Before commencing work
Before commencing work, make yourself familiar with the working environment at the place of
use. The working environment includes: obstacles in the area of work and manoeuvre, the
firmness of the floor, necessary protection at the site relating to public thoroughfares and the
availability of help in the event of accidents.
Check for correct mounting of the tool regularly.
Immediately remove damaged or badly worn tools, as they endanger the operator whilst
rotating.
Always cut with the safety guard ring in position.
Only fit NORTON blades or plates to the machine! The use of other tools can damage the

Handle (1)
Jig welded steel construction including 2 rubber grips. A dead-man handle (2) allows the operator to
work safely and to stop the machine at any moment. The angle of the machine arm can be adjusted
to operate the machine comfortably.
Pitch of the blades (3)
The pitch of the blades is controlled over a hydraulic pump on the handle.

3 Assembly and commissioning
The machine is delivered fully equipped. It is ready for operation after assembly of the tool and
adjustment of the machine arm, and after connection to the appropriate power supply.
3.1 Safety guard ring and handle
To avoid the guard ring to be damaged during the transportation, it is transported disassembled
from the machine. To assemble it, follow these points:
Fit the section of the guard ring with the large welded plate at the front side of the reducer (with
M10 screws and the 17mm wrench).
Fit the two small plates of the guard ring on the right and left side of the handle (with M10
screws and the 17mm wrench).
Fit also the second locking screw of the belt guard (with M8 screws and the 13mm wrench).
Unlock the locking lever of the handle. To adjust the height of the rubber grips to the operator’s
size, move the handle backwards. Fix the handle on the desired position by tightening the locking
lever.
3.2 Tool assembly
Only NORTON blades or plate with a maximum diameter of 865 mm can be used with the MTA36.
Before mounting a new tool into the machine, switch off the machine.
Screw the 2 M8-screws per blade using a 13mm wrench to assemble the blade on the arm. To
10
assemble a plate, place the machine with the blades assembled on the plate, and turn it until the
blades are located in the hooks on the plate.
3.3 Starting the machine
Turn the fuel valve to the ON position. Make
sure the throttle handle is on the intermediate
position.
Move the choke lever to the CLOSED position.
NOTE: do not use the choke if the engine is
warm or the air temperature is high.
Move the throttle control lever slightly to the
left.
Put the engine switch on ON, and make sure
the emergency switch on the board of the
machine is in the correct position.
Pull the starter grip lightly until you feel
resistance, then pull briskly.
CAUTION: Do not allow the starter grip to
snap back against the engine. Return it gently
to prevent damage to the starter.
As the engine warms up, gradually move the
choke lever to the OPEN position.
Position the throttle control lever for the
maximum engine speed.
To stop the engine, move the throttle control lever fully to the right, then turn the engine switch to
