conveyed to the chain or hold 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). Replace valves of the oil pump, if they are no more leakproof. Before assembling the
valve should be dipped into oil. Pay attention to the right sequence of the valves (ball and
feather should lay next to both valves at the left).
Filling in chain lubricating oil
- Clean the tank screw-cap and the area around, so that the tank cannot get dirty.
- Fill in chain lubricating oil.

Pneumatic Chain Saw 5 1020/5 1021/5 1022/5 1023
MAINTENANCE AND REPAIRS
If the flow in the oil tank does not change lubricating oil delivery can be interrupted.
Check chain lubrication. Clean the oil passages. Possibly look for the SPITZNAS after-sales
service.
Checking the chain lubrication
The chain always has to sling off a little oil.
- Never work without chain lubrication! If the chain is working dryly the cutting set can be
destroyed in short time. Before starting the work always check chain lubrication and the oil level
in the tank.
- Every new chain needs a run-in period time of 2 to 3 minutes.
After running in check chain tension and adjust it if necessary. Segment „Checking chain
tension“!

Blocking the chain with the chain-brake
- when emergency
Hand guard to the bar nose - with the left hand - or automatically - by the kickback:
the chain get blocked and stops
Releasing the chain-brake
- Pull the hand guard to the pipe handle.
Tip: Before opening the handle valve (except for the function control) and before cutting the
chain-brake has to be released.
The chain-brake works only, if no change will be made on the hand guard.
Controlling of function of chain-brake
Every time before starting work: block the chain (hand guard against nose of the bar and open
the valve of the handle for a short time (max. 3 sec.) The chain should not run also. The hand
guard has to be clean and light moveable.

MAINTENANCE AND REPAIRS
Maintenance of chain-brake
The chain-brake is subjected to normal wear. For serving a good performance, it has to be
maintained by well trained personnel (e.g. after-sale-service) at regular intervals:
Professional fulltime work every three months
Half-professional (Agriculture & Construction) twice a year
Hobby and free-time user once a year
Keeping the bar proper
Turn over the bar after every sharpening of the chain or replacing the chain to avoid wear
out on one side only especially at the return steering and the underside.
Clean regularly
1 = Oil inlet hole
2 = Oil outlet port
3 = Bar groove
During the first period of operation
Always pay attention to: Opening of valve only with released chain-brake. Opening of valve at
blocked chain-brake (chain is stalled) causes in a short time to damages on the chain drive
(chain-brake).
During the operation
Check tension of chain more often!
A new chain has to be adjusted more often than one that is in use for longer!

Pneumatic Chain Saw 5 1020/5 1021/5 1022/5 1023
MAINTENANCE AND REPAIRS
In cold state:
The chain must lean against the bottom side of the bar but it has to be still pulled around the bar
by hand. If necessary, adjust tension of the chain again. Paragraph „“Tensioning the chain“!
With operating temperature:
The chain stretches and slacks. The drive links at the bottom side of the bar shall not come out
of the groove. Otherwise the chain can spring out. Adjust tension of the chain, paragraph
„Tensioning the chain“!
After work it is important to relieve tension! During cooling the chain shrinks. A chain which is
not relieved from tension can possibly damage the rotor shaft and the bearing.
After operation
- Relieve tension of chain, if it was tensiond during work at operation temperature.
Chain shrinks during cooling. A chain which is not relieved from tension can possibly damage
the bearings.

MAINTENANCE AND REPAIRS
Sharpening the Chain
Lowering the depth limiter
1. When sharpening your chain with a file holder, the clearance of the depth limiter must be
checked and adjusted if necessary after sharpening.
2. Check the clearance of the depth limit at least after every third sharpening, and after every
sharpening when cutting frozen wood.
3. Place depth limiter gauge on cutting tooth. If depth limiter is too high, file off protruding part
with as flat file (Fig. 1)
4. Round off front edge of depth limiter. Its original shape must be preserved (Fig. 2).
General Filing Instructions
1. Place file holder on top of tooth and depth limiter.
2. First file all cutting teeth 3. Keep marks on file

Chain Repair
Shortening and lengthening the chain
(Chain added between two left-hand cutting teeth)
(Two coupling links and one drive link between cutting teeth)
Most chain saws are assembled with one coupling links between a right-hand and a left-hand
cutting tooth, however there are also chains which are assembled differently due to their length
(number of drive links). If a chain must be shortened or lengthened, it is best to do so at this
point. However do not insert more than two coupling links between two cutting teeth.
