HARDI NAVIGATOR
Fig 58
NOTE! Use only genuine spare parts to service the
transmission shaft. For any other service or repair
jobs on the transmission shaft contact your HARDI
dealer.
Shock absorbers
If the shock absorbers loose their efficiency or start
leaking oil, they should be replaced.
Level indicator
The level indicator should be checked regularly. When
the tank is empty, the floater should rest on the stop pin
at the bottom of the rod inside the tank, and the O-ring
at the sight gauge indicator should be positioned at the
top position line (A Fig 59).
If any deviation is found, pull out the plug (B Fig 59),
loosen the screws (C Fig 59) and adjust the length of
the cord.

Cord renewal
If the cord on the level indicator has to be changed, the
float guide pole must be removed:
1 Remove the tank drain valve (Refer Drain valve seal )
and loosen the fitting holding the pole in position.
2 Pull the pole down through the drain valve hole untill
it is free in the top of the tank.
3 The pole can now be taken out of the tank through
the filling hole.
DANGER! Do not attempt to enter the tank - the
float pole can be removed from outside the tank!
Drain valve seal
If the main tank drain valve leaks, the seal and seat can
be changed the following way:
NOTE! Do not enter the inside of the tank - the
parts can be changed from underneath the tank.
WARNING! Use an eye/face protection mask
when dismantling the tank drain valve.
