SAFETY INSTRUCTIONS
8
Measuring hydraulic pressures and their adjustments shall only be performed by a service
man familiar with hydraulics, and only in a meticulous and careful way.
During the connecting of pressure hoses, adjustment of valves and other repairs, the
engine has to be shut off and the jaw crab depressurized, as the service personnel will be
in the immediate vicinity of the movements of the jaw crab.
At the time of measuring, the person performing the pressure metering and any possible
assistants shall be out of range of the jaw crabs movements.
Raising the pressure levels create an over-pressure situation which can break the jaw
crab. Danger of accident!
Keep the hydraulic hoses of the energy timber jaw crab in impeccable condition. Exchange
broken ones for new. A high-pressure squirt of oil can be ejected from a defective hose or
coupling, should it hit the skin it can penetrate it and cause a serious infection. Should this
happen, immediately seek medical attention.
When finishing work or stopping the motor, always lower the energy timber jaw crab unto
the ground or a similar solid base.
Standing underneath the energy timber jaw crab is always strictly forbidden.
When working with, or servicing, the machine, avoid letting your skin come into contact
with oil or grease. Oil and grease may contain additives, which can be harmful if
repeatedly coming into contact with the skin. When handling these substances, adhere to
advice and regulations issued by the manufacturer and the authorities.
Beware of hot oil!
When handling oils and greases, use appropriate protective clothing, barrier cream for
your skin, or appropriate gloves. Also use protective goggles.
Do not use lubricating oil or grease when cleaning your hands. Possible metal slivers in
the lubricating matter may damage the skin.
Should oil or grease cause changes to the skin, contact your doctor immediately.
Waste oil or oily hoses from service or repairs are to be deposited and treated as being
harmful to the environment.

reduction valve, suitable for the energy timber jaw crab. Check the correct type-specific
pressure from the technical information covering the energy timber jaw crab.

OPERATION
10
4 OPERATION
4.1 SECURITY INSTRUCTIONS
Familiarize yourself thoroughly with the operating- and safety
instructions before beginning to operate the energy timber jaw crab,
and follow them throughout the whole operation.
Make sure that the combination is firm on soft ground and slopes, and engage the parking
brake during felling and handling.
Before starting the motor, make sure that nobody is within the danger zone...
Test all energy timber jaw crab functions at the start of the working period...
Make sure that you can observe the whole working area without hindrance.
Make sure that there is nothing underneath or near the tree being felled, which could be
damaged by the falling tree (for example, people, animals, buildings, Phone- or electrical
lines).
Should there be people within or near the work area, lower the energy timber jaw crap to
the ground, shut down the engine and go and direct the people out of the area before you
continue working.
DANGER AREA 25m.
Persons who have not received training are not allowed to operate the machine. As the
operator, you are responsible that the machine does not cause damage to others.
4.2 HANDLING OF TIMBER
4.2.1 Felling
Open the jaws of the energy timber jaw crab and turn it vertically by simultaneously using
the open jaws function and the jaw turner.
Move the energy timber jaw crab near the tree to be felled. Observe the tree’s falling
direction and angle of growth. DO NOT TRY TO FELL A TREE AGAINST A HEADWIND.
Do not try to fell trees too large: Security risk as well as the risk of breaking the energy
timber jaw crab. The maximum allowed diameter of the tree at the cutting point is 18 cm.
Type of tree and other circumstances (for example, icing of the tree) can limit the diameter
of the tree to be felled to less 18 cm.
Grip the tree with the energy timber jaw crab. Close the jaws, upon which the jaws will
push the cutting edge against the tree.
Do not raise or lower the crane while cutting, there is a risk that the cutting edge could be
twisted.
Tilting the jaw grab by tilting the crane in order to facilitate cutting is prohibited.

OPERATION
11
Often the height of the tree is so great, that the tree will first have to be cut higher up on
the trunk.
When the tree has broken, use the crane to lift it to a suitable place.
Open the jaw and lift it back into felling position.

5.1 SAFETY INSTRUCTION
NOTE! Pre-service measures
The engine of the basic machine has to be turned off. Take care that no parts of the
energy timber jaw crab are subject to pressure. Shut the motor and move the pistons of
the valve about, in order that pressures in the energy timber jaw crab safely are returned
to the tank. Should the valve be electrically controlled, the steering current must be on.
5.2 DAILY SERVICE
Lubricate all of the emery timber jaw crab’s grease nipples once every 10 working hours.
The indicated lubricating interval only applies when the machine is used at normal loading
strains in normal working conditions. Shorten the lubricating intervals if the machine is
under exceptional strain or if the working conditions are adverse (high temperatures, dust,
heavy mud, or equivalent).
Keep an eye on possible oil leaks, hoses, and constructional details, tightness of screws
and nuts, as well as axle locks.
Keep the energy timber jaw crab free of snow, ice and rubbish.

space allotted.

SERVICE
15
5.7.2 Sharpening the cutter
By keeping the cutter sharp and the sharpening correctly shaped, the force needed for
cutting the tree is lessened, and the workload of the machine is lightened.
When sharpening the blades with an angle grinder one must take care not to heat and
soften the material by too rapid grinding. The best way to sharpen the blades is by using a
file. If there is much to be sharpened, one first uses a grinder and a fine, lamina-type
emery wheel. <below is a sharpening picture as guidance.

6 TROUBLESHOOTING INSTRUCTIONS FOR THE
ENERGY TIMBER JAW CRAB
6.1 GENERAL
On part of the materials and components of the KESLA energy timber jaw crab, one has
tried to predict the operational conditions that the energy timber jaw crab will face during
use.
In spite of everything, functional disorders can happen; therefore this troubleshooting
instruction is intended to assist in finding the possible failure.
Grime, which makes its way between the valve rods or into the opening of the choke, can
cause interference in the hydraulic system. The greatest risk of having dirt entering the
system comes in connection with the changing of hoses. When changing hoses, special
care has to be taken.
