5. ASSEMBLY
Before installation and commissioning, you must ensure that the brushcutter is correctly
assembled accordingto the assembly plan and follow the instructions in this user manual.
Only then you can proceed to actual commissioning.

EN
8
Coupling the transmission to the engine unit (for models that do not have a
coupled transmission)
Connect the transmission to the engine unit using the screws and washers provided.
Fitting the handles
Loosen the screws located on the clamp, by unthreading, until it is free from the thread,
then fix the handles in the working position.

EN
9
Mounting the protective shield
Fit the protective shield to the fixing points and firmly tighten the locking screw.
This has the role of protecting the user from hard bodies that can bounce during use as
well as as the role of load limiter.
Careful! Do not use the brushcutter without this protection shield.
Transmission coupling

EN
10
For modular transmissions that come in two segments, they must be joined together
using the fixing clamp and lock nut.
Assembly - disassembly of the blade and trimmer head
To proceed properly you will need to have the following necessary tools at hand: the hex
key with blocker and the wrench in the brushcutter equipment.
The assembly-disassembly order is shown in fig. 7
Use the hex key with blocker supplied with the brushcutter and position it in the locking
hole of the reducer head and in the locking hole of the spacer in fig. 7 poz. 5.
Use the wrench supplied with the bruhcutter, secure the lock nut and turn
counterclockwise to tighten, or clockwise to loosen.
The 3-teeth blade (item 4 Fig. 7) can be installed on any side with double cutting edge.

EN
11
Fig. 7
Check that the whole assembly is correctly installed and that the blade is firmly tightened
without axial or transverse play.
When installing the trimmer head, items 1, 2, 3 and 4 in Fig. 7 are not used. The hex key
with blocker (pos. 5, Fig. 7) is used, which helps locking the shaft of the reducer head,
and the trimmer head is then threaded, counterclockwise, by hand, with the help of the
wrench and tighten strongly.
If you fail to do so, you should immediately visit your nearest Ruris authorized service
point to have this problem solved.
Harness assembly
To install the harness you will need to position it on the shoulders and then secure it.
The harness can be easily attached to the user's body by means of fast-type adjusting
elements, without the user wasting time or discomfort during operation.
With rapid adjustment, the user can start working immediately.

In order to position the brushcutter correctly in the harness, make sure that it is in balance
and does not touch the ground.
To balance the brushcutter in relation to the harness and height
of the user, you will need to perform the following maneuvers:
- make sure that the belt is located one palm width below the
user's hip
- position the brushcutter in the safety of the harness and leave
it free
- if the brushcutter is not in balance and touches the ground surface with the blade or the
brushcutter tends to be tilted towards the engine you will need to reposition the located
fixing system on the transmission pipe of the brushcutter to the engine or the blade until
you find the balance point of the brushcutter.
In this case the operation will be done easily without supporting the brushcutter on the
hands.
6. FUEL SUPPLY

wires, mosses, etc. on the mowing surface, objects with which the cutting disc may come
into contact.
If you find such objects you will have to remove them from the surface to be mowed. At
the same time, unevenness or other elements that could endanger your safety during
exploitation will have to be highlighted by markings in those areas.
Careful! To be able to operate the brushcutter safely, you will have to read the user
manual and follow the markings on the parts of the brushcutter.
It is forbidden to use the brushcutter without a harness.
Make sure that before starting the operation, there are no people or
animals within a radius of at least 15 meters that you could injure because
at the maximum speed of the cutting disc through contact with the gravel
in the ground or other objects they can be projected .
