5. MAINTENANCE
IMpORTANT:
Only fully qualified personnel should attempt maintenance or repair.
5.1.
When the jack is not in use, the saddle must be in the lowest position to minimise ram and piston corrosion. Turn the handle back to
its storage position for safety.

Keep the jack clean and wipe off any oil or grease. Lubricate all moving parts and grease tilt mechanism regularly including the main
pivot pin. See fig.1(c).

To check the oil level, fully lower the Jack. Remove filler plug (fig1-X). The correct oil level should be approximately 5mm below the
filler opening. If oil level is low, fill as required. Pump unloaded jack 5 or 6 times to expel air and then refit plug.
