3) Using a hydrometer, check the specific gravity of the battery fluid in each cell in each battery (Target
1.26-1.27 for DYNO Batteries when fully charged). If the specific gravity is not within the serviceable
range, battery de-sulphate fluid may be used to restore batteries.
4) Replace all battery cell caps and clean any liquid from the top surface of the batteries.
3.4 Hydraulic Oil
3.4.1 Level Check (Weekly)
Ensure the Niftylift is on level ground with the platform stowed. Check that the oil level is between the
minimum and maximum marks on the gauge. Top-up the tank with oil if the level is below the minimum
mark. Use the same oil grade as indicated on the label attached to the hydraulic tank. If the oil level is above
the MAX mark, drain as required. See section 3.4.4.
3.4.2 Return Filter Check (Monthly)
With the Niftylift running and the oil temperature at 40°C (104°F), operate the
telescope out function and observe the return filter condition indicator (located under
right hand canopy). If the needle is in the red zone, the return filter cartridge should
be replaced once the oil has cooled sufficiently.
3.4.3 Pressure Filter Check (Weekly)
With the Niftylift running and the oil temperature at 40°C (104°F), observe the
pressure filter condition indicator (located on the valve tray). If the visual indicator is
red, the pressure filter cartridge should be replaced once the oil has cooled
sufficiently.
3.4.4 Hydraulic Oil And Filters Replace
Replace the Hydraulic oil and filters after the first 500 hours of operation, then every 2000 hours or two
years (whichever comes first) thereafter.
Replacement or testing of the hydraulic oil is essential for optimum machine performance.
Contaminated oil and filters may cause poor performance and continued use may cause
component damage. Depending upon the operating environment, more regular oil changes may
be required.
Observe clean working practices when servicing the hydraulic system.
1) Ensure that the Niftylift is on level ground with the platform stowed and the oil temperature is not
above 40°C (104°F).
2) Loosen the filler cap to relieve pressure. Caution must be taken when removing the tank cap as the
hydraulic tank is pressurised.
3) Place a suitable container under the hydraulic tank.
4) Undo the drain plug located underneath of the hydraulic tank.
5) Dispose of waste oil in accordance with local environmental policies.
