5.13 SAFETY RECOMMENDATIONS & PREVENTION MEASURES
• Do not operate the machine if anomalies that may affect the safety of persons.
• Keep safety signs clean installed on the machine and replace any that are missing.
• The maintenance, servicing and general repairs will be made only by authorized personnel.
• Observe all signs point to the work.
• Do not manipulate the safety devices under any circumstances.
• Ensure proper lighting for night work or in low light areas.

6. SAFETY RECOMMENDATION

•
Maintenance operations should be carried out preferably by persons who know the machine and its
operation.
•
Any manipulation of the machine should be done with the engine stopped.
•
Always consider the
recommendations in the engine manual
•
Grease every 80 hours the following, bearing supports (S, Fig.23) for the blade's axis, bearing
supports framebearing supports for the rear wheels, bearing support lifting (H, Fig.18)., spindle lift
and feed chain.-
•
Check engine oil level when the machine is always placed in a horizontal plane. Th joint cutter
engines are alarmed by low oil level, in a form that the level falls below the minimum, to the engine
will not start until you have added enough oil.
•
Use oil SAE 15W-40.
•
On models with electric start properly maintained battery terminals protected against corrosion
products for this.
•
The engine maintenance is defined as manual, both in the operations required, as in the time periods
to be performed.
•
Clean the machine as often as necessary and see if anomalies or malfunctions it inspected by a
qualified technician.
•
Be sure to remove the machine tools and devices used in each maintenance operation.
•
If the machine is not covered, cover it with waterproof material.
• It is prohibited any change in any of the parts or elements of the machine by the user.
6.1 TENSE & REPLACING THE BELTS
(C, Fig.24), transmission belts, are elements that with time of use enough loosen the tension below the limit. It is
necessary to periodically check your tension is correct so that pressing it hard with the fingers, the deformation is
achieved should be approximately 8 mm.
Also can be worn with the normal work of the machine so it will require replacement when damaged.
To check the belt tension, tighten or replace them, we will remove the protection (P, Fig.24) loosen the screws (T,
Fig.24).
To tense the belts, we must move the motor toward the water tank, for which, first and foremost, to loosen the bolts
that attach it to its platform (A, Fig.24), then loosen the rear tensor enough as to move the motor toward the water
tank, then pulled the tensor (R, Fig.24). Once we get the proper tension, put the nuts back as well as the tensors.
If what you have to do is change belts, we have to move the engine in the opposite direction to the water tank, for
thereby loosen the bolts that attach it to its platform (A Fig. 24) and the tensor (R Fig. 24) thus it totally slack and
can be easily replaced.
Then he will move the engine to the tank by pressing the tensor (P, Fig.24) to get the correct tension of the belts.
Finally pressed again the engine nuts and tensors.
Whenever you remove the protection (P, Fig.24) for an operation in the drive belts, it should also verify the correct
safety recommendations
