Checking And Replacing The Flails - IBEA IB 562 Manuel D'instructions

D) CHECKING AND REPLACING THE FLAILS
Always check the state of the flails before commencing work. Do not forget to switch the
engine off!
Checking and replacement of the flails requires the assistance of another person to hold
the handlebars down to tilt up the front part of the machine.
The flails will be presented as shown in figure 10.
During work operations if the flails (Fig. 10, ref. A ) strike stones or stumps stop
-
straightaway and make sure that they have not become bent or broken. Damaged
flails must be replaced.
If the flails are very worn, cracked or bent, they make snap and project objects outwards,
-
risking serious accident.
It requires specific experience and suitable equipment to replace and repair flails.
-
- Use heavy-duty work gloves to check or replace the flails to avoid risk of injury to
hands.
- The flail fixing screws and relative nuts ( fig. 10, ref. B) are also subject to wear.
Always replace them at the same time as the flails, using bolts and screws of the
same strength and type.
When some of the flails are broken or bent they give rise to excessive vibration at
-
high speed.
The flails are reversible, so when they become blunt on one side they can be assembled
-
on the other.
- Generally speaking, unless it's a question of only 1 or 2 flails, all the flails should be
replaced at the same time to prevent the occurrence of vibration.
- Even the flail rotor holder (fig. 10, ref. C) may cause vibration. If so, it should be
replaced.
- The flails wear more quickly on dry, sandy ground. In these conditions they should be
replaced more frequently.
It is advisable to keep spare flails handy.
