WARNING!
IT IS VERY IMPORTANT THAT YOU READ THIS
MANUAL BEFORE OPERATING YOUR CHAINSAW
CHAINSAWS CAN BE DANGEROUS
Each year many people are injured in chainsaw
accidents. Most of these accidents can be avoided. The
hands, knees, feet and head are most vulnerable to
being cut by the saw chain.
If you use a chainsaw often, there are also other health
risks. The continual noise of the chainsaw can lead to
permanent hearing loss and vibration can cause
permanent damage to the hands.
These hazards mean that chainsaws are potentially one
of the most dangerous pieces of industrial equipment if
not used correctly.
With the use of the correct protective clothing, and
proper work practices, this equipment can be used
safely.
In the next few pages you’ll read valuable information
concerning safe chainsaw operation. There is a checklist
of the safety instructions. Tips on the protective clothing
you should wear, and suggestions for safe work methods
are provided. Please read on!

GENERAL SAFETY PRECAUTIONS
This owner’s manual will tell you the safety features of your
chainsaw and the correct way of operating it.
Check your chainsaw thoroughly before use. Make sure your
bar, chain and sprocket are in top condition and that all safety
devices are working properly.
Regularly service your chainsaw.
Always wear protective clothing. Gloves, safety helmet with
visor or goggles, earmuffs, protective leggings and safety
boots should be worn at all times whilst operating your
chainsaw.
Do not start cutting until you have a clear work area, secure
footing and a planned retreat path from the operating area.
Keep other people and animals well away from the working
area.
Make sure there is a second person within calling distance.
Do not operate a chainsaw that is beyond your ability.
Use the chainsaw only to cut the correct material with the
correct chain.
Do not become distracted. Stop the chainsaw if somebody
starts speaking to you.
If you are tired, rest! Chainsaw operation requires maximum
and constant concentration. Tired operators can have
accidents.
PERSONAL SAFETY EQUIPMENT
Gloves, safety helmet with visor or goggles, earmuffs, protective
leggings and safety boots should be worn at all times whilst
operating your chainsaw to protect you from chain saw injury.

PREVENTING KICKBACK
Kickback is a sudden upward and backward movement of the
saw. It occurs when the tip of the bar nose contacts a log,
branch or nail. It can cause serious injury.
FIGURE 1
TO PREVENT INJURY FROM KICKBACK
Ensure your chain saw is fitted with a chain protector safety bar
and a bumper spike.
Use low kickback chain types and avoid lowering the depth
gauges too much when sharpening.
Hold the chainsaw firmly making sure that the left hand
encircles the top handle with the thumb underneath.
Avoid bringing the upper quadrant of the guide bar into
contact with any foreign object.
Wear correct head protection and safety pants at all times.
Avoid cutting above your shoulder height.
Never hold the chainsaw in one hand.
Always begin at peak (rev’s) power.
TIMBERKING Pneumatic Chainsaw Operating Manual V3 | 20.04.15
5
PREVENTING RAYNAUD’S DISEASE AND OCCUPATIONAL OVERUSE
SYNDROME
The vibration from chainsaws can cause damage to the hands if
used for long periods of time.
Use the chainsaw with ergonomically angled handles. These
greatly reduce uneven and undue pressure on the hands.
Take regular rest breaks from continuous operations.
Wear gloves.
Sharpen your chain regularly. This will ensure smoother cutting
and less vibration.
MAINTAINING YOUR CHAINSAW
A chainsaw is designed to meet various safety requirements. Use
the diagrams to check and understand the safety features, even
if they may be optional extras when you buy it.
Never operate a chainsaw that is damaged, not properly
adjusted or wrongly assembled. Your chainsaw requires regular
maintenance.
IMPORTANT!
If your chainsaw is used underwater, the motor must be flushed
immediately after use with preservatives such as Valvoline Tectyl
930.
BEFORE YOU START WORK, CHECK THAT…
1. The machine is in good condition (no leaks, wear or damage).
2. The throttle trigger and safety throttle lock operate correctly.
3. The chain is lubricated, sharp and tension is correct.
4. The air pressure is correct. Maximum 7 bar – do not exceed!
TIMBERKING Pneumatic Chainsaw Operating Manual V3 | 20.04.15
6
AFTER FINISHING YOUR WORK, OR DAILY…
1. Clean the chainsaw, particularly the sprocket guard.
2. Check the chainsaw thoroughly from top to bottom, see that it
is lubricating properly.
REGULARLY…
1. Sharpen your saw chain.
2. Check the guide bar for burring.
3. Check the sprocket for wear. It can clog up with oil and dirt
and may malfunction.
4. Have your chainsaw serviced regularly.
PREVENTING NOISE INDUCED HEARING LOSS
Most chainsaws emit noise levels that can cause permanent
damage to your hearing if used for long periods at a time.
Always use safety standards approved earmuffs or plugs.
Ensure your chainsaw is tuned to manufacturers specifications.
PREVENTING FIRES
1. Don’t smoke while operating the chainsaw.
2. Keep a fire extinguisher, spray pump and shovel nearby.
TIMBERKING Pneumatic Chainsaw Operating Manual V3 | 20.04.15

TRAINING AND SUPERVISION
Chainsaw operators should be properly trained. Training may be
on-the-job or through a recognised training course. Training
should include instructions on:
Safe working techniques.
Operating conditions, including unusual or dangerous
conditions.
Basic information about the chainsaw and its controls,
attachments and components, design capacity, stability and
limitations.
Correct stopping and starting techniques.
Cleaning and servicing.
Being alert for the possibility of kickback.
Chain sharpening techniques.
Less experienced operators should be carefully supervised.
Certain operations are extremely dangerous and should only be
undertaken by professionals. These include the removal of
branches from standing trees, the removal of trees hung up in
wires, cutting trees thicker than the guide bar length, and working
in windblown and foul weather areas.
TIMBERKING Pneumatic Chainsaw Operating Manual V3 | 20.04.15

A REVIEW OF SAFETY PROCEDURES
Operator should wear dress of close fitting style, safety boots
and leather gloves.
When carrying the chainsaw about, the chain should be fitted
with a chain guard.
Chainsaws should never be run without oil.
Always hold the saw with both hands and keep a firm stance
when working with the chainsaw.
No other person should stand within the working radius of the
saw.
Before you start cutting, press the spike bar against the
material being cut.
When cutting splintered wood, take precaution. Large splinters
can fly towards the operator.
Only use the underside of the bar when cutting at shoulder
height. T
he pressure hose should be closed when the chainsaw is set
aside even for a short while or when the chain tension is tested
or adjusted.
The operator should always work calmly and cautiously and
should also avoid any danger to themselves or other persons.
TIMBERKING Pneumatic Chainsaw Operating Manual V3 | 20.04.15

ASSEMBLING THE GUIDE BAR AND CHAIN
Direction of the chain travel (L), the cutting edges of the chipper
chain on the top edge of the guide bar must face in the direction
of the guide bar nose. Put the pivot of the square nut for chain
tensioning into the tap-hole in the guide bar. Assemble the
sprocket guard and screw the nut finger tight.
FIGURE 2
TIMBERKING Pneumatic Chainsaw Operating Manual V3 | 20.04.15
10
TIGHTENING THE CHAIN
Turn the tensioning screw clockwise. The nose of the guide bar
should be lifted slightly. The chain should not sag but should be
easily moved by hand (wear gloves) alongside the guide bar.
Tighten sprocket guard nut. A newly fitted chain should be
allowed to rotate for 5 minutes with good lubrication and then
re-tighten the chain.

FILLING OF SAW CHAIN OIL
Figure 4B – PLEASE: Never use old oil!
Tank cap CHAIN OIL (A): Special non-drip chain oil, otherwise use
regular grade SAE 30 engine oil. Tank capacity is 0.49 Litres.
FIGURE 4B
TIMBERKING Pneumatic Chainsaw Operating Manual V3 | 20.04.15

CONNECTION OF COMPRESSED AIR
Inside thread in rear handle ¾” B.S.P. For reasons of safety it
should be easy to switch off the compressed air within reach of
the working place. Blow out pressure hose before connecting.
System pressure 85 to 100 p.s.i (6 to 7 bar).
MOUNTING A NEW CHAIN
1. Loosen mounting bolt.
FIGURE 5
2. Tighten chain tension adjustment screw until the coupling links
touch the bar. Lift bar nose slightly whilst adjusting tension.
FIGURE 6
TIMBERKING Pneumatic Chainsaw Operating Manual V3 | 20.04.15
13
3. Pull chain around by hand.
FIGURE 7
4. Lift bar and tighten mounting bolt.
FIGURE 8
AFTER MOUNTING A NEW CHAIN
1. Allow chainsaw to run for a short period of time at low speed
while applying a liberal amount of oil to the chain.
2. Turn off motor and re-adjust chain tension. Re-start saw and
make a few light cuts. Re-adjust chain again if necessary. It is
important to monitor chain tension during the first half-hour of
operation.

OPERATING INSTRUCTIONS FOR PNEUMATIC CHAIN SAW
CHAIN CARE (Figure 9)
The illustrations shown in figure 9 clearly show the difference. The
second chain received excellent care. It still cuts, even though
the cutting teeth have been filed almost completely back. The
top chain is no longer serviceable, even though it was hardly
used.
FIGURE 9
TIMBERKING Pneumatic Chainsaw Operating Manual V3 | 20.04.15
15
Observe the following rules to obtain the best performance from
your chain:
1. Inspect the bar before mounting a new chain. Never run a
new chain on a worn bar.
2. Make sure the chain tension is correct. Do not run your
chainsaw with a chain that is too loose.
3. Sharpen your chain correctly. Follow the sharpening
instructions shown in figures 10 through to 12.
4. Always use plenty of oil when cutting. Oil is cheaper than a
new chain.
5. Keep the oil hole in the bar and the bar mount clean. Clean
these two points at least once a day.
6. When cutting frozen wood, mix approximately 25% diesel fuel
or kerosene with the chain oil.
TIMBERKING Pneumatic Chainsaw Operating Manual V3 | 20.04.15
16
CHAIN SHARPENING
(Figure 10)
Use chainsaw file with 5.5mm (7/32”) diameter for 0.404” pitch
chain. It is better to file at frequent intervals. File horizontally and
in the correct top plate angle (35 degrees), filing stroke should go
always from inside to outside. All cutters have to be precisely the
same length and height. Use chain gauge for inspection.

LOWERING THE DEPTH LIMITER
1. When sharpening your chain with a file holder, the clearance
depth limiter must be checked and adjusted if necessary after
sharpening.
2. Check the clearance of the depth limiter 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 a flat file (Figure 11A).
4. Round off front edge of depth limiter. Its original shape must be
preserved (Figure 11B).
FIGURE 11
TIMBERKING Pneumatic Chainsaw Operating Manual V3 | 20.04.15

NOTE: Always completely file away any damaged areas on side
plate and top of tooth.

FIGURE 12
CHAIN BAR – IMPORTANT!
Bars are designed only for the purpose of guiding the chain, and
should never be used as crowbars. Turning, twisting and using the
bar as a lever, will shorten its service life and void the warranty.
The bar of your chainsaw needs as much care as the chain. The
running surfaces must be flat and smooth and the groove must
not be expanded. Inspect the groove as shown (Figure 13).
TIMBERKING Pneumatic Chainsaw Operating Manual V3 | 20.04.15

FIGURE 13
REGULATING THE CHAIN BAR OIL VALVE
Saw chain oil is supplied to the guide bar from the pressurized
tank by means of an adjustable needle valve.
Loosen lock nut ‘A’ – adjust knurled screw ‘B’ to obtain desired
flow.
Clockwise for minimum flow – anti-clockwise for maximum flow.
Re-tighten ‘A’.
Use Special Chain Oil!
FIGURE 14
Lubricate the motor with an ‘In Line’ oil mist lubricator – Adjust
screw ‘A’ to obtain desired mist – a slight film of oil should be felt
at exhaust port – (Silencer removed), (Clockwise for minimum
flow – anti-clockwise for maximum flow). Setting of 1 – 2 is general
with No. 10 oil. Use light, non-resinous machine oil e.g. Shell, Telsus
C10 or equivalent.
It is desirable to keep lubricator within 6 metres of chain saw.
TIMBERKING Pneumatic Chainsaw Operating Manual V3 | 20.04.15
26
ASSEMBLY
Assembly is performed essentially the same as disassembly, but in
reverse order. Make sure motor clearance is correct. When the
bearing is tight, the longitudinal clearance between the flat rear
surface of the rotor and the rear gasket should be approximately
0.04mm. Correct by grinding spacer ring if necessary.
FIGURE 15
TIMBERKING Pneumatic Chainsaw Operating Manual V3 | 20.04.15
27
HOW TO USE THE SAW STARTING AND STOPPING THE MOTOR
Only after oil tank is filled! Depress safety lever ‘C’, Press the
regulating lever ‘D’ in the rear handle.
Attention! Chain starts immediately. Letting go of the regulating
lever reduces the speed and finally stops the motor and chain. At
working breaks the air pressure should be switched of with a
nearby stopcock.
FIGURE 16
Check lubrication of the chain. At the cutting point the timber
has to be clean from sand, nails and the like. Do not allow the
chain to touch the ground. Underwater cutting has to be done
always with rotating motor so that no water may penetrate to the
motor.
TIMBERKING Pneumatic Chainsaw Operating Manual V3 | 20.04.15

BUCKING: Position the spike bar, press the regulating lever and
make the cut with running chain by lifting up rear handle (1)
Figure 17. Use the front handle for guiding only.
FIGURE 17
RE-POSITIONING (2): Apply vertical pressure to the front handle.
Continue cutting with regulating lever fully pressed in.
PLUNGE-CUTTING (3): Position the chainsaw with the wood, swing
back the nose and make the plunge-cut. Pull out spike bar and
shift to a lower position.
LIMBING: Make a shallow cut on the pressure side (4). Cut through
from the tension side (5).

INSTRUCTIONS FOR SAFE OPERATION
Please follow these safety rules for your own protection.
1. Plan ahead. Lay your work out before you start and always
work at a deliberate pace. Fatigue leads to carelessness and
accidents.
2. Keep your work area clean and un-cluttered.
3. Wear the proper clothing. Clothing which is too tight or too
loose is not suitable. It can restrict your movements or be
caught up in the saw.
4. Protect your head (eyes and ears), hands and feet.
5. Grab the saw securely with both hands during use! Make sure
the material you are cutting will not roll or slip. Make sure your
feet are firmly planted and your body is well balanced. Always
be alert to possible kickback.
6. Always hold the saw to the side of your body.
7. Never carry the saw with the motor running, and always carry
the saw so that the bar points backwards. A chain guard is
mandatory!
8. Never cut in an awkward position. Never cut above shoulder
level. When cutting logs, always cut from the top tier down. Be
alert for stressed pieces of wood, which could spring upward
when cut.

GENERAL MAINTENANCE OF PNEUMATIC TOOLS
Only proper maintenance can ensure constant performance,
reduction in wear and thus, a decrease in operating costs and an
increase in service life.
Our pneumatic tools are equipped for an operating pressure of 6
bar. A regulator setting for an operator setting of 4 bar is possible
as well as expedient for grinding machines with a built in
regulator, so as to take full advantage of the speed prescribed
for the corresponding grinding wheels.
Pneumatic tools should not run empty because this results in heat
and higher wear. The compressed air should be clean and dry.
This is guaranteed by a proper pneumatic system. Blow through
the pneumatic hose before connecting it.
For the economical use of pneumatic tools, the prescribed air
quantities are necessary; i.e. the line, armatures and hoses must
have the required cross sections so that the flow pressure remains
constant.
Proper lubrication is a must; for this reason, our pneumatic tools
have built-in oilers, which are located between the inlet valve
and the motor, and which function in any position. In smaller and
lighter hand tools these oilers must often be left out, because the
machines would then be too heavy and not easy to manage. In
such cases, lubrication must be carried out by service units or by
manual hose oilers. We recommend service units for permanently
installed work places. However where longer hose lines are
necessary, line oilers built into hose lines are more effective. The
distance between the tool and the oiler should not be more than
5 metres.
Lubricating oils to be used:
Generally SAE 5W to SAE10
Continued over page…
TIMBERKING Pneumatic Chainsaw Operating Manual V3 | 20.04.15
31
For damp compressed air, oils are to be used that take up water
(without losing the lubricating effect) and which contain anticorrosive additives. At lower temperatures (especially for work
outside) it may be necessary to use an anti-freeze lubricant e.g.
Kilfrost, BP Energol AX 10 or Kompronal N 74).
For saw chain lubrication:
Use machine oil with adhesive additive,
Viscosity c ST 49 – 55’ (6.5 – 7.5E)/50C
