Original instructions

Do not alter, modify or disable in any way the controls, safety devices, interlocks or any other part of
the machine.
Maintenance must only be carried out by appropriately trained and competent persons.
3.The effects of deviations from the specified performance on the safety function(s);
If the tilt interlock does not function as intended it is possible that the Niftylift may encounter slopes for
which it is not rated.
If the Niftylift encounters slopes beyond the rating as specified on the serial plate the product may
occur instability.
If the product becomes unstable, damage to the Niftylift, other equipment and properties, injury or loss
of life of the operator and surrounding persons may be a risk.
4.Clear descriptions of the interfaces to the SRP/CS and protective devices;
The tilt system comprises of a primary device the “tilt sensor” the booms down switch, and control
PCBs, and protective devices, for example solenoid operated hydraulic valves or contactors.
If the drive forward or backwards functions are selected when on the boom rest, the drive functions will
be available regardless of angle of inclination.
If the drive forward or backwards functions are selected when off the boom rest, the output from the tilt
sensor not being present will deny drive functions.
5.Response time
The tilt sensor is active at all times providing the correct signal in relation to the angle of inclination of
the chassis. In the event of encountering an angle of inclination greater than allowable the system will
prevent drive functions from being performed until the booms have been lowered on to the boom rest
and the angle of inclination has been corrected.
6.Operating limits (including environmental conditions);
All components within the tilt interlock are rated to the environmental conditions acceptable for the
machine; refer to Section 2.2.
7.Indications and alarms;
Tilt alarm
The action of the tilt alarm will cause the klaxon to sound and will be indicated by the red warning light
on the base and cage location, if the booms are raised and the allowable tilt limit is detected.
8.Muting and suspension of safety functions;
While the tilt sensor is always active the drive interlock is suspended while the booms are on the boom
rest. The angle of inclination having been exceeded will be indicated via warning lights regardless of
the boom position.
9.Control modes;
The tilt system has no user controllable modes of operation.
