Transport of Product/Handling
-This product is delivered completely mounted, with all guards and safety
elements, controls, engine oil charge and necessary accessories ready to work
-This product is attached to a wooden pallet. While handling, you may use a lift
truck or a crane (suspension in the given lashing points only) – unloading
together with the pallet.

13
-The manufacturer delivers the machine shrink-wrapped. The protective foil
protects the machine against weather effects but in no case against mechanical
damage, fall etc.
-The protective foil is recyclable; dispose it according to valid local regulations.
-While putting the machine aside (e.g. at reloading), we recommend to place it
under a shelter to protect the foil against direct sunshine.

-While lifting by means of a crane (tackle), use only the given lashing points to
suspend the load (marked with chain symbols).
-CAUTION! Never suspend the load on instable (tiltable) parts.
-Any other way of lifting is not allowed.
-The grip should not be in collision with clamps.

-For crane handling, use a crane (tackle) with its minimum carrying capacity of
200 kg.
Unloading from transport pallet
Unloading from transport palletUnloading from transport pallet
Unloading from transport pallet
After delivery unload the machine from the transport pallet as follows:
-Cut the binding bands carefully. Be careful, the band is tightened up and after
cutting its both ends may shot out. While cutting the band use protective
gloves.
-Lift up the machine in order to remove the transport pallet and put it on the
ground.
-It is also possible to ride down directly from the pallet: first remove the scotch
blocks and use them as ramps against the wheels.
-Set the grip in its working position and lock it with a relevant locking bolt.
-Put the blocks in front of the pallet in the wheel spacing, in direction of the
supposed travel.
-Lift up the supporting leg and release the brake.
-Before pushing the machine off the pallet, make sure if the space for the
machine is free enough (presence of persons, animals).
-WARNING! Having pushed the machine, it will "move out" faster because of
its weight (about 145 kg).
Precautions in Design
Precautions in Design Precautions in Design
Precautions in Design
This machine is provided with safety guards protecting against any contact with
rotating parts (hit and pull-in hazard) and against hot parts (exhaust manifold). The

15
guards are fixed, bolted down and solid, only the guard over the exhaust manifold
is perforated.
At standstill the cutting head is covered with a pipe framing protecting the cutting
head and its blades against hitting.
Under the grip there is the "dead-man lever" installed which has to be pushed down
while working.
CAUTION! This machine cannot be started if this control lever is not pushed
down.
Caution !!! Having released the dead-man lever, the cutting head is
freely running out . Any further handling/motion is allowed only after dead
stopping of the cutting head. Any braking of the head, while running out, is
strictly forbidden.
Before starting and while
running, the dead-man
lever must be always held
down
on the green grip, see fig.
It is strictly forbidden to tie up the dead-man lever and to disable it
anyhow
– it serves for your safety.

Operation
-Before the first putting into operation check up the machine for contingent
damages and completeness after transport and storage.
-Check up wrapping for contingent oily spots.
-Check up the engine oil level with a dipstick and top up if necessary. The
engine oil level should be kept between both marks (MIN and MAX).
-Check up optimal slack of belts. It should be 10 - 15 mm.
-For replacement use always original spare parts only.
-Check up tightening of bolted joints, especially rotating parts and
completeness of other subgroups.

19
-Check up the cutting blades for wear and completeness. If one of them
I s damaged, change both opposite blades immediately.
-If different abrasion occurs, change both opposite blades on account of balance
of the cutting head – unwanted vibrations may damage the machine.
-Fill the given fuel into the tank, min. volume of 2 litres. The tank has its max.
capacity of 6,1/7,3 litres.
-The fuel to be used is unleaded petrol, ON 95.

the attendant's height in order to make the operation of this machine more
comfortable.
-Having turned off the machine, avoid any contact of the cutting head while
resting on the ground or on any hard objects. When putting the machine aside
use always its supporting leg.
-Keep all unauthorised persons or animals beyond the handling range.
Set the cutter arm onto the stump, release the brake and the swivel
base lock and start cutting in a swinging way to take individual stump layers
continuously off.
-Any servicing of the cutter can be carried out by authorised persons only. If
necessary, contact an authorised service.
