4. INSTALLATION INSTRUCTIONS
4.1. INSTALLING THE GRAPPLE
Remove the corrosion protection from the hydraulic cylinder.
Clean the rotator mounting face.
The strength class of fixing bolts must be at least 8.8 and that of
nuts at least 8. Check tightening torque table 6.3.1
After the first 20 working hours please check and tighten.
After installed the grapple, check the stability of the combination
according to standard EN12999 both by calculation and
experimentation.
Because of the risk of hitting objects the basic machine shall be
equipped with windscreen qualifying the local safety regulations!
4.2. SAFETY GLASSES OF THE BASE MACHINE
For forest use, the base machine must be equipped with safety
glasses because of the risk of timber hitting the cabin.
In excavators where the cabin turns with the boom, it is normally
enough to change the front windscreen and the sunroof. In
machines where the boom turns to the side of the cabin, also the
side windows and when necessary also the back window must be
changed.
In the EU, the minimum requirement is defined in ISO8084
standard. Safety regulations may vary and they must be checked
locally.
KESLA recommends using a minimum of 12 mm thick hard-
surfaced polycarbonate in the windows of grapple base machine.
When working always remember the
25 m
safety distance from
other persons.
